here's some info on doing some "tests". 2 days ago I installed a full 3" racingbeat, fcd, and greddy P/H EGT into my 89. with a K&N cone, crane hi-6 ign, and rewired stock fuel pump already. also a manual boost controler turned all the way to "-" (so I was running 5psi before exhaust as stock controler was bypassed)

with exhaust and k&N cone I got 5psi in first, 8 in 2nd, and barely hit 10 in 3rd at about 5500 but then it droped back to 8 by 6000. in forth on the highway I slowly creeped to 11psi then let off as I didn't want to go over 10. even here I only hit about 800C (1500F) so the fuel was ok.

with exhuast and stock air box.

5psi in first, about 7 in 2nd, 8 or 9 in 3rd. and barly hit 10 before droping while WOT up a big hill in 4th at 5000 or so. once again right at 800C so doing just fine fuel wise.

so on a 89+ turbo with a stock airbox the racingbeat exhaust seems to be ok fuel wise and it stays under 10psi with the stock controler disabled.

now to play with the controler to get 8-9 psi in every gear and lower in the rpm range instead of slowly creeping from 5-9 over the rpm range.

oh and the exhuast sounds so SWEET!!

So is it a completley different beast??

 

o yeah!!

you will probably have worse creeping problems with yours though.

thats low miles!

 

Thats what I am told, but thats not a problem because the wastegate will be getting ported with the exhaust install---also, did you have any difficulty installing the RB?

 

I didn't do it. but the guy who did had some problems. if the precat has never been taken off it's a pain in the ***. there is a heat shied with like 8 bolts you have to take off and they are all hard to get to. then under that there is a metal "clip" thing that wraps around all 3 precat nuts so they won't come loose over time.

 

Damn, sounds like this one could be a PITA--wish me luck...

 

Hey Scott. We have almost the same set up. I have the RB full turbo exhaust, MSD 6A, HKS FCON, and HKS filter, no boost controller. Before I was running only the exhaust, MSD, FCON with stock filter and I got 8 psi in every gear no creep at all and my EGT reading is about 1300 F. With the exhaust MSD, FCON and HKS filter it reached 9 psi in first, 10 in second, but creep all the way too 14-15 from 3rd to 5th.... I was afraid to step on gas. I am local to you so maybe we can exchange some openions.

 

what year is yours?

is it black with a "redzone" or something like that sticker above turbo II?

 

Hey guys!..i will have the same setup on my 87TII. I also purchased an FCON and just wondering if the FCON is a great buy!..I have
RB full turbo back system
HKS intake
HKS FCON
FCD
FMIC

will get...
Compressor upgrade
gauges

 

Yes my car is black 88 TII with the redzone sticker on the side.
Hey fcturbo2 we have almost the same set up. I am wondering how many psi of boost are you running and what FMIC is yours.
