Question:
Why should anyone upgrade turbos? From what I am reading anyone that only plans to run pump exclusively really won't benefit from a big turbo. It seems that 350hp is the max that you can squeeze out of any setup on pump only, which is easily attainable on the stocker. The only thing you pick up with a big turbo is lag.

Someone school me on why someone should upgrade their turbo if they only plan on running pump with a 2.0l. I have a 2.3l and the more I look around the more I see that I won't really pick up big ponnies by going with a big turbo. I will get more lag and the same exact numbers that I would with the stock 16G

BTW - this question is only to spark good dialog on the pros and cons of running a bigger turbo NOT TO ARGUE XXX TURBO KIT PWNS YYY TURBO KIT

 

People are getting 420+WHP on pump from anything from a 50Trim to a GT35r. It also adds more to the curve. Instead of dieing off up top like the stock turbo does, it keeps pulling to you hit the limiter. A stock PUMP 16G Evo may trap at sat 115MPH Max, add a 50Trim you are in the 122MPH range. Race gas on a 16G Evo MAY net you 118MPH maxxed, 130+ with a GT30R, 140+ with a 35R.

 

I do understand that, but if you will not run ANY meth/alki injection or race gas what are the benefits?

 

Nrcooled are you for real. I made 397whp on 23psi pump gas. Bigger turbo than stock. You think the stock on can pull it off that easily. Dont get me wrong the stock turbo will get me good from a roll, but when I get going it will be good night. READ MY SIGNATURE PLEASE!!

 

less boost required for = horsepower.

 

You can expect 420+WHP on pump with a nice 50Trim kit, no meth, no nothing, and like a 120MPH trap or so. Go get a 50Trim. I believe that Turbo Trixx has the Best on the market.

 

I am familiar with forced induction and pros/cons but I am looking to get some good feedback.

Pros: better efficency (depending on usage), more consistant power, less temperature fluctuation, lower intake temps etc.

Cons: more lag, increased cost, more prone to kill an unprepped engine, more lag

I am personally going with a 50 trim setup so I guess this doesn't really apply to me but its interesting to look at the numbers when comparing stock vs. upgraded when ONLY RUNNING PUMP

 

600 awhp on pump, that good enough?

 

lag IS OVERRATED, I get full boost by 3800 rpm, and pulls like hell all the way to 9000 rpm

 

running 20 psi on pump on a stock turbo will not top the horsepower number of a 35R at 20 psi on pump fuel. so more hp at the same boost level on pump. have you seen how much boost is required on an 8 to make 375 whp? now, how much boost on an 8 with a 35R? both on pump fuel. to make 375 on pump, stock turbo, you'll probrably need alky.

 

No meth/alki?!!? Jebus that's insane

Link/thread/info?

 

VERY!!!!

 

Good question, nrcooled.

For starters, let's take a look at the, erm, evolution of my evolution. The picture shows the torque of my car going from stock, to stage 1 (exhaust, cam gears, tuning), to stage 1+ (exhaust, 272 cams, cam gears, tuning), to stage 3 (3071 turbo kit, built 2.0, 280 cams, etc.). All of the tunes were on pump gas. Within the next 3 weeks I will hopefully also have data on how a 50trim and 3076 perform on my car.

no meth, ha no link either, 33-34 psi on pump with a fully built engine.

 

Ultimately I think the answer largely depends on the application and platform. For a pump-gas application:
- '03/'04/'05 on a stock block would probably want to go with an Evo IX turbo or TME
- '06 no upgrade really needed

However, in my case, I chose to upgrade (bigger turbo and built block) because I wanted to be able to rev my engine higher and I also wanted better power up top. Ultimately my goal is to have a car that has an ~8500 rpm shift point with a 9000+ rpm redline. Not something the stock turbo or block could ever accomodate. In my case I also found that even the 3071 on pump gas runs out of steam too soon, which is why I'm looking at the 50 trim or 3076. The factory turbos are fairly well matched to the stock engine, and the IX turbo looks like it is outstanding. I would guess that the IX turbo will be the equivalent of a 3071 on pump gas, given the stock redline: maybe a hair less power, but far better spool.
