For no explicable explanation the timing marks / notch on the Blacktop engines are half a tooth / 10 degrees far more clockwise than a Silvertop.
The only real solution using a OEM ECU will be the use of a 'remapped' 4A-GZE ECU, but this may also be void of VVT signals. Maybe certainly one of my visitors will discover a feasible ECU to re-map in the approaching times. Till then, an aftermarket ECU is just how to go if 20V ECU is never to any avail... Aftermarket ECU seems to be within the record for most house-industry conversions. Motec, Tech II, Autronic are classified as the broadly utilised computer systems which can be adapted for your 20V (while some deficiency Regulate outputs for that VVT) Some have a chance to memorize more than one map in order to have individual maps for various cams or distinctive engine completely on the identical ECU. I have seen 1 awesome example in Japan which is not marketed in the United states of america. E&E Programs' Flexibility CPU helps make a 4A-GE precise Computer system which often can Regulate any design 4A-GE including the 4A-GZE along with the 20V, working with all the manufacturing facility sensors and accessories. (supplied it's got a Japanese ECU pin socket array). It may memorize 4 unique engine specifications so that you can have a person location for Road, 1 for drag, a person for monitor and yet another for smog compliance...or a little something to that get. The device is additionally entirely programmable in order to blend and match manufacturing unit sensors and ignition methods. For instance, you can operate 4A-GZE DLI ignition on the 20V using force sensor from the MAP model 16V. Awesome...in truth. Cost of this device is about $1200.00 US so it's totally sensible in addition.

Then There may be longevity and driveability. You could possibly create a 250 CHP NA or 800 HP turbo motor but that doesn't necessarily mean It will likely be most effective suited to the aims. The NA will likely be peaky, the turbo will likely be laggy. both of those will sacrifice a lot of reliability for that efficiency. For most of us a 180 WHP NA or 250 WHP turbo could be a lot improved.
Despite Other individuals claim of a 20HP or more improve- on modified heads on your own, this is actually impossible with out camshaft or pistons transformed. Toyota has casted and machined all their 4 valve heads to incredibly shut and exact tolerances for Road (and rally) use.
To take care of a similar position / offset of the key crank pulleys interior row with it’s the wider belt / travel pulley There may be 1.7mm less of the offset in the rear Centre confront to the internal row Using the Blacktop. See decreased for conversion notes.
Normally the belts can’t be swapped in between engines but if the complete tensioning technique (16V / Silvertop: Oil pump, spring tensioner and tensioner put up fitted to block) is improved / equipped then a Silvertop belt can be used on a Blacktop.
I am curious so far as the so far as the twin turbod in the Toyota Tundra,Exactly what are the shortcomings…
The 20-Valve engines never ever arrived formally into your US (and many other overseas markets the place the aged 4AGEs were accessible- and of course it imparts a very exotic existence.

While each engines have round throttle blades, even so the Blacktop throttle blades are much larger at 45mm in comparison to the 43mm in the Silvertop.
Even with reviews of dissimilarities all 20V engines along with the later design 16V engines use a similar portion number to the crank.
