Duffy's 1/71 Series 1 240z build

[duffymahoney]

Ordered the fujitsubo exhaust system and the White head performance stainless adapter to my stock manifold.  Not to get it all nicely purge tig welded and get the stupid exhaust studs off.  

[duffymahoney]

Well I broke my exhaust manifold trying to remove a stud.  So I think it's time for a header.  Might as well match my fujitsubo exhaust.  Darn.  I wasn't ready for this decision.  But might as well zinc the rest of the engine bay.

That exhaust looks really clean, is it the revision that came out recently?

Yes it is.  I should have it mostly hung this weekend.  

[duffymahoney]

Working on hanging it.  So far so good.  Hopefully getting the header back from ceramic coating friday.

Worked on the valve cover over the weekend and also took the rest of the engine bay off for zinc.  

Got a new NOS ballast for my ignition and also upgraded to electronic pertronix coil and points.  1.5ohm coil so hopefully my tach works.  

Valve cover is wrinkle powder coated black.  I love how it turned out.

I got the newer type spray bar back from being sonic cleaned and got the valve cover installed. Wow I love the black and zinc look. 

 

This is Prismatic powder coating PWS 4344 Splatter Black

Nice. I'm not a fan of most painted valve covers, but I gotta admit... I like that one.

Thanks! I will retain my stock one raw. Then vapor blast one. Then red. See which I like the best.

Do we get to vote?

Love the exhaust...what did it cost all in?

[duffymahoney]

Well got a ton done and really drove it!

I removed the dealer AC unit.  I will be modifying a  aluminum 280zx mount to use a sanden pump later on.  My giant ac pump makes it impossible to get to so many things.  It had to go.  

New fujitsubo (just came out) exhaust is in.  Sounds great.  My motor is bone stock, so it doesn't sound super beefy, below 2-3k rpms it almost sounds like any other car.  But get on it and it opens up.  I will try to post a sound clip soon.

I was able to use my extra series 1 heat shield, just a few bends and it fits great.  The ztheraphy carbs were easy to install and tune.  My old ones are all gummed up and I couldn't adjust mixture.  My flow meter died, so I still would like to re-tune and mess with timing more. 

My biggest issue came when I went to start it.  I didn't mark on my old dist cap which was #1.  Installed wires on the cap in stock location and nothing happened, it wouldn't try, etc....  I had so many new things new so I started with the carbs.  Checked fuel, checked, ignition wiring (petronixs 1.5ohm coil, nos ballast and electronic points).  Still nothing.  I then found TDC and low and behold my dizzy is 2 cylinders off speared into the oil pump.  Moved wires (#1 is where 4 should be now) and it fired right up! So now at some point I need to pull the oil pump and fix.  

 

First time really driving it.  Some harder pulls, some turns etc..  Even stock motor it's a blast to drive.  Sort of scary, lots of road noise, but it was awesome!  Not a lot of gas fumes, smells, which i am happy about.  Engine bay puts off a ton of heat even with the ceramic coating on the header.  

 

Next is Sanden pump install, along with a new dryer, lines and evap.  Also I am binding mass loaded vinyl to the bottom of my new carpets for some sound damping.  

 

Oil pressure is reading low, I really hope it's the sending unit.  Motor has good compression (I need to re test, I got a new gauge) and doesn't burn any oil I can see.
