I was wondering when the stock head gaskets start to fail on first gen 1u's? Can they withstand the cylinder pressures of 400-500 whp? Just wondering if it was possible like it is on a 2j. Unlike my7m which needs hg and studs at anything above vacume.
guess i got some miss-information. someone told me if you had a 89+ supra that the sc400 motor would bolt in. i thought it was feesable since they are both rear sump and the 89+ have the new style mounts. if i have to make mounts i'm gonna keep the early style subframe
