New ECUI have long terms plans for keeping this car, so maintenance, cost and availability of parts is always a concern. Thankfully, there's a solution - enter the FAST EFI kit. This replaces all the sensors in the engine bay with newer, cheaper, and readily available (as in walk in to Autozone and buy a replacement that day) GM parts. The rest of this post isn't going to be very interesting, as it's more for my reference later on if I need to buy anything. The nice thing about this kit is it comes with all adapters you need to hook straight up to the L28 engine, which is a huge convenience. First up, coolant sensor and thread adapter:    TPS sensor, adapter and wiring loom adapter:      MAP Sensor:  Idle valve and K&N filter:     And a couple of elbow joints with barbs for routing this to a vacuum point:  Air intake temperature sensor:  The MAF is deleted - there's a nice aluminium pipe for that:  A load of vacuum points will also be blocked off, as all the cold start stuff comes off as well:  Fully labelled loom (yes, all the sensor wiring is also replaced throughout the car):  Wiring for the touchscreen:  RPM Converter:  Spare wiring conduit to tidy everything up - I really appreciate small touches like this:  O2 sensor - if anyone knows the part number for this, I'd appreciate it!    The ECU and touchscreen display:  And finally, the first thing I can actually tackle... the O2 bung:  Next up will be removing the exhaust manifold to have the O2 sensor bung welded in.

They look awesome mate! Isn't there an app that can translate text? You just open your camera and it translates it for you. I've heard of it, might be worth a shot.

I'd want those mounted on the wall. BEAUTY!

Hopefully I can find something like that. I didn't actually get a good look at the instructions, but there are plenty of diagrams at least! Edit - Google's Translate app for Android will take in an image and spew out the translation. Nice! It even worked on my crappy mobile phone pic, will scan the instructions and run them through it to hopefully get something workable. |

Those mesh strainers are meant to be OK :-)
I think the airbox sausage style gives the best performance and filtration tho.

I've also got 8 RX8 yellow injectors to send off and get cleaned, they look like they're the perfect size, so thanks for the recommendation! |

Back in the US now after a couple of weeks away with work in Munich and a pitstop in the UK to catch up with some folks. Painstakingly going through the installation instructions now for the ITBs and trying to translate them to English. Time consuming, because as awesome as Google translate is, it struggles picking characters out of a line diagram.
I'll be visiting the 280Z after work today to turn it over and spin it round in the storage unit and make sure everything is still good. We have another two snow storms predicted over the next week, so it's not like I need to get it on the road for summer or anything yet.

Also ordered a full polybush kit. I know all the bushes are in terrible shape anyway, and I needed something else from the shop, and these were on offer etc. etc. etc. Now on the lookout for some replacement lower control arms as well to refurb in the future, so I can do them completely off the car (i.e. take to a garage to press the bushes in  ). |

I went to the storage unit yesterday - car hasn't been started for probably 4 - 6 weeks (and it's been cold as eff). After digging a ton of snow and ice away from the door, I had to jump the battery and the car warmed up absolutely fine... however...
There was a small amount of steam coming from somewhere near the thermostat housing. There's also a small puddle of coolant under the radiator. I'm hoping that it's just the cold cracking the hose a little, as the radiator is pretty new (and the hoses are not!). So, replacement hoses, clamps and a thermostat gasket ordered.
I was being super lazy about not wanting to take the inlet manifold off to get to the exhaust manifold, so I didn't have to drain all the coolant - looks like the car has decided that for me now.

More bolts lying on the ground can only mean one thing... Heatshield is off. Exhaust manifold is off. Turns out you can't remove the exhaust manifold without removing the inlet manifold. Inlet manifold is unbolted. Left the fuel system to depressurise over night, then I can take the fuel rail off, and finally get the exhaust manifold out of the car. Now that I've taken all this off... should I just fit the new ECU and go straight to ITBs?  |

Because I've had some good fortune here with asking questions, I have another one about fuel pressure. I was planning on just reusing the stock FPR for my ITBs, but it will look pretty ugly and this seems like a good opportunity to add in an adjustable one. My question is - how do I know what fuel pressure I should be shooting for? Is there a formula for determining it? Any links are appreciated! Edit - I found this: blog.cantonracingproducts.com/blog/how_to_estimate_your_engines_fuel_flow - very useful. As I'm not going for more power, looks like I'll get it running with the stock FPR first, then possibly get an Aeromotive one later. |

We have separation! Manifold out, had the O2 bung welded in this morning. Figured I'd wrap with whilst it's out of the car as well, because the ceramic coating looks a little rubbish now.  |
