Here is a picture of the Turbo being fitted to my car next weekend.

What the car comes with stock, compared to new one:

350bhp + is very achievable.

It's a nice upgrade :cool:
I would bolt up the turbo setup to the engine and just cranke the whole lot in, it's a nightmare to work on with the 4wd otherwise.
I take it your doing the welding for the downpipe yourself? Keep up updated with pictures :cool:

Cheers. Car currently has a k04 and somewhere between 290 & 300bhp.
That is a spare engine for the track car I share with a mate, but for my car the head will be coming off to fit this. Downpipe will be mocked up by me and my mate, then another mate with an engineering company will weld it all up nicely.

reesicles my dear little chap.
You already know this, but I like what you're doing muchly.
I shall be down your way in the not too distant future to do some experimenting of my own with Mr. Parsons and his whacky ideas!

That turbo looks bigger than a human head. Now that is when you know people are serious! :shocked:
Good luck with it...Will keep an eye out! :smiley:

I wouldn't recommend it mate. He has you spending money you didn't know you wanted to spend.

Some inspirational welds to spur you on buddy :evil:

Can't wait for a little outing in this :cool:

Very nice. Everyone loves a good weld

I'm sure that can be arranged :cool:

I couldn't agree more, extreme penetration is where it's at :evil:

I think every man is a weld perve at heart lol

Update for the weekend
Work started about 7pm Friday. Within 40 mins the head was off and out the way. Got the turbo and mani bolted on to the large port and had a mock fit. Ben's opinion was their wasn't really enough space and part of the bulkhead would need a bit of tweaking and the air con pipes would have to go. Bugger. As I hadn't had it gassed since the k04 work in August and I wanted the turbo on the car, it had to be done. Put the new gasket on and the head was fitted properly. All bar 2 turbo lines were fitted as well. Inlet mani was fitted back on to the car and the cambelt was back on the car and work stopped about 11.30ish.
Work started Sat about 1pm.
Jobs done yesterday were:
1 of the 2 remaining turbo lines were fitted. The fitting for the other one isn't the correct fit for the hose.
Ben decided to become an exhaust fabricator and got the downpipe well underway, mocked up and tack welded in place, ready for a mate to add some fancy looking welds to it.
Tip was bought and pretty much done. DV is welded straight onto an alloy 90, n75 boss to be added by the same fella that is doing the exhaust, then it's done.
The down pipe has been sorted so it can be taken out with the turbo in place and the head on which is a bit of a brucie bonus for any future works that might take place.
Beyond the down pipe, I have just bought some additional 3" stainless to make the exhaust 3" all the way to the back box. Partly because the car is very quiet and partly because one section of a straight in the exhaust has a massive dent in it..
I say all this very casually, but hardly any of it was done by me.
The work was done by Ben @ Parsons Performance.

Back from my holidays so time for an update:
(http://i1158.photobucket.com/albums/p607/Reesylad/Car/Garrett/5E190D5C-3538-4409-AB39-F1AD35EC37AA-5616-000004752CA07EF2.jpg)
Downpipe was a bit more of a mission then first thought, fella welding it has said it was a bit of an effort to keep the 5 bolts on the flange accessible, but as it can be done, it will be.
Downpipe was sorted and heat wrapped.
TIP was sorted.
All was looking good.

Posted by Ben from Parsons Performance
Had a few hours spare this evening so replaced the dented scorpion 2.75" pipework with 3" stainless. It's 3" untill just before the backbox where it reduces to 2.75", this is a tempory measure until Reesy gets another backbox.
Tig welded by my own fair hands, first attempt at a cat back system, pretty pleased with the outcome.

240g/s @ 13psi!!!!!! This things got serious potential.

Drove the car Friday night for the first time with the new setup.
It was running about 10psi with a slight creep towards 12/13 in the higher revs. It's quite strange in the way it drives though. It doesn't feel particularly fast until you look at the speedo. It was raining and their was also a lot of standing water but it was quite underwhelming really. With a tweak of the actuator it could easily be used like this every day though.
It also sounds really good, sounds more appropriate for the power it has without being too boomy. Need to do a few miles on it before I know exactly how it'll sound, but overall I'm happy with the exhaust.
Going to check everything over today before it is released back into my (lack of) care and going to put on a more boosty map I have got to see if I can get some epic g/s, as we all love epic g/s.
It also starts to pull comfortably in the higher gears from about 2.5k, so lag isn't really an issue either.

Post from Sat evening:
It's not 100% healthy unfortunately, but I'll get round to that in a minute.
2 exhaust clamps have been fitted.
Jubilee clips fitted to the TIP and that's sorted.
The oil leak that was causing a bit of an issue was located. It was the oil feed restrictor, despite being up very tight it was leaking a fair amount. Re tightened it, went to the petrol station and it was still leaking. A washer or two was added and it seems to have solved the issue.
As the car was not making quite the 1 bar at actuator pressure, the actuator was wound out a tiny bit. Seemed to have made a bit of a difference and the car goes pretty well. Got back to mine and loaded the boosty map on, idle was instantly better. Opened it up on the bypass and the needle on the boost gauge shot up to and past the stop on the boost gauge (30psi) so i quickly shut off..
As it had done once on the k04, the hose linked to brakes popped off so as we pulled into the petrol station to wind the actuator down and sort the boost leak, the car had very little in the way of brakes. Not ideal. Ben has said that a one way valve can be put in place so it should stop it from happening again in the future..
Actuator slackened right off, we set off again. Car was still making late 20's psi so I'll be speaking to Dan about lowering the load. I have rods and the turbo could probably take 30psi as it pulled that all the way to the redline, but it isn't really necessary. I'll post the vcds logs that were done earlier, but it involved maxing out the MAF
Decided to take a couple of drive by videos. Car sounds epic, especially when it comes on boost, also makes large pops on overrun which is pretty cool. Left without getting a video though as the exhaust is making a horrible noise. Hoping that it's just the gasket for the blanking plate that is on the manifold, failing that it is possibly the clamp that joins the decat to the downpipe..
When trying to see if the car still drove O.K despite the noise, the same hose popped off again which is *** annoying. Popped back on yet again, N75 unplugged and I drove the car home. Drives fine, just sounds horrible. Over a 12 miles journey with the odd burst of boost but generally keeping with traffic, it averaged (supposedly) 37mpg, and before anyone says it: the dis is calibrated as it was running very early 20's when boosting and not boosting.
It has since been diagnosed at the wastegate blanking plate gasket, so I have two on order

Rods fitted?
What size maf is that?

It does have uprated rods.
It's a stock s3 80mm maf.
