				3.4 to 3.6 using 997 3.8 99mm pistons
			 
 
			Im doing all the homework I can into doing a 3.4 to 3.6 engine conversion.
 Ive found the Wossner pistons and they list all the speca of them (OE specs)
 
 As you are probably aware, to go to 3.6 from 3.4 requires 99mm bore. The 997 3.8 has a 99mm bore.
 
 Can we use these off the shelf pistons for our 3.6 big bore engines?
 
 3.4 996 spec
 
 11.3:1 CR
 15cc bowl in top of piston
 32.3mm compression height.
 
 3.8 997 99mm pistons
 
 11.8 CR
 13.8cc bowl
 33mm compression height
 
 out of interest
 
 3.4 987 S
 7.8cc bowl
 11.1 CR
 32.3mm compression height.
 
 Does the 3.4 996 engine , albeit with a 99mm bore, accept thr 997 S pistons?
