Has anyone tried these in A-series motors? Opinions?

Thanks!

No comment (I'm sure they work well, Omega is a reputable name in the UK and I know some motorcycle people who have used them with no problem), but why pay to import pistons when you have aftermarket piston universe is mostly here?

You can go with CP with all the stops or the Wiseco, which is similar priced to the Swiftune (and not the bigger shipping costs). He also has a few wrist pin options (again, you can go with DLC coated tool steel and go down from there).

As a quick add on, Total Seal has a piston repair capability and Venolia has good pistons, but even better they have an extensive inventory of wrist pins to fit all sorts of odd pistons like we have. Also, we have run a few sets of Omega pistons over the past 30 years and they are very durable.

Bob, sorry to say Venolia is no longer in business. They closed the doors last year. They supplied me with pistons for many years but now I am looking for a new supplier.

Am I wrong in thinking that Omega pistons are no longer available? Just looking for other options.

Thanks.

Thanks Gary. Sorry to hear that. A little behind on keeping up and getting my engine building done due to hurricane recovery stuff. Have three of them in boxes ready to put together. May not be accurate as I don't do APT any more but you might be able to get Omegas from them. I've been getting my engine materials from Jack at 7 Enterprises. He's got a good line on competition valve springs for 1275s plus parts for just about any engine. My last set of pistons for my soon to be built 15.1 948 vintage engine started at AE, went through Total Seal to my local guru for shaping and then to me. Complicated, but got a good product. Mike Miller at Comptune would be another place to check. What he doesn't know about these engines would be hard to determine.

Bob

Omega is still in business, not sure where that came from.

Like most industries, the piston world is just a handful of people...

Harvey Crane was the original owner of JE Pistons, he later sold the company to Wayne Brooks and Barry Calvert. Wayne and Barry eventually sold the company to the same group that owns Wiseco pistons some years ago, but they are operated separately. After Wayne's non-compete ran out, he opened up RaceTec/AutoTec pistons and poached some of sharp JE people he had hired and worked for him. Barry Calvert, along with his brother Dave Calvert (both Arias Pistons alumni's), partnered up with Pankl to create CP Pistons (Calvert-Pankl). They have since bought Carrillo rods (Pankl still being the high end brand in NASCAR and F1 engines, with Carrillo's taking on more of the custom and volume work) and Arias Pistons (Nick Arias passed away in 2016). CP has kept the Carrillo and Arias brands alive, and with the Calvert's having worked for Arias for 18 years plus, have interest in it and the brand. Nick Arias and Bob Toros owned Venolia, when Nick left to form his own company. Ross Pistons is also a former Arias alumni.

Diamond Pistons is owned by Trend Performance (Bob Fox, valvetrain guys, invented the Spintron ). Gibtec (popular with some of the Pro Stock racers and other drag racers) is a former Diamond pistons / Trend engineer.

Piston manufacturers in the States. Most will make custom pistons. Some are more advanced than others in terms of tech (CP being what's used in a lot of high end programs along with Mahle (NASCAR, top NHRA teams, factory powersports programs, etc). Diamond has a good market share in the drag racing world and the Arias brand is still big in the sport compact world. Wiseco still has a lock on the powersports sector, and JE is still pretty popular in the automotive world).

CP-Carrillo / Arias - already have made A-Series pistons https://www.cp-carrillo.com/pt-3507-pistons.html / https://ariaspistons.com/
Wiseco - already have made A-Series pistons http://www.wiseco.com/
JE Pistons - already have made A-Series pistons https://www.jepistons.com/
Ross Pistons - probably have made A-Series pistons https://www.rosspistons.com/
Gibtec Pistons - can make them https://gibtecpistons.com/
RaceTec/AutoTec - can make them http://racetecpistons.com/
Diamond Pistons - can make them https://diamondracing.net/
Mahle Pistons (technically international, but have a presence here). - likely not. Not interested for them / would cost too much http://www.us.mahle.com/en/motorsports/
BRC Pistons - likely not http://www.brcperformance.com/index.html
BME Pistons - might have an unfinished forging that will have to be finished elsewhere like Rebco Machine (Kansas) http://www.bmeltd.com/pistons.htm / https://www.manta.com/c/mb5pp5w/rebco-machine-inc (comes recommended by Dave Calvert for modifications / repairs they can't / won't do).

Pretty sure Venolia's staff was aging out and they were losing market share to companies with more advanced manufacturing.

Update;

JE, Wiseco, and Diamond are owned by the same hedge fund (Kinderhook). It was mentioned by someone they are all using Wiseco for their forgings, but all run independently outside that (for now).

They aren't operated that independently. My last three custom sets of JE pistons were ordered in CA and shipped from Ohio.
