I got a jdm engine. Its an s5 and my car is an s4. I figured the fastest cheapest way is to go premix. I dont feel like swapping mechanical oil metering system because i would also need the s4 manifolds... I like the s5 manis better neways.


Is it 100% ok- to just leave the electronic OMP and oil injectors in their stock location and just premix?

 

S5 OMP won't work in an S4 car anyway, why not just block it off?

 

Sure. You'll burn both crankcase & premix oil, but who cares? I've done this with 2 of my 3 fc's. Check your spark plugs for fouling every 500-1000 miles & be happy

^^ im not going to use the OMP at all.? OR does it still shoot a little bit of oil even though it wont be controlled by anything? Im asking if it is ok to just leave the OMP there without function and use premix.


ANd i would block it off but i dont have time for parts to arrive.

 

As far as I know, the S5 OMPs don't function at all if they aren't plugged in to anything. So you'd probably be fine just leaving it there if you're in a hurry.
