I can state for fact that Charles will stand behind his product.
He went out of his way to make everything better than new... you don't get that kind of service anywhere else....A few dollars more but worth every penny. |

Haven't used 'em, haven't had a chance to measure them either, but I fondled one at RIMCO earlier this year. They appear to be a knock-off casting of a T4 cylinder shape...very light, of course, and the plating, to my admittedly untrained eye, looked even and nicely honed. RIMCO wanted ~$600 for four... European Motorworks gets $700-ish...prolly all the same manufacturer. Next motor is probably gonna get some 100mm EMPI birals I have laying around or I might give them a try.

Hopefully in the future you'll have alusil cylinders... Just like Porsche did with 944 cylinders, silicon actually cast into the aluminum inside the cylinder walls. That would be bitchin!

Remmelle (sp?) makes alusil cylinders in France for the type 4.
The problem with alusil is that they work fine, as long as you don't get them hot. If they get hot, they go to crap. There is a reason why Porsche never used alusil again on an aircooled engine after the 911SC. |

Getting a quality product out of China is very difficult. My experience has been that if you give an inch, they will take a mile. Quality is great as long as you are standing over them and watching the whole process, day in , day out. But the motiviation for profit is very powerful to Chinese businessmen (as it is for businessmen everywhere), but Chinas' "industry standards" are literally generations behind the rest of the developed world. Cost cutting will be in the works. Cheaper alloys and other raw materials will be incorporated everywhere that traceability is difficult.
Even if LN Engineering attempted to get their own fully developed design made in China, they would have great difficulty getting strict adherance to their process, materials specs etc unless they sent a guy to stand over them year round. |

this is a bump to 2008...
I had some molded plastic parts made in china. they were for a mini sub inspection robot. depth, pressure and a wide range of temp required a "special secret sauce "plastic. teh first batch of parts were great. we had a VIP demo (dog and pony show) scheduled with the navy just after we shipped the last product built with the first production run parts. the next batch arrived just in time so me and my 2 best techs stayed all night to build 2 robots for the demo. at 4am we tested both subs in the tank and all was well. the next day when I arrived at the base with my demo subs, all the screws had popped out and the sub was a pile of junk. Upon investigation we discovered that the material was not what we had spec'd AND supplied to the mfgr . the the plant manager sold my plastic on the black market and substituted some cheap stuff. many trips to china later, the issue continued to pop up. |

This is the common 3rd world thinking....cuz hardly anyone gets caught or faces any legal issues doing it.
Why do you think all those Chinese schools fell down? Hardly any cement in the concrete mix! I try to buy the best I can afford so if you can't afford Nikkies then try out the Chinese cylinders and let us know how it works out. |

The fact is Chinese parts are here.. I fought long and hard to keep them away from the TIV for as long as possible and we held them off for 5+ years.
The issue with Chinese made parts is the QC level. The main problem is the guys that are making engine parts there don't use them and don't build engines with them so they have no first hand experience with how well they work. The key to having parts made in China is to deal with a company that will work with you on QC levels and make sure that each and every part is inspected and measured, assume nothing. The Chinese are ruthless bastards- if you send back parts that don't meet your tolerances they'll just sell them to your competitor cheaper and he usually won't care if they are junk or not! Lots of "Backdoor" parts come from China and most end up on Ebay. Most of my engines and engine kits only have a single Chinese part in their composition and thats the connecting rods.. I still offer a "Made in USA" engine with all aftermarket parts being made from US based materials in US factories, but it does cost more. In short I have used the Chinese to make rapid prototypes for test purposes and to make some "bling" accessories that have no real function.. Recently we sent one of our lower buck exhaust systems there for the 356 conversion to see if it could be made cheaper and still function as well on a 140 HP engine, I'll know soon. Like I said, the parts are here so instead of fighting the bastards we decided to make the best of it and try to make them meet our tolerances, most of the time that requires a full rebuild of the part |

Take along a GOOD bore gauge and a GOOD magnifying glass to see where and if the chrome plating is flaking at the top and bottom of the cylinders.
I like the Sunnen bore gauge my self. And be willing to MAKE THEM open up a bunch of boxes of cylinders until one set meets your expectations. This assumes you know what to look for in a nicasil style cylinder. Cause ya can't machine them once bought. Machining the length will cut into the chrome and make it flake off at the open ends of the cylinder. In essence. you build the engine around the length of the cylinder. THEN you have to have your after market piston manufacturer make you a custom set of pistons to a 911 spec to be compatible with these cylinders. Aluminum cylinders take a very different piston profile that a cast iron cylinder to be correct. Unless QSC now sells pistons to match their cylinders these days. THEN you have to know what torque specification to clamp them down with. Cause these ain't cast iron cylinders and the expansion rate and expansion length is vastly different from a stock cylinder. Hence different torque values. And you will also have to source a ring pack from your piston supplier that is compatible with a chrome lined bore. The Chicom pistons they sell with some of their cylinder kits flat don't work for ANY performance engine.(Tin coated shit) If your into experimenting and you have the resources to do that... head on. Odds are... it may not work well first time out. They are fun to play with. Just expensive as hell until you have the learning curve down. How much R&D are you willing to do...??????? Just something to think about. Now back to my hole......... Clayton |

I tried the china 96mm cast iron from AA. they are OK for 250. I dont thoink this fake nikie thing is worth the risk unless you have surpluss money to test it out.
