I know this is more of a supraforums topic but i was hoping someone else on here might have ran into a similar issue with a 240/2JZ swap.
Id like to do the aristo 2JZGTE VVTI swap into a 98-05 lexus GS300.
From what I've read the Aristo/GS300 are virtually the same chassis and swapping the 2JZGTE is almost a total plug and play job with little to no modifications.
As far as build plans go i would do a single turbo setup on mild boost to keep it a nice daily driver. Id like to keep the motor pretty much stock minus a single turbo setup, piggyback tune, fuel rail/injectors and a bigger intake manifold and throttle body to smoothly move more air. There are plenty of choices of choosing a 2JZ intake manifold but they all seem to require using a cable driven throttle body with no plugs for factory sensors, as opposed to the drive by wire style unit on the factory VVTI throttle body from the aristo.
Since this would be a daily driver, retaining as many options as possible is the goal (cruise control, traction control, etc) Or trying to keep the car as "factory" as it could be. .. with no check engine lights at the end!
So the problem i have run into is trying to change the factory 2JZ VVTI intake manifold to a large plenum style with intake runners AND keep the cruise control, traction control, drive by wire, etc.. AND.. the new manifold would have to still have to have clearance in the GS300 body (IE: clearing the driver side strut tower)
I have a fabricator that could probably weld the VVTI throttle body to a different manifold, but that would still leave me with a 75mm throttle body which in my opinion, is way to small for any kind of single turbo/2JZ application. But that would be considered a last resort method..
Im not totally sure about this, but from what I have read the only way to retain the traction control/cruise control systems in this swap is to use the factory throttle body assembly that the motor was made with.. I didnt know if that was true or not so i wanted to seek public opinion.
any help would be appreciated, thank you!
NOTE: when I say VVTI throttle body, i am referring to the one that has the (ETCS-I) plate on the top of the throttle body.
