Hi all, just rebuilding my engine with the following mods,
forged pistons
H beam rods
Sti4 heads
front mount
3" exhaust
walbro pump
parralell fuel rails
FPR
300 zx maf
apexi pfc
stainless headers
apexi 555 injecters
Garrett MD321H or T turbo (not decided yet)

There are a few more but i most likely forgot, what i want to know is am i better running it in on standard injecters,ecu,maf and fuel pressure first then fitting the apexi ecu/injecters, maf and trailering it to have it mapped?
Also what running period do you suggest.

Many thanks Rob

 

Anybody?
