Series 2 Cams In A Series 1 Rb25

[van-drift-line]

Hi guys, I recently put in tomei series 2 cams into my series 1 rb25. The cams are 256 duration and 8.5 lift. I swapped crank angle sensors and switched the trigger wires on the new CAS. The car still will not start up. Is there anything else I should check? Anyone else who has done this before? Advice?

Thanks,

Scott

umm, may i ask why you switched the trigger wires over?

I put an R34 engine with the same CAS in my R33 and had to get auto elect to change a wire. Trouble is, can't remember exactly which one. I know a friends track car has the same setup as mine and his was done by Croydon Race Developments. Give them a call.

I switched the trigger wires because I read on the forum that that was needed to get the car running. http://www.skylinesaustralia.com/forums/Rb...=r34+cas+on+r33 Its in post 11 and 12. As for calling Croydon, I live in Vancouver, Canada so it is a little tough for me. lol. Thanks though

ok, well in that thread it says that some series 2 cas' are the same as series 1 (and series 2 from before oct 97) so it might be worth swapping the wires back and seeing what happens

Ok, so It turns out the reason the car won't start is due to the CAS sending the firing order backwards. Anyone else experience this problem?

Weird. Oh wait, if water spins one way when it goes down the drain in the southern hemisphere and the opposite way in the northern hemisphere then it would seem logical CAS sensors would work the same way.

hahahaha maybe your right.
