Re: ITB Conversion on 16 valve 4AGE On my inventory bigport AW11 a leaking exhaust manifold gasket brought about the O2 sensor to go through lean and it pumped gas to the motor. Gas overall economy plummeted until I sorted it out.

iirc the throttle opener is utilised together with the ISCV as coldstart airsupply... which you still may possibly want With all the turbo setup pending of exactly what the vehicle is utilized for (i.e. useless on a racecar)

I didn't find the portion I had been looking for inside the BT handbook. Perhaps just because I failed to glance very long ample and it isn't searchable.

Although the automobile still run loaded Together with the new 1 on, then i simply just tested the MAP sensor by using a voltmeter, it shows in standard vary. To the coolant temperature sensor, i havent checked that right before since it is hidden deeply back again in the firewall, hard to reach. But my drinking water temperature gauge demonstrates ordinary readings, so ought to i suppose the Coolant Temp Sensor is okay?

For the primary gasoline feed line I filed 50 % the halt away so i could rotate the line a little bit more as the curvature it came down on fouled the manifold. Due to the fact my manfold no extended joins sound towards the engine I had to help make a ground extension wire to the manifold floor. I fastened them collectively and extended it to the head. I also produced a brace below it to guidance it, like the first manifold has

Just a little throttle to 50 % throttle is no dilemma and will not give vibrations btw. I'm accomplishing 28 mpg max now with straightforward driving and often reving to max 7k, but only at times!

past although not the very least There's the screw within the frontal experience with the ITB which is the adjuster to own air bypass the throttle plate even if shut (I've that completly shut)

iow, only starting to go down. Whenever you retard the timing, the spark plug will fireplace closer to TDC, along with the fuel/air blend will get to max stress in the event the piston is even further down the cylinder.

also the AFM isnt a restriction like people today Assume and I believe toyota thought another thing once they developed the ITB's in lieu of possessing kids operate open up ITB's.

Comes along with Blox vacuum box, OEM map sensor, Circuit hero TPS adpater, completely new TPS, mesh filter display screen, original velocity stack and also a extra matching velocity stack if you would like substitute/alter the modified one.
