Building a S2 mk2 golf

[Joseph]

This is such an amaizng build this is easly the best mk2 ever made , did u use the orignal S2 subframe and the cut all the top mounts and the surrounding area's out , also is that the S2 rear diff and the main centre prop shaft?

I just found a nice review of your project:

Even references to this forum

is it possibol that you would have a holliday i denmark around the 11-12-13 sept.

our danish club golf i this year 25years old,and we have rented padborg park(racetrack)
i would have invited the s2forum but our rules say only vw´s on the track(can see on the flyers that audi cars may also drive on the track will check and make a new tread).
and yours is a golf

Surge?? You must be using a Garret, lol

Thanks for reply, a bar at 3700 isnt too bad i suppose, whats your max boost?

[audiman]

Im forever hitting the rev limiter in the golf. I forget to change up as it pulls so hard all the way to redline, which is way into red on mk2 clocks and i just forget.

Ah yeah, my last dump valve (a turbosmart one) had the function to adjust if it was open or not and it got around this problem.

Thanks for the link for the dv, take it that might be a bit big for a aan setup chipped and with nitrous? not too worried if I get slightly more lag or if I loose a couple of bhp because at a later date the engine is getting changed out and turbo upgraded etc.

Not too sure what you mean about lag and losing bhp, only thing is if your on motronic and the DV opens on idle the car will stall and run rich as a pig on gearchanges.

I run aftermarket with a map sensor so its not a problem.

Sorry i stand corrected, the seller says it works fine with MAF cars

This is the same DV as mine at a fraction of the price of a tail and mine works spot on

The nitrous is controlled through the ecu via an output but make sure if your using rpm to switch that you turn it off at redline. I made this mistake and blew my inlet mani to bits.

The problem with a microswitch on the throttle is your relying on lifting your foot when rev limit is hit.

I would not worry too much because the only time i found myself hitting the rev limit repeatedly was doing burnouts at the dragstrip.

I would guess the power between 500 and 550 hp.

1 bar will be hit at 3700rpm in higher gears but this turbo will surge if i dont drop it down a few gears. The most usefull rpm seems between 5000 and 7000rpm and is allways at full boost up there.

The thing that made the most difference to how the car drives was fitting an MS-IBC boost controller. It made the car feel a lot crisper on the throttle and is easy to set up, the closed loop really works and keeps the boost stable as a rock. It's much easier than getting the laptop out every time you want to change something.

Awesome thread, loving the pics.

Any idea what sort of power your running? what revs do you make a bar of boost?

Dont seem too laggy from the videos.

[Acidburn]

A copy of a tail blow off valve by xs-power, because they are cheap.

Hopefully the car will be on the road ready for some action very soon.

do you have a link to somewhere I can get one of these.

Also how have you been controlling the nitrous? manual switch?

[quattro84]

Nice low-cost solution! This setup with baffles works for a lot of japanese cars.

[gnutz2]

I know what you mean but they hit the windage tray first.

[Rusty]

I'd put an end stop on the baffles to stop the possibilty of them swinging up and hitting the crank, highly unlikely situation but you just never know...
