The perfect N/A build??

a 0.5mm overbore will give you approx 50cc extra capacity...

stock is 82.7mm = 1998cc
first overbore is 83mm = 2011cc
next overbore (this is an unusual size) is 83.5mm = 2037
next overbore is 84mm = 2062cc

so a 1.3mm overbore gives you 64cc
0.5mm would only give you 24cc
 
in the proccess of getting a engine built at the moment
maxi pistons,rods,single piece valves,uprated springs, cat cam 403's,
had vvt delete with vernier pulleys on my 172 engine and got very good results so will probably do the same on this
will keep posted once it is done

Please Do! I am going to undertake a similar build at the end of this year.

oops my bad should have been 1.0mm!!! (just seeing if anyone spotted yesterdays deliberate mistake)

which gives approx 50cc or 2047cc
