I will try to get some info up tomorrow, but right now I am working on about 2hrs sleep for the past 2 days. I think I am going to try to use the G54 that I have now because it has been shortened. I am not sure if I have time to do all this with a R151 now. I will most likely need a bell housing for the 1kzt an flywheel and clutch assy. I will have to make it fit the G54 so I can keep the driveline the way it is now. Maybe even just a G54 bellhousing, but defiantly a flywheel to fit the 1KZTE.
Once I get it off the trailer and in the back yard I will be able to get more info.
Thanks guys and Zappel for your help, it is much appreciated.
