Re: 929 throttle bodies on a 954
I got the 954 engine in my 929 yesterday, between the cali model 954 throttle bodies someone lent me and the 929 throttle bodies the 929 ones actually ran the best with 929 ecu and no remapping. also for anyone looking to do the engine swap themselves;
the 929 ecu/harness work fine with the 954 engine I think if I was going to use 954 throttle bodies I would switch the ecu/harness though. Two of the sensors had to be swapped from the 929 engine to the 954 do to wire lengths. other than that it bolted right up and ran decently with no remapping.
