Blown Headgasket Engine Swap Compatability [850xs70]

[erikv11]

Good general rules, and there are even a few more options. You can also interchange a stock 97-98 2.4 turbo (the GLT turbo; note the 96 and earlier the GLT was not turbo) with a stock 94-98 2.3 turbo (the T5), all you want. Keep the same turbo in place or use a T5 ECU if you are swapping a T5 engine into a GLT.

There is a break in the auto transmissions speed sensor setup between 95 and 96, with the way the speedo gets the signal. It is easy to fix but takes a little DIY of splicing wires, worth noting if you are talking about swapping auto transmissions between years.

Awesome, thank you!

If the '98 S70 is a N/A (non turbo) car it is the same engine and will bolt right up. The differences between the 850 and the 98 S/V series is cosmetic. Under the hood they are the same other than some fuse box refinements. Starting in '99 everything is dramatically different but the '98 will work fine.

Time to run some more VIN's! Fingers crossed its not turbo!
