For intake you mean the plastic manifold under the plenum right, i was going to get the typhoon intake manifold, what is wrong with the heads that come one the 98's that they need to be changed.

the heads are extremly restrective. even with bolton's on, on a non pi u won't see much gain the holes are just too small. as for the intake yes. but i wouldn't waste my money on the typhoon. just get the stock pi one. it is a great deal cheaper and only like 2 hp less. but if u really don't want a plastic one wait for trick flows intake manifold to come out. it comes out it the spring, a little pricy but much better than the pi one and stonger too. (won't have to worry about the water passage cracking anymore)

I do not think an aluminum driveshaft did that much for me. I do think however it is cool to add that in a when you talk to people who do not know much about cars. LOL I get the same response when I say i have cams as I do when I say have an aluminum driveshaft. There like wow it must be fast. HAHAHA

PI Swap, Phssss Look at VT for stage II heads and cams. I think it might be just a little more than the alum drive shaft though.

You have to watch with stage two heads and cams on a PI swapped car. The PTV clearance is smaller because of the flat top pistons. A stage two head might work but probably not a stage two cam. It depends on the duration and lift.

Twas an example, not some thing u should go out and buy without talkin to experts.
