Hey guys. I've been reading about how the oil return line for the TN kit might have issues with the spacer. So I decided to tap it into the oil pan itself. But what I'm trying to debate is whether it would be better to use a spacer or a larger oil pan to get the extra quart of oil in. Any info to help me decide would be appreciated. Thanks.

 

I like my spacer.

 

Add an oil cooler. It increases oil capacity and you get a cooling method as a bonus.

Well, people are going to tell you both sides of the story, TN says that tap the upper block thats the recommeneded way. But there are people that have ran spacers without issues. But there are also a couple folks that have had problems with the spacer blowing turbo seals.

So its pretty much a personal choice.

^^ and a cooler is a good idea, more oil and cooler oil temps for the motor. ( I run both the spacer and cooler )

About how much more oil will the cooler alone add? I didnt think of that. I like the idea cause I can still get the GT Spec brace that would otherwise not fit. I'm going to be tracking the car so I definately want to add some oil and make it handle better. Oil cooler sounds like a win win.

 

amsoil bypass twin filter system adds 2 qts to the capacity and keeps the oil cleaner.

 

When u say tap into the Oil Pan ---I hope u mean the upper oil pan

 

one thing alot of people forget is that you are using a variable viscocity motor oil......you don't want to add too much oil capacity or too much cooling capacity as that won't allow the oil to reach the optimum temp/ viscocity to properly lubricate the engine.

 

Yes I do.

 

Just chkin ---- I have no way of knowing ur experience and didnt want to take it for granted

 

Would or could this be used with an oil cooler?

 

If you add a thermostat controlled oil bypass sandwhich plate then the temp will always be right on.

Which member on this board has this setup? I remember seeing pictures of it.

 

Spacers are less expensive...my vote is for the spacer. If upgrade oil pans were less expensive, I would do the pan.

Oil coolers add about 1/2 quart extra capacity.

Let us know if we can help. We have spacers and Oil Coolers in stock.

 

Any particular spacer that fits/works better? JWT? AAM?

 

I run a JWT spacer, a Setrab oil cooler, and the Amsoil bypass filter with the 100 (8 inch tall) filter. Adds a LOT of additional oil. On track this weekend the temps were pretty steady at 95F throughout the run. When we got on it really really hard it would climb to between 95 and 100F (water temps), but never above 100. Within a couple of minutes of pulling in and leaving the motor running it settled right back down to 95F. This is using a twin turbo JWT set up, with .9bar of boost on 100 octane unleaded gasoline. Outside temp about 60F, at Laguna Seca this past weekend. Using a three core Koyo radiator too.


You can see the comparison of the size of the Koyo and stock radiators from the above picture.


Here is the bypass filter, only right now I am using an even bigger filter than the one shown above.

 

Nice pics Eagle1. I assume you are refering to degrees C in your above post. Great coolant temps for a car driven in those conditions, at the level that you push yours.

In regards to JWT vs. AAM oil pan spacer. Both nice pieces. The AAM is a little more expensive, becuase they have pretapped the spacer for oil return lines and an oil temp sensor. JWT is $100, and AAM is $155.

 

I never had an issue with my TN set-up and a JWT spacer with the oil return tapped in. Also been trouble free with this on the Greddy set-up and AAM's pretapped spacer. IMO-most of these issues are due to incorrect oil return routing (Ive seen some idiots not cut these short enough producing a u-bend in the line before going into the spacer), than the actual point of oil return. But this is one of those things that car guys will argue over till the end of time, one/a few guy(s) has a bad experience with his oil seals in his turbo and he bad mouths the whole package. Just the way the cookie crumbles...

 

Being fully CNC machined, I would assume the AAM fits a little better.

My JWT spacer that I used to have fit, but the holes were ever so slightly off and it required me to install the bolts in a specific order or I would be left with a couple that I couldnt get the threads started.

I went with a front mount oil cooler and Greddy oil pan when I get rid of it. I like the Greddy pan because it has provisions for turbo oil returns, and is just barely larger than stock. I dont like the idea of a pan that is wider then stock, I would prefer to just keep stockish size or go with a spacer for better oil control. I get my extra capacity from the cooler and lines.

 

Eagle1, are you not running your inner fender liner at all?
