For every member here, also for a brand, we learned a lot from D4A's videos. Every video of D4A is always interesting and inspiring. Thanks D4A for making such great content. We feel honored to incorporate MaXpeedingRods products into your projects.🔥🔥

I’m glad my video helped you out in terms of info on these turbos. Appreciate the shout-out!

Great idea to do a real world test with a budget turbo before settling on a bigger brand turbo, very smart and financially savvy.

I just want to thank you for making these video’s. They are in depth AND easy to follow. Your dry humor make them both informational and enjoyable to watch. 🙏

Driving 4 answers is far and away my favorite KZfaq channel now. I have been a big fan of Engineering Explained and I still love it, but I’ve learned more from D4A than I have from any other channel. Awesome, awesome stuff. Keep up the excellent work!!

I just wanna say you have great filming and great information. I'm excited to be here and watch this channel thrive as it deserves!

Massive congratulations again on 100K subs man! Seems like just a few months ago I remember you passing 10K. So far, my experience with budget turbos has been quite good! Really awesome you're working with multiple companies on this upcoming build. :)

It’s amazing how good these are getting!

I love your videos man , there so informative and full of knowledge you cover every inch it seems like and at such a down to earth level. I been watching your videos for a couple months now and I just wish I discovered you much earlier. Thank you so much and please don’t stop as I and so many definitely want to keep seeing! D4Answers all Day 🤪😛😁 👏

Sold my aw11 last week. I'll still stay and support the channel. Love the content and how your mr2 has evolved over the past years.

best day of the WEEK thank you again

I swear I've just begun the same project. Just sourced an FE intake to mount onto my 4AF head... And my cousin is hooking me up with a turbo off of his mk3 Supra. Budget builds hey. Literally just started the build and now I see this video 😁

I am learning a lot from your videos. Thanks man, keep going

Please don’t stop making these videos man!!!

hey mate, congratulations on 100K subscribers, you deserve it ! :) cheers from Australia :)

Ive been looking forward to this

Great videos and content. Keep it up mate!!

Awesome. 101K subscribers will be following.

I am really looking forward to seeing how your setup performs and I hope you're happy with your build.

Cool video & idea! Can't wait to hear how it goes. Subbed

you should consider setting up a community discord!

Looking forward to this series!

Looks awesome dude

You're good tuner. I like the way you think. Common sense. Keep it up.

Amazing video. Thank you brother

I feel like I got into the mr2 hobby at the right time because he makes all these videos right when I need it.

Recently got a newer car and I have the same engine in my corolla. I was planning to mess around with it until it blew up, but idk, might rebuild it and make it my weekend warrior. Deeefinitely gonna keep up with your awesome videos man

Dude i looove your Videos! Looking forward for more...

My brother purchased an MR2 stock when it came out in the mid 1980s. As you know, it was a non turbo. But, you could hardly tell because it ran like a rocket. It was really fun to drive. Nice car mate!

Great informative video, as always. I still await the update on your current experiment with your 4A regarding solid crank pulleys vs dampening crank pulleys.

You and Richard Holdener offer so much information.

Great work on your channel and all of your videos. I am all for budget builds vs exotic and unreachable. I am using a ct12b turbo on a 2E-telu starlet ep71 and its sized perfect without creating restriction!

I had that on my 4agte, started making boost at 2500 RPM. Honestly wasn’t bad driving around

Thank you keep up the good work

Wish you would do VW mk2 8v turbo build - you are the most helpful vlogger for turbo newbies right now ! Tubo controls videos was great!

Thanks for the info!

