for those that doint know, Vauxhall Viva was the pommy car that holden turn into the torana. but because of that Australia missed out on a great car.
The Viva came with a slant 61 deg 4 banger, same as a bedford van. BG 4 speed gearbox Salisbury diff. available in 1.6 1.8 2.0 2.2 and 2.3. there was a 1.2 but that was a different motor, still raced in the chevetts with great success rallying.
the 61 deg, change pistons, re grind the cam, heaters and a couple of 45mm Webber's lighten the fly wheel = 180hp old money in the 2.3, done in the back yard. do it in the shop 200 was quite easy. and the viva original shell was quite a bit lighter than the torana.
its the same block that was originally used by lotus up untill thay fitted the V8. so 2.3 slant 4 turbo = 350 hp that was in 1990, road trim 290 hp
NB thats british HP not Jap HP
