911 Small Block Chevy Conversion

Renegade Hybrids began producing the Chevrolet V8 engine conversion for the 911/912/930 series (herein referred to as "911") in 1982. Over the past several years, we have refined it into a very complete, highly reliable and powerful engine conversion. Because of the high cost of extracting power from 911 motors, not to mention high maintenance, we feel the Small Block Chevy V8 is an outstanding performance upgrade at a reasonable price.

With Renegade Hybrids conversion kits, a competent do-it-yourself mechanic can transform a mild 911 into a 930 killer. You can buy the kit and all the necessary components for less than the cost of a 911 engine rebuild. Once installed, your Renegade V8 will provide years of trouble free, hi-performance driving, with affordability, low maintenance, greater reliability, not to mention extreme horsepower (if you desire).( pictures )

The conversion kit listed below was designed to work with the 60’s through 90’s Small Block Chevy (SBC) engines. For our all aluminum LS V8 conversion kits using the latest GM LS series engines, please refer to our 911 LS kit.

Options List For 911 Conversions

CLUTCH UPGRADES
After many years of testing and stacks of dead clutches that did not work, we now have a great clutch package that holds power and is smooth on engagement. By modifying the 911 pressure plates, we have been able to achieve and approximate 30% increase in clamping pressure. By changing material to a space age Kevlar on the disc facing, we have seen an additional 25% increase in holding power. This combination is highly recommended foe high torque, high horsepower motors, in excess of 250 hp. (Many racing clutch packages available! Please inquire.)

$375 HIGH PERFORMANCE 915 KEVLAR SPORT DISC
$475 HIGH PERFORMANCE 930 KEVLAR SPORT DISC We use a superior Kevlar compound for a "streetable" combination that holds up to 500 HP. This insures a smooth engagement and better holding power than anything else on the market. (Proper break-in required. Call for more info.)
$335 HIGH PERFORMANCE 915 PRESSURE PLATE
$445 HIGH PERFORMANCE 930 PRESSURE PLATE (Short bell housing early)
$485 HIGH PERFORMANCE 930 PRESSURE PLATE (Long bell housing late)
$595 RACING GRADE LIGHT WEIGHT 915 or 930 (SHORT) ALUMINUM PRESSURE PLATE While you can use your stock pressure plate, you will have much better holding power if you use our Renegade PP. Clamping pressure is about 2200# (2600# = 930s).
$160 911 THROW OUT BEARING
$190 930 THROW OUT BEARING
$135 915 HARDENED CUSTOM RING GEAR
$160 930 HARDENED CUSTOM RING GEAR
$345 HIGH PERFORMANCE CLUTCH PACKAGE FOR 1969 & EARLIER 911/912: 9 1/8" diameter clutch package for early 911/912 has been used up to 400 ft. lbs. of torque. Price applies if purchased at time of basic engine kit purchase.

PRICE IF PURCHASED SEPERATELY:
$275 FLYWHEEL (add $45 for balancing for late model Chevy motors)
$195 High PERFORMANCE KEVLAR SPORT CLUTCH DISK

COOLING SYSTEM
Renegade offers an excellent custom made cooling system. It comes complete and ready to install. If you are on a tight budget, and opt to create your own cooling system, you can purchase used parts (radiator and fans) from sources such auto dismantlers. If you choose this route, you can save money, but much more time will be required of you, as you will need to fabricate and modify parts. Also, Renegade can guarantee neither the effectiveness nor reliability of home built systems. Thus, we highly recommend Renegade's custom radiator system.

$1,100 CUSTOM ALUMINUM RADIATOR ASSEMBLY: Custom built, all aluminum radiator with high efficiency dual fans, automatic fan switch, steel lower mount for radiator, pre-bent aluminum enclosure panels to keep the air ducted properly, and all hardware necessary. Properly installed, this system will keep your engine running cool (180-220 deg.) guaranteed!
$120 RADIATOR HOSE: High quality Gates hose. We run 1" upper hose and 1 �" lower hose from the motor to the radiator. The hoses are located next to the rocker panels, where the factory run A/C and oil cooler lines are routed.
$18 COOLANT OVERFLOW BOTTLE: A 2-qt. Plastic bottle with wire formed support bracket.
$20 HI-FLOW THERMOSTAT: Helps your car run cooler by allowing more water to flow. Does not fluctuate like other brands. Highly recommended.
NEW GAS TANK
With the addition of the cooling system in the front trunk area, an escape for the hot air is needed in the floor of the trunk. To accommodate this addition, the gas tank must be shortened or replaced. If shortened, the capacity is still about 15 gallons. While simple and straightforward, this process does require some fabrication and welding and should only be performed by qualified personnel.

