You can fit a stagea motor to an r33 but not the other way aroung, as the sump wont bolt on

cams are different

thanks guys, how differnt are the cams ? more duration ?

just had a look at a stagea mota 2 day, sumps look completly different, stagea sump has 12mms ? is it just a mater of re drilling the r33 sump to suit ? or have to mod the stagea sump to suit rwd ..

cams are different

stagea motors have the bolt patterns for both sumps so a 2wd sump will bolt on

AFAIK its only a theory - but one I agree with. stagea always seem to be 20% down on power compared to equiavlent gtst even when run in 2wd. Might put up my hard earned and get my old stagea cams measured.

so you can bolt a GTST sump on with no mods?? not like a rb26 where u have to do some serious mods to sump...

Series 1 stags are R33 engines, series 2 (much much better) are neo engined and not slugs.

I have my series 2 stagea cams sitting in the shed somewhere too. There was definitely an improvement going to 260 deg type B poncams but the jump was consistent with any other neo engine so (without measuring them and actually being sure) I think they are the same as an R34.

I might add that I was firmly in the camp that thought the cams were different based on the issues we had making power and probably was one of the people that started the whisper campaign.

The engine behaved like a few other neo's out there that are possessed by demons.
