kiwi303 Posted May 22, 2008 Share Posted May 22, 2008 Anyone here recognise these? They came in the miscellaneous bits boxes I got with my new '78 fairlady project car. The car has already had the motor stripped out and the exhaust system looks to be fabbed up for a V8 or V6 twin pipe setup there's an arrow that curls back on itself moulded into the boxy part of it, which makes me suspect turbo intakes maybe? Are these off a Nissan V6 anyone can recognise? or another manufacturers V6? Anyone know the maker that uses a curled arrow as a logo? cheers Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted May 22, 2008 Share Posted May 22, 2008 Marine exhaust manifolds possibly? Quote Link to comment Share on other sites More sharing options...
evildky Posted May 23, 2008 Share Posted May 23, 2008 yeah looks like marine manifolds, doesn't resemble any nissan V6 I've ever seen Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted May 23, 2008 Share Posted May 23, 2008 Marine manifolds are almost always watercooled, is there evidence of an inlet/outlet for water? Pretty cool looking, but I doubt cast aluminum would be used for exhaust. Seems like an intake setup. Quote Link to comment Share on other sites More sharing options...
kiwi303 Posted May 23, 2008 Author Share Posted May 23, 2008 While I was out the back of the farm at the hayshed i've got the Z in now (3 km from the house down the back of a valley not nearly as convenient as the shed by the house ) looking over the trim panels and gearbox I had a look at the pipes as well. I was thinking as bulky as they were, and being Ali, that they would be intake plenums of some description, and as coming with a Z car, possibly nissan. Anyhow a closer look shows soot inside, and the small pipes to the left of the pic go to a square jacket around the actual exhaust pipes. looking in the open ends at the right of the pic shows a gap between the inner pipe and a jacket down the curved pipes, it looks likely that the exhaust pipes continue to be sleeved with a water jacket further. with the volume of water that looks to use, the probably are marine, and made of ali to stop saltwater corrosion. Thanks for your help guys, now I just need to work out what to sell them as, or if just to take them to a scrap dealer for the ali value. 5c might be enough Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted May 24, 2008 Share Posted May 24, 2008 Well, I would assume they are a somewhat common part so you may ask a marina. Quote Link to comment Share on other sites More sharing options...
kiwi303 Posted May 25, 2008 Author Share Posted May 25, 2008 Well, they turn out to be made by Hamilton Jet, http://www.hamiltonjet.co.nz so I've sent off an email to see what they say The mystery is almost solved Hopefully I'll be able to flog them off somewhere else to a jet boater or boatbuilder, if not back to the factory to become factory refurbished parts they then sell on again All the more cash to pour into the Z Quote Link to comment Share on other sites More sharing options...

Water inlet is those two hose barbs on the ends while water outlet is the exhaust outlet itself. Quote Link to comment Share on other sites More sharing options...
