Just tried and no luck. 20mph flat out and same boost is reached at same speed and feels no different.

Thanks to Colesy for undamaged front subframe. I will get it refurbished with bushing and swap it over.
Also, on the drive home I hit a milestone

I've done a boost test and no leaks. Does anyone have a spare working N75 they could lend me to test mine? Don't have a boost gauge so feel a bit scared to disconnect WG pipe.'93 Audi 100 Avant - R.I.P

Just got some black/blue smoke out of the back Started her up, and when trying to rev she was hesitant to pick up revs and when I properly revved it i got blue/black smoke and then fine again. I turned her off, did it again and same thing? 
Any ideas chaps?

Same you said to me. Black smoke - leaking injector.
I've only seen blue smoke, when car burns a large quantity of oil.Comment

I'm thinking the same, so I'll do what Dave did. Get pressure up, and put it in jars and leave it for hours and see what's happening. I have spare injectors at least.
It was like mix of blue and black, but there is no way oil is ending up in cylinders.'93 Audi 100 Avant - R.I.P

I had already bought the standard bulbs, Janis, so my dash has the original orangey illumination, but I really like that deep red appearance - very ethereal!

Quick test fit and I like it, fits like a glove. Need to get a red LED so it's a bit brighter

Sorry to tell you but you are a long way from fitting a boost gauge in that location. It's only been done with two other non-C4 UrS gauges.Originally posted by hunker7 View PostQuick test fit and I like it, fits like a glove. Need to get a red LED so it's a bit brighterRS2'd 93 UrS4 5 spd sedan
