Just got the first manifolds in....
David - way to go !!!! Can't wait to see these!
BTW - Dave - if you have a sec or two - would you care to give your expert opinion on what kind of whp figures (awd dyno jet) and boost level that you feel a 4g63 can safely support on pump gas - 93 octane?? Thanks

I don't have pictures other than what is up on our website already in the prototype form.
The flange that we set this up to use is the standard TDo5H housing pattern. This will allow us to use all of the internally gated turbos we currently have. We have turbos that are internally gated that have put over 650 HP to the wheels. They will bolt on and look virtually stock appearing. There will be no other flange options for this manifold.
The entire turbo kit is going to cost $2500. The manifold by itself is going to be in the $500-700 range. The kit will include the manifold, bolts, turbo of your choice, oil feed and return lines and a high flow stainless steel 02 housing.
We haven't tested these turbos on the EVO, but have run all the different configurations on the 4g63's in the DSM's, same thing. No surge problems.

There are many different size turbo's that will bolt to this. Any turbo using a turbine housing that will bolt to a 1g or 2g manifold will work. Like I just posted above this one we have turbo's that will make up to 650 whp sitting here that work perfectly.
Pump gas whp on a dynojet. Going to depend on the size of the turbo. You could run a super large turbo to get the CFM required to make huge HP. This would make for a very boring laggy set up on a 2 liter. This would allow you to run low boost and still get the CFM in the engine. Looking at it this way you could limit the boost to 20-21 psi on 94 octane, tune the hell out of it with a standalone and cram some serious air in. I would imagine if someone wanted to really work at it you could make 500 whp. I don't think it would be fun to drive or worth the effort.

Hello david thanks for your reply
How quickly do your turbos spool up in the dsm's ? also ive run a internal gated GT30 on a evo which suffered from surge and very little boost below 4000 rpm which is not what the evo is about. Do you think your turbos will offer high power output while keeping good low down power ie a power band of around 3500rpm to say 7500rpm ? ps i don't want to use nos, i want somthing that has power at all times.
thanks gary

I assume you mean Ductile Ni-Resist and not Ductile Ni-Resist Stainless.
Ductile Ni-Resist is an austenitic cast iron with high percentages of Nickel and Chromium. It is basically considered the iron equivalent to stainless steel in their properties but does not have the same cast look. Depending on what grade you are using, looks like a good application for it.
I could probably go on about it... but you guys would most likely get bored
If you want to look at some really boring information on ductile irons, visit the following link:

Ender Wiggin, you got me, that is it. I was trying to find the paper work on my desk and had to do it from memory.
gazz, we will not use anything that surges. We have turbos we have used on the DSM already. What we are going to do is test them as we sell them. We have one of our smaller turbos that will make 475 to the wheels at about 27 psi. It spools up low, under 4,000 rpm.
The bigger hp numbers that we have generated have obviously taken larger turbos, with that comes lag. Not alot you can do about it.
One thing on a side note. The EVO is freaking AWESOME. As a matter of fact I have already made a call to try and get the new '04 RS model for my personal call.
What we have been able to accomplish with the stock turbo is nothing short of amazing. Quite a few guys have gotten in the 11's so far.
Being able to run 11.65 at 117.88 mph with a turbo as responsive as the stock piece on the EVO is incredible. My advise to most guys that really like the way the car feels down low is stick with the stock turbo and add our Staged upgrades. This will give you the great response and the top end you need. Less money spent, a more all around enjoyable car to drive.
Take care,

Hell, I'm so happy with the quality and attitude behind Buschur Racing, I'm sending David and the boys a damn fruit basket at Christmas.
Keep up the great work, guys! Above and beyond, period.

Dave,
There has been a lot of talk on other Evo boards about the Evos not being able to use regular turbos because the Evo turbos spin the opposite way. It has to do with the way the exhaust flows from the manifold collector into the turbine housing. Have you given any consideration to this with your turbo kit seup?
Obviously the exhaust will still flow into the turbine housing and spool the turbo whichever way it is designed to spin, but there maybe some power/efficiency loss?

While I am not at liberty to disclose specific details - I can say that Pruven has built a custom one of a kind manifold for its own Black Evo which utilizes a very similar turbo using the same flange. I have seen a 600 plus whp dyno sheet so I know this kind of set up can yield massive power. I am very excited to get my Buschur Turbo kit
I believe the only way you can successfully run a large turbo that supports a lot of power is by using a dual ball bearing center section.
We will have out GT L3R dyno tested early next week at the lastest(hopefully Fri). Then you guys will be able to see big power while maintaining a fast spool.

Actually, I have noticed that recently Al has been a little more, how do we say, people friendly with his choice of comments. Good move Al. I can respect someone that can admit to his mistakes or inexperience in certain fields. I for one work on cars for a living and I constantly read guys making stupid comments or false advice. At the same time I always find myself learning from more experienced tuners/racers.
