Specifically, the LS6. The LS7 dry sump system is not great, it is more of a hybrid dry/wet sump system. If you're dead set on a dry sumped motor look into the LS3 in the new Grand Sport, it supposedly was much improved as the intent was that the GS was going to be the track package. It's so easy to get power from an LSx motor that you can get the LS3 to make Z06 power for less than $1000. I also struggle with your need to keep ASR. ABS, absolutely, but ASR? Piggybacking a mechanical traction system over a fully electronically controlled throttle seems risky. Not to mention the herculean effort. I'll suggest the same thing you you always suggest  List your goals for the project. If you are dead set on the LS7 because it would be "super cool" then ok, but if you're just looking for a cool project that massively improves your C4 then I'd choose a different path. I did a LOT of research on 93 to 94+ harness conversions and it's not so bad. You don't need to rewire the entire car, the painless harnesses have few connections that penetrate the firewall. I have one. I'd also consider using alternate sources for your signals. Why not use GPS for VSS? If you do tackle a project of this magnitude then let's get really creative and make a one of a kind. I can show you how to retrofit an ABS module from another vehicle (read: more modern) and perform ABS and TCS the right way, electronically. But we're talking a few thousand for the system... All that said, however, my suggestion: Gut the car and race it |
