Oil Cooler for 2366? Options

[r_towle]

Or you could talk to more than a few people, including the winner of the runoff so for more than a few years with a 2.6 and see what they are doing.

I also do agree, put an oil cooler on the motor.
Get headers from foley, he has a heat solution also.

Then drive it like you stole it.

And by "Foley" he means Chris Foley/Tangerine Racing.

Dude, good to see you still lurking around...with a carrera no less....cool

Shane (Jetsetsurfshop) built a similar engine for his car. He tried all kinds of arrangements of ducting for a rear-mounted cooler. Found out he could only keep it cool with a front-mounted cooler. Granted, this is a track car, but even on the street, that's a lot of heat for a rear-mounted setup to deal with. Yes, the plumbing sucks, but in the long run, I still think it's better to just get it up front where it belongs.

That seems to be the concensus. Any suggestions on how to accomplish this? If I do a front cooler, how do I keep the hot air from just getting hung up in the trunk? What about putting the cooler in the floor of the trunk, rather than the front of the car?

As sort of mentioned already, any effort to improve exhaust flow and reduce pumping losses will allow your "improved" engine to run cooler.
Limiting the amount of heat you have to shed will expand your options for how to (mechanically) deal with cooling of that extra heat.

The factory racers put the cooler at the very front of the front trunk. They cut holes for the air coming in, had ducting to make sure the air went through the cooler, then more ducting to run the air out the trunk floor. That's pretty much the "proper" way to do it. You can probably do much the same thing, and have the cooler on the trunk floor instead of at the front of the trunk. I suspect that the cooling effect will be about the same, because the air flow will be about the same, but I could be wrong.

I've only seen a couple of 914s with coolers in front of the body. One had it mounted as a very thick license plate bracket; that seemed to work pretty decently in the Pac NW. Others have put them in cut-out fiberglass versions of the 75-76 Rubber Baby Buggy Bumpers. Not sure how the air was ducted away from those. They were there because of racing rules that prohibited holes in the body for cooling air.

I'd like to keep the stock front valence and bumper, if at all possible. So, a couple ideas have been bouncing around in my head, any of them worth pursuing?

1) Mount oil cooler in front wheel well. Remove the horn and duct air to the cooler through the bumper grill.

2) Remove the front air box and put a scoop over the stock baffles. Mount oil cooler where the air box was and direct air over the cooler and out near the master cylinder

3) Use a rear mounted cooler with a fan and use an air duct cut in the rocker to force fresh air onto the cooler

Thanks Stu, that helps a lot. I really like Trekkor's setup (post #10 in your link). If I go that route, would a GT valence with the stock bumper give me the proper access to the grommet holes he is using for intake air?

Also, silly question time - how should I run the oil lines from the front trunk back to the engine?

I ran mine through the pass side longs.
Some run them under the car, and some go under the rocker panel like the 914-6 GT.
Someone on here even made hardlines for that routing.
I'll bet that you could even use flared copper for those lines as long as they never took any load that could work harden them and cause them to crack.

That would be interesting. So how would I put the fittings on to connect to the soft lines from the cooler and to the engine? What kind of flare would that be?

I didn't either. I saw some custom ones he built, but nothing off the shelf. I'm wondering if there is a way I can make my own hard lines. Anyone have any suggestions?

Middle of page.
It is not intended to be a front mount, but the only real difference is in the length of the hoses.
I used 12AN to run to the front & back again. 35 ft of 12 AN hose is pricey.
My entire front cooler system cost me close to $1000.
