As a bit of info after driving around for years I actually prefer the aluminum oil pans now. I've had so many issues sealing the steel ones with a gasket. They always want to leak somewhere. The aluminum ones just require a small gasket and a gasket sealer all the way around, so much easier. Also it would make your header problems go away as stated above. I've purchased 2 from the dealership now.

As for the length, it sounds like you got a '97-'01 header, instead. The '92-'96 Prelude header is the same length as the CB header. Getting the '92-'96 Prelude VTEC header is akin to buying a header made for a CB with an H22. Maybe that's another casualty of the cheap manufacturing. Who knows?

Originally posted by SSMAccord View PostThe issue that I encountered with my Euro R swap was interference between the header downpipe and the oil pan. The Euro R uses a stamped steel Accord oil pan and uniquely shaped downpipe to clear the oil pan. I swapped to a cast prelude oil pan to alleviate the issue.

Also, just so I know for the future..the oil pan you used was the '97-'01 Prelude?

The crossmember/stiffener isn't an issue with the either stock downpipe. Certain headers require notching the forward crossmember as you already know.
The 97-01 Prelude has the cast oil pan, where as the 93-96 Prelude models have a stamped oil pan like the Euro-R. The cast pan does have a bolted on stiffener/clutch cover that I haven't found a way to install without having interference with the Accord support brace. But the oil pan fits perfectly fine without it.
The main benefit of using the Prelude oil pan is the shape of the sump; it is angled differently from the Euro-R pan and provides clearance for the Prelude downpipe. You can see how the angles are different in the oil pan images.

I have not made any updates on my swap because I have been busy but, the Euro is up & running great!
Finally got Hondata on Friday & hooked it up on Sunday. I used a calibration that I found on the Hondata forum & it works really well. I have not done much but cruised around my neighborhood but this thing sounds awesome.
I might get my Dad to ride with me to do a little street tune. No hard pulls or anything, just to try to get a nice partial throttle drive.
I do have that "whine" noise from the timing belt but, oh well. I read about a bunch of people on the preludeonline.com forum having the same issue after doing the manual tensioner conversion.
So, now all I have to do is get it to a dyno & tuned. There is a performance shop not too far from me call JE Import Performance Inc. who tune with Hondata that I will probably go to. I have a week off in December so I think I may schedule a session during that week.
Oh yeah, does it make a difference when tuning in warmer weather vs tuning during colder weather? Since I live on the East Coast the weather is starting to get chilly (48 Degrees as a high today).Keep Pushing..

Engine is looking great! Glad you've got it up and running.
Yes, there is a difference between a cold weather and warm weather tune. The cooler air is more dense and will cause AFRs to fluctuate in comparison to a warmer environment. Your elevation should be pretty close to zero over in Maryland, though.My Members' Ride Thread - It's a marathon build, not a sprint. But keep me honest on the update frequency!

Did that ECU come with the Hondata pre-installed? Man I like the ABS delete too, I already have parts I saved from my old sedan but I'm not looking to delete the system unless it fails first.

Update from this past week. I was tired of looking at my
ugly header that I attempted to paint black which then ended
up pealing off. So, I bought some Black colored DEI exhaust wrap from
Advanced Auto to wrap the header & the downpipe.
Also, I think that the notched part of the front cross member I did
was not made far enough. At really low RPMs when I let out
the clutch from a stop in first gear I believe I could hear the downpipe
right below the flange vibrating enough to hit the cross member.
If I revved the engine a little bit to leave from a stop it would not
make the noise. It only makes the noise letting out the clutch at lower
RPMS. It sounds like a knocking noise. Almost like a loose suspension piece.
It is just weird because it sounds like it is coming from
the very front of the car. I retightened up the tranny mount to be safe as well.
I have never replaced the bushings for my front lower control arms so,
maybe since I have those stiff Innovative Mounts it could be stressing on
those worn bushings. Hm..might have to jack up the front tires again to see
if there is some play in the tires indicating something in the suspension.
I did not check the front mount yet to see if maybe it needs to be tightened
again. I just hope it is not a clutch or first gear issue! Other than that
the Euro-R is running great.
Anyway here is the header wrap job:
