I have been trying to make a decision on a trubo for my EVO 9 for some time now. Everytime I get close to pulling the trigger I change my mind. I recently visited AMS to have my 30,000 mile service done on my EVO 9 and Eric @ AMS spent some time with me talking about the 50 Trim and GT30R kits they sell. I never even considered the GT30R kit they sell for fear of it being to laggy for the streets on pump gas. Let's just say after speaking with ERIC I booked an appointment to have my car tuned in July with a new AMS turbo kit! I can't wait.

I want what everyone wants-a killer streetable turbo that doesn't spool @ 5000rpms. I will be using pump (93) gas for 99% of the time with this turbo.

Just looking for feedback on those with either the 50TRIM or the GT30R kit that AMS out of Chicago sells.

PLEASE NO RESPONSES FROM THOSE WITHOUT [B]ACTUAL[B] experience. I read the forums, I do the searches, I have read what is out there on these turbos. I am just looking for additional feedback from those who own and drive these turbos-especially the GT30R.

I am not building my engine. I have an EVO 9 and will have all supporting mods AMS suggests when this turbo is bolted on and tuned.

PLEASE, PLEASE only respond if you have actual experiance with an AMS in IL Turbo Kit.

Thank you, Thank you!

go with the 50 trim, faster spool than a 30r and better numbers wen on pump gas, if you would ever use race gas, which your saying 99% you will pump, but the 30r will make a little bit more power on race gas, but not much. really i dont see the point to a 30r anymore these days

 

I have the ams 50 trim and made 390 awhp on pump and 450 awhp on 100 oct. My buddy has the 3076 and he made 408 on pump. I love my turbo but I have to run 100 oct now after feeling the difference between pump and the 100 oct tune. Either way they are both great street turbos and you will be happy with either.

 

what kind of dyno's were you and your buddy on? cuz alotta 50 trims are making 420-430 on pump i thought

 

If you stick with the stock head and intake manifold, then you should be able to start spooling a 50 trim by about 3300 RPM. Full spool in 3rd gear should happen somewhere around 3700-3800 RPM. A GT3076 will spool later. Not sure how much later, but I'm guessing about 300-400 RPM later. Spoolup on the 50 trim is more progressive, whereas the GT30 series turbos are more like on/off switches.

I run an AMS 50 trim on a fully built 2.0L block, ported head, and AMS VSR intake. My setup will get full spool in 3rd gear at just before 4000 RPM. A combination of aggressive cams and the intake have whittled away at my spoolup, which is why I stated that on a stock setup it will spoolup around 3300 RPM. More info on my car: https://www.evolutionm.net/forums/sh...ad.php?t=84010 ... 50 trim info is towards the end of the thread.

That depends on the dyno. On AMS' dynojet, most Evo VIII 50 trim setups come in around 390 - 410 whp on 93 Octane. An Evo IX should be able to make slightly more power.

I think 200-300 rpms later. For more info about the 3076 check out the AMS thread regarding an evo ix tuned w/ a 3076.

 

It was on the ams dyno which is very accurate. My car has always dyno'd 20 whp lower then other cars with the same mods from day one. So you are right about 410-420 range.

 

I have a AMS GT35RL kit and I was hitting full boost @ 4500 rpm. With the VSR now I am hitting full boost @ 4800 rpm. Made 407 whp @ 21 on 91 octane w/ stock intake manifold/ TB, so you should be very close to that or better, since your using 93 octane. The lag won't really bother you as much because I was in the same boat. I plan on doing a stroker later, so it was ideal for me to upgrade my motor and not have to upgrade my turbo later.

 

what kind of pump gas are you guys using? 93 or 91. because 390whp sounds really good for a 50 trim. im just asking because i just bought a T04R that made about 400awhp on my buddies evo on 91 i know that with race gas or meth its alot more. but if a 50 trim makes 400 awhp without meth or race gas AND spools earlier. i need to reconsider selling the turbo i have now for a 50 trim. because i dont really plan on using meth or race gas

 

93 oct here in illinois.

 

Well I like my 3076. I want a 35r now, but it runs really good. I guess it's alittle give and take, but I'd go with the 3076 and meth if I was in your position. I'm doing that now and I'm really glad to be running meth with the 3076. You'll want more later. This I pomise you. You can hit you desired target in power, and with meth, you'll be able to get more anytime you want.

 

I had both AMS 3076r and 50 trim, the 50 trim spool about 200rpm sooner.
I prefer the 50 trim for a street turbo.

 

y?

 

yours is lower than normal? you have all that fancy stuff though...
