ok

[vanagonturbo]

Ok, FINALLY!! Problems have been solved... sorta.. turbo choice looked good on paper.. does not look good on car the turbo surges over 15psi. big time surging while under load and WOT.

My intention today was to pull the gt2056 off and put a stock t3 on. When I got the turbo off, I took a look at the turbine side and found that my clocking of the compressor housing caused the wastegate actuator to slightly open the flap. So, I put the turbo back on after adjusting the rod to ensure the flap was staying shut. world of difference and insert :banghead: here.

Now, I am on the hunt for the best turbo for my application. Ideas? I dont want to go with a compound setup just yet, just want to get it up and running and fast. The GTD would still blow the doors off of the Scirocco but the Scirocco motor acts like it has MUCH more potential. On the shelf I have a plethora of k03s, a k24 (TD style), 3 T3s (TD style), a T3 from a Peugot 505D, a gt2560r, and probably some other random stuff. Should I use something that I have or should I look at getting a new turbo. Goal is 160whp.

Thanks everyone for your help and input on this and I hope that my updating might help someone else in the future.

Also, I hear lots of talk about a gasser intake. I have LOTS of those. Would that help the surging? I would like to have 35-40psi of boost.

I'm using the Corrado G60 intake thats been modified for D ports and a Mercedes T3 turbo. It pulls 30 psi all day.

So that GT2056 sounds like the perfect compound turbo.

[vanagonturbo]

Agreed :p Need to get the motor broken in first before I think about compound. Worst case scenario, it goes on the Vanagon TDI. The T3 in the GTD is pulling 30psi no prob after a DP and exhaust. Tomorrows project is to finish the install on the rallye golf intercooler in the GTD so both cars will be operational. The GTD has been the commuter and I didnt want to put it under the knife until I knew what was going on with the Scirocco.

How does the spool time work out with the merc turbo? Rpm vs. boost? Is this on your Scirocco?

Ya got any pics of the GTD? I'd love to own one. What are you going to do with the old intercooler setup?

My turbo setup will go into the Scirocco when I finnish tuning the engine and nitrous.
The turbo spools up prety late. Like 3k rpm and by then it making 7-10psi. but when it hits, it hits hard and for long. Of corse, my pump can support the fuel to do so, as its a Giles super pump with a 10mm head and pluger plus a AAZ cam plate and rollers. Other that that, its the same engine as yours.

[vanagonturbo]

My GTD is an older version. Its not an SB engine. Mine is an '87. So no intercooler from the factory Had to make do with the rallye intercooler as I had it sitting around. I have a Giles pump, but I need to get it sent out to him so he can do some tweaks. Its a 9mm AAZ pump. For now I just have a tweaked 8mm pump that seems to do ok.

just out of curiousity, you asked me about buying the 2560, what were you going to use it on?

[vanagonturbo]

sorry, forgot the pic..

Was that your car at the Waterworks show? The cool dash shelf thingys? Sweet looking car.

I'd be interested in the turbo for the Mazda 323GTX.

[vanagonturbo]

Yes sir. That was the same car

Sorry that I dont want to sell the turbo. Should work great on that car though! i will keep an eye out if another comes up :thumbup:

Aw Snit. Oh well.

Your car stuck out like soar thumb to me. I loved it. even at a quick glance, I knew what it was and had to get a closer look. Really, nice car.

[vanagonturbo]

Thanks man. I really love it. I have about 16 cars and its my favorite! of course, its the only I bought in Germany so there might be some bias

Wow, sixteen huh. I though that my eight was bad enough.

Did you by chance see my Scirocco that was there. It was right around the corner from your car. The '78 Cobalt Metalic Blue, all stock, on Ronal Turbo wheels?

[vanagonturbo]

Its been quite a while since the show, but I do remember some nice Sciroccos! Sorry I cannot place your car, sounds familiar though..
