335 brake servo swap

Post Wed Apr 01, 2009 1:38 am

Hi has anyone changed the brake servo for a vw golf smaller one?

If so which one and problems encountered please as my one is too close (read rubbing) on inlet manifold!!!

Many thanks in advance

I'm using one from a Mk1 Golf GTI.

It's a straight swap, NO modification needed at all.

Pedal might be slightly firmer than it was but not enough to be a problem, in fact personally I prefer it.

Ta - have been looking for threads - it feels like forever...........
Off to ebay now

Are you in the process of supercharging yours?

Post Wed Apr 01, 2009 1:47 am

Oh - will master cylinder bolt on or do I need vw there too?

Standard master cylinder fits straight on too, as do some VW ones and some other BMW ones.

Mine is turbocharged, I can't find the thread of the guy who's supercharging an M30 now, can't remember which section it's in.
I only saw it the other day!

If you have trouble finding a Mk1 GTI servo then some Mk2 (1.3 I think) servos fit as well as some models of Renault Clio, but I think you need to modify (lengthen..?) the pushrod for them to work.

off topic... DRIFTBOY.. hows your motor running mate..? your m/s sorted now?

Post Wed Apr 01, 2009 2:48 am

Nah.

I dropped my Megasquirt round to Ant earlier and he's going to check that out for me.

If there isn't anything wrong with that I'm not sure where to look next!

Hi baurluvva, im doing the same conversion as well, but rather that going the route your taking the other optionwould be to change the engine mounts for either Ford Fiesta diesel or eccentric Bmw E28 engine mount rubber. There's a guy who has used the RHD Bmw items on his conversion. good luck |& waiting to see which option you take.

Hi cadtec,

I would go this other route but I have invested in poly mounts.......... possibly will upgrade the master cylinder to a 22mm one

I didnt think the M30 conversion needed a servo swap.

So you have hit the side of your brake servo?
Wont this affect its performance?

same as me i just dropped the engine on sunday and there wasnt a clearence issue with the manifold and servo.

off topic...... howdid you sort out your exhaust manifold?

Smaller servo helps with fitting the heater pipes on to the stubs on the matrix.

You can also shave part of the seam off on the inlet to get a few mm clearance.

There is no need to swap the servo if doing a m30 swap.
If your doing a M50 then you have to swap the servo to clear the manifold

Post Tue Apr 14, 2009 7:26 pm

mine fits in with no modification to either the servo or the manifold. there's only about 5mm clearance but it's never touched.
oh, engine in position 2.5 (redrilled e30.de mounts)

Post Tue Apr 14, 2009 7:33 pm

Mine is in pos III with poly mounts - so I think it sits a bit low and touches the manifold!

Post Tue Apr 14, 2009 9:40 pm

I'm on standard m20 rubber mounts with no probs at all
