Would appreciate some answers, there are a number of community members ready to pull the trigger but need some answers to our questions. Thanks again guys for your hard work.

The street oil cooler is what we would like to recommend for 99% of the owner's of the 370Z's. The race oil cooler will be a bit overkill for the majority of people and just won't be necessary. The street oil cooler has been proven to work very well and offer a big reduction in temperatures. Even on the track the street cooler is working very well. We just wanted to see the temperatures get a little bit lower while on the race track.

Kyle, my apologies if I sounded pushy, I did not realize you were indeed taking care of the 370Z community. Appreciate the response on street recommendations versus track. Keep up the great work guys.

No apologies necessary. I understand your enthusiasm and I thank you for it! If you guys have any questions please do not hesitate to ask!

I will admit that I don't get to spend as much time on the forums talking about our parts as I'd like. I'm kind of nosey so I'm always out in the shop or in R&D snooping around and trying to gather more information. I try to come back as often as I can though to offer more information.

Very cool, e-mail sent

For those of us trying to decide between this and the Nissan Motorsports kit - did you guys upsize the lines to 5/8" for the race kit? Do the Stillen engineers think that matters?

I'm not trying to start a battle here, but I am trying to decide which route to take. It does seem like a 34-row cooler isn't getting fully utilized; it seems surprising that Nissan would screw that up. I guess I'm just trying to find something that will help tip the balance one way or the other...

We have decided to stick with the -8 braided lines. The main factor for this is the engine itself. The oil ports in the VQ37 where the oil comes out into the filter assembly (where the sandwich plate is located) are pretty small. There's no real point to going with a large line after coming out of a small opening. The -8 lines we use are about the same size as the oil channels and this ensures that the oil pressures do not fluctuate too far (if at all) from factory specs. The only benefit to a -10 line is the slightly increased volume. Other than that there will be no gain in pressure or performance.

Kyle, my track cooler was just shipped today.

Question, would I have any issues with swapping in a Mocal 20mm thermostatic sandwich plate?

Just make sure you order AN8 fittings for the plate inlet and outlet..

Do you know if the AN fittings supplied in the Stillen kit fit the Mocal?

Fair enough. Thanks. Honestly, I'm actually leaning toward your cooler because 26 vs. 34 rows means less oil - and less weight - in the front of the car. If the top 8 rows aren't getting direct airflow, they aren't doing much anyway, so it seems like it's mostly just a volume addition.

I do have to hope that the extra few rows on your new cooler vs. the old cooler will be enough to take the heat from a supercharged engine on the track, should I want to go that route in the long run...

^I hope the same too. I already ordered The race cooler and the upgraded steering cooler. The good thing about the Stillen cooler is that the oil cooler is going to be on the passenger side. that and the bigger core made the decision for me.

Any word on the thermo plate you guys said you were going to offer with the race cooler? I need to pull the trigger soon.

There currently is NO properly sized thermostatic oil cooler on the market. Your only option is to separately purchase a thermostatic sandwich plate and substitute it for the supplied unit.

I am in the process of doing this now. Call BatInc. if you have any questions or want to purchase one.

The GMP unit uses a Thermo plate. If you want to retrofit, buy the Mocal and the AN8 to 1/2 adapers to fit the Stillen fittings.

My DIY source has the AN8 to 1/2" adapters...

AN to Pipe Adapters - Aeroquip Straight Male Connector, Aluminum

$3.61 eash..

Remember, the Stillen fittings are 90 degrees. You will also need a 90 degree Male AN8 to Female AN8 fitting. Otherwise the hoses may not fit.
