Hi,
Does anyone have any idea which piston's can be used in an EJ33 build? The reason i ask is i bought a set of Wiseco 92.5's and they came in a box of 6, not just 6 sent, the box was made to hold 6 pistons.
Although the piston has 925 at the end of the part number on the top, i'm worried the pistons are slightly different to those used in a 2.1 stroker build.

Any help would be appreciated.

 

believe the ej33 have over 96mm pistons

So why would a box of 6 92.5 be required by anyone?

 

Could it be that these pistons fit other cars, im sure these arent manufactured just for subarus. Some other yankiee car might use the same size pistons or the dealer might get them cheaper from manufacturer in boxes of 6. I would contact the company you bought them from and ask, if they are the right piston and they only intended on sending 4 i doubt they would expect you to return them as its their mistake and they would have to pay for postage and import duty

 

If you want to post one to me I'll measure it up for you.

 

EG33.

Uses a 96.9mm bore.
