Ok im looking for some low compression pistons mostly the at Nippon ones because of the price. Now all im seeing is b18b with like vtec head comparisons. They say 81mm but how will i know it will fit my b18b1 LS also the same with rings, heres example.

--------------------------------------------------------------------------------------------------
Fits Honda B16A B16B B16A2, B17A, B18A/B, B18C GS-R or B18C5 Type R

These pistons do not work with B20 or B20Z


B16A Block and Head

B18C1 Block and Head
(this part had comparison of the compression outcome with each head)
B18C1 Block and B18c5/B16A Head

B18A/B Block with B18C1 Head
--------------------------------------------------------------------------------------------------

And LS Rods would i need LS bearings is there a difference in the rods? From GSR, Type R

Thanks!

 

Basically almost all bseries pistons swap out. There are some differences in the width where the wrist pins go through, but cheap replicas just make them wider so they will fit everything but the B20s (ie, 84mm bore vs 81 for all others). The main bearings are the same bewteen the B18A/B and B18C1/5, but the rod bearings are different (they are wider for the B18A/B).

 

ok well so i can use the pistons? as long as there 81mm basically same goes for the rings, but as for the bearings there different? *make sure to order bearings that are for an LS motor?


Would these fit?
