    Work involved to fit a fast road cam?

    Do i just unbolt cam and change lifters and bolt the new cam in and then re time it up ect.... or is there more work involved i.e measuring the endfloat of the cam ect.... Anyone shed any info on this ill appreciate it, thinking of fitting a fast raod cam in my 1.6 8v, has anyone done this before?

    cheers

    I'd have assumed it was fitted as you say - generally there will be some cam lube supplied to use exactly as the supplier of the cam says. Most advise running the engine at 2000-2500rpm for 20-30 minutes after fitting, with no idling at all, as this beds the cam in and (against initial thoughts) the valve train load is actually lower at this rpm than it is at idle.

    Its a easy enough job then, its only one cam, obviously i would change the water pump and cambelt whilst im there, im thinking of just getting a whole head from a scrap yard, then sending it to the guy at auto sprint and he can full port and polish it and then i just have to change the head gasket and time it up.

    500 quid but would see some decent gains from that and a remap?

    How much is the head work alone out of interest?

    You could see 10% bhp/torque and a little economy from the head improvements, perhaps another 5% from the cam or thereabouts.

    I think including the cam and head work it totals to around 550, then a remap to get the best out of it, so 750 odd. I know everyone will say get a z20let ect... but ive never seen this done before so i thought i would see if its possible.
    10bhp from the cam apparently, not sure about the head work but all together should see well over the 100bhp from a 8v engine.

    Spoke to a guy at autosprints on the phone earlier, said give him a call back on monday as he had just left the office, but he gave me a price of 550 for a polished and ported head and fast road cam. So thought id get a head and cam from a scrappy, send it to him, for him to work his magic on then all i gotta do is fit the head. Dunno how much power id see from it, but if i could see anywhere near 120 with a remap id be more than happy. Just want to be different i know its not everyone cup of tea, but imo its worth a punt.

    Gonna have a chat to the chap at autosprite tomoro about what sort of gains i would get from different head work and how much it would be, if i think the gains would be worth it compairing to the price, i think im gonna go for it. wish me luck.
