NA and Turbo Heads

[mk3supreme]

Are the NA and turbo heads the same? I believe someone told they are the same but I'm not sure, I was thinking of buying one for my 87 turbo and putting on.

There the same..

heads are the same but isnt the exhaust cam different?

 

[PorterzSupra]

Yes just the cams are a little more aggressive on the exhaust side so you get more power

So i'd be better off using N/A cams on a GTE? How much more power we lookin at? I might do this when I rebuild a GTE.

 

[NDBoost]

you only need to do exhaust side cam, not sure about the actual increase in power. you might get better throttle response or something like that..

 

[DEFIANT 7M]

To be honest the debate on the cam increase of power, will have you reading for hours. For all praticle purpose the heads are the same.

I think the part numbers are the same on the exhaust. Maybe not. But the intake cam had a bit more lift. Barely.

Yah, to my understanding, the exh cams are the same. The intake only moves the power band up on the scale but does not increase horsepower. This is all from what I have been reading from all the other post on the subject. I don't know how true it is though as I haven't changed out the cam to find out.

I bought a rebuilt head from clear water cylinder-head. When I asked they said that there is no difference between the two heads. They had measured the cams, valves, clearences and all that. They told me they found no differnece at all whatsoever. So hope that will help.

we've been through the cam discussion MANY times... it's just not worth it. all it's going to do is change the powerband a bit... you'll end up choking your motor if you ever go for big power...
