No worries, i have a 84 sierra swb with the 81 front end on it,(coz i like the jeep look) i canned the gutless 1.3 litre engine and went for the biggest i could fit in the engine bay, izuzu 2 litre out of a holden gemini followed by a gemini 5 speed box which is all up is 700mm longer than the origional engine and box, so i had to push transfer case back 300mm and fabricate custom driveshafts and mounts.
I have sprayd her acrylic jet black for that mean look and know she is the quickest 4x4 around.
I also am using big jetted webber and performance exhaust with extractors.
Soon i will get twin webbers as i want 100+ hp out of this engine which will be easy.
I see your zuke is a pretty mean machine, i would like to raise her more and put some of those huge tyres on it.
