Maybe some good news.
Car is now in bits,and the misfire may simply be the MAF.
Ben said the MAF was filthy,so hopefully it will turn out to be the cause of all the banging and stalling issues.
That would be a really cheap fix.
Wish mine had been a "cheap" fix lol.
I went to put the ARP head bolts in the block and found out he had modified the block to take a thicker and longer ARP bolt so he could use the Golf head doh. Block back off to machine shop for inserts!
Oh god I feel for what you're going through.
I've had one non standard engine previously and it's neither easy nor cheap and just means constantly needing the right parts.
I was fortunate that the engine builder was also the guy who looked after my cars and your predicament is way more difficult.
Mine is in bits right now and the turbo etc should be going on now.
I'm nearly on top of it now. I know the following LOL
Head Golf MK3 16 valve
Block AXX or BWA golf MK5 TFSi
Fan belt Citroen
Timing belt 144 teeth
Block modified for longer/thicker ARP bolt kit
Clutch and flywheel (still being established by Helix but defo non standard in size) smaller
Rear end all golf VR6
Front end all S3
Custom sized rods
Custom pistons
Power steering pump Audi
Power Steering rack Golf mk4
Rad and intercooler SpecR
Rocker cover SpecR
Condensate unit SpecR
I have a passport for the car now with all the part numbers to make it easier for me in the future. Been a ***** though figuring all that out!
LOL
Most of my pistons had picked up at the top and a little on the skirts which I have polished out with my dremmel.
These pistons are quite tapered as they are 82.4 ish on the skirts and 81.7 above the top ring. About .5mm gap above the top ring so Im not bothered about tidying that up as it don't touch the block anyways. On the skirts ive been more carefull though because if you take off too much there you will get a bit of slap and tickle when cold lol. Very fine wet and dry used there and then red scotch to get the wet and dry grit out of the ally and then a good wash and dry.

good news
Me likey!
Want u doing with your 3071r ?
More sexy time pics lol
Every time I read this thread it gives me the urge to go big turbo - I'm not even 2+ yet either
oh my...
So is it now running properly or are they ones to check still?
Wmi has been known to destroy a few peoples throttle bodies, so thats a good shout.
Im sure itl be something simple. best of luck
Smoke test the whole system?
Also how big is the intake to the turbo? On large intakes with large turbos with big inducers, whilst at idel they can swirl the airflow in the TIP causing unstable maf readings at idle, check those readings at idle, shouldnt fluctuate much at all.
Hemce the whole 'bigger maf and you lose driveability and smoothness at low loads'. It can be combatted with flow straighteners in the tip tho, with 2 plates welded in perpendicular to each other for example.
I plan to do this on mine with my rs4 maf and 90mm intake, although not HUGE, it might be one of those small things that makes a big difference to driveability wen you want to potter around.
Coils checked ok, have you humoured yourselves & tested another set anyway?
