1UZ-FE VVTi into IS200

[whatthe?]

Yeah, do it Mos! I'll be there. A couple of IS200s rocking up to run some big numbers would be sweet

[whatthe?]

And here's some pics taken at Lindens at about 2pm Saturday afternoon. Shows just what an effort Linden and Mos put in to get it to Dyno Day on Sunday morning!

Goddamn, does a removable rad support make that easier or what!?

[The Witzl]

Hats off to Linden and Mos.
You've done well lads!

We have an X-trail. Auto and FBW. Very smooth and quick shifts (no hard thump into gears) on hard acceleration and soft almost indiscerable shifts when just slowly cruising. There doesn't seem to be any perceivable lag in input to actuation.

The problem with fly by wire throttles isn't the technology itself it's the protective management programming that they are usually controlled by. In something that doesn't make a heap of torque generally there won't be much done in the way of torque management and driveline protection.

The more torque the car makes the less directly connected the throttle pedal and butterfly are. It allows the engineers to program in specific opening rates to protect all of the components down stream of the engine in order to keep them in an optimal operating window, thereby reducing failures and waranty costs. You'll also find that a lot of tough cars with fly by wire throttles will stop allowing full throttle after a certain period of high load usage.

If you have a programmable controller that you can setup how you want it then in theory the fly by wire throttle, full fly by wire not the full cable plus motor setup on the 1UZ, should actually respond faster than a conventional setup.

Just read this whole thread - beginning to end and now my head hurts. What an awesome job dude - congrats on such a technical feat.

This here is my dream and will never ever ever start doing this sorta project, but let us know if/when this comes up for sale - even if its in 10 years.

Will follow with keen interest- kepe up the good work

One trick of FBW as used in some applications is that using a simple air density control loop the same pedal position can always correspond to the same manifold air density (and hence engine torque), so that exept for maybe near maximum power (at least for non turbo apps where ECU cant increase boost say) the engine will always make the same torque at the same pedal position. Also idle control can be done via the throttle valve since usually a special profile is machined into the throttle body to create a 'low gain' region where the throttle angle doesn't change the effective open area much..making it easier to delicately control airflow....

in case there was ever any doubt....

"yes, i wish to clarify, it is *actually* this big..."



i retract any erroneus statements as was made previously, it is NOT this big...

See it's growing. I must've answered some SPAM emails allowing for increased size. Now, I have your manifold and fuel rails here buddy! I'll post some pics of what I am able to do to them!

Mos - big credit to you, Linden and tuner dude for getting it happening!

The above pic not only shows penis size, but also the flange plate (with fist pipe) for 1 x Mos' header.

CRS Bellhousing.




On engine.


On engine and gearbox.


The bellhousing is supplied with a spacer plate for the clutch slave cylinder to clear a portion of the alloy sump. Due to the limited space between the passenger side header and the bellhousing, this spacer was discarded and the sump was clearanced (slightly) for the clutch slave.

Hmm, bellhousing has slightly changed design since I bought mine.

I ground a wee bit off the sump too, although I didn't have the option back then.

Shifter position with the MK4 Supra W58 with remote shifter and CRS bellhousing. Who would've thunk The A1 Turbos bellhousing is only mms taller, so the shifter position wouldn't change much.


Transmission crossmember adaptor. It's really more of an extender to drop the factory JZA80 isolator on the factory IS200 alloy crossmember. It also places the W58 at the correct height - ie the output shaft is at the same level as the auto output shaft.


Single piece tailshaft with larger, rebuildable unis. Luckily the F series diff flange is the same as the G series variant. The tailshaft sits only marginally lower at the centre bearing position, clearing the exhaust and everything else.

CRS Flywheel that has been slightly.. err.. "modified" to remove about 3kg making it a much more reasonable 7.8kg or so.

you weighed that bellhousing mos?! jeebuzz!
