in all seriousness, im sure a drop in dual core aluminum radiator will be sufficient, and it looks like room wont be an issue. then just make sure you go ahead and shroud it well.

 

Cool setup.

How is oil cooling handled in this particular case? What do S2Ks do stock for oil cooling?

 

Oil cooling is achieved the same way it is in 1.8 miatas, with a water cooled assembly at the oil filter.

 

Since you have mastered rad mounting, I'll recommend the PRC twin core, dual pass, cross flow I have. The detailed images link on that page shows diagrams of the models. This is the rad used by circle track guys, but I found it per the turbo Z car guys which several used to cure cooling issues in their boosted track cars.

I'm using 2111003 19" x 22" Ford which is narrow enough to allow side-by-side fitting for a full size Mercedes oil cooler (with some minor mods) in the front/mouth of the Miata.

 

your not gonna want to use a miata upgrade rad because of the inlet and exit holes in the rad! on the F20c motor your upper rad hose is on the driver side of the car and it runs into the driver side of the rad.....for miatas our upper rad hose flows out the front into the pass side of the rad....

when you go to purchase your upgrade rad find out the dimensions of a aftermarket rad that is made for the miata and keep those dimensions in your head while looking for another rad with the opposite inlets and exits

I think I may just get a radiator built from scratch. I have a friend who built a rock crawler and had a custom unit done for about $350. M2supercar, your set up looks well thought out, what model benz did the oil cooler come from?

 

I think it came from the 123 series... it was a 70s or 80s diesel. I just shopped by dimensions until I found something OE on ebay that would fit. This one holds ~quart plus the lines. Another option with greater capacity is the FC rx7 cooler. Work well with a full width but shorter rad for stacking. There's usually a bunch of circle track oil coolers on eBay too- which are usually short and wide - optimum for oil cooling and designed for stacking. More oil is your friend, and your cooling system's friend.

 

+1 for the separate oil cooler if you have a slight issue as well. I used a relatively small Setrab oil cooler in PHX on a 2L turbo with great results. It takes some of the load off the primary cooling system.

 

Thank you for the input guys! I have been on a couple of the s2000 sites, and to tell the truth, most of the time i feel like I am trying to have a conversation with the cast of the fast and furious. The sites seem to be very ricer oriented, not the case here at all.

 

That would be sick to drive, 9k redline in a miata

 

Not all of us live our lives a quarter mile at a time

 

How true!

There was a request that I post a thread on the build site. I want to let you know that I will be doing so, but it won't be for a couple of weeks. I have my boards on the 22nd of this month, and need to study for them. However, as soon as I have taken them I will post on my build.

 

what boards are you taking? Where are you located?

 

I am in Colorado, taking my licensing test as an RN this month, so I have been spending most of my free time studying.

 

Nice build I cant wait to see a turbo going on it! good luck with the Radiator I have the CX racing one and it works well for me but as stated earlier the out let is on the passenger side.

 

Just started a thread on my conversion over in build section for those interested.
