Richard, Most late boxes have ** 71C cast on the left side bell housing on the later boxes. Up to 1985 they had NMCA (Nissan Motor company Australia and 71B (eg bluebird series 3). When the 6 bolt C pattern boxes came out mid 80,s the 4 cylinder Pintara's continued with the 71B box and the sixes and turbo model engines had the 71C box with the six bolt shifter housing.
Internally there are three types of gears in the 71C's. The standard closer gear sets with 3.36 first (most common) and standard ratios from 71 B up to 4Th and a 0.865 fifth as used in the R31 SKYLINE. There are some 71C boxes X Z31 300ZX's with the 0.75 5th gear. There are also the R32 RB20 DET boxes with reinforced bell housing. Then there are the RB20 DET R31 GTS-R boxes as described with the 0.75 5th gear, reinforced bell housing, double synchro's on second and third gears and cast iron 3rd & 4th selector instead of aluminium for extra durability. These boxes also have the monster gears suitable for big torque engines. Then you can go to the R30A box (RB25 GTS-T, VL Turbo, GTR and Patrol with RB30)................................

Errol Very interesting to get the story on the L series gearboxes. But I have yet to find one with the model stamped on the box. I take the model details from the Vehicle data plate if I know its matching. How do you tell box model differences from the outside? ----- Original Message ----- From: "E Smith" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, 28 June 2002 9:07 AM Subject: RE: Gearbox woes!!! > RS=column or cable shift selectors > FS=extension housing mounted shift lever > 4/5=number of forward gears > C=close ratios (ie 2.9 and 3.36 first gears) W= wider ratios (3.6, 3.9 4.2 > first gears) > 71 distance between shaft centres > I understand that the A,B, & C are the generation models of the box but open > to correction? > > Cheers > Feral Errol > [EMAIL PROTECTED] > http://www.datrats.com.au/ > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Steve Lamb > Sent: Thursday, 27 June 2002 9:17 PM > To: [EMAIL PROTECTED] > Subject: Re: Gearbox woes!!! > > > > >Hence S130(240Z) FS5W71B (long not dog leg) > > No, 240Z's used 3 types of 5-speed, all close ratio (FS5_C_ not FS5_W_): > > Up to mid' 71 - FS5C71A (same as Roadster but different bell and > extension housings > > From mid '71 to end '71 - FS5C71B, rare flange ouput type > > From end '71 - FS5C71B, sleeve output, also used in 260Z > > The 'A', 'B' or 'C' at the end of the box ID basically indicates the > type of extension housing/shifter arrangement. > > > --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/[email protected]/ ---------------------------------------------------------------------
