Hey guys im debating on boring out my engine but im having trouble finding out what size pistons to go with or a kit that has everything Id need. Has anyone else doing this with a 200t and if so what size did you go with? I have some places around that can do it for me, just need the parts before I pull the trigger on it.

thanks,
Zach
 
Zach, do you know for sure that the pistons are too worn or that the bores are oversized, or are you just exploring possibilities at this stage? First thing to do is to measure pistons, bores and clearances to see if they are within limits or something has to go. If you do need to re-bore it, you will probably need 0.5mm O/S so search for those and see what's around, but take the barrels to the machinist first and have him carefully measure the barrels to see if they will clean up at 0.5mm over.

If you are looking for a performance upgrade with a bigger bore, that's a little more tricky, and involves more work, but anything is possible.
 
Im going to be getting into the engine soon, I dont think that they will be overly worn out but I plan to replace anyways. What I really wanted to know is it its worth the hassle to bore it over a little and get new pistons. Im not sure and have not seen anything about others doing it yet to see if the gain is worth the money and hassle.
 
It all comes down to how good, or bad. yours are. If they are in spec, there's not much of a benefit for the cost involved but if they are worn and scored it's a different story.

You'll know when you open her up and see what's going on.
