I am doin a diy build at home with the help of a couple of engine builder mates
at the moment it is out of 2 engine
a 97 gtb open deck ej20r (i think) and a 90 legacy closed deck ej20g


the gtb has run bearings the bores hav small scrapes but no scratches or garks nd the ej20g is fine just seemd to be really sutty in front rh cylinder

i want to run some racing bearing acl

will the crank in the gtb be ok after running the bearings?
i have the crank from the ej20g closed deck otherwise

if i cnt use the gtb crank will the older one be ok to use with solid lifter heads doin more rpm than it is used to?

its not a real high power build as im using a td05h 16g with full headers exhaust 97 gtb heads im going to use and running using a megasquirt

what would you guys reccomend using parts from both engine?
are the oil pumps different which is better? can you tell me the best parts to use for the engines?

thanks

 

im duin a DIY rebuild at the moment

i have ej20g closed block from legacy
ver5 sti forged pistons
ver4 stiforged rods
wiseco gudgeon pins
standard ej20g legacy version crank

my question is do these cranks come standard forged im pretty sure they do but im just making sure

also are they balanced as standard as the sti and wiseco parts are lighter than the standard pistons and pins

with this combo of parts will i need to rebalance the crank or not
