Hi Rick,

I also have a HZJ78R Troopy 2002 vintage. Manual, 5 speed, naturally aspirated (non-turbo) and using those gears wisely will pull me anywhere. Of course the turbo's will go faster on the highway but I never seem to have difficulty reaching the speed limit. Does slow down a bit on the hills though.

I'm sure I'll get argument with this but it seems to me that the simpler it is then the more reliable it is. Turbo's do have their problems at times and out-bush the less there is to go wrong the better in my book.

Thanks all, especially Stu & "Bob". I think I have an working understanding now.

Next Q:

Is it worth paying approximately $8 to $10,000 more for a 2nd hand V8 over a turbo-ed 6 cylinder?

I realise age, condition & mileage affect price also; but it's not hard to find vehicles of similar age/km with a $ 10 K difference. Is this just due to the V8 alone?

Cheers

Gday Rick,
Sounds like you now know the designations.
Knowing what you do and where you go, I'd suggest you go for the HDJ78.

The HZJ78 is a bit of a slug and uses more fuel - about 13.6 l/100k vs 11.9 l/100k according to the official figures. The VDJ78 has had its teething problems with oil consumption and fancy injectors.

The HDJ78 uses the 1HD-FTE 24valve factory TD motor which has been around for a long time, and is a reliable piece of gear. If you ever want more power, you can add a chip (eg Dtronic) and 3" exhaust, or if you're satisfied with the torque, you do nothing!

The HDJ78 came in 3 versions according to seating. Released in late 2001 and finished at the end of 2006. The 3 seater and 11 seater vehicles were base models with vinyl, 3 seats across the front, windup windows, no central locking, cassette player etc etc All troopies came with split rims, but if you want tubeless rims, any of the rigid axle 105series will fit, but you'll need to buy flares.

The 5-seater HDJ78 was called the RV - came with carpet, small centre console, twin bucket cloth seats, bits of chrome, CD, electric windows, remote central locking. Its probably the most popular model and commands a few more $$.

The SA Govt Auctions is a reasonable place to buy. But check the service books and try to trace the past history. Most are sold with 100,000k on the clock and sell for $30k to $43k. The cheap ones have usually seen heavy use up north, the police ones look to me to be better serviced. A lot of the accessories were taken off them before sale. If you buy oine, you'll want to fully service it before going too far off the beaten track.

Cheers
Phil

We have been travelling with our 93 Troopy since 2007 and have done over 75,000km with it. Wouldn't have any other vehicle. Our only comment would be check for rust, especially in the roof and around the gutter, and windows.
