f series box fits any bp engine. it will break with the aimed 300whp.

na headers, you'd need to cut off all the runners and start again. only using the bolt up plate to the head.

b6 and bp rods will not support 300whp.

his pistons will not support 300hp once you boost it to 17psi+ to gain 300whp.

davo, he has the same engine as us. think we can get 300whp from a ecu, turbo and some piping? um no...

full engine rebuild.
forged pistons.
billet rods.
adjustable cam gears (to decrease valve overlap).
full standalone ecu.
turbo.
turbo exhaust manifold (to be made).
lots of piping.
intercooler.
dump pipe (to be made).
exhaust.
fuel pump (dounno enough about sephia to know if stock one will survive).
fuel pressure regulator.
bigger injectors (maybe rx7 460cc ones if aiming at 300whp).
oil and water feed lines (holes will need to be drilled into the block).
oil and water return lines (1 hole in the sump and 1 hole in the header bypass pipe will need to be drilled).

and heaps of stuff i've forgotten off the top of my head.

and if doing competition work like rallying:-
remote oil filter.
oil cooler.
mazdaspeed oil pump (flows 30% more).
alloy radiator.
all new water pipes.

p.s. and you don't need 300whp for rallying. 100whp will do it.
