St170 fuel injection on a budget project.

[big_wasa]

Yeh the ports are around 10mm higher on the st.

The fuel pump should be better for carb upgrades as no return will be needed.

The exhaust is a 4-2-1 design and I know a few have reworked it to fit a kit so no adjusting will be needed.

Yes there is some working out todo, but I enjoy the engine managment side of things.

It will run better all round than any megasquirt can be tuned to do.

there are some squirted 2l zetecs pushing over 190bhp on all std internals now

[big_wasa]

They must be generous rollers as the big tuners only get 165ish with out cams and headwork. I would still question if it will idle like factory and meet an age related emmisions test.

At what price for Ms ? Mtec want £600 for there Ms with a bit of time on the rollers. I havnt looked at uk prices of a proper Ms for a while.

I have installed Omex, Ae, Dta ect on engines, mine and others inclueding a guy that builds busa engines for radical.
They all start at that sort of money PLUS time on the rollers.
I know of a few people that have had multi sessions on the rollers each came away with max power from the start but keep going back to tweek it for around town.

The point of this post is best power for a budget. My ecu cost less than the going rate of an edis4, £29.99 and wont need time on the rollers.

i totaly understand the cheapness and possible fun of what your doing but in my opinion it just needs to be ajustable to suit inlet and exhaust changes needed to fit into a 7 kit also i looked into useing a st170 motor but there is to much in the way of twiddley bits making it an over copmlicated install and i would of had to buy a complete car to get everyting i would need

all boils back to the age old well troden zetec stripped back and aftermarket ecu, exhaust and some form of good inlet

my friend has a sylva striker with a 2l zetec he squirted himself on bike throttle bodies and it was eating type9's even ate a club one
from too much power
had to tone it down come the end and it would pass a cat test come mot time

Right behind you on this one Wasa. Please let me know how you get on as Ive been thinking of replacing my Pinto with a Zetec/ ST170 but would only be prepared to go for it if i could use the fuel injection system and ECU.

Getting hold of the right engine, modding the sump, moving the exhaust to the other side of the car - that all sounds quite enough bother and cost without having to tinker around and spend hundreds on bespoke manifolds, setting up bike carbs and rolling road sessions as at that point I'd be better off putting a Cosworth head on the Pinto.

[snapper]

Cosworth head on a Pinto is a BIG job
Pistons no cheap way out
Cam belt crank pully, the cossy crank is longer and the pully smaller will need to machine to fit a Pinto crank
I would question cost saving over an injected Zetec
All interesting this thread, the Ford ECU whatever version is always difficult to break into, I have a friend who can using Ford software to get very deep into it but every instalation would need him at the rolling road.
Megasquirt has been proven but I find it a leap to far for me, price though is competitive and we have picked them up under £200
There will always be a limit on how much you an squeeze out of a standard engine, the ST170 never made 170bhp.
I watch with interest

[locost-turbo]

any updates? how did u get on in the end. is standard st170 possible on a budget?

[big_wasa]

yes mate there is a couple of vids of it running at the end of my project post.

here is one

Dynos on drugs 200hp zetecs cost between 3k and 5k if they are built properly, someone best phone up the tuning boys and tell them about mega sqiff . Keep going at it Wasa its the way to go. Shame these cars arn`t like the old range rover with a complete stand alone ecu and wiring system. All it did was pick up a couple of wires on its way past the ignition switch.

I allready do the Mondeo zetec ecu's silver and black top.
The mondeo engine loom is almost self contained. If you could fit it in the engine bay there would only be one 42 pin plug to wire up and only around half the plug is used. These are good for around 150bhp

The st170 gets more advanced and more complicated. The extra tunning needs extra controle.

On top of the blacktop stuff...
you have.

barametric sensor
vairable inlet
vairable valve timming
returnless fuel pump controler and pressure sensors.
pre and post o2 sensors.

The ecu also hooks into all sorts inclueding the clock

If I can do this then I can do the RS loom.
