I was wondering, if this will work for a 96-00 civic? If you go to http://www.Greddy.com and look under the TECH section. Click on the CIVIC EP3 TURBO KIT Part 1. Under Section 3-7, you will see that a picture where Greddy made the oil return line that uses a banjo bolt, and bolts in place of the original drain plug. Will this work for my civic, instead of welding a return flange, I want this setup so I can install and uninstall turbo on my car. Is there anything wrong with this set up?

 

I don't see how it could work without messing up the turbo. The drain bolt is at the lowest point on the oil pan so the oil will drain. You want the oil return line to be as high as possible so the oil won't back up into the turbo. Get what I'm saying?

 

i agree its too low if you do this you will shoot oil out from your turbo and everything you need it high not low

 

Thats what i was thinking, I was wondering how can greddy make a return line that low and make it work. Oh well, I guess I will get my return flange welded on the oil pan, and plug it up if i ever need to remove the turbo. I am thinking this mostly for smog since i am in California.

 

The question should really be, "Why does having the oil drain too low cause problems?" If you think about it as a siphon, there should be no difference at all having the drain above the oil line or below it. Gravity will keep the level of oil inside the drain line equal to the oil level in the pan.

There can be only one explanation that I can think of: Viscosity. Oil is thick enough that it doesn't drain quite fast enough when it has to siphon. But Greddy probalbly just constrict the feed line significantly. This should be fine. I have been running my turbo for 2 years with the feed consting of a -3AN brake line (about 1/2 of the cross section of normal -3AN) with a 1mm restrictor, and the oil dribbles in. Once I forgot to hook the line up and started the car. I lost about a pint of oil in 30 seconds.

thats why this works. well said. there is no problem with this. there are a few other kits that do the sanme thing.

 

Cool, I probably will do this set up for my car then, then I dont have to get it welded. Thanks

 

IF the crankcase is properly ventilated, you wont have any problems. There are a few factory turbocharged cars that have oil drains that are damn low.
The big word is "IF" though, since a lot of people you see having problems dont have a properly vented setup.

 

If you dont have the time and the patience to do it right...When will you have the time to do it again..Unbolt the oil pan and spend 10 bucks to have a -10 fitting welded in. It took me an hour to complete the whole thing. Why chance messing up your turbo..
