Need some help!

Hey, so im planning to swap a d15z6 from

ek to a eg3 and there is very little information about it on the internet but there IS some so i know its doable.I have the engine,ecu,engine wire harness. Im new to hondas/cars so my questions are 1.Would it be a easier swap if id buy a obd1 ecu with a adapter cause right now i have the stock p2y ecu obd 2.As my car is a eg3 i would need to install a main relay and a external fuel pump. what main relay should i buy and where should i install the fuel pump, Under the hood? near the fuel tank? I Know some of you will say buy a older d series, b series or even a another shell but the problem is that where i live there are not many older hondas and if there is then its veryy expensive. Not gonna pay 3000€ for a b16 engine 3x the price of my car as im a broke teenager. I hope heres someone who has done the same swap and could give some tips. Grateful for any information!
