Any Buschur BB GT30R Turbo Kit owners?

To the people who have the Buschur Racing ball bearing GT30R Turbo Kit on their evo's, i was wondering if you guys could give some feedback.

The $3100 pricetag seems VERY tempting, but I just wanted to know what you guys thought about it.


How much power are you guys making? How much power can be expected?

Any feedback is appreciated.

Thanks!!

I have it and so far with only one pass (60' time was 2.1 b/c it spun so bad I had to back out) and the mph was 121 on 25/26 pounds of boost. I just got the HKS DLI-II on so I should be bale to turn up the boost.

What was the time on that? I know the crappy 60' slowed you down, just wondering. What fuel were you running at 26 psi? Pump with alcohol injection? Race fuel?

I am asking all this becuase I just finished putting in my Buschur GT35R, and I have the alcohol kit sitting in the living room. I am waiting on the alcohol kit until Dave has the new dyno set up and ready to go. Then I will get a full on tune for my AEM EMS using the alcohol kit with 93 octane and see what Dave can do for me

The tune is critical with the larger turbos. The combination is too. The companies you see actually turning in killer times have good control over what their customers are doing as far as tuning and such goes on the cars.

Looking forward to tuning your car fourdoor. Our building is up, not finished but under roof and we should see our dyno soon, they said after the 4th of July.

BTW, the GT30R on the last car I tuned made what I consider a disapointing 450 whp at 28 psi. The few GT35r's I have had a chance to tune here have made over 600 whp, for the difference in lag between the two, my opinion right now with what is being offered, is to go with the GT35R.

Hey Dave,

Did you check out my "It's alive" thread? https://www.evolutionm.net/forums/sh...d.php?t=146987 I was wondering if my spool up numbers (16 psi by 5000 RPM, 18.5 psi by 5,500 RPM) are about the same as you have seen on other cars. I am really amazed by the transient response (re-spool after a shift). Looking at past data logs from my old EVO 6.5 TME turbo on a tubular header compared to the new setup, this huge turbo re-spools just as fast as the stock sized turbo with light weight titanium components!

One thing I noticed was ignition break up at high RPM with 20 psi indicated by the AEM EMS. I will swap out the plugs and see if that helps. What plugs would you recomend?

Thanks,

Keith

I just ordered the gt3076 last week from your shop and have some questions. the reason i went with this turbo is because i live in an area that is 6000ft above sea level. is this a good reason to go with the gt3076? or should i have stuck with the gt35r and live with the extra lag?

i also got the alky kit and was wondering what kind of power to expect from 91 octane and custom dynoflash? is 500whp possible? the reason i ask is in your post you said you were disappointed with the results, was that tune on race gas, pump gas or alky and pump gas? what would the difference be using 91 octane, alky and custom flash between the gt3076 and gt35r?

Thanks for chiming in Dave!

The evo you tuned with the GT30R, what other mods did it have? What did you use to tune? AEM EMS?

I'm honestly looking to net ATLEAST 450whp on 93octane with the GT30R. So i'm interested in what other mods that evo had.

Since you said you were dissapointed with the 450whp, what numbers were you expecting to get w/that turbo?


Also, is there any warranty on your manifolds incase they crack down the road?

Thanks!

I ran a 12.01 with a 2.1 60' time, that should put me in the 11.5's to 11.6's with a good launch ( I am usually in the low/mid 1.6's). I ran that time on pump gas with alky running 25/26 lbs of boost. The turbo really seems to wake-up with 28/29 lbs of boost so the 1/4mile times should be pretty interesting. I put the DLI-II on the car and will do some testing this week to see how it does on high boost now (I was getting bad break-up at anything over 27 psi).

I am getting a little ignition break up at 21 psi, but I am still running the stock spark plugs that have been in the car since new (26,000 miles) and stock wires. I would like new wires, but have heard bad things about fitment on the magnecores... what wires are your running?

Later,

Keith

Keith,

Thanks for all the good information you are posting up!

The ignition misfire doesn't surprise me at all. Common on the EVO's as the HP levels go up. That's why you see so many different ignitions out for the EVO's.

Couple of solutions, one re-gapping the plugs. Plugs make a HUGE difference in the EVO's when it comes to misfires. The stock plugs and the BPR7ES's work the best. Gap them down tight to around .022. This may take care of the misfire.

We have our COP's for the EVO's done, very simple and clean. I have not tested them on a real high HP EVO yet as just a COP. Our COP with an additional ignition box on it though has proven itself to over 1,000 hp, yes, 1,000.

I put BPR7ES's in last week and gapped them to .023 and it did seem to help, but this weekend I put in the DLI-II with Magnacores and regapped the plugs to .028. So far I am very impressed with how the car pulls, mid-range is very good (seems smoother and pulls harder), top end is nice and smooth now with each pull being very consistant in power. Low speed throttle response is much better now also. So far I would say anybody running more boost should look at beefing up the ignition system.
