I 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.
