Title: VNT in MK2 / MK3 / B4 - Rear mount / turbo mods?
Post by: myke_w on September 25, 2009, 06:54:21 am
So I've been considering a vnt on my mk2 but I think I'll have to fight with the rear mount to make this work.

Has anybody come up with a good solid solution to the fitment problem mounting a VNT turbo (on a mk2/mk3/b4) this creates?

This is a GT1749VA turbo, clears the mk2/3 mounts perfectly! It's for sale BTW!

perfect condition, I took the housings off and the CHRA all looked good and play was minimal.

looks like the manifold was stood a while but i have a better one to go with the turbo

PM me an offer, I was wanting about £150 + Postage but i'm not greedy! i go on holiday at the weekend so want some ££, lol

Shipping would only be about £60 with the manifold, I have all the oil lines and turbo - engine brace with it too!

This mounts at the bottom but more inline with the ports, I'll get some pics fitted to the engine!

It's from a PD130 Passat, EU only i believe!

So - I assume you are saying this turbo fits in a mk2 chassis without modifications to the mount?

Doesn't look like it would- the manifold is a "hang down" type, I'd be willing to bet the inlet of the compressor is going to aim right at the rear engine mount.  I had the same problem on my MkII.  I have an ATP style manifold now, but I'm a little nervous as to weather or not it will clear the firewall now.  :P  Engine should be going in the car pretty soon.

Brendan - Mind snapping a pic of that manifold for us?

My original post was inquiring about turbo configurations that would fit a mk2 / mk3 / b4 chassis WITHOUT modification of parts.

I'm pretty sure the stock AHU / 1Z turbo setup is a drop in.

It fit's perfectly with no mods as it does not hang down like the Mk4 turbo's, I'll snap a pic now and post up when i upload it later!

Cool thanks! Please do. How is firewall clearance?

What's the going rate on one shipped to a London address??

Also - how many miles on it and can we see some closeups of the compressor wheel?

Thanks kindly!

Shipping within the UK is cheap and easy so i can do it for £160 with the oil lines too and a cleaner manifold.

I've not fitted the engine back into the car but these have been fitted before and it doesn't hang back much more than my 1x manifold, i had no worries about it fitting anyway! there is more clearance between that and my ibiza as standard!

If you want any more pics let me know! it's in V.good condition, not sure on the milage as i bought it off the shelf.

huh - so firewall clearance on say a mk2 golf wouldn't be an issue?

Are you saying £160 is just the shipping cost?




Title: Re: VNT in MK2 / MK3 / B4 - Rear mount / turbo mods?
Post by: ryanp on October 01, 2009, 06:48:33 am
£160 for the turbo, manifold and oil lines. Shipping will about £15 within the UK, if you want it direct to the US add another £50!

The turbo is about 1" past the rear mount so i dont think there will be anny problems! there would be a couple inches at least.

You've got my undivided attention now.

three last things - :) Sorry to be so particular.

1) Can you give me an idea of the radial and axial play on the turbo

2) Can you verify smooth vane / diaphragm function when vacuum is applied

3) Can you verify or picture document condition of impeller and compressor wheel fins (I'm not interested in a turbo that has any damage, and I really can't tell from your pics, close ups of each side would suit me)

Thanks in advance.

That does look like it would fit.  The ATP manifold I have sticks back farther- I'm also using a MUCH bigger turbo.  :)

I'll try to get those pics.  I took some a while ago, just been so busy I have not had time to upload them.

Though it looks like this one would work great.

I'll sort the close up pics ASAP

No radial play at all but slight axial as to be expected with a used turbo, the wheels dont come into contact with the housings either. With oil pressure this play would dissapear i imagine.

I've not applied vaccum to the actuator but the vanes move freely, I'll take the can off and check too! it should move with noting more than a slight knock!

Thanks for the quick reply -

consider it sold if it all checks out (fin condition), I'm anxious to see pics.

Update:  It fit.  BARELY!  I had to "massage" the passenger side brakeline a bit, and actually dropping the engine in was really close- literally jammed it in there- plus it would have been smart to keep the oil feed line detached until the engine was in place... but we are in good shape now!  Fabbing the downpipe will be an adventure.   ::)

So yeah, this turbo should fit with plenty of space.

It appears from all the data I can find that this is the same turbo that comes on the passat 2.0 TDI that we have have here in the states.

It also came on any longitudinal mounted 2000+ 130hp european passat tdi and maybe some pre 2000 A4's as best I can figure.

I think OEM part # should be 038145702 E/G/N

Can you confirm this Ryan?

Thanks
