I have a GT3076 and it is a pretty good turbo for guys that run race gas occasionally. My car hits 23psi, in 3rd gear, by 4300rpm. If I could do it all over again, I might of gone w/ the GT3071 for the faster spool.

As for power gains, I gained 70whp over cars that had cams on pump gas. As for 1/4 mile performance, well, I am not very good at it so my times suck. As a comparision, I gained 4mph over my race gas run w/ cams on the stock turbo w/ pump on the GT3076.

I highly recommend that you find some EVO owners in your area that have upgraded turbo's. That way you can find out which one you like the most.

 

No problemo, I always say houston for FP to my friends cause most people do not know where Mckinney is...but on evom I have to be exact The way it should be.

 

stock...

 

wait to see dyno numbers on buschers 21g stock turbo upgrade, but ive heard good things about the rnr's 50 trim with equal length

 

AMS 3076R... 'nuff said.

 

No doubt... I would gladly put my stamp of approval on the AMS 3076R. Granted I'm biased but this thing has simply amazed me. It spools up faster than my buddies WRX w/ a 18G and yet is quick enough to.. well I can't go into details, but it has beat a Cobra that went 11.7.

I've even played around with it on the Auto-X circuits. Granted I wouldnt call it an "Auto-X turbo" but it does rather well. When I need power (boost) its there and I'm not left waiting for a freight train of power to suddenly be on tap. Its fairly progressive and provides a pretty linear surge of power that does not stop until 8000RPM (where I happen to shift).

Even at 6200ft above sea level this thing will hold 28-29psi to redline. This thing really is no joke.

 

Sound like a winner, but what other work do you have done to your car?
Fuel pump =
Clutch =
FMIC =
Injectors =
Stand alone =
Boost guage =
Axel upgrade =
etc..........

Are there some dyno graphs of this setup?

What would you estimate the worth of your mods as it stands now.
I have Buschur stage one and two currently, but I am looking for something with a lot more zing'
How does this compare to the BR 500 and BR580 turbokit?

 

does AMS sell off the shelf Garret turbo's, is the turbo modified in any way?

 

the BR500bb (ball bearing option) is a 3076R turbo. The Br580bb is a 35R turbo. They sound like nice kits.

 

I've got alot more money in my setup than need be. Everything I do have does serve a purpose in the greater scheme of things. My car's not quite finished yet, but I felt it was at a point that I could "pause" and bring other areas of the car up to the performance level of the motor. Funny you mention you're at Stage 2. Thats exactly where I was when I bought the kit and the other associated parts that I currently have over the basic Stage 2 parts. You'll definately will have some more ZING. I promise you that.

I'd really prefer to not go into too much detail about what may make either Buschur or AMS kits superior to one another as that's asking for flames, especially coming from someone who might be viewed as biased. Simply put however... I think they are both solid kits with certain advantages over the other, but you will see results from both. I just happened to view the AMS kit as more favorable for my needs/goals. I would also have no problem running a Buschur BR500BB on my car either.

 

I'm afraid you're going to have to talk with AMS regarding those questions. I wouldn't want to step on anyone's toes at AMS.

 

What about people who don't want to dump $2k + for a kit. Aren't there any bolt on options besides Buchur's 21G or TME 6.5?

 

I actually opened a topic talking about the same issue. I drive a EVO 8 MR which I believe it comes with a 10.5 hotside and a bigger rounded 34mm flapper. Anyway my car spools pretty damn quick, I improved the spool up by installing the Works3" Downpipe and Greddy Cat back.

Moreover I purchased a set of header(not installed yet) and I am eager to buy the Works o2 Hosuing as soon as Works sells them.

Last but not least I am calling Forced Performance tomorrow to see if they can swapp my stock shaft/wheels for the titanium ones plus I want to get the stock turbo port and polish.

I am a guy like you, I HATE turbo spool, I had a terrific experience with my ex WRX and huge turbo and I will never get a setting like that ever. My WRX was quicker driving in town with the stock turbo than with all the crap that I put after(UTEC,PE650CC Injectors,Fuel pump, tunning and FP18Gported and polished).


Believe me, the stock 16 G turbo has a lot of potential, I am maximizing all the juice the car has. I am currentlty running 12.6@107 in Tucson at 3100 elevation, daylight and hot as hell(I just run it in memorial weekend).

Don't just go and spend a lot of money in a Turbo Kit, you maight be disappointed after all (that happened to me). You described yourself identical to me, I love quick spool of the line and specially good response on any gear and driving in town. My WRX with the FP18g rated at 605cfm@14psi use to make my engine drop rpms like crazy when shifting, it was not worth the extra 2mph trap speed.

You must find the balance between better spool up and greater top end, this is achievable optimizing your stock turbo.

Try what I told you:

Downpipe
catback
possibly port and polish your stock turbo
Headers
o2 hosuing from Works(full 3")
upgrade air filter

my .50c

 

Fuel pump = Walbro 255
Clutch = Exedy Twin Disc
FMIC = Injen (including piping)
Injectors = 640cc
Stand alone = AEM EMS
Boost guage = DEFi BF
Axel upgrade = None
etc. = HKS Cams (264/272), Adj. Cam Gears, HKS EVC V Boost Controler, AMS Fuel Rail.

 

I think vishnu is working on something that bolts to the stock manifold....?
Keep in mind the GT series turbos alone are in the $1,300 dollar range. Plus you still need intake and exhaust plumbing plus possibly external gating. I think there is also another one...ATP maybe...they have a bolt on kit. With this one though, ive heard a few good things about it and more bad things...so do a thorough search and make your own decision.

Other turbos that just replace the stocker? none other than the 2 you listed to my knowledge.
