looking for an answer on whihc kit would be the best for a 89 supra 7MGTE..i was debating on putting a zex kit on there , but didnt know if for my car a shot would be better then zex.. and the difference between wet and dry kits im kinda confused on and trying to be come more car literate.
thanks

dry shot(zex) means you spray plain nitrous thru the intake manifold, and enrichen the fuel side up, through spraying nitrous into the fuel pressure regulator, not only does this enrichen the fuel injectors but has your pump jump to max efficiency.

and a wet kit just spray fuel and nitrous thru the same nozzle via regular silonoids
