2jzte in toyota celsior/lexus ls400

[gach2]

hey
just wondering if anyones done or heard of anyone with
a lexus ls400 or toyota celsior
doing a 2jzte (i think thats what motors called, from a twin turbo supra)
conversion
if so would it be a lot of work to fit the motor in
as for wiring i can get that sorted
but more concerned with fitting and bolting the motor in
thanks

hey mate i dont kno any1 personally whos done it
but i recon it would fit sweet cause of the big engine bay from the v8
but good luk with it if u do it

[gach2]

cheers thanks for comment
well 1st aim is to have 200rwkw
which is probably acheivable with v8 4 litre with a supercharger
but also want to do a manual conversion
hence thinking to do full engine conversion
and though 2jzte as these will get 200rwkw without much work if any
and is a good base engine as i will probably want more power later

y not turbo the v8
but i recon 2j would b sweet

Manual conversion is where it gets messy.
The Celsior was never released manual, so there are no 'bolt in' parts (clutch pedal/bracket/etc).
Right where the clutch goes is the handbrake (foot operated), so that will have to be moved.

Bolting the engine in would be the easy part, wiring would be tedious, but once again, fairly easy.

I'd guess a lot of the Aristo JZS147 stuff would near bolt in.

celsiors are pretty heavy, mines nearly 1800kg. typically heavy cars need an abundance of nice easy torque to make them comfortable and easy to drive. V8's are made for the job, nice linear torque curve and peak torque available early. im not so sure about 2J's, sure they make the power but would they have to be on the noise considerably more often to move the celsior around with ease? 2J's are already pretty thirsty

also the enginebay is wide but not long, i just had a peek at mine, and with the rad and hydro fan setup you dont have heaps of room to be playing with up front. might have to get tricky with radiators. ive got a 1J out of the car atm i can measure that up and see if it'll fit alright if you like. 2J wont be much different in length

the UZ is a pretty sweet engine, expensive to modify but theyre tuffffff

isnt there an early 300 version with the na-2jz?

or am i thinking of the late model is300?

[CrUZida]

IS300 or GS300.

Celsior/LS400 body only ever came in one engine/gbox/driveline option. 1UZ, Auto, RWD.
Except for the Century, its probably the only other Toyota thats never had an engine/gbox option.

It has been done, a guy on the old Toymods forum had one. He imported it like that, beat me to it lol.

[CrUZida]

That would be Dr Love from memory

theres a supercharger kit for the 1uz available locally, unfortunately i cant remember which brand it is, but my best guess would be capa. with standard ECU, 7mgte and 8psi of boost the engine made 261rw/kw

sorry for the sketchy info but there is a kit(s) available. so it might be worth while looking into that option + mad respect for modifying a 1uz

[CrUZida]

Can you explain the 7mgte bit?

EDIT: also, nfw did someone make 261rwkw on a stock ecu @ 8psi...

[gach2]

thanks for the replies all you guys
i think gary makes a good point with the torque point
i guess i dont want to really rev the car for normal driving

in that case id like to ask about manual conversion for the 4 litre v8 engine
how difficult
how much id be looking at for this to be done etc

also with turboing a 1uz
would it be possible to get 3-400rwkw
even twin turboing
i know would require internals to be replaced etc
and i wont be thinkng about this for atleast another 18 months
but want to know if it is practically possible
without spending 50k on it

There are quite a few "member's rides" threads on cars with big power 1UZ build ups - Justen's GT8, Ed's 1UZ powered Supra, Mos' VVTi 1UZ powered IS200 and a Supercharged 1UZ Cressida (can't remember who owned it) come to mind... You should have a look through those to get an idea of the kind of time, money and effort required to make that kind of power output...

Having just been through the hassle of converting a 1UZ to manual, I'd suggest using an adaptor plate between the Auto bellhousing and gearbox, and also using a concentric release bearing... having a normal slave cylinder hanging out the side is a pain in the butt when it comes time to route your exhaust...

2jz-gte's turbo setup is quite torquey from down low and does not take much to get big power from.
Also, the Aristo/GS300 came as a JZS147 and a UZS147. i.e. Some Aristos came stock with 1UZ-FE (and AWD!)\
Have a look at e-tuner.com for a twin turbo (TD04) 1uzfe. Not bad, but not HUGE numbers.
