fuel injectors

[Scotty ss]

I've just got bought a k11 1.3 super sport and the lad who i got it off said it has primera fuel injectors in, is this good or bad and if good how? could u please help me:grinning:

 

[Igloo]

It's good, means that it has the capability to put more fuel into the engine, giving it more performance

 

[Scotty ss]

Aww thats great news i was talking to the lad today and he said he thinks that it might have primera throttle bodies and ecu but he isnt sure would the car need remapped or not?

 

[Igloo]

If it has the ECU from a primera chances are it wont run (or has been remapped already)

Most people go for throttle bodies and injectors.

 

[Scotty ss]

oh right tanks for the help its appreciated

 

[Robb]

what kind of performance gains can actually be had from putting big injectors and throttle bodies in?

 

[Igloo]

personally, i'm not sure (Not having done it) I presume faster throttle response would be the main thing.

 

[Cheef]

Also a capability of flooding his throttle body. igloo if he posts his pic of the set up, take a look at his fuel management.

 

[Craig]

You won't flood the throttlebody as it is mounted way before the injectors.
Craig

 

[Igloo]

Yep, the TB will be fine.

The ECU should be ok, just running primera injectors, if he wants to really go for it something like an e-manage if he's running bigger cams, turbo, etc etc etc

 

[Cheef]

I just overlooked a small fault. thank you Craig and igloo!!

 

[Scotty ss]

Personally i dont know what has exactly been done to the cars engine all i know is that it has primera injectors in and the lad said he wasnt sure if it had throttle bodies and ECU.

 

[Craig]

I have a non-NATS ECU if you want it.
Craig

 

[Scotty ss]

Wats a non-NATS ECU lol am new to the whole mechanical side i only do the spraying/refinishing bit lol

 

[Craig]

NATS is Nissan Anti Theft System - it is an immboliser that stops the ECU (and car) from working if the corret key is not used.
Craig

 

[Scotty ss]

Oh right thanks for explaining but how would i know if there was primera injectors throttlebodies and ECU in the car would it sound diff or just perform better?

 

[Craig]

You cna tell if the throttlebody has been changed if there is a plug dangling and a plate blanking off somehting on the bback of the body - also one of the coolant lines going into it is too small, so a larger piece of hose will be around it.

The injectors - the one by the throttle cable mounting bracket fouls it, so will either be spacered out (the bracket) or the injector will be twisted around.

The ECU is located in the centre console towards the bulkhead, there will be a part numbr on it, if you could post this up (if you can be bothered to check it - it is a bit of a hassle) then we could prob work out what car it was rom.

Hope this helps, Craig

 

[Scotty ss]

Yes thats a lot of help thanks and the car is at me mates house because it has no alarm and a dont want to leave it in my street so the next time i go to his house which will be next week sometime al check for all of the stuff you said thanks

 

[Scotty ss]

If its a primera throttle bodie will the plate be on the drivers side?

 

[Craig]

It is on the backside of the body IIRC and the larger hose is on the driver side.
Craig

 

[Scotty ss]

Theres a silver plate on the left side of the throttlebody does tht distinguish what car its from?

 

[Craig]

Not sure really, any chance you could get some pics up?
Is there 1 plug disconnected?
Craig

 

[Scotty ss]

Am goin back to the garage on monday so al get some pics then and am not sure bout the lead where does the lead come from?

 

[Craig]

It will be on the same part of the loom as the other plugs for the throttlebody.
Craig

 

[Ed]

IIRC Primera injectos are the wrong size and will not fit the K11. Given the probability I would say the car has stock injectors.

 

[Antony]

so not even the 1.6 ones then?? i find this dubious..

 

[Ed]

Oh 1.6 yes possibly. I admit i was thinking 2.0. I always forget they did 1.6. with that in mind yes could be fitted but it would be a horrid modification. as in totally pointless without them being 'tuned in' correctly.

 

[Low Rider]

The injector colour will tell you which injectors are fitted. Standard ones are grey, 1.6's are black.

 

[Davey C]

no point in putting the 1.6 ones untill your engine requires more fuel. any the standard ones are fine up to and quite a bit above 100bhp.

They will fit but as i say no need

 

[djlee_dj]

its a micra throttle body

the silver plate is the air flow meter, theres a plug going into the side of this 'silver plate' - yes ?

and its sealed in and not screwed ?

craig im not sure of the blacking plate you talk of either .... is it to block the AAC + FICD on the front of the 1.6 throttle body

i have a spare 1.6 throttle body, and also a 1.0l. they will be going on ebay monday night prob. also got 2or3 ECU's, for both. some have nats tho
