Injectors upgrade for AGU

[Hulmie]

at that point they may be sruggling but the main thing that could restrict you is the standard fuel pump. like i said get a good inline fuel pump, calibra yellow injectors and a 4 bar fpr. this will then ensure the car is being able to fuel the engine easy enough and then just a case of working around that. Rather than having the car set up only to find that your restricted due to weak fuelling system.

But, those injectors will be plug & play? I don't want to adapt injectors. I would like to replace only but with a higher CC.

[Hulmie]

just replacing injectors wouldnt really make a benefit as if they have a higher flow rate then the rest of the fuelling system needs to be able to supply them and then also map set accordingly. Yes they are a direct fit on AGU's

Remember someone said uprating injectors early could be harmful to the engine, only whack them on before the remap as apparently the rate and duty could be harmful in the higher rev's not sure how true this is?

[mendonza]

I wont fit them firstly. I'll fit them before turbo swap and remap. I'll buy a walbro 255 next month to feed the higher flow injectors.

without them being mapped they will run richer higher up the revs..

[mendonza]

without them being mapped they will run richer higher up the revs..

What do you mean?

[tech1889]

They will run the car fine.. but until they are mapped because of they're flow rate they will run the engine a little richer up the revs well thats what ive been told.. just fit them and then get the car custom mapped to suit to get the most out of the fuelling etc..

[golf-sib]

Thought bigger injectors can do alot more worse damage, overfueling a bit can be helpful as it can aid in turbo cooling etc, but a tad more overfueling and you would get bore wash?

[tech1889]

I wouldnt run big injectors for a prolonged period but putting them on for a few days before you get it mapped there shouldn't be any harm done..
