Default Suba03ru's Bugeye Track and Street Build. Lots o' Pics. Precision, Wiseco, AMS, Etc

Hello to all,


I have been on the forums for about 4yrs now and have mostly used it for the classifieds, but now its time to post a build journal. My last setup prior to this last deployment made apprx 350whp/350tq. I was still running a stock block and a stock location turbo and E85 for fuel. Nothing happened to the motor or car, however the quest for more horsepowers was calling. Upon purchasing the car a few years ago from a single owner my first upgrades were suspension, BC coilovers, Whiteline sways f/r, TiC bushings, mounts, etc.

Stay tuned for updates and photos. Any feedback or input is welcome. I will entertain valid points but I'm not a fan of E-Thuggin, so if you dont have anything nice/constructive/valid to say, dont say anything at all.

Mod List Prior to Teardown(for the most part)

VF43 w/ port work
Fuel rails, lines, walbro intank, w/ 1300cc injectors
Ported Intake manifold, Throttle Body and TGV Deletes
Blitz Nur Spec Exhaust
Bellmouth Downpipe
EWG up pipe w/ TiAl 38mm V-band
DC Sports exhaust manifold
COBB SR intake
Gimmick turbo inlet
Spec stg 2+ Clutch
COBB Accessport with a Tune from Mikey Botti of PhatBotti Tuning.

These are the big things that really made the difference in the car, obviously there are dozens more small things but those are the big ones.


Additions/New Items on the new build:

-Wiseco 99.5mm pistons
-TiC/MAW Composite TGV's(very excited for these)
-Rods are still up in the air......?
-Fluidampr Pulley
-Crower Valve Springs and Ti retainers
-GSC Nitrided valves
-BC 280 cams.....might sell for 272.
-AMS 750R Rotated kit w/ PTE turbo, TiAl 44mm EWG, catless downpipe, v-banded all around
-Ditching the Agency Power fuel rail setup for a custom setup with an Aeromotive FPR and a 2L swirl pot with a Walbro feeding it and then a Bosch 044 feeding the 1300cc injectors.
-P&L AN head breathers to a Crawford AOS
-11mm Oil Pump
-Mishimoto X Line radiator w/ Zerosports Thermostat
-Nitrided Crank

I Haven't decided on cams, rods, or bearings yet. Input is welcomed. The goal for the car is roughly 500whp with high 400's in torque. Fuel will be E85 again and the purpose is to compete in time attack/road racing.

Finally some room to work. Subaru motor bays are so ridiculous. There are hoses, lines and cables everywhere! Cruise control, AC, and a couple other small items will no be going back in.

Correct, it is a valve spring compressor, very handy tool to ave if you do a lot of Subaru head related work.

Yea the motor mounts were very frustrating. They have only been in for a few thousand miles and one of them would only break free from the motor and not the chassis.

375 whp on an STI turbo? Do you have a dyno plot? Just curious as I haven't seen numbers that high with that turbo.

Build looks good though.

What sort of power do you expect to make? Are you running this only on pump gas or on race gas, e85? The rods I have mentioned BC I beams tons of times now. I think they are more than strong enough for this type of setup and won't break the bank. However Manley came out with a new H beam the H-tuff that looks very good for the money too. For bearings pretty much all of them have had success. I've used acl and clevite personally and also used one company for rods and another for mains and they've all worked just fine. That said I'm in the process of building an engine for a customer now that I'm using the King xpg bearings and that's what I picked for my personal car also. I really like the full 360 groove design for better rod oiling. I can't offer any experience with cams except BC 280's which a friend picked up about 40whp on an FP red with over stock cams. Maybe call a couple shops and ask what they think. I know a couple have tested cams. I like the fluidampr and the rest of the build looks fun.

I would like to be around 500whp and mid 400's for torque, howver, I'm not a number chaser as much as a porsche and corvette chaser on the track. So endstate numbers dont matter as much to me as overall performance and useable power. This build will be strictly run on E85 w/ the potential to do a tune on race gas later. I dont know if the 1300cc injectors can be stretched that far, guess it will be up to the tuner. I have been greating results running E85 as has everyone I have talked into running the Jesus Juice. I have heard about the Manley I Beams as well as their new H-Tuff. I think I may go with the H-Tuff, if I can find a little more info on them. King XPG bearings you say? I'll see about ordering some. I like the cost effectiveness of the BC cams, however there are many quality cam makers out there. We'll see on the cams.

I mistakenly wrote 375, i meant to write 350/350. I dont have dyno plot info currently, we had the boost @ 24psi however that wasn't very efficient on the VF43. For the current tune it was dialed in at 22.

Tossing around the idea of pinning or sleeving the block after talking with the engine builder today. Power goals don't necessarily warrant either and the bores are clean and don't need to go bigger but that extra piece of mind is always nice. Any arguments to justify the cost either way?

That's the intent, yes. I plan on getting the combustion chambers machined to match the 2.5 and decked at the machine shop then I will port and assemble.

Spray some PB blaster all over the bolt, hit the bolt with an impact gun for several seconds repeat process and then try a big breaker bar again. Doesn't have to be a strong impact just enough to vibrate. I used a little 12v 1/4" drive last time and it worked. I've also drilled them before I tried that.

lol. I've twisted my snap on 10mm bit before. Those things are on there! I broke a couple loose much more easily the way I mentioned above though. I was pretty surprised. I weight around 185 lbs and I've hung off of my 1/2" breaker bar before trying to get those things off LOL

I think I'm at the carbide bit point. I've snapped three wrenches, two sockets, and I've tried a big breaker bar and I weigh 230 and no joy. I'll try the impact for the good vibes today lol.
