the inlets can be converted to run top feed injectors, needs a fuel rail adapting to fit though. i used an alfa 155 twinspark rail and made it fit to the inlet, but the iscv needs relocating though.

I dOnt know Personally mate, but thats whats in mine from advice because double springs are too harsh

All i can tell ypu is what ive done to mine is working, its pulling mega power and only at 1.5 bar,
I think i should be able to crack 620-630 bhp by the time the mapping is done

Rollinz

Again even the plastic 2.0 inlet tha uses on the focus rs, with focus rs injectors and std rail and reg

All will run up to 350-380 bhp

Problem with focus rs inlet is that it won't fit in a mk2 fiesta engine bay

Wake up and smell reality.

Rollinz

Sorry
Didnt realise you had built and speccd my engine

Its doing 545.4 now at only 1.5 bar, So i dont think im been too unrealistic tbh

Rollinz

Ar right i see,
Well the ho inlet will have to do then lol,
Just convert it to top feel injectors and should be fine,
Will definatly make the power you want,

I take it ill have to convert to top feed injectors as the standard side feed wont give me enough power?

Rollinz

Tbh mate im not sure,
And dont know if you could just buy some uprated side feed ones,
Might be somthing to look into,
If you do convert to top feed just get some vxr injectors, can pick them up really cheap and they will flow plenty for what you need,
Iirc there about 450cc

Side feed phase 1/1.5 scooby injectors fit the standard zetec rail mate, i'm fitting them to mine
Gives a bit more choice, sr20 nissan ones fit as well, just the o-rings to swap about

Rollinz

Sorted then, saves even more messing about, and i supose std scoob injectors will be dirt cheap to pick up second hand

Yep
Considering most upgrade from standard and the standard greys are good for 320ish bhp iirc then they are quite a good option if you want to keep the standard rail.

nevsrevs

you can buy uprated ford side feeds 440cc called f1,s as i think they were made to run in a ford f1 engine back in the day, ian can get you a set about 200 squid

Would this OFAB management be any good to me? Or shall I go with something else?

MO' BENT RIMS

i THINK there ofab is good for 250bhp

i put in subaru legacy 440cc/min sidefeed injectors into one of my zetec turbos, got them for a tenner.

chaffe

you do have to modify the rail a bit though mate

QplateRST!

Seems like there alot of people saying you need this and you need that on here as always. U don't need to run an mtx gearbox imo mine ran fine with an ib5 for years and in the end the selector bolt came lose and It got stuck in second gear after taking near 50 runs or more at Santapod I only fitted the mtx as it came up in a deal! I still run a fiesta turbo efi inlet! ( I will be changing it to one of Garys in the future)

If I was going for 300bhp I rekon I could build a 12 second car for around Ł2000

Rollinz

This guys talks sense!

But you can still build one cheap and capable of more power in the future,

Lotts of people will have diferent views on what they would do,
In all honesty i dont think there is a right or a wrong way to spec you engine,
I went in a totally diferent direction with mine... And it works


Gearbox's.....
I use to have a s2 with a 2.1 ztec turbo pulling 300+ and the gearbox (std) held up fine,
Started to get a bit noisey after 8 months of constant abuse on fast road driving, but then i broke the car for bits,

i have run bc boxes for years and had a few fail, they do take a fair amount of abuse to be fair. the reason i upgraded to an mtx was that it made financial sense to me. also i have equal length driveshafts and an ATB diff, so torque steer is reduced.
i have run a zvh prior to the zetec turbo and on 1.5BAR of boost the rst boxes would last a while of hard abuse, but in the end they all start whining. what do you expect though, they were built for a range of cars from 50bhp upto 133bhp on standard cvh/valencia engines in various guises.

but remember there is next to no weight in deano's little monster which plays a big part into how these boxes last

I think if you were buildinf a car to be used on both road and track then an mtx is the way forward, although you could be lucky with the normal box as it is a bit of a lottery with how the last
