Something different from Mead Engineering

2.5iSTI · 11-05-2008, 05:53 PM

******UPDATE***** 1/16/09
Well given the level of completion of my project as of current, I figured t was time to bring it to the light. Over the last 6 months Bryon has been working with me on transforming my 2007 2.5i into somewhat of a monster. It now has a EJ257 w/CP pistons transplanted in and going to be fed by a rotated GT35R setup. The road has been a long one and is coming ever closer to completion. This goes to show the extreme competence level of Mead Engineering in being able to make even the craziest projects a reality. He will also be tuning it as well. Should having it running in the coming week or two. Here are some pictures should some progress along with the custom modified 2.5i intake manifold we are using!

Updates to follow!!

Do you have a picture of what it looked loke before? What is the advantage of using a modified 2.5i intake manifold?

not sure if the 2.5i intake is the same as the RS one but apparently the longer runners are better 4 big boost

im curious how this thing is going to be tuned..opensource or a standalone ems?

I believe it is the same as the 04-05 RS other than it is DBW, but different than the other RS years. The car will be tuned with Access Port.

It looked like a stock 2.5i intake manifold with no TGV's. Granted the car still doesn't have TGV's as these are gutted and ported. The Advantage is a bigger plenum for the manifold. Why buy $1000+ aftermarket manifold when Subaru has already made an excellent designed one from factory?

mxpunk · 11-05-2008, 11:59 PM

cobbs AP works with the 2.5i's ??

id be interested in seeing this thing scaling back 800cc injectors via open source..
props for bastardizing a 2.5i!!!!!!!

Matt Monson · 11-06-2008, 09:52 AM

If this thing is going to be tuned by AP I suspect it's a full swap with WRX or STi ECU and not what most of us would consider an AFI build. Based on the heads I am seeing in the pictures, I think this is a swap.

mxpunk · 11-06-2008, 12:05 PM

^ i agree, those be dohicky heads.

the only thing 2.5i on this is the car itself & the I/M so it seems.

2.5iSTI · 11-06-2008, 12:16 PM

EJ257 block, STI Rods, CP Pistons, DOHC Spec B Legacy Heads and cams. This is a swap, I even have the 6 Speed. Did full harness swap and have a 2004 STI Ecu, so the Access Port will work. I am not sure why this got moved to the Bolt On Turbo part of the forum.

mxpunk · 11-06-2008, 05:23 PM

yea..this is def the wrong forum then, theres nothing afi about this.

fail

2.5iSTI · 11-08-2008, 11:09 PM

Projected project completion 3 weeks~!

IllNastyImpreza · 11-08-2008, 11:37 PM

so whats the definition of AFI vs swap.... the ECU its using ???

2.5iSTI · 11-09-2008, 12:11 PM

I am not really sure, but this is a swap if anything. I will be starting a new thread in the Power Bragging forum after it is finished.

VIsubi · 11-09-2008, 05:22 PM

yeah seems they like to move stuff around here..they have issues...actually I heard the intake manifolds on the 2.5i's are alot better than the RS's...I've even heard of wrx guys swapping in for 2.5i intake manifolds...pretty sweet.....well begg to be different than the rest...hoping to get my 06 EJ255 swap come january....keep my 2.5i engine as a back up....gona post picks when it get done.

2.5iSTI · 11-09-2008, 07:45 PM

PM me if you want some insight as to what all you are in store for.

2.5iSTI · 11-09-2008, 08:22 PM

Guess I can start walking all who are interested through this process. Original intentions(budget included) for the project have been far surpassed. I have learned a lot and hope that I can make the process easier for anyone else that might want to do the same. When I decided I was going to turbo my 2.5i, I read all of the threads basically warning against it and flaming any who spoke of it. Still wasn't detoured from my goals. Initially my goal was stock STI power level.

