Currently I am replacing my pulsation damper (if I ever get the part ) and having taken my intake manifold off like 4-5 times now (dont ask why) I have lost some black small O rings (i'm pretty sure from the injectors but not possitive, but you get the idea somewhere from the bottom fuel rail, they just kept poping up ) from somewhere around there and the wires from 2 of the injectors have cracked, along with two of them have the plastic part that sits on the "injector" itself has broken and now fallen off, although they are still "going" I'm thinking of having them exchanged out for some new ones.

Along with this pulsation damper I had to fix the O ring from my intake manifold which was leaking/burning coolant <--fixed!! At the same time I ported my wastegate, seeing as to how I have a RB full blown expensive as hell exhaust sitting since, ahhh last year!! Now that I have been waiting and waiting for my pulsation damper order from 1987rx7guy for way way too long, I give up and decided i'm just going to buy a new one. During this "waiting" period my financial situation got much better and I feel like its well worth the investment to buy some inj's.

Now that that is settled for me, I would like to know as to how to go about it the right way. I want to not just get new inj's, but to rebuild my whole fuel system. For this, it means I need to start out with a new computer (right?), I will do some reasearch, but as always nothing is a good as getting the info from someone who was there and done it first. (No need to reinvent the wheel!) Your thought please would be greatly apprieciated, whats a good computer/injectors/fuel rails the basics, however first I would just like to get the blueprints into works.


P.S. If your reading this and your thinking to yourself, ahhh! another noobie, who doesnt know what he is doing, please your the one I need help from and although I am a noobie in cars I'm not in computers and when I come accross a thread like this on a computer forum I think the same thing however I just think to myself, pass it on! Thanks in advance.

My car is a 1987 rx7 s4 t II

ok.............

 

I think no one has responded because, though you have a lot of information, we still don't know what your plans are, or what kind of fuel you will need. From what I see you just have basic bolt-ons, so you won't need to upgrade your rail any time soon. Since you have limited mods, I would suggest you upgrade your secondary injectors to something like 680-750cc's. Upgrade your fuel pump to a walbro or whatever is your choice. With this extra flow, you should get a piggy back fuel controller. I reccomend the SAFC. Right now I, and my friends are using this setup. Once you get it all together, take it to a dyno and tune it, you will be a happy camper.
