I think you asked the right way lol. All you need is this: adaptor kit. It's an adaptor kit that includes everything you need. Also, you need to grind down the front passenger side of the manifold to fit the injector connector, you probably know this from my past thread though. Be sure to get them cleaned (~$120) if you buy used ones to make sure they are up to par. Let me know if you have any other questions.

Hey how is it going im new to this thing so im not sure how this works but i saw in one of your posts that you put in some new style injectors on your 90 300ZX. Well i have a 91 300ZX and im trying to replace my injectors as well and i want to put in the newer style injectors the one with the oval connection, i dont like the connection of the old square ones the ones that require the the clip.. Well my question is would the new style injectors 93-96 fit without any modifications besides the new injector connectors i will need to get to fit the new injectors. I figured since you already did this that you could give me some advice... and im sorry if im going about asking my question the wrong way im new to this. any advice i would greatly appreciate
Thanks
