Most hp and torque you can pull out of a 2.0?, And keep 87 octain and reliability... Options

[DerekKim]

Exactly what the subject says. I'm trying to see how much I can pull out of this 110(correct?) hp car and keep her on 87 and reliable. A friend of mine suggested cams headers and port can get me about 150hp. Doable? 150 would be good for me to get use to the car. Anyone know of companies where I can pick this stuff up or other 911 components or something I can swap in? Any help is appreciated.

Thanks,
Derek

you friend reads too many "ricer" mag's (IMG:style_emoticons/default/smile.gif)

the Type IV does not respond too well to the normal "bolt-on" items that most other motors do....if you do some searching here, you'll see how Jake Raby (Type IV guru) will always say it's "all in the combination".........from what I've read here, the exhaust ports are terrible on our /4 motors.....the most common mistake people do is do a port job to increase the intake, which on the /4 motors are not a problem....it's easy to get the air in, it's much harder to get the air out.....of course you might say "fine, I'll just do some exhaust work"

well, the problem with that is that the stock heads do not tend to be a good starting point for this either...the solution is to use brand new square port heads and re-work those (more money)

also from what I've read, the cams available for the /4 motors are not the best designed, the best ones are available from Jake who has done extensive testing on them....not sure if he sells them seperately or not...

another thing to remember, the Type IV is different enough from the Type I's that you cannot compare the 2 when it comes to modifications
