Quoting autotek:
Hi, just want to know. The 4g63 engine on the galants non turbo are the same as the turbo?? wich components change i know thw pistons are , but anithing else?? and if it has an automatic tranny does this make difference too?? let me know. /ubbthreads/images/graemlins/confused.gif
There are a few differences between the 2, first off I am assuming that you are just refering to the motor itself. As for the block, It and the pistons are different. The turbo block has piston squirters in it to cool the pistons from the extra heat that is built up from the added pressue of the turbo. And the pistons them self have a different top on them for the different compression ratio's that they run. The turbo engine runs a lower compression ratio for the increase in pressure from the Induction of air by the turbo.
With the rest of the long block there are small differences. The water coolant pipes, the oil pans, the intakes,the injectors and the fuel press reg, the front and rear motor mounts,and the cams are different between the turbo and non. As for the cams, there is such a small difference, that you can interchange them between stock motors.
As for the automatic trans model, depending on the vin # and the year, there are two different horse powers for the Non turbo engine. I don't remeber these off the top of my head tho. As for any other differences, on the flywheel end of the crank, there is a bushing right in the end of the crank that the torque converter pin rides in for alignment. this has to be removed if you are going to swap the motor from an auto to a manual. Also you need to source the small aligment dowl that lines up the flywheel.
The starter plate that is bolted to the back of the block behind the flywheel is different on some of the auto models comapred to the manual ones. You need to match these up aswell when doing a swap or conversion. I have also fond a few auto models have a different cone on the starter's too.
Im sure there are other things, but this is all that I could think of at the moment.
