Larger heads?
 
I was discussing with someone my pans for getting a turbo among other things to increase the hp of my 95 pro and he suggested getting larger heads for the engine. does anyone know if we can do this? and has any one done it already?

you can get the existing heads machined

Will that give any kind of increased horsepower?

Pigeon Jun 26, 2002 04:50 PM

I havent done it, nor do I know anybody that has, but it will increase horsepower, and u will notice a difference
i could probably expect around a 15hp increase

that would be if u ported and polished the head and got a 3 angle valve job

the things is that it is an expensive procedure because taking off and on the heads alone is going to cost u over 500 in labour anyways

none the less, it would be a very cool mod

also, if u have the 1.8L engine, you could just buy a performance head already ported and polished and everything
it is sold by GUDE PERFORMANCE

ive read about people that has done that, and there has been positive feed back

I don't have a 1.8L but the way it sounds more an dmore i'm thinking of just getting one cause it will cost the same price to get mine up to where a 1.8 is so why not just get a 1.8 and then make that one better. thanks for the info man.

no problem

honestly, ur right
thats the best way to go

i have the 1.5L too, but all i did was a cold air intake, exhaust, and some plug wires

now im just waiting till i swap in the 1.8
