raptor 30 v2

[tgg]

what is the largest engine that can be fitted into the raptor 30 and what conversion needs to be carried out

[Stuart]

I don't know if they still do it, I'm sure they do. You should be able to get a .50 conversion kit still.

[kiwipilot]

.50 conversion kits are still available.

An O.S 37 without any alteration at all - put a MP2 pipe on it and you've loads of power.
