[Sileighty_85]

Went for a short Drive, No vids yet until I get the BOV welded on.

nice to see it live!!

[Sileighty_85]

Indeed

Got the BOV welded on and damn she rolls out at .5 bar cant wait to up it to .9 bar

I just found an sr5 shell for cheap, and was wondering if you had any pointers as far as wiring. I also would like to keep the corolla gauges and use a converter.

[Sileighty_85]

ummmm, There are a few diagrams you can use.

Its ridiculous how easy it is if you know the SR harness pretty well.
I did mine in 1 afternoon



AS for the cluster, it seems you would need a Signal converter for the Tach and a an Older Z car VSS not sure which one

[s13Kurt]

^ Thanks alot! How much do you think you have in the swap not counting the shell or motor set. Trying to do this correctly on a skimp budget. Already have the motor set and picking up the car for 400. I have a friend that will let me copy his mounts so I just need metal for them. Wiring is free and drive shaft I can get on the hookup. Still need a diff and have to get a fuel cell because of the carb tank also.

You pretty much have it covered, nothing really special needed other than the Mount kit and driveshaft.

Power steering is an issue unless you have a manual rack

Why is it an issue?

[Sileighty_85]

well you'd have to make some custom lines using the SR power steering pump, if you wanted power steering

I joined this forum to gain info on doing my own SR86 project, and have found it to be by far the most informative of about a dozen I have since frequented. Thank you to the many DIYers that make this possible. That being said, I would like to post some info that I learned in doing my swap that might not be mentioned here. It is likely irrelevant to most anyone not doing this swap, but I include it because it either very difficult to find on the web, or because I figured it out through trial and error. When I decide to do my own build thread, I will move this information there and link to it, but for now:

The exhaust is a very tight fit, especially with the turbo in the stock position and power steering. I can appreciate all of the suggestions from other on here regarding a workaround, but if you were to look at it you'd say "OOOhhhhh!" And then, " Damn, dude, how ARE you gonna make that happen?" Best suggestion is to use an aftermarket S13 elbow and then use the ol" "cut-and-weld-in-a-piece-of-pipe" trick, or just beat a big dent in it. Bottom line is that, even with a little restriction here, the car is still going to scoot like a raped ape.

I knew that my future plans included a T28 or T30, so I used a top mount manifold and just welded a t25 flange to it. Custom DIY Teflon lines and fittings from Frozenboost.com. Downpipe was tricky, but I've got 3" all the way past the steering shaft. Easiest thing to do is to buy the t25 to 3" v-band adapter and weld an elbow onto it, whether you go top mount or not. Manual steering rack helps a LOT. Manual rack from an AW11 MR2 works, and they are easy to find. The writeup is on club4ag if anyone else is interested. I'll post pics of my 'finished' project when I have a chance.

The wiring is exactly as shown in the diagram, very simple. I mounted my fuel pump relay in the trunk (near the battery), and used another relay in the front for switched accessories like fans and gauges and whatnot. For battery relocation , I suggest a 120A circuit breaker mounted in the trunk. Also provides a binding post for power distribution in the rear of the vehicle.

EvoVIII FMIC fits great. Cold side S13 FMIC piping fits pretty good, just trimmed 6" off of the rear of the lower piping. For the radiator hose, I found a 1.25" OEM hose with some good 90deg bends. Then we used a section of galvanized chain link top rail (yes, fencing) for the center section of the pipe. You could easily weld a bung to it for a temp sensor. We put a 10deg bend in it to allow it to clear the electric radiator fan.

Some Nissan Hardbody pickups had FS5W71(x) transmission with a shorter tailshaft section. Swap the KA bellhousing for the SR bellhousing and the shifter hole lines up almost perfectly. Also, the truck shifter (and extension housing) has a shorter throw than the S13/S14 transmission due to having a longer spindle below the pivot ball. I didn't want to use the long a$$ truck shifter, so I made a hybrid out of the two nissan shifters. I compared the stock SR20 shifter to the stock AE86 shifter, and they are identical. AE86 short throw shifter on eBay comes with a different extension housing that allows them to utilize a longer spindle, and I'll be damned if it doesn't appear to be exactly what I ended up with after several hours of cutting, grinding, and welding.

I find that the 4.3:1 final drive in the AE86 GTS rear end is a bit limiting, even on the street, but I've got a KAAZ 2-way LSD in mine and don't want to spend a bunch more money right now on a custom rearend. When I do (~6-12mos), I will go with a Mopar 8.75" rear and a 3.8x gear. Some Cressida wagons had a 7.5 solid rear axle, and of course there's always the MKI Supra rearend. The AE86 speedometer will still not be accurate, regardless of whether you use the S13 cluster or the 280z speedo sender unless you change the speedo drive gear for a 4.3 final drive. Just buy a GPS and use that for speed readings. Or get a smartphone app. It's much easier.

Very nice budget writeup. Keep up the good work.

I'll try to get some this weekend, been sick and weathers been shitty

[EazyS13]

i feel yaa weather been sucky here as well

[punxva]

Owning a 86 myself and doing a VQ motor swap I cant see how we went so long without doing awesome motor swaps in our chassis for the same cost as 140hp 4AG. Props for doing this swap yourself and making it reliable, good work!

Thanks


Little work

Got in my Spare 3rd member and swapped in the TRD Diff.

[Sileighty_85]

Thanks, Off topic is pretty much in the dark.

just got in my adjustable T3 Power Steering Knuckles for more angle. Holy Shit they are beefy.


Also Ordered Stance Coil overs last week so hopefully they will be in this week.

[meme2105]

very nice build.... you got me motivated to go out and do work on my car....nicely done sir

[Sileighty_85]

Thanks, Glad I can help haha

Just got these in!! BALLER!!

[cgtdream]

Great thread man...would say keep up the good work but it looks like you got things covered...in other news, i remmeber you from oki....for some reason i got pics of your car on my photobucket...

[Sileighty_85]

Thanks,

Haha Nice I miss that car, Just wish the PO didnt rattle can the car.

[Pinggg]

+1 for Stance coils!

[blitzkrgCT9A]

sick ass build!!!!

subscribed!

[Sileighty_85]

Thanks Guys, I got the Rear setup installed and Feels soo much better

hopefully able to instal the front sometime this week

when I was doing the rear I noticed how bad the rear axle twist from being lowered so gonna have to probably get the 4 link setup as well :/

[Sileighty_85]

Got the fronts installed.

Chassis handles sooo much better now

[EazyS13]

wish i could "stance" lol

[Sileighty_85]

Ordered a rebuild kit for the the Hachi's rear axle and front wheel bearings and Ordered a Beefy ass solid Pinion Spacer from Weir Performance. 3X stronger than OEM

[Sileighty_85]

Still waiting on the diff to get shimmed. :/

Also sent my Hoshino Rim off to get repaired




I must say this is the Most ive ever been impressed by a shops work.
Thing is beautiful. Normally they would clean/polish/repaint the rims but i told him not to since it would make the other 3 look like shit haha





Shop's name was Rim Spec in TX
