Well here goes nothing. Fellas, there’s other way to say it…
I bought a Subaru.
Here’s the skinny skinny. It's a '98 Legacy GT.
http://i1156.photobucket.com/albums/p569/Jason_Kroening/Facebook/Cover%20Photos/471922_10151855250050523_437942643_o.jpg
The motor has been swapped with a hybrid consisting of an EJ22T shortblock (Subaru’s only closed deck block to date.) This block comes out of a 90's turbo Legacy. The rotating assembly consists of stock EJ22T pistons, STi rods (Nearly identical in size, just beefier than the EJ22T rods), and an EJ22T crank to keep the stroke (75mm) the same. Up top…I mean, on each side are stock rebuilt DOHC N/A EJ25 heads. These are a huge upgrade from the SOHC 2.2 heads that came from the factory. They're not going to net me HUGE hp gains, but they should help low end torque and top end flow. Intake manifold and TB is off a WRX.
For a turbo I'll be using a JDM twin scroll VF37 that comes stock on the JDM STi. I really don't know too much about these to be honest. From the people I've talked to, it'll spool quicker, and hold top end power better than a 16g. I've read through multiple build threads with people making around 300awhp with these. Perfect for my current power goals.
For fuel, I am planning using stock STi injectors, an adjustable rising rate FPR, with a 255 in the tank. Nothing serious, because at this point it doesn't need to be. They've been sitting in my garage since last year, and I'm sure the nozzles have collected dust inside them. So before I use them I think I'm going to have them cleaned, and flow tested. Flow should be right around 560cc at stock fuel pressure. (Self note: Rising rate FPR inceases at a rate of 1:1)
I’ll be tuning with Opensource on an ’03 WRX ECU. This will allow me to tune, and flash my ECU via laptop. No real reason for using this other than it seemed like the most cost-effective option, and many people have had great success with it.
It’s a 5-speed, but it’s a trans from an Outback. Shifting involves more searching and hoping, rather than rowing through the gears. That coupled with eco-gears and no aftermarket support means I’m working on sourcing a late model WRX 5-Speed. Ultimately meaning I’ll have to change from a cable to hydraulic clutch setup, but it will open up more aftermarket support. To give you a sense of how tall my gearing is, my final drive is 4.11. Redwood tall gearing FTL! Once I find a transmission it will get upgraded (Maybe even with a few PPG gears) to handle future modifications.
In the future, I think I want to build this in to something I could potentially road race (Gutted, relocated fuel cell etc..). There's definitely another motor in store for this thing. But, I haven't thought much about what that build will entail. Most likely something around double the power of my current goal of 250awhp.
Having the ability to use 02-03 WRX suspension components I have tons of choices for suspension. Haven't decided on what, since the stock WRX suspension installed works just fine. It gives the car a pretty good stance for stock components. I'm using WRX hubs as well, giving me the same brake upgrade choices as any WRX owner. I think it's pretty sweet to be able to use late model parts on a car 15 years old! The car needs brake attention badly. The pedal is very soft. So once spring time rolls around I'll throw on SS lines, and possibly upgrade to STi calipers with an aftermarket street pad.
Current setup as of 4/1/2013
-EJ22T block
-EJ22T crank
-STi rods
-EJ22T pistons
-EJ22E head gaskets
-EJ205 heads
-EJ205 cams and valvetrain
-EJ205 intake manifold
-Side feed TGV deletes
-EJ205 throttle body
-STi yellow side feed injectors
-Walboro 255
-VF37 twin scroll setup
-'06 WRX TMIC
-TiAL bov
-Catless twin scroll up pipe
-Catless downpipe
-3" exhaust
-Grimmspeed 3-port BCS
-AEM UEGO wideband
-Rom Raider tune
-'03 WRX ECU
-'03 WRX gauge cluster with '04 WRX bezel
-WRX power steering pump/lines/reservoir
-WRX alternator
-Battery relocated to trunk
-'01 Outback 5-Speed transmission
-4.11 rear differential
-Short shifter
-WRX flywheel (Possibly going with a lightened flywheel)
-Clutch undecided
-WRX clutch and brake pedal assembly
-WRX front subframe
-WRX crossmember
-WRX hubs
-WRX axles
-WRX suspension
-WRX control arms
-JDM 1-piece projector headlights
-Rusty green body
-Stock Legacy GT wheels
-3 flat snow tires
Now, for what’s going on below.
For me to be able to tune with Opensource I need to run a WRX ECU. What I have to do is remove the engine related wiring of the WRX harness and merge it with the rest of my Legacy harness. It sounds like a mess, and honestly it can be. But I don’t see why people refuse to try it. Once you isolate the different parts of the harness you need you remove everything else. The pictures vaguely show how I did it. They’re not very interesting, I know. I threw them up here as more of a central reference point for me down the road.
