Has anyone experience wiht the 96mm Big Bore Kit from Ebay, see here: http://cgi.ebay.com/ebaymotors/ws/eBayISAP...em=180377984565. Thanks, Juergen The price is nice. Here is what I have heard from Jake...(Aircooledtechnology) The wrist pin height is wrong. Its the same as the low compression BUS pistons. If you buy them, you will lower your compression ratio by a point at least. The cylinders are not always round...expect to return a cylinder or two. If you can ask a simple question, "what is the wristpin height?" and you get a valid answer to the question (I never have gotten an answer) And the wrist pin height is the same as the 2.0 liter 914 pistons.... AND Ask if you can return them if your machinist determines that the cylinders are not round... Then go for it. Rich |

the out of round issue seems to be with the BIG bores like 103-105. the 96s are good. as far as pin height....I ALWAYS measure deck and chamber volume to determine compression setting. I have several happy customers that flog the crap out of their AX motors. I have beat on mine for over 3 years

I e-mailed the guy once, and got from him that the parts are AA. I asked about a set for a 78mm crank, and he told me that they could get them. I don't remember if the price was the same... this was right before I found out that my 78mm crank was cracked.

I think I will give it a shot and will make him an offer, I will keep you updated if he accepts and how the kit is.

Sounds like a knock off of the old NPR kits sold 20 years ago. Cylinder walls are thin and out of round. Walk away...

Thanks, Juergen I bought a set a year ago...looks like the same set. Here is a link to the thread with actual pictures. They actually turned out to be pretty nice for the price and true. I never did end-up using them...sold them with the 2ltr motor when I went to the dark side (V8). If I had to do it again, I wouldn't buy them off ebay, but go to a reputable shop that would stand behind them. Who knows but...roll the dice, it's your 2ltr motor. |

Hey Ury,
Don't be dragging my NOS NPR kits down to that level. The 2.0 NPR kits have thick walls, are made of good material, are round, are concentric, and have 8.6: 1 CR..... |

You will get exactly what you pay for.
Just hope you don't need any support, because the guy selling them to you has more than likely never built an engine... |

This is certainly not what I expected down here. Group: Members Posts: 849 Joined: 21-May 09 From: Bodymore Murderland Member No.: 10,389 Region Association: MidAtlantic Region |
I have a hard time buying something like pistons and cylinders on ebay.
Something like a manifold that is cast and heavily produced? Sure...... Something as finnicky as pistons or cylinders? Hell fucking no. You guys probably have not seen what E-bay turbos have done to many motors around since the 914 community is small and isolated, and we will use the term "Traditional" instead of some other ones I can think of. Can you say compressor chunks inhaled by motor? THe carnage looks very cool. |

No experience with those cylinders other than I have a set of them ( 103mm ) on the bench. They measure out fine and the coating seems pretty even. Haven't used them yet.
