Engine Identification

[skylinecouple]

I had to buy a new engine a while ago and found a motor with a genuine 32,000km.It looks like a R33 but has the smooth black CAS.This means the CAS drive is also different but thats all.The inlet manifold has the extra barb at the front of it as the R34 does but it also has the metal timing belt cover unlike the plastic one on the R34. It isn`t a Stagea obviously as it didn`t come with 4wd sump.Could it be a laurel or cima? The problem is I`m concerned the cams may be different as I still can`t put more than 15deg. into it at the top end.Have new injectors and GCG turbo and no restrictions anywhere as I custom made the dump pipe so even the waste gate is much bigger than anything you can buy on the shelf.

This motor is frustrating the crap out of me.216kws is not good enough.

the smooth black CAS is ER34 CAS so could be a neo 25 from r34 gtt

I`m reaching the limit of my computer inteligence to be on this amazing forum.But to give you an idea,I was at Bel Garage this afternoon and they couldn`t identify it either.Think of a series 2 R33GTST but with smooth round crank angle sensor in black.People I have been to are:croydon,advan,unique,race solutions and internet everywhere.

It runs great and crisp on the throttle with fantastic fuel consumption.I am ready to pull the cams out just to satisfy my own mind all is ok.I`ve heard the R34 doesn`t really go any different with cam gears but what if it has same cam specs as R33? Those cams have to go.Do I here 260deg Poncams?

Paul,the metal timing belt cover,have you seen an R34 with them?

late model r33s (1998) had r34 style CAS

it was a progression to the ER34 engine

so it should be a normal rb25det from an r33 but with ER34 CAS

That was my original thought as Nengun has cams for very late series 2.Must state when ordering.Timing is pissing me off though.
