Lexus IS250 to 3UZ-FE (completed)

[George_R]

Two recent projects of mine, 3UZ-FE 6a/t to IS250

Both of them feature fully functional instrument panel, a/c , push start and most importantly TRC & VSC systems. Other key things to mention are stock looks both inside and outside, clean wiring etc

Well done George! I'll bet that IS250 surprises a LOT of people

 

[George_R]

Thank you! I hope to try 1ur-fse in an is250 some day

 

[cribbj]

I wish you or Gloverman would try it and see if those monster UR's would fit in the newer models.

 

[George_R]

They will absolutely fit because IS-F exists
It's only about finding someone with enough funds =)

Way to channel the old Rod Millen IS430 spirit! Killer job.

 

[Kaktus]

Nice job, looks great!

 

[George_R]

Thanks! I wish I will improve these two cars and further conversions by tuning a/t in addition to engine. Goal is high 5's

 

[Kaktus]

That sounds very exciting, George! Let us know how you get on with all your further mods.

 

[Lilkirk02]

Thank god! I have a blown is350 and am looking to do this. Do you have a build thread?

 

[George_R]

Nope. This is result only. Proper variant of 3uz almost bolts up, real problems only start when you get to CAN bus partial incompatibility. But it's useless to explain in a place where most of visitors can't even read wiring diagrams. I could have posted nuclear physics articles with same negative result.

 

[George_R]

Updates
0-100kmh in 5.7 sec , with all interior and things
TRC off
stock ecu
engine tune stage 1
a/t tune is factory yet

 

[Kaktus]

Nice one, George!!

 

[George_R]

Thanks! I plan to slightly improve upon the result keeping all stock internals. Will report.

 

[Kaktus]

That sounds intriguing George, look forward to reading about that!

Btw, would you (or anyone else) have any measurements on the 3uzfe’s dimensions, such as width, height and so on? Haven’t found any online, unfortunately. This mainly to ensure it would actually fit into the Stag’s engine bay. Thanks!

 

[George_R]

Don't think so. I meah I saw nonvvti engine rough measurements the other day but I didn't care much and don't remember the place. You may try google photo search

 

[Kaktus]

Yeah, I’ve found measurements of sorts of the 1uz online, but the 3uz is not so easy. Probably no big difference though, mostly interested in the length of the oil sump to see if it’ll fit behind the front crossmember without modification or not. Will do some further searches to see if I can find something useful.

[Kaktus]

Thank you!

I assume the oil sump for the 3uz is pretty similar in shape and length, but in the back end of the engine instead, right?

 

[gloverman]

Kaktus maybe start a new thread instead of high jacking georges one. Ill flick you a 3uz sump photo when i get a chance to take one.
