Simon's 4-Motion Bora VR6

[trickysimon]

Hey simon, quick and probably silly question because no doubt you've said it somewhere earlier in the thread. Who are you going to use to tune the conversion / what software will you be running?

I have an R32 ecu with United Motorsport 630cc tune. Added launch control and flat throttle shifting

I'll be keen to hear how you go with it! I'm beginning to consider looking into different tuning options as although I've been pretty happy with my C2 tune i've got this annoying clutch in stall problem. Never used to bother me but having not driven the car for 6 months it annoys me now! Sometimes I find C2 a bit hard to contact so i'm considering either swapping to a different tuner or trying to find someone local.

How often does it stall?

[WhO]

It only stalls if you clutch in after having your foot moderately or more down. This could be after boosting for example or even just say pottering along at 60 in 4th or 5th, put your foot in for a couple seconds then back off, clutch in and it'll stall. If you drive around sedately or don't put your foot in it doesn't stall.

[trickysimon]

Do you think that is from lack of MAP sensor?

[WhO]

Not really as I've owned plenty of turbo cars that used a MAF and never had issues. I'd like to have a look at my AFR's when it happens as I'm wondering if it's over-fuelling. I thought it might be a vac leak but I had a decent look and couldn't find anything that looked like it would've be a big vac leak + if there was a nasty vac leak it'd have a pretty terrible which it doesn't.

End of the day I'm pretty sure its a bug in the tune. I might plug in vag-com and see if i can play with idle speeds etc to work around it. Not sure how to do that though as I've never done anything other than read codes with it!

Hey man, just picked up a candy white bora 4mo myself! Looking into dropping a turbo into it but having a hard time finding someone that wants to even give me advice on doing so. Any suggestions or contacts to talk to about making it happen?

[trickysimon]

Give Seb at Euro Automotive a ring on 0410 541 322. He can talk you through my build and point you in the right direction.
Expect to pay over 20k though if you want to do it properly.

Managed to get my new Oil cooler all mounted up over the weekend. Was difficult to find a position where it would receive sufficient airflow, but I'm pretty happy with how it turned out. A quick lick of paint and you wouldn't even know it was there!

Also a quick picture of the Intergrated Engineering surge tank and 044 fuel pump that I will be using.

is it finished yet?

Give it a bath before we see it lol

Actually had a busy weekend on the car. Ended up mounting the IE tank behind the rear drivers wheel. Had to cut a fair bit of metal out (which actually sent me to the emergency ward today, to get it out of my eye!) Running 4 new fuel lines sucked too! Fuel tank feed to surge tank, 044 pump feed to fuel rail, fuel rail return to surge tank, surge tank overflow to fuel tank.

Gearbox had to come back out as there was an issue with the bottom timing cog. Managed to get the gearbox out, time the engine, and put the gearbox in within a couple of hours. Bolted the exhaust manifold and turbo on properly and started putting other small parts on the engine. Seb and I didn't get to bed until 4am, so thanks to him for staying up to help!

Post clearancing an fuel lines.

Awesome thread - I have reading to do to catch up!

Hmmm, flat shifting will destroy the syncro...
