318-325 questions and build so far

[j_tomo 0]

hey all

ive got a tidy wee 89 318 equiped with slushbox

and a 87 325 manual thats had a rather large smash in the teeth (the rest of it is up for grabs in the forsale section)

we all know the lil 1800's a bit lacking so im doing the big swap

ive got the motor, gearbox and everything else bolted up

the only hassels were the drive shaft center bearing has diferent hole spacings and installing the manual pedal box

ive just swaped the engine loom over, went to plug the ecu in and the lil 3 wire plug is different

now what do i do here? the wires arnt even the same colour

do i have to swap the dashes over?

im also a wee bit stuck on the radiator part

seing as my radiator was pushed around the viscouse fan its a bit useless

can i use a facelift type radiator with the overflow bottle on the side?

if anyones got a 325 radiator and or oilcooler send me a pm

thanks in advance

i cant wait to get it on the road!!!

have done the same....basically the easiest way to go about it (best IMO, but can be done others) is to convert the Pre FL motronic engine to FL motronic.

basically this involves off the top of my head:

engine loom (inc sensors on the front crankshaft pulley and RPM on ignition wire)

front cambelt cover

front crankshaft pulley

this includes facelift cooling system:

hose that leads to expansion tank

expansion tank

radiator

hoses to radiator

FL waterpump (may as well do cambelt while ya there)

it sound a bit much but makes it easier in the long run, as everything is facelift and matches...i may have forgotten a couple of things so i could double check before ya went ahead and did it. is easiest to have a complete FL to take bits from really.

only other way i could think of would be to use all Pre FL stuff and make an adaptor to convert the car wiring loom to work with the engine wiring loom. things like hoses etc usually need doing anyway so it makes sense

ohhhh i dont want to be buying more stuff lol

can i just cut and join the 3pin plug that goes from the key (im guesing) and into the wiring loom just to get it running?

thanks

Two of the wires are just outputs for the dash (tach and fuel economy) The other signals the ECU to switch on.

well its a bit hard seing in the dark with a cellphone light but coming of the 325 loom i have green, black with blue stripe and a white on the 318 loom i have a green, purple and a brown

thanks

Connecting the two greens together should get it running. Once you have the engine running just take a stab in the dark with one of the others, if you get a nonsense reading from the tacho or fuel economy meter- you guessed wrong. I doubt it will do any damage.

had it running today!!!!!!!!!!!!

turns out i had the fuel lines around the wrong way

ya get that when you have to install a motor that you didnt remove

anyway now im just looking at the radiator section

i want to use a later modle set up so i dont need the ugly overflow bottle

so who can sell me a radiator and bits?

thanks
