I think it is me you are refering too!
Firstly I said Non turbo KB laser carbies are the same as 1200 and so on ( just a later version " Hitachi" )
Never seen a factory Turbo KB laser but asuming they have the same carbie this will have relivence!
( I do know of a non turbo kb laser which was turbo charged but because of the boost pressures it ran it to needed the carbie to be modified for boost!)
We found near or over 15psi boost for either laser or datsun carbies required them to be modified for boost!

Also this turboed lazer had a datsun carbie throtle plate ( the throttle body of the carbie!) fitted to it as lasers only had vacuum secondaries!( maybe some lasers do have mechanical secondaries! but I am not sure!)

Anyway I fitted a kb laser carbie to a N/A 1200 as the datsun carbie was Rooted and the KB is all we had around at the time!

I will post a pic today of the mods required to fit it to the datsun manifold!
I will put it under " forum" "Carbie base Plate"
