Audi 4000 Go or No-Go?

So here's a new twist. A friend just offered up his 240 turbo. Needs a fuel pump (he thinks).
He's getting married and he's thinking he doesn't need two cars. And it's cheap, and the heater works, and it has a radio, and comfy seats... all things that my wagon is lacking.

I should add a pole to this thread.

Need you even ask???

The bigger question is when you gwanna cage the Volvo?

137km/h maybe Top gear is 500rpm:10mph and the engine just makes noise over 5000 and not power... Maybe if you found a deep enough mineshaft and disabled the rev limiter it'd go that fast (or swapped in different gears and/or an engine that revs!)

I got the engine from someone who pulled it in anticipation of a swap into something. He cut the under-dash wiring to the engine harness, which I guess is bad if you're putting it in a 4000, but I'm not putting it into a 4000, so it probably wouldn't have mattered. The computer to engine stuff is intact. The biggest things keeping me from doing the swap -right now- (shooting the engineer and putting it in as-is) are figuring out how the hell I'm going to run an intercooler and getting off my butt and tracing all the wiring out. Which I'm not going to bother doing until my Mazda stops doing its impression of a coolant fountain. I also have an 034 fuel rail for someday soon, because one car on Megasquirt ain't enough.

Oh yeah - better than the turbo setup is to find a 7A engine which is the non turbo 20v used in 1990/1991 Coupes and 90s. Plenty power stock and it's the same head, block, crank, and rods as the 20v turbo engines. But better cams. Then you're just rods, pistons, big turbo, and programmable injection away from as much power as you feel like making.

Lol. Had a blau cam and some other nice little bits, nice long run with a downhill finish. Cleared 135, I estimate the 137. I was dating a girl that lived 10 miles past nowhere and had lots of open road.

I'm more concerned about the wiring harness of the car you are putting the engine into. The people I've talked to have just coiled it up and tucked it away, or cut and sealed it at the firewall. I dont want all those extra wires hangin about.

My MC2 is going into an 80 quattro. I've started tracing some of the wires back to the ecu, cutting them individually and pulling them. But it's a shitty process. Tomorrow I'm gonna run the Red harness through the firewall, make all the connections i'm gonna need to get it to run properly and then cut everything else out. It probably would have been easier to have just started that way, but I never claimed to be a genius.

I have owned 2 4kq s, and they were great cars, I took my car everywhere, mountains, the beach (deflated tires to 20psi or so and it crawls over the softest sand!) They understeer bad and the suspension needs work to make it decent,

The 7A 20v engine was very common vs the 3B (20v turbo) and will fit in the car, its EFI too. The MC1 /MC2 10v engines out of the 5000 turbo are getting harder to find as the cars get older.

I do think the 240 is a whole lot easier to work on and quite a bit stronger . I mangled a few control arms on the 4000 pretty easily.

Both are good fun if in decent shape!
