Thanks guys! We decided to pull the engine and trans and tear them down and do a little refreshing inside. The transmission is grinding and whining (I think the oil pump is dead and clutch material is roaming free inside. Since our budget is very tight, it will be a simple cleaning inside and out.
This is a 24 Hours of Lemons build, so it'll see quite a lot of racing and many many hours at full steam! We start removing the drivetrain this week. The first race is in February at Barber Motorsports park if any nearby members want to come and support.

The A340E that is in the car right now is not looking good. We pulled the valve body out and found massive amounts of metal shavings and sludge everywhere. I found a SC300 auto trans for $200 locally and wanted to see if it would bolt up. I assume they all use the A340E with the 2JZ GE?
Thanks

Yeah they all use the A340E, i'm not so auto trans friendly but I do believe the sc300 and gs300 have the same model year trans from 93-96

Yes the A340e from an SC will work you. You should also check out this link http://www.supraforums.com/forum/sho.../267655?page=1
Its a pretty long thread but the information is absolutely amazing. It includes simple and cheap things you can do to improve the shifting and power handling capabilities of the a340e trans!! I plan to do these mods in the next few weeks!!

Thanks guys. I am picking up a used A340E out of a SC tomorrow. Hoping this fixes the whirring and grinding sounds I am getting.
This is turning into a slow build since my other vehicles needs a little love

Did you check out the thread I posted a link to? If so do you think you will try the shimming modification? I plan to try it in a few weeks after my head gasket is finished.

So I went full retard and took the front part of the motor off to clean up the oil leaks and reseal. I flush the coolant system with water, like I do on my 5.5L V8 and Toyota 4.7L. Now it's misfiring and won't idle.
Shimming the cable body isn't priority one.
No engine = no racing.

Did you check if any water got into the spark plug valley/channel area. Years ago I flush/filled my radiator, and washed my motor after I just bought the car, and the seals on the spark plug cables for the motor were shot. water seeped into the spark plug channels and caused misfiring due to the spark shorting on the block. You may need to remove the throttle body to get full access to the spark plugs and their cables if I remember correctly.
Once I had the spark valley and spark plugs removed, I let them sit in the hot sun for a bit so all the water would evaporate.
I have a set of unused Denso? iridium plugs in boxes made for the turbo 2JZ. let me know if you need them. This is a budget build so I'll keep them cheap with shipping.

Yep. I blew coolant all over the top of the motor. I will pull the plugs tonight and turn over the motor once to blow anything out of the cylinders. Good catch! I probably let 2 cups of water into the valley and didn't think anything of it. I'm running cheaper plugs right now and seems to be down on power. Let me see if your idea is whats wrong and I'll PM you.
