 SR86 "How to" Reply  Edit


So I have had my current AE86 for prob about 3 years now... maybe longer... I've had 17 of them total... I finally decided to step it up... Last drift event i went to with the 20v was the last straw for me... I needed more power, Mr. John at JSP Fab had the answer. His mount kit for the SR20 is great.

In this thread I will provide the information needed to deal with the problems/issues involved with putting the sr20det in the AE86

First you need one of these

and for the swap i obtained a running and driving S14 with the sr in it and parted it out and got the parts i needed off of it

sorry 20v fans but goodbye to this

E-Brake / Shifter Collision issue has been fixed... cut the handle down, drilled out the pin that holds the lock, shortened the rod and re-threaded it, then welded the pin back in place that holds the lock in the handle

trans tunnel has been cut for shifter, dont worry all removed metal was saved so it could be welded back in later if need be...

front K-Member has been dropped for tunnel clearance, im really not fond of this but evidently there have been no negative side effects from it on the AE2000

I could not find it in myself to use the OEM Nissan trans mount, I got the PEAK Performance unrethane trans mount, it is very good quality , notice i had to trim the bottom corners down for it to work with the SR86 trans mount

stainless braided and A/N fittings for the turbo, mounts are installed, and yes that compressor housing does say HKS

also for those who know me would have already guessed that i've had my hands in the wiring harness... it was hideous... but i fixed it as best as i could without cutting any wires...

engine in the car... painted the valve cover so it doesnt look so nasty


spec stage 3 clutch/flywheel

a pic of the Veilside chip

has to move the shifter bezel back and i cut the front of the center console down so it sits in the original location... these pics are with it in 4th gear and not hitting the e-brake. sorry for the darkness... bad lighting in the car at night in the shop


so the PEAK performance transmission mount was questionable if it would work since the mount kit was made using the OEM nissan trans mount but it worked out perfect, not problems with it at all

i reused the throttle cable from the s14

i was told the clutch slave line would have to be a custom deal... the ss line from the s14 worked

i am using the koyo radiator from the rolla... gotta make the upper line but i cut the lower sr hose and it worked fine... for the upper hose i ordered 2 90 degree elbows and a stick of aluminum pipe


so the sr has a electric speedo... and the rolla has a cable speedo... problem solved... mechanical speedo from a 280z... the sr doesnt need a speedo signal... but the rolla cluster does send an electronic signal if i need to hook it up


the turbo elbow pipe was reused from the 240... and it is a hackjob... here is a look for you to poke fun at... lol

got the elbow pipe bolted on... also just for shits and giggles test fitted the 240 megan downpipe... it lined right up with my existing exhaust, which is the same as the stock exhaust just bigger...
ground clearance doesnt look to be an issue either... acutally fits better than any of the headers i have ever seen for the ae86's... here is what it looks like




installed a 90 degree fitting so that i could run the factory AE86 oil pressure sensor and also can wire up the nissan one to a warning light later if i want, the main reason this was done was because the toyota sensor was too big and too close to the oil filter to fit...

interior is done... everything is in except seats, glove box, and pass kick panel... not putting that stuff back ion til i'm done with the wiring... put a new dash in it that was in better condition, put my momo wheel out of my ek civic in it, the civic hub bolted right up but doesnt cancel the blinkers, and installed the canandian twin cam kouki cluster, the european, australian, and canadian model gauges are plug and play for the US models unlike the JDM clusters which have to be wired in



I used a dakota digital tach adapter and the tach works perfect with the SR20 ignition system

intercooler is mounted and piping is welded... also meter and filter are installed... still have to buy the T3 radiator cooling plate to cover the intercooler when the hood is popped



toyota coolant temp sensor drilled and tapped in the lower water kneck, since it was so close to the nissan sensor i used the wire from the sr harness

Im sure you guys can figure out wiring, here is a peek at mine

Here is what it looks like in there and finished, I have to get my driveshaft made now and thats it

motor mounts were from http://www.jspfab.com his name on here is Mr John

for the wiring i cut the vehicle side plug from the dash of the s14 donor car and used an sr5 firewall harness for the guages, that way there is as little splicing into the my cars dash harness as possible and there is not work done to the sr20 engine harness so later if something were to happen i still have a completely wired plug and play s14 sr20 swap

Mind explaining what the 5 links for the Supra rear end do/does for you and your car?

Also what the camber plates are for if you would mind explaining that too .

