Re: 180hp L18 rally motor! Is it possible? Cheap!

[Nicholas Abraham]

Geez, $12000 for a L18.   Out of interest, where does the money go?   My list of the main mechanical mods required would be something like......   BOTTOM END   L16 rods and shaved (Flat top) L18 pistons. Decked block - gives +0.3mm at TDC. Fully balanced, polished, and shotpeened rods. Balanced and polished crank. Tidy up block Heavy duty bearings Lightened and balanced 6 cylinder flywheel and clutch.   HEAD Bluebird head with welded in 'squish' areas. Major exhaust port modification. Minor modification/tidy up and port-matching of inlet port, perhaps raise it slightly. 5 angle valve job CC combustion chambers Machine head to give ? compression. Do you want to run Regular or Premium or AVGAS?   ACCESSORIES Cam/Valve springs ? Depends on performance required. Carburation - WEBERS!!! or EFI Extractors ...... Hmmm.....   As long as you don't want to run over 7500rpm I don't see why it should cost heaps. Of course there are the long hours needed to prepare and measure everything.   Nick 1978 Datsun Stanza   --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
