1990 90q 2.6 20v

[dspl1236]

Hello All,


This is my 1990 Audi 90 Quattro 2.6 stroker build. I purchased this 90q 2.3 20v with a buddy to fix and flip.... ended up just buying him out to build the car for myself.

I wanted todo a short deck 20v stroker, very little info is out there but is doable. Had to-do some block craving to clear the rods and do some piston massaging due to old vs newer valve offsets.

Over the last few years I have been collecting parts and putting together the motor.

The other weekend I pulled the whole rear end to refurb. New wheel bearings, axles, etc. Found what I believe is the last set of reman G60 calipers in the county. All new pads and rotors on the way. Ditching the oem mesh 14's wheels and swooped up a set of cheap knock off mesh 15x8's 4x108 and 4x100 to share with my mk2 Jetta.

I have been eyeballing the Verkline subframes...

Just kidding. Got an alignment for snow fun.

Great info on what's needed to build this. Makes me want to sell my spare AAN and just build the 7A I have in my CQ. Thanks for sharing!

I do plan on building a 2nd 7a into a 2.6. The 2nd time around I plan on different pistons I would prefer not to carve them up as much as I did.

A 92.8mm crank would be dang near drop in with these tsi rods and pistons. That gets you 2480cc.
