OMP sensor modification for Top Mount Turbo & SOHN adapter.

Recently I installed a SOHN adapter and an SFR Turbo Kit. The problem with these two coexisting is the OMP sensor plug, gets in the way of the exhaust pipe. In order for me to get them both installed was to modify the OMP sensor and install it upside-down (cables towards the top.) I cut the plug off the sensor leaving the 3 pins exposed (you only use the 2 outer pins.) I then soldered a wire on each long enough to reach through the back of the adapter so the cables did not touch the exhaust and bend them inward (towards the motor.) Then I covered the entire OMP section, including the SOHN adapter and hose with high-temp resistant fabric sold @ Adavced Discount AP. On mine I went the extra mile and from a 2nd sensor I added the plug at the end of the cables so I didn't splice the stock plug from the wiring harness. Here is a pic of my modified sensor:

its hard to tell from the pics though. try using your flash and a different background.

I didn't have a camera at the shop, this was using a phone ! :O

Idea is to use what used to be the top of the sensor at the bottom, occupying less space. And in order to do this you have to cut off the plastic part of the plug, then bending the pins towards the motor and soldering wires to it and of course shielding it afterwards.

I already installed everything (water outlets & hoses) you wont see much, but I will take pics tomorrow AM, all you will prob. see is the covered OMP with high-temp fabric and exhaust right next to it...

I don't know of any other provider for the SOHN adapter. I got it from him (or his company don't know who I emailed...)

2-stroke oil canister I used... (center one, right one is Oil Catch and left is still on the works for the windshield washer fluid, need to make adapter for pump.) Still have room for a 4th one Maybe a radiator reservoir?



Only pics I took when I installed turbo: http://xtreme-toyz.net/sfr-turbo

Do you know where he got those tanks? I like that a lot actually.

I was asking where the adjuster goes because if it goes in between then there is no space for all 3 (sensor, adapter and adjuster) The adjuster is supposed to set the OMP to a fixed amount of oil injection used for aviation (renesis at high rpm all the time)

Yes it is but adapting it isnt the easiest.

I have a trio set that is already adapted to work with windshield reservoir

I am looking for the Mazsport radiator reservoir. I would like to remove the ugly white plastic one from the from since I relocated the battery to the back and added 2nd terminals for 2 batteries instead of 1.

its not needed. if you have the AP you can adjust you OMP output that way. the adapter allows you to inject 2-stroke, the adjuster allows you to alter how much oil you are injecting

It has a groove all you do is turn it up-side down and it works the same. I tested it on my own car, worked flawlessly. I now need to premix, installing a 20B on my car now...

What I did was took both screws off. Noticed how much winding it had, turned it around 180 degrees with same windings where the groove snapped in, then put back the screws. Car never threw CEL, smoked a little like before and the oil consumption stayed the same.
