Have a reliable DD 314 HP Supra, with parts I can buy from Toyota, until they run out of stock. Brought the Supra up to Toyota's usual reliability standard, after replacing their stock head gasket with an HKS stopper gasket and ARP head bolts, so now it's all about maintainance. In that vien, I had the radiator rodded out and also replaced the fan shroud, thermostat and rad cap, and fill with 50/50 PEG and water. Now the engine will stay reliably within design specs even on 100 degree days. Van
