I don't know anything about 4 cylinders but I'm assuming you can port the head and possibly the intake/manifold as well. Pleas let me know if anyone has done this on a 4 cylinder and if you guys think it's worth doing.

Did it to my 97 DOHC neon and thought it was worth it, very time consuming but I'd probably do it to my SRT also but just the way its built it'll be very hard to go in and do it by hand. If i find a place that will like sand blast it then i might think about it.

I've done a couple 8s and a 6. All N/A. I'll tell you write now, get it paste exruded/hoaned and flowed. That is the best way, spare no expense on this. NO SHORT CUTS. Now, the IM is another thing. Wait a little bit and I'm sure someone will make a CNC one. Or you could take it off and deburr it with little to no difficulty. Don't worry about it being to smooth it's F/I and don't take it completely off the engine to work on it. It is not worth the chance destroying the oil rings and the turbo.

And as far as is it worth it......HELL YA!

I'm learning on making carbon fiber items and so if i get time i'll make different things. i'm wondering though can i use it to make the intake manifold. I thought the heat would be to much for it but i've seen pics with other cars that have the IM all carbon. I plan on doing a whole hood but thats a whole other topic :p

Carbon fiber has been used to make intakes. Many intakes today are plastic because of the lightweight and inherent smoothness.

Porting and polishing is great, but there are many things you should do to a turbo car way befor you ever need to worry about porting and polishing. Also porting is a science. just because you made things bigger you might have actually made flow worse.

I have plenty of experience porting 8 cylinder heads (Mustangs) and I know other mods normally come first, but like I said, I didn't know how a 4 cylinder head would respond. I totally agree, it's the quality of the porting not the quantity.

I had simple mods on my 4cyl chrystler conquest. I ported the head and the clutch started slipping afterwards. It makes a huge differenca on a turbo car.

I know the intake manifold on my Hemi and Dakota are not metal but some type of poly carbon material. Intesting materials since the heat that is generated by the truck is enormous.
