83 Ur Quattro 20v build

[Blagave]

I repaired some rust issues on the passenger side rear wheel area and the passenger rear trunk bubble and wheels well. I think this is the last of the major rust repairs, but wont know until the paint is stripped if there is anything else to fix

great point.....I will re-look at my situation....thank you

Varia.....its a 16" fan with 2024 cfm, I think I am fine for my application, used same fan on Porsche 928 LS3 Super charged making 650 at the wheels and a few other high hp motors, its not my first rodeo, but truly appreciate your incite and hope I am not wrong on this build

the rs2 fan (500 watts) is 8000 CFM.

928 build

I do agree that the radiator size is limiting

that fan is good for 300hp max (rs2 fan was 500watt, shorty 750watt).
If you want ac (i have it in my 500+ hp cq) you will need good radiator, fan and proper ducting

[Blagave]

I acquired a rare Ron Davis radiator and mounted a Spal Fan and a AC condenser. Yes, I want AC/Heat and all the nice comforts in my car. The AAN 20v engine is wider than the 10v so the radiator does not fit, So I modified the AC mount and the chassis to fit. The Audi AC compressor is a rear connection, which will hit the radiator, so I will mount a 507 side port used on mid 80's Porsche 911's.

Sorry for pictures out of sequence....not sure how to fix

[Blagave]

Varia, you are 100% correct. I will not be using the header, turbo or intercooler. Previous owner paid to have header made to fit his needs and the intercooler is too small, but nicely made. I am using another SS custom header with larger tubing and aluminum intake I bought along with FYY o1E 6 speed trans / matching diff and more stuff. Jeff will figure out the turbo I need

[varia]

Indeed great project good/solid base to start from.
Jeff is a very knowledgeable guy, he builds quality engines.
That intercooler wont be enough for 450hp yet 600, maybe for 300 if the core is quality

Good to see another sucker for flared box arches! Great project, looking forward to following this thread. Lots of photos, even of “boring” stuff, please.

Have removed the fuel lines, parking brake, rear diff, both front and rear sub frames along with KW shocks. Next I will get engine bay and underside cleaned and address any rust and then recoat underside.

[Blagave]

I cut the front cross support, so the motor and trans can come out the top instead of dropping the sub frame. I was given a front clip, so I cut out a left and right section and made a center flange. I welded everything in along with nuts on the back side and threaded inserts. Very easy removeal and install.

You should have seen mine. The passenger footwell was ready for Freddie Flintstone!

[Blagave]

Actually, there has been some rust issues that have been addressed. The drivers rear quarter has been replaced and both front rockers. The work was done very well. I just patched a rust spot in the engine compartment and have the rear passenger lower back wheel well to tackle. But for the most part, the car is in pretty good shape. Eventually the car will get blasted before paint and anything else will be addressed.