Love the videos

Great project, hoping more videos about, good one

Great video's! not very many people have such great info with a not very sober envirement

awsome, somehow you always do what i want to do, I really hope you hook the turbo up with the existing carburetors, at least just to try it out. your videos are great, i always look foward to seeing your videos

This will certainly be a large turbo for a 1.6L I am looking at getting this size to upgrade my 4th gen 3sgte in order to hit 400hp+ The 4AF will be an interesting turbo motor though with that narrow valve angle it should take forced induction like a champ. Will be a neat build. =D

Thank you for another brilliant, informative and enjoyable video. It's always a pleasure to watch your productions! For the price, this product looks impressive and is very tempting. A used turbo with unknown history could easily be the same price. The comments about manufacturing quality and potential for failure do have merit - but a turbo from any manufacturer could suffer failure because of a manufacturing defect, oil starvation, overheating, or debris entering the system. The warranty would be a crucial thing to consider - because I imagine most aftermarket engine components will only be covered if it can be proven that failure was caused by a manufacturing defect and not by poor setup/maintenance. This product has me a bit baffled though. You're right - they have to save money somewhere, but after going to those efforts on the turbo itself, giving you incorrect bolts and poor gaskets would set you up for a failure and spoils your experience of the product. Could it be that the turbo is manufactured and checked in one place, then packaged with those bolts and gaskets from elsewhere? It's kind of concerning because, 'as received' the product cannot be used; and does the warranty cover the use of other bolts/gaskets that are necessary? I wonder if maXpeedingrods would offer you the correct bolts/better gaskets? You have given me a new option to consider though. I'd like to make a turbo build one day and something like this is now a strong consideration over having a used turbo rebuilt. The video from JK Fab is a good addition too, and as you say, beneficial for you to see the balance and quality before you bought it yourself. Thank you once again for a great video, and for putting up a makeshift video in your road-side garage which may not be that comfortable to do videos in.

this is call smart tuning this guy in really intelligent

I have a 1.8 turbo Audi. I replaced the factory K03 turbo with a $100 Ebay K03 and currently have about 4000 miles on it and only 1 issue. The old turbo pushed 21psi, the Ebay turbo at WOT hits 25+psi then I hit a over boost limiter of sorts and it drops to 15psi and holds. I can hear the blow off when it happens. Needless to say I don't go wide open much. Planning to rebuild the factory turbo and put it back on...

only thing i can say is instead of the 4afe you should do the "stroker" 7afe, they pair well with a turbo.

I love a well dimpled crank.

That was a fun video, actually LOL time. When I saw MaxSpeedingRods ad a few months ago I thought it must be a misprint. Even though I too would choose turbo over night out, my wife would probably kill me if I bought a turbo instead of taking her out to eat

One thing to remind certain car owners. Just because the turbo was cheaper, does not mean the labor to install it will be cheaper. As he noted, it had improper gaskets and fittings. No shop with any sort of a decent reputation is going to install those shit gaskets and some won't have spare banjo bolts just "laying around". I very much agree with everything stated by D4A, but, like him, I can do the majority of my fab/install work. If you can't, don't be mad at the shop you take it to when they rip this thing as a crap kit.

I would love to see videos on learn to tune cars, starting from a safe point and doing small increments to improve power until how to determine the limit and stay in a safe reliable set up

Supercharger history!!!

Looking forward to the "selecting a turbo" video. Have a 1.6 as well but it has a super long stroke with barely any bore so it doesn't rev high but makes as much torque as a 1.6 can down really low. Was thinking a gt25 or maybe even smaller. The goal is boost around 2-2.5k for daily driving. Don't care about top end. Keep up the great work, love your videos man!

I've been thinking about grabbing one of these for my KA-T build 🤙

Agree you have a Good Review

One guy is using a budget turbo on his 1.8L Cruze. So far so good. Just cost a ridiculous amount for him to have a exhaust header fabricated.

4A-FE: Stop talking shit about me, just wait till I glow up!! This guy: "We're going to watch your career with great interest"

Nice! A discount disco potato. I remember alot for one during my sr20 days

Funny that your video is talking about the exact same brand as my coil over suspension.

MaXpeedingRods suprized me with the quality of their rods for my ej25. I am leaning to buy their turbo too

I paid $325 for my turbo almost 4 years ago. It is even faster now then when I first started setting it up to make power. And turbo is still in good shape. No play or leaks. We live in an amazing day and age.

