How do you know what size injectors to run?

[mukumu kurubushi]

I\'ve got the IAT, and im buying a Tomei MAP sensor soon (same Denso part number as the Apexi one, but Apexi have stopped rebadging them) so it should be pretty much plug & play.

The thing im not sure about is if they fit the stock loom, or will i need to fabricate my own harness?

The IAT you can simply use spade connectors to tap into the existing temp sensor harness and the map sensor is the same. I have done it this way for now as at least I can always take a step back to standard if anything ever goes wrong in the early stages. I will make myself a harness adapter like the Banzai adapters, really easy to do, I do expect to cut off any standard connectors eventually and have incorporate it all into the loom properly.
The temp sensor it does not matter which way round the wires go and the map is only 3 wires,
Br/B earth
Br/W Vref
Gr/Y Map

incidently they are the same as the FD map sensor which I have fitted atb the moment til my Apexi Boost kit arrives.

Just a quick question, do you need an aftermarket secondary fuel rail to use the 1680cc injectors?

And how much could I ask for my 1000cc\'s as they arent enough

Sorry thats 2 questions.

Grinder friendly prices are always best £3.50 and half a curlywerly is my best guess.
Seriously though If they are cheap enough I might be interested.
