[Fot] Spitfire 1300 Piston Rings

Fri Mar 19 02:59:13 MDT 2021

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.

I always ran Total Seal rings in my Pinto and Celica race engines, never had a failure 

I also used special made teflon buttons to center the wrist pins, again, never an issue from them - clips of any kind can and do fail (had 1 failure) 

like so many things we try/do with our engines we all find things that work for us - usually they work for others but, sometimes not 

remember the key, "any significantly advanced technology is totally indistinguishable from magic" 

Cheers all,

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

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. 

Can any of you share your ring choices? 

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

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

Your thoughts are appreciated!
