My conversion took approximately 5 months of work to get the engine in and get the car on the road. Another 18 months for further work and improvements. Thanks very much to the 914 Club Forum and those who posted their conversion information and to those who responded to my questions, and special thanks to the club members who attended the V8 conversion meeting in Pleasanton in September 05 and shared their valuable knowledge with me.


If anyone is interested in seeing the car, I live in the Richmond District of San Francisco.

Treated miscl rust with OSPHO and Por 15 paint
Herculiner truck bed liner in front and engine compartments

New / custom throttle cable
HP mini-starter
2-gauge wire to starter
Ron Davis Radiator with two 13”diameter SPAL fans (Renegade set-up)
Renegade bypass thermostat system
VDO Water temperature gauge
VDO Oil pressure gauge
VDO Oil temperature gauge (original)
Tachometer upgrade by bigmarkdesign
Oil Cooler
Center console
Rear trunk strut conversion kit – Camp 914
Magnaflow dual-in dual-out muffler
Body work and re-paint
Power mirrors from Honda del Sol
Rear wing from Toyota MR-2
Interior seat and backpad kits by Autos International
Carpets by Morph
Towbar for flat towing with integral wiring harness
16" 4-lug Superlight wheels from Pack Racing Products
BF Goodrich G-Force Sport 205/55/16.

The dyno tests were done this 8/24/2008 at the Thunderhill dyno. At max rpm of about 6,250 the dynamometer showed a speed of 153 mph. On the track we got it up to about 125 mph. However, it threw a water pump belt a couple of times. I think that there is too much flex in the Renegade water pump mount, so I need to reinforce it.

At rear wheels: 263 ft-lb torque, 241 hp.
Engine: Assuming a 15% loss through the transmission, the engine would have about: 302 ft-lb torque, 277 hp.
Maybe more if the test was done on a motor dyno stand without water pump, alternator, and muffler.

I bought the car in June 05, ordered and collected enough parts to start, and removed the engine at the end of August.

Nick,

Great job, another Bay Area conversion! (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

FYI, We have another "member" who bought Renegades flagship "Peal". A conversion meet this summer will be huge!

At this time, I have not committed to cutting the vents in the wheel wells. I am going to experiment with various hood ventings - perforated plates, louvers etc. I have three hoods to work with. If none of that works properly, I will then cut the vents in the wheel wells:

Engine compartment was also cleaned out of rust, painted with POR 15 paint, primered, and final-coated with Herculiner truck bed liner. This is the compartment after engine removal and initial placement of the coolant components:

Trunk was de-rusted and treated with POR 15 paint. You can see the Herculiner in the engine compartment, the distributor cutout, the relocated battery, and the strut-type trunk lid springs:

Transaxle was thoroughly cleaned. All of it was as black as the inside of the bell housing in this picture. All seals were replaced:
