some of you know i have a b17a1 motor that im currently rebuilding
and wondering if anyone knows if the

pr3 rings and pistons will work with the b17a1 block?

 

yes they willl

 

i think the only difference between the b16a and b17a is the crankshaft the 1.6 being stroked .1L to make 1.7

correct me if im wrong

 

Crank is the same.
Rods are different.

 

ahh yes. been so long since iv been into the gsr tried buying 2 in 2003 got fed up and bought a rs and got a jdmb16 swap

 

alright mods this thread can be deleted got the answer i needed.

 

WRONG!

the crank, rods and pistons are different from a b16. only the block casting is the same.

this is the info i got from the Zeal Autowerks calculator:

Crank Stroke
B16A - 77.40mm
B17A - 81.40mm

Connecting Rod Length
B16A - 134.00mm
B17A - 132.00mm

Piston Dome.
B16A PR3 - 6.03cc
B16A P30 - 6.93cc
B17A P61 - 0.00cc

PR3 pistons can be used on P61 crank and rods in a b16/17 block. this should net a compression ratio of high 10's. if you bore out the cylinders .5mm (which would be a good idea) and take .25mm off the deck. you should hit 11:1.

 

thanks buff anyone know any place in scarborough or close by that i can take the block to ?

 

Take it to canadian cylinder head.

 

Good guys!
