Not at all! I was merely pointing out that in addition to the LS4's trans, the engine may not be able to last long with turbocharging. My statement wasn't aimed specifically at you, but at everyone who may have overlooked that fact. While I realize the L67 engines (3.8L supercharged) used in Pontiacs, Buicks and Chevys lasted (even when over-boosted with smaller aftermarket pulleys), they all used heavy-duty parts.

Anyways, the 4t65E-HD trans used in the L67/L32 cars was a good trans, but it did have its own problems after you dropped any lower then a 3.4 pulley and if you wanted to go cam, then you would have to beef up your trans of BOOM..!!!

Our engines are sleeved i don't think theres much chance of damaging the cylinder wall id be more worried about the piston rings. Even if someone does have a problem with the sleeves cracking i don't think they will notice it because there will still be the original bore there holding pressure. Not to mention there are some fiero people boring out the LS4 to 96mm the LS1 is 99 mm and not having any problems.

The problem with the Hemi kit is tuning, there's no problem with tuning for the LS4.
It's very similar to Diablo promising to have TCM capability......you just keep waiting and waiting and waiting and it never comes imagine relying on something like that for your turbo kit sales...brutal.
Kevin's PISSED since he's got kits ready to ship but no tuning.
With the LS4 kit, it's not like you're paying for a kit that is coming out at a later date, the kits are ready to go.

What you say is true. But why should Kevin withhold my refund because of it? I waited patiently for 1 1/2 years and have nothing to show for it. I don't want the kit even if Diablo finally comes through. I'll be selling the Charger soon and buying a G8 GXP.

2008 impala ss I've had my 08 impala ss for about two months now.. very happy w it.
Would like to start adding some performance upgrades. I was looking into a few things.. first was a cold air intake from this company called coldairinductions.com it looks pretty good. Next thing, since predator does not support the 08's yet does anyone know if the JET PCM will do what they claim it does for $227? And how about the JET mass air sensor? Will these products work? Last anyone know of any cheap exhaust tricks you can do to get car to perform a little better.. such as an exhaust by pass. Buddy of mine had this done to an 00 vette where they took a small pipe that ran from right before and right after mufflers. He said he can feel a difference and car sounds pretty good when at max rpm. Any advice would be greatly appreciated! Thanks John N
