I have a W reg late series 1 with the D4192T2 engine which is the less popular one. I think it was only fitted for about 18 months (1999 - 2000) so yours should be the later, more powerful & quieter engine. I think there were 2 power versions of the later engine, from memory I think they are 105 & 115 bhp (mine is a miserable 90 bhp !). There should be a sticker on the cam belt cover that should tell you what version of the engine it has. My oil filler cap is also in a different place than the one pictured. My engine was built by Renault. A search of the forums should be able to give you much more detailed info. I too changed from a Vauxhall, the drop of 60 bhp from my old Calibra has certainly slowed me down. Good luck with your potential purchase. Cheers
