phildub Member 52 Member For: 18y 1m 22d Posted 19/07/08 01:11 AM Share Posted 19/07/08 01:11 AM I would have think that is if you used Atomic parts your result would either be the same or worse than a complete atomic engine. They will give you the specs to use and the result will be the same. It sounds like you should go and get Autotech Engineering or Nizpro to supply you an engine as they seem to have happy customers or you could repeat what other have done and end up with you money in the bin, sounds like Atomic by name Atomic by nature, boom!!!

Ive got an atomic short motor that has only done 15,000km and was replaced due to sick of noise in a mates car. Was planning on using block,crank and rods and getting a descent set of pistons for my car. Are these pistons you use the goods and can this be done.

Just get your machinist to set them to the spec sheet. They are a pretty tight clearance for a forged piston. There were issues with earlier CP pistons. Dont know about nowIf you do your research properly, dont rush it, have a good machinist and the right tools, you will probably do a better job of most workshops out there who have 15y/o apprentices assembling their engines. But if you are a bit of a cluts then get all the good bits and leave it to the pros for assembly. Link to comment Share on other sites More sharing options...

I though Nizpro designed there own and then get them made, they have never said what they used Link to comment Share on other sites More sharing options...
