Title: Moving bits over from an ABD to AEX
Post by: Ashley on 14 October 2009, 14:04: Hey

I've got an ABD 1.4 Single point injection, been offered a recently refurbed AEX and been assured all of my junk will transfer over, i.e throttle body, injector, dizzy and ancillaries etc if i just use the head/bottom end

also wondering about ECUs? will this work too?

is this the case? they look very similar but just want to make sure im not going to buy something i cant make use of

cheers

Ash

Post by: adamrob69 on 14 October 2009, 17:23: you will need the ECU because its a different injection system. so it will need coding, or you will need igntion and door locks etc

you will need the throttle body, possibly the air intake system also, injectors, not sure on fuel pump, i would imagine it would be the same, the wiring may need changing aswel as the sensors may be different.

Theres quite alot of work really for what it is. and that is presuming that all the parts fit (the blocks look the same but that doesnt mean that it has the right mounting points or whatever), but it should be do-able if you have the time.

Also the difference isnt that great between the engines to go splashing money out. the aex responds and revs better, and it will have slightly better torque (slightly) but its still as slow as the abd

Post by: Ashley on 14 October 2009, 21:25: i wouldnt be swapping it to gain any power, it's just the fact this engines had work done to it and it's cheap, plus the fact i think mines giving up the ghost soon

so basically it may or may not work, and if it does its going to require abit of tweaking here and there and the odd part

cheers for the advice

Post by: adamrob69 on 15 October 2009, 13:07: so you want to swap your ABD engine, to the AEX? if so i would change all the injection systems to the AEX system, will need the ECU locks etc.

If your on about converting your ABD block to have the AEX injection system, im sure its do-able, but you need to weigh up if its worth it!

Post by: Ashley on 15 October 2009, 17:14: was just going to use the AEX head and bottom end, then move over all my injector, throttle dizzy etc over, but i've decided it's just not worth buggering round with the ECUs etc, it's almost a conversion for all the effort i'd have to put into it

if you are planing on just changing the engine, replacing your ABD with the AEX blocks then you wont need an ECU or anything as your using your existing injection system. Try looking on a mk3/4 polo site as they had the same engines and will probably have more information on what you want.
