VXR injectors for 2.4T5

[expolicev70t5]

I am looking at putting VXR injectors on my 2.4 T5 prior to getting it mapped, I've tried local motor factors to get some but they are wanting reg No. etc to be able to get them in stock, how have others attained the correct ones? Im assuming they are just from astra / zafira vrx, is there a specific year that suits v70? as it might be better to just get a fuel rail with injectors of ebay, advice would be much appreciated as I initially tried to get Volvo green injectors but they could only get me 4 and no chance of future stock.
Thanks in advance Paul

My advice is get a set of 4 on a rail from ebay and then see if you can pick up an 'odd' one to make it up to a set of 5.

I'm told, reliably by a tuning specialist, that if you put VXR's on the car then the ECU will need to be calibrated to take full advantage of the higher flow rate. If not, it will just squirt fuel through but won't regulate it properly and the car could just 'over-fuel'. As I say, not from me, this came from a tuning specialist with 25 years in the business.

Get a set of greens,not much diff in the flow but easier to find

[Jamest5r]

You can buy them in singles without the rail, i bought 9 singles last time 5 for me and 4 for smithy, so don't believe every post written

[expolicev70t5]

I tried to get greens initially but failed hence why I looked at VXR's local motor factors could get me 4 greens but that's all supplier had with no future stock coming in.

55556799 is part number for singles from vauxhall retail of £81.50 plus vat
55556798 rail with 4 retail of £149 plus vat

0 280 156 280 is bosch number if your trying factors

[ExternalError]

I found it cheaper to get 4 on the rail and 1 spare one in terms of cost i just searched ebay for the bosch part number in the post above found someone selling a few rails and asked if he would be willing to sell 1 single. Cant remember off hand how much i paid but it was less than a new set of greens

Courtney Motorsport sell VXR's for around £140 for 4. But they will only sell you 4 as far as I know.

Tim Williams just got me 5 for the 850. He has to buy them in batches of 4, so he may well have spare odd ones, but can't be sure. Might be worth a PM.

[S70T5Chris]

Doesn't the 2.4 T5 already have greens though?

[expolicev70t5]

No my explode came with light blues

[Ettienne]

All come with blues (2.4 t5) iirc, only greens are 2000 v70r, s60r / v70r p2

No idea about late t6s

[Ettienne]

I'll be putting vxrs in the v70 when I map it, takes the strain off the pump.

[abdul]

Can u put these in a v70 r 1999 awd

[abdul]

What difference would these make

Who said that?

I put VXR's in the S60 without changing the map. The ECU adapted fine, and the fueling was fine. Maybe that wouldn't be the case going from blues? But can't see it being much different at all.

People with the old P1's chuck in blues, for example, without mapping for them without issues, and that has a far less sophisticated ECU than a P2.

Kingsford's ex plod made an extra 12bhp with just greens and a catback (272bhp)

ALL maps will be mapped for a certain injector.

I was running a HLM map on blue injectors and it popped and farted on the over run also you could smell the unburnt fuel in the exhaust.

To get the car through it`s MOT I had to fit orange injectors with the HLM map.

From what I`ve learnt from mapping my car is the map is written for a certain injector when going for large flow injectors like greens etc.

For example,

A map for whites has a Grundanpassungs faktor (Injection Basic Adjustment Factor) of 0.9063

while a map for greens it is 0.7735

If you where to run greens at 0.9063 it would run rich and lean if you ran whites at 0.7735

So to chuck any old injectors in a hope for the best is madness

ALSO

VXR injectors at 3.8 bar are only just a bit more flow than greens, VXR injectors come into they own when run at 4 bar.

Is that the same case on a P2 though?

[T5RatherAmusin]

Blues 350cc/min at 3.0 bar and 395cc/min at 3.8 bar.

Greens 405cc/min at 3.0 bar and 465cc/min at 3.8 bar.

VXR- 470cc/min at 3.0 bar and 528cc/min at 3.8 bar.
