oops .. lol .. clicked enter ..

but neways .. i bought a 89 mr2 sc.. and i recieved 2 motors with the car .. one newly build ..

and then other the stock block and internals ..

the newly built one was a n/a .. didnt know untill driving the car

i assembled the car (bought in pieces) and as soon as i started the car the head gasket gave out partially .. and fully blown after 14 miles (smoke pouring out the back and oil and coolant pissing out of the exhuast

so .. if you do want to put a supercharger on a n/a .. you have to build everything perfect ... metal headgasket .. arp head bolts ..

and when you initially start the car you must unplug the supercharger and break in the motor .. then after break in .. somehow apply 1 pound of boost per week untill you get up to 8 ..

these are the instructions i got from the guy who built the motor .. after i blow it .. lol ..

so now i rebuilt the stock 4agze and its purring like a kitten .. but has nowhere near the amount of torque and hp from the high comp pistons ..

also .. you may have to use high octane fuel (premium) and octane booster .. to avoid detonation ..

long story short .. if you can keep the head gasket from saying goodbye .. then go for it .. definitly worth it unless you plan to do a v6 or 3sgte swap .. then i would just start saving money ..
