Question Need guidance... '02 WRX + E85 + Emissions + etc...

Hi,
Okay, so I bought an '02 WRX with some upgrades. I have since moved it to where I live, which is a mile above where it was, and here in Denver we have emissions via sniffer (supposedly visual, but I haven't seen anyone look yet...), and we don't have the same type of fuel that it was tuned on.
So in talking to tuners, I've found that I should be getting an AccessPort for my car so I can have 2 maps, one for E85 and one for 91 oct. With that, I guess I need bigger injectors.

Right now, here are the car's upgrades:
LGT/Blouch 16g turbo
Vibrant Headers
Vibrant UP
TurboXS DP/cat/MP
Stock muffler
Perrin intake
STi TMIC
STi Pink injectors
Walbro 255 FP

I am planning on having a local shop add a Magnaflow HM cat to the end of my DP to make my car clear emissions. I am currently trying to figure out exactly what that entails as I don't want to modify my DP structurally if I don't have to. They tell me that this won't adversely affect performance.

What I'd like to know is:

What AccessPort do I need to buy: are there different models available, or just one? What's with the "unmarried" vs. "married?"

What injectors should I get? It looks like I need something in the region of 850cc - are there pro's and cons to any, or are they pretty much all the same, and I should just find the best deal? Any specific recommendations?

Is there anything else I need to be able to tune my car successfully on both 91 oct and E85? I want tuning for both because I'd like an improvement in the get-up-and-go at lower RPM's (pre-spool), and I don't really see a downside to it besides the initial cost of tuning.

Any related advice is much appreciated...

Married means that it is linked to the original ECU first applied to. Unmarried means that you can toss it on any car without problems. (not an AP user though, so correct me if i'm wrong)

I have the same engine/turbo on e85. Stock modded flow fine for it. My IDC gets into the 80s.

I also tune for gas and e85, but also make a map for a "mix", something with wastegate boost pressure only and safe timing. That way if you get stuck having to put gas in w/e85, you can still drive the thing.

Read the e85 army thread for great suggestions on timing and fuel for e85. The stuff can take a lot of timing, but you don't always want to keep adding timing even though there's no knock.

Good luck

awdpirates.net is where the Colorado people are at. I would sign up there for some more local help.

You will fail emissions without the stock DP. You only need to get it done every 2 years to get your car registered. There is a thread on pirates that details mods and if they passed or failed, and even with a high flow cat, almost all people fail. They do have mobile testing stations, but if you coast through in gear, the results are tossed, and you won't get a notice in the mail.

Injectors: Deatschwerks.

My car is setup the way you are looking for. Up here, I'm running 70% IDC on E85 with DW850cc injectors. I have an APV2 with a map for 91 and for E85. Ditch the stock muffler.

I am getting some Bosch 1000cc injectors, and an AP too. My tuner told me not to buy Deatschworks for my car, and that the Bosch would be better for my needs.
Is there anything else obvious that I'm missing? Will a new exhaust make a big difference? Will it get me in trouble?
What about some lighter-weight pulleys?
What about a 3 port solenoid (not sure what that is, but I read something somewhere...)?

Exhaust helps alot look into the avo exhaust it looks really stock but has all the performance as a loud ass exhaust. Its what i run and i love it. Has a really nice rumble but not super loud.

Cobb is about same and alittle cheaper

Lighter weight pulleys are good but dont really add any power, just free up some stress on motor.
I would stay with stock solenoid

Who is your tuner?
If you want you can get a lightened crank pulley only.
GrimmSpeed makes a nice boost control solenoid that will help you maintain a more steady boost and a slightly quicker spool.

I'm asking this question since all my car info is already listed here - in the interest of making emissions here in Denver, is getting a Prodrive catted exhaust a good idea? They're really cheap on eBay, and maybe that would be a good solution without losing power? Am I going to run into problems getting to mate with my otherwise-all-TXS exhaust?
I found a Prodrive 3 port solenoid, but I guess I'll pass on that per the above post.

Other ideas?

How much improvement will I see in the performance of the car if I switch to better suspension? I currently have stock front struts/springs and STi pink struts/springs in the rear. When I roll to a slow braking stop, and finally stop, there is kind of a weird clunk/settling I feel in the rear. Could this be indicative of blown shocks, or what? I only notice it when braking to a slow stop, and not when reversing and braking to a stop.

Okay, and since I'm asking questions, how do I get my car to sound like a WRC car? I really like that sound, and mine just doesn't sound like that. Is that a function of the headers, the exhaust, both, or something else?
And is it a practical thing to have a on a daily driver whatever those WRC cars have that keep the turbo spooling? That'd be a really nice thing to have if I could switch it on and off.

I believe that I have already posted, this, you will fail emissions without the stock downpipe. Swap on the downpipe, get tested, then swap your aftermarket exhaust afterwards and then you won't have to worry about it for another 2 years.

A 3 port electronic boost solenoid will improve the car, but you will have to get it retuned.

Improving the suspension will help with acceleration, braking, and handling, but those improvements will only be helped with good tires.

As far as making the your car sound like a WRC car, I believe they have equal length headers(which will get rid of the "Boxer rumble" sound) and just straight back exhaust with antilag. Threads about antilag come up from time to time.

I don't think I've found as to how much something like that would cost, but the consensus is that it is more expensive than the car itself. Also the turbo would have to be replaced every couple hundred miles.

I dont see fuel rails or an aftermarket fuel filter etc on you list of mods. Thos will be needed to run E85 for any extended period of time. Also keep in mind at least 20% more fuel is needed to run e85 at the same level in comparison to other fuels.

Bosch injectors or probably the best out there next to the 2200 versions

Accessport is a good idea if all you want is a easy way to switch maps and easyer way would be UTEC of which would also allow for better control of timing and fuel.

Eh the fuel filter isn't required on an E-85 conversion, hotrod has over 30k on the oem filter with no problems. Everyone agrees that anodized is better but not necessary. Fuel rails are not required i believe up to around 1200cc injectors, don't quote me but i know they can handle a lot of fuel, and the correct mix for E-85 is near 30-33% more fuel which can be done most easily by scaling back your injectors. Do some more research regarding E-85, it's good stuff but definitely has some characteristics you need to be aware of.

I will be on E-85 by tonight or tomorrow depending on how the injector and pump install goes

Actually the ethanol content in Utah is E70 year round. In my experience, i added about 23-25 percent.

you can pass with a highflow cat, you will have to heat the cat up for it to pass....IE with a torch on the actual cat or do a few WOT highway pulls and then get it tested immediately. At least you will have to do this on the Cobb.....but other catted downpipes like the Invidia, Perrin, and a few others should pass with no problems as the cats are around the neck of the DP.

The OP will be tested in the Denver area. All emissions testing facilities are state run, and they will ask you to turn off the car while they scan for codes and do a visual check for cats.

They didn't care that I didn't have a cat in the DP - and the cat further back was cleaned out. I don't think they even looked under my car. They didn't know that I failed until the results printed from the computer. I guess I found a good testing facility.

They're all like that. Like I said, they are state run. The person that scans for codes/visual checks for cats, the guy that drives the car on the dyno, and the guy that hands you the print out work separately. They have no interaction with each other, and a passing result cannot be bought.

Bump for a few more questions as I'm registering my car in CO in the next week.

I'm tuned for E85. I have a highflow cat in the downpipe, and my midpipe looks as though it has a cat. I went through CO emissions a few years ago, but only the visual, and it passed. Has something changed? Why would I need to put a stock d/p in to pass now? Especially since my d/p has a visible cat....

My understanding is that since E85 burns cleaner, I should pass the sniffer test. Anybody have any experience?
