Re: ITB Conversion on 16 valve 4AGE seriously? possibly i should really get a new a single then? at the moment i get about 7.5L/100km for my fairly standard ae92 SX? (around 450km's amongst fuel lights) i havn't had mine plugged in for more than 6 months because redoing the exhaust before xmas! (snapped it off)
All our Particular person Throttle bodies are actionned by cable and you might be required to transform your pedal and mechanism if applying EThrottle. Modification on your own accelerator cable could possibly be necessary in certain scenario.
Thanks for your assist fellas. I'm scheduling on carrying out many of the perform myself hopefully. Has everyone carried out the conversion themselfs and when so could you bear in mind a tough estimate of how much it Value, just in pieces (no labour)
Not automatically an O2 sensor fault there, but it was quite clear that it experienced the potential to make a decent impact on gasoline economic climate dependant upon how it failed. seven.5L/100km is a reasonably damn fantastic figure even though so Obviously inside your case it was not hurting the problem Considerably
When both engines characteristic a thick gasket/heat insulator amongst The pinnacle as well as inlet manifold the Blacktop and apparently the later Silvertop models attribute a trapezoid Reduce-out as an alternative to a sq. Slice-out in provision with the gasoline route out with the injector.
i remember taking a picture of a lift gauge i attached to the vacuum block, i'll see if i can find it as i are unable to keep in mind what it go through, And that i also throew a mates vast band logger on there to check AFR's and MAP. I've a couple of display shots of portion throttle, and WOT.
You will need the correct crimping tools for all terminals that you are dealing with as well as an knowing on proper splicing methods and so on.
The initial-technology 4A-GE is nicknamed the "bigport" engine since it had consumption ports of an exceptionally huge cross-sectional region. Even though the port cross-portion was suitable for an exceedingly remarkably modified engine at quite significant engine speeds, it caused a considerable fall in reduced-close torque mainly because of the reduced air speeds at All those rpm. To get more info compensate for your diminished air velocity, the very first-era engines involved the T-VIS function, during which twin consumption runners are equipped with butterfly valves that opened at close to four,two hundred rpm. The outcome is the fact that at decrease rpm (if the airspeed would Ordinarily be gradual) 4 with the 8 runners are shut, which forces the engine to draw in all its air by way of 50 percent the runners during the manifold.
That is a Particular order item- They will have to be purchased with our provider and could possibly have an extended guide time. Also, if you end up picking to terminate this item just after purchase, a fifteen% logistical price might be deducted through the refund.
.. Even so many other styles are catered for and welcome to the workshop. The business is found in the S.E Suburbs of Victoria/Australia on the other hand a around the world mail services is out there.
With regards to Toyota technology, the dual versions of your twenty-valve engine- out specified any prior offering in The natural way aspirated sort. This is actually the last genuine iron block with the last word head design and consumption set-up.
The left flywheel pictured is the sooner Silvertop design and style while the ideal would be the lightened Blacktop.
Also the opening from the Blacktop inlet ports are about 4 to 5mm wider at their entrance about the Silvertop supplying a larger cross sectional spot.
Supercharger / Turbo Up grade- The planning for your turbo established-up will be to decreased the compression. The 4AG / 4AGZ that may see boosts in extra of ten psi really should be set-up with cast pistons. Blocks Along with the oil squirters have to be utilized as these have the higher rods. For boosts greater than eighteen psi, the rods must get replaced.
