Datsun weight and L20B qns.

[abrahamk]

I'm new to the list and this is my first go at a Datsun project car, I've got a few technical questions, the answers may be of assistance to others as well. Here they are, thanks in advance. Nick.    What do the various Datsun models weigh? I am specially interested in the Stanza, 200B, and Bluebird.   How much metal can be ( safely! ) removed from a L20B flywheel?   I need to remove approx. 2mm of metal from the head and/or block to give a ~10:1 CR. The std. combustion chamber volume is 65cc (swept vol. = 488cc), I want to bring it down to ~55cc including the small amount of reprofiling needed around the inlet and exhaust valves. Can it be done, and has anyone done it (or does everyone use the L18 head)? What is the minimum deck clearance allowed ( approx. 10thou??? ) and can the slightly dished pistons be shaved flat and remain reliable to >6000rpm?(See supercharged Bluebird feature car) How much can the head and deck be shaved?   Also, the L20B head appears to have poor 'squish' areas in the combustion chamber, specially considering the dished pistons ???   I am currently re-building a L20B  from a Bluebird TRX donor vehicle for use in a road/club car, I intended to use a Stanza shell to give the best power/weight ratio - but they are (relatively) expensive and hard to find.       --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.datascribe.com.au/ozdatonline/index.htm http://www.datascribe.com.au/ozdatonline/listindex.html ---------------------------------------------------------------------
