Where to start??
 

Hey guys new to supras and was wondering where to start. I have an 89 Toyota supra non turbo I think it's in pretty good condition. Already replaced fan clutch distributor cap and rotor new shocks new spark plug and spark plug wires. Had it checked for misfires a while back got it fixed. But now I think I have a loss of power. Just wondering where to start on fixing or replacing parts to make my engine stronger please help me out 89 supra non turbo 7mge.

Spark plugs, belts, fuel filter... good way to start... Then go a lil more complex... Fuel filter

Brakes, always brakes first. Nothing more important for a moving object than the ability to stop (bullets and squirrels excepted).

I would actually suggest doing compression tests. Good way to see what condition the engine really is in. Can let you know where you actually need to start.

agree on the brakes as well...

thanks guys i had already changed the distributer cap and rotor, spark pulgs/wires, power steering belt, and fan clutch and was driving really strong for a while but now i feel a loss of power after 1st gear automatic tranny and doesnt shift into fourth the rpm just keeps rising never shifts and now i need new brakes and water pump it really sucks.please help my supra is old 89 and im trying to fix the wrongdoing of the last owner
