This is probably a bit different of a situation than most of you ask about. I have an Axis 2.3L bottom end with JDM V8 heads and upgrade Axis springs. I'll admit now that it was a mistake to have gone this overboard on the engine after my old 2.0 took a dump, but it is in there now. I had an SR50 on it, but that blew. I've pretty much grown out of the idea of wanting a super fast car so I have no real interest in puttying a giant turbo back on. For now it has the stock WRX turbo with full bolt on's, but also has a stock transmission. I just can't see myself spending tons of money on the drivetrain, plus a turbo and tune. I would really much rather start taking this car back to stock, get some money for my parts and use it towards buying a house and things of that nature. What I was thinking about doing is going back to stock intercooler, intake and catback and leaving the up and down pipes on the car. I'm hoping this would make it easier to tune and get the thing running more smoothly. Professional tuners are way to far away and I honestly don't want to spend the money or take the time.

I have PE800's in there right now and, honestly, they make the car run like crap. I have a UTEC and wideband, but no real knowledge on how to tune. I was hoping that if I went back to stock injectors as well as mostly all stock pieces like intake, cat-back, etc, that a standard map with corrections for added displacement would make the car run fine and be somewhat fun again.

Really looking for advice here on what to do. I keep swaying back and forth on whether to get rid of the car entirely, but I'm pretty sure if I could just get it to run better then I would be happy keeping it (love the awd in winter).

Sounds like you should be looking for a good tuner instead of injectors. If you have no local tuners have someone like pdx or anyone that does mail order tunes make you a map with the mods you have listed.

professional tuners are far away, yes, but sometimes, it is what you need to do really. How far are you willing to travel to get tuned?

Junk the PE, buy the Deatchwerks (?)spelling, and retune it. If you have the older PE injectors, they are notoriously hard to tune.

Well, I have no options in the Detroit area and the next closest would likely be Chicago. I just don't have the time or desire to put that much effort (and money) into it. Plus, the last time I took it to a tuner for a basic street tune to help get it running a bit better, they blew the trans in it. I would be horrified to make the six hour drive and have the car break, leaving me stranded.

I was hoping that I could run closer to a standard map that TurboXS gives out. If I were to keep the stock turbo on the car it is just a waste to keep those big injectors in there, along with many of the other aftermarket parts on the car. The intercooler I'd like to swap back to stock as soon as the weather allows. That little turbo just can't feed it. I have a local who wants to buy the injectors from me, so that kinda got this whole idea started. The stock turbo isn't a good match for that engine, but I'm trying to do this the cheapest way possible.

Another option would be to get some pinks and a VF turbo. This isn't what I'd want to do because of the money aspect, but it might make the car pretty fun to drive without going overboard. I'd still go back to the stock top mount I think and probably stock catback and intake. Even still, it would probably be pretty fun with that engine and up and down pipes. Probably be a pretty decent sleeper to have some fun with on the rare occurance I'm in the mood.

See, this is exactly why I want to ditch them for something smaller. Might as well get a better match for the turbo that is stuck in there and anything else should be much easier to tune. The only way I could really get the car to run somewhat decent is by going speed density. Nothing really matches right now and if I can cash out some of these parts and make it run better then I'm all about that. I'm not looking to make it super fast or race it, just want something fun which basically means driveable.

I was going to suggest that if you could bring the car to Ontario, perhaps Toronto, you could have Mike from Innovative tuning come up and perform the work for you. I know he travels for tuning also, so perhaps you could even arrange for him to meet up with you or something. Just an option. It might be a bit of a drive, but I am sure it will be worth it once he tunes your car for you.

Why not give Speed Industry a call. Tony should be able to get you setup with a good tune.

So you are running a stock car basicly, with a SR50/800cc injector map??.
No wonder it's running worthless.

At least scale the injectors back about 30%, and go from there.

I have had the same problem more or less.
I bought a PowerFC, for an v3/v4 STI, which has 550 cc injectors(which I also have)

I however thought the PFC was mapped for the standard 380cc ones, so I upped the injector size about 33%, to get the 550's running.
But as it was a STI PFC they already were mapped for the 550's.
So upping them 33% I was overfuelling the engine like hell.

c/n:

Scale down the injectors, so atleast the idle is good.
Go from there with the Utec, taking it slow, and keeping the AF Ratio on the rich side of things, to prevent Knock/HIGH EGT's

It's not an SR50 map. I converted over to speed density after the stock turbo went back on and I've also used the proper injector scaling numbers and also put in the added displacement corrections. The car is far from stock, in fact the only thing that probably is stock is the turbo. It doesn't run that horribly bad when the weather is a bit nicer, but this cold weather makes it run like garbage. My AFR's never seem that bad, which is why I just don't think I'm capable of tuning this on my own.

sell your PE's and get stock injectors.
so you're pretty much going back to "stock"
but with built motor. yes overkill.

you have 2 options
sell the motor & heads, re-coup your money.
get a true stock motor and get stage 1 map for utec.

or

try in steps to tune the current setup.

if you're tuning yourself..do you have a wideband O2?
don't just adjust the fuel map w/o a wideband.
or you could be buying another motor.

the second is the quickest remedy.
but the first you could get back your money.

I do have a wideband in the car. The thought of yanking the motor has crossed my mind, but that a bit bigger of a project than I want to tackle at this point. My main question is whether or not stock WRX injectors are going to be big enough for this engine. I'd hate to run it dry. If I could find some modded stockers or STi pinks then I know there are plenty of "free" maps out there to match up with what I intend to keep on the car, but if I can get away with the stocks I have then I'd go with that for a while.

Please give Speed Industry a call. A qualified tuner will do wonders for making your car run correctly.

Is that the former Payn dyno? I could see myself going to them at some point in the future, after I've decided on a final setup. I wouldn't be totally opposed to paying for a tune, even though it'll be $400 or so, but not until I've modded the car to where I want it. I'm getting real tired of the real loud exhaust, so I'm thinking stock catback, plus there really is no point in leaving the giant APS front mount on there for just the stock turbo, so that should come off as well. At that point an intake is pretty much useless so I might as well go back to the stock box. The injectors, at 800cc, would be huge overkill and the PE's are already very difficult to tune. Might be better to source some pinks just to be safe, but maybe stockers will do the job.

That's fine...put the car to where you want modification-wise. I'm just saying a good tune will do wonders for you.

yes, its the former Payn dyno. Tony (x99percent on here) does a damn good job at tuning there.
