I can get a STR 70mm t/b for $290 and a skunk 2 intake mani for $200, I would port match the mani.

Do turbo cars see nice gains from this, head is completely worked, shooting for 300whp, how much of a whp gain would I be seeing?

Better to use somewhere else...?

 

my order of buying parts goes:

1. turbo kit
2. bottom end building
3. drivetrain
4. intake/ head mods

 

no

 

why not, like I said head is built to the ******* (A6) and block should be on its way shortly (Y7), turbo kit is slowly ocming together, money isnt tight so its cool

 

Since the head is "fully worked" you should see some gains by allowing more air to flow into it.

 

You will see some gains, but is your Turbo set-up and bottom end where you want it??

IMO your money would be better spent there first.

 

If money isnt a problem go for it, I can see your built head really liking it

p.s. If money isn't a problem, would you pick one up for me too, thanks

 

why would you port the mani? wouldnt you port the head to match the mani? arent the ports bigger on the manifold?

 

Getting a bigger TB is a waste of money. If your trying to boost say, 8psi, and you actually are, a 70mm TB is not going to make any more power then your stock one.
IM will make a difference, go for it.

 

howdo you figure that a bigger TB wont make a diff?
