Re: ITB Conversion on 16 valve 4AGE genuinely? probably i ought to have a new a person then? presently i get about 7.5L/100km for my really common ae92 SX? (about 450km's involving gas lights) i havn't had mine plugged in for more than six months due to the fact redoing the exhaust right before xmas! (snapped it off)
OEM 20V AE111 ECU (no, 16V unit can not be utilized for major requirement distinction within the four throttle Procedure and gasoline and timing maps, AE101 shown)
Exhaust flange with the AE86 header may be modified to suit the 20V. Though port destinations are precisely the same, but two of the retainer bolt holes need to have be moved.
You may "Incorporate To Cart" to protected the engine straight away, or fill the the form for almost any inquiries. Our staff will get back again for you Together with the relevant engine details in addition to a payment invoice!
8. Should you hear a knocking sounds on the engine, to be a rule It's really a wrist pin knock or you need to modify the valves.
On the exhaust facet, the valve is opened extended before the conclude of the ability stroke. In concept it would be nice to help keep the consumption and exhaust valve closed until the piston reaches the pretty finish of the power stroke to reap the benefits of every one of the force established through the combustion. In exercise, the little bit of burning gases which are left is just not truly worth fooling with Considering that the peak cylinder pressure is more than before the midway place from the stroke (discounting emissions).
Not essentially an O2 sensor fault there, but it was quite distinct that it experienced the potential to produce a decent effect on fuel economy depending on the way it unsuccessful. 7.5L/100km is a pretty damn superior figure nevertheless so Plainly within your circumstance it was not hurting the specific situation Substantially
VVT thrives to the substantial oil stress to move rapidly out and in of placement so in no way do nearly anything to drop the tension from the 20V.
From The straightforward 1.6L L4 4AFE to your 5.7L V8 3URFE, acquiring the proper engine for your Toyota or Lexus is easy. Regardless of if you are executing a direct swap or planning to insert some serious electrical power, JEGS has the ideal engine to your software.
You might be right over the assumptions. Understand that the collector has to be [[ open up at the end,]] for the right wave to return back again to The pinnacle. If dumped into an average exhaust technique you may need an growing place at the end of the collector that's 4 moments the quantity more info of a single cylinder […]
The following record is standard literature energy band information and facts for your 4AG naturally aspirated configuration. The knowledge is typical and supplies a good suggestion of Anything you can assume from the cams.
Toyota engines Use a status for trustworthiness and longevity, but even the most effective engines have to have replacement right after yrs of hard install. ATK Toyota crate engines are reverse engineered for being a lot better than new.
The one Resolution which has a OEM ECU would be the utilization of a 'remapped' 4A-GZE ECU, but this could also be void of VVT alerts. Probably considered one of my visitors will see a practical ECU to re-map in the approaching times. Until finally then, an aftermarket ECU is just how to go if 20V ECU is never to any avail... Aftermarket ECU is apparently over the record for some household-marketplace conversions. Motec, Tech II, Autronic are the greatly applied pcs which can be adapted with the 20V (while some lack Command outputs to the VVT) Some have the ability to memorize multiple map to help you have independent maps for various cams or distinct engine completely on precisely the same ECU. I have observed 1 pleasant instance in Japan which isn't promoted inside the United states of america. E&E Techniques' Flexibility CPU would make a 4A-GE specific Computer system which may Management any product 4A-GE such as the 4A-GZE and also the 20V, employing all of the factory sensors and accessories. (offered it's a Japanese ECU pin socket array). It could possibly memorize four personal engine specs so you're able to have just one placing for Road, a single for drag, one particular for keep track of and Yet one more for smog compliance...or a thing to that buy. The unit can also be totally programmable so you can mix and match factory sensors and ignition techniques. As an example, you can run 4A-GZE DLI ignition on a 20V applying force sensor from the MAP model 16V. Cool...certainly. Cost of this unit is about $1200.00 US so it's extremely fair as well.

Observe DLI ignition utilised through the 7M-GTE managed by Freedom ECU's DLI outputs.
