I have a 1995 GSX, It's already really upgraded, has a full 3" exhaust and lots of other mods done to it.

I want to know what the best turbo for the buck will be.
I am going to be looking at getting close to 400WHP out of the car. [on pump gas]
Which turbo will perform the best in that range?

I was looking at the MHI Evo 3 Big16g, which seems like an awesome turbo, any reviews on this?

Also are the 272 Severe competition cams any good?
Are there any better ones I should look into?

SEARCH around this site. Both of those components have been around since the beginnings of DSM tuning. They are proven parts with probably hundreds of subjective reviews out there on them. Put in some effort, look at the options that are currently available and then decide.

Sorry, yeah I know it's my first post and all.
I was just wondering if that was my best bet as far as a turbo, and if those cams were going to be my best bet.

I wasn't 100% sure, I already searched around LOADS on turbos, and I figured a dsm forum would be the final place to ask..

Do you have any experiences with this turbo?
Also, will an eBay FMIC perform just as well as a greddy FMIC?
Or is a eBay FMIC a bad choice?

Evo3 is an AWESOME turbo. It's reliable, proven, and a decent price.

I'm going to PM you more info on the evo3 :)

Name your other mods too.

Thank you sooo much.
Well, there is a countless number of modifications done to the car..
A few off the bat is a Full 3" greddy exhaust, downpipe, greddy blow off valve, k&n intake, boost control, turbo timer are just a few.
I have 550 injectors and a 255lb pump waiting to be installed also.

center welded differential, port and polished head,

There has been some debate on the topic but in general I would say it has become accepted that the ebay FMIC in either a DIY setup or the SSAC is alot of bang for your buck.

What are you goign to use to tune with?

With your car being a 1995 I'd recommend DSMlink. 550 are tiny and NO reason to ever run that small of injectors with dsmlink. 880's would be sufficient for anything about 20psi and below 30psi (50and 60 trim varient turbo).

A good call when installing the 255 is an adjustable regulator. This however isn't always needed as you will overrun your stock fuel pressure regulator a idle which will be, if under 400whp, your only discomfort. No ill effect will come on at WOT with no regulator.

Also forgot, I have a S-AFC. Will that take in place of getting dsmlink? and are 550's really that tiny?

So wait, what are you recommending I do for the fuel pump?
Not do it?
Or just get a regulator for it and run it all the way when I am racing?

S-afc is cool but I've personally never had one. I've always stepped up and purchased DSMlink as almost my first mod.

Yes 550's are tiny if compared to say 1000cc. For 400whp or higher boost on an evo3 you'll be maxing them out with no room for improvement.

If you have the cash just get a regulator.

I just wanted to state, before someone comes racing in, that not installing a regulator isn't life or death if you install a 255. You'll see that alot on thread around here. Lots and lots of hearsay.

I don't really have too much spare cash.
On a scale of 1-10 how nessicary are they?
how much are they?

Also, the guy above me says there is no way of me getting that much hp out of my car with that turbo. Think that's true?

On a scale I'd put it at a 4.

Many people have gotten into the 11's on the evo3 turbo. The statement that 400whp isn't achieveable is false. There have been numerous effiecent setup that have made MORE then 400whp on the evo3.

If you goal is 11's on the evo3, it is achievable with some effort.

I would love to have an 11 second street legal car.
And about the DSMLink thing, how does it work? and do I really need it over my S-AFC ?

It is just a much easier interface to tune with that gives you infinetely more control and has a built in logger among other functions. The inital cost is a little steep but well worth it. If you can afford it get it - I wish I had.

For a 400whp setup, a 16g is just not the way to go...The people who have made that kind of power with an EvoIII are using FULLY BUILT motors, sheetmetal intakes and on a very aggressive C16 tune

I DO think that the EvoIII is a perfect turbo for you, however I think your goal of 400whp on pump gas is a little over the top...Experience 300whp (easily done in a fully supported evoIII setup) and then decide if 400whp is the way to go

If it is, its time for a 50trim or larger sized turbo

As far as injector size, on an SAFC/Eprom/Wideband tune, I ran 560cc injectors @ 20psi daily on pump gas and 25psi ish on race gas, which was good enough for a 12.7 on the stock clutch and baby shifting 1st to 2nd gear

The same day, we took my other buddies full weight 2g gsx auto to the track with his basic EVOIII setup....On 550cc injectors, he still managed a 12.1 ET, which is more than impressive

As far as for 400whp you NEED dsmlink, I disagree...I will be running a fully supported PTE SCM50 setup on the new talon, tuning via an SAFC 1 which I am very accustomed to. I run 680cc injectors and a custom chipped Eprom, and altho Im not sure I will hit 400whp, I do plan on running 11.90's on pump gas and I don't see the SAFC being an issue at all...My custom timing map is set in the chip, and the eprom is already set for my maf/fuel compensation and all the extra neat stuff LINK has like 2-step launch RPM and Raised Rev limit, no Fuel cut/Phantom knock, etc etc

Its not that Im trying to talk you out of buying LINK, only informing you that with an EvoIII setup, tuned with 550cc injectors and an SAFC (18-20psi pump) I think you will be MORE than satisfied

Go on over to http://www.dsmlink.com and read up.

My favorite part of dsmlink is there is no evidence that you have a tuning system.

S-afc will do but it's not the most efficent way of going out tuning. Not saying it horrible just not the best thing to use.

I will agree with Chicago that if you do stay with the safc, 550cc injectors will do. With dsmlink though 550 are just as easy to tune as 1000cc.

The way I upgraded I looked ahead to the future. I personally wanted to see my turbo as the bottle neck and not my fuel system, clutch, and tuning. My interior is also clutter free with NO gauges at all. DSMlink logs those parameters when needed and gauges, other then stock, are not needed. AFC just doesn't work for me.

I did run my best time on my evo3 with 110 race gas but I was on a stock flywheel, 2g manifold, stock cams, and stock 2g throttlebody. It had way more in it. If I don't end up selling my evo3 I'm going to throw it back on for shits'n'giggles just to see how good I can run with the 2.3L motor.

So you think with 300AWHP I can get into the low 12's?
I think that'd be awesome if I could do that.
