I was just gonna run the D ones till I got around to using machining stuff or CAD and made some solid ones... See if I could manage clearances to get 1/4" lower with the motor. Twin scroll means I'll have two smaller diameter sections of exhast to run through the GDB xmembers notch.

ok so my state transport authority says the only thing that will stop my swap getting registered will be the emissions. anyone have any information RE: emissions of these engines?
i mean i don't foresee any problems so long as there's a cat in the exhaust but better safe than sorry. |

Plug in. If you don't pass ODB2 readieness nothing will be worth anything.

No it's on my vast forgetting that not everyone is in the US. It's still a most likely case if there is any emissions testing I would presume.
It is a wonder if those other market ECU's that are opensourcable will let you force readiness like the US WRX and STi ECU's. |

Generally you want the cats closer to the head so they warm up and become effective more quickly.
With that said, the 2" ones are pretty tiny, so I may change my mind at some point. We'll see... |

and to make my third post in a row: anyone looked into forged internals for these engines?
there's a couple of brands that make production/off the shelf rods and pistons, BUT... i'd really like to run a custom job with them. like the MPS engines, i'd love to get a custom piston made with the wrist pin further up the body and longer rods to compensate. i haven't contacted any manufacturers yet but i've taken a squiz at the piston.. i can't help but think that short of machining into the bottom ringland (which has already been done stock) there isn't much room to move. aftermarket manufacturers are already doing this as they increase the total thickness of the ringlands on their forged pistons. supertech: mahle: |

I hydrolocked the EJ25D in my car last week, so it will sit until the EZ30D is in it. No point in fixing the EJ25 or finding another one to throw in there when I have a project that I've been meaning to do for so long!
I had to give the heads back to the machine shop for some clean up on the lifter bores - previous machine shop nicked the bores when they tore the heads down to clean up , so the lifters didn't want to slide in cleanly. Should have the heads back this week, and perhaps this weekend I can actually work on assembling the engine. I'll also be working on pulling the EJ25, once I get my other car out of the garage (currently taking it apart for some header test fitting). I've exchanged emails with Franz Diebold @ Diebold Autosport about doing the Vipec V88 install. He's a few hours away in Winchester, VA, which is coincidentally where I picked up this EZ30D back in December. He's awaiting word from me once I get closer to actually bringing him the car. |

I came here to say I want a 3L H6 that makes 100hp/L naturally aspirated and want you guys to figure it out, then swap it in my vehicle. Thanks. God bless.

EZ30R is probably the most accessible/easiest to swap over. EZ36 is the engine i'd swap if i could/was going to stay NA, but it'll cost you $thousands more. reliability with an exhaust & tune? same as factory. in fact possibly greater. all alloy engine, about 35kg heavier than an ej25. |

EZ30D is easiest in my book, with a close second to the EG33 the cheapest. If you are putting in the work the EZ36R should be only slightly harder than the EZ30R.
100hp/L NA? I'd do an EG33. Stock they are way under powered compared to what can be extracted. Vicious, why do you want to shift the geometry of the pistons and rods? |

You want to rev the piss out if it? Valve train, porting, and oiling.

Now I'm seeming to remember an earlier conversation about the Subaru engines other than the FA not mating to the bell-housing of my Aisin trans. Quote:
"Output: 256 hp @ 6,000 rpm, 247 lb-ft @ 4,400 rpm" Must rev higher and needs 100 more hp...these stock numbers are about the wheel output of a very well tuned up twin-screw supercharger with supporting modifications. |

but my older EZ30D without the oil draining AVCS is much more racetrack/rpm friendly. Quote:
yes that's the ez36. getting one and getting it swapped on the other hand is fairly difficult. Last edited by vicious_fishes; 08-01-2013 at 07:15 PM. |

I'm thinking about swapping an 02 EZ30D into an 02 OBS. If I get a donor car, do I just need to swap the bulkhead to ecu wiring?
