what cams?

[RobAce]

hi tech bods,

i am looking at upgrading my cams and pulleys i am thinking hks?

i have got a j-spec auto and am in the process of fitting a BL t-61, i am using an e-manage ultimate with a 3 row greddy fmic, i have modified the fuel rail for twin feed and upgraded the fuel pipe, pump and filter.

wot do you think?..... wot size?....

Most people seem to go for the staggered HKS 256in/264ex cams. But then i have the 264in/264ex, seem ok to me.
Dont bother with the HKS pulleys though, been reports of them failing. Stick with the stock ones.

I've had my HKS cam pulleys on for over 6 years and they were absolutely fine when I checked a few weeks ago.

Rob, I'd go in256/ex264, this should give you more in the mid to top end.

I think its also been dyno proved that the stock timing gives the best results.

Do a search as this has been talked about a few times before :)

HKS cams are very good as are Jun but V. expensive....Pulleys are not worth bothering with in my opinion.....wont give a massive power gain if any stick with the stock ones. + have heard the HKS ones chafe the shit out the belt....although some have had them and have had no probs wiv em, your decision :nyah:

thanks guys

I wouldn't/haven't bothered with pullies either mate. Especially as I actually know at least two people that have personally had them fail. (wear out with potentally disasterous results, although I believe HKS have redone these now).

I was one of the people who had the HKS pulleys strip the cam belt teeth - never again. In hindsight, I would also question why I, or anyone else, bothers to fit adjustable pulleys. I never thought of adjusting them and I would assume most people would be the same - so what's the point? :shrug:

Yeah I was the other. Also when we had the purple car engine on the engine dyno we found the stock cam settings the best compromise.

256/264 on that car too. Good for a road combination.
