HI guys i have been thinking of getting a set of
Mitsubishi 6G24 SOHC / DOHC 24v Engines - 10.0 : 1 Compression Raito
Piston Kit is 020" (0.50mm) Oversize, form RPW what would be needed to do to get them in.

it says you need to reboring and honing of engine block.

My question is is this needed.


Thanks in advance Brad

I'm guessing, given that they're bigger pistons, that you'd need to bore the cylinders out to accomodate for the extra size.

then again, i'm no technical genius, so dont quote me on that. lol

im thinking its need because they are piston kit is 020" (0.50mm) Oversize

so next question is can i get a set out of a 3.0 litre Pajero and will they fit straight into my TF.

yeah should do man, so long as the bore is done to accomodate the larger piston (as its 20 thou) and the 6g72 from the pajero and magna are the same according to ACL (use the same bottom end part numbers).

Brad,
If the pistons you are fitting are the same bore(diameter) as the old ones, then a bore isn't necessary.
If they are larger, then you will need to have the cylinders bored out. Any engine rebuilding place will be able to do this for you.

If you are fitting new rings(which is a must with new pistons) then you will need a hone as well. If you are just fitting new rings to an old piston, then hone it as well.

Check your big ends(the big end of the conrod) bearings for wear. There should be light wear marks, but no bad scuffing of scores. Don't check with your finger nail as this will scratch the bearing.
Check the main bearings for wear as well. These are the ones that the crank spins in. :D

If any of these have wear on them, replace them with new ones.

So, summarizing. As a bare minimum, if you fit new rings, and nothing else, hone the bores.

HTH, Chris
