correct4.0 engine
correct4.2 crank and rods
stock pistons will give you a 4.5, .030 will give you a 4.6, .060 will give you a 4.7aftermarket cam and pistons
you will need to machine the snout off the 4.2 crank so the end looks exactly like the 4.0 crank, this will allow you to use the 4.0 dampersince its a 4.2 crank wont i have to use a 4.2 harmonic damper?
and if i do why would i have to cut off 1cm off the crank snout?
does that mean i need the 4.0 damper?
you will use the 4.0 flywheel, it is required for the crank position sensor, it will bolt right up to the 4.2 crank.. and you will want that complete rotating mass (4.0 balancer and flywheel, and 4.2 crank) to be balanced professionally... if you have the money and means, it may be a good idea to get a ring of metal machined to add mass to the flywheel, this is called an inertia ring... this adds momentum to the flywheel and will greatly increase your torquesince the crank harmonic damper and flywheel is a blanced unit i will have to use all those with the 4.7..... now with the 4.2 flywheel i am gunna have to use the 4.2 starter also or can i use the original 4.0 starter?
