engine series parts interchangability?

[l3004x4drifta]

gday all. now this is going to seem like a pretty retarded question, but i am new to the 4gseries of motors, and i havent been able to find this info in archives or through google, so here goes: do any of the different 4 cylinder engine families share any interchangable parts? and if so, what parts? intake manifolds, heads, extractors, pistons, etc? thanks in advance, for what must be blindingly obvious to most!.. peace.

Welcome to the forum.
There's plenty of info here about all sorts, but the key is finding it when you want it.
Here's some of the info you're after Ultimate Topic Directory (FAQ TOPICS) (UPDATED 21/11/10)

not sure that answers the question which I think is what bits swap between the 4G3 series SATURN engines? if so its everything with some exceptions. You should stick to one engine though, swapping in one conrod will work but not the best idea etc etc.....

I'm not sure it answers it either, but I read his other posts, and he wants to swap a 4G62 with a 4G54.
So in that particular swap, I'd say nothing for the motor.
That is why I posted the above link.
woops lists motors and drivetrains that are compatible. I thought that may help some?

ok second guess if you mean any 4G? engine nothing swaps between any of them 4G3 $g5 or 4G6, only within a series

edit maybe a flywheel on some 4G5/4G6

[l3004x4drifta]

thanks for the responses guys. i will definitley be seeing if the 4g62 flywheel will fit for the 4g54 i intend to use. are the clutches interchangable between the 4g5's and the 4g6's? thanks again for the help. cheers!

I know that the 4G54's there are 2 different flywheel sizes (wide or Narrow block)
I don't know if the 4G62 comes in both wide and narrow block? As far as I know it's only Narrow block?

In the Ultimate Topic directory link that I posted above, there is a topic on how to measure whether you have wide or narrow block. I'd suggest that would be the best place to start.

Where did the 4G54 you have come from? Was it from an auto? Is that why you want to swap the flywheel?

the 4g54 is from a scorpion. its an astron 2 . both engines are manual, and i thought the 4g62 flywheel would probably be lighter? i intend to remove the balance shafts from the 4g54 and add a thermo fan, so it can rev a bit more easily. and as for the clutches, the throw out bearing is cactus in one of them,so i was wondering on swapping bits around? id also like to know if the 4x4 l200 and l300's share the same gearbox as the scorpion, and if the transfer case will bolt up to the scorp box? im going to the shed tommorow night, so i will prob find out the hard way. ha! again, thanks for any insight you can give. cheers! ps. i had already read rwd engine hop ups

Id guess the Scorpion has a jap box so it should, a new one is better insurance.

id also like to know if the 4x4 l200 and l300's share the same gearbox as the scorpion,

they are japanese made but not the same or if your asking if the bolt pattern is the same your best to measure.

and if the transfer case will bolt up to the scorp box?

no
