Evening all,
im currently modifying a set of Nissan Pulsar GTI-R tb's to fit a big block XE, i plan to run it on standard management, so i can use the standard tps & afm like so:

dodgy diagram i know lol but you get the general idea,

similar to this ^ just mine will have the flange cut off before the injectors.

Also im guessing i'd ditch the idle control valve? Seeing as i want to use standard management for the time being (dont really wanna spend £500+ on management just yet..) what sort of gains would i expect to see if any with this setup? if theres anything ive missed/ over looked please tell me rather than telling me its a **** idea etc. as im only young and still learning :)

you need the icv for cold starting & running. mappable systems just put more fuel in till they are warm.

i wouldn't like to guess what hp it will make, but with a bit of development work, it should be quite good

from what ive read elsewhere i was under the impression that i wouldnt need a icv as once the engines warm it should keep itself running as such? wouldnt be hard to put one on though as theres a ridiculous amount of breather/outlet things on the tb's

Im aiming for 200hp N/A on the engine, with other things like enlarged afm, uprated injectors, a suitable map would it be capable of that? or would i need higher compression pistons & some lairier cams? i dont perticuarly understand the workings of fuel injection so forgive my ignorance if im spouting drivel lol its something i need to readup on :tard:

injection is dead simple

a device measures the air coming in, and combined with the throttle position, the current revs and temperature of the engine, it decides how much fuel to dump into the inlet.

making it work right is the big problem..

this setup would work straight away if you fitted the std afm, tb, and all the extra pipes & ancillaries to it.
you will then know if it is an improvement over std, and then work on it bit by bit. obviously a stand alone setup would be ace, but a remapped factory one would do well too.

this is what im wanting to do, but instead of having a single tb i want to use these ones, engine wont be running for ages anyway, i havent finished the shell of as of yet lol :(
