r1/r2 2nd oil cooler vs single larger
 

I'm have/planning mainly boltons and a street port for my rx7 running 5-15 lapping day events yearly, plus other driving.

What will work better, Will the r1/r2 2nd oil cooler fit my needs, or should I look to getting a 36 row earls single cooler?

Also, are there any fitment issues putting the r1 passenger one on with a pettit cai?

Thanks
Jeff

The R1/R2 setup is ideal. You won't have any mounting problems with Pettit intake. Now all you have to do is find a spare r1 oil cooler.

Check the Crooked Willow site the have a nice dual cooler upgrade. Max Cooper also has a good write up about them on his site

www.maxcooper.com in case you don't have it already.

What about?

I need better pics. Will the cooler mount in the side opening or the center?

Later, Jeff

The larger one will mount in driver side opening, that's why the recommend a front bumper with larger openings to benefit from the larger cooler. The pic makes it look like it goes in the center. It doesn't.

go to they have everything u need at a good price

im4u, you can't post the name of that store on this forum. Just letting you know why it doesn't show up in your post.

rx7store has them too

why cant i post that store u all post rx7store whats wrong with

It doesn't make much sense to get a 36 row if you still have the stock front end. I doubt it would be much more of an improvement over the 19 row. I would suggest the Crooked Willow Kit or the dual 25 row that rotary extreme makes.

Does any one else sell the Crooked Willow kit or is it something you can only get from them? Just trying to get the best price. Of course it is about what I was expecting to pay for it.

There is currently a group buy going on, kit is about $820 shipped, about $100 off the list price. Contact duane at CWC.

I e-mialed him but have not received a response yet. It looks like I might be a little late but maybe he will let me in on it.

Just get the gb kit or go to a junk yard and find the kit off another car..

On a track day my r2 was showing a lower temp than my friends with a upgraded single, but only by a few degrees..... different cars though

I can't find any oil coolers at the rx7 store...what about using a B&M racing trans cooler as an oil cooler (with thermostat)?

Don't use the B&M.

Goto Pegasus Racing and get Oil Cooler 5.75" high, 12AN Fittings, 19 row 1210-19-12A Price: 135.88 .

Use 18mmx1.5 to 12AN ringed fittings, your choice of hose, and the MOCAL Oil thermostat. While you're doing this, why not block off your current oil filter and run a remote filter? And if you're going to do that, add pressure and temperature fittings. You can do all that for less than anyone elses single oil cooler upgrade.

The BEST part of the Crooked Willow kit is the FANTASTIC Carbon fiber ducts that are included - they seal tight to the coolers (much better than the stock ducts to the stock coolers) and are easily worth $150- ea.
MARIAH told me the could not duplicate the kit (w/ ducts) at any where near the CWR price.