Nice video, will there be porting the head and testing different toyota intakes? Maybe even itb setup?

Thanks for the info, great video. Do you maybe have any experience with replacing OEM turbos with different variations; new OEM, renewed OEM from shop, renewed original turbo from your car or new turbo from other manufacturers like Nissens, Lucas, Mahle, Magneti Marelli, ... what are good options and why?

Those gaskets look fine installed a gtx 2867r gen two two weeks ago gaskets looked the exact same

I have this exact maxpeeding rods gt2871r on my 2007 fiesta 2.0 duratec (st150) I did away with the internal wastegate as the actuator wouldn't fit against the bulkhead, so I went 38mm external wastegate. it was only a budget build costing me around £2k including mapping and made 285bhp at the flywheel, it is a little laggy but that's good as the engine internals are stock and to much low down torque is what destroys the stock rods, all in all im very happy with this turbo for the price

One thing many people don't consider when looking at a chinabay knock off turbo is sure you could replace it multiple times for the cost of a name brand unit if it dies. But a compressor wheel shattering at 100k rpms can easily cause metal scraps to make their way into the motor and destroy that along with itself. Now the money you thought you saved is gonna cost more than the big name, warrantied turbo was replacing the motor. I'm not saying you can't find a good deal on eBay or elsewhere. Brands like kinugawa and tomioka seem to be well built and properly balanced units for half the cost of a Garret or Borg Warner. Research is key to getting a good deal on a quality product.

My son had one of these budget turbos fitted to his Audi TT, it lasted 3minutes! On inspection it appeared the bearings had failed and the engine ingested metal debris causing major damage. Now he may have been unlucky but I'm a great believer in "you get what you pay for". He payed with paypal who refused a claim on the grounds the item was modified? So caveat emptor folks!

I see a small hole for oil feed. Is that a build in restrictor?

A 2860 turbo will be a much better choice, unless you are just drag racing. Look forward to following this build.

Street racers don't need girlfriends. Only turbos

Definitively bang for bucks there! Damn a much easier 2T cylinder and piston costs 2/3 times as much...

This is quite usefull because I'm looking for a turbo for my 1.6L K4M Clio 2 engine.

THANKYOUUUUUUU

This turbo you have you can run for 2 minutes per half hour. But with the Garrett you can run for 15 to 18 minutes per half hour. That is you can run Rally or drag racing, but you could be drift racing with the Garrett. And of course by running the turbo I mean doubling your atmosphere inside the combustion chamber during intake. Allowing you to run on an air flow sensor instead of an air pressure sensor although I still suggest both.

my friend please port the wastegate hole, I'm having issues with boost creep, the turbo works great but I don't have control on the boost pressure, I have to disamble all again and port thata hole, and thanks for your videos!!!! I have the same turbo on my car

Did you notice that the t25 inlet flange is much smaller than garettes specifications where all the flanges are made from?

How am I JUST NOW coming across this channel

You need to port out the wastegate passage hole with a carbide burr and a die grinder, (I recommend using an electric grinder as they have way more torque than an air die grinder) they are very small in these turbo's, plus replace the watergate actuator as they have very strong internal springs which will not work well with sensible boost levels, 10 to 15psi. These actuators need more like 30psi to fully open the wastegate! Boost creep at high rpm is very common because of this. After that the 360* bearing is a good idea if you can find it very cheaply, however it probably makes more sense just to modify the wastegate passageway and fit a better actuator and leave internals as they are since its a cheap turbo and if you need to replace it later down the road just buy another and swap over your modified exhaust housing and actuator for a small price. Liking your videos, would like to see you make a video on the BDA/BDG engine, if not also the 2.5 Millington found in mk2 escort rallycars that have become legendary in the tarmac rally 2wd world esp in Ireland. Ken Block has one in his escort. Kind regards Jason

iv fitted one of these gt 28 on my bmw k100 bike with good results so far not a bad turbo im on a budget and cant afford 1500 dollars to throw at a brand name turbo i thought this turbo wasnt bad for what it cost me

I am interested in adding a turbo to a 4.0L Jeep Grand Cherokee. Can you give a rundown of the DIY list of steps to address and comment whether this turbo would be a good fit?

