i have a 1988 rx7 and i was wondering if i can remove the oil injectors that are in the lower intake manifold and block

 

Only if you plan on premixing 2-stroke oil into your gas. Premixing is very common, but somewhat of a hassle every time you fill up.

 

what???? rotarys are 2-strokes????

 

so how does this work does the oil from the engine go thru the pump and get pumped into the manifold and mix?

 

exactly. The OMP pumps oil from the engine into the manifold, this keeps the seals from going out. Oil is also important for engine compression, the oil seals the apex and side seals giving you good compression. There are kits available to allow you to feed the OMP from a separate resevoir that can be filled with 2 stroke oil, as apposed to mixing it in with the gas.

A rotary engine is like a 2 stroke, allthough the analogy is a little thin as without pistons there really isn't a stroke. But basically it does not have valves, but instead gas and exhaust use ports to access the combustion chamber.

 

ok cool well i think i will just leave the injectors in and run it like it is thank you

 

I have the OMP system intact and also premix approximately 0.25 quarts per whole tank... Is it good or bad?

 

A little extra oil won't hurt, but you might find the car start to smoke if you add too much.

 

Thanx a lot!

 

if i remove the injectors from the manifold but leave the injectors in the block would it be ok or would i need to mix the gas with oil?

 

Your seals will get half the oil they require then... Leave it as is.
Why would you like to remove them anyway?

 

No. But the only way to lubricate the apex, corner and side seals is to introduce a little oil into the air/fuel charge, which is then burned.

This is unlike a two stroke where the oiled A/F mixture is also used to lubricate the crankshaft, connecting rod, main bearings, etc. The rotary has a fairly typical oiling system consisting of a sump and oil pump that circulates oil through passages in the block and eccentric shaft to lubricate the rest of the engine. Just a tiny bit of this oil is diverted and delivered to the intake manifold and friction surface of the rotor housings through a metering oil pump and set of nozzles.

 

thank you very much aaron cake thats what i originaly thought the injectors were for but the thing that i was getting from people is that it was for oiling the seals and the engine needed it in the fuel to run thats why i thought it was a 2-stroke. . . . . one more thing does my engine have 4 fuel injectors? 2 in the manifold and 2 in the block?

 

guys i am totally new here i have one of 2 fd's in the country, previously my car was a toyota trueno, bought the fd because i wanted to learn more about cars and specially the rotary engine. yes i am using mineral based engine oil, 20w-50 Total 5000 engine oil..

i would like to know that for premixing do i pour the same oil into the gas tank or is it that i have to buy oils that are used in bikes i.e two stroke oils.. is there any difference please clear my confusion..

sorry if i couldnt explain what i tried to say

 

You could do either but most people use two-stroke oil. Burns better.

 

There are 4 oil nozzles. One in each rotor housing which lubricates the apex seals directly, and one in each primary intake runner on the intake manifold to introduce oil into the air stream.

 

is there any thing such and better oil injectors.. or a way that we can clean them???

 

There are no upgrades.

You can clean them with carb cleaner, but you need to remove them first which means pulling the upper intake. At the same time, you should replace the oil lines from the metering oil pump.