$890 = approx. 16 gal. CUSTOM, ALL ALUMINUM, 911 REPLACEMENT TANK: (for use with our radiator assembly) All tanks include stock position filler neck, breather system, dual fuel lines for fuel injection return, and machined top plate for stock filler neck!
AIR CONDITIONING AND HEATING
Renegade offers air conditioning and heating systems for 911 V8 cars. Our A/C system ties into the original factory installed system. If your car was not equipped with an A/C system by the factory, we also sell components to add air conditioning to you non-A/C car.

$400 A/C MOUNT PLATES: Replaces non A/C motor mount, alternator bracket, and water pump bracket. Package includes A/C mount plates made from Billet aluminum, serpentine belts and drive units. Allows mounting of a high quality compressor. (price if purchased as part of engine kit)
$680 A/C MOUNT PLATES: (PRICE IF PURCHASED SEPARATELY)
$195 A/C CONDENSER (HIGH FLOW): Mounts in front of the radiator, in typical fashion.
$345 A/C COMPRESSOR: New high quality compressor. Mounts to Renegade's custom brackets. Very compact, lightweight, and efficient.
$95 RECIEVER DRYER
$399 AFTER MARKET UNDER DASH A/C (AND HEATER CORE) EVAPORATOR UNIT: Comes with two vent kits.
STARTERS
Your stock starter can be used, if you have a 1972 or later car with the 1.5 hp starter. While Renegade offers a replacement 911 starter, we recommend the other option, our lightweight, high-torque starter.

$399 PORSCHE 911 1.5 HP STARTER: Rebuilt by Bosch
$239 HI-TORQUE, LIGHTWEIGHT STARTER (STAGE II): Modified and fully rebuilt Japanese starter. Has approximately 40% more power than the 911, with about half the weight; approx. 8.5 lbs. The best choice for V8 application.
$289 ULTRA HI-TORQUE, LIGHTWEIGHT STARTER (STAGE III): Designed for ultra high performance engines exceeding 10.5 to 1 compression. If you have any doubt, this starter will do the job. With 80% more torque than the best Porsche starters, motors up to 13 to 1 compression will be no problem.
ENGINE WIRING
It only takes 6-8 wires to run a Chevy V8, but unless you find pleasure in routing and untangling wires, Renegade offers a solution to make this process quite painless. (74 and later cars only.)

$195 WIRING HARNESS: Renegade does all the messy work for you. No wires to untangle, bundle together, or decipher. Our wiring harness comes completely assembled with each wire labeled. Just install it on your engine and raise your engine into the car, then simply plug the other end of the harness into the factory 911 plug.

SENDING UNITS: While stock temperature and oil pressure gauges can be utilized, the sending units must be changed in order to work the V8 set up.
$25 COOLANT TEMPERATURE SENDING UNIT
$45 OIL PRESSURE SENDING UNIT
TORSION BARS
Because the weight of the V8 is similar to that of the 930 motor, we recommend upgrading the suspension similar to that of a 930 car. To maintain proper handling, the rear torsion bars must be upgraded. Upgrading of the front torsion bars is optional.

$330 REAR TORSION BARS: Available in sizes from 26-30 mm.
$325 FRONT TORSION BARS: Available in sizes from 21-23 mm. While this upgrade is not mandatory, larger front torsion bars will provide improved handling.
GUARANTEE
The motor mount, adapter plate, alternator bracket, water pump housing and water pump bracket are guaranteed against breakage under normal use, to the original purchaser, for as long as he/she owns the car. All other parts are considered wearable and are not covered by this guarantee.
