Not a lot of engine mods are allowed in ITR. All that is allowed is .5 bump in compression, good valve job, 1" port match, .040" over bore, which I can't do since you can't bore the cylinders and I can't use Nickes. I can use any header/exhaust system and any air intake. Any programmable ecu is allowed. Right now I have a stock 41k mile engine in it now.
