20G turbo upgrade from Buschur Racing.
I would really like to see this turbo put Evo's in the high 11 range on pump gas. To me then it would be worth the buy. I'm really liking what I see so far and I am not really paying attention to the dyno numbers since they vary to much to compare.
I do have a few questoins though,
How much boost would one be able to run on 93? I'm assuming 22-23 psi considering what the stock turbo is capable of pushing on 93.
Also, what would be the max boost this turbo will support? Is 25psi the max? I would really like to see it support 28-30psi, but that might be asking alot.

With all the basic bolt-ons, I haven't seen a stock turbo EVO make over 300 whp on pump on the local Mustang. I've never seen one break 300 whp on race either, but they probably could with big boost and a bunch of timing on C16.
Remember, we're talking about a car running an 11.3 here. Yes, a few cars with stock turbos have done better, but it takes a bunch of work.
Also, cudos to Dave for not manipulating the numbers. You'll get used to them and the track doesn't lie.

I know there is much more to it than a peak number, but for all the talk about this thing...that peak number better be higher than stock all else being equal. 330whp on a properly calibrated MD is not hard to hit on the stock turbo with basic bolt ons.
So it's 800 if you provide your stock turbo as a core? How much for just the turbo alone? Can I send my turbo AFTER I get the 20g or is it needed before hand? Does it use the stock manifold? What else is required (besides new nuts/bolts/gaskets) for the install?
I think this is the turbo for me! just need to figure out some details

PLEASE READ THIS IMPORTANT 20G INFORMATION!!!!!!!!!!
First want to say I LOVE this turbo. Very happy with the performance and steady boost it is providing on my car.
Next, this weekend I had a EVO owner come in that we are doing a large build up on his car. I told him when he came in for the shootout I would let him drive my RS and after he did then he would know for sure that the 20G was the turbo for us to use on his car.
We pull out of the parking lot and it looks like he is already impressed. We start out of town and I don't know what he is doing at this point as the car is jerking and bucking and compressor surging, I say, "Damn, what are you doing?! This car has never done this before." He says, " I don't drive just at WOT, I have to modulate the throttle in boost in a corner." I am thinking, "WTF is going on, this is horrible." He drives it for 10 miles or so and says how impressed he is with how fast the car is, but the compressor surge isn't goign to cut it.
You know guys, I have let probably 6 guys drive this car since the 20G has been on it and nobody has had it surge. It is something to do with the technique of this high boost-part throttle driving style of a road racer. This turbo is NOT going to work if that is how you drive. Very odd.
I want to get this out there. We haven't shipped a turbo yet, if any of you think this may apply to your driving style DO NOT let us ship your order. Call and we will gladly return your cores or replace them with new ones, whatever it takes. I don't want anyone unhappy with this turbo.
I am both pissed off and glad at the same time that I discovered this before I could get the word out. It is very very odd to me.
As a side note we dyno'd a WR this weekend. As the car was coming up on boost on the dyno I could hear it surging too. That is puzzling as I have only read good things about it being road raced, any of you getting that surging at high boost part throttle with that turbo?
