Re: ITB Conversion on sixteen valve 4AGE On my stock bigport AW11 a leaking exhaust manifold gasket triggered the O2 sensor to go through lean and it pumped fuel into your motor. Fuel economic climate plummeted until I sorted it out.
4AGE 20v ITB vacuum Directions on Intecracing.com can't help with all the rest of the pipeing as it's a bit bewildering but I am able to tell you precisely what the ports on the ITBs are...
Using readings with the O2 with no diagnostic port jumped will let you know what it is looking through. This is a superb diagnostic action.

16V and Silvertop engines all utilize a rubber dampener amongst the middle Element of the most crucial crank pulley and each of two outer pulley rows. The Blacktop Conversely only has dampening on the pulley row which is around the facet closer for the engine, as such the outwards struggling with row to the pulley which happens to be the one which probably drives the ability steering pump along with a/C compressor is just not dampened.
Without the need of digging up the BT guide, I would visualize it says that if You must re-harmony the throttles, you'll want to screw each of the by-pass screws every one of the way closed, and then open up the screws within the a few decreased flowing throttles to match the best flowing throttle. This only getting completed In the end four throttles have already been modified to shut completely.
I did use the injectors plugs within the new harness, assumed they ended up only a little bit unique and i liked to maintain the OEM entire body to the injectors plug harness.
This really is just the strategy I made use of, I'm a good ass thats the one basis for it. if I had the money I possibly would have thrown it in the direction of the T3 item.
When the 1st harness is full Ii will take a look at viewing how It will likely be to construct a single from scratch working with junkyard sourced plugs and an AE102 harness(also are going to be including cars and trucks to have the plugs from, together with components)
That website Component of me is kind of dieing away and i am wanting to see what this motor vehicle is often like in its stock glory. I'm thinking a thing alongside the strains of the for my 87:
This not simply raises the airspeed which leads to much better cylinder filling, but due to asymmetrical airflow a swirl is established from the combustion chamber, which means much better gasoline atomization. This enabled the torque curve to nevertheless be intact at reduced engine speeds, enabling for better general performance over the whole pace band along with a wide, flat torque curve within the crossover level.[27] Throughout mounting engine speed, a slight lurch can arise in the crossover place and a qualified driver can detect the change in overall performance. Manufacture of the first-era engine design lasted right until Could 1987.
The 4A-FE differs from the 4A-GE concerning effectiveness and electricity. While each hold the same displacement and they are DOHC, they have been optimized for various uses. The initial apparent variance will be the valves, the engine's consumption and exhaust valves were being put 22.three° aside (in comparison to 50° inside the G-Engines). The second is it utilized Toyota's Large-Mecha Twin Cam technique,[18] where each camshafts are geared together with a singular timing belt driving the exhaust camshaft and also the exhaust camshaft drives the inlet camshaft via scissor gears (both camshafts on the G-Engine are pushed because of the timing belts as a substitute).[20] Some of the less instantly seen variances had been compact combustion chamber layouts with seriously shrouded valves, a lot less intense camshaft profiles, a Forged crankshaft (rather then a solid crankshaft inside the 4A-GE), ports of a little cross sectional space, a very restrictive ingestion manifold with extended runners joined to a small displacement plenum and other variations.
