I think this has been done before- just wondering if anyone out there had some better solutions...
I'm trying to use the Isuzu Impulse rear end for my V6 GT project. with that, I'll get
4" wider rear track
Limited slip dif
vented rear disks
and a rearend capable of handling a lot more power than I'm likely to get out of a naturally aspirated 3.4
the Isuzu rear seems like a logical choice since the track is nearly right, and you can just about bolt up the stock trailing arms to the GT pickup points. The panhard rod does go the oppisite way
Here's my issue:
Isuzu used a 4-link rear, and as we know, the Opel had a torque tube. I would like to break as few SCCA SM2 rules as possible, as this car might one day make it out to do some parking lot warfare. As such, I need to use the stock suspension pick-ups on the body. It would be pretty tricky getting the 4-link arms to attach to where the torque tube attaches to the body. The most logical approach at this point, so it seems to me, is to just cut the 4-link pickups off the isuzu rear and fab or cobble together a torque tube. I started taking apart the rear end from my parts car, looking for ideas or maybe something that I could used to adapt the Isuzu to a torque tube.
Just when I'm starting to feel real smart, I realize that the Isuzu rear end isn't really symetrical. DOH!!!! It's about 2 inches off center due to the way the housing's made (see pic)
Can I have a torque tube going off at some funny angle - which of course, it would seem I would pretty much have to fab it all myself. Which typically translates into it's going to be HEAVY.
Got any slicker solutions?
Sorry- pic is really dark, guess I sould've used the flash, huh?
