It looks like I have found a donor LS-400. The car is a 1993 with 187,000 miles on it. It is a complete car that starts so I know it has all the hardware and wiring that I should need. This car was in a fairly minor crash, but since it crunched virtually every corner, the insurance company decided to total it out. It goes up for auction soon and my friend will bid on it for me.
Here are my questions.
1) Is there anything I need to look out for in a 1UZ with this kind of mileage? I plan to set the valve lash and install a new timing belt. What else should be done with the motor out of the car?
2) Should I hone it and re-ring it? Again, should I even bother pulling off the heads? I plan to run the motor basically stock, at least for a while. I might put on the JBA headers from a Tundra and a K&N filter and the exhaust will be free flowing with 2 CatCo 2.25 inch convertors into a "Y" pipe up to 2.5 inch through a DynoMax Ultra Flow Muffler. The muffler sounded great with my turboed 22RE pushing nearly 300 hp. I can't wait to hear the un-corked V-8.
3) I will be using the LS400 trans. Should it be freshened up? Replace fluid and filter. Anything else? I may be able to drive the LS before yanking the motor, so I will run the box through it's paces. Should I "shift kit" it?
4) Is anyone using a stock US 93 ECU? Do I have to conect anything to the TRAC / ABS connections of the ECU to make it happy?I will not have any wheel speed sensors, just the basic drive shaft rpm for the speedo/cruise.
5) Do the 93 LS-400's use a slip yoke or a flange at the output of the trans? I will have to make up a custom drive shaft and I don't know what I need just yet. The '83 IRS Celica has the back end of the drive shaft go through a hole in the rear cross member, so I have to make sure I can drop the front end of the drive shaft down to remove it. This may get tricky, or I will have to dop the rear end to put the shaft in or take it back out again.
6) I am fairly sure it is a 49 state car. How much will I have to change to make it a California spec motor? I know I will need to add the EGR system, is this just a bolt on or is the a difference in the heads or manifolds? Will I need to swap out the ECU to control it.
I am sure I will have alot more questions once I get the two cars together and start moving parts.
