I`ve taken out my dremmel and read up a little bit on port polishing, i then ported my liner as shown in pics
put it back togeather and started it up and i feel like the truck revs alot better,

Not content i striped it back down and
took out the con-rod and knife edged and polished it then i went on to the crank and put three grooves on the back of it and done some polishing on it built it up and it now screams and is mental to drive has anyone done this on a cen mg before?
I was going to buy an 18 for it but with this much power from the stock engine i wont have to
i was running on odonnell 25% before any porting and could only just about pull wheelies
ive since ran out and have been using odonnell 10% and its lifting the front wheels and riding on the wheelie bar on tarmac!

that looks real good! i hope ya have fun!
