So i have a 1.6 and have heard a camshaft upgrade will do it the world of good. Could anybody tell me what exactly this upgrade will do to my performance, fuel economy and how difficult it is to do?
-
I have the same question mate so will watch on :wink:

You will get a slight increase in power further up the rev band in return for a loss of torque low down and a lumpy tick over if a fast road cam, but you will need to do other intake, head and exhaust mods to get max benefit. Its actually quite easy to do especially if your changing the belt anyway, which you must do.
-
fast road cams dont really make the tickover lumpy, only the cams with a lot of overlap get lumpy

A 270 duration cam is the max reccomended for everyday road use and will give you a bit of a lumpy tickover but a 255 also classed fast road will give you a smooth tickover.

I was just thinking of a gti one or a 1.8 one. what cambelt should i get???. Also what manifold etc would i require???
-
{ 266 / 270 / 272 } all pritty much the same cam TBH , all very tame and they idel almost like a stock cam in an 8 valve.
at 285 they get noticable, very flat to 2.5 / 3 then they take off ans the idel has got a bit rough. the rough idel everyone things about associated with cams is the the 290 - 305 cams they idel fast and ROUGH

So what would be the ideal parts i should really buy,I am planning a vr6 upgrade buy funds are tight right now.If anyone has any bits let me know :wink:
-
Just an 8v cam will do. I think Khare Bear got an extra 5hp or sommat (inc the other mods he made too?).
The cam belt will be the same as the GTI cam belt which coincidently is the same as the 1.6 Driver cam belt :wink: (all 8v Golf MK2s have the same cam belt iirc) oh and the tensioner is the same too.
-
Cheers ill keep my eye out for a cam. any other things which might improve things
-
If you are going to change the cam, then get new tappets too, to decrease the likelyhood of premature cam wear due to used and worn existing tappets. :wink:
-
A cam will help but unless you have done other mods the gain if any will be small.
-
what other mods do you suggest??
-
Stick a PB (GTI) head on it.
Put a 4-branch manifold on it.
Give it a little dose of porting.
Throw it all away and put an ABF or similar in it, because it runs like a bag of nails and is a pain to drive anything but flat-out.
