Ok guys I'm looking for a little advise here:

The car as it stands right now is this:

Rebuilt 1990 TurboII engine w/ Street Port (2,500 miles on it)
Cone Filter
HKS Bov
Turbo Timer
17x7 Wheels on front and back
HKS Exhaust coming next week

Now I am thinking of doing this:
Stage 3 Turbo Upgrade from http://www.lourdsmusic.com/bnrsupercars/turbo8991.htm

Now if I do this with my exhaust what will I need to run nicely?

I was wondering if I should get bigger injectors (720's) or get secondaries?

Should I get a Apexi Super AFC , or is it needed with bigger injectors/secondaries.

Also I know I will need a FCD, do you think a Boost Controller will be needed?

What is everyone's suggestion? Any particular order to do this stuff in? Exhaust is coming, so put that into account

 

The best way of course is getting the haltech & fuel computer from the start. The lest costly way is to upgrade your fuel system & turbo but keep the boost low until you can afford a complete engine management system. Some even go carbed with no ECU.

 

That is one nice *** car you have man i still cant believe you got a s5 tii. Wish i had a bud that would ssell me one.

 

Hehe I know knight1976

I was at the right place at the right time. Friend is in desperate need of money so I offer him $1000 cash for his 1990 rx7 Tii!

If only I could be that way with the women...seems Im always in the right place at the wrong time.

 

I'm guessing the HKS exhuast is only the cat back. so you still need a down pipe and mid pipe. get an FCD. 720 secondarys. S-afc. and bigger fuel pump.

if you want the bigger turbo, You will also want/need a FMIC and bigger Rad. maybe also 720 primarys.

if you get it tuned right using a wide band o2. should be good for 300RWHP

 

Scott:

Thanks so much for your reply.

I already have a upgraded Fuel pump on the way. After that I will go get a down and mid pipe and FCD.

From there I will get 720 secondaries, and a S-afc and boost controller then upgrade the turbo because it seems that the FMIC will be pretty pricey.

Are there any cheaper alternative's to FMIC? I hear that FMIC can get bad turbo lag. From what I understand the reason for me getting a FMIC is that when I upgrade my turbo I will need it Front Mount intercooled because it will be pushing more air which a Top mount intercooler can't keep up with.

So looking at this I wonder if there is anyway for me to engineer a way to cool the front mount better. What do you guys think?

 

Actually the stock intercooler FLOWS ok, it's just in a bad location and doesn't have enough surface area. BDC built a water tank around his stock intercooler and used it to do a air-to-water with an "icewater" fill tank, an electric water pump, and a civic radiator. Complex, but it was good for 425 to the wheels.
