Filippo,

I very much doubt that the N53 combustion chamber is any larger in volume than that of the N54, and my cranking compression #s appear to back this up. K



Not the same thing.
Measuring cranking PSI is a dynamic compression.
Measuring static volumes, piston, head gasket, combustion chamber is how a static compression is found.

Dynamic can be affected by port design and cams. Even doing a closed throttle vs open throttle can/should show differences in dynamic.

what was the price? also how long to get your turbos?

Can't comment on price as there were so many changes with my order that we stopped doing itemized invoices lol.

Omar and Xav are great to work with. Shipping is fast from Lebanon surprisingly, about a week pre-pandemic. No clue now. They can advise you better given these have varying levels of custom machining and that's what adds time to the build. Not gonna pretend to know anything about their lead time these days.

I'm sure that doesn't help but there it is anyway.

@Hydra Performance was working on an outlet solution that works with his turbos. Not sure where he is on that. I rolled my own. I still don't understand why an off-the-shelf outlet doesn't seem to work 🤷‍♂️

They've got a setup now, I got a silicone outlet from him for mine, which I finally got around to installing. They have a new setup now though where the 90⁰ elbows are welded on the turbos and the outlets look way easier to install than mine. I had to battle and swear and use some dish soap to get mine on the turbos.

Just ordered a set of HP800 turbos. Engine lost compression on 17T chinesiums at cyl 4 (78psi)
Next week the engine will be opened up to determine the damage.

You lost compression, not 17t chinese turbos, and you are replacing turbos. Why? What's wrong with the turbos?

I didn't lost compression (luckily) but my engine did.

I started a new thread for the rebuild which can be found here.

Besides of that the front core started to leak oil after 1000km already.
Reasons enough to ditch the Chinese turbo's.

Somewhere Omar (@Hydra Performance) had a video link of his 135i doing a hillclimb. I can't find it - anyone know where the post or link for that hillclimb video is? Thanks!
