My supra has about 50 hp:( whats wrong?
 

Hi!

my supra turbo revs slow, sputters when i hit the gas. and is really powerless. its been sitting for 3 years so i?ve changed all vacuumlines and some hoses. The bov is halso replaced scince it was stuck in open.

The idle is close to perfect, and i get 0,45 bar (correct) boost from the turbo.

I am not getting any codes.

Anyone got an idea?

Check your timing.

ok, i will do that, but i cant find out how to do it, i?ve searched the forum without succes, and tsrm says i need a strobe light, cant it be done without a strobe light?

no you have to have a timing light to properly set the timing.

You should invest in one of these.

They are around 50$ at your local parts house.

Maybe you can rent one for a day. But you're going to need one full time at the drop of a dime.

what engine do you have? 7m? 1g? 1jz? check for loose connectors, vacuum hoses, and boost leaks. did you drain the old gas?

check fuel pressure. but first since its been sitting for 3 years i would go ahead and change the fluids the fuel filter. spark plugs, wires, stuff like that then try it. i have seen a cars fuel filter stop up when nothing is going through it for a while kinda like gum up. but never stopped working. if your not getting enoguh fuel your not gonna get power. same with air check intake clean filter. or replace depending on what your doing. but i would recommend check fuel pressure on a 1989 toyota supra turbo 7mgte it should be around 35-45 psi running. when you turn the key it should go up to somewhere around there if it doesnt i would first change fuel filter then check agian.

parts you need:

fuel pressure kit
line dissconnect tool
metric set of wrenches
sockets and rachets

its very simple the fuel filter is located right next to the lsd ( limited slip differential) i dont remeber exactly where but close really close. then check it out agian with the fuel pressure guage.. also since its been sitting for 3 years the gasoline might have lost its volatility so you might wanna get some 93 octane and throw in there and see if that helps. or octane booster thats prolly a better price then 4 something damn dollars for a gallon. if that doesnt work post that it didnt work and i will try to come up with something else.

Great advice!!!

well i try my best let me know if anything works. that i gave you advice on