First hurdle that I had to jump was figuring out fuel control. I have seen the Perfect Power's and even though about MegaSquirt, but after a little research neither would do. So I thought there had to be a way to wire in a WRX or STI ecu. Well there is, that is what we call a harness swap. Well I did some looking and the 2004 STI ecu seemed to fit the bill best. It was setup for a 2.5 engine and did not have an immobilizer to mess with. I also located a 2004 STI Dash harness and cluster to complete finish off the interior side of the swap. One thing I did not take into account is the fact that all STI's have the auto climate control. That in itself would have stopped most people, but truth be told, it is not near as hard as people make it out to swap. Also since the dash is out for the harness swap, you have easy access to change out the a/c and heater stuff anyways.

On to the engine. The core of the engine starts with a EJ257 block. It has a STI crank and rods, CP pistons, and the heads stock off of a Legacy GT 2.5. Top it off with a custom fabbed 2.5i intake manifold. All assembled by Bryon himself at Meade Engineering. Helping deliver fuel is a set of Perrin V2 fuel rails with some 750cc injectors(temporary). Using this setup through the winter and switch out to some DW 1100cc's in the spring.

More to come.

VIsubi · 11-11-2008, 05:47 PM

well intresting no I'm not walking actually doing the EJ255 swap o6 come january so I'm jumping in..friend of mine with a 2.5i actually did the swap in 4 days..bought a wrx that had been rolled from the insurance company...for 800 bucks lo and behold..sold the tranny to another frined of mine that broke his 2nd gear doing launch's..

Venividivichi · 11-11-2008, 09:56 PM

yeah i went to Mead engineering for a stage 2 tune
very professional guys and were open and honest about everything even let me walk around the garage for a lil while, while my car cooled down.

I think mine is a little more involved.

- Auto Climate control
- Rotated 35R setup
- 6 Speed
- Every bushing made by TIC/Karboy
- Billet Pitchmount
- Grp-N Engine mounts
- Rear End lockdown kit
- 04 WRX Seats
- FMIC
- Custom 2.5i Intake manifold

So a little more than an in and out swap.

IllNastyImpreza · 11-13-2008, 08:05 PM

another reason I ported the crap out of my STOCK 98 DOHC heads.... more time to spend doing other things besides climate control wiring

VIsubi · 11-14-2008, 03:28 AM

so you kept the 2.5i intake then..I don't see whats custom about that other than the wind vavle removal or install on the intake manifold....but I hear good things about using the 2.5i intake manifold might just do that bolt on...well other than the swap I plan on upgrades also just not at one time..I still need to use my car as a DD planning on riding my gsxr while she's being gutted but don't want it to be to long.

The 2.5i manifold is not a bolton affair at all. We had to have it cut and welded to a set of WRX TGV's. The way the 2.5i fuel rails are setup(returnless), you have to replace with some type of STI/WRX varient. Well where thy bolt on to the manifold, the bolt spacing and locations are different. I believe the 04-05 2.5RS has the same spacing/bolt holes that WRX's have thus allowing you to just use their rails. So there is the hassle with that.

2.5iSTI · 01-16-2009, 11:17 AM

Here is the update. Car has been moved to finish up the swap. I was lucky enough to pickup a Perrin exhuast manifold and rotated uppipe from another suby guy that had his car there getting worked. Updated pictures and maybe a video on Monday. Looks like 2 weeks might be realistic!!!

SW00P_G · 01-16-2009, 03:21 PM

That header/up-pipe combo was mine. I'm anxious to see how that Manifold works out for you!

Goold luck with your power quest!!!

-Bryan

2.5iSTI · 01-19-2009, 03:53 PM

I appreciate it Bryan! Went by Slow Motion today and got in a hurry and didn't take any pictures. New manifold is on and I just dropped off some DW 1100cc injectors to finish off the intake manifold and fuel rail install. Now that the old manifold has been ditched and the Perrin moved in the only things left to fab is the downpipe and blowthrough upper intercooler pipes. Car will be open source tuned as well! Updates to come!
