fitting a fast road cam

[steven240374]

Hi all i have been thinking about fitting a fast road cam and wondered if it would make a big difference or not i have a 1.8 ls and how difficult are they to fit and would i need anything else with it thanks in advance

possible you may need a vernier cam pulley to take full advantage. But fitting should be pretty easy...

Is it worth doing for the extra power or would i be better saving for a bigger engine

[Gaz]

Bigger engine really, thing is ive got piper cams in my cav and it loses a fair chunk of bottom end, its all at the top end now, which is fine while your playing but 90& of the time im driving it to work and i could do with the low down pull in traffic.

fit a 2.2 never heard of that in a cav...

Think I missed something here - can't see a post mentioning a 2.2

2.2 would be a Carlton or Omega engine wouldn't it?

I've toyed with fitting the z22se, but can't afford one. Would be a heck of alot of work.
To get the fully benefit of the cam you would have to fit a vernier. There are fast road cams sold by LMF, buy the time you get the full kit, your looking at £300 plus. some cams will pull the power band to 2500-5800. so you will loose a bit on the bottom of the rev range.

You could try a cam from another big block. I currently have a 18SE cav within the c18nz - this is due to it being cheap (£10 new ebay bargin) it appears to have improoved the torque, but then the old cam was rather worn - so it might be just me.

maybe a 2.0 8v cam?

i think the z22se is in astras, zafiras and vx220s.

2.2 Z22SE from an astra with gearbox went on ebay for under 300 quid this week. i was keeping an eye on it out of interest. if i'd have known i would have let you know gary

Cheers, couldn't afford it at the minute anyhow as from tomorrow I'm likely to be unemployed again.

oh dear thats not good maybe you should go into working on cavs for a living i,m sure we could all keep you busy

to be honest though, the 2.2 couldnt pull the skin of a banana so I wouldnt bother with them, a few mates had the 2.2 SRi astras and they were rather poor.

I never understand people wanting to spend money tuning the 1.8 engine, you can pick up a good 2.0 8v (SEH or the NE) with everything including the gearbox for pennies these days, its a dead simple swap aswell.

[steven240374]

i think thats the way i am going to go save some money and get the bigger engine

[Cavyman_130]

good plan mate, as said you can pick them up dead cheap these days.

[Squig]

There's a fair bit you could do cheaper to the 1.8 that you would be spending more on for the 2.0... eg cams from a 2.0... if you can find one a 1.8 mk1 astra gte head... but at the end of the day if cubic capacity is your wishes get a 3.0 v6.

[Cavyman_130]

there was a chap over on migweb selling a 2.0 8v SEH, 93k with history to back it up, everything going with it including the F16CR box, he wanted £100 for it, to be honest I cant see you getting gains from the 1.8 that will better the SEH for £100.
