I have to choose between Cams or head work on my up coming head removal...

I cant afford both (end of story).


So what would you guys do?
And why?

What is the extent of the head work you want to do??

cams... been proven with the CA18 head that you don't gain too much by the normal polish & flow...

on the trick side, I also heard that you won't benefit from cams under XXXhp with the CA18 motor...

sounds sexxxy!!!!

i also say go for cams!

head is quite well cast from factory apparently!!!

Full head work...

Bowl Work, Combustion chamber, CC', Polish of combustion chamber and Exhaust ports.

Cutting of valve guides... Bla , bla, bla..



Cam Cut will be around 9.5 lift and 264 Degree

I would go for head work then, but then full head work which includes lighter valves etc. The cams can be put it at a later date with out removing the head, the head work cant. Also an intake manifold would go a miss.

As i understand doing cams on a turbo car is a big no no headwork go for gold cos cams only allow more air to enter and there for u have got the turbo headwork on aturbo is mutch more efective

Lighter valves no then you looking at R 4000, plus you will need to convert to solid lifter just to get really any gains.

Nope not Really, Maybe a genuine set of tommi cams or billets, But I have phone around 30 place's looking for billet cams and I still can find . Tommi you looking at around R 6000 - R 8000 a set imported.

Also an intake manifold would go a miss.

I would love to do an intake, I have something in the pipe line that I hope works out, But I need to use the extra flow plus the is a big drop in low range torque...

Did I mention I'm on a budget around R 6000

Not Attaching you gary, Hope its cool

As i understand doing cams on a turbo car is a big no no

Agreed , But not 100% head work will gain but it has been proven over and over again that turbo car gain a lot from cams. As long as the exhaust / reversion pressure can be handled

Lighter valves no then you looking at R 4000, plus you will need to convert to solid lifter just to get really any gains.

Got confused cause you said

Cutting of valve guides... Bla , bla, bla..

What I meant was you dont have to take the head off to change cams so while the head is off I would do the head work.

This is what we need to know.

No Its not cool, you will never live this down hehe just kidding its all good.

Old wives tale.
A set of 264 deg cams will give you between 10 and 20kw gain. Full on head work maybe 5 to 10kw.

Cam's ftw everytime.

I say sell it and buy an Opel Dammit!

HUH ???

Cant you regrind the cams to 264, why do you want to go billet??

Cant use the stock cams On extended valves.

But What do you guys think of ARP head bolts

Cant use the stock cams On extended valves.

Extended valves?? Whats that??
