Question about BBTB.

Ok, first off I am wondering a set of Headers or a BBTB (65mm, Tigerlily form K Spec???), would put out the more noticable power increase. Right now I just have CAI, Catback and Iridium Plugs. If I go with the Throttle Body, will I have to Port/Polish or Match Port the Intake Manifold or what?

go for headers...yes you would have to port or you wont really notice anything from the bbtb

Porting & polishing is a good route to go if you're looking to stay NA. As Dawg said, without doing the upper & lower IM you won't see much of a gain. If you do go that route you should look into fuel tuning with a MAFterburner or SAFC2. Larger injectors might be needed as well.

Ok, any ideas on where to look for headers such as say, OBX.... Import Shark seems to consistantly and reliably be out stock of OBX headers up to 2001 models. I looked on the other few sights I know, such as KSpec, but the prices are gawdy compared to Imp Shark. :banghead:
