Lart... is it true you have parted dozens of 944s ? i wonder how many of the original 944 fleet are still running, at least on the weekends or at track events.
in any case, the only car i will be turbocharging anytime soon will be a Cayman as my second driver once my 968 is finished... my father is busy shopping for a Cayman on ebay... as far as the 944 turbo goes... you all know best.

Mix and match your items if you want. If your wallet is fairly thick and you truly want the best...Vitesse is second to none. You could get a full Vitesse stage 2 or 3 car, run a worked N/A big valve head, CEP header and cross over...and 350 would be no problem. I've ridden in a 340-350whp Vitesse Stage 2 car. Very quick spooling car. No internal engine mods and around 17lbs of boost IIRC.
I'll be running a full Vitesse Stage 3 car. That's the turbo, MAF, piggyback, V-Flex and hopefully wasted spark too. The Vitesse stuff pulls a premimum for sure, but I can vouch that it's worth every damn cent.
"It costs money to go fast, how fast do you want to go?"...very true statement lol

a one vendor kit is perhaps the best option if you like that new part smell ... what ever that is .and realy want to part with 4 grand in a moment.
But if one was to get that pile of stuff from Ski then spend 2 grand on what ever they would be miles ahead of the "play it safe " one vendor guy ...
Good vendors such as Mike and John still support there customers if they have spent 4 grand on a kit or 200 on a single component .

As many have stated already, concentrate at the area under the power curve instead of a peak number. There are setups that give you peak numbers with terrible area under the curve (too much lag). There are setups that spoolup quickly, but cannot flow enough up top. To get something that spools up quickly and flows plenty to support plenty of HP up top is what you want (at least that's what I prefer and sell).
A fast 951 will have a different power curve than a dyno queen, even though the dyno queen might make higher peak HP number. You must look at it as a compete system, Turbo and engine management. Performance and reliability are both important! Reliability is very complex, you need the correct AFR and ignition, no matter what boost you run. You also need a system that will catch a problem and handle it properly to try and save your engine. Your engine management must do more than your basic fuel and ignition!
Of course I must say it: take a look at the V-FLEX software. You gain performance and if it saves your engine one single time, it pays for itself.

Reliable 350rwhp are possible with 91 CA pump gas. Here is a video of my dyno, drove my car for 3 years like there was no tomorrow.
what I had in the car:
T04e
55# injectors
AFPR
Power Perfect
APE Chips
LR MAF
38mm Tial
SFR Intercooler Pipes
SFR Stage II headers
SFR X-Over pipe
SFR Downpipe
SFR Test Pipe

well, I actually went up to 23psi and technically it was 91 octane, but I added 10% xylene.
By the way, I don't recommend building a car from bits from here and there, if I had to do it again I will go with one vendor and my choice will be Vittesse.

That is an excellent question.
I love my car, but I've spent thousands of dollars on mods (full Garrett dbb turbo, custom 3" exhaust, Tial 44mm wg, ebc, 52# injectors, big fuel pump, Vitesse MAF, etc etc), and I'm putting down 325 rwhp at 17psi on 94 octane pump gas. I drove my buddies 951 on the track last season, his is equally well-prepared as mine w.r.t. suspension mods, but he's "only" running a chipped K26/8 and around 270 rwhp. His car is not quite as fast as mine, but it's still damn fast and a lot of fun on the track. Driving his car definitely made me scratch my head and wonder about the $$$ I've spent on mine...

What power numbers are owners seeing with a KKK K27/6 or K27/8? These turbos are cheap and should be simple to install. If 350whp is a lofty goal perhaps I should shoot for a strong 300+whp with a cheaper turbo?

Good real world point of view. What does the extra power really mean at the end of the day ![typing](https://rennlist.com/forums/graemlins/yltype.gif)

I have to laugh at this post or cry when I think about my own car and the money I've spent. ![hiha](https://rennlist.com/forums/graemlins/roflmao.gif)
Once you start modifying these cars for more hp just plan on opening up your wallet because the modifications seem to never stop. Look a Georges car. Last I heard he was still spending $$$ on it.
These cars are just so addicting and fun to drive!!
