Need some info from the club.
Any of you folks out there using an H190 diff in your car and if so, what motor and HP are you running? CA18DET or SR20DET?

I am putting a supercharged Z24 motor in mine with a 50hp shot of Nitrous. I had the same setup in my car but with a built A15 motor. I was using an H165 rearend that had the spider gears welded. I broke the axle after one season of drag racing. I purchased an H190 rearend which I will be welding up as well.
I finally got around to removing the H165 from the car and paired both axles up. By eyeballing it, the H190 appears to be only 2 milimeters in diameter bigger.
The H190 diff came out of a 1970 Roadster.

Will that be good enough for my new setup or will I break that one to?

Thanks for any help.
