Bio diesel swap

Postby codysimar » Tue Aug 27, 2013 12:40 am

So im considering dropping a diesel into my crx and making it into a bio diesel
My best friend is a diesel mechanic for the marines and has a garage on base to do the swap
Im not only cnsidering it for mpg and long term cost but emissions as well
If you think its a good idea what engine do you think is best if there even are multiple options
right now the only engine ive heard can fit is a vw rabbit
so yeah what are your thoughts on this?
all feedback is welcome

Not many do this because it is a complete fab job.
Seen it attempted on a 1st gen Crx with a MK2 Golf motor.

Maybe try asking on site more dedicated to this type of thing, such as diesel motor site or a fuel economy site like
ecomodder.com.

Never seen one in a crx, neat idea though.

Because with this he could expect anything from 60-100mpgs.

The emissions from vegetable oil are 90% less plus a full tank of gas would be nearly free. I have an HF but with a ZC :( no 60+ for me

At the very most I would swap in an HF motor/trans, run regular cheap gas, our gas tanks are cheap as it gets to fill for regular cars. Swapping to biodiesel is a huge ordeal, you may get good biodiesel mileage but the car would probably be alot of work to maintain and very confusing to trouble shoot when things go wrong.

I cant see either of those options being near as fun as the ZC motor you already have installed though.

You could always spend a few hundred on a chipped PM6 ecu and run TurboEdit, tune it lean on the highway. I ran 40-45mpg on my ZC with a ZC trans. And the car was still a blast to drive which is really the best part of driving a Crx.

I bet if you threw in a different transmission onto your ZC you would be happy with the results, and maintain Honda reliability

Another thing to mull over is the cali thing.

Your in cali and all the government stuff associated with it.

Take it from somebody who has seen the bastard project been sold to the next person.

My buddy shoe horned a 302 into an opel gt. There was so many things that he did with motor, fuel pumps etc.

The next person bought it and it was a huge learning curve for them as well as the constant phone call of how did you do this.

Swap the tranny to a hf tranny or find somebody selling a hf motor.
