Does anyone know if you can put a T1203 piston sleeve kit in a T1202? I know the rods are the same but the crank cases have different part numbers. Can anyone please confirm whether this is possible or not? Thanks.

It has a different part# but the stroke of the engines are the same so you can fit the P/L of the T1203 into the T1202

Hi Rody

Can i just check so part #2BS03010 not compatible with T1202 case, have to use #2AP03010? I am confused as Capricorn (ONE) are saying #2BS03010 works with all their ONE OS engines.

After asking to OS Japan, yes the P/L of the T1202 and T1203 are compatible between each other.

Hi Rody, sorry if this has been asked before but i am new to Nitro Touring. Just to get a final confirmation from an OS Speed engine tuner like yourself, i have both the T1201 and T1202 OS Speed engines and i am wondering if the new 2BS03010 (piston,sleeve,conrod & etc) rebuild kit meant for the T1203 engine will work 100% for both T1201 and T1202 engines or not.

It is getting difficult to find T1201 rebuild kit so i am wondering will the new 2BS03010 rebuild kit work for both T1201 and T1202 engines. If it doesn't 100% fit, what modifications would i need to do to make them fit?

Thank you in advance.

The rebuild kit 2BS03010 will be compatible with the T1202 and T1203 but not possible to fit in the T1201
The rebuild kit for the T1201 can be found here : https://www.worldchampionproducts.co...os-speed-t1201

Hope this has helped you further.
