Ez30d swap
Hey, I am starting my Ez30d swap out of a 2002 outback sedan into my 98 forester (I know this is a impreza thread but shouldnt be much different, delete if not allowed) I am not keeping ac and I am thinking about using the holden astra electric P/S pump. The plan is to use the stock ecu. I have the the donor car so that makes things a lot better! Who has done this swap and what did you run into during the swap that you didn't expect? Any general advice on the swap would be pretty cool as well! Just trying to get as much knowledge from as many sources as possible!
Thanks in advance Last edited by yonak44; 05-10-2020 at 06:56 PM. |

Ya, here in MN as long as it drives it can be on the road so as long as the codes aren't critical I should be fine. I heard good things from a friend about that pump that's why I want to try that one out. I plan on doing the exhaust once I get the engine in there and can get exact lengths and angles. The biggest thing I'm worried about is the wiring as I haven't done an engine swap before but I think my wiring knowledge should carry me through the project just hoping there isn't any big surprise moments that are weird to track down. I am planning on mocking up a belt with the current belt so I can get an good measurement and then take that to the parts store to see what they have. |

Thank you! Im doing all of the research I can possibly do while doing this project and am in no rush! I might put a post together as it progresses to keep everyone updated! |

Does anyone have some good photo's of exhaust manifold routing for a single turbo ez30 application? I recently found the raptor headers leave a lot to be desired as far as ground clearance so i'm looking at modifying them or starting over to do something similar to the Perrin build.
I'm also open to other idea's aside from a low mount in front of the engine, id prefer to avoid that. I did some painters tape mock up of mounting the turbo in the area of the ABS pump with the up pipe coming from the front side of the engine, over the passenger side head however short of venting the entire side of the hood I feel that would always have heatsoak issues I also looked at mounting it in the OEM batt location however that is still rather far forward and not preferred Any insight or advice would be greatly appreciated. Thanks -Jacob |

Hey guys,
Can someone here please confirm for me what the diameter of the exhaust port is on the 3-port exhaust ez30's? I've searched this thread and google. I've heard 38mm but am not certain. I am looking to make some simple turbo headers like the might car mods supergramps and have a bunch of 1.5" OD tube lying around. Super gramps used 1.75" but they mentioned it didnt really need to be that big.. I wont be building a 400kw type thing, max I would expect is about 230-250rwkw. Cheers |

Thanks Kito! I'm assuming thats 1.5" OD pipe?
I was looking around last night and found the 32NB (1 1/4") sch10 pipe has an inside diameter of 36.7mm vs 1.5" pipe which is 35mm and is about half the price which is awesome. BUT I still want to confirm the actual exhaust port diameter which I think this is going to be 38mm. If it is thats only about 7% larger in area than the 32NB pipe.. If you could grab a photo of the port with a ruler on it that would be awesome, we can finally confirm the size for everyone in future! |

EDIT: Seems I was wrong and they're 1.4" (~35.5mm)OD with the tubes having a thickness of 1.5mm so the tube ID would be around 32.5mm. Here's the link to the ebay listing for the headers I have, they say they're for the ez36, but they bolt to the ez30r(3 port exhaust) without issue. https://www.ebay.com/itm/163667971250 Again I'll measure when I pick the car up again on Saturday.

I have a set of EZ30R heads in my basement and measured the ports at about 35mm. However, the heads have been ported, and I can't really tell how much material was removed, so that number may be off. It looked to me like most of the port work was done inside the exhaust ports, as opposed to at the openings themselves. I don't think the ports were hogged out much, but I can't be sure.
So I'm curious to see what Kito reports from his. |

The holes in the exhaust gaskets are 1.5 inch. Same with the EJ IIRC.

I've been lurking here for years and I finally started my build in November 2018 by acquiring a 2004 Outback H6 with a blown head gasket and a 1995 Impreza L coupe. The car will be used for SCCA Rallycross. Early in 2020 I did a 2wd->awd and Auto-> Manual swap on the coupe. I tore the entire H6 down and had the cylinders honed, the block/heads decked and the valve seats re-cut. The motor is back together now and in the original donor for break-in which I hope to do in the next few weeks.
I will be using Megasquirt III with expansion board for tuning. It looks like they now have support for the motor in a beta version of the firmware. The question I have is this: Has anyone done any tuning on the induction valve? For those not using the OEM ECU, do you see lower than expected performance in the 3k-5k range? Has anyone just used a different intake manifold? I was unaware the induction valve even existed until I tore the motor down. I have been able to find very little information on it at all. It is a flapper type valve that sits in the intake manifold and from what I read diverts air to improve torque at different rpms. What I've found so far: https://thefactoryfiveforum.com/arch...p/t-20434.html https://downtime.nasioc.com/forums/s...748385&page=41 |

I've now got an n/a impreza 2.0 my ecu gave up in my legacy. I've still got the ez30d engine and would fit it into my impreza which is easy . It's just management I need now . I've nearly fabricated turbo headers for it to

I'm not sure why not using the OEM ECU would cause lower than expected performance from 3k to 5k. It is possible to put the '05+ 30R plastic intake manifold in place of the 30D's aluminum intake manifold, but it's not a straight swap, and I don't know that I've seen anyone actually do it. That's something I intend to try at some point - but again, first I need to get the car running. Quote:

Thanks for the clarification on behavior.
It sounds like maybe the thing to do is to somehow log what happens with the OEM ECU, at least the signal to the valve solenoid and then do something similar while tuning. I have a tactrix but haven't really used it. I've been looking the last couple days and can't find a definition for the H6. I'll continue that on the back burner. I'm going to break-in the motor and try to get the MS working with a base map and get fuel right. I will probably then take it to someone that knows what they're doing to get the timing tune right. If I stick with it, I'll post back what I find. |

If you haven't already found it, there's a FB group called Six Swapped Subarus that has some decent information. I would say it's a bit more EG33 stuff than EZ30, but there is EZ discussion, so you may be able to find help for the MS tuning.

I got impatient and pulled the exhaust manifold off my ez30, far enough to see the ports. I. 99.9% certain they measure 35mm. I couldn't get the ruler right up on the face but close enough to see that it wasn't 38mm.
The rings on the gasket measure 44mm. Edit: Here's the pictures, 35mm and the headers reduce to about 30mm just after the flange. Edit 2: I ordered a head bolt to measure for myself due to the million different reports on what thread they are. Here it is: M10.5x1.25 pitch, 136mm long. Same pitch as a bellhousing bolt. Now to find some reasonably priced studs! Last edited by nvmylh; 06-22-2020 at 08:33 AM. |

Yes the OEM headers and cats are massive choke points. The raptor headers make a massive difference (if paired with a proper exhaust obviously).
I put an my16 sti catback on my legacy and that alone made a huge difference. In short, the OEM exhaust is woeful. |
