Audi S3 GT3582R stroker Build (previously GT3071r)

[gazcuprablk]

totally agree with you m8 that underslung is a lot harder to do than top mount must be even worse for you with the gt30 and the transfer box etc compared to my gt28 and fwd ive had no end of trouble gettin at the dp bolts on mine but there is not much room there, what heat wrap are you using there m8? looks darker than the stuff i had did have mine wrapped but it kinda fell off lol

awesome build keep up the good work may see it next week if i pop up 2 combe

Small update... been suffering (yes, suffering!!) from man flu all week but managed to get over to the workshop last night to test fit the modded oil drain as this is holding up putting the car back together.

Fitted the oil drain and bingo!!! clears the drive shaft... I thought I would bolt the shaft to the drive flange just to do a final sanity check and yes, it still cleared.... the bolt heads didn't however and hit the braided hose... DOH!!!

Little bit of tweakage and bending in the vice and everything now clears. The oil drain is now bolted on... it was very tight on one of the bolts but its in and means I can now finish putting the car back together ready for starting her up over the weekend.

Does mean that I won't be going to Castle Combe this weekend though which is a shame but thats how it goes

[caney]

you have a nice pragmatic approach to things mate

 

[tufftybloke]

Thanks d00de... It am bestest way

Ok, the car is now more or less back together. Fitted the downpipe and tweaked clearances for the various pipes etc that are close. Its a little close to the drive shaft gaiter too but 'should' be ok. Will see how that goes then look at a solution if it cause problems. Bolted up the prop shaft, fitted the driveshaft and wheel.

Oil drain tightness...

Bolting oil drain to the turbo tightness... (bit of a theme here...)

All back together...

Tomorrow is finish exhaust section from downpipe to current exhaust system which needs a little welding, fill with oil and coolant and start her up... simples

I have my video camera ready too so all things being well my next post could well be a very interesting one

Straight of the downpipe by any chance??? Top work i have to say, whats the sensor in the bottom of the sump?

 

[Damoegan]

Sounds very nice. Love the way you can hear the turbo still spinning when you turn it off

 

[Willie]

Shes alive!!
Bet your well chuffed

 

[M1KEH]

sounding good, now for finishing the downpipe and mapping. Should be a fun ride with all that power and grip.

Yes, straight out of the DP, rest of the exhaust going together as I type...

Sensor is oil level..

[tufftybloke]

The car has been out for the first mapping run... all good apart from some dozy pillock neglected to refit the EGT probe wiring plug.... DOH!

Out for her second run now....

...more to come... hopefully

Been a funny old evening.... Bill was having a few probs with his laptop suddenly turning itself off mid logging (not mid flash thankfully) so it delayed things a little.

Mapping is nearly there, running a tad lean under boost at the moment.... 0.5bar boost at 3.2k rpm but haven't been pushing it until the fuelling is right.

Good news is though.... I have driven her home!!! WooHoo!!!

I haven't given it any welly due to the fuelling prob but she drives lovely under normal conditions. Fuel economy (assuming the DIS adjusts to the ECU fuelling requests) seems ok under normal driving conditions. Got her up to 40, hit the cruise control and she sat there happy as larry...

Dropping the car back to Bill tomorrow night when he will sort out the mapping for hopefully the final time then jobs a good un.

Phew!!!

Just been reading your thread, like what you've done, oem look is gud, and hope you get it sorted nice machine

 

[mat20vt]

well? all sorted?

 

[tufftybloke]

Not yet... got a fuelling issue on boost and its running a little lean. Bill has a new map ready but I am going to check the fuel pressure to see if its the inline pump causing a prob or at least isolate the pump as a prob and move on...

Apparently she was holding 1.5bar to around 5k then nudged up to 2bar to the redline... next file has been tweaked to 1.7bar to be safe.

I have been driving her around though and taking it easy... she drives lovely but there is more to come. I have prodded the loud pedal a couple of times and feck me does she go and thats with no timing advance dialled in and with the fuelling issue.

Seriously considering water/meth injection but thinking I will save for valves as she does seem to want to rev.

Its a ball ache having to drive off boost knowing what she is capable of but rather that than a melted engine.

Hopefully it should all be sorted at the weekend and I will be able to give a full report of how she feels and drives...
