Josh K. Posted June 9, 2015 Author Report Share Posted June 9, 2015 Got the hardware to mount the water pump. All done. Clears now ;) Belt all tight and ready to go.... MAP Sensor/Boost gauge "Vacuum block" and bulkhead power pass through mounted. Discovered that panel has a bit of bondo.... Made my drill bit walk and the Vacuum block holes are kinda ugly. Gonna make a plate to bolt over.. 4 Quote Link to comment
datsunfreak Posted June 9, 2015 Report Share Posted June 9, 2015 What are those bolts called? Those would be cool to use on the whole engine... :thumbup: Got the hardware to mount the water pump. All done. Quote Link to comment

Josh K. Posted June 9, 2015 Author Report Share Posted June 9, 2015 No stainless in aluminium!!! Hell... no stainless fasteners if at all possible!!! 1 Quote Link to comment
Mattndew76 Posted June 9, 2015 Report Share Posted June 9, 2015 Stainless is no bueno for aluminum threads. Heck 12.9's are far superior for strength. Stainless just looks purdy. Quote Link to comment
Josh K. Posted June 9, 2015 Author Report Share Posted June 9, 2015 Yup. Way too soft. Only use when you absolutely have to. Gets gummy coming out and then your done.... Quote Link to comment
q-tip Posted June 9, 2015 Report Share Posted June 9, 2015 I said looks like, I know stainless and aluminum don't get along thread to fastener wise, geez.... Quote Link to comment

Niz16 Posted June 9, 2015 Report Share Posted June 9, 2015 Looks like I'm removing some stainless bolts I just bolted my water pump on with when I get the car back from the paint shop, I've got lots to learn , and don't mind admitting when I'm wrong, cheers guys that just saved me some trouble in the future hey, Cheers guys :) Quote Link to comment
Niz16 Posted June 9, 2015 Report Share Posted June 9, 2015 So no stainless if at all possible? But stainless bolt n nut combos ( being used together are ok?) Quote Link to comment
q-tip Posted June 9, 2015 Report Share Posted June 9, 2015 I forgot to add the laughter at the end of my post. :lol: Quote Link to comment
Josh K. Posted June 9, 2015 Author Report Share Posted June 9, 2015 So no stainless if at all possible? But stainless bolt n nut combos ( being used together are ok?) I don't really have issues with them together. Just use anti seize.... 1 Quote Link to comment
Josh K. Posted June 9, 2015 Author Report Share Posted June 9, 2015 Stainless steel fasteners are particularly susceptible to thread galling, although it also occurs in other alloys that self-generate an oxide surface film, such as aluminum and titanium. During the tightening of the fastener, pressure builds between the contacting thread surfaces and breaks down the protective oxide coatings. With the absence of the oxide coating, the metal high points of the threads are exposed to one another, which increases friction. The combination of these two events can generate enough heat to fuse and seize the nut and bolt together. Quote Link to comment
tr8er Posted June 9, 2015 Report Share Posted June 9, 2015 Josh, this build is one of the best motivators currently on this site. Thank you for keeping true to the real purpose of this site as I see it, and keeping it valid. There are a few others, myself not included. But I intend to return to work as soon as my work-space is cleared out from moving. Dissimilar metals and corrosion is a Huge part of my job. Crazy how critical this consideration is, yet it is hard to accept at times that using a corrosion resistant metal, can actually promote corrosion in its vicinity. Electric potential is a bitch.

datsunfreak Posted June 10, 2015 Report Share Posted June 10, 2015 That says zinc and iron are no good together? Wouldn't that mean the factory screwed up on a lot of the engine bolts? Would explain why the timing cover bolts break so often coming out... 3 Quote Link to comment

Thank you very much. I've really enjoyed building this car and all the little challenges and enjoyed sharing it with you guys just as much. The journey has been fun but the first time I release that clutch is gonna be something else :) I've been so focused on all the little details that I forget what the big picture looks like. Now its all coming together and it's pretty cool ;) Thanks again. 2 Quote Link to comment
Niz16 Posted June 10, 2015 Report Share Posted June 10, 2015 Cheers for the help and info guys very much appreciated ( sorry Josh I was not meaning to hijack your thread bro) Can't wait too see the next instalment of progress pics by the way too!!! It's going to be sweet just too see it all in the same shade of undercoat! Quote Link to comment
Icehouse Posted June 10, 2015 Report Share Posted June 10, 2015 What a hole page with no crazy build pictures.... I feel ripped off :) 3 Quote Link to comment
