justy like the title says, a few months ago i blew a piston in my b16 motor and i have some je pistons out of a gsr and i was wondering if they would work in my block??

ricanem1

sry i forgot t oclarigy gsr as in b18c1 not the b17 gsr.

as long as theyre standard bore of 81mm yes
Id just get some new rings for them

ricanem1

wil they drop right in on my b16 rods? or is there anything different i have to do? would it be a direct drop?

pdiggitydogg

Aftermarket companies do not make "gsr" or "b16" pistons.
They just make Honda b series (81mm+)

So the answer again, is yes they are a direct install. I recommend you hone your block and have it inspected for damage before you swap anything over

thanks for the info man.. i was just confused because it seems like everyone has something different to say..

That's not entirely true. Assuming the pistons are designed to be a direct fit for the stock GS-R rods, they won't fit the stock B16A rods, and vice versa.

Also, depending upon how "aggressive" the pistons are, you may end up with a lower compression ratio than what the B16A pistons were providing.

when you say they won't fit the gsr rods what do you mean? because i have crower gsr rods and some stock b16 rods? how can i make them work in my b16 block?

ricanem1

they are je 9.1 pistons and crower gsr rods. im trying to get my car running the cheapest way possible..because the b16 blew a piston.. nd i don't have alot of money..

You will have to mill the B16A rods in order to install GS-R pistons on them.

You'll also end up with quite a low compression ratio, so unless this is a turbo setup, I'd recommend choosing a different solution.

ricanem1

im sorry im not quite understanding you what do you mena by mill?

ricanem1

this is a turbo set up btw.

you know ive never heard/seen that before
when i was looking at pistons, wiseco and je all had the same part numbers for any b series just with various piston styles (flat, dish, dome).

JE does appear to list the same part numbers, so I'm curious what rods they're designed for.

I know that in the case of OEM GS-R or Type-R pistons, stock B16A rods must be milled in order for the pistons to be installed.

Material must be removed from both sides of the small end of the rod in order for the piston to fit. This is true for OEM pistons/rods, but I'm not certain what the JE pistons are designed to fit.

As for the compression ratio, even for a turbo setup, it will be quite low with the JE pistons.
