Mocal Cooler Install

No smoke, no mirrors, just fast.

Instant-G Oil System

We sell the basic kit for $875, but we recommend the 44 row upgrade.

Includes the following:

Three 90 degree -12 hose ends
Five straight hose ends
22-28' braided hose
Mocal -12 thermostat
Front radiator style oil cooler
Front mounting brackets
10 mounting clamps
Two 30mm to -12 FEMALE to MALE adapters.

You can use this system when converting to SSIs or headers and eliminate the factory "J"
pipe that usually goes from the engine oil outlet pipe to the thermostat, and the pipe from the
thermostat to the oil tank.

If you chose to keep these, you'll need 30mm MALE to -12 MALE adapters. This setup
is shown here. That system also includes a LARGE nose mount cooler and is $1045. Upgrade to a B&B cooler for $200 extra.

If you need a system for a 1972 car, see here. Pricing is others plus $25

Sizing: For up to 3.0 in all climates I'd recommend a minimum of the 44 Row.
For 3.2 I'd reccmend the 52 Row, which is similar to the factory cooler.
For 3.6 I'd recommend dual fender mounts (such as a Carrera in the Passenger and a 52 Row in the Driver's fender) or a single 72 row cooler in the nose.

For 3.6 track use I'd recommend a minimum of the 72 row,
The largest coolers you can run in early RS bumper is a 50 row, a PC 10 or a B&B. The 72 row will not fit.
*** To use a nose mount cooler you must have a RS (early) or 930S/Ruf/SCRS etc. front valance/bumper.

You cannot mount a nose mount cooler behind the stock "S", SC, or Carrera bumpers.

All oil coolers are special order, so please allow 1-2 weeks extra for coolers to get in stock.

Thermostat on SC.

Note position of thermostat. You need to loosen or remove the rockers. We chose
to remove them.

Tuck the hoses under the rockers using the factory brackets. The Mocal thermostat bracket is worthless. Toss it.

This is the inexpensive 19 row Mocal cooler. A very tight fit. Needed to weld a stud
on for the lower mount. Have Mig, Will travel. Upper mount goes through headlight bucket.

Figure on a solid 3-4 hours for the install. You'll need a cutoff wheel to cut the braided hose.
Some people claim you can use a hacksaw. Dreeeeeaaaammm on! If you buy the kit from us, however, everything is preassembled. You can also upgrade to the larger horizontal slat cooler for $100 extra.
