Life has me focusing more on real estate.... Motor & Tranny is FS!


Hey guys, I figured I'd start this thread to keep things interesting and maybe give/receive some insightful information. I havent started any real effort, just in the planning and design phases of understanding if this swap is realistically feasible. Financially, I have a number I want to stay under and I am well under that threshold with the parts I have already purchased:

`09 ISF 2URGSE complete with engine wiring harness, tranny harness, alternator, a/c comp and starter
`09 ISF 2URGSE ECU
`09 ISF AA80E transmission complete with all hardware to DS
`09 ISF AA80E ECU
`09 ISF complete intank fuel pump assembly
`09 ISF fuel sender unit (intank)
`09 ISF misc. relays, cut harness main engine fuse box
`PPE Headers

So whats this thread about?
Swapping a 2URGSE & AA80E into my 2006 Lexus IS350.
Why? Honestly, because I love my car and have too much money in it to ever get back selling/parting. Buying an ISF over my IS350 isnt for me. My WHP goal is 500 and that will NEVER be achieved on my current platform without serious time, very serious money and effort. I was close to doing a 3UZFE swap but if I were to use older hardware then why not just 2jzgte (which I did not want to do on this platform).

Feel free to comment and bring up questions, differences, etc. Anything that can spark ideas or thought would be much appreciated.

Sorry for the terrible pics...and yes, I need to clean!

12/4 Intank Fuel mechanism installed

Drastic differences between the IS350 (left) and IS-F (right) intank fuel units. Not a big surprise but the IS-F has a much larger fuel pump; its drastically wider in diameter. The housing is designed around the large pump and differs greatly from the ISx50. Same effective design just very different layout. It dropped right into the tank and I drove around to monitor stock functionality.









Around the engine outside of the ECU and Tranny ECU:

Differences:

Driveshaft - ISF is 2" shorter to account for longer AA80e.
Main room engine harness...the ISF has ACIS (vsv) for the secondary intake valve and a few other pieces parts. Soooo many of the wires are routed differently through the harness to account for differences including the AA80e.
Relays for ISF EFI (1 & 2)
Fuel pump (obtained from ISF)
Fuel Sender (obtained from ISF)
Fuel Line configuration and routing.

Main room harness is 82111:

12/21 - Subframe is identical (despite confirming part #s, nothing like proving first hand)

12/4 Fuel Sender confirmed match IS350 & IS-F
Installed a secondary intank fuel sender from the IS-F. Its a confirmed match though part numbers online varied. Stamped 53030. No difference at all...good sign:

Subscribed. Goodluck. Looking forward to seeing how this goes

 

Good luck on this build!

 

I wish you the best of luck! Its people like you that push the limit so that we one day might be able to tune our cars

Are you going to do an isf front conversion to fit the engine like a previous member who swapped in the 3UZ-FE 4.3 liter?

 

Mike, Stew mentioned this to me at Import face off. First off just wanted to say good luck I'm sure this project will turn out great. 2nd its good to see a fellow ohioan make this type of impact on the forums. Good luck with the build bro

 

Thanks man much appreciated!!


Thanks everyone
And no, hoping not to. I think Paulo did that mainly for looks. The 3uzfe should have fit....When I get to fitting the engine I'll know for sure but rough surface measurements are promising.

 

This is awesome! Love the idea, and love the fact you can't give up your current car. That means you really put the time and effort in to make it yours, can't wait to see the results!!

 

hahaha you are a performance maniac, I love it. Can't wait for the result

Can I fly you down here to SoCal to do this swap on my IS250?

 

I was wondering what that WTB for ISF headers was about... Lol

Good luck to you. Glad to see the forum shift away from asking "whyyyy" every time someone goes outside the box and now encourages it.

 

GL!! Can't wait to see it..
