Re: Looking for new upgrades!?

I wouldn't mill the heads just for the sake of gaining a hair more compression. Because if something happens and you have to mill them to correct warpage you may not be able too.

Yeah true. I'm thinking of maybe doing a cam upgrade while the motor is apart

Re: Looking for new upgrades!?

I see you have done the exhaust but is there any gain doing the headers too?

Re: Looking for new upgrades!?

Just outta interest, why did you remove the SC tune?

I've done; SC '91 octane toon, K&N FIPK 77, F&B 72mm TB, 3" sports cat + free flow exhaust.

As soon as I added the F&B TB it lost all top end grunt, infact, doesn't even rev past 4>4.5k anymore. Need a toon bad, thankfully I don't need to drive the Jeep daily since it may do more harm than good. Although, I feel the SC one is better than stock!

Anyhow, check out Air-Ram's site! Loads of goodies to drool over there; CNC ported heads, '08 intake +TB adapter, TBs, SCT tuning, HO cams (I believe he knows a machine shop to re-grind them too), ATI damper + U/D pullies, and all the internal stuff too (pistons, H-Beams, bolts etc.). Even upgraded trannies.

I'm getting exited now so will leave it there - go to airram.com
