| Yes the frame is slightly different.
we have put my 748SP engine in a 748RS frame before and run it using the 748RS injection, although ideally a new map would be needed.
To do it this way you need to use the inlets off the R as well as the inlet rocker covers. An alternative would have been to use a airbox off a Foggy Rep (Kyalami Frame) and either 916 or 996 injectors and throttle bodies, harness, and ECU
engine mounting bolts are also different in diameter but sorted this with spacers usin the bolts from the 748.
to run the 748R engine in a 748 frame should not be to much of a problem, but it would be better to run the 916 injecion throttle bodies along with a 748 or 916 harness, 748/916 airbox, 748/916 inlet manifolds. You can use the 748R ECU fitted with the appropriate chip and I would suggest using the 748R's original 50mm exhaust system |
