What are you looking to make on this new motor, or is the transaxle the hold back?

The transaxle is pretty robust. But parts aren't easy to come by at times. If you really destroy one that requires just replacing it, a used one is like $20k. And they almost never come up for sale. So I would like to stay away from hard lauches and power shifting it. haha

I am using the same turbos that it already has. So no more power to really be had. Especially with the turbine side being so small.

Once you go over 800 crank hp, the mods needed to make more power pile on quickly. Aftermarket turbo kit, triple-disc clutch, complete fuel system, billit intake manifold, axle shafts, and so on. So once you jump over that 800 hp mark, you are talking BIG money to go full boogie. And in a short-wheelbase, AWD car, it's more than a handful. lol

Yep, so 620whp it is lol. , 20k for a trans is retarded GTR type stuff, i love cars, but no way could i stomach that kind of cash for a trans, only to have it break again too.

Now you can see why I am reluctant to drag race the car. lol

Heck, I had a hard time accepting spending that kind of money on a motor rebuild. haha Next time it's getting a junkyard LS. :rofl:

The chances are I would never have an issue outside of the normal wear items like synchros. I would probably break axles first. But I'm not willing to take the risk. I knew it when I bought the car. I have no real desire to drag race it. Especially as hard as it is to launch well. It's either bog or wheel hop. haha The wheel hop might be gone since I did the bushings, toe arms, springs, etc. But I enjoy the car on the road course way more than the drag strip. So I keep focusing on that.

If I wanted a drag 911, I would have not made the manual trans a necessity. Then went with the newer 991.1 Turbo with the PDK. With the mods I have on this one, it would go into the 9's.

I enjoy driving the car with the manual trans. No regrets at all.
