BTW, as far as I am concerned the stock computer with a flash is NOT exceptable.

Anyone that wants to compete against me in tuning I'm up for proving this. Just bring your car in with a flash on it, tune it and then we'll put an EMS on it, if I can't beat your numbers you can have the AEM free.

This applies to a car with a larger turbo than stock, atleast a 20G.

The AEM EMS has proven itself time and time and time again to make big power over what we've been able to make on the stock computer.

Don't ask me why, I don't know. I am a dumb redneck, just ask anyone.

Damn it David, how can those of us who knew from the beginning that the 20G-LT was the right one, ever expect to stay ahead of the doubters if you keep posting good stuff like this. Some of us just know, 'If Buschur Racing makes a statement, it's just gotta be true'. That's not being blind, it's being smart on our part. Great job as usual.

David do you have any pump gas dynocharts of your 30R series kits? It seems to me that this turbo is a huge comprimise, 20 psi at 3500 rpms is about what a 30R will do correct, however wouldnt a 30R put down a ton more power and tq on race gas?

Nice job! I could not agree with you more. This turbo makes the car a beast for the street yet still remains very streetable. Hopefully soon I will be able to get retuned to the turbo and injectors and post some fantastic numbers aswell.

This is what i'm talking about! Great work david!!! This car should be close to 400whp on a dynojet, that really good considering all he did was just a turbo upgrade. I'm waiting on my 20G-LT with ported tubine and 02 housing. I cant wait to get this put in and installed!

First off I would like to thank David for his time and knowledge. Second there is not to much for me to add other than how the turbo drives and responds. The data David has posted now and all along is no lie this thing really performs!

I would really like to address a couple of things. First, I cannot believe how hard this turbo pulls on the top end. Very smooth and linear, I am truly impressed! It feels just like the stock turbo while your just driving around town. The 500rpm difference in spool up isn't even noticeable. When the Green-LT hits it hits hard! Just to give you an idea, my 3rd. gear now feels like 2nd and 4th. feels like 3rd. Very strong! This is obviously on race gas.

Second, The boost issues will be taken care of over the winter while the car is in the garage. As David stated before in many threads the Green-LT does not fall off to 19psi at redline. I briefly got a chance to drive on pumpgas. I am even more amazed. The posted dyno graph does not do this thing justice. Once again power on demand with no lag and great topend. I find it hard to shift at 7k it comes so fast now...I really think this is just retartedly fast on the street. From here I can't wait to add the ported parts and see how far she will go on pump. Although I am very happy with the current power.

If anybody has any questions, or if I did not include something you would like to know more info on, feel free to contact me and I will try my best to answer your questions.

It will now be a long winter to wait until the tracks open up

Thanks for reading,

Eric

HELL YEAH! I order my 20G-LT to match port the tubine with the 02 housing from Burschur racing. I can't wait man! alkjdflsldfjalkjsdf

Yes, I have some pump gas charts of a few 30r kits. The 3071 gets stomped by this turbo. I wouldn't recommend it over the Green/LT at all. The 3076 I have never been a real fan of. The 30 series we run/sell is the 3065, this turbo is a very small step under the full GT35R.

Making 380 whp on the 3065 on pump gas we've done but it is getting up there. Also you loose a ton of power under the curve, so on pump gas I'd say this turbo will stomp even our GT3065 and be more fun to drive.

As the boost goes up, of course the 3065 will stomp the Green/LT turbo. Jarrod's car for example made 505 whp on C16 at about 30 psi of boost. He trapped 131 mph with it already at FULL weight and on 18" wheels.

Dave I just bought an LT, S/S O2 housing and Install kit from you. Waiting for it to arrive now. My main problem is the lack of any dyno facilities here and the ridiculous price for C16.

I run an Evo 6 RS2 with Walbro 255 pump, ARP con-rod bolts and head-studs, Tomei Poncams, OEM downpipe (<--That's how I bought it.) and 3" catback.
Yup I know that I have to fabricate a custom 3" downpipe to install the LT in the Evo 6.

To work around the C16 problem I propose to use a Water/Methanol system. Which do you suggest? Any suggestions for tuning for AutoX on "93 pump" with a reflashed ECU?
I read what you said about not using a reflash with the LT... (with C16 I assume?)

I need ballpark data and any other advice available for this new combination.
Injector size?... spark plugs?... whose re-flash do you recommend?
Your suggestions will be greatly appreciated.

Hi Nix,

Sorry I don't have any suggestions but could you throw a thread up when your done the install and what is needed. I have an EVO 6 and I was thinking of getting this turbo.

TIA

To add some to this, the 3071 flows a good deal less air than the Green/LT does, so Dave's point on that is accurate. The 3076 will move 52 lbs/min, about 3 lbs over the Green/LT. In reality, I have had a very hard time finding logs from poeple moving more than 50 lbs/min on that turbo even on race gas and high boost. I'm not sure why that is, but that is what swayed me from going that route to trying this turbo to see if my suspicions about it's airflow would turn out to be correct. Considering that this turbo spools up faster than the 3076, Dave's comment about the area under the curve making the LT the more usable option makes sense. The 3065 makes a compromise on the turbine wheel but still runs the 35R compressor wheel, so I personaly have a hard time even considering that a GT30 series turbo, whatever it's name may be. It's a full 13 lbs/min larger than a 3076!
When you add bolt on reliability/stealth to the mix, I am happy I went this route.

The dyno chart shows a ~500 rpm change in spool up, but on the street I can not duplicate this at all. Making several runs to account for run to run variations, the LT is always RIGHT behind the stock turbo, and occasionally it seems to reach full boost sooner. On average, it's VERY close to the stock turbo. From a butt dyno perspective, I really can't "feel" any extra lag. And as Eric said, the charts probably don't do it justice, the extra pull on the top end is just mean. And the midrange is just as strong since it hits full boost at the same RPM as the stock turbo did. The airflow charts I posted will illustrate this pretty well. A very nice power band indeed. And this is very important for street cars. I run at the track at least one night a week, and attend all of the local Import events, NOPI, and the Shootout every year, but street performance is still important to me, especially after taking my 2g about 10 steps too far for a daily driver.
