I recently disassembled a GTE engine (6 spun bearings-wow!). Must have been a really bad tune or some other serious detonation issue (not my map).
I measured the pistons, and according to all year 2JZ-GTE service manuals, they are larger (diameter) than the GTE piston should be. The funny thing is that they all fall into the small end of range for the 2JZ-GE piston. Could someone have used N/A pistons in a GTE block? Is this possible. The measurements I took are listed below:
1. 3.3835
2. 3.3834
3. 3.3833
4. 3.3835
4. 3.3833
6. 3.3833
The limits for the GTE pistons are 3.3826-3.3830
The limits for the GE pistons are 3.3833-3.3837
I called Toyota and they don't think an oversized OE piston is available. All they have is part numbers. The Toyota I use does not know supras that well.
Does anyone some insite to share regarding this situation?
TIA!
