944 VS 2002 Booster

So I currently have a good working 944 booster installed in my E30. I am looking at swapping an S54 into my recently injured E30. What is the size difference between the 2002 and the 944 booster. Is it possible to run what I have. I am hesitant to go booster less as I have E36 m3 front brakes and 318ti rears and I don't know how well that they will work without a booster.

First:
Fix your brake bias problems by dumping the 318ti rear brakes as the cylinder sizes are wrong for the M3 fronts. Easiest but costly fix is:
Massive Wilwood 318ti upgrade


As far as booster, I am not running one any longer, but going manual with this from Massive:

Yeah my long term goal is to get the complete matching front and rear setup from Massive. For now just want something to clear my future S54. If my current 944 will clear with a shim and my current solid mounts I would gladly do that but if I need to go 2002 I just need to know which 2002 unit to get.

I'm not sure any of those will fit with the plenum.

May need to do something like that to allow for clearance

I know the 2002 will fit I am just wondering how much bigger the 944 is than the 2002?

Yea I'm running kassels box. Even with a 944 booster it's still a right fit. It would need to be at least 2-3 inches smaller to fit the box without modifying it. Maybe more

I'm looking at the same delimea right now. From what I heard you can shift the booster over slightly.

How is the Kassel box, I read mixed reviews and I am wondering how much it affects airflow with that much customization.

Does anyone have a 2002 booster on a S54 E30 to measure?

Its not bad quality. It looks like crap with a corner cut off and epoxied back together but there is no way around that. Typically yes you could drill new holes and shift it over but I still don't think it would give you enough room for a stock airbox. Unfortunatly mine is RHD and the braking set up behind the dash did not give me this option.
