What difference would HKS 256 Cams make on a BPU Supra? Anyone got them fitted?

[Blackie]

Has anyone got these fitted? What difference would the make? Bhp or torque?

more of both i would say, but you would need some form of ECU control to adjust the map and timings? so i dont think its just a case of banging cams in and seeing gains

I would not fit aftermarket cams myself unless i was aiming for over 500bhp, i can see you only getting losses.

Any gains would be minimal at BPU level i would have thought. I wouldnt install new cams unless i was going single.

Wouldn't do shit unless you had a first decat........lol

you might be a bit quicker as you would of lost some weight

No just a standard ecu, I really dont want to go down that route of mapping and whatever, i thought they were plug and play sort of thing.

im just going to stick with what bpu brings, I thought the cams might add 20 hp quite easily but i wasent 100% on what they would do.

You're a funny guy Andy crack on, Its off on the 8th of Jan

you'd maybe make 20hp ontop of BPU if you changed your cam pulleys as well to adjustable ones and a good re-map to fine tune the timing. Alot of money for 20hp though.

I fitted HKS In256/Ex264 cams when running stock J-spec turbos at BPU. It gave a noticeable increase in power when the second turbo came on line and would pull to the rev limit. I also had an eManage fitted and the car dynoed at 429fwhp.

 

The cams on their own will only make a small difference, you really need a standalone or piggback ECU mapped to get the best out of the longer duration cams.

thats good peak power for a BPU+
