would a GSR cranshaft fit in a b16a or am I dreaming. I remeber some gu ydoing a write up and saying you could use a b17a crank. But I was wondering if a gsr crank would fit?

 

it will fit in the crank journals but the stroke is too long and you'd put the piston through the head.

b18 a/b/c1/c5, b20 blocks are all taller then a b16 block for this reason.

 

so a gsr crank would work in a ls block?

 

no the gsr and ls have a different stroke thus why people have ls/vtec. LS crank is 89mm. Does anyone know the gsr stroke. Also there are stroker cranks out there with a stroke of 87.2mm. I was thnikng of using a 2mm head gasket and possibly using some different pistons to avoid pistons hitting the head.

 

sorry forgot to mention the stroker crank is for b16a. And as far as I know there is no block modification required such as decking.

 

ya but maybe it uses shorter rods. a stroker kit comes w/ crank, rods and pistons.. so..

and yes, the GSR has a shorter stroke then an LS. but not by much.

 

B18A/bB B20B/Z..
Rod length: 137mm
Stroke: 89mm
R/S: 1.54:1

B18C...
Rod length: 137.9mm
Stroke: 87.2mm
R/S: 1.58:1

 

Ouch! those are some kinda shitty R/S ratios...Just my .02
