Should I fit a g revision DV.

Phew! I'm now confused but am kinda glad I have a Forge DV.

 No disrespect but I have some real bolloxxx with Forge DV's leaking. 

....No disrespect taken 

I guess I must have been lucky so far with my Forge DV. JKM fitted it in ~2006 (? - when they first became available) and they have checked it on a couple of occasions and also data log my car regularly.

Think your probably right stevo the d and the diaphragm type have completely different ends too them in shape so might not be sealing properly, I also have my n75 duty cycle up next to boost on the high line, the d barely registered more than 0.7 under normal driving half to 3/4 throttle and 700mb. The diaphragm shows n75 duty cycle at lower throttle and higher values yet builds boost quickly and can hold it to higher levels so maybe its a combination of the d type and the rest of the housing in the turbo not being matched and in the k04 with relocation the whole housing is different to work with the piston type.

All i know is that since changing back my car feels a lot more lively and fun to drive, im getting less lag and quicker pick up and the lift off noise is back for when i want to be childish!

Robin, is the forge one the same for ed30 as it is for gti?

any idea where i can find one of these?

There seems to be so much swapping and changing from G's to D's to G's again... would it not make sense to just buy the best quality part and fit it once  


edit: i just read the post regarding Forge ones failing

If you go to JKM's Facebook page you'll see a pic of the very latest OEM revision - It's neither 'D' or 'G'. A quick route is to click my sig > go to my Timeline page > click JKM in my Likes top 5.

....That's what I did by buying the Forge DV (first batch in ~2006) - No problems to date.

So where's this post about them failing, please? Statler's Steve isn't at all specific in his comment if that's what you are referring to.

Hmmm.... so its the D but without the cage!?

I wonder if they have replaced the plastic sealing ring with a rubber one then?

Wonder what part number it is too

[callis]

Right

Now i am seriously confused. 1 minute people are saying get a D as the G rubber falls to bits and VW are not doing them anymore....Now people are saying get the G cos the D isnt up to the task....

So which is it D or G?
Or does it simply depend on the year of your car?

[GarethB]

I think that it is best to summarise as:

Rev D - plastic piston, less prone to failure, may leak boost due to design

Rev G - rubber diaphram, could (will) tear/rip over time, but holds boost better.

And to add to the confusion I don't think the very latest one is either D or G. Ask JKM - They'll know because they have posted it on Facebook.

Someone has asked for the partno. on facebook... will post here when it's answered...

Statlers changed mine to a G, I have a stock of them just in case, lol!

My mate had this on his Scirroco... anyone else used it?

Ive got a G fitted, since 05 lol, so was going to fit a D as i have one, But now im think do i just replace it with another G?

[andrewparker]

I can't add any statistics but my car (KO3) felt a lot more lively with the original diaphragm DV, than it does not with the revision D, particularly around the top end where is just seems to run out of steam sooner.
