| At this point I've decided NOT to get the whole throttle body unit from a different application but to use the existing TB and adapt a different TPS to it (or somewhere on the throttle linkage). I've acquired several used TPS's and am now mocking up a few variations along these lines to see what will work the best.
It looks as if 'jon' in post #3 is thinking the same thing.
I will (I swear) post pictures this weekend. |
