said it was a horrible idea as I would loose a ton of torque putting a 4 cyl in a Z. But a slicktop ways 3,1xx lbs with a cast iron v6. Having an aluminum 4 cyl engine, and 405 at the wheels and an even lighter car weight would certainly haul ass. But the electronics and engine mounts would have been a bitch. I wish I coulda hung on to the slicktop Z as a spare car for when i graduate from college and am going to have money to toy around. Either a vg30dett or sr20det swap on that car would have been a lot of fun.
