Hi, basicaly im building a zetec turbo for around 300bhp. Im using a rover 200 turbo inlet manoifold, with a focus rs manifold with its gt25 turbo.

I had the same setup before but with a cvh manifold and a T3.

Now that ive forged my engine and am aiming for 300bhp, what injectors do you recomend? At the moment they have red bands on them. I have no idea what cc these are but was thinking of going for 440's? Any idea what i need?

Cheers, Tom.

Rollinz

std focus rs one dude,
think there 440ish and there good for up to 370ish

TomPengelly

Whats that mate, standard focus rs injectors or inlet manifold aswell?? Just that ive already modified my head and ported it to match the rover inlet..

Rollinz

injectors mate,

but.. a std focus rs inlet is just the same as a 1.8/2.0 blacktop zetec, and on a focus rs they still good enough for 380 ish,

the only restrictive part on the focus rs's is the std exhaust manifold,
good for 300 bhp but after that a tublar is needed,

440cc injectors would be crying at 370bhp lol!
i had 440cc ones in my zvh chucking 23psi on a t3 through it and were maxed out at 4000rpm.
rover red bands should be fine for 300bhp though.

nevsrevs

think rover red bands are 330cc, what management are you using tom?

TomPengelly

Omex 600

Rollinz

tell that to lads on rsoc....

i personally had siemens 83lbs when doing 545bhp, but changing them for ID1200's

apparently they are 390cc, blue bands are 460cc IIRC

i use 60lb siemens in my zetec turbo and they are fine even at 20psi.

the rover ones may do high bhp, but they will be maxed out and no flex for any enrichments such as acceleration enrichments or extra fuel to combat high act's.
just had a big discussion on these injectors a couple of days back.

Im using the rover (lucas) blue bands on my zvh. They were setup and are fueling 249bhp. My friend is also using the smae injectors on his zetec turbo and he is getting 299bhp 360 ftlb.

BTW i thought red band were 340cc and blue were 480cc?

TomPengelly

There are a set of blue bands on ebay for 60 quid, if tgey would be better than the red ones i already have?

Rollinz

rover ones?? i was on about STD focus RS injectors...

maybe how the focus ECu conrtoles them is how they do up to 370???

personally i think it is asking for a bit too much.. but there are cars out there doing it

TomPengelly

Do you think the focus rs injectors would go straight in the rover manifold?

Rollinz

not entirly sure tbh mate! i dont know what the rover inlets are like etc..

in my honest opinion, for what your wanting to do, everything thats std on a focus RS is avaliable reletevly cheap and easy to fit with no "alterations" to make,
simply bolt together and away you go,


heres a simple modd'ed focus RS and results

Full Mongoose inc de-cat
Adjustable actuator
Forge re-circ
K&N panel
AE base map with blufin


remember this car is still runing std exh manifold... and only 18 psi boost....

Rollinz

oh and dont forget thats with the restrictive MAF as its on std ecu..

you been on standalone would achive ALOT more

Rollinz

there you go mate... words of jonnyfrs over on RSOC

nevsrevs

im with rollinz on this 1, you got the focus log mani, good, gt25, good, i would be thinking about running focus injectors, i have seen to many t16,s melted due to lake of fuel, i know mainly due to crappy MEMS ecu, but still would not trust a old set of rover injectors

Rollinz

exectly and i started a topic over on RSOC mk1 forum for you mate and here's a reply...


there ya go and thats talking about a COMPLETELY STD focus rs engine

TomPengelly

Thanks a lot mate! Thats a plan then!

Rollinz

oh and just to add....

focus RS's have a lower pressure fuel regulator....
so if you grab a 2.0 inlet and fuel rail and reg.. use focus rs injectors with the 2.0 n/a reg... its a modFRS owners do when having a custom map

nevsrevs

good path your heading down now tom, should have a easy 280-300 bhp, but with that turbo they are just squirt and go, really usable power, loved my old set up, so responsive,

Rollinz

when you get bored of 300 there is a hybrid GT25 that alot of people use too..
one guy with figures of 378bhp & 365lb/ft, with a slipping clutch!

TomPengelly

Cheers for your help boys, really apritiated.

nevsrevs

they are a brilliant little blower, really underestimated, wat car is this going in tom?
we managed to squeeze 300 horses out of our gt25, things stated getting too hot after that, and that was on ofab,

TomPengelly

Its going in my series 2 escort rst. I would like to run it at 300 this year then next winter invest in area six inlet and big injectors, tubular exhaust manifold and GT30? For around 400 - 450bhp? But thats for 2013!

Rollinz

very easily do-able mate and dont forget to use 1.8 cams

but instead of buying expensive area six parts... (i know ians work is good)

how about have a think of this stuff.....

TomPengelly

Very nice mate! What is it?

Rollinz

GR Performance, custom made.

cheaper than area6 by a long way, and definatly works... 545bhp @ 1.4 bar

TomPengelly

Whats that, custom inlet and exhaust? And what turbo do you run?

nevsrevs

wat price is that inlet rollinz, whos flow bench has it been on?

Rollinz

inlet without fuel rail is Ł600

not been flow tested just "tried out" on my car and had good results,
all cylinders seem to get equal flow when "off boost" and its cleaerly working "on boost"

the velocity stacks are a one off design too (i will PM you details but please dont make public!)... gaz at G R isnt going down a route of making loads as he's more subaru/evo orientated so the inlet is made to order,

nevsrevs

i would like to see it on a bench, looks like its doing well on your car though, ians is 750 with fuel rail and fittings, so not loads cheaper,

Rollinz

must of come down then., cause when i priced it up (well over a year ago) it was going to cost somthing like Ł1200 ??

anyway, ATM my car is in bits waiting for my double valve spring conversion to come back,
while the inlet is off.... who does bench testing of that sort?

Rollinz

yes custom inlet and exhaust, on a GT35... changing that to a GTX30 tho....

basically.... forged engine... (CGI block tho) STANDARD HEAD!, customs intake and exhaust... 545 bhp

nevsrevs

ian has his own bench, so when your heads there ask him to test it for you, if you like,

Rollinz

he's already got the head.. still waiting for it to return!! but i will give him a call :thumbsup:

nevsrevs

yea it would be cool to see it being tested compaired to the jenvey and such like.. looking forward to you having your motor up and running again..

TomPengelly

Im gunna order a set of 106 gti springs tomorow, is it just the springs i need? Can i use the zetec caps and collets? Cheers.

Rollinz

you need silvertop collets and retainers IIRC!! , maybe worth checking with somone else too!
