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. :D

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.

[dave_mito]

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?

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.

[expolicev70t5]

Reason I was looking at Greens or VXR's was because I was considering one of John's (Dream3r's) maps and he states you need these injectors to run with it. Originally I was going to run with an MTE map and this would not need the uprated injectors but after reading about over boost I'm little dubious about MTE now.

The 2.4 t5 map is written for vxr injectors / john compensates from speaking with Shem, as shem is mapping mine once all p1 projects are finished

No, I know that. I was just questioning what James said as he was referring to changing the injectors without remapping the ecu. I know that changing from greens to VXR's on my S60 caused no problems without alterations to the map.

[JamesT5]

Baiscally, from what the remap specialist told me, he said that the injectors need to be 'told' to squirt the fuel out for set period of time to avoid over or under fueling.

On a foot note, he said that he can set engine timing to accommodate 95 RON fuel but you'd loose a few horses. However, having the engine set to run on Super Unleaded and then using 95 RON will cost the driver even more lost horses. The ECU will adapt and run with less power quicker than it adapts the other way of relearning it's 'potential' when refilled with 98 or 99 RON again. I had an interesting chat with him.

So who's the "remap specialist" then? Interesting to know other companies/people who are/will tune Volvos.

On a foot note, I can't get my head around why anyone would want to run regular unleaded fuel. The only reason is because it is cheaper. If someone really needs to save 3 or 4 quid on the price of a tank of fuel, then you shouldn't be running a powerful 250+bhp car capable of 150+mph. If your a cheap ass on fuel, what else are you scrimping on?! Just don't get it.

I did drive from the southern with blues in, whilst Martin had my greens for a refurb (which he sent on a few days later) the car was not a happy chap lol. Wasn't such an issue as nicci was on half term.

Mine certainly doesn't like cheap fuel, I get ghost codes and 17mpg compared with 22 on nitro plus and no issues. Plus cheap Lego toys for Evie.

Tescos do 99 you know!

[JamesT5]

95 or 98/99 RON seems to make little difference on my T5 at the moment because apparently it's "like a sieve" according to the guy who did the smoke test for me, plus it's running a factory standard map. The handbook says that the car will run on Unleaded (91 RON) but Premium Unleaded (95 RON as we know it) is preferred.

To be honest, I can't think of anywhere that sells 91 RON unless you fancy a trip to Poland out in Europe somewhere.

[JamesT5]

Tescos do 99 you know!

Yeah but I've heard it's not as good as Shell V-Power Nitro+.

[JamesT5]

Apparently, the remap guy told me that Octane Boosters are a waste of money because they don't work.

[Ettienne]

What nitro plus 102? It used to say on the pumps but doesn't now

[JamesT5]

V-Power Nitro+ is 99 RON.

[JamesT5]

V-Power Nitro+ replaced Optimax iirc, which was 98 RON; the same as BP Ultimate and possible Total Excellium).

I use 95.................don't really see the point in using super unleaded for my car ;)

[theflyingbrick]

I just sold a set of blues for 50 quid posted!! I now have a set of greens that I would be willing to sell but I need to get bigger replacements first if your interested?

[Dream3r]

Is that the same case on a P2 though?

Nope, there is the injection quantity plus a few other maps to consider on P2.

That will work, assuming the car comes with Greens, from experience. Bosch injectors are fairly similar and you have a decent adaptation margin :) Greens to VXRs == no problem map wise.

Thanks for the offer but think I will run with vxrs

[Dream3r]

FWIW greens are my preferred option, just because we have FACTORY calibrated maps for them from the R.

I'm just being picky, VXR's run fine.

John which intercooler is it from kl? With or without sensor fixings? Are a link even better

[Dream3r]

With, might be worth looking at do88, their new one looks pwetty

[Ettienne]

If you have a link for both.

Not sure about the sensors if it's with or without

Annoyingly Do88 wont ship to england because of a deal with pfs and it doesnt look like they are doing the same deal on the intercooler and pipework

[Dream3r]

You need the boost pressure sensor boss on the IC outlet. Or at least mounted before the ETM

[stribo]

The do88 intercooler has the boss on the outlet, and comes with a blank for cars without a BPS.

V-Power Nitro+ replaced Optimax iirc, which was 98 RON; the same as BP Ultimate and possible Total Excellium).

BP Ultimate and Total excellium are both 97 RON.
As you say James, V-Power is 99 and did replace Optimax which was 98.
Tesco Momentum has always been 99 RON and is, in fact, a very good fuel and IMO, as good as Shell V-Power.
I've used both and do not notice any difference between them. I always fill when range drops to approx 50 miles. I've never used 95 RON in my car. The handbook recommends the use of 98 RON or higher, not 95, although the car will run on 95.
FACT - You will get less fuel mileage if you use 95 RON and less BHP.

In March 2010, BP stopped sales of Ultimate Unleaded 102, citing the closure of their specialty fuels manufacturing facility. :frown:

Why anyone would want to use 95 RON or less on a Turbocharger car is beyond me. It will rob your car of power. The lower the RON, the less resistance to 'ping' or 'pre-detonation', therefore, if you use 95 RON instead of 99 RON then the knock sensor will detect pinking, retard the ignition timing and reduce the engines output.

[don kalmar union]

Good morning Paul

If indeed you are still giving some consideration to an MTE map then you under no circumstances need to change the injectors for any stock stages of their calibrations.

If, for your own reasons, you have decided to fit these bigger injectors then you should have a specific set of calibrations written which will be an expensive exercise for it to be done properly and will bring you no discernable advantage.

Don.

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.

4 bar is your standing FP @ idle, FWIW. As I have said I definitely recommend greens for the 2.4's but VXR's work.

Also greens are ~440cc/min @3 bar (to the best of my knowledge). That's certainly how Volvo calibrated them
