Luckily you have a BGB even though. There are large sections dedicated to diagnostics and troubleshooting. That may be in which I might start. It is going to guideline you better than just about any individual can. For your wealthy AFRs you will want to be looking throughout the circuits with the O2 sensor, MAP sensor and coolant temp sensors.
Are there any stores close to you which have a dyno and do tuning? Is there multiple store?? Take a couple of days and take a look at the store, ask to look at them even though they tune.
Though the Blacktop head contains a extra open combustion chamber (see “Head combustion- chambers”) it still has a higher static compression ratio (see “compression ratio”), this is solely due to the piston style and design. The Silvertop piston features a really smaller dome with two deeply angled exhaust flycuts, two moderate internal flycuts and a reasonable flat Center flycut for the center intake valve. The Blacktop piston is rather distinct, to support for your larger sized chamber the dome is significantly better with reduced flycuts. The exhaust flycuts are still current but additional shallow and only the center ingestion flycuts remains but even that is certainly merely a very small flat round dish machined out.
This engine was the initial inside the series to utilize Toyota's dual camshaft method called Higher-Mecha Twin Cam, exactly where the timing belt drives the exhaust camshaft along with the exhaust camshaft then drives the inlet camshaft by means of scissor gears.[eighteen][19][20] The inlet camshaft acts to be a slave camshaft on the exhaust camshaft (the latter performing like a master camshaft with the engine), which led to the process getting unofficially referred to as the "slave-cam process".
Need to i modify the mechanical linkage? ( they appear like function simultaneous ). I also discovered soon after i balanced the 4 cylinders to exact same air ingestion sum, one or two of these will raise or lessen the air intake amount by themselves, it would make me puzzled. Did you know wherever I am able to see the two procedures of balancing the ITB?
The Blacktop Alternatively attributes all however the smallest flat portion guiding the exhaust ports. This resulted in a sizable distinction between the combustion chamber volumes in which the Silvertop is 35cc (noted by Arias) as well as black at 37.8cc (measured by myself).
Will the ITB set up off of the 20v Focus on the 16v head? Or are classified as the heads a totaly distinctive design all by themselves?
jdm86gtz > I am possibly gonna give them a call and find out what can be carried out. I used to be seeking into acquiring one of their pnp units prior to, because a number of them do plug right in, Nonetheless they said that they wouldn't get the job done.
Also the Emanage blue appears to work quite perfectly With all the 20V, but that is a piggyback. Other piggybacks appears to be not to operate rather well with the 20v although the ECU is so sensible It will discovere the piggyback and adapt the placing.
At this time acquiring low-cost blacktops has gotten much easier. Getting nice blacktops seems to be more of a problem. Seems like more of these are all sludged up. Getting a pleasant silvertop is simpler.
We remained true to the first Toyota style and design, but utilized modern day Assessment and producing methods to handle troubles like uneven drinking water jacket cooling flows and port wall thicknesses.
its considerably from staying a 'pig' and you won't have to bodge anything besides wire while in the 20v TPS (reverse 4a-ge engine for sale of 16v TPS)
I cant see how on 16v electronics, I hooked everything up and at idle/minimal RPM there was fuck all vacuum.
This is some pics with the harnesses. the one Together with the blue tape is the 4age 20V Black prime harness. one other harness is a 7AFE manual harness. displaying many of the plug similarities.
