This is my first post and I being think about getting a turbo for my 96 eclipse rs. I was wondering if a fuel pump, super- afc and some 625cc injectors be able to support 15 pounds of boost. The reason I ask is because I was think about buying a hrc stage2, and adding the injectors and the super afc and raising to boost to 15 pounds. Do you think this would work?

Not a chance. A stock 420A won't take 15lbs of boost.

An SAFC doesn't give enough control over the pulsewidth to make your car idle with a 625cc/min injector, either.

What part of Texas ya from, Vic?

Oh sh*t!!! I forget to mention.
My engine died on me 2 weeks ago. So I going to build it, and was think I could install the turbo when it is out of the car. To make it easier. DO you think this homemade stage idea would work.

With a built engine, you can run 15 psi with injectors and and ignition with timing retard.

How about 500cc injectors?
I am from the south. Laredo, Texas

im pretty sure that 440s are the biggest you can do while using a S-AFC

With 8.8:1 compression on forged pistons, you cn run 15psi with no timing retard. I do it daily on my STAR-powered GS.

If you have a fully adjustable fuel pressure regulator and can lower the idle fuel pressure, 550cc/min are possible with an SAFC. You may still idle rich, however.

Is there any other way to the increase the boost to 15 pounds that you know of?

This is the safe way, I wouldn't recommend anything else but some people use thicker headgaskets to increase the boost on stock internals.

cool, thanks everyone for the help.

But, i still confused on one thing. Will the stage 2 hrc kit fuel system, support 15 pounds of boost.
:D I guess what im really asking is there a cheaper way to upgrade to stage 3 without having to buy a stage3 :D

all you should need is bigger injectors and maybe a better FPR

...on my built engine my compression is about the same. From the Low CR pistons and milled head my result is almost 9.5:1 and I need retard for anything above 13lbs. I don't think many people know that porting drops compression as well.

How many points does porting drop the compression down?
