I'm currently running on a D17stock internals and I have an interest in buying a new Port head system and get new Cams (Shafts and gears), along with piston heads and rods. Is itworth it?Also i know thatmost aftermarket Port n Polished heads are made for forced induction. If i dont use forced induction and get a new head is that alright as well? Thanks.

 

Its cam, not cams, as the d17 is sohc. The port head is just fine without forced induction, whoever told you that bit is wrong.

 

Sorry I know its just a SOHC just a typo. I also learned that the lower engine parts arent very supportive if you get your HP up pretty high which worries me because I am running a 50 shot of nitrous, are there any mods for the lower part of the engine to help out. Just dont want to blow anything because its also my dd.
