anyone care to show wirings technique? please...

YEs!! running the motor would be my idea. But how to test the motor since there is only motor with harness and ECU. WHat should I do to get it running? Thank you.

guys, i came across this question I cant figure out... how??? ANyway, I was shopping for 1JZ motor. how to test a motor when it is already pulled out of car(no longer a halfcut), however, wirings all there. As far as I know, I need a gas pump to supply gas to motor, a 12v battery, ecu...

Got such thing cast iron manifold for 1JZ-GTE? If yes, where to get it?

hi, which type of oil pan location is good? front, mid, or rear?

AF1JZ, I had exactly same problem as you described. I did all possible things like checking leaks, bov, wiring, map sensor... finally, I pulled out the twins, the turbo looks fine to me. I guess, I spent too much time diagnostic problems. Finally, I just throw in single turbo from skyline R33...

can anyone show me where is the sensor? I have gone to single turbo and did a little piping on the intake and intercooler piping. My gas mileage quite bad.

thank you for your help. really appreciate that. I was told the sensor I bought is OEM o2 sensor from 7MGTE. Lets summarized the problem. Since white is o2 meaning the wiring will be like this: WHITE->BLUE, THEN 2 BLACKS-> BLK/RED & RED/GREEN? pLEASE CORRECT IF i AM WRONG. THANK YOU.

I need help. I am replacing a used o2 sensor, wirings on my 1jz is different from the sensor. I was told the sensor is from 7Mgte. So, the o2 sensor has 1 blue and 2 blacks, while my 1jz has 1 white, 1 red/green and 1 black/red. How should I wire them?

sorry for confusion, bubbles = soap(foam created from soap). anyway, thanks for explaination. I hope I can get back my "1JZ power" asap... :naughty:

OK, here is my plan. As annoyingrb suggest sealing air filter and put some pressure into the intake manifold to check air leak. However, question is, will the air pressure leak through turbo gasket or turbo exhaust when i apply air pressure?? 2nd, I need to seal the air intake manifold to...

How do I check boost leak? I know I read it about taking off turbo, I was told the job is tough to remove turbo. So, I would check boost leak 1st. anyway, thank you all very much..

could it be A/C?

yes, i have boost gauge. When idling, the gauge shows about <500mmHg, when boosting at about 4500rpm, the gauge shows about 6psi. I will check fuel filter this weekend. By the way, how posibility it could be my fuel pump not strong enough and fuel pump filter clog??

hi guys, i need a little help here. I was told I have a bad turbo. Anyway, here is my case. from 0 mph... with WOT from 1st gear, 2nd gear 3rd gear.. the car moving pretty fast, as soon as the car goes smoothly at 5th gear, I wanted more power and thus step the gas pedal all the away, I felt no...

check your ECU. open up the cover and you can find any burned or black mark.

you have bad ECU... probably the resistors for injectors burned out. it happened to me... send to shop to replace the resistor, works great!!

ok... i found some vacuum is not connected but i dont know what it is and have no idea where they go. I will take pic, pls show me... BTW, 1JZ MAP sensor=turbo pressure sensor?

yes, the car idle fine, if i press gas pedal, the motor will rev smoothly.

hi guys, i need help here. My 1JZ seems lack of power, when i put more pressure on gas pedal, the engine doesnt response at all, when I continue pressing gas pedal, the engine started choking ..... sounds like misfiring. what could be my problems? I was told the it could be TPS or low on fuel...
