Re: SU factory airbox types

[Rob P]

Thanks Rick, Mal  and Matthew. I like SU's and rebuilt some round-top Hitachis 7 years ago. It cost $150 in parts from Nissan (NLA) but they have been working perfectly ever since. I ended up getting an air-flow meter to synchronise them and that makes a hell of a difference, especially noticeable at idle. The car used to shake when idling until I adjusted them, now it is very smooth all through the rev range. I could never get them right before just by listening to the induction noise with a peice of tubing, like they say in the workshop manual. I think this is why alot of people give up on SU's.   Rob P ----- Original Message ----- From: rclough To: [EMAIL PROTECTED] Sent: Tuesday, July 06, 2004 8:20 PM Subject: Re: SU factory airbox types Rob All of your info is correct.   One more bit of info is that "round top" SU's were also fitted to the early "aussi devered" 180BSSS (1972/3).  The square tops came in 1974 when the anti polution regs started to come in. In Japan they had EFI by this time.  For the round top SU's, you have to remove and check the needle numbers to varify whether they are for a 1600SSS or an 1800SSS.  Wont make a lot of difference if you fit the a pair to the wrong engine, but dont mix one of each together on the same manifold.   The smaller, bluey green, symetrical looking air box is the 1600SSS. The bigger air filter box is the 180BSSS - these are orange, but I vaguely recollect later ones (mid 75) went back to light blue/green like  the 1600 one.  It has more hose connections for recycling engine breathers into the inlet air and is not as symetrical in its intake tube area, which has a higher positioned and square shaped intake hole.  ----- Original Message ----- From: Rob P To: [EMAIL PROTECTED] Sent: Tuesday, July 06, 2004 2:16 PM Subject: SU factory airbox types Hi all, I have a few sets of twin SU's, manifolds and airboxes. Datsun factory air boxes (ie air filter housing) come in either orange or a blue/green (teal?) colour. SU carbies have either "round tops' or "square tops". Can anyone tell me what colour box came off what car? I think Rick White has the blue/green airbox on his 510 SSS and that the orange boxes came off the 610 SSS (180B SSS) and that the 610 SSS also had the "square top" carbies. Is that right?   Cheers, Rob P --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]/ --------------------------------------------------------------------- --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]/ --------------------------------------------------------------------- --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]/ ---------------------------------------------------------------------
