Default Frankenstein EJ257 block with EJ25d 4 cam heads, Turboed, INSANE!

So.... this is not my first build (thats here: http://forums.nasioc.com/forums/show....php?t=2003843) and it is not my first hybrid build but it is my most effective yet. This is an ej257 short block with EJ25D 4 cam heads and many many other mods. I will be posting pics and stats...etc etc in the next few weeks but I will say this is ridiculous! I spin all four tires through first and second :-) Never thought I would see such results!

















1 2008 EJ257 STI short block (rebuilt from three bad ones)

1 1999 Set of Legacy EJ25D 4 cam NA heads (Love the solid lifters, and composite gears)

1 JDM B4 Turbo Legacy Intake Manifold

2 1999 Factory Fuel Rail Return Sides (Tee off the supply and return to
these, try to keep equal lengths)

2 2002 WRX Fuel Pressure Regulators (Keep the vacuum tubes as short as possible, it helps response of the fuel lines)

4 2004 STI Fuel Injectors

1 Walbro 255 Fuel Pump

1 1992 Turbo Legacy Crossmember

1 2004 STI Water Pump

1 2004 STI VF39 Stock (not rebuilt) Turbo

4 2004 STI Stock NGK Iridium Spark Plugs

1 2002 WRX Ebay Header/Up Pipe (welded in EGT bung and welded shut adjustment)

1 Perrin Lightened Crank Pully and Flywheel

1 ACT 6 Puck WRX Sprung Clutch

1 Clutchmaster WRX Pressure plate (i think stage 3)

1 2001 RS Transmission, JDM LSD rear Differential, WRX Shifter, and cable clutch (Can’t adjust hydraulic and better workout)

1 Custom 3.5” Turboback Stainless Exhaust W/Blitz Nurspec Muffler (you could almost climb inside)

1 ???? 7lb WRX factory wastegate

1 Greddy Emanage Blue (Formerly Apexi Sitc And Safc but needed more control)

1 Greddy Profec E01 Boost Controller

1 Set of NGK 8mm custom plug wires and soon to add MSD ignition coil (temporarily 97 impreza coil adapted to work on 95)

3 Apex ELII System Meters/Controller (Fuel Pressure, Boost, Pyrometer)

2 AEM Guages (Wide Band O2, Voltage) Voltmeter because I moved battery to the trunk

1 Ebay Knock Meter and Factory Sensor (Stopped working caused me to blow an engine, stole my friends meter for now)

1 Generic Ground harness Kit for the engine to the body

1 Redtop Gel Cell Battery and 4 Gauge cables (Little heavier but more reliable power and no corrosion in my trunk)

1 JDM WRX Large radiator, high pressure cap, and Jeggs custom in hose radiator cap adapter

1 JDM STI Carbon Fiber Front Strut Bar

1 97 impreza wagon dull pump washer bottle used as intercooler sprayer

1 Cusco Aluminum Rear Strut Bar

4 Ebay fully adjustable rear lateral links (kind of heavy)

4 2002 WRX Brake caliper and rotors front and back (should’ve used steel braided hose)

4 Dunlop Direzza Z1 Sport tires (Good tires, Great grip, Strong Side Walls, Awesome Price)

4 2002 Wrx Rims previously legacy gt rims (have a set of 2011 BBS STI rims but they are different offset)

1 JDM Nardi Steering Wheel

1 Ebay Turbo Blanket (works great)

1 1995 oil pan with turbo return line welded to it and oil feed steel braided hose/connector from engine

2 Rear Ladder braces (Not yet installed)

Lots and Lots and Lots of various Hoses and fittings!!!!!

1 Fire extinguisher (for when it all goes BOOM, and it will because you can’t know your limits until you’ve exceeded them, I just hope I get it on video)

Infinite help from my friends especially my friend Alan, he opened his own shop and taught me how to rebuild a block from scratch (literally). If you live in the orlando area and want a very good Subaru mechanic and for cheap Call 407-982-0888 and ask for Alan.

Currently running 15lbs of boost on pump gas, when the STI intercooler and MSD coils are in I will turn it up to 18-20lbs. I will be taking it to the 1/8th mile track tomorrow but dont worry I will granny shift so as not to leave my tranny on the track. I will also be dynoing it as soon as the sti intercooler etc are in. So far this is the fastest build I have ever built, and the fastest Subaru that I am aware of in olando (atleast 1st through 4th gear, after that I am in overdrive and it is too much strain on the engine for my likeing), I easily took a Z06 Corvette the other day and as long as I feather the gas allowing the tires to hook up Im sure I will continue to upset alot more people lol. There is one big problem with this build, it tries to kill you in a turn :-) I built a high compression forced induction, large piston engine with ALL lightened pullies, gears, flywheel....etc (like a circuit race car kinda, I am more concerned with response than top end power), and it is tuned as such as that until boost kicks in timing is advanced and fuel is 14.7:1 A/F but when boost kicks in it starts at 12:1 A/F and works its way to 10:1 A/F at the very last moment as well as I set the emanage to dump fuel inbetween shifts and at no throttle high RPM moments (TERRIBLE gas mileage), this effectively cools the egt's down two fold. All that combined with the aggressive N/A cams this is the most throttle happy car ever with no knock (except in 5th gear like normal). My only concerns are the heads because they are used and interference so I am afraid it will surrender eventually but they are also the special ingredent in this build and I am taking the risk for the rest of you. Ill keep you all posted as often as I can. I am assuming the HP will be in the 300's, just hope i dont start breaking stuff too soon. Everyone keep there fingers crossed for me.

