I once converted a small block V8 into an air-cooled V7 with just a couple Taps of the rev limiter

My lotus elise has a K24 setup, 245whp and 760kgs. Fun :)

RB26 in a S13/14/15 is a honorable mention, probably too standard for these guys though. My favorite conversion ever done was not just engine but also drivetrain, one dude in his garage put a Honda K24 engine into a 5gen civic sedan, faded silver paint, stock wheels total sleeper, then stuck a big turbo on said K24, and then went through honda parts bin and put together a AWD system mostly off a mundane CRV. Then when he wanted RWD he just removed front axles rolled up to a drift track and drifted what visually looked like your aunt's grocery getter civic. It was sick. There was a video on youtube too.

Absolutely love these "Mass debate" videos. This is KZfaq gold. Stick with it I think it's gonna catch on when people realize how good it is.

Pleasantly surprised by how much I enjoyed this video! Nice to see open-minded, knowledgeable car enthusiasts talk about cool builds, regardless of how many cylinder.

The MCM VTEC Mini is hands down my favorite. Ive always been a sucker for classic Mini's, and that one is on my list of cars I have to see before I die.

I could listen to this for hours!Having knowledgable guys like you guys talking about their opinions on their passion is awesome. Lots of interesting points!

My favourite swap has to be the 1UZ in an AE86. Aside from that, being able to direct bolt-in swap engines from different regions that we didn't get here are always nice to see.

I like abusing old classics - currently fitting a 250bhp Ford ST170 engine in an MG Midget

Best: 3.5 Rover, Eaton M90, SVX auto into Mighty Boy (Mid engine track only). That was 3rd out of 130-odd cars at a hillclimb. A field that included a Group B RS200. It got beaten by the Skelta and a V8 Supercar, but not by much Worst wasn't an engine swap, it was a carby and th400 onto an EB Falcon burnout car. Technically it had an EL engine so it was a swap, but that's like an FG to BA swap, doesn't count. Still, someone spent time and money reducing the performance measurably. Bonus round: Strata-Garrett non-wastegated kit onto 202 in LJ coupe. 600 Holley suck through, 30psi on avgas, loose drivers seat. She was a wild ride, and I want it back

cant tell u how much i enjoyed this one Scott...highly highly entertaining.

Here in Croatia, we don't have much in terms of engine conversions. We're a poor country and parts are really expensive so doing any conversion is a luxury. What is really popular is Honda engine head swaps. People buy Civics with d14/d15 engines and put d16z6 heads on them. It's not much but with an exhaust, intake and a decent tune they can make 150hp. I know for you guys in Australia 150hp is a joke, but here that's a nice number. The worst swap I saw would be an RX-8 with a VR6 engine. The amount of time it must've taken to do it just to end up with a car that's worse than stock. To be fair, the original engine was blown, so it had to be replaced but there are loads of BMW and Audi engines available here which would actually improve the car, at least power-wise.

This mid west American boy been dreaming of barra for 15yrs i wish I could go down to the local junkyard n grab one for my rustang but i do have 65 falcoon 200 tri carb. Long live the six

Harley V2 in a Prius.

Nice video guys. I dig the format. Cheers!

back in the '80s Street Machine Magazine had a story on a Triumph T-R7 with a 308. I never saw it in the flesh, but loved the idea, as well as the clean panel modifications they made (turning the mid-line crease in front of the rear wheel arch)

Ford Crown Victoria Police Interceptor engine swap with a 6.8L V10 is one of the best engine swaps ever.

I swapped in a 1.9TD in my mk2 golf when the 1.6TD blew a headgasket...Easy conversion, looks stock, has some more torque and power. Not really a spectacular swap, but it works really nice.

Hope y'all do another episode like this it's cool knowing people's thoughts ✌️ keep up the cool vids big fan Haltech 🔥🔥🔥

Favorite video to date. Great format make it a monthly thing!!!!!!!!!!

A rotary will fit in just about anything. Rotary Bugs are pretty awesome. Rotary Miatas, Rotary Datsuns, Rotary Toyotas. Even heard or a Rotary Mini.

The barra engine talk gets me so jealous. I wish Ford brought that engine to the states. Seems like yall can get them from the junkyard for dirt cheap. I got an idea... Hey Haltech, instead of selling me an ECU, can you wrap up a barra engine, strap it to a pallet, and sell/ship to me in Hawaii please? Ill pay whatever it costs. Much appreciate it!

