Injectors for Supercharged v8 Question

[r2d2hp]

Hi Everone

Is anyone using GENUINE BOSCH FUEL INJECTORS 0280156280 470CC Z20LEH from an Astra VXR in there Supercharged V8's.

Seem to be readily available and good price too

Anyone any info on them

regards Reg

Size for whatever sort of power you hope to make, and a little headroom.

Are those injectors the same impedance as you need ? What are you using for an ecu or control ?

Hi Stevie

Ecu is an emerald. I did email to them but it bounced

Will try calling them again to see if 14.5 will work

I was sizing for 440 rwhp. What do you think

Sizewise they should do ok and they do appear to be high impedance ok from searches. Even if you needed a little more flow you can easily bump up fuel pressure.

Must admit I'd prefer new injectors, but really there's probably no reason second hand OEM ones would not be fine. They rarely give any bother.

A quick google for even VXR injectors...seems to throw up a lot of new options at very low money. I'd wonder if these are genuine or Chinese.....the dangers of the world we live in.
I'd probably sooner buy a set of known second hand OEM injectors before a set of these cheap unknowns.

ASNU could do new whatever you need

Or last set I bought for myself I used these guys

I'm sure I've a couple of sets of Siemens 600cc's lying about, short and long I used to use. Certainly they were fine when I stopped using them, but they'd have been lying about now for several years
