thanx for the info inferno, i just found out a couple of days ago that my 2tg use to be fuel injected. but now it has the twin carby setup. so this must mean its a late 2tg model, the mechanic that is fixing my 2tg has just found a head for it. so if i wished to have higher comp. i would need nu pistons? how much would it cost to install a 3t crank, so it would stroke out to 1.8ltr. i wouldnt need to get anything machined as it is a later model, and should fit straight in? or wont it?
