What is the best thing to Port under the hood of my car for the money???

[hawk362]

So I know for a fact I want to stay N/A dont ask me why I'm not sure yet, but anyways what would you guys reccommend to port polish under the hood of my car, would help the most hp wise, and be worth the cost??????? opcorn:

heads.. thats about it

What could i be looking at possible 5hp

[jason_bet]

I would think with that and mild cams you could see 25+.. but I dont no crap about NA.. so that is just a guess

That really depends on the port job. Porting and polishing isn't about removing material, it is about removing material from the right places. So, you might only get 5hp from a crap job. Find a good machinist that knows these heads and I'm sure you would see more. Pair that with a cam and a three angle valve job and you could see a good deal of power.

I would call someone at Dynamic Racing, see if they can help you or at least get you pointed in the right direction.

you'd be better off turbocharging..

yup..these guys are right.i have my NA heads port and polished, which by the way isnt a cheap thing to do..and depends on who does em to see what kinds of power..anywhere from 10-30 hp gains i would say..i also have my manifold and throttle body port and polished and my lower intake plenum..might as well do it all while its out..try a whole mess of bolt on hp adders first..cheaper..easier..

i have a couple of questions

is there a difference between the NA and TT heads? if so, would putting on the p&p TT heads be worth it on a base model related to cost?

also, how much of a difference is it to actually have those other things ported and polished??

is there any other throttle body that can be swapped that anyone knows of?

VR4 heads will flow a little better.

As for TB stick with stock. There are set ups making HUGE horsepower on stock TB. The TB is not a restriction.
