Hey guys, I have some questions for the FI crowd. I'm building a 1988 bmw 325is. I have a 2002 lm7 with 50k miles and a truck 4l60e. Planned upgrades for the tranny include:

transgo hd2 shift kit
corvette servo
Sonnax 2-3 shift valve
Large trans cooler
2200-2800 stall (undecided yet)

The motor is getting a hybrid Denmah turbo setup. gt45 turbo, blah blah blah.

Questions for the you guys, this is full race car if you will, stripped to nothing (literally all the undercoat is gone), stitch welded, getting a cage in the next week or two. it's very light and targeted finish weight is 2500# with driver.

Will the 4l60e handle the setup, this IS NOT A DRAG CAR. So no hard launches, suspension isn't setup for that. I'm aiming for a 500-550whp range.

Your thoughts?

If you build it right yes no problem. I have 900whp and 3800lbs with a tbrake and my 4l60 holds up. I have a level 7 flt. Keep it cool.

Yeah I forgot to put the LARGE trans cooler in my list.

With a good trans cooler, the 60e will do well in a light car

Thats good to hear. I wasn't overly concerned but figured I would ask the question.

My 4000lb GTO just went 144mph with my built 4L65e.
Seems to handle 800whp just fine.

what makes a it a 4l6(5)e? Internally what is the difference. My buddy had one in his T/A and he could never give me a straight answer.
