quick question..

are all the 3.5L ke/th/kh/tj/kj/tl etc etc 3.5L 6G74 injectors the same impedence and flow..

like if i plan to pull some injectors out of a wrecked car, get them cleaned/tested etc.. as long as it's a 3.5 it will be fine..

just trying to minimise vehicle downtime

Yeah as long as they are from a 3.5L magna/verada then they are the same (275cc factory rating). Ive used KF/TH/TJ and 380 injectors in my 3.5L build ups over the years and not once did the injector scaling need to be changed to run them.

The 380 injectors are a "better" injector overall as they are 12 hole units (better atomisation) compared to 4 hole units in the magna

Keep an eye on e-bay, there were 380 injectors that went cheap yesterday.

How cheap?

I think they went for $110.

Are these a necessary or worthy upgrade for a tuned magna engine - the 380 injectors? What would be the benefits?

Next to F all lol.

Seriously the 12 hole injectors are meant give better atomisation over the 4 hole injectors, having said that i found no power/torque advantages with them fitted to the donkey engine compared to when i had the old 4 holers in it, economy didnt seem any different either. They may be better suited to a more milder engine though

The new larger CC injectors i got from raptor are also 12 hole units.

Also interested in answer.
Although I'm thinking if your injectors now arnt maxxing out then there isnt a need. Youd probably need a high flow fuel pump first before bigger injectors

Thats the way the IPRA Magna guys have gone with their 380's..Evo fuel pump....stock injectors.

Yeah and there injectors are maxxed out (close to it), so dave tells me.

When i had the 380 injectors in mine they were at 95% duty cycle and causing lean out over 4700rpm, this was with standard "rail" pressure. When we bumped the rail pressure up to 50psi it allowed them to be "ok" (although still abit lean for a street car etc) but with this increased rail pressure it made the fuel pump hum louder, hence why i went bigger units and now there is no need to run higher than standard rail pressure and its also helped quieten down the whining walbro (whinbro lol) fuel pump a bit.

Ok....they were saying the stock pump is on it's limits at 210-220 kw as well.

The stock pumps limits seem to vary heaps. Some can get 200kws out of them and others struggle to supply fuel for 150. In all honesty a higher flowing fuel pump upgrade is cheap and easy insurance against any lean out issues due to a struggling pump. It was the first thing Steve asked me the day my car was leaning out on the dyno.

mine started crapping out at 137kw. $200+ later I gained 7kw more. Bang for buck = win

so are the 380 injectors still 275cc? or what your saying is the the factory ecu will compensate slightly for the slightly larger injectors?

my motor is pretty much stock.. and might end up staying that way.. can i just 'aquire' a set of newish 380 injectors and use them straight up..

all i want to do was grab a spare set of injectors, drop them off to a shop, pick them up the next day all cleaned and then on the weekend, swap them out, and replace the rocker cover gaskets/tube seals, give everything a clean up.. one morning on the weekend..

Yes......don't know that it would be worth spending the money on cleaning though.

Yes they are still rated the same as the 3.5L injectors and yes they will bolt straight in and be a goer.

I have a set of 380 12 hole injectors that are virtually brand new (I bought them brand new), they have done about 1500kms of work in my magna, so they wont need cleaning etc.

Let me know if your interested and we can work out a deal/price.

i got my 380 injectors with everything else connected, for $40 :D

did you notice a difference snow?
