Vivaspeed's 1969 HB Viva racing type car
Posted 11 February 2011 - 09:08 PM
Let me give you a brief history.
While building a 4AGE Starlet in the beginning of last decade (some time around 2001-2002) I saw a very quick and interesting supercharged HB Viva at Ruapuna. First thoughts were "why a Viva..." - I thought that was cool and did some research - it has been downhill ever since...
Take one $500 Viva with a 'worked' 1256cc, Weber 28/32 DCD carb and extractors, big bus wheel and Hillman Hunter seats. Went okay until one day it didn't - couldn't be bothered investigating so out came the old engine and it lived in the garden for a while.
Add one $200 1800cc Magnum front brakes, crossmember motor and diff, a dirty old Link EMX running a mitsi single point injection unit and a nice new cage that I got in exchange for a 3SGE motor.
I took that contraption to the track and had some slow fun, on a good run it would rev to at least 5000 but not happily. It was a bit front heavy and tended to oversteer in the wet. It was like this for a couple of years.
Then it rusted, and the engine was crap so I pulled it apart, cut a big hole and put a better engine in it. That process took some 4-5 years.
I painted it myself in the depths of winter when the steel was a bit cold (I'm an electrical engineer, not a tradesman painter, so can you imagine the quality???) and put it back together. Strangely I still had all of the parts despite moving several times.
Since then it's been to Taupo a few times, done some club events, and most recently Manfield in the wet.
For those who like to get carried away with details, it's got the following bits inside:
Toytoa 4AGE smallport with std ECU
W57 gearbox and Niteparts bellhousing
Escort 'English' diff
Magnum 1800 brakes front and rear
Princess 4-pots (Front)
Fibreglass bonnet, boot, bumpers and patches in many little rust areas
Cage, seats, harnesses, and all the lovely safety stuff
Sits on 15" minilites with Dunlop Direzza targa/DOT legal tyres.
Lots of 'custom' stuff made in my shed
Many bits from pick-a-part.
Lots of mods coming up now I've got some decent workshop space again.

A GT type grill - had to paint the area behind it matt black to make it look right, and also cut some space to fit an oil cooler behind it.
I somehow suspect the car won't go any faster with this, but it does look good...
...and something that will make the car go faster, not from Trademe but something a mate built and I picked up at a favourable rate. It's a small port, got some ground cams, adjustable cam gears and is a nice fresh new motor. It will soon take the place of the tired old wrecker motor I've currently got doing the job.

Made a start, pulled the old 4AGE out to make some space (and to give the workshop floor a nice oily, damp texture).
Swapped over the relevant parts to the new engine, with many problems - first the knock sensor fell apart due to being brittle so a Pick A Part tripped followed - $4 and a greasy arm later we were back in business. Then the usual things not coming apart easily, not going together properly, etc
Then the dizzy wouldn't fit because of a stupid bushing the last owner used with his 4K dizzy. I got frustrated and went home. I have 5 weeks to get it going... no rush.

While uploading photos I thought I would also give an update on my diff...
Bought a Quaife ATB from the UK, and a 4.7 ratio CWP from Burton Power and had them fitted into a diff head at Howat's, then fitted it to the car. Makes a huge difference compared with the old 4.4 locked diff I had.
