Default Stuck with sidewider manifold and EFR turbo

Hello

I'm trying to fit in my Honda ep3 a 7670 EFR IWG single scrool turbo with a BWR manifold.
Seems near impossible because lack of space thanks to direction
I think the EFR series with IWG is bigger than Garrett turbo, right?

Question :
is someone succeed with this kind of manifold and Fer IWG?
is full race manifold EFR really different and allow more space to fit the down pipe?

Any. advice really welcome

We cut the down pipe (A full race) and give a try with a mockup
Clearly it is not possible do fix the bend. It touches the direction.

Any advice? I'm probably not the only person trying to fit a BW IWG in a ep3??

My question is

Is anybody can confirm this manifold is 100% accurate for an ep3?

sure it will fit, but you'll also need the full-race dp.
here's someone who fitted the kit on an ep3:

from your pics it seems that there is enough room for some piecut bends. gl

I fit a twin scroll 8374 full race kit in my ep3 so I know it's possible. Your not incorrect though- it just barely fits. I'm not sure how different the manifolds are- I imagine the fullrace one is more model specific than the more generic kswap BWR one. Even with the fullrace kit: I had to do some modification to the steering rack connections and brackets to get the down pipe to fit behind the turbo. It is VERY tight... heat shielding will be your best friend

TY for your reply. Really appreciate.

If I compare the position of your turbo and mine, yours seems maybe higher, not the same angle (more horizontal) and more in front.
Mine seems more "back" (sorry not my mother tongue). Resulting the downpipe directly in contact with the direction

FR manifold is maybe mandatory even with slight modification for DP
