34 housing is larger then 33 housing. (edit: REAR housing)

Id LOVE a 34 housing lol............

I ve seen the above comment made a couple of times and would like to know just exactly where they are different.

I'm mid way thru a DIY Split dump pipe setup on my S2 Neo (so would be an R34 turbo) and I have installed my mates rear housing from his R33 because he had already done the hard work of putting in the divider between the wastgate and turbine. I honestly couldnt 'see' any difference in size.

Was I wrong to do this?

He has also gone to a lot of effort to machine out the housing from the turbine blades out to the edge of the housing.

Not bad for a stocko phone camera.

P.S. Tangles I may have the 34 housing you're looking for....

the one on the right looks bigger to me

I think it is just that the R34 original housing is further away in the photo.

On the far left you can see the divided flange I bought and it matches perfectly with both housings around the inside edges.

I suppose the proof of what works best, will be in the pudding.

ATM I am running the standard dump pipe on the new (divided) housing so it sounds like passing wind when the wastegate opens...quite embarrassing really. :angry:

      I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
