What do you mean you cant find the right one?

Piper cams
kent
schrick to name a few.

I'm guessing your referring to the duration & lift?

I'm guessing he wants the best cam for standardish engine?
So what is best as just a cam upgrade with no other mods?
A wild cam won't work unless the head can breath, etc.

I can't say what to use as I have no experience in them

I ran a Kent GS23H which was a 285 degree cam and 11.53mm lift. It's jsut about the biggest cam you can fit without the lobe interfering with the head.

MPG dropped when booting it obviously, but when driving carefully it was about the same.

Idle was very lumpy, sounded awesome.

138hp from the 8v, that was with airbox modifications, pipercross panel filter and cat back exhaust.

Was the 'lumpy' idle tolerable for a daily and is it a straight swap?

It drive just as well on the road, no kangarooing. You get used to it quickly, and within a few miles you pull away smoothly and without kangarooing. And yes, straight swap.

Would you recommend a full head rebuild at the same time?
Title: Re: gti 8v camshaft?
Post by: Khare on 09 July 2012, 20:57
If you don't need it, then no. New tappets are a good shout though, as the old ones will be worn to the old cam, and as soon as you chuck a higher lift cam on they can give up soon.

Throw on a light flywheel and it will bark

I must admit i like this more 'organic' tuning but i'm guessing its not a cheap option.
**Just priced it up at about £300 for the cam and new tappets although the TSR website says should be used with 'modified injection'?

ive got a light & ballanced flywheel fitted and i noticed a bit of a diffrence (does rev alot quicker) and on my way to the gti show with mad4vws, he was driving a mk3 diesel i kept leaving him behind. As soon as we foot it he just started to fall behind. I also have a decat straight through zorst lol. So thinking about the cams and MIGHT port & polish the head aswel.
Mine barks & pops like a B1TCH! And when it pops it farking pops like popcorn esp when im slowing down and revs are just over 2k

Put the money towards an ABF conversion, trying to make a 8v quicker is not easy plus will or could in the end cost more,

So £274 for cam + lifters. Add a few more pounds on that for a new cam cover gasket. So about £280 all in.

Tis very true. The 16v in standard form is much better than a modified 8v, end of story, I know it well enough.

My problem is I ain't got the heart to pull out my 33,000 8v engine for something faster/better with more miles on it. Seems a shame and waste to pull it out.
I could of had a 2.8 24v in there by now if I didn't think that  :undecided:

theres a guy on club GTi (martin hot golf) he did mine. I think mine was 5.6kgs (there about) he lightened it to 3.2kgs (i think) but i have also been told that i should have got my clutch ballanced aswel. As when on biting point, sometimes the car judders & i know its the clutch thats doing that. He charged me just under 90 as i wanted next day delivery.

I keep looking around at cams as my cambelt needs doing soon, ive already got a miltek cat back and a k&n panel filter.
Newman cams seem to be the cheapest at about £160 for a 268 or 272, they are used in the mk2 championship so must be fairly decent.

You cannot balance a clutch as such, if you have a judder it is a faulty clutch or engine mounting in trouble.
