      Just bought a 1991 80 Quattro 5 cyl NA, been reading a bit on some things, the plan is to swap in a B5 1.8T, lower it some, possibly a 5 lug conversion. I'm not really seeing anything suspension wise online except $400 lowering springs, what years of Audi interchange between sedan, coupe, Avant suspension wise? This my gateway Audi 😂 had alot of VWs over the years.

      The swap can pretty easily be done. I know of a couple B3's with both 1.8t's installed. You will have to make mount arms for it though. If you don't want to make them yourself, I can put you in touch with someone who makes very nice stuff for these cars.

      5 lug is pretty easy. You just need 4 B5 rear flanges. The brakes, you will have to sort out yourself.

      As for the suspension, that's a little harder. Of course you have your normal springs. H&R, B&G, and weitec. There is also the K&W coilover kit. For that, I think you are looking around $1800, I could be off on the price... There is also the DIY coilover setup. A lot cheaper, but more labor intensive. If you go to motorgeek.com or theprojectpad.com you can look up this setup.

      As for Interchangeable parts... The 89-92 80/90 are the same car. Be carful though, the late 90 came with the 20v, and bigger front brakes and knuckles. As for the CQ, they are generally the same, but because the rear weighs more, the suspension is stiffer.

      I'm currently running a complete weitec suspension kit for a CQ on my 91 80q, and love it. It's a 45mm drop on the coupe, but on the sedan the rear only dropped about 35mm. Really helped me from scrubbing my tires like I did with the B&G springs I had on previously. Although, it did look a little better with the B&G springs...

      Wasn't planning on coilovers, kinda like how spring/strut combos ride better than coilovers, much more comfortable. As for mounts it seems pretty straight forward to make or those can be bought out of a B4 1.8 NA cabriolet from EU right?

      I'm assuming axle splines are the same on the B5 and the B3. Good to know about the 20v differences though.

      Found a donor car a few weeks ago, posted up a part out ad on a few different outlets, guy that owned the car for years messaged me I inquired about the maintenance and he said the engine was meticulously maintained by his uncle who's a Audi master tech so that's good 😁

      I found some MK3 lowering springs awhile ago and ended up getting them cheap, been reading about some Frankenstein suspension builds and or strut spring combo setups, I know MK3/2 suspension bits are basically identical. But do they basically drop in a B3?

      Been pulling this A4 apart slowly, the AEB is out and on an stand to be cleaned and resealed. Plan to get a cartridge for the KO4 and keep using it, probably need injectors and other things with a tune at some point I imagine.
