How do I run 13's?

[The Deuce]

If you do a 99+ head swap, and a blower, you'll need to do some serious work.

Step 1. Port the heads, to increase the size of the combustion chamber.
Step 2. Attach blower and blow up bottom end.
Step 3. Rebuild wiht Forged internals, at 8.5:1.
Step 4. Turn up the boost and hold on.

You're not going to see 13 without a power adder in that car. At least not if you plan on driving it daily. It's too darn heavy. Work on seeing 14's first.
