Put a worked a14 or a15 in it, keep it mostly original looking but really tidy and it will always go up in value and always be a classic if you look after it... makes me to see all the dattos in the world being cut up to put these bigger engines in them... but I guess it just makes the ones that will be left in 20 years time that much better....

carby all the way, it is such a great sound that gives it that datsun uniqueness. Worked A15 is the way to go... get so much power out of em if you tune them right.
