D16Y3 questions need conformation from UK/Europe members or USA if your familiar with

Questions:
1) Wiki states that the D16Y3 uses the same camshaft as D16A6, does this mean i have the ability to install any camshaft that's compatible with a D16A6?
2) I also read that the D16Y3 is already equipt with PM6 pistons and if this is so my CR should be 9:1 right? and if yes is my D16Y3 PM6 pistons the exact mirror image as PM6 piston is USA? don't know why they would be different just asking.
3) Is anyone on this forum from UK/Europe running this specific engine? If yes which motor in the USA can i swap internal parts with or in other words compatible/interchangeable with? or what did you change up internally regarding top/bottom end modifications to build a stronger more HP D16Y3?
Since i didn't find anything helpfull pertaining specifically to the D16Y3 when using the advanced search button and the net would someone who has extensive knowledge or atleast more than me about the D16Y3 PM me or quick reply. I got plans for this engine before i drop in a boosted DOHC ZC which is my end goal in 2 years but want to see what i can do with my current setup in the mean time. Extensive info on my specific motor is slim to none in the USA and I couldn't find any useful thread/build thread anywhere on the net. I messaged bisimoto engineering 7 days ago and still haven't heard a peep but i doubt they would ever answer my questions but got my fingers crossed. If anyone would know they should be the ones who could confirm with their attained knowledge of a variety of d-series engines, well i hope in my case.
Goal: internal mods only >> Boost the D16Y3 with modified top end(heavy port and polish, mild cam, cam gears, springs, retainers etc.), refreshed bottom end(OEM parts) while running 5-10psi low boost with an good tune.
Note: This specific motor came equipt in 1995–1997 Honda Civic MB1 LS (UK/Europe) & 1996–1997 Rover 416 SLI Auto (UK/Europe).

Hello Jason,
Thank you for your interest in Bisimoto technology for your build! Must say you have a very clean looking Wagon and I like the concept of building a rare engine that was not available here in the US market. As for after market support Bisimoto can gladly assist with your entire build, however we would need certain components to design custom parts for your unique engine.Bisimoto can offer for your cylinder head complete disassemble/ clean/ inspection, hand port & polish, Bisimoto Spec full radius competition exhaust valve job, Bisimoto spec multi-angle competition intake valve job, de-shroud valves & polish chambers surface deck to mirror finish, new valve seals and re-assembly. Your good head must be sent in without cam caps to Bisimoto Engineering. At time of arrival Bisimoto can also inspect your valve train components to provide the appropriate Bisimoto Pro springs with titanium retainers and Bisimoto lightweight stainless steel valves. For your camshaft Bisimoto offer performance re-profiling services which your factory camshaft core will be machined and precision grinded to Bisimoto specifications. Bisimoto Level 1.2 would be the most ideal profile for a mild boost project such as yours gaining a superior powerband as well increase turbo spool times.
Another recommendation would be a Bisimoto adjustable cam gear to optimize camshaft timing as well power band to fit your racing needs. Bisimoto cam gears are also the only gears on the market designed and machined with serrations between the two adjustable pieces and held together with ARP hardware making them impossible to slip, protecting your investment.
Pricing(subject to change):
Bisimoto standard Honda head work with porting: $1,049
Bisimoto Pro springs with titanium retainers: starting at $364
Bisimoto lightweight SS valves: starting at $259
Bisimoto Level 1.2 re-profiling service (D-series non-vtec): $369
As for your motor there are quite a few of those Honda/Rover motors running around over here in Germany and I have no problems finding a US equivalent motor and ordering parts from the States. You will probably find that any SOHC 1.6 Non-vtec part will work. If you are looking for specific parts let me know and I can try and find something over here in Germany to get you some numbers to go by.
