I currently have MTI stage II heads, milled .030". I just ordered an ATI supercharger, and I want to lower my compression. Will changing the gaskets, pistons, rods, bearing, etc. be enough? Or, do I have to buy new heads?

You're at 10.4:1 - 10.5:1 now with the milling.

You can get by with that compression, but when you tune the car you might dialing back the timing a bit more than if you had stock 10.1:1 compression.

In an ideal world you would someday get some 70cc 6.0 heads and drop the compression down to 9.8:1 or less.

If I want run more boost, say 10psi, will new pistons and gaskets be enough, or do I need to buy 6.0 heads?

Thanks

The 6.0L heads, good tune, and YOU MUST HAVE AN INTERCOOLER....to try 10psi w/out an intercooler ur just a time bomb waiting to happen...bad batch of gas...ur buying a new shortblock. U could sell ur MTI heads for a set of ported 6.0L heads...just make sure they haven't been milled.

I thought the ATI chargers have an intercooler...?

I can move this thread into FI if you want, you would get a lot more replies.

I know buying them brand new from ATI u can get the 3core or the twin coolers...but he never mentioned who he was getting the blower from or if it was coming w/an intercooler....he just said ATI....in this game I don't take anything for granted anymore....I try and double check everything.
