I took off my HP kit and now building a rear/mid mount turbo setup. The turbo will be behind the drivers seat, run up to the existing HP cold side then into the motor. If I like how the car runs, I may do a W/A intercooler behind the passengers seat, and take the A/A off.

I have been looking around at oil return pumps. What do you guys think about this one?

It kinda looks small,1.3 GPM, but unless at WOT I don't see a lot of oil needing to be returned to the motor. I plan on using 3/16" brake line for the supply, 1/2" copper back up to the motor. Through the reading I have done here it would seem that a vented catch tank under the turbo would be a good idea. Would a large catch tank enable this smallish pump to work for me? I am thinking that as long as the tank did not over flow by the end of a WOT 1/4 mile I would be fine. Any thoughts/suggestions besides put the HP kit back on? Price is an issue. Thanks.

When I was looking at rear mount setups a guy recommended this pump. He had been running it for a while with no problems. I don't trust non name brand stuff. If they don't think enough of it to put their name on it I don't want it. For an extra $30 I would go with the Tilton pump

I would like to get the Turbowerx pump, but I really don't want to get to much cash into this rear mount deal. If I stick with the rear mount I will be adding V-bands at each connection at a later date. Right now I have more time than money.

I have looked at the Tilton pump, I am not crazy about it being plastic. Also in my searching I have found some cases of there failure after a few hundred miles. Not that a Goggle search can provide only unbiased facts. Perhaps I will have to be the one to try one.

I did a ton of research on return pumps and ended up with the overpriced turbowerx pump. What seems to always be recomended is a gear pump. If you do go with the diaphram pump try to mount it as far away from the turbo as you can to allow the oil to cool. They don't like 300 plus degree oil. I did a mid mount on a 2005 g35 and have no regrets so far.

 

I would say it would be ok to use , it looks like a knock off of the Shurflo i use which is a great pump and the Shurflo only cost about $30.00 more.

LIQUID TEMPERATURE 170 degreers farenheit max

 

Yup. Most diaphragm pumps I have seen for sale have a low temp rating. But people seem to getting by fine with them. Maybe mounting it up front would help...

Go to the junkyard and pick up a small oil or trans cooler. I used one off a ranger to replace the factory p/s loop when I put my front mount intercooler in. You can mount them horizontally and still get some cooling, for a few bucks its a good piece of mind imo

 

1/2" copper sucks balls to work with. Not really that flexible. I went with the e-bay pump.
I plan on doing a thread on the rear mount in the builds forum.

I'm a big fan of these guys:

Realyl nice stuff. Plus, they say to run the pump without any sump, which is a nice feature.

 

Yup, I came across that site in my searches. If I decide to stick with the rear mount thing long term I may upgrade the pump in the future. I ditched the copper idea and the catch can for now. I did however keep the vent. I ran 1/2" npt from the drain down through the floor to some 8-an Parker pushlock stuff I had left over. After the pump I am going to try 3/8" rubber line up to the motor. It is cheep and I think the smaller diameter might reduce foaming of the oil. I could not fit a oil cooler after the turbo without a bunch of cobbin, so I put it before the turbo in front of the radiator. Cooler oil into the turbo cooler oil out? I don't know, I guess I will find out soon.

I used this pump on my buddies mid-mount turbo setup. Its gravity fed down to the pump about at foot with 1/2 hose. The pressure side back to the motor is patched into the original steel 3/8 fuel line to the front and then up to the valve cover.

Ran it all last summer without any problems. No drain back problems cuz the turbo is up high enough.

 

I have the car up and running. The oil pump seems to be working very well. Actually it pulls some vacuum. I have a vent at the turbo and you can feel the suction from the pump i you cover the hole in the vent with you finger. I t is in this picture, the vent is on the end of the 1/8" pipe.

Do you really need a vent I have heard people using them.

 

I could not tell you if you do or don't, I have seen pics of it done both ways. But, it seems to me that I would not want the possibility of oil being pulled from the turbo. Also, I think that the return pump will live longer if it is not working as hard.

I ran the pump while priming the motor with a drill and the pump was pushing the oil up just fine.

I did a build thread here if any are interested;

Now I need to take care of a hood scoop of some sort. The carb hat is now 2 1/4" above a stock hood. I might just leave polished hat sticking through the hood.
