Madness. I'm looking forward to seeing this progress! Me too. We just had another 8" snow, but I'm hoping to get to the storage unit tonight to do a bit more. At least shoveling warms you up! I believe I now have everything required for fitting the ITBs. The last part was figuring out the fuelling - I could just try and reuse the stock fuel pressure regulator, but it isn't adjustable, and if I need more fuel pressure, I'd have to upgrade anyway... so I've got an Aeromotive 30 - 70 PSI unit which will accept my fuel pressure gauge. Another issue is getting rid of the charcoal canister - I did this on my NA MX5 without thinking, but in the 280Z it's a bit more of a contentious subject. The fuel tank has a vent that runs under the car, into the charcoal canister (bottom right of this image):  This is quite important for relieving pressure from the tank, especially on long drives. The vapour travels through the line from the tank, and is captured in the charcoal canister. On top of the canister, is a pressure operated valve that takes a vacuum line from the inlet manifold, and another hose that vents the vapour into the throttle body. When the car is running, the valve opens, and the vapour is burned by the normal engine operation. Wonderful. However, converting to ITBs, there's no logical place for this to go. The car absolutely stinks of fuel after a long run anyway, so I'm fairly sure something in the system leaks. So I've ordered one of these:  A remote fuel tank vent, with a roll over valve. It needs to be mounted the same height or higher than the fuel filler, so I'll start looking for a suitable spot next time I'm under the car. I also picked up a new tool chest for $99 on clearance, which is going to hopefully tidy up my working area a lot (lol jokes, I'm just going to fill it with more tools). |

280Z ITBs - PartsI hadn't really planned on doing this for the 280Z, it was more of just a long term dream. But then the exchange rate was good, so I pulled the trigger on some ITBs from Japan:  The kit came with everything you could possibly need - including this nifty vacuum block:   The quality of the ITBs is excellent, I can't wait to get these on the car.   One key component that's not included is the fuel injectors. I picked up some second hand RX8 injectors, which should give me plenty of fuel flow:  I had the injectors cleaned and flow tested, all six of them getting a clean bill of health with matching flow rates. It's still regularly snowing in Minneapolis, so anything I can do indoors is welcomed right now. With that in mind, I spent a pleasant Sunday morning fitting up the fuel rail and injectors.  Next up was changing the TPS connector over for a plug that matches the rear of the wiring loom:  Bottom is the TPS adapter for the GM unit I won't be using, top is the ITB TPS.  Finally, I looked at figuring out the fueling situation. The FPR on the car right now isn't going to cut it, as it's hard to relocate (plus it's ancient). So I've picked up a Aeromotive unit that will give me 30 - 70 PSI:  Fitted up the fuel fixtures using Permatex No. 3:  And the plan for the fuel system looks like this:

that kit is a work of art. that vac block for instance. looks so appropriate next to the itbs. with the combination of brass and silver metal, it's nearly a sort of steampunk look, and then they have quick connect fittings. so funky.

Yeah, for sure. It's getting hard to find things that are going to look sympathetic in the engine bay now. Unfortunately the vacuum hoses it came with are bright red, so I'm trying to find a suitable black replacement. |

Hubba hubba, can only echo Alex's sentiments. Would love to get something like that for my ITBs.

I don't exactly know what I'm looking at, but I know it is very good.
Not jealous at all of this...!

Hubba hubba, can only echo Alex's sentiments. Would love to get something like that for my ITBs. There's a ton of universal vacuum blocks available, but this is the first I've seen using push fittings. I had a garish purple one on my old MX5... The weird thing with the OER ITBs there's a set of push fittings on the manifold, and then vacuum barbs on the ITBs themselves. My plan is to use vacuum block to run the brake booster, fuel pressure regulator and the MAP sensor, and the barbs will hook up to an idle control valve. |

Hope you're all enjoying spring - we're in the middle of a two day storm that's dumped at least 12" snow on already icy roads. Even for Minnesota, this is unusual for April. Beginning to get a little stir crazy! Good news on the garage front - my buddy that lent me his space when I first bought the car has just had an offer accepted on a new (epic) house. I'll post some pictures once he's moved in, but the key feature of interest here is that is has two double garages - one built in to the house, and one separate. After some complex negotiations involving beer, plans and far too much generosity, I'll be renting the separate double as soon as he gets the keys. Moving from a unheated, no power storage unit to a heated, and hooked up garage that's twice the size is going to be awesome. Hopefully I'll even be able to drive the 280Z there instead of having it towed...   |

There's now a list, warmer weather and a whole Saturday to do some damage.  |

As my last picture of a picture eluded to, the ITBs are now on the car. Now I need to figure out where to route vac lines and the like.  The red box in the diagram is where I think the vacuum block will fit best. Ideally I'd like to have it exactly where the brake master servo is, but that doesn't look likely. I guess that's what you get for having a kit for a RHD car  Some luck though, the FPR actually bolts straight into the bracket where the charcoal canister was, and the return line is already there - so all I have to do is put the outlet line from the fuel rail round the back of the engine to the FPR. The throttle linkage all connected up, and I stuck my foot on the loud pedal a couple of times and made car noises in my head. Getting there slowly... |
