2.4 di injector

[scas]

hi, my 90ps mk6 sort of died a few weeks ago, mad knocking ( dosent seem bottom endy ) and lots of smoke. i had a look at it yesterday and compression is fine, pulled rocker off everything seems fine. it may just be an injector. here in ireland itll cost about 100euros plus vat to get them tested and given the price of one injector new that seems silly. my question is, i also have a 2.4 mk6 115ps, are the injectors the same?. fordpartsuk.com only lists one for a direct injection but looking elsewhere it appears the 90/115/125 are different. anyone know the truth?
