You can do this in Cali. There are rules that make it pricey, though. In particular, the engine and emmissions controls(all of them) must come from a road legal car the same year or newer than the chassis you're swapping in to. I.E. we need an ls3, Ls7, or Ls9 motor And full exhaust And obd2 setup. fun times.This is absolutely AMAZING!!! Too bad this is NOT street legal in the State of California...Cali sux again when it comes to motor swaps...especially motor swapping from different manufacturers. But this'd be awesome for whomever's got the dough for a sleeper at the track! ^_^
Wow, stumbled onto this thread today, after thinking of whether anyone has done an LS swap on a GC yet. I assume you guys are using a T56? I'm not familiar with the build that you pulled the LS1 from.
Did you try any off-the-shelf headers, or were you pretty much stuck with fabbing your own?
If this kit becomes viable, then I might just jump onto a current-gen GC. Otherwise, I think I'll see what next year's model has in store, transmission-wise.
Subbing for more updates. =D
