Audi Coupe Quattro 2.3 20V - Czech Republic

The engine wiring saga continues..On Tuesday I wired all injectors and then went to the ignition coils wiring. I have to say, crimping and all the stuff around is really time-consuming. I found making an engine harness cool and relaxing (sometimes), on the other side it pisses me off when you do it in the engine bay and you don't have comfort or you can't reach some points
It is a challenge for sure

Custom engine wiring is done. I am so happy it's finished, everything is working, and no errors at all. Amazing feeling. Now have to make a new turbo manifold, aluminium coolant pipes, downpipe and the rest of exhaust and car could go to the dyno.
The wiring was a tough challenge but everyone could do that

Volvo EPS works on Can-Bus through the MaxxEcu and Rad Fan works on PWM module trough Maxx as well, so far lovely ECU. Cant wait till it runs

I've been very busy last week. I tacked the turbo manifold and it will came up really nice and also the downpipe is tacked. Now have to weld everything it will be a lot of welding for sure, but I am really please with how this ended up. Hopefully, I don't **** this up

Yesterday i started welding the turbo manifold. Its really hard to reach lot of spots, but I tried to weld as much as possible when everything is tacked to prevent any shrinking. The argon bottle is empty, have to wait a week for a full one but then I will finish the rest then I will break each runner and weld what is missing and then I weld it into the collector and head flange. Its a really challenging job for sure.

[Tom_]

3 runners are fully welded. Now have to finish the rest two of them and then I could weld it all together. There are a lot of spots where I can't reach with my tig torch so it has to be welded outside. A little bit scared of shrinking, but seems fine so far, will see how this ends up. Hopefully, next week will be ready. Also, my WG outlet is missing, so it will be drilled and welded during the weekend I think. Otherwise, welds look pretty nice if I consider that I weld only sometimes and not my full-time job.

Wow, looks great! EGT provisions too, nice. Im still planning my maxx install. Gonna have a thorough read through your thread. Tks!

[Tom_]

Thanks,you are welcome. I cant wait once I hear the engine. You will be really pleased with Maxxecu, really nice piece of ECU

[Tom_]

Manifold is almost done...two welds are missing...one on cyl #1 and wg outlet hole is missing...but next week manifold will be completely done and could be finally mounted with a turbo onto the engine

[Tom_]

Manifold is DONE !! fully welded, prepared to be mounted on the car. The merge collector came out really nicely as well as the whole manifold..Now have to finish the Downpipe, make a new oil hose for the turbo and the car could be started. I was thinking I would make a screamer pipe, but there is small space now, so I will skip the screamer pipe and make it into the DP, I think the police and MOT will be satisfied with no screamer pipe
IC piping I will make after the car will be started. Not sure which way I will route the IC piping but I want it as short as possible.

Just caught up on your build......Wow......a lot of hours and nice work going on. Your almost there

[Tom_]

Thanks mate, I appreciate that. Yeah, a lot of hours sofar , but getting there

[Tom_]

After reclocked the whole turbo, the initial DP doesnt fit so I have to made a new one. Now its tacked and seems everything will be ok. Its a tight almost everywhere but fits nicely . I have to add a flex joint to wg/Dp routing (ordered one) . The hood could be closed now so I am happy as well not sure if the headlight will fit...but I Would say yes. Now have to weld everything and also to find some turbofilter which will fit there or made some pie cuts piping and route it somewhere where will be access

[Tom_]

Donwpipe is fully welded. Now waiting for stainless zip ties , afterwards I could wrap the downpipe + manifold with heatwrap to keep the temp inside those pipes and not in the engine bay.
I will try to run a screamer pipe and see how loud or annoying it is if not, I will keep it like that Fit the downpipe from up is no go, and from bottom is really PITA even without WG inlet.

[Tom_]

The Wastegate outlet is tacked, but I noticed that the wastegate pipe is close to the drain hose and to the starter wiring so I would put some 40mm straight piece of tube to the wg flange, and then will be ok and there will be more space around. Also, the DP gets the titanium heat wrap. Looks cool.
I ordered some heatshield sleeves for wiring, hose and fuel lines, to keep them as cool as possible.
