B16A with LS pistons?
 

k, does anyone think this is a bad idea or wont work? just trying to get some feed back here. the idea is that when i turbo my B16 that i will burn the ringlands off, or that the rings will be bad to begin with (have a friend that this happened to) so i should get new ring to 'freshen up' the engine. but if the compression is at 10.2:1 i will probly destroy them anyway, so i was thinking of putting the LS/PR4 pistons in (like a 9.2:1 in the LS motor) then it will be a little more detination resistan and i can boost more. am i making sence? hope so...

no im not going to buy forged pistons, SO DONT SUGGEST IT!!!

Re:B16A with LS pistons?
 

i don't think the compression will be that low because of the b16 combustion chamber. but i have never seen it done and am very curious.

Re:B16A with LS pistons?
 

no no no, the ls pistons are too low of compression for the B16a, I am pretty sure its like 8.6 or so with pr4 pistons in a pr3 block/head.

You will be fine, just run 6 psi, and keep the timing respectable and you wont break any ring lands.

There's a girl in my car club (Team Sol Co) with a 94 vtec del sol that is pushing a stock b16 motor... at 9 psi, it is with the turbonetics kit...
She's even running rich enough to dump sparks out the exhaust, and the motor still isn't detonating. Last I knew she was around 95,000 miles to...

So I wouldn't worry to much about detonation :)

Re:B16A with LS pistons?
 

wow 8.6:1??? thats gay...

6psi?? thats gay too...

so a thicker head gasket then?

---- Jeff is right about 8.6:1, damn!

anyone know where i can get some 92-93 GSR pistons? that would be ~9.0:1...

Re:B16A with LS pistons?
 

you should try napa or a honda dealer on the gsr pistons. Probably cost about as much as forged ones though.

Re:B16A with LS pistons?
 

yeah not worth it. im just going to go with a thicker head gasket i think...this sucks there was a set of LS pistons w/rods for 5bucks on ebay :o

Re:B16A with LS pistons?
 

o well, you win some and you lose some!

Re:B16A with LS pistons?
 

you guys are HIGH!

they'd be like $150 for a set new from acura...
sheesh!

Re:B16A with LS pistons?
 

more like 250

you need to order new rings too....

i say keep the b16 pistons

Re:B16A with LS pistons?
 

if you put p72 gsr b18c1 piston it will be 8.9:1 this will be easier to find.

Re:B16A with LS pistons?
 

i dont know were you get your info but the gsr even usdm isnt 9.7:1 thats about .3 off of the actual CR which is 10.0:1 and thats the 93 gsr. the 94-and up also have a CR of 10.0:1 as you ca see from the chart:

Re:B16A with LS pistons?
 

I think you need to brush up on your info... We are talking about putting in different OEM pistons in the B16a, trying to find a decent compression ratio. Putting a GSR piston that is rated at 10.1 in a GSR doesnt mean its going to be 10.1 in a B16a, they have different deck heights and strokes.

This is a great tool to find out compression ratios using mix matched parts.

thanks for xlear that up jeff
