Default Udate on my Baja STI project, check it out!

Boys, here is the outcome of the Baja STI upgrade. The VF39, STI TMIC,
and Walbro fuel pump ave been installed. The ECUtek reflash will be this Friday. Before you comment on the reflash (I know some of you endorse the
piggyback), the 05 ECU's base map is reflashable back to the ECU
without leaving a trace that it had been flashed. What my tuner will do is save a copy of the base map to be re-loaded in time for the smog. Anyway, Friday is the moment of truth.

Here are some pics:

The TMIC is a direct bolt on, the original bracket will accomodate the STI TMIC. This baby went right in. It took me longer to cut the gaskets.

What gaskets are you talking about? I've had my TMIC off many times and there are no gaskets. I just bought an Avo TMIC and that's going to slide in like butta. Well, I have to get it in my grubby paws first.

I keep telling myself that this that or the other is the last thing I'll buy and there's always just one more thing to go. I swear, after the new fuel rail, injectors, fuel pump and bigger turbo, I'm done! Well, maybe after I lower it, throw in the big brake kit, and a few other minor things, I might be done.

Aw, I'm just B.S.-ing, My wife would kick me out of the house. She's already annoyed about the two motorcycles...

I think he is referring to the stock recirculating valve (by pass or bov if you will) on the front of the tmic. the Stock tmic has more of an inverted diamond shape with studs that stick out of it. The STI tmic requires bolts to thread into it and the gasket is more of a diamond shape and flat. Stock is more of an o-ring style gasket.

Glad to see that some one has now done this. Looks good and you will be surprised when you get your new ecutek ecu in there. I have this same set up on my car. Boost is going to be somewhere around 17-18lbs most likely. Are they bumping the rev limit up as well as adjusting the avcs to sti specs? What other mods do you have on the car? A DP will make a huge difference in hp!

great stuff wikid!

The Baja hoses connected up to the TMIC? or did you need some from the STI?
Do you have a comparison pict between the TMICs?
Are you running the stock Baja programming currently with all of your mods? or is it an adjusted map for your exhaust setup?

LOL! DRNWAGN is 100% correct since he went through the same crap. The 05 Baja BPV has a rubber seal vs the STI BPV uses the paper gasket.
Instead of paying top dollar for the subaru gasket(aside from waiting for the special order) so I decided to just make it. The same way went for the y-pipe elbow.
Yep, wives are always in the way. Luckily, she doesn't know about my mod money from the parts I sold that came off my WRX.

According to Mike W. from Grouppe-S he will be using as base a map from a forrester XT that have the same set up as I have. I believe my Baja will be the first around here in the bay area.
Not sure of what will be upped or modified. Al I know is he will dyno tune.
Our goal is ~260 maybe 265 HP on the Mustang dyno. I'll have the details tomorrow.
As it stands, I have the random tech 3" TBE, Helix uppipe, and Walbro pump.

Baja hoses needed to be removed and replaced with STI hoses. Keep in mind that if you are going this route to get all of the STI hoses otherwise you're hosed J/P! Anything is possible. I might I dont recall but I did shoot some pics.
Anyway, I'll take some just for you ;-)
Right now it's stock and the ECU went in limp mode at only 10 PSI max ( i Actually loss a little performance vith the VF39 installed) but I don't care since I will go with the reflash which will work with all my mods.

There you go, now you have added to your goal LOL! Education is much more important than modding your car anyway. For an old dude like me hehe I'm sick of school.
Seriously, You'd be surprise on how much I spent on this project. Less than half of my WRX mod.


Well, wish me luck guys and I'll do a write up on the result tomorrow and maybe a vid clip of the dyno tuning if they let me.

Hey Wikid,

What do you think of the Helix UP? I want to put in a catless one on my Baja, just not sure if I want to go solid or flex. I was thinking Crucial, but they are out of stock, and Helix would save some $$$

I have had a PDE up pipe on for over a year now with no problems what so ever. I was trying to get a flex version but just about everyone was out of stock at the time of purchase. i think that either way you will be fine.

Can't wait to see your numbers. i am hitting the dyno tomorrow for the first time. I will post up some numbers on Monday most likely. Shooting for 280+. Both cars (fxt/baja) have the potential to make alot of power. The trick is finding the parts that fit due to our having different chasis than the wrx platform and companies that want to take the chance and produce products that will work/fit better.

Good luck on the dyno!! i'd love to hear the dyno run clips with the exhaust at WOT.

maybe gruppe-s can dial you in and finally maybe someone will offer a power package for Baja-T owners.

Just got home from the Mach V dynoday/open house! I managed to pull 295hp/299 tq. Not bad. I did better than I thought but I was really hoping for 300 as that was the goal with the whole build. But it is close enough for now. So there potential is there guys!

DRNWAGN -- I didn't know there was an open house today, I would have swung up that way for a baseline dyno run. still a nice pull!

You really need to keep an eye on the Mid A section. This thing was HUGE! There had to be close to 250 cars there and 95% of them were Subies! Dan (Mach V) said that they will be doing another dyno day in about a month. Cost is about $75 for the dyno time (about 3 runs) and another $25 for A/F monitoring if you desire! You would have been the only Baja there! I will post in this section the next time I see that they are doing a dyno day!

Guys,
sorry for the late update but bad news... Mike could not flash the Baja ECU because it comes up with an unknown ECU type error in the process of flashing.
There is still hope but he has to send the rom file to ECUtek to have itupdated so the that my ecu can recognize the rom file that is being flashed. Hopefully this Saturday it will be available.
Stay tuned!

DRNWAGN , did you guys have a similar issue wit your Forester? Do you have an 04 or 05?
