I thought the Mach I's run on regular unless you had them tuned to run on 93.

Well aren't the 4vs running higher compression thus needing premium fuel? We need a Mach 1 owner to chime in on this thread and go check their fuel cover to see what it says.

if you can find one for that cheap...go original Mysitchrome Cobra. or you could always get yourself a V6 and stroke it 4.2. it is easily possible to make 300 whp with an NA V6. then you could have a sleeper to beat up on 2v GTs haha.

OR get an SVO with the turbo I4

Booyah I was right:

"Ratings for both are 305 hp at 5,800 and 320 lb-ft at 4,200 rpm. A 10.1:1 compression ratio requires premium fuel."
