Will an Injection pump and turbo from 90 fit 91.5?

[Deere Jon]

Can parts from these two engines swap? If so what is a long block worth, a man is wanting to buy my 90 engine I was going to use for a cummins conversion to make an alcahol bunning pulling tractor out of. Thanks Jon

Yes, they will interchange. Might not want to go backwards with the turbo though. The deliveryvalves will probably need to be changed as the two pumps employ different length valve holders.

The turbo from the 90 will have a smaller inlet and outlet on the compressor... and a smaller dia compressor wheel.

The rest will bolt up, but the fresh air plumbing will have to change.

As GL said it is a downgrade
