original exhaust with piper 285 cams

[b4rks]

As above really, got an original mk2 8v gti exhaust coming tomorrow to replace the powrflow backbox that's on it at the moment.

Only concern is that when the cam was put in the engine may have been set up with the exaust in mind and it'll cause running problems.

I bought the old girl with the cams already fitted so I don't know?!

What do you reckon?

Plus what should I order to replace the cam with the orignal - is it just the camshaft or are there other bits? gaskets and stuff?

Sorry for being so novice and asking so many questions at the minute

Just trying to get it all back to original.

because of the duration of the cam it'll be flowing alot more air but the exhaust should cope with it, you may lose a bit of power as it struggles to get rid of the gasses but the exhausts are pretty efficient anyway. to remove the cam you'll need new tappets as the 285 ones are shallower to allow for the bigger lobes of the 285.

Joe,

Cheers fella, that's almost exactly what I was hoping to hear.  So worst case I'll just lose a bit of power until the time when I can get the standard cam back in?  Excellent.

This has got to be one of the most spot on forums on the net...... to everyone that's helped out so far, cheers

If you do whip the cam and the tappits out , will you be selling them? If so, first dibs!!

Absolutely pall...... got a slightly stained, but very noisey powerflow back box up for grabs if you're interested too......

The cam and associated bits was over £200 new, I'll see how well it runs with the exhaust back to standard, but they're more than likely coming out..... I'll let you know.

Is VW the best place to get an original cam and tappers would you think?

[Horney]

WHereabouts are you located?

Tappits can be got from VW but I suspect the cam is no longer available so second hand would be your best bet. You quite often get people breaking cars/engines on here so it shouldn't be too hard to get hold of one. Also check out ww.edition38.com as I'm sure there was a standard 8v cam for sale on there the other day.

I think you'll need a new cam pulley too as the one fitted to yours will be a non standard one to dial in the hot cam. Rather then havong to re dial it for a standard cam it would be easier to swap back to the standard pulley.

tappets are stupid money from vw! i think i got some from eurocarparts, under half the price! might as well change the rocker cover gasket too. watch out when retightening the cam caps they dont need much torque.

[b4rks]

New camshaft, pulley and tappets, rocket cover gasket - cool

So the next question is:

Anyone got an 8v standard cam for sale?

Horney - shame the magic cam fairies can't just swap ours over, would save a lot of trouble! (And I'm in Gloucester(ish), J13 of the M5)

[Horney]

Yeah that would be nice! I could come up to yours and do the swap but I have no idea how to tim eyour cam in on my car and I would need to do right to get me home!

So the only result is for you to move into my house, put your cam in my car then share my car?  I don't know if the mrs would go for it but i could ask!?
