N/a Power ?

[murdered96]

Well higher compressin means power right?
For my to go from 9.4 to 10.5 compression you have to mill the head .035" .... Can i use the same regular fuel though?

I want to keep this one n/a w/ welded rear instead of the turbo and 8.8.

FOR POWER...
Its a 1996 2.3 5sp and is a daily driver and a budget build except the head because thats something i cannot do myself. I drive mostly around 3k rpm but never over 4k but it feels like it still wants to pull.

Should i keep the stock head and port and polish that with what cam?
Maybe a cam that takes the rpm to 7k....does the cam do that?

(free)Gutted tc upper intake kniffed lowers and a custom cold air intake is the plan for the intake..

(free)Is dual 2" exhaust too much? what about after the head work?

1 If its a daily driver don't weld it!

2 The only way you'll make more power without forced induction is to increase displacement or spin it faster. Ported head, camshaft, free flowing intake and exhaust will allow more air through the motor at high rpm. If this is a daily driver again you DON'T want this. For the small gain in power on the right side of the tach, you're going to regret the shift in the torque curve (expect to drive at 3-4K when cruising).

All the money you'll have in custom camshaft, high compression pistons, head work, ect... you could easily locate a turbocoupe donor 2.3L and make a lot more "usable" power than you will ever see N/A.

Tc intakes won't bolt onto your head, not same bolt pattern... You need to keep the stock ones..

You could have a performance cam that would make more power in beetween 4500-7000 rpm, but I don't see the point of having this if you never go over 4k? And like he said you are going to lose low end power. You would also need stiffer springs to get high rpms, and stock 96 rods also don't like high revving..

Building a 200 whp N/A is possible, but you will end up putting more money into it than if you do a TC swap or build this engine for turbo.

Back to your first ? about compression and fuel. If you put a mild cam in it you will not need to run higher octane fuel with a mildly milled head. A performance camshaft holds the valves open longer thus reducing your dynamic compression ratio.

From my experience just dropping in a .420 lift cam only hurts power under 2000 rev. By about 2300-2500 you can tell an increase in power. This was on a stock motor with stock manifold. Bigger exhaust and ported head will deffinately raise the torque curve though. If you have low enough gears a mild cam is fine on a dd.
