I have used Total Seal piston rings many times, and that is my "go to" pist=
on ring.

Hello Amici,
=C2=A0

A discussion with my machine shop man led to some thoughts about piston rin=
g selection.

=C2=A0

He recommended getting in touch with Total Seal. I of course took a look at=
 their website to discover a mind boggling selection of ring types.

=C2=A0

Can any of you share your ring choices?

=C2=A0

I will be having JE Pistons make a custom set of forged pistons for me.

=C2=A0

I am in need of ring thickness dimensions as well. Should this come from th=
e factory (GT6) pistons I currently have in the car?

=C2=A0

Your thoughts are appreciated!

if JE are making pistons, surely they will supply rings???

In general, ring & piston design has improved a lot in recent decades

in most cases, you will head for a nitrided steel top ring, a steel centre
ring (possibly filled with something) and a 3-piece segmented oil ring

in many cases, they can now make a perfectly satisfactory top and second
ring at or under 1mm in thickness. Generally, the thinner it is, the lower
the friction but really thin rings require super careful honing and bed-in

best practise is to not have any slots behind the oil ring, but rather a
ring of small holes

some piston makers have all sorts of clever micro 'tricks" like
anti-flutter grooves they machine in the lands between the rings

Whomever supplies the rings will specify the final hone finish required

best practise is to use double "spiro-locks" to retain the gudgeon pin

JE Pistons are owning Pro Seal piston rings and gaskets, and maybe one can buy JE Pistons fitted with this brand of rings. On the Pro Seal website, you can find information about the ring services that JE Pistons is offering. 

PS :Total Seal is a misleading name : most of their rings are NOT gapless.

Hello Amici, 

A discussion with my machine shop man led to some thoughts about piston ring selection. 

He recommended getting in touch with Total Seal. I of course took a look at their website to discover a mind boggling selection of ring types. 

I am in need of ring thickness dimensions as well. Should this come from the factory (GT6) pistons I currently have in the car?

Piston ring flutter is a hard to detect phenomenon that will allow a lot of=
 pressure loss into the crankcase.
Rings that are too thin will tend to flutter due to less spring pressure. =
=C2=A0The higher the piston speeds as in the wet sleeve TR engine, the more=
 likely flutter is to occur. =C2=A0
I'm not sure about the Spitfire engine (too lazy to do the math before coff=
ee) but if you choose thin rings such as those used in the Total Seal set u=
p, the more likely you are to get flutter. The Total Seal solution uses two=
 half-height rings with the gap oriented 180 degrees from each other. =C2=
=A0IMHO this is asking for flutter.
Having said that, when they work they work well. We used them successfully =
in a 948 Sprite and a 1.8 liter Integra.
