I will picking up a b20z block from a friend. he also has a gsr crank and girdle along with forged gsr rods. what are the benfits of running this kind of setup
plan to get a b16 head to go on top of this

 

find a ls/b20 crank as its a 89mm crank opposed to the 87mm crank found in a gsr

 

it will be 87.2 X 84.. thats the difference mostly. It will still be a good engine, trust me.

 

yea it will still be good and put out good numbers but ur gonna loose 2mm's of stroke and some torque thats about it. i say go for it.

 

correct me if i'm wrong, torque makes power..hences keep the b20 crank..or find a lightned ls crank. Losing 2mm of stroke is a good bit..it will hurt both your whp and wtq..why would you want to switch to a smaller crank anyway.. makes no sense unless your in a bind and need a new crank?

not necessarily EKJavi used a ITR crank in his build found here https://honda-tech.com/zerothread?id=2071065
and made 260.5 hp and 166.8 ft/lb of tq

yeah.. but the question now is would he have made more HP with the LS crank.

imo, yes.

 

going to gsr crank you lose 2mm stroke. less torque. less whp. doubt it will be by much though. should be a strong motor still.

 

good info
