def ECU, then its valves and cam combo, last is a 4-1 headers With the standalone ECU. any mods will impact the engine performance greatly. Esp the valves and cam. You can engage the VVT early or later depending on your preference. 4-1 header for the 4AGE 20V will make it screams louder in the higher rpms. Making the throttle blips more enjoyable.

Your videos are getting better and better! Definitely go the exhaust first, let that 20v sing.

That engine note is to die for, also i love the music you used for the video. Great job :) I want a Sushpants T-shirt.

I am glad that I found this channel. A real gem.

your content is awesome man! keep on going :)

Installed my mrp coils last week, an absolute treat compared to the blown original shocks. Very good upgrade, glad you too are enjoying them. And oh yeah I want Sushpants t-shirt!

Not gonna lie I'm loving this channel

Love the sound of this thing. I’d say ECU from the get go, that way any mods you make from here on in can be managed and configured with more flexibility.

It sounds so good! 😍

I just ordered a set of MRP coilovers for my AW11 because of this video!

Your vids about this corrola are much better than 2k+ super cars vids

Awesome video buddy! One of your best videos yet. Plus i would totally rock a sushpants shirt lol.

Love the sound of the twin cam btw😁

I always loved the FX16 & AE92 coupes...clean car

great video, nice and quick compared to some of the other youtubers who would have turned this into a 30 minute video with 6 ad breaks haha absolutely perfect car, one of my all time favourite Toyota's I just really love the accents they added to it. I want a sushpants t-shirt!!

The long awaited video had arrived great video man

I like ur videos alot cause I'm a big corolla fan. I'm driving my second corolla after I sold my first one. I just love the way they drive. My second corolla is a upgrade from my first corolla.

Exhaust first...cams next. I'd love to have a Sushpants shirt to wear while driving my FX16 GTS! Keep spreading the love!

I've fixed all the small component seal oil leaks and started upgrading my 97 corolla bz touring wagon. It's got a swapped c160 lsd 6mt to go with the blacktop (which i got painted bright pink with MANY different sparkles haha) love this car and will be getting some coilovers soon for it once I've got my new grill and installed my new headlights. After that I plan for the MRP willwood brake kit and then many engine upgrades using MRP parts (I live in New Zealand myself so it's great being close to the guys here) Love your channel and its helped me so much already. Also "I want a sushpants T-shirt" ♡

I'd go with I WANT A SUSHPANTS T-SHIRT. Sorry, couldn't help myself was just to excited to maybe win a shirt. I go with valves and cams.there are tons of videos already on exhaust systems. It's rare to see anyone takle NA power gains in the detail your videos are known for.

Your videos are awesome, you've made me want an FX-16, currently in the market for one. We need more content! I want a Sushpants t-shirt.

Rad little car you have man! I reckon go for cams next 😏 and I'd love a sushpants shirt too! 👌

I want a suspants tshirt! Man how did I miss this one?!! Benn looking forword for your coilover install and it came out just as expected! I want to get some coilovers for my corolla as well!! Keep the videos coming!!

Awesome! I’m gonna start upgrading my fx as well!

keep up the good work bro!!

I think ECU as it'd be great to see the difference over the stock ecu without the other mods. Awesome video dude, stoked for you. Would love a shirt. 20v ftw.

love the review. definitely gonna get those coilovers for my FX16 GTS in the future. also, "I want a sushpants t shirt"

Such a unique build! ECU and I want a Sushpants T-Shirt!!

Man your car gets better and better! I'd personally do an exhaust for an even better sound, but be careful because it's a 1.6 so it's easy to fall in the trap of a "fartcan" exhaust, which nobody wants for obvious reasons. Also, I want a Sushpants T-Shirt!

Standalone! The stock ECU really holds back the 20v or so i hear. I want a sushpants t-shirt!

I'm from new Zealand and it is good to see mrp products used overseas Mrp are really good. I think that you should do camshafts and valve Springs first.

