Kennyt Posted September 27, 2015 Report Share Posted September 27, 2015 Is egr valve needed with this setup? Can i remove the pipe and egr from exhaust manifold to egr? Id so what is used to plug the manifold and egr port? 1 Quote Link to comment
Lockleaf Posted September 27, 2015 Report Share Posted September 27, 2015 I run my z24 without the emissions stuff. On the intake manifold, make or buy a block off plate that covers the opening. Use the egr bolts and gasket to seal it. On the exhaust, I cut the egr pipe off, leaving about an inch hanging out of the exhaust. Then I stuck a bolt in that and welded it closed. This isn't necessary to run a Weber. In fact a good condition egr can improve gas mileage, but you can run without it and overall engine performance will not suffer. 1 Quote Link to comment
datzenmike Posted September 27, 2015 Report Share Posted September 27, 2015 The above. You can also remove the pipe from the exhaust manifold and replace with a metric thread pipe plug. No welder needed. The easiest thing is to just leave it alone and pull the hose off the EGR valve to deactivate it. Depends what you want. 1 Quote Link to comment

Kennyt Posted September 28, 2015 Author Report Share Posted September 28, 2015 I was trying to clean up all the unnecessary piping. Had to replace a head gasket and that pipe is aggravating to get off and on to remove the head. 1 Quote Link to comment
Lockleaf Posted September 28, 2015 Report Share Posted September 28, 2015 I hate removing the damn things as well. Once you get one free though you can slather it with high temp anti-sieze and the next time it should come off without the ridiculous fight. Do as you will, but that's another option. 1 Quote Link to comment
datzenmike Posted September 28, 2015 Report Share Posted September 28, 2015 Actually none of it is unnecessary and all are there for a reason. But they are a pain. 1 Quote Link to comment
living_4kicks Posted October 12, 2015 Report Share Posted October 12, 2015 I am going to put a Weber on my truck. Just wondering if you all could give me a heads up on kind of hiccups I can look forward too. I have worked on a couple edelbrock carbs in old Chevys and that's about it. 1 Quote Link to comment
datzenmike Posted October 12, 2015 Report Share Posted October 12, 2015 Get a direct replacement from Redline. Has everything needed... gaskets, adaptor, bolts, air filter. And it's not worn out and not been rebuilt 5 times and missing parts. 2 Quote Link to comment
DrvnDrvr Posted October 13, 2015 Report Share Posted October 13, 2015 Research the difference between the 38 and 34/36. I have a 38, love it, but it does suck on MPGs 1 Quote Link to comment
Charlie69 Posted October 17, 2015 Report Share Posted October 17, 2015 In Phoenix I have to emission test my 1986 720 every 2 years so I have the EGR valve intact. The emission test person always pulls the EGR vacuum hose off to check for vacuum. 3 Quote Link to comment
Jester Posted December 25, 2015 Report Share Posted December 25, 2015 I'm with Mike on this one. Spend the money on new one. By the time you try to get on older one working good, you may as well have just started new and been 10X happier. 1 Quote Link to comment
Charlie69 Posted December 25, 2015 Report Share Posted December 25, 2015 I purchase all my Webers and parts from Pierce Manifolds Inc I have been doing business with them for decades. They know Datsuns. http://www.piercemanifolds.com/ 2 Quote Link to comment
Draker Posted December 25, 2015 Report Share Posted December 25, 2015 I've got a used 32/36 on my L20. I've rebuilt it twice... It works, but it's far from perfect. I would also recommend new. 1 Quote Link to comment
Charlie69 Posted December 27, 2015 Report Share Posted December 27, 2015 I put a new Weber 32/36 on my 86 720 when I bought it over 5 years ago in Battle Mountain Nevada that I ordered from Pierce Manifolds. Still running great! 1 Quote Link to comment
Slick68 Posted January 14, 2016 Report Share Posted January 14, 2016 How much does one of these kits cost? I can't seem to find pricing on the Redline webpage, and can't find the kit for my 86 Z24 on the Pierce Manifolds page. 1 Quote Link to comment
Rhino13 Posted January 14, 2016 Report Share Posted January 14, 2016 How much does one of these kits cost? I can't seem to find pricing on the Redline webpage, and can't find the kit for my 86 Z24 on the Pierce Manifolds page. ~$300 with the adapter plate, list it as any year between 83-85, the 86 was switching to efi so some places assume it's on every 86. 1 Quote Link to comment
datzenmike Posted January 14, 2016 Report Share Posted January 14, 2016 How many wing nuts hold the air filter on???? 1 Quote Link to comment
Slick68 Posted January 14, 2016 Report Share Posted January 14, 2016 I don't know. The truck doesn't have an air cleaner with it, and the stud is gone, too. 1 Quote Link to comment
datzenmike Posted January 14, 2016 Report Share Posted January 14, 2016 I thought all '86s had the EFI throttle body injection 1 Quote Link to comment
Charlie69 Posted January 14, 2016 Report Share Posted January 14, 2016 The 720 Z24s are rare with the TBI. I have only seen a few and they were all 1985 4x4? 1 Quote Link to comment
Charlie69 Posted January 14, 2016 Report Share Posted January 14, 2016 Call Pierce manifolds great people to deal with. Mike Pierce explains the Weber and gives some good info in the following Videos. They know Datsuns/Nissans. By the way these are old videos and prices have gone up over the years. 1 Quote Link to comment
DATSAN Posted January 21, 2016 Report Share Posted January 21, 2016 Are you sure that's not an '83 or '84? That engine is exactly like mine. There is only one wingnut that holds on the original air cleaner, and two nuts that bolt (via a bracket on the side of the air cleaner) to the valve cover. This is a very old pic from my '83 720 Z24 before replacing it with a weber. 1 Quote Link to comment
DATSAN Posted January 21, 2016 Report Share Posted January 21, 2016 Well, I see the heater core is gone. I hope you live in one of them thar warmer Tennessee climates. Here is my Engine, a spitting image of yours, all cleaned up - pre-weber era; 2 Quote Link to comment
datzenmike Posted January 21, 2016 Report Share Posted January 21, 2016 The 720 Z24s are rare with the TBI. I have only seen a few and they were all 1985 4x4? The Z24i with TBI was from April, '85 on so just a couple of months at the end of '85 and June to October '85 or 5 months into the '86 model year. This was the changeover to the D-21 Hardbody and the end of the number trucks. The first Hardbodys were November '85. 1 Quote Link to comment
