It's not a bad idea, but it's going to add significantly to your labor costs.

Yea that's what i figured and the flex plate itself is pretty expensive.

Any thoughts on Exedy Technics Automatic Transmission Sports Clutch Set - for 7AT.

Trying to beef up my transmission.

If you want to beef up the 7AT, talk to Fast Intentions or Level 10. Although, it's probably not as necessary with a supercharger as it would be with a turbo. If I had an auto and was doing your build, I'd set aside the cash for a built transmission and wait until the stock one pops.

Honestly, since you're starting with a base Z, I'd consider brakes and LSD to be more pressing needs than the tranny.

The key to AT life is mostly in the tune. I know people that have had their AT's blow on them on the dyno because the tuner has no idea what he is doing with line pressure and such. The guy local to me lost his tranny at 320wtq because the tuner was ignorant.

Sebs (sebastian from Specialty Z) says he can reliably tune way past 450wtq. and he does all day long. The tune will make or break your system.

GET A GOOD TUNER!.....Just use sebs.

This is exactly what I am doing. I didn't see anything about transmission stuff on the FI website other than the flexplate. I know that Level Ten advertises a tranny built to 700+ hp for close to 5k. Hopefully mine doesn't give too soon...

What is the purpose of the TBatt idler pulley? Someone was recommending it too.

To reduce or eliminate serp belt slip. I have one and it's done the trick.

I think i remember reading that the slippage occurs when you upgrade to a 9lb pulley, right? The stock one is 8lb.

Slippage will still occur with the stock 8lb pulley. "Coincidentally" it seems to happen around the time the SC peaks out at 8psi. With the TBatt extra idler that eliminates the slip, I believe folks are seeing near, if not above, 9lbs on the stock pulley. Once I've resolved my injector issue, I'll let you know.

Has anybody here built their own kit? I was in the process of rebuilding a V3, going to get the air-air, called stillen but they won't let me order the SC mounting bracket or manifold. Seeing if there are any recommendations locally for someone to make a mounting bracket, but what about the manifold as well?

I tried to install the extra pulley with the 8lb pulley and the green belt was too short wouldn't fit. Any one else have this issue?

Make sure that you are not over the side on any of the pulleys and that you have it routed the correct way. I have the same pulley setup and the green belt that TBatt sent with it fit like a glove. What is the belt #?