Will you use the oil restrictor? or not on this journal bearing turbo I heard that journal bearing turbo don't need it just the ball bearing turbo use the oil restrictor but I wanna know what you'll do?

Hey there man. I guess this is a little off topic-ish. But I don't know how else to get ahold of you lol. I turbo'd my 3g eclipse with sportronic transmission. I'm tuning it myself (or trying to) using EcuFlash and the tactrix 2.0 cable. I was wondering if you have any experience with it? I'm trying to make my auto ecu identify boost (engine load greater than 100%) I think I may have it, or I'm like half way there, but I don't know for sure(I have my maps edited and showing 10-180 engine load, but will the ecu actually understand it?).... I'm also running a MaxPeedingRods t3/t4 .63 a/r turbo.

I have a Maxpeedingrods turbo on my Saab pushing 300hp, its not bad for the money.

Percentage of worsness= difference in rpm it can sustain, turbo efficiency chart, pumping losses/drag....I think there are LOTS of ways to measure the difference between a knock off and the real deal. But I agree, tje cheap one is better bang for buck!

It would be awesome if you do the same but for super chargers later on, everyone talk about turbo but on circuits with lots of curves a supercharger is far superior in terms of stability. Its quite interesting its oil and water cooled, btw if i recall correctly you have to make the valve hole bigger on that turbo or it will overboost, nvm lol.

What made you decide to move away from the 4AGE? and is your base car a SC or NA AW11?

That seems pretty big for the MR2. Might make your peak numbers, but will likely be mostly lag, followed by too much boost? That said, cheapie turbos are generally a good value. I ran the Garrett GT28xRS on my 1.8T Audi at 25PSI but on a 1.6 not built for a turbo? I used one of the cheapie ebay turbos as a replacement on my wifes Audi and it worked just fine (K04). There's a website of a guy in NZ or Australia (don't have link handy) that has lots of good details on how to make power with the 4age

If you do a "how to pick a turbo kit" video, can you please maybe incorporate tge toyota 2ZZ-GE? I want to turbo it, and i know it doesnt like lots of boost. I think the 2zz would be great to make a turbo video for as it has limitations that people need to look out for.

Boznie; congrats! Your just like me. Two seat, mid-engine, coupe. Forced induction is much better than your bike carbs! I have a TPC racing 2nd stage turbo 2.7 Cayman, 5 spd., 380 hp., with Fab Speed high flow cats. You asked for engine topic suggestions and I think the M97, could be a real nich for you. Lots of Porsche guys have very little available information. 🤔😏😄👍👍🏁

Hy I have a 4afe engine that I'm planing to add a turbo but iam not quiet sure will the stranded engine take the boost or not ......welll my question here in ur video is what things did u modify in the engine while u add that turbo....things like piston ,bores,what connecting rods to use what piston to use n etc ???... please make a video n tag it to me please

cheap ebay turbos work great, had one now for 20,000miles still working great... IMine is the same as shown here!!!

12:30 nice truck sound

The 4afe deserves some respect. What exactly of the internals have been altered sir?

can I cut that big chunk of cast iron off the exhaust housing ...it's hitting my engine block

Next up, valves and setting up a Speeduino

8:30 question, does the most important part - the bearing - have to do with spool up times?

please also make a video like this for a budget supercharger too!

Cheap parts are great for learning, I will shortly be on my 3rd and hopefully final set of maXpeedingrods coilovers. It would be awesome if they would make a ball bearing turbo. I'm sure it would still be far cheaper than the big brands. Even if it's $350 instead of $150 that's still way better than $1,000+

The Garret could easily be 10 times better if the budget turbo only lasts 5,000 miles. Would be interesting to know if anyone has put many hard miles on the budget turbo successfully.

Where would you get quality gaskets and hardware for this turbo?

Should I boost my 1999 Jag 4,0 v8?