Exhaust And intake then go for the ecu and tune and motor mounts if not done already so excited to see you next mods !

Nice comparison. I want a Sushpants t-shirt.

i'm defintely subscribing, this is so cool. also, i actually got a corolla dx, ae82, 1984. amazing cars.

Great Video man, I'm looking forward into upgrading my suspension also on my Ae100 corolla, currently I'm getting way to much understeer at our local Autocross events, thinking of getting BC racing coilovers and getting a thicker rear sway bar

amazing video!

Your car looks clean

Stand-alone engine management gets my vote. Also, I want a shushpants t-shirt! :)

I WANT A SUSH PANTS T SHIRT!! Haha, love the vids man, glad to see fx16s are still kicking, also the first upgrade i believe that would be the most beneficial are cams and valve springs, just a thought, keep up the great vids dude!

I swear, every time a video comes out, I end up scouring craigslist listings for a good week or two looking for an FX16 also, I want a Sushpants t-shirt!

Love the videos. I have a 20v in my Westfield (Lotus 7 replica) and am curious to see the power upgrade development for ideas for my car... and I want a sushpants t-shirt.

SUPER WHITE WHALE I don't even remember the last time I've seen that car side note your content is great thanks for the video keep it up

there's a couple [not Google-silly autocorrect] suggestions below regarding the next upgrade, but personally I think I'd do the ECU 1st... you can fine tune the itbs which may or may not yield more hp... and you can fine tune for cams and exhaust later once you get them with the added benefit of being able to share your results with each new mod... dyno verified of course

Exhaust system and wheels and tyres . “I want a dish pants t-shirt.” Love the car

I want a Sushpants t-shirt! Awesome episode man as always! Keep your 82 clean and awesome! I thing for the mod the best will to start with an ECU!

Hi there, I just purchased a ae82 liftback, with the basic 4ac carby engine. I was hoping to put a blue top in it at some stage but for now am doing it up slowly, and watching a few of your videos on your 4age hatch is giving me hope and ideas

Definitely ECU-exhaust-cams and springs. It is also a good idea to upgrade the stock brakes. BTW I want a shushpants t-shirt!!!

Great video as always. Go for a full exhaust. Also....I want a sushpants t-shirt!

nice one. you should do an exhaust upgrade next . cant wait sushsie

Fantastic video, I miss driving my FX so much right now. It's been in the driveway for about a month now while I wait for money to fix it :( I need my fix. “I want a Sushpants t-shirt.”

Exhaust first for good flow. Love from a fellow rolla owner from Australia. I want a sushpants t-shirt!

Corolla looking good! i would go for exhaust next oh and "I want a Sushpants T-shirt."

I'd definitely go exhaust first as it's always the bottleneck for other engine upgrades. Also,​ I want a Sushpants T-shirt!!!!

love the 80s B-movie music you used for this video. Also the only real upgrade you can do for the 4age 20v is turbocharge it. Getting higger cams will be a headache will only gain about 10-15 hp depending on the profile you run. Another downside to camming it is youll have to dump the vvti and the car won’t run nearly as smooth

My intrax springs worked really well on my fx over tokico's. Go for the cam and valve springs. I want a sushpants t-shirt!

Mrp!!! Nice dude

definately exhaust first ,let that engine breaaathh. Also i want a sushpants t shirt

Cams and valves would be awesome to hear! Also I want a sushpants tshirt!!!

A good standalone would definitely make sense for getting the most out of any further mods down the line. A full exhaust system would be a close second though, something subtle as to not overpower the glorious sound of the throttle bodies. Btw, I want a Sushpants t-shirt!

i think that thing needs exhaust work, and i think my ae92 needs those mrp ball joints and rear camber plates for my fortune auto's. also I want a Sushpants T-shirt!

