I'm looking for 944 N/A power upgrades
Can anyone here recommend a place or places to buy performance products for 944 N/A's? I'm thinking of cams, intake, exhaust and stuff like that.
A friend who is an engine builder is looking for stuff like this and asked me to help him since he's not really a computer friend.
Please don't tell me to buy a 951 instead, it's for building race engines to compete in N/A classes.

Sweanders, what are you doing over here?
There are a couple of SC kits out there for 944's.

If he's trying to compete in an N/A class I think a supercharger would be out of the question. I hate to say it but there isn't much power you can free up naturally without a rebuild.
Maybe if you did the 3.0 swap ($$$$$), or bore the 2.5 a little, 12.5 compression pistons, agressive cam, headwork always helps. A 951 trans can help your times maybe.
I always can use some ideas as well, except I'm on a very tight budget, so it looks like I have to wait a little while.

He asked me if I could try and find some stuff on the net and he specifically said that he needed upgrades for the 944 N/A 2,5 liter engine.
This guy is an experienced engine builder and usually manages to get over 100 hp/liter on the engines he works on. Usually it's 911's. Lotus 4-cylinder ones and Volvo (race/rally car) engines.

Well, it's no secret how to get power from a N/A motor. But if it's intended for a specific racing class in a certain sanctioning body, it's pointless to even research what power is possible until you know what you're allowed to do to the motor.
If you're just trying to get as much as possible, you could max out somewhere near what a stock 951 would make (close to 200 at the wheels) if money was no object.
More typically, the basic I/E SCCA runners are getting low-130's to the wheels on basically stock motors. They are allowed a filter, an exhaust, cat delete, and maybe a header system...but that's about it.
High compression, a ported big valve head and a nice cam would certainly be in order if you want respectable power fro that motor.
However...and I'm sure many here will agree...you don't *need* gobs of HP to make the 944 competetive on the track. Time and time again I hear of N/A 944's hanging with or beating vehicles with considerably more power. This car is all about balance. It can get out of it's own way, has a decent TQ curve, has good roadholding, and excellent handling characteristics.
I think to be competitive on a road course, your money may be better spent on a solid suspension, and there's a number of choices to be made there!
At any rate...expect anywhere from 125 wheel HP (completely stock early 944) all the way up to the 190's wheel HP (completely built with mucho dinero invested, we're talking taking out a 2nd mortgage here). The basic bolt ons should get you between 130 and 140 at the wheels, thereabouts.

how could this not have been suggested already?
Vtech sticker- 10 hp
Nos sticker- 8 hp
Type R sticker-11 hp
Type R badge- 15 hp
most stickers usually have a minumun of a 5 hp gain. You can gain extra by sticking more then one of the same sticker, but you loose a couple hp out of the origional gain of the sticker. so NOS was 8, a second nos would be about 5 or 6. so a total of 13 or 14 HP with two NOS stickers.
You may also try welding a trash can you your exhaust, and add about 150 pounds of ballast's with some sick subs, tv screens, and underglow and 19's yo! It hasn't been proven, but according to many users, the underglow is said to increase HP as well. I'll update you on that when I know. Also, a popular trick to suspension is to cut your springs. this makes the car lower, and if the car is lower, then it handles better, braw.

Seriously, depending on his budget for the engine. I think the real accelleration is removing as much weight as possible. if he gets very picky and removes ANYTHING not necassary, a wire no longer used etc, you can end up ditching more then you thought. and Lightweight as much as possible. Flywheel, crank, etc. Light weight driveshaft. (Boostguy951 has an aluminum one in the works, dunno when he will release it.) Anywho, weight bad. suspension good, extra power from an NA engine, icing on the cake. I want to build an NA race car someday, i think it would be fun, cause it would require more driver skill to do well then just catching up on the straights with your 500HP 951.
