    7mgte no boost/oil in intercooler

    Oil in the ic and pipes is normal. Fix the accordion hose before going anywhere. 12 is the cps or wiring. The ne signal specifically which is used by the Ecu to determine engine rpm. Without that nothing runs. 25 is lean code 26 is rich code. Those could be o2 sensor. 51 is tps. Either...

    Starter Wiring Troubleshooting Adventure - Need Harness Pic

    To the ignition. Switch. You could eliminate it by putting a relay in. Or replace either the ignition switch or year the dash apart and replace that wire. Those are basically your only 2 options at this point. The relay is pretty common as it's the easiest and most common thing done to...

    spark blowout, plug gap Q's

    350 is about where you want to stop with the 440. Copper can last like 10-15k and at 1.60$ each doesn't really matter.

    spark blowout, plug gap Q's

    Iridiums are a pain to gap. And expensive. You can try gapping them farther to like 25 and see if that helps. But you shouldn't be seeing spark blow out at such low boost level esp with a stock turbo. Stock is platinum. Coppers also work very well but don't last as long. I run coppers and...

    New Turbo Install: Lags & Won't Boost (Part 2)

    The hose doesn't go to the throttle body for Eco. It's goes to the throttle so it can pull a vacuum on the engine. That is basic pcv functions. It was the even before the gas crisis on v8 with large displacement and big carbs. And since the pcv uses manifold vacuum and is after the throttle...

    New Turbo Install: Lags & Won't Boost (Part 2)

    Is the wastegate installed correctly? It's a knock off wastegate so it could be bad. Have you checked for codes? Have you performed a block test and compression test to rule out bhg? Have you checked the ignition timing? Have you checked the cam and crank timing? No really sure why you...

    Does coolant run through the IAC?

    If you adjust the idle screw you need to adjust the tps to match.

    Does coolant run through the IAC?

    Bypassing the coolant lines wont effect how it runs. Its more of preventive design and pretty much every engine manufactuer does it. Some people do drive there cars when its below freezing and thats when it will be useful as anti freeze doesnt freeze so it will help with your throttle not...

    IJZ MK3 Swap stumbles at 4000 rpm

    If you look at TOYOTA who made the car the pumps are different. sounds like a boost leak.

    Does coolant run through the IAC?

    Yes the 2 small ones are coolant. its so when in cols temps the engine will warm up and not freeze or stick. If your on stock ecu you need to run the big one to the intake before the turbo. when searching try searching with basic words and more than 3 letters. if 3 letters use * at the...

    IJZ MK3 Swap stumbles at 4000 rpm

    too good to be true?

    They prolly have kits for both motors. The turbo is junk. Most of the other stuff could be used but prolly wont fit right. Better off using a turbo kit from driftmotion.

    Headlights slightly off sync

    You may have gotten a bad integration relay. That's what I think it is being the only thing you changed. But I can say I have seen stranger things happen with electronics so you may have a weak motor. If double check all connections and fuses and alignment on the motors and all that first tho.
