1.6 to 1.8

hi all new 2 sight just need a little help ive got a 1.6 1995 escort but also have a 1997 1.8 engine fully rebuilt the trouble is the injector wires are a different colour on the multi plug does this make a difference if i plug them into my existing plug also will the pats be a problem with the new ECU Ive read the bumf on the 2.0 very good info hope u can help

Welcome to the site

Im pretty sure dave knows about this, He Is one of the Moderators to this site, and he checks in dailey, So it shouldnt be too long before you get some help mate

thats what im hoping god that chap has got his head on tight its so hard to find good tech info these days

i put a 1.8 engine into my 1.6 mexico and just plugged everything in, started and ran great first time

cheers dan i was getting worried I .know I have to change the air temp plug and the reverse switch plug bloody ford wires.I take it the PATS is built int car then so no need to change keys ya who

yeah if your running on your 1.6 ecu then the pats wont be a problem

i run, 1.8 engine, 1.8 throttle body, 1.8 maf, 1.6 ecu, 1.6 inlet manifold, runs great

Ive got the 1.8 ECU and the keys inc the red key will i need to use them if i fit the 1.8 ECU

yeah you will, what you can do if you dont fancy changing your locks is tape the 1.8 key to the sensor behind the steering column and then just use your own keys and locks

heres mine, i used an RS turbo crossover pipe too

my 1.6 is efi like yours the 1.8 doent have that manifold which is a shame cos i like the efi manifold

you can use it, just swap it over, thats what i did

cheers buddy chat again soon

Good afternoon, Welcome to ford-force.

To be honest, there is not much i can add to what dan has already mentiond.

For a trouble free instalation use everthing fitted to your 1.6 engine, manifolds, gearbox, exhaust etc.

Just swap the bare 1.6 engine for the bare 1.8 engine and fit the ancileries back up.

Get the engine swapped over and running on the 1.6 ECU, It will run ok on the 1.6 ECU just it wont relase the full potential of the 1.8.

I would recomend staying with the alloy inlet manifold as it avoids messing with air temp sensor wiring.
Just fit the XR3i 130 or RS1800 fiesta Throttle body as the 1.6 Throttle body (and 105ps 1.8 throttle body) are restrictive.

As for the ECU, plug and play, just as Dan said... you will need to keep the red key near to the PATS transciever ring around the ignition barrel.. taping it to the ignition barrel (under the steering wheel columb covers) would work but effectively leaves your car without an imobiliser.
What you "SHOULD" be able to do as you have the RED key is to allow the 1.8 ECU to accept your 1.6 Keys.
Wrap the 1.6 igniton key in foil so the RED chip is concealed.
Hold the RED master 1.8 key near the PATS transponder unit (by the ignition barrel),

Turn the ignition to II, The imobiliser light will illuminate.
Turn the ingition off and remove the key.
The Imobilser light will go out
The imobiliser light will illuminate again for approximately 2 seconds
Once the light goes out You have 10 seconds to unwrap the foil from the 1.6 ignition key and insert it in the ignition barrel and turn to position II.
The imobiliser light will illiuminate again to inform you of successful programming.

thats not true... it was to do with delivery, you can run 150+bhp n/a on the 1.6 tb

what dan and dave have said is all very helpful information. we're assuming you have external pats not internal pats

james i ran the 1.6 TB on my 1.8 and it was gutless after 4k, changed ir for the 1.8 one and its sweet

Yeah, but to get 150hp with a 1.6 35mm throttle body is hard work, at that stage the TB will be a large restriction.

no the inlet manifold is.

Hi dave cheers for the info. The 1.8 is fully built inc gear box all the throttle injectors ect. I even have the transponder PATS.Therefor I wish to use the 1.8 ECU now the wires are different from the 1.8 transponder 97 to the 1.6 /1995 even if you follow the wires to plugs there different . they both have 4 wires at the transponder 1995 are coloured 1997 are black plus different plugs if the key idea doesnt work can I get around the pats I have a thatchem 1 alarm so no PATS wont matter.Also the cold air senser how can I reconect if I use the 1.8 engine as it stands to save to much messing about.

oh what it is

My cold air senser 1995 mod is wired into the larger of the 2 multi plugs the wires are the same colour and the violet / white still end at the ECU at pin 35 as discribed in haynes. The air senser OFF the 1.8 1997 goes all the way to the ECU on its own in violet / white: the brown joins the others half way down the loom.Why cant I just wire the senser to the 1.8 senser .or can I? ;)ILL stick with the 1.8 tb as its new.The EFI alloy unit is on the 1.6 sorry i forgot to mention that hence the reason i dont want to put it on the 1.8.

i think you'll have to speak to dave about this one mate, hes good with all this pats stuff

13mm and 10mm is all you need to remove the inlet manifold from the head.

Fit the silver alloy manifold to the new engine and theres no messing about... its like for like.

As for the ecu... swap the 1.6 and 1.8 ecu like for like, wrap the 1.6 key in foil, hold the red 1.8 key by the ignition barrel and see if it starts.

ive just been on ebay the TBs are thin on the ground is there another way to wire up the cold air senser
