Re: ITB Conversion on sixteen valve 4AGE On my inventory bigport AW11 a leaking exhaust manifold gasket brought on the O2 sensor to go through lean and it pumped gasoline into your motor. Gas financial state plummeted until I sorted it out.
It can be almost nothing much more than a historic quirk that puts Europe at the best on the map. The truth is (plus your government does not want you to grasp this) that NZ is UP and also you all are DOWN
we is going to be to start with unbinding finish the 4AGE harness together with the 7AFE harness, individual the body wiring from your engine wiring of each, and Mix the 4AGE engine wiring Using the 7AFE overall body wiring.
While both equally engines aspect a thick gasket/heat insulator between The top along with the inlet manifold the Blacktop and apparently the afterwards Silvertop models feature a trapezoid Slash-out in lieu of a square Slice-out in provision for that fuel path out of the injector.
"also (the AFM isnt a restriction like folks Believe and I think toyota considered something else) every time they created the ITB's as opposed to owning Little ones run open up ITB's."
– The easiest way to discover if there is a problem is to simply drive with and with no it staying disabled. Simply just unclip the plug in the VVT solenoid and execute a examination push.
I drove the vehicle as my day-to-day for each week or two following i acquired it. The engine ran good. Pulled really click here difficult. Tranny shifts silky sleek.
I created myself a dodgy exam item outside of PVC and sikaflex while I create a new one, But The end result was excellent, the car drives and idles much better than it did over the stock manifold. Has complete chilly start off idle and sits at about 1000rpm for regular warm idle.
Also the Emanage blue seems to do the job very effectively Along with the 20V, but this can be a piggyback. Other piggybacks looks not to operate rather well While using the 20v while the ECU is so sensible it'll discovere the piggyback and adapt the location.
Im guessing that just the Large Open Throttle(WOT) ignition timing curves have been altered on these automobiles for our fuel, due to the fact thats is where by detonation/knocking would occur, but I can be Erroneous.
To generally be trustworthy for any boosted application I would personally would toss all of it out and in good shape a plenum with one throttle - lighter, significantly less to go Mistaken, neat but that is just me.
Re: ITB Conversion on 16 valve 4AGE the blacktops ran MAP sensors so there have to be a technique for getting a fantastic MAP signal.
The Silvertop in its inlet ports has no set dividers as such and encompasses a substantial inner quantity. The Blacktop engine on the other hand has something extra resembling 3 tubes with two dividers.
Fortunately you've got a BGB nevertheless. You can find huge sections dedicated to diagnostics and troubleshooting. That is the place I'd personally begin. It will tutorial you better than pretty much anybody can. To the loaded AFRs you will want to be looking around the circuits in the O2 sensor, MAP sensor and coolant temp sensors.
