HBD not HSV. Holden by Design. A 195i engine is a HBD engine. Commodorenut will know more but from memory it gets cold air intake, knock sensor and a different memcal where the HSV vehicles have different valve springs on the roller cam engines plus modified exhaust. There used to be HSV enhanced Holdens earlier VN-VR etc but by VT it was HBD. I have a VS ute brochure here somewhere that shows the HBD 195i engine, later than VT (into VX) but similar timeframe.

I can't recall what Holdens had with exhaust, I know HSV were different. Commodorenut will know off the top of his head! I'm almost certain the cam is the same for the standard 179kW and enhanced 195kW engine, it is a roller cam.

hi the prefix on engine is vn------

have paper work from when it was new all numbers match eng num vn----- HBD PLATE BUILD NUM SDT 3274 BUT HSV HAS NO INFORMATION

I do not no I was looking at different site the difference between series 1 and series 2 they said motor main thing
different and clear blinker lights is this right any thing else different mine has clear blinkers

HBD was primarily just accessories done at the end of the main Elizabeth line IIRC, not a separate thing. Some stuff was done offsite like the panel van conversions done to utes, but the 195i stuff would probably have just been done on the main assembly line.

Roller cam is standard for all VT V8. A HBD engine option would all be done in the Holden assembly plant, nothing really to do with HSV. But it does appear by your car that a VT HBD engine is the same engine (with different valve springs and whatever else went with it) as a HSV by the engine number, would simply mean that it was fitted with this engine on the assembly plant line. The VS utes that have turned up with HBD 195i engines are the standard VS engine with the external mods. Probably as these engines were all stockpiled at the end of VT to be fitted into VS until sometime mid 2000 when they ran out of them.
