i am removing my OMP pump i am buying the plate. i will leave the pump attached for now until i learn more about modding my ECU to stop it from going into limp mode. i am just wondering what needs to be done to the lines where the connect to the injectors?

Take them off.
Seriously, to do it properly you will need to pull the UIM and put plugs in place of the oil injectors, otherwise you will have a vacuum leak.

how do i do that?

Do you know how the system works? There is a pump that feeds oil to injectors on top of the LIM and on the housings. Each one sees vacuum, so any open hole (like a cut oil feed line) would cause a vacuum leak.
To get to the oil injectors you have to remove the basically the whole intake manifold (except the LIM). Get a haynes manual or look at the online FSM (links in the FAQ) for how to do this, and also to read up on the system.

You do know you need to premix one you remove the OMP, right?

yes i have read alot about premixing can u post a link where the manual is on how to take off my manifold? it is a 90 GXL

Its in the FAQs on the main 2nd gen tech page: https://www.rx7club.com/showthread.p...18#post5131218
Or you can buy a Haynes manual at the auto parts store.

Or you can use some common sense and just look at the manifold. Its really not hard to take it off. Seriously.

you'll need a R-Tek 1.0 chip for a 89-91 FC

GOGGIN

can u post a link to the pinapple racing video? that would be great

what year is it? s4 just take it out and plug the oil injector bungs. There are a few lines you need to run I think, I removed all of my emissions at the same time so I dont quite remember. I think on an s5 you need to leave something connected or get rtek.

it is a 90. and at the same time i would like to remove my cats. know anywere where i can get a catless. downpipe for cheap?

I have heard that without the OMP synthetic is ok.

I use synthetic with a still active OMP. Just make sure it's a good quality brand.
