I need some help finding info about the f20 2000model s2k how much can everything hold like the stock bottom end tranny and rear lsd?? IM looking at buying a friends it has a T28 duel ball bearing, 750-780?? cc injectors and 255 fuel pump, AEM ems, the problem is we think the piston rings have had it so IM thinking of the best possible ways to get things going and maybe purchase the car. the car made 360 whp at 14 psi he then ran 20 and the rings went so...

 

Do compression and leakdown tests to verify bad cylinder sealing. If it fails, be prepared to spend some money getting it back in shape. Rings could be bad, cylinder bores scuffed, or valves bent. Unless you're an experienced wrench, this could be a lot of trouble and expense.
