Stock B16A2, just been picked apart, and the rod bearings looked like HELL! At one
side, the two bearings had melted together..

So, engine will now be fully built, either with high-comp internals, or forged.. depends
on NA or forced induction. New connecting rods, crankshaft, valves, cams etc.

I have only one online shop i trust 100%, wich is King Motorsport.

These are the choices I have for my B16:

Brian Crower:
B16 Forged 4340 84.5mm Stroker Crank [BCROW-BC5018]
All Vehicles $ 663.00
B16 Light Weight Forged 4340 84.5mm Stroker Crank [BCROW-BC5018LW]
All Vehicles $ 722.00
B18 & B20 Forged 4340 92mm Stroker Crank [BCROW-BC5020]
All Vehicles $ 663.00
B18 & B20 Forged 4340 95mm Stroker Crank [BCROW-BC5019]
All Vehicles $ 663.00
B18 & B20 Light Weight Forged 4340 92mm Stroker Crank [BCROW-BC5020LW]
All Vehicles

There has been no wear to the block itself, so it should accept a new one right in - right?

Wich one to choose? Neither?

depends what your doing, and what your goal is. i say use a stock crank, micro polish and balanced, try to be more specific

Inferno^

The crank i have is useless, unless polished and balanced.

My goal is 180-200 whp. And I don't now how many mm the stock crank is, hence
why i'm wondering wich of the ones i listed above will be right for my build.

rick_rabies

i would get the one you have or another oem crank and micropolished and balanced, you dont need a fancy crank unless you plan on 1000hp or something crazy, parachutes, full flame suits, 12 point cage..

The thing is, here in Norway - it is really expensive to do this, and to buy a new one
from the states is almost the same cost-wise

But if i choose to do this, where would you suggest i get new rod bearings to fit the
smaller crank?

rick_rabies

to fit the oem crank?
there is King Race bearings
ACL bearings
OEM bearings, etc

But still, wich of the listed crank's at Kings is recommended? I see there are different
sizes, and i would like to now wich size to go for?

do you mean which stroke?

b16= 77mm
b18=89mm
b20=89mm
b18c=87mm
b17=81mm

these are all the stroke off my head.
so if you have a b16 block 77mm is the crank you need

Inferno^

Thank you!

How is the stroke of the crank measured, where the rod bearings used to lay?

I beleive its measured from the center of the crankshaft to the center of the rod journal.
you are complicating it, all the numbers are already given even for aftermarket cranks so aint no need to measure, but its good info to know, I will check my facts and get back. but the important thing to know is rod stroke ratio, but that still is unecessary. you can figure this out by dividing the rod length by the stroke and you will get the ratio. there might be more knowledgeable people here about this.
