Twin Turbo EG33 Build - cozykat
This a thread where I can try to document my build with information, images (stored on photobucket), and cost.
The plan: rebuild eg33 - lowering compression to 9:1 and going with forged internals, run standalone ecu (hydra), add twin turbos (something like two T2560), and update exhaust. ----------------------------------------------------- Initially, I was rebuilding my engine because I thought the engine was experiencing rod bearing failure. Once we started taking my engine apart, Shaun noticed that my flex plate had a thin V-shaped crack in the center (noticeable when directly pushing on it). So we think this is most likely the reason for the horrible noise @ 4000rpm instead of bearing failure. 4 reasons I decided to continue with the rebuild: 1. my engine was already out on a stand 2. we weren't 100% sure that the flex plate was problem or just a coincidence and I didn't want to swap engines again only to immediately need to swap for a 3rd time. 3. Shaun's '92, 90k engine runs significantly better than my '93 150k engine in my car which told me my car could run better even with a simple rebuild. 4. the excitement of the rebuild had already got a hold of me. ----------------------------------------------------- Engine Rebuild Projected Costs (your prices may vary): ----------------------------------------------------- Swapping engines (~$230 - Fluids, Gaskets, hoses, clamps) Subaru Gasket Kit ($250.00) Eagle-H Rods ($465.00) Crankshaft ACL Bearings ($200.00) CP 9:1 Forged Pistons w/ pins and rings ($948.00 / $1896 for Shaun and I together) ARP Studs (long/short) ($320.00) Outlaw Phenolic Spacers ($115.00) GrimSpeed Ported Exhaust ($280.00) Cometic Head Gasket Set ($190.00) Hydra + wideband (optional) (~$TBA) STI injector set (550cc) ($360) Cams (~$600) - still to do Walbro Fuel Pump 255lph ($84) Custom Exhaust (~$TBA) Machine work: Total w/ misc parts ($870) Stock Crank - Polish/Balance (~$70.00) Stock EG33 Block - Bore to 98mm ($140.00) Heads - Resurfaced/Check Align Bore ($170.00) Intake/Exhaust Valve Seals (~$105.60) Valve Job($150)/Replace Valve Guides($50) Balance Engine (with pistons, rods, crank) ($150.00) ----------------------------------------------------- Current Status: ----------------------------------------------------- 2009.01.17.SA/SU: So far, Shaun (YourConfused), Matt and I have removed my engine and swapped in Shaun's spare from his 92 (so I can still drive my SVX while her heart is being worked on). Swap cost: ~$230 to replace fluids, hoses that broke due to age, etc. 2009.03.14.SA: We've have torn the engine down and are waiting for a slot to open up at the machine shop (3 week waiting period). Cost: blood, sweat, and cursing 2009.10.09: Got my block back from Duffin Engine Service machine shop. yay! Looks great, except the block isn't as clean as I wanted it so I'm taking it to get soda blasted when I get some free time and $. lots of time passed... 2014.2.18.TU: I'm back at it.. Picked up STeeL25T's Hydra, cleaned up long block, hard lines, and coated with motor paint (fuel resistant,etc) Cleaned and assembly restarted long block assembly complete more to follow...

Re: Twin Turbo EG33 Build - cozykat
Why not go to something a little more boost friendly like an 8 or 8.5 tops?

Re: Twin Turbo EG33 Build - cozykat
All sounds very good to me, right down to your turbo choice. You're going a similar route to me. I'm doing the same thing except with m24 garrett turbos and my own engine management with an svx maf stuck on the inlet of each turbo and an hks or hks knock off foam filter on each maf. Water injection, no intercooler.

Re: Twin Turbo EG33 Build - cozykat
With compression numbers and turbo sizes like that, I'm guessing you're aiming more at a nice driveable torque curve than crazy peak power numbers?

I am considering meth injection but am holding off that decision until I am actually in the process of the turbo. Will you also be installing a tank that includes a level sensor, or installing a water pressure gauge? Yup, I don't plan on ever making this a track/race car just use as daily driver. My goal is to hit maybe 300whp if I make a little +/-, I don't mind.

Re: Twin Turbo EG33 Build - cozykat
i'm driving around on 8.5 compression na right now. It's not so bad. You can feel comfortable going that low if you want. It will certainly give you more cushion to not need charge cooling as much.

With your standalone, you'll be able to ramp up ignition timing for low RPM/off boost driving with the low compression, which mostly makes up for it. |

This compression what what I will choose on my EZ30R going in my Impreza when I turbo it later down the road for the same reason. Though I have my mind set on a single GT40R twinscroll with a light hot side to spool somewhere in the 4-4.5Krpm range to have it when I want but not have to boost all day. I'd love to twin turbo a second SVX if I got one as I'd like to leave this one as an NA build so I'll be eager to see how you route things and what does/doesnt' work. GOOD LUCK! -Gaddis

Re: Twin Turbo EG33 Build - cozykat
Wow, nm. Small-car's are $30 a piece which makes them $60 a pair( I thought they were twice as much). I am asking $100 a pair for mine. As long as small-car still has them. (I know they didn't want to stock them for a little while) I would recomend you buy their's

Re: Twin Turbo EG33 Build - cozykat
So, I ran the SVX at San Antonio Raceway with Shaun's stock block (~92k) and my stock tranny (~80k). I thought it would be a nice comparison for later.
My best time was 15.7s @ 87mph and I weighed in at 3660lbs (with me in the car). Weather conditions (3/25/06) while at the track (Zip:78257): --Time--------Condition/Felt Like-----Dew Pt--Humidity--Visibility-------Pressure--------------Wind--------- 6:05 PM - Mostly Cloudy 81°F / 82°F --- 62°F --- 52% -- 10.0 miles - 29.71inches (steady) - From SW/3mph 7:05 PM - Mostly Cloudy 81°F / 82°F --- 62°F --- 52% -- 10.0 miles - 29.72inches (up) ----- From ESE/6mph 8:05 PM - Mostly Cloudy 76°F / 76°F --- 60°F --- 58% -- 10.0 miles - 29.72inches (steady) - From NE/14mph 9:05 PM - Partly Cloudy 66°F / 66°F ---- 53°F --- 63% -- 10.0 miles - 29.75inches (up) ----- From NNE/8mph 10:05 PM - Partly Cloudy 63°F / 63°F --- 53°F --- 70% -- 10.0 miles - 29.78inches (up) ----- From E/9mph
