HKS Camshaft Problem

[Bullant47]

I have just had a set of HKS Step 1 Cams installed in my 94 Series 1 GTS-t. The exhaust cam is 264* P/N 2202-RN175. The problem is the CAS will not mate up to the HKS camshaft, with has a totally different arrangement to the stock camshaft. Has anyone experiecnced this problem and is there a HKS part that can replace the part that is riveted onto the CAS that engages in the camshaft?

Thanks in advance

so the cam has a star drive where as your cas has like a half circle drive?

R34 Cams have a totally different drive so you have 34 cams id say.

34 CAS works fine with a 33 ECU or 33 PFC etc so yeh if you can find one go for it.

Hi dnb. No its the other way around, the cam has like a half circle drive and my CAS has the star drive. But i think you understand my problem.

Thanks for your help dnb

Nooo...not yet dnb...far from it....I am going to try and locate a R34 CAS and that should solve the problem, but apparantly R34 CAS's are hard to locate. Didnt really need all this drama..If the right cams had have been sent to me from Japan, this should never have happened.

Thanks dnb

Yes the cams are installed along with new timing belt and tensioners, water pump, seals. Dont want to take them out and send them back to Japan..I'll have to find a way of getting the CAS to work.

Thats kinna odd isnt it? why would you have a star drive CAS? I thought all the non-neo RB25 had half circle drive?

I have a HKS 256 exhaust cam P/N 2202-RN171 and it has a half circle drive and my CAS is also half circle drive. So doesnt this mean you need to look for R33 CAS?

btw, Im also looking for a CAS as mine is stuffed

Stupid question....What is CAS?

[lukits01]

wow thats the 4th time today somebody asked me this, in 4 different threads

CAS: Crank Angle Sensor

used to determine ignition timing

I think its the opposite to what your saying lukits, the Series 1 and Early Series 2 have the star drive and the Late Series 2 and Neo R34 have the half circle drive in the CAS connection.

I have a Star Drive CAS working perfect for sale now. You can have it for $200 + postage.

Thanks lukits

Aggg I bought a brand new R34 CAS today and installed it and it appears to get no signal from and gives no signal to the Power FC...The starter just cranks over and the car doesnt even try to start. Help...Any suggestions?

Thanks in advance
