Posted by: 914Timo Mar 20 2007, 04:55 AM

I have decided to update my 3,0L six. I have already bought new-to-me cylinders from later 3,2L engine. Now I am going to buy a set of new JE pistons.

Can anybody recommendate any shops ? I have thought to buy them from bird-boys (PelicanParts). Or should I order them directly from JE ??

From bird-boys pages there are no info if I need to measure my cylinders before ordering the pistons. Or do they make only one sice that fits all ?? Do all 3.2s have exactly the same cylinder diameter ??

Thanks,
Timo

Yes, you need to measure your cylinders - they will invariably vary in size at least .0005". Once you have a range of actual measurements, you have to size the piston accordingly to the smallest bore, meaning you will have some loose pistons. The only real way around that is to replate the cylinders and match hone to the new set of pistons. There is no one size fits all JE piston :-)

I would recommend purchasing through EBS Racing - make sure to give them all the measurements so that they can size the piston properly. I myself don't typically sell the JEs sans cylinders...

Ok, thought so too. I will measure my cylinders and give a call to EBS.

Many thanks, Charles
