OK, I'm thinking about getting one. My only question is this - when boosted, what will the oil pressure range be?

Or to be more specific, should I get the gauge that goes up to 100 or up to 200?

 

I asked Boe a similar question a while ago because the VDO white faced gauges only go up to 80psi. He said it would be fine, but it might spike during hard boosting. If you get the gauge for 100 you should be fine. The EVO guys spike the 100psi gauges under heavy boost as well.

 

Also, you might want to go with a fitting like this, so you can run your oil line for the turbo kit and oil pressure gauge off of the same adapter fitting.

 

Where do you set up the probe??? Tap the oil pan? Or get a 90 degree plug? Greddy adapter? What's the best choice?

 

When you go with the turbo kit from RRM (might be true with the others), the oil feed line comes off of a 3/8 NPT bolt that sits above the oil fliter.

#1: You can use the adapter I have linked above
#2: Splice some fittings into the feed line furthur up
#3: Take off the stock oil pressure switch and use yours (you'll get an annoying light in your dash board)
#4: Using adapter fittings, put a feed line at the stock location, run it to a T fitting, and put in both stock and aftermarket pressure senders.

I've heard the Greddy adapter isn't a good idea for our cars, because of the configuration of the oil filter. It would force the oil filter down about an inch or so, which would run risk of hitting the ground over large bumps or speed bumps.

 

Well, since I just bought the Greddy adapter, I guess I'll let you know.

I don't anticipate a problem, though. Even with the lowered filter, I'd guess that if you bottomed the car out that much, you'd scrape everything down there. But I may just get that fitting when I go turbo. Sounds easier.

Thanks for the info. I'll give the 100 psi gauge a shot.

 

I found few fitting adapters for like $10.00 and it looks like it goes where the drain plug is.

The oil drain and the oil pan are not pressurized. The drain is gravity fed. The pan is just the pan. You need it on the high pressure side. I just happen to have that exact fitting that lively linked to (for my FP gauge when I change my fuel lines in the future), but I don't know the proper -AN for anything or even how to determine what size fitting you'd need.

 

I updated my post above, since tapping the pan isn't an option. The fitting you would need if you are doing option #1 is a 3/8NPT to -6AN adapter. The RRM kit uses -6 lines if I remember correctly, and the plug used by the kit is 3/8NPT.

 

But where I would use the fitting with N/A setup?

 

You can't. I'll find a fitting you'll be able to use, hold on. To be honest, option #4 would probably be your best bet. It's not very safe to hang the sending unit off of a fitting, especially if the fitting is brass. The fittings I linked to might not cause an issue because they are aluminum, but it still isn't the safest way to go. The safest way is to mount the sending unit somewhere on the frame, and run an oil line from the unit to the engine.

 

Here is one solution, but these fittings are brass, so it's not wise to mount the unit right to the fitting. The brass will eventually leak and break.

Here is another option that is aluminum, but you might have issues fitting the sending unit right to it, which is why 42DD (the link above) did the 45 degree angle fitting.

Since my engine is empty of oil and coolant, I'm going to take out and measure the stock oil pressure sensor. I'll see what size it is, because there are adapters that should fit so you can run a line, T, and connect both the stock and an aftermarket sender.

 

hey lively, this is kind of a weird question, but when you refill your oil, can you tell me how much oil it takes to make it go up by an 8th of an inch on the dipstick...its a long story of why i need to know.

 

Ha, sounds like you are talking about priming your oil feed line. I have no idea, because I don't even have a turbo kit yet. Vince supposedly shipped it already, but I haven't heard from him.

Any ways, I would assume it would be 1/4 quart, but that is just a guess.
