Ive been planing the 3.5 swap for about a month now, but am also going to turbo the beast. my question isnt about the swap itself, but the best rout to take for FI. Right now im going for the 3.5 heads but are not sure if i might be albe to make more power with the 3.o heads. I know this isnt the FI forum but i thought it might be better to ask here. Thanks

 

CR is your enemy with boost ... Stay w/ the 3.5 heads since 3.0 on 3.5 block raise it.

 

yup compression ration is very important in boosting 3.5's have 10.3:1 i believe

the ideal CR for a boosted VQ3X should be about 9.0:1

 

Not really, most people on here that boost stick w/ stock CR for 3.0L 10:1

 

Our motors seem to handle it quite well, too.

 

thanks for the advice now im going to start buying parts.
