Original eary-style injectors ('91 included) are highly prone to enthanol-related failure. There are several aftermarket brands, all with their own problems. The Nismo 740cc injectors are extremely reliable, hence everyone's recommendation. You will need a new ECU chip and associated socketing to support the larger injectors. You'll also need an adapter kit to mount the newer-style 740cc injectors. A call to Specialty Z will get you everything you need, including trustworthy advice. This solution will cost you more up-front, but is the least costly in the long run, and supports future mods. Replacing with stock 370cc injectors will just extend your cost incrementally and never solve the root problem.
