4G63 Beefing up help.....
 

Hello everybody,

I need some help of beefing up my engine. I currently run a 2.0 NT at our local dirt track. My engine is stock with only 41k miles on it. Need to find some ideas on beefing this thing up over the winter time. How much should I bore it out? What type of racing pistons and rods? Strong head gaskets so I will not blow any? Cams? Air flow? Please help. Any chance of getting a 2.4 block and using the 2.0 head on it?

yup....just about anymitsu motor is interference. I know...kinda sucks

the limit will be your bank manager (or wife).
Stroker crank, domed pistons, port and polish, 3 angle valve grind, custom cam/ sprocket advance valve timing.
And a turbo.
