Swapping Cams?

[lukits01]

Can you use Exhaust cams for your Inlet?

I have a RB25 with HKS 256 8.8mm Exhaust cam and was thinking of purchasing the inlet cam to make the pair complete. Ive learnt that 264Ex and 256In is a great combination.

So was wondering if I could use the exhaust cam shaft on the inlet side (with VCT) and buy a 264 EX to replace that?

I know you cant use the inlet on exhaust because it doesnt have the end bit that connects to the CAS, but not sure about the other way around.

did you get a good gain from using the hks with the stock inlet?

yea like you said wouldnt fit because of the two differnt cam gear conections.

the tomie pon cam set up for a series 1 rb25 is 256 inlet 256 ex and people also get good resaults with that set up so i would try the 256 inlet with what ya got and if ya not happy sell the ex cam (to me) and get your 264.

Yea the 256s great

I can feel there's less lag with the stock turbo

pushed the car over 200rwKw too

So you're saying the exhaust cam wouldnt fit with the VCT?

im no expert but im pritty shore it wouldnt. ive had my cam gears off when i took the head off my car and they bolt to the cam completly differnt from ex to intake.

i dont know if the profile of a 256 ex cam is differnt to a 256 inlet.
