Hi,

I have two SC400s (non-VVTi motor) and a S13 with a 1UZ swap (also non-VVTi motor). I am currently working on installing a VVTi motor with a 5 speed Nissan box into a SC400 track car.

I made the mistake of purchasing a JDM 1UZ VVTi motor about 4 months ago from eBay. According to the ECU code the engine came out of a 2002 Toyota Crown Majesta.

I am looking for some assistance in several areas:

#1 - I need the ECU wiring diagram. Does anyone know what US Lexus or Toyota closely resembles the ECU setup and wiring used on this motor? (this may answer below questions also).

#2 - The coils that came on the motor cross reference to a 2002 or newer SC430. I need to swap the 4-pin plugs over to the style used on the SC400 coils (I already have the coils, not returnable). Anyone know if the wiring is the same on the plugs?

#3 - Engine did not come with a ICM or MAF. Can I use the ICM and MAF from a US VVTi motor?

Thanks for any help.

The GS400 sub-forum tends to have more 1UZ VVTi talk and experience, last I checked.

Thanks.

Is there a way to move a post or do I re-post? Have not been a part of a forum in ages...

A moderator can probably merge and/or close it for you, but in the meantime, I would just re-post there and post a link to that thread in this one so there's no redundancy.
