Anyone use these pistons and Cyls? Advice Please
 

Hello.
I'm looking at a set of Pistons and Cyls on E-Bay and they seem very inexpensive compared to others on the market:

Has anyone used these before?
Is this a case of "You get what you pay for" ?
Am I asking for trouble?
Any opinions or advice would be greatly appreciated!

thank you in advance -

I think you answered you own question..you do get what you pay for. I had a 3.2 short stroke built up with custom jugs/plated by mahle and JE pistons. The car ran great but puffed smoke almost everytime I started it. I was unhappy and so was my mechanic. I replaced the pistons and cylinders with a Mahle max moritz set from Mahle. The engine never smokes now even after sitting for weeks. Do it right the first time.

NPR is Nippon Piston Ring. I havent seen the name is some time but they use to, in the 80s, make P/Cs for 356, 914, and VW application.

Made in China? http://www.356registry.com/forum/viewtopic.php?t=10960&highlight=performance+piston s

Not made in China ----

Made in Japan

Interesting: Looks like Toyota motor Corp. is a major share holder in the company.

Vinny, I don't know where the kit on ebay is made. The ebay seller is selling "AA performance Pistons", the poster on the 356 board used chinese made kit by AA. I'd be very careful what you buy from ebay, verifiy what is being sold before you buy.

This is what Henry told me.

Posts: 3,172 We were given a set to inspect and the results of that inspection were good.
A&A has been in the Porsche after market piston and cylinder business for perhaps 10-12 years. Their main product was an 86 mm 356/912 kit.
Those products have proven themselves over the years to be a top quality replacement.
We see little or no issue in using the A&A products as long as you QC the products before installing them.
We were completely satisfied with the products we received and will probably offer these products for sale in the near future.
It is our policy to test products before we sell them so we built a 73 2.4 using these P&Cs as a test mule.
So far they are performing well and we anticipate that they will offer good service for years to come.
If the choice is used Mahles near the wear limit or the new A&A products, I would opt for the new A&A.
They offer 2 compression ratios for long and short stroke cranks. The high compression pistons on the long crank will theoretically produce over 10:1. These are cast pistons and I believe this application may exceed the limits of any cast piston. This concern is based on years of using 2.2 E pistons on a long stroke crank with less than satisfactory results. If you want high compression I recommend the A&A biral cylinders with JE or equivalent pistons.
In conclusion: The A&A piston and cylinder set is a nice option if budget is a primary concern. In today's economy it generally is.

I haven't made my mind up yet because i need to dismantle my engine and check tolerances, if budget dictates it my be on the cards.

mahle has just gone through the roof with the fall in the aussie dollar.
