Re: what car/engine?
Check my sig, I've been talking to some 10v guys who say 300 bhp is realistic with a new snail, bigger DP , and a full exhaust, plus some extra boost. What are realistic numbers for modded 10v turbos?
The guys at 2bennett say 300bhp is what i should expect for the extra mods I'm planning.

Re: what sig? no sig, no pics in your account............
Hmm thats strange, all my post's in this thread read, "88 5KCST Intended Acceleration Stage 1- H@R Springs w Bilsteins SS-ATE slotted rotors- 222 bhp"
Weird,
I am sticking with CIS for now, as I'm told 300bhp is pretty much the limit for it and my car will keep me entertained with 300bhp (for a while at least). Am I missing something on my quest for 300bhp?
Will the K24 give me as much peak HP as the RS2?
TIA

300hp if you know exactly what you are doing with it, otherwise you'll only be able to get around 250hp before modifying the CIS system to allow proper fueling for the added boost.
Not a good idea for someone looking for bolt-ons to reach 300hp. EFI would be much smarter, trying to get CIS to that level w/out knowing what you are doing is a death sentence for your engine IMO.

Well I didn't plan on tuning jack, I was going to drop my car off at 2bennett and let them find the 300bhp, or close to it. They seem to think that a K24 will support 300bhp on the CIS with a cam, downpipe and full exhaust, when properly tuned by them.
I should be dropping it off to them in the next month or two, then I will dyno it and post the graph.
I hope for at least 280bhp.

What turbo are you replacing?
The k26 that originally came with that car is bigger than a k24 - meaning it will have more top end, which is what you are talking about when you say "300hp". As birdman and koop have said, 300 with CIS will be difficult to do, and even harder with a k24 rather than with a k26.
The main advantage a k24 has over a k26 is a lower boost threshold (what most people mistakenly refer to as lag), meaning it spools up at a lower RPM. It will have less juice on the top end, however. It may have less lag, too (the delay between stomping your foot and getting boost when you are already above the boost threshold), but that difference isn't likely to be as big as the difference in boost threshold.
Spend that money on EFI if you want 300 reliable hp.

Regarding the RS2.
The RS2 is like a bigger K26 (as specified by Porsche, who used a K26 on the 944 turbo) with higher boost threshold and more lag, but more top end grunt as well. With the starting point of a K26, the K24 and RS2 are in opposite directions.
CIS would have an even harder time trying to take advantage of the RS2's strengths.