I've always enjoyed high high revving motor bike engines in a mini...decent power decent fitment crazy sound... Is this new format something we can look forward to in the future? Like the idea of guest opinions such a mechanical stig on different autosport topics... Also love the longer build breakdowns and some behind the scenes dyno tuning videos would be cool. Thanks for the videos and the awesome products haltech, my elite has been in my daily driver with zero problem for over a year.

Here in the US, an Inline 6 swap is either a 2JZ or a Cummins. Would like to see a Barra powered car someday!

1J and 2J into (older) BMW's are also a nice swop in my opinion.

K or F-series honda for sure. Boosted they're easily the best sounding 4banger around, almost sounding like a high revving raspy wrx. K24's can make 300whp aspirated with a head package and stock rotating assembly, revving to 9k revs and will take 600whp boosted, k20's have seen over 700whp unopened. Tough aspirated sfwd 2.7L k24's make over 440whp and trap over 145mph in a stock chassis full interior car. F-series wise a heap of 6-750whp builds on unopened engines and last like that for a couple years pulling 9500 revs. Real St ran a 9.4@156 in their s2000, pump e85, unopened engine. Worth nothing also kings performance made 1150whp on a stock port, stock cam, stock crank/factory girdle, sleeve/piston/rod & only build and ran into high 8's with IRS, then later made 1350whp on their off the shelf head packages, stock cams still & same short motor running 8.1s @ 171 with a live axle. Cant beat a good combo, only real downside to them is the open deck & needing to be sleeved above 6-700whp mark...

Love it guys! This is a great video!

This was cool to watch. Loved it.

boosted k24 in a sw20 mr2. perfection!

Audi or Volvo 5 cylinders with big turbos in anything cool. Great torque, orgasmic sounds!!!! Volvo needs better sleeves, but who want's do a half assed job anyway?!

hell yeah guys!! great video love to see more like it!!!

i like these discussions guys,so much engine knowledge here,started watching mcm about 2 years ago thats how i know scotty and benny(aka tuningfork and mechanicalstig;-))love you aussies always honoust and helping each other and don't get me started on the rich car culture there and the fact that mad max excists😏✌️ Keep up the great content guys i'm loving it. ps: i got a engine swap in my car,nothing fancy it's basicly the same engine.i have a 2005 manual audi a3 quattro 2.0tfsi(200hp AXX-engine),it now has a s3/ED30(BYD-engine code) engine swap in it with I.E. con-rods,better bearings,loba cnc stage 1 head with supertech valvespring kit,loba hpfp,ttrs lpfp with ttrs controler,loba clutch and flywheel kit,TTE420 hybrid turbo,larger intercooler with better piping,fluidampr crank pully to compensate for the extra vibration from the single mass flywheel.okada ignitioncoils,gaped sparkplugs 1degree colder then stock,HPA intake,was the first in belgium to have that intake on a 2.0 tfsi which deletes the stock intake flapper adjustment(economy stuff),and probably some more stuff i'm forgetting,swap was fairly straight forward.resulting at 414ps(420hp) and 545nm(401lb-ft) at the engine here's the dyno run link: m.kzfaq.info/get/bejne/rsiZlt2fzteUl2Q.html

I'm still longing to see a 4G63 powered GT86

4g the world or barra everything

Great vid love the talks : )

Great series, keep it up!

Best engine conversion: anything weird and uncommon. Not worst but boring: LS into anything. Absolutely worst: people in Sweden who dieselsswap their old volvos and have to put the godawful D24 "Volvo" diesel in it. There's lot of good engines to choose from, but still they choose the head-cracking, crank-snapping, thirsty, low powered heap from 1960's VW...

BMW S62 engine in a 1970's BMW 2002

My favorite swap has to be a Honda k24 block, k20 head, turbo, MID-ENGINE, RWD, Honda del Sol. Waaay over the top as far as cutting, fabricating, cost, etc. BUT I've always had a soft spot for the del Sol and everyone has to admit a 2k lb car with 600+ hp at the rear wheels (the correct ones) complete with turbo noises would make for a very fun and exciting car regardless of whether or not they are a fan of Honda's

