This is something i've been wondering for a while...
OFAC stage 2 - 195bhp, Uses "701" beige injectors that flow 230cc/min
MS running around 200-230bhp people use Deka 630cc injectors, why the extra 400cc's for not much extra bhp...?
Is the answer in the MS itself or that the "701"s aren't really upto the task of 200bhp...?

Basically im planning on going to MS soon with a standard engine, bar a cam aswell as a 48/55 T3, fmic and aiming for 200-210ish bhp with around 220lbsft... What injectors would i need with MS?

 

701's are not really up to the job of 200bhp+ from what Stu @ MSD has said, I ran VXR 480cc ones to start with but they topped out at around 230bhp so upgraded to Deka IV's as I wanted to run more power.
Plus they are brand new, cheap and have a much better spray pattern

 

As above, im not running them yet but will be soon, if your thinking of new injectors you may as well give your self some head room for future upgrades (you know you get bored of 200 bhp Roger )

Rob,

 

is it true that you can use punto gt injectors and they are better than beiges anyway and cheaper?

 

basically injector and ECU design have come on, so it's now not a problem controlling big injectors.

 

Any links for the deka IV's? anybody

 

ive just picked up a set of 650 deka injectors that should see me fine to 400hp.............. all tho ive seen my kms ecu controlling 1600cc injectors on a 1.8 at lambda 1 on idal

 

So i can run around 200bhp with the deka's? Just with less duty cycle right?
Maybe the vxr's would be a good shout, as i won't get anywhere near 230bhp.

Impressive!
Thats right mate, but with your stage 3 T3 you can make an easy 250bhp so I would go with the Deka's.

 

250bhp? You think... Thats more than i'd planned! Altho im 100% stock on engine internals, i might slip a cam in her one day tho.

 

If your engine is 100% stock then I wouldnt want to push more than 230-240bhp through it, the rods are your weak point.
Also if it's never been rebuilt then you will be down on compression (ring wear) and the head will not be breathing as well as when new (cam/lifter wear) so you may not make 250bhp but it wont be far off! With a good FMIC and mapping of course!

 

Wheres the best place to get the deka's or the vxr injectors?
I would like to see around 230bhp from it eventually i guess, once ive got a cam and maybe had the head ported etc. But im not really chasing numbers, just want to get a decent set-up with room for future improvement!

 

Deka's are in my link above and for VXR's there are plenty on ebay last I looked.

 

what are the vxr injector out of? my work have just took on a vauxhall commercial dealer ship so could get them at cost price. what cc/min are they?

 

Astra VXR, 480cc/min @ 3 Bar, good for just about 230bhp in a RST.

 

Sorry m8, didnt see the above link... Nice 1!
I'll scan ebay and maybe ring my local vauxhall dealer about the vxr 1s too!

 

cheers karlos, fancy the dekas but got stung buying from states before. not willing to pay uk prices so the vx are an option for me.

 

wrong quote?? feckin phone! lol

 

Are VXR injectors a direct replacement for the EFi?

 

apart from a remap, yes.

 

If I get siemens deka's from usa am I likely to get hit for import tax and does anybody know how much it is?

 

Not if you tick the box to have them sent as a gift no! Otherwise I think it was about £50, Sean (xr2wishy) on here bought some and didnt notice the box and got stung.

 

Any advantage of running the deka's as opposed to the vxr's at 200bhp...? Just more scope for a power increase?

 

More scope for future power hikes, and the more people running the same type of injector means that more base maps can be shared etc.

Rob,

 

Yeah as Rob says.

 

Ok sounds good...
Cheers for the advice guys, as always its much appreciated!

 

i bought something, was apparently sent as a gift, dhl still raped me for 30 quid! twats!
