    Need help with my rebuild

    It could. The engine doesnt know air is coming in. You cant fix a broken afm.

    Need help with my rebuild

    Ya if you broke the part that goes in the housing its prolly bad. I'd look for a new one.

    1JZ swap won't start

    The other side gets grounded when it needs to fire. Do you have spark? Jump fp and b+ and see if the fuel pump comes on. If it does try to start.

    Ma70 instrument cluster woes

    Ya that's the same as any engine swap. Without the ground on the m1 plug the gauges do funny things.

    ffim on 87 7mgte

    Moved. The build up gallery is not for questions of the type you asked. When you have no afm it's because there is a map sensor I place of the afm. Either from maft pro or a standalone. A ffim is a front facing Intake manifold.

    Wastegates for 500hp

    The wastegate will vent the same amount as soon as the target boost level is reached. Its either open or closed. The less amount of time for high boost is not much at all. maybe a couple seconds tops.

    1JZ swap won't start

    Ya you need fresh gas. Old gas never works well. Could also use a charger to start it.

    Rough idle & acceleration. Codes 24, 34, 42 & 52...

    Boost leak is after the turbo. So when your leaking air the turbo is spooling up more because the wastegate is not opening and sucking more air past the afm.

    Wastegates for 500hp

    So your saying i can reliably control boost on a 1k hp 2j with a 38mm gate? The wastegate is what controls boost and boost is a major factor of hp on a turbo engine. But there is not set gate size for a certian hp.

    Getting those are not going to raise fuel cut. When you outflow the stock afm you hit fuel cut. Either get at a lexus afm or go standalone.

    Wastegates for 500hp

    Tial is 44 and pte is 46. Iirc they use the same flange tho. Depending on boost levels and talking about crank or wheel hp. A single 44 would prolly be plenty.

    7m is non interferrance meaning valve could be all the way open at tdc and nothing will hit. No1 will be at tdc compression while no 6 will be at end of exhaust stroke and Begining of intake stroke so both intake and exhaust valves could be slightly open. 24 is afm and 34 is boost leak. I'd...

    It would be better to keep the splash shield for cooling and aero. Race cars all use flat bottoms.
