Hey dude dont have an injection system, hit up auto dismantalers or junk yards. should find one, ever thought of putting a larger and more performance inclined carby? dont really know those engines tho. we have been looking for over 2 years but cant find any, we are running 40mm dalauto carbys on it. even if we can get 40mm or 45 mm webbers we would be right but even there hard to find cheap. we have had it on the dyno 3 times, it will be great for a day but then it will go back to the way it was. when we had a datsun in it we had 45mm webbers but sold the for $500 & the engine for $450.
