help needed 2wd cosworth engine

[classiccapri]

hi eeryone. i have a few problems in piping and wiring my engine up. need to know the answeres to these questions, if poss 1) thermostat housing has two outlets, where do these go? 2) where does the turbo oil feed come from? 3) could do with a full engine wiring diagram as i need to splice it in to my capri wiring loom. 4) which ecu do i need to use, i know i want a l8 for closed loop but i'm told i need a specific one with a lamba sensor? 5) cooling system again, using th sierra radiator i could do with a diagram of where hoses should go on the engine so i can pipe mine up, i have the expansion bottle from a cosworth? 6) the plugs on the engine loom are the colour of these mathced to where they should go or not? if any one could help me out with these questions, i'd be very grateful. all the best chris

1) thermostat housing has two outlets, where do these go?

1 goes to the bottom turbo water pipe, the second i dont think is needed as mine only has one so just blank it off.

2) where does the turbo oil feed come from?

comes from the inlet side of the block, on the end of the temp sender block thingy!!

5) cooling system again, using th sierra radiator i could do with a diagram of where hoses should go on the engine so i can pipe mine up, i have the expansion bottle from a cosworth?

Is the expansion bottle u got a 2wd or 4wd one?! not got pics but will try and sort something unless someone gets it up before i can!

6) the plugs on the engine loom are the colour of these mathced to where they should go or not?

Yes from memory they are!! just becareful as the ISCV one is similar too the injector ones and 1 can be mixed up!!

the other hole on the thermostat gose to the heater top pipe. if you have a standard intercooler goes from stat to intercooler, then out intercooler along pipe above exhaust into heater top pipe.

if you have a rs500 intercooler theres just a u-bend pipe striagt from stat to pipe above exhaust.

hope this helps.

escort only - not applicable to 2wd cooling systems

thats great people thank you.

i'm using the engine in my capri and am using the rs500 intercooler. so do i need to block the 2nd outlet off the thermostat completly?


not sure on where the expansion bottle came from actually, but if someone could give me some pics of the complete cooling system along with some pics if possible i would be grateful.

could also still do with some help on the ECU front?

thank you all again...

[jon@work]

Provided you're talking about the 2 8mm hose outlets, then yes you can blank one of them off.

re: ECU - if you're going to buy a L8, then the only difference between the red and green stickered ECUs is the chip, nothing else. If you're going to get the ECU chipped, then buy either ECU.

[classiccapri]

thank you everyone!! been a big help. could still do with a couple of diagrams of the complete cooling system and engine wiring if anyone has anything.

i have a 2WD loom will the L8 ecu fit on to this? if not what ECU do i need?

you mention a bottom turbo water pipe does the turbo have a water feed to it and a return to tank somewhere then also?

sorry to ask silly question but this is the first time i've ever seen one of these engines...

thanks again chris

2wd cooling system :

1 top of radiator to thermostat housing
2 bottom of radiator to water pump
3 bottom radiator hose T piece (in hose) to header tank
4 water pump 16mm hose to heater matrix
5 heater matrix to modine (oil cooler under oil filter)
6 modine towards the rear of the cylinder head (inlet manifold side) (separate bolt-on piece of ali with also containing water temp sender)
7 thermostat housing 8mm hose to turbo water feed (closest to head)
8 turbo to header tank

You can use the 2wd loom with a L1, L6 or L8 ECU (or even a P8) (but with a L8 or P8, you need to swap a couple of wires around)

If you get a L8 ECU, you also need a PF09 throttle position sensor (TPS)

[martysmartie]

Yes L8 will plug into existing loom but you need to switch the wires round on the TPS.

here u go mate, obviously if urs are standard hoses they will be black but didnt have a pic of standard hoses lol.

hope it helps

PS stat or thermostat should have been thermostat housing i was just being lazy

Seriously don't waste your money with closed loop, I have that feature on my aftermarket ecu emerald K3, but don't use it as if it is set up correctly/mapped isn't needed.
I can get 40mpg on a run no problem, best thing I ever did was ditch the L6, though it's not a bad ecu when live mapped, but all adds to cost, 3 maps on mine cost £280.

hi everyone,

thank you all very much.

with my cooling system i have got a mocal oil cooler fitted to the car so will be going straight from the heater matrix to the cylinder head.

whats this about a pipe across the rad?

i appreciate all this help

so your saying use the l8 ecu but not with closed loop?

i was also thinking of using wasted spark, so i can open up the spark plug gap more to stop the mis firing problems?

thanks chris

[Toe Knee]

basically across the bottom of a cossie rad u have a pipe like this one.....

[classiccapri]

so this is the header tank on the pass side of a cos? thats what this if for? if so i dont need one =]

again thank you for bothering to answer a stupid mans questions!!

chris

[tabetha]

Opening a plug gap is more likely to cause a misfire, cossies of 500bhp+ were running perfectly fine until coilpack came along, even though coilpack had NOTHING to do with performance!!
Coilpack came about due to cost, and lowering emissions, it does produce a stronger spark, of that's there's no doubt, but it was cheaper to make than a distributor and coil, it's better spark ability was excellent for the ever weakening mixtures forced by legislation.
In short don't assume it will stop a misfire, if it is not caused by a blown out spark due to seriously high boost it may well not do a thing for the misfire.
Personally I wouldn't bother with a L1/6/8 but it's your money, I went emerald K3 ecu, that does coilpack(or conventional) closed loop, or mapped position, which is what I use, unless you do a lot of motorway miles and have a chip/ecu that isn't as good as it could be you will likely not see anything you can measure.
Closed loop can be done on my ecu but when I get 40mpg on a run, not particularly easy there's no need, same as there's no need for closed loop imo.
Since changing from msd chip and L6, idle emissions for example are 0.97% CO, and just awsome the smoothness that comes with it, most adaptable ecu I have used.
My mapper emerald charges a set rate of £280 for mapping regardless of how long it takes, ecu was designed in house, made in house and mapped in house, by the most honest person I know.

thanksfor the advice, i'll look into the cost side of things.

can anyone say for definate if this is a l8 ecu?

thanks chris

[LHD220Turbo]

ask him what colour the screw is

[classiccapri]

thats wicked!

thank you very much
