No they're all ve engines, the previous version to the PD, I got the complete injectors and sent them off to get the new nozzles fitted. The problem is that the tdi injectors are 2 stage and are different to set up, they have to fire a short initial burst then the main spray and it's all mechanical so need specialist equipment to do them right. If you keep an eye on that tdi site, kerma often does special deals so I got mine for $249/£160 ish. The 764's are around .232, the T4 ones you're on about are .216 but the 1019 or whatever they are are just slightly bigger and worth getting if they're on special or the PP 520's. The race ones or stage 2 ones aren't worth bothering with unless you're going nuts with tuning.
