Need new crank

[SupraDupra]

I need a crankshaft for my '88 N/A 7MGE Can't seem to find any ,just pistons and rods.Any help appreciated.

Also ,is there a reasonably priced alternative to the stock oil pump ,or some way to increase flow? I was reading something about "shimming" the oil pump for improved performance.Can anyone elaborate on this?

My rod bearings were in pretty bad shape ,and the crank bearings started de-laminating and caused intense scoring on the bearing surfaces.The crank is beyond machining and I would like any hints on how to avoid this problem in the future.

I had the same problem in the UK but managed to find two guys in the US that would supply a reconditioned crank at a reasonable price. I can only give you their contact info, as I found another used engine in the end to strip the crank out of, so didn’t need to buy from them. The quote below I received from Gavin.
1990 Supra Turbo 7MGTE engine parts:
TCK7M (Crankshaft with all bearings): US$270.00
2. TCR7M (Connecting Rod): US$38.00 per rod. US$228.00 for 6 connecting rods.
3. TOP7MS: (Oil Pump): US$155.00
4. TFS7MT (Complete Gasket set): US$77.50
5. TPR7MT: US$146.00 (Please make sure the size of piston and rings you will need, we have standard size, 0.020 inch oversize, and 0.040 inch oversize).

The Oil pump mod is as you said shim the spring to increase the pressure.There is a detailed link on the UK forum on this subject but the forum is down at the moment. Will post link as soon as its back up and running.

A few interesting links containing shimming and relocating of oil pump. You will need to page through the threads from start to finish to get the full contents; sorry I can’t recommend any of these mods, as I haven’t done them myself. How did you get on with finding a crankshaft?
