i just bought weisco 90mm pistons 12.0.1 from a friend and darton sleeves. will this be able to run on pump gas?? are u going to need to upgrade the ingition?? any other equipment needed to make the motor run propley??

 

What engine?

 

jdm b16 sir 2

 

I would have to say no. 90mm in a prelude motor is pushing it.

 

holy, holy, holy, holy.... crap. I'm pretty sure that 90mm isn't possible in a B16, unless you remove everything inside the water jacket, get new sleeves, and just use it as as drag car. But then you're talking about some major $$$ and modification issues.

 

with .0002 between bore centers I dont se it happening unless you offset bore it




.118 is 87mm
.0002 is 90mm

sorry

 

Pictures would be nice!

 

i have seen an 86 mm bore, but even then they say its hard to seal the hg. but damn a 90 mm bore is freagin huge! show us pics of the pistons please

 

90mm bore is like NSX size piston.

like everyone else says, i think it would be foolish to try and attempt this feat.

ive heard 87mm bore in a LS block.

 

87mm can be done on any B-series resleeved, but thats the absolute max..else your sleeves would look like the Audi logo....

 

try it... i dare u

 

its not going to work on B series.

 

mabe yes this could work but you would have to buy a custom crank to move the cylinders apart from each other more so their would be less room between the outside cylinders and the water jacket housing right that could work but you would have to swallow the big one, and they usally like alot of cash also

It is impossible, even with offset bore, cylinder head combustion chamber need alot of work and depend how much offset.
Offset bore sleeves is for boost.

If you want "HUGE BORE NA", build a H-Series + deck plate or K-series.

 

How you going to move the mains on the block?

Not possible...

Maybe one day someone will come out with an aftermarket block that has bigger bore spacing and will support a larger bore, but nothing would be OEM in there.

You wouldn't get a custom crank, all you need with an offset bore block is offset extra thick rods.

 

Who told you to get these pistons?If you can return them bro and even though there is a restocking fee because you might have a tough time selling those.

ok 87mm is pushing it on a allmotor engine 90mm will not, WILL NOT seal you will have more trouble with that setup than you will with anything else.

LOL. I've seen a 90mm H-series Road race motor do some serious damage. So, it seals just fine.


MAX_CFM I love AutoCAD

im pretty sure he was talking about B-Series motors...

 

No piston company in there right mind would make a 90mm piston for a b16. Not sure what you bought.
