Default Anyone interested in this? Phase1 - Phase2 adaptor

I made a set of adapter plates so that I could bolt a Phase 2 (offset intake) long block under a Phase 1 (inline) intake manifold. The idea is that you could bolt up the engine without having to change any sensors/wiring/anything. Just bolt it in and go. I had some trouble sourcing a 96-99 EJ25 for an outback at my shop with a blown engine. All the local wreckers had the Phase 2 SOHC engines though, so I built the adaptor to make it work.

Just wondering if anyone is interested in these things. I could make more if needed. It could make engine/head swaps a lot easier.

I have to ask a new question to this whole project. I currently have both a DOHC and SOHC manifold hanging side by side in the garage and the SOHC manifold seems to be quite a bit longer (wider as mounted on the motor) than the DOHC. Has anyone measured the span across the motor from port to port? We know from overlaying gaskets that the bore spacing is the same and the general port shapes are close.....but it looks to me like the placement of the ports in relation to the centerline of the crank may be quite different.

SOHC:
(0 0)

-----]

(0 0)

DOHC:
(0 0)
-----]
(0 0)


Any thoughts?
Jay

Well, you're the one with the two intakes, Jay - measure 'em!! I'm curious to see what you find.

sammydafish, I might be interested in a set depending on what Jay finds when he measures the manifolds. The intake manifold on the '05 cars is supposed to be the shizznit, but it's got the SOHC bolt pattern so it's a no-go on my DOHC motor. If I could make it work with adapter plates, though, I just might try to do that.

It would be cool if you made these to put 2.2 manifolds on 2.5s.

They should already fit. I have a 2.0 intake (EJ20G) and a 2.5 intake (EJ25D) sitting in my garage and they're interchangeable.

EJ22 and EJ25 manifolds don't swap. the bolt patern is the same shape, but the EJ25 is larger. Have you actualy tried to swap that manifold on?

The engine will go in the car within the next few days and I'll post up the results. I'm pretty sure they are the same length. I have both manifolds off the engines, I'll match them up tomorow. The phase II engine that's going in is blocked up by a bunch of crap right now, so I won't be able to actualy bolt the whole thing up for a day or two. It sucks having a small shop.

When I posted, the manifolds were 1/2 hr away from me and they still are. I'll make it a point to get over to the garage (reach all the way up into the rafters) and measure them......

EJ20G and EJ25D are virtually identical heads. Accessory mounting's a bit different but the manifold mounting is the same.

EJ22E and EJ25D, 251 or 253 are different animals altogether.

I'll post what I find out. I hope those prototypes didn't take too long to make.

Well, I stand corrected. I assumed since the 2.0L and 2.5L manifolds were interchangeable that the 2.2L manifold would be, too (assuming it has the correct bolt pattern, of course).

Okay, I got over to measure the manifolds once and for all. The news isn't good for this idea. Here's what I came up with (mm):

From runner floor to floor (inside edge):
DOHC= 478
SOHC= 490

Center to center:
DOHC= 501
SOHC= 515

Inside ridge of injector boss:
DOHC= 535
SOHC= 562
(this could be a matter of port shapes, which are also different)

Finally, I couldn't get an accurate measurement of the offset of bores because frankly I didn't take the time to jig up a centerline on the longitudinal and horizontal axis of the plenums. They are different though as well. Simply put, if you lined up one side with the adapter plate, the other side would be off in both directions....side to side and front to back.

I wish I wouldv'e done this months ago when I first hung them bastards up.....

I got the motor out and set it up. the SOHC manifold is a little longer. I think I might be able to make it work though. I'll post what I figure out soon.

Probably with a thicker plate, an angled approach could be made to extend the curve of the ports and keep everything hunky-dory.

One would have to ask WHY you need a set. There very well may be a better solution.

I have a WRC phase 1 manifold that I'd like to run on v7 heads. This would make it easier that's all.

ahh, gotcha. I think you'll have to have some machining done. [shrug]

If you dont decide to use the wrc manifold let me know.

Pretty slick, but the whole "You must cut your manifold in half and extend it" bit puts this out of reach of most folks.
