Valves

[J.McDonald Knives]

I plan to do a valve job in a few months when I get the money and was wondering what yall recommend for replacement valves that will hold up to the extra HP and TQ. I already plan to get new springs and such.

[Sarra]

The actual valves are pretty strong stock. STi, WRX, and NA valves are all different lengths, so they aren't interchangeable.

[J.McDonald Knives]

What about aftermarket for NA?

[Sarra]

Um, I don't think there are aftermarket valves for NA.

Since yall have better resources than I do could yall do some research and find out?

http://www.importperformanceparts.net/imports/ferreacompplus-subaru.htmlThanks. So which one should I get? How do you choose the right one?

[Sarra]

You need two intake and two exhaust per cylinder. Unless you do porting, don't get the +1 mm ones.

Might be of interest.Sarra had already pointed me towards that site. Thats where I am gonna get the valve springs and such. How much HP and/or TQ gain can I get from the Stage I cams? I doubt the Stage III cams will help me much but yall would know more than me so what do yall think I should get?

[Huffer]

To use more than Stage 1 cams you will need engine management. Are you prepared for that? You may also have to use premium fuel or at least 91-92 octane (R/M+2) to prevent knocking.

[J.McDonald Knives]

When I do the cams I had planned on engine management. Just need to find a good EM unit that I can have a couple of different settings saved. On for towing and the other for daily driving. Also have been trying to figure out how to make a pull out and swing out mount for a laptop so that I can tuck it behind the glove box lid so that you can't tell its there and I can lock the glove box door to help keep it safe.

[Huffer]

You'll need a pretty damn small laptop. The glovebox isn't exactly large.

You'll need a pretty damn small laptop. The glovebox isn't exactly large.Well I will be modding the glove box so that it can hold a bigger laptop. Basically its just gonna be a door and nothing else. Won't be able to hold anything in the pocket since I will be cutting that out.
