j_tomo 0 Report post Posted September 16, 2006 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!!! jeremy Quote Share this post Link to post Share on other sites
Gus 5 Report post Posted September 16, 2006 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 Quote Share this post Link to post Share on other sites

gmccormack 0 Report post Posted September 19, 2006 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. Quote Share this post Link to post Share on other sites
