Buschur Racing 50 trim turbo kit......
A boost leak check, what does that have to do with boost creep? Nothing. Boost creep means the boost go UP uncontrolably, not drops off.
The turbo, I don't want to go into details on any further than I have. I am not going to turn this into a turbo manufacturer slamming thread. It will leave hard feelings between our company and theirs. I have enough enemies already. Bottom line is it doesn't work.

true but you can do it for less then 3000$ you weld a 38mm tial flange onto the manifold. run a 38mm gate, and you need a dumptube with another tial flange and ss piping. the gate and both flanges shouldnt be more then 265$ the labor if done consistently the same everytime, should bring the total up to 350$ subtract the price of the internal gate, prob 75$-100$ at the most. should make the total price 3250$-3300$.

Dave, was it just the boost creep that made this turbo worthless? I'm trying to discover what properties of this particular turbo made it so terrible with its supposedly high flow ratings. I was going to take a stab at guessing the turbine wasn't flowing properly or some such to give such odd outputs.
Any information would be appreciated
Thanks in advance

That's not how Dave rolls. If it's not tested and proven to work, Dave's not putting the Buschur name on it, you can bet your *** on that.
however, a full 50trim kit for 3G's is already the cheapest price out there for a high-quality kit....asking him to sell it for 2g's cause it'd guarantee sales is like going to the mitsu dealer and tell him to sell a new MR for 20 grand cause more people would buy it.....
no way in hell that'd happen.
We could have told you that turbo is absolutely horrible with the internal gate. HOWEVER it is ****ing AMAZING when you use an external gate.
This is on a wee little 1.8L 9:1 Honda motor.
22 psi.

25 psi.

30 psi.

Hell of a turbo if you ask me...

The new turbo.......let's see how can I try and make this make sense, probably can't..........haha
This turbo was not a real 50 trim. As I said somewhere in the last 22 pages, this turbo was an ET50Trim. The ET stood for extended tip. So while the trim size ended up being a 50 trim it was marketed to me to outflow any other 50 trim available. I can't remember exactly but I think they said 56 lb/mn. That's why I tried it in the first place.
So now I wanted to find another turbo that would flow about the same as this one and that is what I have ordered. So the new turbo I am going to use, I am hoping, is going to make the power this one was suppose to.
I am NOT going to run this ET50 trim with an external gate, it will do NOTHING to help this turbo situation.
If you are truly interested in an externally gated 50 trim we have them, Tial 44 mm gates etc. I have 5 BB 50 trims coming in anyday.
As for the 200 tq, it was actually around 280 ft lbs, still way off from 412 with the 20g-9-5.

The wastegate is your problem though. We did testing w/ these setups a year ago now and had no luck trying to make the internal gate funtion properly either they were creeping or not holding. We use this exat turbo on numerous of our setups and have had great success w/ it.
he's referring to the BB proven 50 trim, not the non-BB that Dave tested.

Onto the internal gate....I really personally (Read OPINION) believe that dave dripped the ball on the internal gate. He really needs an External and I guess an 18 Pound spring and so one. I justy don't see how an internal gate could possibly work efficiently.
SO many slow guys that are experts! It's quite amazing how I am being told how to make a turbo kit work from guys that haven't built, designed or tested anything. Glad I am getting 4 days of for Christmas.
The boost creep was only part of the issue, the boost creep made the turbo kit not-usable for a street EVO with pump gas only.
Once I turned the alky on the boost came up immediately to 27 psi and held a nice flat line from 4200 rpm to 7000 rpm.
For the NT Integra guy with this turbo. Funny you'd bring it up, the designer of the turbo told me how great it works on Integras and Scions. Then went on to say he messed up sending it to me to put on an EVO as it wasn't designed correctly and re-thinking the turbo he should have never sent it.
As for the BB 50 trim kit. We have it already, it's $2995. Comes with a 44 mm Tial gate. I think I've typed this 10 times already in this thread.

Though I'm curious as to what aspect of this turbo is poorly designed for the evo. Its obvious that the boost comes up. So I'm can only guess that the exhaust flow was very restrictive.
I tested that exact unit a year ago trying a few different wastegates to resolve the problem w/ no progress. Head to head the T3 housing w/ external made over 60whp more then the Mitsu housing w/ internal gate. Been using the Borg Warner lineup ever since w/ great success.