Gosh this is a beautiful car, wish it was selled in SEA, only the sedan version was launched here back then

Great looking AE82! I'm getting BC coilovers for my AE92 soon. I could barely fit 195/50 R15s on mine as well (Had to roll the fenders in the rear) :/. Also "I want a SushPants T-shirt".

Exhaust! Let that engine breaaath!

I want a Sushpants tshirt! Love your videos. I would really like to see an exhaust build video next.

I love this car!!!!

Such a good video man! I want a sushpants t-shirt too!

Love the style of your videos! I want a sushapants T-shirt.. To match my ae82!

OoooOooOOo niice setup, reminds me of my 2002 daihatsu mira avanzato. pretty slow in acceleration but a true go kart for the public road. Would love a t shirt though :)

Damn the FX16 is really coming together. Also, I WANT A SUSHPANTS T-SHIRT!

ECU will set a good base for future mods. Also, I want a Sushpants T shirt!

Cams first, then ECU, then Exhaust. Nice car btw

Exhaust for sure! Also "I wanna sushpants t shirt!"

Now it looks awesome. first upgrade should be ECU.

Exhaust first, then ECU & Valvetrain at the same time to take full advantage of them. Also, I want a Sushpants T-shirt!

I want a Sushpants T-shirt! “Wow...it’s rubbing.” 😂 Hilarious! Your videos are informative and entertaining. I should have subscribed a long time ago. Keep it up!

Best sounding 4ag “i want a sushpants tshirt”

ECU is probably the best for the blacktop :) Oh and I want a Sushpants T-Shirt :)

Cams & Valve Springs! I want a sushpants t-shirt! :)

Do the exhaust first. And hell yes, I want that sushpants tshirt!

My favorite power upgrade is a steering wheel ;) I want a Sushpants t-shirt.

Exhaust and Ecu. Then cams and valves. In the order. No canister exhaust

I think the exhaust system is the best mod to start "I want a sushpants t-shirt"

I want a sushpants tshirt! ECU should be next upgrade, that way you can take full advantage of the eventual exhaust and cams update s

Great vid. Loved it. Do you have the 5 valve. I do not yet. But on my old 300K 4AGE 16V that I bought new. I Ported and polished, (very little porting, those suckers are big already) matched intake with exhaust ports, shaved the head till true. and put it back together. All new valves etc. My off the line power really woke up. Good luck. Love the 4AGE / AE 82 , 86. Wayne.

I say a full exhaust system first and then a standalone! I want a sushpants shirt!

I wanted one of these be back in the day but it cost a little too much for my credit to carry it looks good.

definitely valves and cams.

I want a Sushpants T-shirt. AWESOME VID MATE! My AE82 is very similair setup to yours but BC coilovers and 16v 4AGE Bigport. Wish i could touge battle you. Im your biggest Australian fan.

ecu + cams 💪🏼

Ring up MRP to build you a crazy engine. They are one of the best 4A-GE builders.

You should upgrade the brakes first. Even a standard pad + disc + brake line + brake fluid combo on fresh calipers will be a huge bonus in terms of brake feel and fade resistance. I'd also consider a brake master cylinder brace for added brake feel. Then I'd do the ECU, exhaust and cams, followed by a remap. Oh and I want a Sushpants t-shirt please. :-)

very nice corolla

Exhaust! I want a Sushpants T-shirt

standalone! I want a shushpants t-shirt!

I think an ECU will be the best upgrade. Also I want a Sushpants T-shirt!

I've got to go with the obligatory I want a sushpants t shirt! Also I just love this car and don't mind in the slightest with what upgrade you go with next!

Another great video, I’ll have to see if they make a set for my AE92 coupe. As for power upgrades, I think a 2 1/2 inch catback would be a good start, and maybe you could do a comparison and see which mufflers sound the best? “I want a Sushpants shirt”, and you outta think about making slaps too

Thanks for the videos much help..Also I want a sushpants t shirt...

Nice car

valves and cam first then exhaust . you can do ecu later because corollas can be driven on stock ecu
