944 upgrades
Hey guys,
I'm in the process of rebuilding my 944t engine. I just got it torn down and everything looks reasonable. My question is what could I do to add hp without spending a ton of money. It has a mass airflow/chip kit now, looking for a little more. thanks, JimV

Good luck though!

You are using the word rebuild...that emplies nothing cheap 
And one man's cheap is another man's Porsche.
FPR
Injectors
Exhaust
Turbo
Those are just some ideas.

Wastegate would be a nice addition, the stock one is most likely shot as most are and rolls the boost on slow. A good flowing exhaust will help too. Also an electronic boost controller. You have already cleaned up the intake with the MAF. Next would be turbo. I have a custom free flowing intake, a 3 inch exhaust and a custom fitted Audi dual port wastegate. The car performs quite well, boost comes on a bit quicker than stock as well. Good luck

shmucklebuckle thanks! It looks like theres a lot of talent on this board
Peckster, I'm rebuilding for a couple of reasons. It's a high milage car. I had the head off a couple of years ago and saw some mild scoring in the bores. The leakdown was fair but the biggest problem is when I chasis dynoed I noticed oil spewing out of everywhere plus I have a problem taking out cam housing gaskets. I vented the cam housing and bandaded the problem. Im' guessing the rings are leaking causing blowby
Joseph mitro, I did mildly port the head although there's not much you can do in the exhaust side due the the rock hard ports. Is that an insert or a coating in the exhaust port? Is there anyway around it? Port and recoat?
Porsche-o-phile, At first I was thinking around 400hp. After I got the motor out and realized what a project it was I lowered my sites. What a pain. I don't have a lot of time/money maintaining

you want 400 at the wheels? talk to john vitesse... Fast951 on rennlist, he'll sell you his stage 3 for about 3500 bucks... of course you still have to do injectors etc.... or you can go your own route, wg, turbo, etc etc...
