EJ22 Turbo pistons
I want to build a turbo svx motor and the idea of fitting these pistons greatly appeal to me over forged custom pistons. As you all know There is no documented fact of this ever been done. I would like to change that. All I need to discover this possibility is a used svx piston in a standard bore B or C.
I have a 2.2 turbo shortblock ready to fit it into. If anyone knows where i can get this svx piston please let me know.

They ARE the same bore and stroke....
the EG33 is basically a EJ22 with 2 more cylinders

I just paypaled tomsvx he's got the piston. Yes the bore and stroke are the same but if the rods are different it might not work. as soon as i get this piston i will be able to find out for sure. Ill post the results.

Thanks guys. Im waiting for the piston Tomsvx sent me. if it dosent have the pin i will need it too. I already took the heads and pistons off the 2.2 block. So far I have been comparing specs from the ej22 manual and the svx manual. the piston diameters,bore diameters and clearances are identical but I cant compare the piston pin diameter since the svx notes i have are missing that data. The 2.2 pin diameter is 22.994 - 23.000 mm. Can anyone confirm this to be the size of the svx pin? There are other things to compare as well like the piston skirt length and conecting rod width and length and if the piston sticks out past the deck. I cant wait to get the piston so i can install it on the 2.2 block and answer all these questions.

Guess what fellas, The pistons are a direct fit. were in buisness. I installed the svx piston in the ej22t block and it fit like a glove the piston protrudes a tiny bit over the deck but the turbo piston is flush at the deck that means that the turbo piston will not protrude over the deck in the 3.3.
Yeah Baby! If your cylinders are good all you need is a light hone, the turbo pistons, rings and pins an you got lower compression. I would like to calculate what the compression will be with the 3.3 heads. help me figure this out guys. I can cc my ej22t heads. Can the commpresion be figured out if we had both the 3.3 and 2.2 CC volumes. The ej22t has 8.0:1 compression. lets say the ej33's CC has 5 more cc's than the 2.2 heads what would the commpression be then (obviously lower)? Lets figure this thing out. Later, Obi