This video style is great, if you can definitely make more of them

do more of these talks :D

I like everything JDM and across my time in America and even across the world, I've seen tons of amazing and great swaps & mods that actually sounds cool or works. USA - I drive a NA1 NSX with a bolt-on supercharger making ~375hp during my time in 10 years in America (My relative is an American immigrant) and my friend and I went for a drive during summer break and when we went to the Vegas Dragstrip, there's this amazing 1997 Series 1 Lotus Elise with a B18C bored to 2L and with a bolt on supercharger too making 280hp and with the lightweight, the little Elise flew down the 1/4 @ 11.42 sec. Amazing little pocket rocket. Australia NSW - This was an oddball really. Saw this in 2007 and it was a Holden Premier HX and it had a bunch of dumb things in it. It's a 1JZ conversion but a BNR34 turbo sets (I don't know how that works) and claimed to be cranked up to 332Kw (452hp) and the exhaust system was dumb as heck often sounding like a rifle going off. Australia Warwick - Saw this in 2007 also but it's a AE86 with a F20C in it and it..Sounds.... WONDERFUL! It was at a track day at Morgan Park Raceway and watching the thing doing it's lap while sounding like a screaming banshee is nice. Malaysia - This is across my border and this was just recently where a street built 260Z Fairlady had a RB26 tossed in. It was a imported Tomei N1 spec block and with it makes about 500hp fully done and it could fly down the highway at 262kmh for 10 mins reliably cutting in and out of traffic with no issue. Even a R35 GTR has issue catching it. Too bad the car was stolen and never got found. (I know the owner by the way. He passed away at age 53 from a heart attack last year) Worst engine swaps that I ABSOLUTELY hate the most is LS swapped RX-7s be it FC3S or FD3S. I mean, sure. They work better than the rotary 13B but the reason with the 13B is that they could make more with way less and nothing sounds better than a 13B blowback and the mighty sounds of "BRAPBRAP". Plus, LS swap RX-7s are just so fuckin' generic. Come on man... Stop that

i've thought for ages how cool a Suzuki Cappuccino engine in a Suzuki Mighty Boy would be. not too over the top but a tiny lightweight rev-happy turbo mini-ute would be pretty mad

WRX Subaru in the back of a Hillman Imp with a 2 wheel drive box and flipped diff. It fits very neatly with out any body mods.

The reason you guys hate Subarus in VWs is because your build did things the hard way. The advice you got from your expert was rubbish. Made me cry to watch it when so many guys were doing it right. All the SOHC EJs fit with very little trimming. DOHC motors fit fine with the Subaru trans as it moves the whole drivetrain forward a few inches. I've owned both aircooled and subaru powered VWs. The Subaru was a lot more reliable.

My least favorite engine conversion is an LS in an RX7. For me I think you shouldn’t buy an RX7 if you don’t want to deal with problems that come from a rotary and plus for the price of an LS and all the stuff to make it fit than you should just buy a rebuild kit for the rotary to make it reliable

Awesome video!

not a VW guy... But gotta love the twin VR6 engine setup in a VW Lupo. Sounds amazing as well!

Mate, you are so right about Honda engines..they rock.

Im a big fan of the toyota 4500cc straight 6 from the 80series landcruiser; destroked and turbocharged. There was a drag supra that used the setup, i think its a beast.

What a brilliant channel :)

We think this was an awesome video! More debates guys!

0:15 The opening animation are all Canadians!!! XD Guess you guys are Terrance and Phillip fans :D

Well every engine swap is nice cause you see what people are passionate about!!If they build a car properly and they like it its OK from me!!BUT AY NO V8 IN AN RX-7 FFS SICK OF IT ROTARYGANG

Ford 6.8l 3v V10 Motor in a 2003 Mustang is probably my favorite engine swap of the year and my favorite car to drive as well. Put a pair of nice Junk Yard Diesel Turbos on it, Rebuild with Forged Internals, Custom Long Tubes Headers, Custom Straight Piped No cat exhaust, and Custom Intake equals over a 1000Tq to the rear wheels. Had it at 174MPH in the Half Mile before I backed out of it and blows thru tires so fast that you need a new pair every other week. Not to mention I average right around 6 Smiles per gallon of E85 and 11 Smiles per gallon on 93 :) Second Favorite is a Ford 2.3l Ecoboost from a 2016 Mustang in a 2004 Mazda RX8. A guy at the local Cars&Coffee did the swap and this car with this motor makes for a very fun time. More Power, better Reliability, Better MPGs, and more torque than the factory rotary engine makes the RX8 a totally different car. One of the best swaps ever for an RX8 besides the LFX and Chevy LS swaps. Next is a Honda K24 in an 02 Toyota MR2 Spider making 300WHP All Motor. This is one of the scariest cars to actually drive when you start adding power to it. Stock and Swaped weighs a little under 2200lbs so any power increase is going to feel like a big improvement. The guy that had it made a C6 Corvette look as slow as a prius and even beat an FBO 2016 Mustang GT in the same manner. Worst swap I've seen is an RX7 with an all motor LS7. Normally I'd be all for swapping a Rotary out however in this case it was too far. I'm not a Rotary guy by any means and only recently started warming up to the idea of one however when you think RX7 and Engine swap the only thing that should ever be done is a built up rotary engine with a High as hell 10k+ Rev limit and a Nice big Turbo. Nothing else should be done to an RX7 and anyone who has stuck anything else in one needs to be shot and the RX7 rescued from that hell.

