The twenty-Valve engines never ever arrived officially into your US (and a number of other foreign markets where by the previous 4AGEs were out there- and of course it imparts an exceedingly exotic existence. The individual throttle bodies seem like they arrived from the wonderful 503 race engines. Think it over, no Toyota factory RACE Engine experienced five valves for each cylinder!
If out there more recent rods with The larger wrist pin have to be utilized- Along with the later on design superior compression pistons. Clean up the ports and EGR passages concurrently. Validate crank pin measurements because there are actually discrepancies.
The sole Answer with a OEM ECU would be the usage of a 'remapped' 4A-GZE ECU, but this can also be void of VVT alerts. Most likely considered one of my viewers will discover a practical ECU to re-map in the approaching days. Right up until then, an aftermarket ECU is the best way to go if 20V ECU is to not any avail... Aftermarket ECU seems to be around the list for some residence-market place conversions. Motec, Tech II, Autronic are classified as the broadly employed desktops which can be tailored for that 20V (nevertheless some deficiency Handle outputs for your VVT) Some have the opportunity to memorize more than one map in order to have separate maps for various cams or diverse engine entirely on the same ECU.

E&E Units' Independence CPU can make a 4A-GE distinct computer that may Manage any design 4A-GE including the 4A-GZE plus the 20V, using the entire manufacturing unit sensors and components. (supplied it's got a Japanese ECU pin socket array). It may possibly memorize four individual engine specifications to help you have one location for street, 1 for drag, one for track and Yet one more for smog compliance...or anything to that get. The device is also completely programmable in order to combine and match manufacturing facility sensors and ignition units. Such as, you can operate 4A-GZE DLI ignition on a 20V making use of force sensor from the MAP design 16V. Interesting...certainly. Cost of this unit is about $1200.00 US so it's extremely affordable at the same time.

Quite pleased with selling price secured and repair presented. I didn’t have to go away property and offered my engine headache free of charge for a better price tag than rival firm.
VVT thrives on the superior oil force to move rapidly in and out of place so by no means do everything to drop the strain inside the 20V.
Nothing at all bad way too say, And that i’m way too lazy much too publish a propa assessment but if you try this assistance you received’t regret it.
Among the speediest shipping instances for international buyers. So far as I’m involved Craig and the fellows at JJH are the absolute drop by’s for all my 4AGE rebuild projects.
The rods are possible failures also when subjected to actual 4AG RPM operation. It is an exercise in creative imagination but a total sidestep for just about any authentic performance-oriented software. If you want the torque with the 7AF, use the complete engine.
