Unless you want to drift or something and actually want all the control a manual transmission provides AT will actually be faster around the track.

No one has REALLY tested it, or with upgraded valve bodies and with a tune to add pressure and with an oil cooler and such...
I wouldn't bet 500-500, but 450, maybe, but maybe with an upgraded flex plate and the other mods I mentioned, 500?

Now that you mentioned this so internally upgrading my AT tranny meaning a flex plate, VB, and posibbly a torque converter can help my car reach 500? *of course with tune and coolers added of course* I ask because I wanted to havethe parts ready by when my mhi kit gets shipped to install everything together?

Yeah, I'd for sure see the VB, MAYBE the flex plate and torque converter. I'd almost rather wait for those to fail.

You have a point but I've had my car for about 3 years and trust me I've had my fair share of spirited driving wouldn't ir be advisable to change those part when going FI in the near future? Well for safety precausions though?

Even with all of those parts replaced, the clutch packs in gears 5-7 are still too small to take a lot of power. Replacing those, adding a trans cooler and upping the line pressure would help, but torque will eventually kill it. The only solution so far is to call GTM and give them all of your money for one of their built autos.

It's still probably cheaper than swapping to a manual. The one guy that did it had to swap a lot of stuff out just to get it to run.

Wouldn't it just be cheaper to sell your car and buy a used 6MT Z? You might even be able to break even if you did it all private party. Much better then spending $1000s and the headaches involved in a swap.

Yeah, but how often are you going to be using all the power in 5th-7th? 5th takes you to 155 the limiter and I think 4th goes to 120~

But yeah, I agree, torque wil kill it. Better to SC the autos
