difference between asz and arl engines

Hi I've got a bora with a appitite for cams last one lasted 19k. Was going to replace the full engine but findinding it hard to get a arl with. A decent milage for under 1k. Was wondering if a asz would fit using my turbo and ancillaries and what's the main diffenecebetween the 2 engines

The only physical difference between an ASZ and an ARL is the pistons which are stronger on the ARL.

Cheers do you think it'll run right with a 150 ecu and turbo

The head and injectors are identical so there is no reason why not. In my opinion, ARL engines eat their cams due to the loadings placed on the oil by the turbo so just swapping the engine will not make any difference. What make of cams have you been using and which oil?

Its a genuine vw cam and always use vw oil. The cars completely standard the first cam went at 142k and this one 161k. Its in vw at min getting checked out on there 2 year warrenty ont the cam. Is it wort keeping the car or just get it running and part. Ex it

It would be interesting to know if it has failed on a valve or injector eccentric.

hopefully vw tell me what it is tomorrow, when the original cam went the vacumn fuel pump had a lobe snapped off where it goes into the cam, therechecking itunder the 2 year warrenty so they'll do anythiung not to payout

Its been in to vw and they diagnosed it as a faulty cam so they are replacing the cam lifters bearings on the warrenty

Got car back for vw dealers feels like a complete different car compared to what it was like the turbo seems to be working much better witch last time it would be no power up till it 2200rpm and now pulling from 1200rpm. And starts better and quieter. Vw did not give reason that cam failed but there was wear on all lobes but ainly the 4th were it had wore all the tip off. What they did say the last garage put none vw lifters in could this be why it drove like a bag aof **** or something to do with timing. Cheers
