Hey guys, I've got a quick question. I've already done a search and came up with everything from blocks to trannies to ecus, rods, pistons, etc. what exactly does PR3 denote? I just bought a B16 block from Tybrid Performance and they are telling me that "it says PR3 all over it". Will this block mount up to an OBD1 head and hydro tranny? I'm trying to swap this block into an eg hatch. any help is appreciated!

PR3 is an ecu
my jdm d15b says p08 all over it too
the block head and trans match up long as its b series

its the ecu code and also stamped on the head and accesory brackets

cool, so I guess the block will work. also, this guy says that the block is stamped as a B16B, but he knows for a fact it is a B16A because of the fact that it says 'PR3' all over it. sounds kinda shady to me, what do you guys think?

i'd assume they use the same ecu?

meehh. but all i know is dseries so dont take my word for it!!
