Hi from the UK and welcome to HDF. What do you mean by '88'? If you mean 88 cubic inches, then follow John's advice and contact Hammer, as they have several big-bore kits. They also have an excellent website on tuning Sportsters and are very popular in here. If you mean 1988, tell us what model year your bike is.

Not sure what 88 CI cylinders and Pistons you are asking about.
It might help to know what year 883 you have.
Axtell has a 88 inch kit for the XLs.

Hammer Performance offers 88 ci kits using the Axtell cylinders-

Not a "bolt on" upgrade, you would have to split the cases to machine them
"Case boring is required for installation: either kit requires the spigot holes to be opened up to 4.005" at a depth of 1.5""
Hammer Performance does offer 1275 cc kits that do not require splitting the cases-