Lots of great comments on here, to me certainly depends what application and what car. I've recently put a big accord motor in a civic as a cheap track car just for something to do while I study. I've seen some e30 BMWs with some neat 1j and N54 swaps recently. Also really like the idea of newer LS motors in older cars like 56 Chevies etc.

There is diesel swapped 180sx somewhere on KZfaq, I can't look at it for more than 10sec without swearing.... In fact I'm loosing my shit just thinking about it.

I should put a Barra engine in my Valiant! It'll almost become a Barracuda!

Rotary in a Torana would be the best part of the car... LOL.. Especially a 20B. Epic. I love how he took the "Mazda Bait" :P

The Ferrari swap in the 86 the engine cost more than the car cost new.

Rotaries are a thing of the past,, most IP racers are using piston/ turbo engines. In a Torana? sacrilege though a few put them in Sports Sedans. And probably went slower! I went Chev, cheaper faster and far more reliable. As for conversions I know or have done? Corrolla into an early Diahatsu 4wd. 308 in LJ, 308 in Bedford Truck, 318 LA into a D5N Dodge that started as 245. 350 into HX LS, 318LA into a Rambler Hornet. Ones I have known,, Holden into Morris Minor, MGB into Morris Minor, Holden into Anglia, Holden into Simca, Holden into Kombi Van. 454 into Transit Van, 427 into Austin A90, Cleveland into a Sigma [and Windsor as well] 289 into MGB. SBC into EH by about 6! All of these on the road. Then a bit more wild Holden into Honda S600, 2 litre Ford into Honda S600. Chev into Honda S600! Morris 1100All by the same bloke. Holden and Chev using Jag rears. 454 into LH. Rotaries into Escort, Corrolla Anglia 510 Datto and LC Torana. Chevs in Escorts, Alfas, and more.

Saw a video recently of an Infinity G35 with a 2JZ swap... love it

I've always loved Eric Plebani's 198x Porsche 964 with a Mitsu 4g63t engine in the back. There are a few 1g awd dsm's and at least 1 r52 mini cooper s that have twin engines each driving 1 set of wheels that are marvels of engineering.

I'm laughing my ass off, "thong slapping", I'm watching the video and my gf is beside me on her phone but half listening to the guys talking- "thong slapping" , in Europe a thong is underwear like a gstring. And she asked "why are they slapping women's underwear?" lol

On USA KZfaq someone put a 283 cu in in a 60's Ferrari, had found an original V12, but numbers didn't match. So put a a a a a pushrod cast iron V8 in........WHY?!?!

I loved this :)

I love sacrilege aswell! Currently putting a K24 in an AW11 MR2

Worst conversion I’ve seen was a Cummins Diesel engine in a Nissan skyline. I believe it was an r32

The VW 12v VR6 is one of my favorite swap engines. They are starting to get swapped into non-VW cars and trucks, usually with big turbo's. Head spacer, main/head studs, upgraded rod bolts and they will handle 600hp easily. K-series in an NSX is my least favorite. Can't sell me on it. It's just a no from me.

Still curious about the 1GZ FE V12 set up problems- stock the engine has two computers, each independently running one bank. How was the engine liberated from the Century chassis and what sort of Haltech "puter was used?

Best: Escort mk1/mk2 - Cosworth YB turbo or NA Worst: VW passat - any vw tdi engine Great video! make more like this! people with actual skills and knowledge should talk more!

