I figured I would make a thread, I have an 05 WRX and looking to go stage 3 soon. Here's how car looked 2 years ago:


Now:


And I learn to wrench on this car as I go. I'm a sloppy mechanic.

Things that have been done to the car
- TD04 19psi, Self Tuned
- GM EBCS
- TGV Delete
- Walbro 255
- Perrin Crank Pulley
- APS 65mm CAI
- Catless Invidia Uppipe
- Catless Helix 3" Downpipe
- A'PEXi N1 Catback
- Kartboy Shifter Bushing
- Perrin Rear Diff Bushings
- Kartboy Outrigger Bushings
- Group N Engine/Pitch Stopper/Trans Mounts
- 2005 STI Springs
- RallySport Mudflaps

Recently:
- VF48
- '11 WRX 565cc injectors
- 20psi tune (283whp/297wtq): http://forums.nasioc.com/forums/show....php?t=2484001
- '04 STi struts with JDM Sti pink springs
- Rota SVN 18x8.5 e48 5x100, Nitto NT05 245/40/18
- STi catback hah

I don't happen to have pictures when I did the TGV delete, but while I was there I painted the intake manifold red:


At some point I bought '01 RS 6-spoke wheels from a friend (only for $200) and installed mudflaps:


Lamco boost gauge and all-weather floor mats:


Last summer I found a good local deal on STi TMIC, got it for $200:

Before I go stage 3 I might need to hit up on the maintenance, car currently has close to 80k mi, timing belt hasn't been changed, stock clutch, upon installing Invidia uppipe I snapped a picture of leaking valve covers:


Some other issue that remains unfixed is cracked engine cover, which currently sits ducktaped, since to fix this you need to take camshaft sprockets off, and taking those bolts off of them is a b*tch, but I will attempt it anyway when timing belt change comes around:


Other silly things that happened to me was a cracked windshield, busted tie-rod, busted ball-joint, busted end-link, leaking radiator, battery acid corrosion, cracked uppipe flange, rusted out-hole in catback. I still need to fix 2 front axles, they're both spewing grease all over from inner CV joints.


Baking soda cleaned most of the acid, but rest is corrosion and rust:


Repaired catback chilling there, and ROTAS! waiting till it gets warmer, all this time I had 16" wheels:


My current tuning setup :P

Vf48 waiting to go on, I found turbo locally from '08 STi 38k mi and got it for $345, injectors I bought here for $100, sweet:


Today I installed '11 WRX 565cc injectors (02/23/13):


Currently using these latencies from '11 WRX map
[Table2D]
6.5 9.0 11.5 14.0 16.5
3.15 1.71 1.12 0.81 0.67

And scalar
[Table2D]
Injector Flow Constant
550.67

Prior to the installation I reflashed ECU 7 times and got OL AFRs pretty much 11 flat. APS 65mm seems to flow nonuniformly for me starting around 3MAFv:
(x-axis: MAFv, y-axis: g/s)


With new injectors I'm running rich, the fuel trims in range A 0-5.6g/s are -6.5% after off-boost cruising. I will try to reduce latencies by 0.06m/s and try again.

Pulled the td04 off today (02/28/13), I never took off turbo before, went pretty smooth:



Still need to put vf48 in, and start tuning boost, timing and fuel should already be good with my current tune.

Vf48 is in. Here I could not for the love of god screw back in the bonjo bolt, bending oil hardline and getting right angle is the key:


Here I had to trim turbo elbow coupler since vf48 sits further into the car than td04 did:


Here I bypassed electronic bcs and ran a line from compressor outlet to wastegate, giving me wg pressure/7psi for a safe first drive after install:


At first coolant started leaking bad and oil too, I didn't torque the top oil feed line hard enough. I have first results, in this map target boost was 15psi through whole rpm spectrum, OL is 10.94afr, I have an airboy dyno and a 3rd gear log:

About 275whp/260wtq mustang dyno numbers? Also used STi catback here, with A'PEXi N1 it should be even better:


Not quite 11afr, afrs spiked up to 11.4afr, that's too lean for summer--but it's because of injectors still needing right cc/min value (edit: actually it was the MAF scaling again that needed to be fine tuned):


Learning view after all was said and done:


Looks like injectors are flowing less than 548cc/min (Romraider value), I'm about 0.35afr lean, MAFv above 4.3 is untuned, since td04 never got up there, nice to see vf48 flowing up to 17.2psi at 6.5k rpm no problem, but I'm running very rich up there, up to 0.8afr (10.94-10.5 + 0.35) from what it looks like. I should be easily able to squeeze out another 20/30wtq of torque in midrange. I'm shooting to peak around 20psi.

In next map revision I plan on running more timing at +5k rpm, more boost in midrange, lean out +4.3MAFv, tweak injector scalar, this run used 548cc/min, I will try 541cc/min this time (edit: 546cc/min seems to be a sweet spot), latencies are all good--got that out of the way quick.

Vf48 sounds pretty good, it's giving out quiet jet engine sound when it starts spooling
Once I get everything dialed in, I will hit P&L dyno!

Glad someone else is using RS wheels! I was wondering what they would look like in gold. Mine are duplicolor graphite!

I wasn't specific, I wirebrushed off the rust and dirt, used Duplicolor Rust Fix spray can, it turned any leftover rust into black primer, and then I used another primer in a spray can that matches paint under the hood. Good enough for me.

So earlier today I tried replacing the valve cover gasket including half-moon cam seals:


I applied the RTV paste where manual calls:


However after letting it cure and about 20 miles of driving, I found oil leaking onto exhaust manifold shield, it seems to be coming from the bottom of the cover. I applied more torque to the bottom bolts, but I'm not sure if that will be enough, spec calls only for 4.7lb/ft, or perhaps I already fubared the threads, but I've been careful not to, we'll see if it still leaks.

I found '04 STi struts with JDM STi pink springs locally, the ones that provide lower ride:


Front:


Back:


Ride is much stiffer and lower compared to the WRX struts with '05 STi springs (224/195 lbs/inch). These springs are 257/217 lbs/inch. I'm getting the infamous rear STi clunk, looks like rear struts will need to be taken apart and regreased.

Calipers have been painted copper, actually they have been like that since summer, earlier pics show car before that. Wheels are 18x8.5 Rota SVN with custom wheel caps, I love these, the tires are 245/40/18, I think these are the meatiest that will fit my year, there's barely any clearance left between the tire and the rear struts. Looks so much better than little 16s and 205s.

that much rtv isnt necessary on the valve cover gaskets. the half moon cam gaskets are really the only places that need it. nice build though!

today:


Next thing that I might do are 850cc decapped WRX injectors and e85. More torque would be nice.

nice to see people doing things for theirselves. keep it up.


a 2.5 block would provide you with some more torque
