hey as some of you may or not know benny as a little 2.1 zvh under his hood, now this is a 2.1 bottom end married to a 1.6 head! so its still got the runnin gear of a 1.6, what throttlebody should i put on or should i just leave it alone, seen a few peeps on here talk about a 2l mondeo one? what else is there? any idea please! :wub:

there are a few you could use, e.g mondeo 2.0, or possibly the v6, or granada one

ive never actually looked at the v6, but the 2.0 does fit with very little modding

 

are you running n/a zvh or turbo?

as n/a aint forced induction, its better to port the inlet manifold aswell, in order to fit the mondeo throttle body, i think all you need to modify if i remember correctly, is the arm to the other side, so that the throttle cable can connect

 

is it a std cam? if so i'd consider changing it for the ultimate road 285

id also stick in some mondeo injectors, along with the throttle body, then adjust the standard fuel regulator just to increase the presure

but just keep the std ford springs , you dont need the double valve springs , fords are strong enought to cope with 8000rpm

also check ebay for a cheap bluefin, i paid around 100 a few years back for mine,

 

what gearbox are you using?

its got the best kent cam init you could with out it cuttin out, its had some 5th injector work done at msd in blackpool and iv e still got the original 1.6 box, im not sure what injectors are init, im presuming its still a 1.6 head, the guy that built it at road and ralley told me nothing, its like a big secret and im not allowed to know! i do know its 150 bhp and i think thats pretty crap for a 2.1 with a cam, k+n and full system!

oh and whats a bluefin? im feelin a little dumb now! lol

cheers for all your help, really apriacate it

40's or 45's would go but that would mean ditching the efi and getting a manifold and fuel pump

 

but instead you could get throttle boddies, but it all depends on how much you want to spend,

the bluefin, is the superchip, but it installs on the side of the ecu, you unscrew the plate off the side,

disconnect the battery, plug it in, reconnect battery, job done

its mfi injection though? didnt think they had a ecu of such

 

 

nope, this cant be chipped, i thought you had efi

you can still change the manifold etc, i would be looking at swapping to carbs

that would be the easiest option

exhaust manifold or inlet? if its exhaust already got a magnex one on, does all the other advice still apply ei changing the injectors and stuff even though its mfi?

dont think you can change them benny, thats probably why you've had 5th injector work done for the extra fuel, the way forward from here m8 is twin 40/45's or an efi coversion I reckon, either way - I reckon it'll be costly, but reckon you'd be better off woth carbs??

for the efi you would need to drill a hole in the block to fit crank sensor, change the loom and a few sensors, along with inlet etc

 

where as if you go for carbs, id prob go 45's since you have the bigger bottom end,

all you need is fuel pump with regulator , manifold and twin 40's - 45's

i had a set of 40's once and the manifold, but a mechanic that builds race engines told me i'd properly gain nothing by sticking them on, he even offered to fit them! so i sold them lol

r1 throttle bodies? hmmm

or you could just use a decompression plate, change the manifold to turbo, put on a t2 of fiesta turbo

add an oil cooler, a small intercooler

and then you have turbo running low boost you shouldnt melt or pop anything

all food for though, not really a fan of turbos, like normally asperated power cheers for all you help bud, gonna go with a 2l mondeo throttle body get it set up and see what money i got shame the mfi is so restricting!

turbo is the way forward, its cheap power, n/a is ok, but from the grin a turbo will give you , also help to challenge

the speedo vs revcounter to see which one gets around quickest and you can double your power for not alot of coin!

wouldnt fuelling be an issue though with it only being an mfi? really need to remove that rev limiter too, wheres the spring on the dizzy? its hitting the red line before full power deleviery, thats what the rollin road guy said, and its hits the rev limiter before it its top end! its now fun bouncing of the limiter at cough cough!

theres the stopper underneath the accelerator pedal, and the spring is normally inside the cap, it had a pin that you push in and out with your finger, you can put in a stronger spring, or try removing it, just pulls out, and pops back in
