Hey guys,

need some help from someone with some experience. I am about to buy 2JZ IS300 injectors off a fellow toyotanation member, and I was curious about the fitment on the 97 1MZ's...If it is a direct fitment, I have an A'Pexi SAFC-II to control the A/F ratio, along with a wideband A/F and I am already getting really good numbers in terms of CFM (dont remember what they were exactly, but they were above stock - I am using a 4.6L intake filter... .5% resistance on air flow on the total system). If I upgrade the injectors, do I absolutely NEED to turbo it or anything, or if I control the A/F through the SAFC, can I upgrade the injectors, without any other fuel management mods? keep in mind that this motor will eventually be turbo'ed, so ill need the injectors sooner or later.

Don't buy them,,, The IS300 injectors are not the same as the Supra NA injectors. IS300 comes with 290cc/min stock, which is actually nearly the same size as the stock 1MZ-FE ones, if not, smaller...

As for fitment, they don't fit too well either because the seals on the intake manifold side look different compared to the 1MZ-FE ones as I recalled.

Hope you see this reply in time... DON'T get those injectors!