Tried googling around but it was just kind of confusing.

Thanks for enlightening someone without this knowledge

supra rear end is a 7.5" rear end vs the 6" corolla rear.... much larger handles more power.... the supra rear end does not direct bolt on under the corolla, but Technotoytuning sells the custom 5 links that make it bolt under...

the camber plates are to correct the difference from left to right... my car has been wrecked and my passenger side is .2 degrees off, these will allow me to correct the problem

Sup man! great work, just wondering how you have your alternator wired up. My battery wont hold charge for more than a day. The alt. has a wire running to a relay>to the harness> then another wire running to the positive terminal of the battery. Is there a better way to do this where it'll get the correct amount of voltage?

the small wire goes to the factory charge light wire of the corolla and the other wire goes to the factory ignition wire on the corolla... the third wire on the corolla is not used, the nissan alternator monitors voltage from the positive charge wire...

the wires on my nissan harness were not the same as in the pic below but the pic below is to show you which one is which... bot of my wires were small.... the pin with the small wire in the pic below is to the charge light...

i did not use any relays, i simply extended my existing wires to meet up to my harness i made for the sr20 alternator

Do T3 offer Mk1 supra 7.5 inch rear end and T3 custom 5 links for the supra rear end?? how much did it cost you?
My 86 rear end is going to die soon because of Altezza power, and I need to save some $$ for a good rear end that can take altezza power daily

hachiboy--- why would you put your battery in the trunk??? the sr20 is already a good bit lighter than the 4ag... keeping the battery in the front seems to be the best choice here as my car already sits up higher in the front with it still under the hood...

have you corner balanced your car or something??? let me know im interested in the reasoning

Ha! i noticed the diff in the of the sr and 4ag, steering feels different, i dont like it, but i still have to mess wit the front suspension a little. I havent corner balanced it yet, The only reason it's in the back is because i have a top mount (turbo) setup and ran the intercooler piping where the battery used to be. I also dont like having that heavy battery in the back but i'll get an 11 pounder soon. . .

I dont get why your car sits up higher in the front , jus cuzza the weight? are you on stock suspension or coilovers???

Here's sum pix of my setup, just kept it simple, I also used the JSP mounts, gotta one piece aluminum driveshaft, everything else is pretty stock except for the Turbo, exhaust piping and all that. Still need to shave off the lettering from the valve cover and spray the intercooler black (I always see the cops looking right dead center at the intercooler and then dawg me but they dont bother, they just keep goin) and recirc the external wastegate (sounds like a damn jet coming down the street) i love it but LAPD would love to impound it!!! havent gotten gauges yet but my plan is to have the interior look stock with everything hidden cuz of all the haters out here, they see one gauge or something shiny and they bust your window! Gotta get the tach adapter that you have so i dont have to put a huge aftermarket one, a supra rearend eventually and just minor stuff, But other than that, it runs pretty strong the way it is, way rad motor for this light car= Too much fun!

I have the same setup for my turbo for my sr86...My battery is located in the back as well...Im running a type s blow off valve too, but mine is whistling way too much...I think it is going bad...Does your one piece driveshaft cause a lot of vibration? I am running a custom 2 piece...

Ey Mike, what kinda turbo are you running? i have the T28 from the S15, simple and responsive deal! Are you having any charging problems with your setup? did you use the bmw cables or something else? I would really like to know cuz i dont know whats goin on with mine, maybe bad ground, i did have one busted fusible link on the fusible link box on the pos. terminal i dont know if that has something to do with it. Or maybe the alternator didnt have enuff amps to charge the batt. i was using the one from my M30.

Yea my blow off is a CXracing unit, same exact as the greddy type s, but i have a whooshing sound, i have it on soft, but when i screw it down to hard,it'll have a mad super loud whistle, i mean loud. I have an aluminum 1 piece driveshaft and it doesnt vibrate at all dude, and it crazy light. As for the stand alone, i have no idear yet, i gotta ask around to see who recommends what. . .

Yea i had to make a custom manifold because the turbo im using, needed a different flange to mate with the turbo. Yea i used a gasket, i know some people use high temp sealant but i dont know how that holds up at times, its just best to take it all apart and get some gaskets between there, i just recently blew the gasket on my wastegate and i thought it was a crack in the manifold, but went under the car and saw a nice chunk of the gasket missing. Just make sure you inspect everything thoroughly.
