Stuey, Minor modes required to shoehorn a L20B/5 spd into a 1600
Engine: use 1600 engine mounts, brackets, sump & oil pickup. You usually need to modify the exhaust (L20B ports are ~3/8" higher that L16/L18), move the throttle linkage on the firewall for the same reason (if solid bar being used, cable should be OK) and also possibly a 9" type i.e. thinner air filter if you're using stock L20B downdraft carbie, as some L20B stock filters hit the 1600 bonnet. Minor electrical changes if you're changing over from stock 1600 alternator eg Lucas or Hitachi externally regulated to L20B Bosch internally regulated - most 1600 have already been converted but not all. Heater hoses of the 1600 are sometimes required, again depends on what the L20B is out of, Bluebirds use a water tap near the starter in the long side hose, 1600 have tap inside the car. Gearbox: modify gearbox xmember (varies depending on what the 5 spd is out of - i.e. long box, stumpy or dogleg), assuming long box you need 955mm tailshaft (stock 1600 is 1090mm), flat type rear engine mount eg 240K, C210 or Stanza (can't recall whether 200B fit), longer speedo cable eg 180B auto or 620, if you want to use the 1600 adjustable clutch release bar you have to change it over in the bell housing, make sure that you use the release bearing that goes with the clutch being used (different length i.e. shorter is used on 1600 to most other Datsun clutches), if you want to use the auto adjusting clutch release rod off the 5 spd box, then just bolt the 1600 slave cylinder up the 5 speed and bleed it - it's that easy. Some 5 spd boxes will need a small adjustment to the hole in the tranny tunnel, easy to do but you are supposed to re-enforce the tunnel for rego purposes, and watch out for the rear brake line as it runs right under the top of the tranny tunnel, cut it and you'll not be happy. That's about it, long time since I've done this personally so I'm sure to have missed something that someone else will pick me up on. Have fun with it, regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Stuey Roberts Sent: Sunday, 9 February 2003 4:04 PM To: [EMAIL PROTECTED] Subject: Gearboxs, 4spd Vs 5spd hey listers, i am about to purchase an immaculate 1600 that has the original 4spd behind an L16.what i am going to do, is once i get it, i am putting my L20B with a 5 spd box into it, What i am wondering is if there are any changes, mods that i have to do, like different shorter tailshaft, and will i have to cut another hole in the tranny tunnel for the gear stick??? i am guessing that the 4spd is shorter in length that the 5spd, or are they the same???
