rb25 cams

[240slidekat]

can someone confirm that the only difference between the rb25 series 1 and 2 camshaft is the CAS key?

im in process of rebuilding another engine, my previous one is a series 1. so im going to use everything i have in the series 1 (harness, ignition, greddy manifold, aem ecu, etc) and transfer it to the series 2.

so if anyone can think of any problem i might run into, ill be happy to hear it. thanks

[eh?]

Only the late late S2 has a different P/n exhaust cam.

so is it a different part number but same part other than the cas key?

intake cam should be the same, correct?

i believe they have different part numbers due to the difference of the cas key, it it were the same part # then it would be a game of roulette in which cam you would recieve. most aftermarket cams have S1 or S2 part numbers.
