Buy the Toyota head gasket kit and everything else aftermarket. eBay has some good stuff but they have some bad stuff too. I bought the head gasket kit from eBay and used almost everything except the head gasket because I didn't need it at that time. It also doesn't come with all the intake gaskets, it's missing the upper Y gasket.

 

I'd personally pick up new head bolts as well. I believe the current ones are probably shot after all them miles and the overheats. More money..but a good precaution.

 

I forgot that one, I would change them even if they had a 100 miles on them, because they are torque to yield Bolts.

 

I would buy the coolant, sealant, water pump, head gasket and frontseals from Toyota. Supra non-turbo parts are the same. I would get everything else aftermarket. I would change the plugs, plug wires and valve cover gasket while you are there.

 

thanks 2gsc300 i almost forgot about the wires n spark plugs,i did some research on the water pump for toyota n aftermarket n i found one aftermarket that is o.e not o.e.m but is to act like oem i know lots of people agree to get oem but i havelots of people telling me other wise like the headgasket even thou the oem is suppose to be better but its a metal headgasket just like the aftermarket n works the same unless u get a 2ply head gasket or copper one .i kno oem timing belt forsure i got to get n i decided to get the fluids n filter for the trans from toyota