Default 1/8th mile results!

Zoom in on the photo I added a dialogue explaining the track tickets.

Thanks guys for the kind words. All in all it went good at the 1/8 mile but the hodge podge ignition coil I am temporarily using let me down, and yet surprisingly I was still slipping tires on that sticky track lol! I will go back to the track when I have changed the coil, intercooler, and dynoed it. My current challenge is how the "F" do I bypass the redline. Its set to 6000 and this build can easily do 7500. Any ideas? Im gonna start by bypassing main relays, and fuel relays etc.

New Intercooler and oil breather replumbed! Barely fits! 2008 STI intercooler.

Should have my MSD ignition coil installed this week. So glad not to have oil going in to my turbo anymore and turned up the boost to 20 psi now. If all goes well should dyno the car this week.

What is the hose running out of the oil cap? how do you have your valve cover breathers/pcv set up? Nice build!

On the sti block it has an extra breather that is supposed to be fed to returns on the heads but originally I just tied all the breathers together and then to the PVC valve and then intake like on a NA car but that won't work on here cause there is so much oil spray coming out of that extra breather that it was filling up my intake box like a catch can. I saw a after market breather kit for our oil filler cap and so I realized I could use that as a return and it has worked perfectly!

Thanks I will try my best to video the dyno and maybe a pull or two around town. My msd coil should be here tomorrow, as long as there's no rain it should get installed and tuned in time.

Why did you replace the stock coil with the MSD one?

Because the stock coil did not burn the fuel properly causing missfire, rich mixtures, and less power.

Car weighed in at 2654lbs


The dyno proved both better and worse than what I expected. After reviewing the power curve and monitoing my guages during the pulls the staff at PRS showed me where there is a lot of untapped power. But for now the car is putting down 243hp (less than I thought) BUT it put down 312ftlbs of torque (better than I thought) this explains why I can spin all four tires with four grown men in the car. I will be tuning more and perfecting the fuel, boost, and timing curve to bring it back for my 300hp I deserve

Love this thread, it gave me a new thought, at first I really wanted to do an ej207 swap and with my present financial situation i can't do that so I am doing an ej25d swap now into my coupe, and later I should be doing something quite similar to this.

The next dyno run you should do a side by side with the original coil. I would worry that the dwell time on that replacement coil might mess with timing slightly

I picked the ej25d because of the solid littered and huge valves plus it is high compression so the throttle response is unreal. unfortunately I just had a string of bad luck and I have to either park it for a bit or put my ej18t back in. I run a dual fpr setup and its great until something goes wrong. I had developed a pin hole in one of the vaccuum lines of the regulators and I was in the midst of tuning so I didn't notice the issue till my egts got so hot that it cracked two pistons. Normally I catch this sort of thing but the other part of this string of bad luck is that my Egt probe went bad days before ugh. So now I have to check prices and see what avenue is the cheapest. I have been unemployed for a while now and can't afford to buy much. Besides there is soooooo much potential in that build I think I need ti take it all back apart and build it with new parts from the ground up (when I get a job of course lol) but the ej18t I already have sitting here. I got 215hp out of the ej18t but no where close to the torque of the ej257. It would be nice to be light weight in the front again.

Great build! If you can break all 4 loose in 2nd gear with 312ftlbs it might be time for new tires.

In for 1/4mile times! And corvette killing videos!

Unfortunately things went south with this engine. It is not ruined but I need $ to build it right so I stuck the ej18t back in for now. I am running two fpr parallel and one went bad (slightly) during tuning and I was unaware because my egt guage also went at the same time so basically I tuned it with one side rich, one side lean but my wide and was readi g somewhere in between and I would've caught the problem if my egt guage was working but it wasn't so I cracked two pistons right when I realized it. I am going to use this motor in a bigger car probably an svx because it is totally overkill for a car that weighs 2400lbs. I would have to put huge rims and tires on which means wide body...etc just not worth it. I really shouldn't be building anything till i finish school anyways cause I have no money so I have to use parts i already have which means used parts but I just can't let it be. I am still a firm believer that an ej257 with ej25D heads and lots of boost is the supreme setup for throttle response and torque but its a bigger build than I can budget right now. I'll update the progress of the ej18t build but i won't be as exciting especially since I'm going for quiet and stable. My 3.5" Turbo back is getting me too many tickets :-\ as for the videos I don't have any. Honestly its not hard to picture this as reality because I have a very low gear ratio in comparison to the vette. I only was faster till about 85-90mph and then he had me. I was in 5th by this point he was probably just leaving second gear so I only had better acceleration but the vette is faster in the end.
