1/ try motortakaful.com .... thats where i insure my 95 honda...its etiqa takaful iinm.
2/ pro3 requires quite a high compression to get any power out of it. B16B piston wont be enough to give it the compression it needs. would recommend Toda C2 or Skunk2 Pro2. take note that i have a friend with a B18C-R with 12.5 compression with Pro2 and his VTEC point is at about 7krpm. otherwise wont make any power when set the vtec point lower. i also have another friend with a b18cr with skunk2 tuner 2 cams and making pretty decent amount of power.... take note than when using aftermarket cams, advisable to have adjustable cam pulleys for fine tuning and also aftermarket timing belt like power enterprise or gates racing so that it doesnt break before 80k km... my mechanic told me if i were to fit toda c2 and wanna use honda oem belts, must change every 40k km max.
perhaps u should google for suitable cams for stock bottom B18C-R
b16b piston is a pretty decent upgrade. but quite costly to get it fitted. upah je dah lebih harga piston bro... blom masuk engine oil, gearbox oil, aircond gas etc.
id recommend skipping the b16b piston for now, and get a PnP job done. would be beneficial for the high cams.... b16b piston can masuk later if the engine requires overhauling or something
S300 = good shit.
standard clutch, id recommend something better like the exedy stage 1 or exedy stage 2 (3 or 4 puck) as minimum...but the stock clutch is pretty decent.
h22a injectors oso ok
instead of works, get skunk2 alpha throttle body... and port match ur intake manifold... take note that stock type r intake manifold has a limit it can be port matched... 68mm if not mistaken.... if u get 70mm throttle body, id advise getting skunk2 intake manifold as well and port matching it to 70mm...another favourite option for throttle bodies is the Super90 Throttle body.
spark plugs, up to u... but iinm vtecs use range 7 plugs... OEM plugs are NGK - BCPR7E-11 if not mistaken
timing belt already mentioned above.
air filter again up to ur choice... but... if u have the type r air box... would recommend u check out these DIY Icebox Cold Air Intake mods.
DIY: Icebox how-to - ClubIntegra.com - Acura Integra Forum

and just change the filter element to something like K&N or something.
aluminium rad is ok... but personally.... stock radiator is good enough... perhaps look into low temp thermostat and low temp fan switch.....but if ur having overheating issues, u should get that sorted first before doing any mods.
arp head stud = good shit.
another thing u should look into is oil pressure. quite important for VTECs.. but usually stock oil pressure is ok for type r as they are supposed to have a higher pressure oil pump. otherwise, there is a simple mod out there that u can do to increase the pressure... involves a washer in the pump.. not sure if its applicable for type r... but try researching it.
