My 86.5 1JZ --> 1.5JZ Swap

[Bigzavs]

This all started out about 3 months ago being tired of how laggy my GT72 was on my 1JZ, i was hitting boost around 4800-5000, and wasnt liking it too much. So i sourced out a 2J bottom end locally, tore it down, had it decked and honed and also sourced out a set of 10k mile TT rods and pistons (block is GE).

Also was tired of the harness/ecu problems i was having with the 1J equipment. So thanks to my brother who is located in Yokosuka, Japan i was able to get an Aristo Harness and Blitz Access Ecu. I have yet to run a stock ecu in my car :icon_bigg.

car swap is being performed on

1JZ before going away, just had gotten everything powercoated by RBCoating

pics during motor pull

then i got some really bad new on the build, my turbo was shot, horrible lateral shaft play, i loved that turbo, had a good amount of money into it between powercoating, ceramic coating, and the anti-surge.

so that really put a hamper on the car, also kept it from making it to 2K9, couldnt source out a turbo that would match up within the week that we had to finish and go to 2K9 in.

 

[Bigzavs]

So i decided to go a lil bigger after 2K9 ended, also decided to take my time after seeing 3 friends blow their motors at 2K9.

Got a T88-34D with hardly any use on it from a Local guy. He made 902whp on it and trapped 10.001 @ 147mph, then took it off and went bigger.

Had a few problems with it tho

1. oil lines didnt fit
2. DP had wrong flange and wasnt long enough.

friends spare oil drain fit it though, and dynosaur performance had the right oil line in stock for me.

Also ran across a deal from Ken that i couldnt pass up on an OS Giken Triple Plate clutch, so i pulled off my OSG super single and put on the triple plate.

pic of the motor back together and going back in, thats me on the cowl, i was tired and ready for it to get back in.

Motor back in with new turbo mocked up

fast forward about a week. most of the motor is assembled with the old i/c piping setup

heres with the changed/new i/c piping routing.

time for exhaust/dp. decided if im gonna make my own exhaust and dp again, might as well go big, 4" all the way.

exhaust not finished in the pic, has a 2nd v-band downstream and flex pipe.

also got the harness adapted for the car, was able to get rid of a shit ton of wiring and connectors in the process

and she cranked right up (well almost right up)

[Bigzavs]

Fast forward to today, talked with OS Giken about the issues im having with the clutch, and it turns out i have the wrong sized release sleeve bearing. I have the single/twin plate one. and it does not work on the triple, as ive found out. cant get the bastard into gear. so i started to take the motor down to pull it to fix it this coming weekend.

and heres the interior re-assembled

thats it for today, probably take it down more tomorrow just so i can pull it easily come saturday.

super sweet ride dude.. looks nice.

 

[XofXtimeX]

Looks great Ben! Cant wait to come back home and see this setup in person.

That 72 pulled really strongly so I can't imagine what this will do with supporting fuel...

Looking good ben. One question though. Why do you always pull the motor to take the trans out. Why not do it with in the car. Just asking in case you know somthing i dont.

 

[Bigzavs]

with the design of the triple, and clearance issues on the trans, its easier to just pull the motor and work on it

 

[alloyguitar]

Nice build!

...and I'd pull the motor, too, if I had clutch issues. Swapping ANY clutch in a supra with the motor still in is not fun. Ever.

[Bigzavs]

thanks

the 268s ive been running are out and about to go into another local car, just waiting on the new cams to get here from Zazzn, gotta get them to the machine shop asap.

motor is ready to pull out tomorrow, and the sleave bearing is on order and being shipped out monday from RHDJapan, due to Golden week over in japan, they were closed till yesterday.

 

[s383mmber1]

I loveee your car! Absoulutly stunning:love: Sorry to hear about that turbo, i reallly wanted it too, but it looks like that T88 will do it for yah

Good work

 

[Bigzavs]

thanks dude, sorry the turbo didnt work for ya, still cant believe it went out that bad! in fact, joe at PHR hadnt heard of the GT72 going out that bad with so little use

 

[Bigzavs]

becoming an all too familiar site for my car

new sleeve bearing is on order from OS Giken, cams got here from Zazzn friday. so itll be going back in once the new bearing gets here

car is back up and running, had an issue with a sticking injector making the car run on 5 cylinders, but its fixed now, but still having the charging issue ive been fighting for a while now, pissing me off

clutch works beautifully now, fricking grabs like crazy, stalled it out a few times now

 

[slowmedown]

I really like your MKIII. Sounds great with the 4 in exhaust. Makes me want to get another one someday

 

[bmk3]

looks nice love ur lip and rims cant wait to see this in person

 

[integra08]

Clean..how much hp do you make now?

 

[Bigzavs]

if i do 450whp ill be happy

if i break 500+ on pump ill be ecstatic

 

[Turbo Drifter]

if i do 450whp ill be happy

if i break 500+ on pump ill be ecstatic

That should not be a problem at all, on my T67 untuned at 1bar I was at 460whp 2jz but should not make much difference.

Car looks great, very similar to mine.
