Not to play who has the bigger dick but I ran 2 MS3's this year and won both from a Dig...
I can launch, they really cant. The 07/08 stock Z's run about a low to mid 13 stock. Its not just the dual throttle setup, its also because the engine pulls about 30 more HP than last DE model engine and has an increased redline of 500rpm with 80% new internals.
As for my SRT-4...thats a wholeee nother story. I had a stage 2 setup with a 100 shot of nitrous and many other goodies and boost turned way up, TBE, return line, etc.
But yea anyway...I love these MS3's and recomended them to Monkey, cuz the SRT-4 caliber is COMPLETE and utter JUNK.
Other than that the WRX is way overpriced and the GTI is way too slow.
I think that only leaves us with the new Cobalt Turbo which still looks like a cobalt so BLEH.
