As I was CL shopping I found an 8.8 from a 98 for sale for 300, can I use it on my 06 v6 or no? Thanks for the help

 

No. Your car uses a 3 link system. Can't mount a 4 link unless you have a lot of fabrication skill. Plus I think that is narrower.

You have to use one from 2005+.

 

Gotcha, thank you very much for the help Jim, I also had a question about the x charger for you, I'm in the position now to actually buy one, but I'm a little worried about the internals, I need my car to be my DD for at least another 4 years, so should I get SSM heads and cams with the x charger xtreme?

 

I ran my car on the stock internals - everything top and bottom. It was my daily driver, on a 45 mile one way commute through sun, sleet, rain, hail, snow, and blizzards. The Xcharger went on at 90,000 miles (after 2 seasons on a 75 shot of nitrous). When I sold it in June after ordering the 2013 it had 203,000 miles on it, and was still running mid 12's. The new owner said compression checked out fine and he plans to race it this summer.

Gaylon (Nice Pony) put 150,000 miles on his Xcharger car as well. Only reason he had a blow up is because he does road courses - and on a long sweeping turn with less than a 1/4 tank of gas he went lean when the gas moved away from the pick up. Detonation resulted and chipped a piston; he was still able to drive it home though surprisingly.

So no need to worry about the 4.0. It is a very strong engine. You will be fine with the stock heads and cams. You might pick up some performance with the head change, but not any additional reliability.

 

Wow that's awesome, I've heard that the our pistons are the weak part though, is that true?

 

Detonation is the real killer. Make sure you have a good tune and run the proper octane. Gaylon went a long time and only chipped the piston (broke off at the top ring land as I recall) because of the sudden lean condition.

You will love the Xcharger. The scream in boost will make it tough not to kick it periodically! Don't go more than 3.55 on gears. Any more and the low end torque makes it tough to keep the rear tires planted

 

Good to know, thank you sir! I'm actually planning on getting gaylons kit for the tvs xcharger haha
