Apparently, the 20g-9 does not surge. That or the WR might be a good upgrade for cheap.

 

More than likley you'll need some bigger injectors.

 

The 20g-9 might do the trick, but I'd call Buschur on that one. I do not know if they've run it on a 2.3l yet.

Of course you could also go with a small GT series turbo ... I hear a 3071/2.3l combo is pretty devastating ... Ultimately it will boil down to how much $$$ you want to spend and what kind of results you're looking for.

With a bigger turbo you will definitely need bigger injectors. Even with the stock turbo on a 2.3, I'd probably go with slightly larger injectors (660-680 cc), since you will be pushing the stock snail to its absolute limit, which is pretty much where the stock injectors also start maxing out.

The stock turbo on the 2.0 EVO's is larger than the stock turbo on the 2.5 STi's, so if I was sticking with the stock turbo I would look at the EVO's stock boost curve (aprox 20.5 down to 16.5), and the STi's stock boost curve (Max boost 14.5 psi) and split the difference between them to get peak at 18 and taper down to 15.5 (if I was being conservative). Less conservative would be to peak at 20 psi and drop down to 16, but that would be pushing the stock turbo pretty hard.

noob question -- what's a spun bearing?

EDIT -- sorry, just found this post

 

Like many have said, I would strongly recommend a larger turbo. The factory OEM turbo is perfectly matched to the 2.0L engine and a larger displacement will make it spin up rediculously fast with even less top end power than it has now (imo).

 

not sure when you are getting the motor but i'm heading to Ohio on friday to get my buschur 2.3L stroker, and i will be running the stock turbo on it. I will repost how the turbo acts with the new motor!!!

 

I just got the money together for the stroker so I will be getting it done next week!

I'm getting excited but also nervous since this has happened so quick I just don't feel that i know enough about what i am about to get into!

 

could u run a Flash ecu with a 2.3ltr?

 

I talked to AL about my flash and he told me that I would have to get a custom tune with the 2.3L stroker. He doesnt have a mail in flash for the stroker.

 

oh yeha well i fig they wouldnt have a MAIL-IN flash, but i was wondering if u could work a Flash it to work wit the 2.3ltr thats all.
dont know which one i would go with. the Flash or AEM

 

I think i'm going to get the ECU+

 

OH ur in Greensboro? Im in Charlotte. Its nice to meet local people. yeha im working on getting a AMS 2.3ltr.

 

I am also going to do the same thing. Tuning it so that the turbo doesn't work hard should be relatively easy to do. The torque you will generate should be ridiculous and easily over 400wtq.

It's a sleeper look! Everything stock except the stroker kit inside. It should bust a lot of ***** and easily be a mid-11sec car.

Hi,

A 2.3 motor with stock turbo will be great for daily driving but not for any top end power since the turbo will run out of air with the increase displacement. Also, you will want at least 720cc injectors to compensate for the increase air flow. We have the Helix Denso injectors for a great deal only $365 shipped.

As for the tune, you can get a reflash to run the stroker.

Thanks,
Tom