It's all about the t5 for me . You can get them for free and make 600 bhp with about 3k of parts. Pluss its reliable Volvo are sick. Volvo rwd boxes are getting rare but there's kits to run bmw box's and they are like £50

No hybusa smart car

You could run hard in the ol' K-26's too - Dunlop K-26! A mate dropped an E-37 spec. 265cui hemi, into an Lj Torana, or rather shoe-horned it in - modified fire wall, removed engine fan, reversed the thermo fan for extra clearance, and the Bolt heads of the fan pulley still nudged the radiator fins when the throttle was stabbed! And went like the proverbial 'scalded cat'!

The Ford 4V Mod Motor is seriously underrated. I think the whole 4 cams thing scares people off and they are wide so they are always a tight fit but they are becoming affordable and make easy power. Mod Motors hold 2nd spot for quickest factory motors just behind 2JZ and the really quick guys are making over 3000hp with sleeved factory ally block, ported factory head and mostly factory valve train. In NA form unported cam swaps and tune have seen around 400rwhp and the top builders have achieved over 600 at the rear wheels. A V8 that can go over 10k rpm or over 7k rpm with the stock crank is a pretty sweet thing.

Best engine conversion. The JUN-Synergy-BRZ with the custom built V8 made with two Kawasaki engine blocks with custom crank. Worst and biggest sin of engine swapping. LS swapped RX7s >:( Something odd yet cool. The AE86 with a Honda S2000 F20C engine. = Holy cow! o.0 Ford Barra powered Nissan/ Toyota. = Cool Full VR38DETT swapped Nissan Patrol that destroyed a Porsche 918. Holy wtf! And funny. Muscle cars fans will kill me but I love the RB26 swapped Mustang in FnF Tokyo Drift.

I helped put a Honda 1.6 in a Smart Roadster Coupe!

I once installed a worked 5MGE + manual gearbox conversion with an aftermarket EFI into a 1977 Toyota Cressida MX32.

Mass debate, classic haha! Wtf86 is pretty cool with the stroked vr38 makin 1000 at the wheels. Beasty

favorite swap: RB26 into 350Z. Least favorite: Chevy LS into any Ford.

om606 swap into a JZA80

when i broke my 5 speed for the 4 cylinder i put the stock 6 cylinder that was offerd from factory in my truck. does that count as a swap? i wanted to do 22r but i found my donor truck for less than what a good 22r cost

I can't wait to install a Haltech Elite Premium ECU into my 7AGE-HR 1.8L AE86 Coupe! Wish you guys could've been at Formula Drift Atlanta!

K20 in everything

K24 in a Miata/mx5

Tunning fork must love the turbo honda k series swapped smart car fron Fasterproms! Awesome build.

I loved the discussion , i AM from Brazil And here we swap the AP engine of the VWs and put It in everything (including the beatles ) we also make the Subaru engine swap with the beatle Around here.

Beams swapped corolla

Worst 20B E Type Jaguar Best k20 AWD classic Mini

So glad my FG Mk2 XR6 ute has the Barra. Will probably end up getting a turbo on it, but 450-500kw atw would be extreme after about 150kw atw stock!

Worst engine conversion was some guy (muppet) fitted a holden red 6 cylinder into an XW GTHO Falcon, sacroledge. I personally fitted a 429 Cobra Jet motor into an XB GT 2 door hardtop with a big spine toploader, a bit of a worry into a corner though due to the heavier engine. I must admit I did like the Honda engine into the Mini that MCM did.

LS swapped RX7 worst swap .rotary power 13b20b26b💪more braps on this channel please 😍

If you say a Rotary is unreliable your just dumm! If you treat it right give it its oil and service and it will be the most reliable engine you will ever have!

I had a B18C5 top end mated to the B20Z2 bottom end with a Jackson Racing SC in a 2000 CR-V sleeper... best thing I had ever put a spanner to... until it was stolen and stripped down to the metal in 2012. I will never be the same.

I'm doing the 1jz to mx83 cressida swap at the moment and have a vvti 1jz in a ma61 supra too love these engines

best swap: ls4 single turbo 5.3 v8 into an acura rsx, big v8 in a small car worst swap: 2jz in a gallardo, like wtf

b is for build m5 engine in 240z

I remember Street Machine Magazine fitting a Red Motor to an XY GT. And I've seen a 253 in a Corvette.

Did you guys get any of the Italian cars in Australia? I'm in Utah USA I've got 2 Lancia Scorpions.. and I've owned the Fiat X19's also.. That Honda K24 swap is about the best for those cars considering the purpose the chassis was built for, IMO. Killer! I've got an '89 Conquest(Starion) and I wanted to put the Barra I6 turbo swap in it once I'm ready to swap.

Barra the world!
