Got it installed. Here is my overall quick review. It's pretty quiet 800-1600 rpms. Almost weirdly quite. I have a bone stock 2.4L so that has something to do with it. Above 3k rpms it starts to sound like a z. But not really throaty. Again that is probably from being a bone stock motor. I will try to take a video and post it. I was hoping for more of the sound people have in videos, but I guess I have no idea what rpm that is at when the rev.

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.

My exhaust says it's " It is only compatible with safety standard conformity product 2 seater exclusive Super EX (510-15037) It is incompatible with original EX Mani and Super EX (510-15036) So I am guessing the only option is 510-1535 and 510-15307. Looks like the 510-1535 is equal length header. Which is pretty awesome.

I never thought you were going mad. But we know that this header works and was designed around the new system (510-15037) . I can measure but I don't see a point. It couldn't be higher. I think they maxed out the design to a crazy tolerance for tuck. Fitment looks basically identical to the pictures posted. I will be curious to see how the 510-1535 (ex-mani) fits around the steering and su's. I like the look of the newer header ex-mani more then mine, but it wasn't for sale when I ordered mine (at least what fujitsubo told me). Looks like the changed the tubes a lot. Same size tubes in both headers. I would be curious why. Probably some sort of flow improvement I would guess. I also don't see it listed on their site yet (which isn't easy to navigate), I am willing to bet it launches fully June 1st. When the backorder will be done.

Fitment is awesome. I can’t believe how well it tucks. The header must be correct or at least made for the newer system. Its on and mostly tight. I might tweak it a tiny bit. The exhaust tips are ever so slightly off angle and one more exhaust hanger and it’s done. I tried working from the back forward. Which didn’t work. Then I tried middle forward which didn’t work. Engine back worked great. I love learning from mistakes.

Do you have it?

Maybe that’s only rhd? Who knows. But this is the header they are selling for the system now. They are back ordered till June. Maybe they will do the upgraded header then? I hope it works

Maybe they changed the design after the article? Who knows until I try and bolt it up. So current offerings for headers is 510-15035 and 510-15037 . The exhaust says it only bolts to 510-15037, which is what I have, which matches pictures if you google 510-15037. So again fingers crossed:)

It's not, looks virtually identical. Old is 510-15036

Quote from their webpage: It is only compatible with safety standard conformity product 2 seater exclusive Super EX (510-15037) WHICH IS WHAT I HAVE. Some machining may occur when attaching an old car. In that case the cost and claims etc can not be applied at all.

That might be the header that doesn't work with LHD z's. There were 2 to choose from that bolt to the new exhaust. Again, language barrier, new product, so my fingers are still crossed it bolts up:) I am hopeful though. I did as much due diligence as possible.

It’s not. I had Jesse Streeter communicate directly with Fujitsubo to make sure it works with my exhaust. I’m sure it looks similar if not basically identical to their old system. Doesn't look like the header from page one of this thread though. I guess fingers crossed still:)

Nope, only fits my model exhaust, well fingers crossed:)

New Fujitsubo header is in! Well mostly. It’s coated in chromex ceramic coating inside and out for heat reduction. Clears steering well. Also my series 1 heat shield could be bent up to clear

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

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

He is a great guy, he is rebuilding my 11 mikuni carbs as we type.

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.

It's still going but they don't do anything mikuni anymore. I believe Dave Premo bought up the parts (http://tuning4performance.com/)

I get the header back probably wed from cermanic coating. Then install time!:) Should clear and have around 2" from the steering shaft.

Thanks! That helps. I have the brackets backwards. Do you have the system?

No instructions. Anyone else get the kit?

Sounds good:)

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

I don't believe my bumper rubber is cooked, it's definitely not perfect.
