drunkenmaster Posted November 19, 2008 Share Posted November 19, 2008 Hi Guys, 2 quick questions for you all: 1) I have a S2 RB25DET in my 260Z, however the heater water lines from the RB are larger diameter than the fittings protruding through the firewall from the 260Z heater. How are people reducing the water lines or increasing the 260Z hard fittings to match? 2) The RB carbon cannister is on the exhaust side of the engine and 260Z lines to the tank are on the intake side (i.e. opposite), how have people routed the lines/mounted the cannister to suit this? Thanks Quote Link to comment Share on other sites More sharing options...
tonycharger72 Posted November 19, 2008 Share Posted November 19, 2008 1) I have a S2 RB25DET in my 260Z, however the heater water lines from the RB are larger diameter than the fittings protruding through the firewall from the 260Z heater. How are people reducing the water lines or increasing the 260Z hard fittings to match? Thats weird - my RB30 lines were the same as the Datsun heater lines! Have you stuck some calipers on them? what is the difference in circumference? 2) The RB carbon cannister is on the exhaust side of the engine and 260Z lines to the tank are on the intake side (i.e. opposite), how have people routed the lines/mounted the cannister to suit this? Throw it away , My car is a 74 and pre-pollution and In the ACT my car has to conform the pollution & noise standards of the date of production of the vehicle, in NSW its the engine, is that the case in VIC? - Pretty sweet, I have to conform to 1974 pollution and noise standards!!! I don't need cats, carbon cannister and apparently the exhaust note can hit 98 decebls !!! Quote Link to comment Share on other sites More sharing options...
drunkenmaster Posted November 20, 2008 Author Share Posted November 20, 2008 Thats the second time someone has told me the heater lines mated up on theirs. I will get some measurements/photos. As for the cannister, my car is a post-emmisions '77 Quote Link to comment Share on other sites More sharing options...
Mike Rowe Posted November 20, 2008 Share Posted November 20, 2008 In WA you have to meet the standards associated with the engine not the vehicle year unfortunately. Quote Link to comment Share on other sites More sharing options...
Canadianz Posted November 20, 2008 Share Posted November 20, 2008 Hey Mike, our heater core hooked up just fine. Maybe you have a different unit ? I have a series two Rb in a first gen 240z. Yeah don't worry about the carbon canister. Quote Link to comment Share on other sites More sharing options...
Careless Posted November 20, 2008 Share Posted November 20, 2008 if you're having trouble with the heater lines, you could get some brass reduction double barbs. they are 3/4 on one side and 5/8ths on the other, as well as various other combinations. get some fuel injection #8 clamps, and it should be good for both ends. you could get some fuel injection #6 or #4 size clamps but they are so close, and the #8's can go down to the size of a #4 as far as I recall.

drunkenmaster Posted March 31, 2010 Author Share Posted March 31, 2010 I know it's been years, but I finally have time to get back on with the Z and am keen to know why my heater pipes don't mate up like everyone elses! Heres the long promised photo, you can see the RB25DET pipes fit too loosely over the Z inlet/outlet. Thanks Quote Link to comment Share on other sites More sharing options...
RS Speed Posted April 1, 2010 Share Posted April 1, 2010 (edited) throw on a hose clamp and tighten her up, it's not gonna leak. Edited April 1, 2010 by RS Speed Quote Link to comment Share on other sites More sharing options...
