fuel injection or carbs?
Hi I'm looking for some advice on what to do with my current engine in my westfield project. I currently have the 1.8 zetec the guy who I bought
the car from said he sourced the engine from the ginetta cars I took the rocker cover off and it has the uprated cams installed so it has been played
with.
I'm currently completely rewiring the car as the looms are a mess now am I best staying with the standard intake and fuel injection or going the
carb option looking for the best set up the cat will be mostly used as a track toy.
Also the current air intake is routed so the filter is at the back of the engine bay is there a better way of routing it so it gets cool air
Thanks

Does the car require a CAT for the MOT, if so better off staying with injection.
You can still run OEM injection if you move the throttle body to the front and duct away from hot air, you could always duct it from the side anyway,
as long as it does not catch hot air.

Bit of a Newby on all this how would I go about relocating the throttle body to the front? The car will require mot but I should be ok in that
department if u know what I mean ha.
What gains would I honestly expect to see from switching

If you are already dragging in cold air then there is no need to worry about playing around with the intake.
If you have a mappable ECU then fit throttle bodies not carbs.

How would I find out if my ecu was mappable thanks for the info I appreciate it

Stick a picture, description, part number etc on here, someone may know.

Injection, definitely IMHO. Played with carbs on and off for a few years, and they are a brilliant, but dying artform to get set up correctly. Stacks
of people out there who can help with injection set ups.
If you arent planning on doing this work yourself, I'd go with Injection.

Fuel injection without a doubt. You allready have the sensors, and going to carbs is a backwards step. For a good engine upgrade, look to getting
Indivdual throttle bodies, and an aftermarket ECU (Assuming car is currently running a ford ECU). With the cams you have you should see at least
155bhp.
The cheapest route for this is Motorbike TB's and megasquirt. The expensive route (but probably far easier on the installation) is Jenveys and
Omex, Emerald, DTA, etc, etc, but cost for a rolling road session

Ok so my ecu is a Ford the info on it is
sme-405 jest eec-iv
97ab-12a650-job d2ru06b72pn9 cad 7 25
Thanks once again for the advice guys so looks like throttle bodies is the way forward with injection system.
Now for my next question the megasquirt I understand is a stand alone ecu that will require mapping with the throttle bodies but will this replace my
standard ecu? Also looking on ebay and that there is different variations of it the original and then a newer version which would be the best for
what I need?
And yes I am on a budget so bike throttle bodies are the option I'd go for now which 1s will work best with the 1.8 zetec and where could I
aquire all the adaptors for them?
Thanks
Mike

We use megasquirt V3.0 MS2
We get ours from ExtraEFI.co.uk
http://www.extraefi.co.uk/MS_All_products.htm you need an MS2 for a zetec £390
Let me know if you need any help, we have been tuning megasquirts for years.

the question is how big is your budget ?
bike carb's and megajolt or nodiz would be a budget option if you were starting from scratch wit ha bare engine...
but since you've got the stock EFI setup already then the cheapest option will just be to stick with the setup you've got 
there are a few old threads on here about using the ford ECU's
if you want to upgrade a bit you could start off with a programmable ECU like megasquirt and keep the single throttle body for starters and then add
bike TB's as funds allow...

My budget is a running cost really there isn't an actual cap on it but I don't want it getting out of hand bike throttle bodies is the way
to go I think how much would I be talking to go this route and where could I get them from?
Thanks for the info on the ecu

you can pick up the bike TB's from just about any bike breaker or even just off ebay - but shop around a bit they can vary in price a
lot...
FASTdan on here is your man for the manifolds and bit you'll need to put it all together - he sells everything from flanges to make your own DIY
manifold all the way to complete kits inc the TB's

Is there a particular set that are easier to install or set up or are they all the same? Also is there an adapter plate to mount them and where could
I source 1

GSXR 600 / 750 TBs would both be fine for an 1800 zetec, the older ones are probably more useful as they can be individually spaced. Other option is
to not space them and buy a manifold to fit.
There are probably others out there, so worth looking around.

Are all gsxr throttle bodies the same and could you point me in the direction of a manifold suitable for them

From my notes the jest ecu was from the last of the ford escort gti's despite the badge it would only be a 115 ps spec.
So breathing mods and cams aside you will be getting around 125bhp at the fly.
Work out what power you want and its easier to find the way to it.

Ideally I'd like around the 150bhp if that's achievable with aftermarket ecu and throttle bodies

I assume its a silver top engine ? (silver / alloy cam cover - rather than the later black plastic one)
there were a couple of stock 130ps versions of the silver tops - these used more aggressive cams than the 105 or 115ps versions
so assuming your cams are similar to the 130ps spec (as this is the most common mod) 150bhp should be easily achievable on bike TB's - in fact
if that's all you got I'd be quite disappointed ! (burtons recon the stock manifolds are good for 150bhp with the right ECU)
but what you get is all dependant on the cams you've got any head work that's been done and how well the induction and exhaust is setup -
so with an unknown cam its anyone's guess what you'll get....

You will get better results with Jenveys, but your should get 160BHP on bike TBs depending on the size.
We did a stock blacktop on Jenveys and Megasquirt afew years ago......
http://baileyperformance.co.uk/?p=184
The exhaust is critical, big bore manifold and system is required for decent power

Ok that sounds like where I want to be so that's the route ill take just need to rebuild the whole thing now and see where my money is at once
I'm up and running ill do a rr session and see what I'm starting with then can work out realistically what's achievable as I 1st
said the guy who I bought the car off said it was out of a ginetta and didn't know if it had been played with and I've found uprated cams
so there could still be another surprise!
Thanks for all of the good advice and knowledge

Ok there's a megasquirt on ebay going the seller said they had been running a 2.0l turbo zetec on it its a v3 but ms1.
Would this be suitable to run my 1.8 zetec with gsxr 750 throttlebodies or do I definitely need ms2? If I do need ms2 can the megasquirt be upgraded
to ms2 by just changing the board?
