OK, we have all seen the ridiculous power numbers that this midget motor can make with a simple turbo. Has me thinking fast thoughts. BUT, what transmission can handle 700hp and 600ft pounds? Will I have to go to a drag built Powerglide, or can a 4L60E handle this? Can a regular T-5 deal with it? Not that I'm going to do this next week, but there are some derelict RX7s around here for cheap. I think I can do this for challenge money. Maybe.

T5? No. 4L60E? No. 4L80E? With proper build up, yes. Much cheaper route would be a well built TH350 or TH400. Muncie 4-speed (M-21, M-22) could do it too. A properly prepped T56 could do it as well. You'll have more money in a trans than the motor most likely. Then you need to make a rear end to handle it and a suspension that will hook up, and then.....

If you do ALL the available upgrades to the 60, you may as well get an 80 halfass built for less money and will handle more power. The weak links in the 60 is the powerflow plus gearing. No way do you need a 3.06 first gear in ANYTHING with an automatic.

There are gearsets out there that can handle that. Of course, the turbocharger works well with the torque converter; a manual valvebodied 4l80e would be the bees-knees (or, a 6L80E!111!!)

Challenge money makes me think built TH350.

OK, looking over e-bay, I see racing TH350s for 800.00 to 1200.00. Full B&M race rebuild kit for 155.00. Is rebuilding a TH350 something I could consider? No transmission experience.

Buy a 4l80e for ~$300 used and run it until you blow it up. Then buy another used one.

I'm concerned about the LOW first gear. Light car, 5-600ft#, low gear equals large smoke cloud and not much forward motion.

Isn't the 60e 3.xx first while the 80e is 2.xx?

Don't know, but that would be a lot better.

Opposite. Low gear equals better launch. High gear equals smoke show.

No, Zw. Lower gears, numerically higher, make for a greater chance of going up in smoke because you can overpower the mechanical limits of the tire against the ground. This is even greater when you lower the overall weight.

Mike has always had this idea that limiting the rotational speed of said tire on launch vs rpm somehow prevents wheelspin. I have no idea where he came up with this idea, but I've heard him preach it for 6 years

Oh boy.....
EDIT: IF that was the case, Powerglides would never work.
