siteunseen Posted March 4, 2014 Share #13 Posted March 4, 2014 How old is your radiator? You'll have to remove it, might as well get a new one. Link to comment Share on other sites More sharing options...
madkaw Posted March 4, 2014 Share #14 Posted March 4, 2014 Smart guy to keep it a rolling project. Too many Z's don't get finished because the project drags out too long without any fun driving time. Keeping stock brakes in good repair should suffice.I don't think a "new' radiator is needed but taking it to a radiator shop to be flushed and pressure checked would be smart. Especially a 3 core datsun radiator flow REALLY well and will keep that motor cool.Kind of curious if Rebello specifies oil to use or oil with zinc or any othe additives?Hell yeah ENGINE PORN!! Stock ehaust? Link to comment Share on other sites More sharing options...
conedodger Posted March 4, 2014 Share #15 Posted March 4, 2014 Nice! Though I'm going to slow your project down by bringing mine down there and paying him cash! 8-) Link to comment Share on other sites More sharing options...
Kurbycar32 Posted March 4, 2014 Author Share #16 Posted March 4, 2014 Condodger: I offered him cash! Dave didn't seem to care one way or the other which is weird considering transaction fees. 2% of $$$$ is $$The car has a stainless system in it now thats in good shape. I do have a header thats getting put in thereDave mentioned that even with the new oils lacking zinc the motors hold up fine but that wasnt exactly a recommendation one way or the other.The Radiator is factory. When bringing the car back to life I flushed the radiator myself then painted all of the non-grill area. It passed pressure tests and keeps my poorly running motor cool now. Radiator upgrade is part of my AC conversion so its definitely on the list.I am considering changing out the fuel pump with one of those carter rotary pumps, then eliminating the pump in the engine compartment. With that would come some stainless braided fuel hoses and maybe some kind of fancy fuel rail. Link to comment Share on other sites More sharing options...
z boy mn Posted March 4, 2014 Share #17 Posted March 4, 2014 I did the Carter fuel pump last summer and am happy with it. It supplies plenty of fuel for my triples and holds steady at around 3-5 PSI, so no need for a regulator (for me, anyway). It is on the loud side, even with the vibration mounts, but that just lets me know it's running. The only issue I had was getting recommendations on the return line. Most folks (including Top Performance) said it didn't need a return, but I kept hearing the pump dead head. I called the manufacturer and they were horrified (they said it needs fuel running through it to cool it), so I put in a return line. Bad sounds went away and it runs like a champ. I'm still not 100% sure if it needs one or not, but it seems happier this way.Also, I like your "rolling upgrades" option. I got my Z from someone who did everything at once, and 16 years later it wasn't up and running yet. In the end, we put it together together and he got to drive it 8 miles before I drove off with it. I need to go pay him a visit now that it's running well and let him scream around the block a few times!Good luck with the new motor, sounds like a fabulous way to celebrate spring!

Zedyone_kenobi Posted March 4, 2014 Share #18 Posted March 4, 2014 Look into the Mallory fuel pump on summit or jegs. It is internally regulated at around 3 psi and is VERY quiet. Link to comment Share on other sites More sharing options...
tlorber Posted March 4, 2014 Share #19 Posted March 4, 2014 I say go with a 5 speed while you have the motor out. Then a 3.7-3.9 rear diff. Link to comment Share on other sites More sharing options...
Kurbycar32 Posted March 4, 2014 Author Share #20 Posted March 4, 2014 Thinking about clutches: The upper limit of theoretical power for this car is about 300hp, will a stock clutch system handle that or do I need something like a centerforce? Zboy: The tip on the return line is great, thanks for that. Zedyone: I checked out the mallory pump, thats a $300 unit. I have a 5 speed manual Link to comment Share on other sites More sharing options...
jonathanrussell Posted March 5, 2014 Share #21 Posted March 5, 2014 I hear what you are saying about not pulling too much apart. You might consider this though if you haven't already...In addition to cleaning up / painting the engine bay while the engine is out, I like to take the opportunity to remove and powder coat the cross member and rebuild / powder coat the steering rack.

RIP260Z Posted March 5, 2014 Share #22 Posted March 5, 2014 Kurbycar,And enjoy it when you get the engine up and running (I do with my Rebello 3.2l unit).... clutches, also may want to look at ACT. Fuel pump, there is also Holley. Link to comment Share on other sites More sharing options...
