I do not. I went with Total Seal Steel rings with a custom napier cut second ring. These are custom bore pistons at 3.560 so it will make for a nice and high oil tension as well. I went with Trend H13 tool steel .200 wall wrist pins as well. With the Manley billet rods this thing should not even break a sweat at 1000rwhp.I couldn't tell from the picture. Do you have to run a support rail for the oil ring?
And what (and whose) rings did you decide to go with?
Have you weighed them? Last set of CP pistons I worked with were absolutely dead on from piston to piston with weight. No adjustments needed.
Siebert performance is doing the machine work. I'm putting it together.Very nice. Who is building the engine? You? Make a build thread!
You only need to upgrade pistons for around 1k rwhp anyway right? kinda new to having a termi!
We are waiting to hear back from total seal for the custom ring package price. To be honest the rings killed me when I had them setup, but if Real Street can work something out it will be extremely affordable.Now for the big ? Price?
A billet manley rod will have zero issues with the extra weight. I'd MUCH prefer a thick skirt and wrist pin over some "weight savings". If this was an all out NA car I would agree. .180 Tool steel will also work on a blower combo as they typically don't have the same RPM stress associated with turbo cars I however would want a much thicker skirt.436 grams is getting a bit on the heafty side. The .200 wall wristpin will add even more. That will put more loading on the rods.
When I bought my pistons from CP all I told them was I wanted a 23cc "blower" piston for a Boss block this is what they sent me. .300 top down ring, .165 skirts, .180 wall wrist pins. They all weighed 399 grams.
Modmax pistons weighed a whopping 455 grams
CP's are very nice pistons.

I plan to push 25+ lbs of boost. The piston is set to handle 1krwhp and well beyond thus the reason for the large wrist pins as well. I'll be running Brian Tooley springs. They have intake reliefs, and that's still being discussed. Most people suggest bore x .007
