I have a 87 TII and I have stock ports and I looking for a good turbo with minimum lag time. I will upgrade my computer ,exhaust , computer and fuel system. I looking at 450 to 500 hp. Also any suggestions on what I must do to achieve this hp. Thanks guys

 

I'am by far no expert but on stock ports your hoping for alot. There is a time where you have to ask yourself...."Do I want Power or response?"

Goodluck with your choice and check the FAQ's often, you'll find that your experts have already discussed it many of times

Goodluck!

 

no such thing

 

what about with a mild port?

 

Actually ther is a such thing.

I recently build and tuned an FB rx7 for a customer.

Engine was dowelled, but ports were COMPLETELY STOCK.

I used a GT35/40 with a 1.06 Rear.
Short runner manifold with 1 1/2 ID pipe.
60mm wastegate

Car made 385rwhp on 15psi and 432rwhp on 20psi on pump fuel. So that is pretty much 500bhp.

Its actually a very good combo, a heap of torque and power to 8000rpm.
Just incase anyone doubts the HP.

On 15psi it ran 127mph, on 20psi it ran 134mph.

 

I don't doubt the ability to make the hp, I doubt the abality to make it with minium lag.

 

Why not give it a healthy port? You need to move out of cali
