yeah thought it was from ATP

bought the same turbo for a customer awhile back with the same anti surge compressor housing but with the .63 exhaust housing and the anti surge realli does make a difference if ur going to be using the .63 housing

what sort of difference are we talking? I have the .63 and no surge issues. boost control, shit yes, surge, no. I do have 256/264 cams though.

-33- also has a .63 IW. He hasn't mentioned surge either, just the boost control problems

good choice of tuner too btw Gary

Yes it's a funny thing Dave, some cars have surge, some don't. Cams will definately be on the cards for the future. I'm hoping that will reduce the overlap for more timing.

Yeah, I think Yavus is great, takes a cautious attitude to tuning. Don't you just get sick and tired of tuners that shake your hand then tell you to come back in the afternoon to pick it up ? I want to be there to tell them how far to go and make sure tune for drivability, fuel economy, safety and only then power.

I've been there every time my car has been on the dyno.

I don't know that cautious is the right word, but he is certainly very careful during the initial stages of a tune making sure all the basics are covered before starting to chase power.

I can guarantee he will push you to jam some boost into it. :P

Or maybe he just does that to me because he knows i'll let him.....

And I can guarantee I'll let him jam some boost into it. BUT, 270 is what I'm after so we'll see. Buy the way, I'm thinking peak boost on this turbo would be around 22lbs. The compressor map seems to indicate 17lbs as right in the meat of the turbo's potential. What do you think ?

It'll depend on the engine really. I couldn't run more than 21psi with my old setup before valve float, others have run more.

Because of the boost control problems i haven't really been able to push mine but it was making 255-260 pretty easily on 16psi. You may need a bit more boost as you don't have cams in there.

      There was a great one on Victoria Rd in Gladesville too back in the day. I can only assume GTSBoy is thinking of the mill up on the wollondilly, no restaurant there any more but they have restored the original steam engine on site and run it every few months, have an annual steampunk festival etc @The Bogan, you came to the wrong town for restaurants. we have a few reasonable asian and indian options but the Paragon is as good as it gets otherwise. That brewery is apparently just opened, been meaning to give it a go some time. The Highlands have plenty of fancy options but I suspect you are more a hearty eater than fancy eater

      Going by the intake & injectors I'd be guessing it's a DE, check the head casting number, should be 5L8 on a DET, 5L7 I think is the DE number.

      For future reference, if you need to use Deutsch connectors but don't have the proper crimper for the round style pins, you can get regular style crimp pins too

      No. The castings are all the same. As you have the inlet off, simply measure the diameter of the inlet ports and compare with the freely available on the net sizes of turbo and NA. The NA ones are small.
