JAPSPECGTUs

Okay heres my setup now let me know
89' TURBO jap-spec. motor/w harnest & ECU was installed in my 89' GTUs.
Boost gage.
FACTORY GTUs: 4.375 locking differential & trans geard to macth, 4 piston calipers,<BR>
16x7 wheels by BBS(polished), aluminum fenders & hood.
AFTERMARKET INSTALED
DieHard Gold battery, front loaded calipers + brake job, tires- f.205/55/16 r.225/50/16, Intrax springs, Tokico Gas struts (f.& r.), Tenzo intake, Greddy Type R blowoff valve, boost controler, 2.5inch Downpipe, Midpipe, Borla stainless steel catback with the sweetest sound not too loud. No air pump, cats, power steering and A/C removed..
CAR CONDITION:Runs 5psi boost and is stronger than my friend's Turbo2 on which he has a HKS intake and complete Apex exhaust, and runing stock boost at 7.5psi
NEEDS: Front mount inercooler & pipeing KIT to be able to run more boost

This is what the Autotrader Ad said when I bought it for 6,000 it has 60k on motor and 113k on the chassis, rides very smooth...

The problems I found with my car when I bought it were a shot T.P.S. and the guy, being as cool as **** as he is sent me a free one, and the Turbo Induct boot is brittled and leaks air.

I need a stronger clutch, the N/A won't hold up under more boost. I am getting a GReddy FMIC, but then I am confused all this air, fuel mixuture ish confuses me, I need to get a different boost controller, this one I have is a manual one you twist. I don't race my car or run it hard with out the IC, I did a couple times when I first got it but I smarted up. What is next? Also I have some questions:

-I am sort of afraid I am gonna blow my motor racing, can the rotary take a substanital amount of street play? -I just wanna rape all these Hondas. Mitsubishis, Toyotas, ect..basically my license plates are gonna say I-4 KLR
-The guy had a time slip from before he did any of the exhuast work at it had a 14.2 as his best. I imagine at least a high 13 at what it is running now?
-What is a good RPM level to dump the clutch from I haven't been able to practice because of the IC thing.
-I have this idea that my car is sort of one-of- a kind because it is a GTUs with a Jspec in it, is that all in my head?
My goal for this car is to dip into the 12's BEFORE a rebuild with a street port and a GReddy or HKS Turbo UPGRADE which I plan to do when I pay it off in two years, is it possible without nitrous?
I was thinking of getting a Single side exhaust, Apexi intake, pulleys, shortshift kit, pop of valve.
Any advice for me, btw I love my car, I love how it vibrates when I rev it up only a few thousand RPMs, I like it also when it takes in a deep breath and makes the domestic ********' heads at my school turn. Even my moms b/f who has a 93 Viper RT/10 with 500 hp(many mods) said my car was "a peppy son of a bitch" Bobby if your reading this...it was worth the 4 hour drive there and back....

yes you are probably the only GTUs turbo. as there were only 1000 or so of them made in the first place.

the stock IC will take 10-12psi with out problems. that of course is asuming you have a turbo II hood with the hole in it? so the IC can get air.

btw, a good rpm, i have a n/a and i dump the cluch at 6500-6800, i never let my car go all the way to redline
and my suggestion (and like i say MY SUGGESTION) dont do nothing to the car, keep it and buy a tII, is the first GTUs turbo i heard in my life.

Tec

the greddy type R bov is to much for your car!!!! it's rated at 20+psi, you not going to need anything more than the type S! I would be suprized if it's working with 5psi.

JAPSPECGTUs

20 Psi really? I was wondering why it is so quiet, however the top of the bov is removed and it is free flowing only one pressure release valve opens(is there two?). I will post pics when I get a lil more time busy at this moment, I don't have a TII hood that is why I am getting a FMIC, plus the FMIC is better anyhow right? Anyone live in St. Louis?

Scott 89t2

ah I had a good guess definatly try to refine from boosting till you get one.

MtnRacer

Out of curiosity, have you weighed your car? How much does a GTUs weigh with the turbo motor(I guess it looks like you haven't installed the TII drive train, but if you did, let us know too!). My project is very similar to yours, so I'm interested. Thanks!

You're going to ruin that GTUs spec tranny if you keep on abusing it at the dragstrip.

rx7_ragtop

Just what I was going to say. Put in a TII tranny when you swap the clutch. Use the TII driveshaft, and have the holes in the TII driveshaft flange re-drilled to mate up with the holes in the NA differential. You'll need a TII flywheel, clutch, PP, clutch slave cylinder, and starter. You will also need to make some "extensions" for the wiring harness to mate up to the TII tranny. You WILL destroy the NA tranny, although the diff is probably strong enough.

Okay...so TII Flywheel, clutch slave clynder and starter, like OEM parts would cost? The clutch and pp I am getting a Stree/Strip one so I know the price for that. I then need to buy a T II driveshaft, and a transmission, ****! How much is that gonna cost??? Labor is gonna be a son of a bitch.......So then with a different tranny wouldn't I need a diff tach or do they still run to 8000 on the T II? Ahh you guys gotta help me b4 I go and buy stuff I don't need.

JAPSPECGTUs

Okay I have found some used trannies for 300, will they be doable? Driveshafts are 270 at Mazdatrix, where can I get the clutch cylinder, would used be okay. Those extensions on the harness what do u mean? The pics I tried to upload are too big in filesize so I will convert them to a smaller file size l8er.
