thanks but it dosent really tell me if the 440s are ok at 330-340.it states upto 320 and the next stage starts at 360 so its missing the inbetween bit which is what im after.typical lol.

what im trying to do is up the power from 300/300 to 330-340 and was wondering wether i could avoid the big cost of 550s as i dont want to run 350 for the safety of my gearbox etc,but really want 330 or more. is this possible do u think? im running vf35 and was mapped with a 2 port bs with standard tmic,ive now got sti8 tmic,3 port,ported headers,and uppipe,and the adjustable fpr.can i get away with not forking out for the monster price of 550s???

With the mods you`ve mentioned and a good fpr you should achieve 330 or close to it,but every car is different and to TBH your pushing the limits of many of the standard parts on your car,rods,pistons,crank,clutch,gearbox etc on a classic are close to there limits at this kind of power and there life expextancy will be grately reduced beacause of this.

if your lucky mate. try and get a good set of 500cc blue injectors
reasonably cheap to get, but at the same time hard to find
i was always told 330/340ish
tidgy got 343 with his 440cc injectors
dont know if he has an uprated reg though.
550cc injectors tend to hold value these days

You mean injectors like those?
SUBARU Impreza STi GC8 V5 V6 Injectors 500 cc DENSO 99~ on eBay (end time 28-Jan-10 06:30:32 GMT)
Are they worth anything? Isn't it some sort of cheap Chinese copy with Denso signs?
cheers

99gw... check these bad boys out!:-
Subaru Impreza version 5 / 6 550 Fuel Injectors on eBay (end time 25-Jan-10 20:02:17 GMT)
I'm sure they are Power Enterprise jobbies - one of the best brands! Plus seller says he had 'em off JGM so, if so, will be totally fine.
Even if you end up paying the full £250, I'm sure you'll not find cheaper (esp. PE ones!)

99gw, never mind.
If you do get a FPR (and I've been advised from a respected specialist that really you are better off with the Fuelab one), then you can run 440cc inj. at a minimum 3.5bar static (instead of the std 3bar). This should allow them to run at c.470+cc, which should allow 330bhp - as borne out by harvey, above.

(if i can find some when the time comes?) going round in circles here lol,ive got to buy 4 tyres and service motor first so gonna be a while,but u have gave good info which i can benefit from,just still not sure which way to go now,dont want to go 350bhp as i dont want to break the 5 speed just yet,so 330-340 would be ideal.im sure u can see where im coming from as regards paying out the extra for NEW injectors and running it at 340bhp,where it looks like 330 on the 440s is do-able but with a fpr thats gonna cost the price of USED injectors!
thanks joz.

In that case, I'd just get mapped on your 440s and see what figure you make! At the end of the day, it's gonna be around the 330 mark give or take. I'm sure the 'number on the page' won't bother you once you rip it up the highway for the 1st time! 
Re the 550 route... Flawed thinking if you feel you could reliably run the 550s on the stock OEM FPR - you'd really be better off, in the long run, to have the new FPR in addition! to the 550s (your OEM one is at least 10 years old and there'd be no way of infuencing how it will control the 550s...). After all, with that sort of fuelling (410bhp potential), you really wouldn't want the inj to run erratically/lean! at high loads, simply all because of an iffy old FPR - curtains! You'd hate yourself.
