Hey guys I just need some info, I am re-building a JP S1 and was wondering if I could put an S3 Piston, sleeve and conrod in it. I have heard that the conrod is longer in the S3 but I have compared them and I don't see any difference.

Hope this dosen't sound crazy

Thnx 4 any info in advance

where are getting your piston and sleeves from??

Corse-R

Main difference between S1 and S3 P/S is the construction of the piston, all other parameter remain the same. You can put without any kind of problem an S3 P/S in your S1 engine, in fact will be converted into an S3 engine.

So really the main difference between the S1 and S3 is the sleeve config and everthing else is the same.

Is that right

Corse-R

In few words, in your JP engine, piston config was the main difference, but in plain Novarossi engines, was another change that made the difference in performance higher, was the crankshaft with more timing on the intake.

But in your engine was the unique difference and of course a higher price tag, too.
