[QUOTE=Wombat;1007307]I saw some folks on the UK Mazda 6 forums talking about biodiesel, but I don't think any of them actually ran it. There was also some chatter on a Russian camper van forum, too, but reading the translations were giving me a headache.

I do not know of a central source (other than Japan), but there seems to be JDM importers along the east and west coast that get these in every now and again. There are two places on ebay currently selling them:

One in Kearny, NJ (where I got my engine): http://www.ebay.com/itm/MAZDA-BONGO-BRAWNY-2-0L-TURBO-DIESEL-ENGINE-TRANSMISSION-HARNESS-ECU-JDM-RF-/230973133852?pt=Motors_Car_Truck_Parts_Accessories&hash=item35c712541c&vxp=mtr
One in Jamaica, NY: http://www.ebay.com/itm/MAZDA-BONGO-BRAWNY-2-0L-TURBO-DIESEL-ENGINE-TRANSMISSION-HARNESS-ECU-JDM-RF-RF6D-/281104931297?pt=Motors_Car_Truck_Parts_Accessories&hash=item417328d9e1&vxp=mtr
What's funny is I seem to have driven the prices of these engines way down. The outfit in NY was selling them for $1999.99 at one point, but weren't getting any hits. The ones in Kearny had a no reserve at $999.99 and were selling around $1250. I went up with cash and bought it outright for $1100 and I see that the Kearny outfit has a buy it now slightly higher than my price and the outfit in NY dropped their price significantly.

I thought the gauges were going to be tricky since I assumed they would all be over the CAN bus network, but after reviewing some of the wiring diagrams, it looks like all of the gauges have their own individual signal wires. If that's the case (and I haven't spent a lot of time looking at the instrument cluster diagrams), it may be a lot cheaper/easier, although I was kind of looking forward to having an excuse to buy one of those fancy customizable gauge clusters.

I also need to change the title of this thread. After further research, my engine is an RF-CDT (RWD version). The MZR-CD is the FWD version used in the Euro/Japan-spec Mazda 3, 5, 6 and MPV.[/QUOT

DIME A DOZEN?:nope: well done sorting the wiring though and i guess for a modern engine and trans thats not a bad price compared to 300k mile mercs
lots of good and bad choices out there when you dig around i had a 3ltr mazda perkins once. but one good rwd set up and dead easy to wire is a 2.7td nissan fitted to fords nissan even some london black cabs

as some of these are still hard or expensive to locate and the merc into truck has been done so many times? whats the best manual trans to attach to the merc>? any obvious choices i never knew it was such a common swap. im all for being different but i dont need the extra work these days

I am running a 2002 Kia Sportage 4WD with the RF Turbo version MZR-CD (70,000 km) and I have a second similar engine I want to put in a pickup.
Have you done any more with this engine since your last post?
Beautiful engine BTW.

Great Start. But that spaghetti Bunch of wires looks awfully daunting to say the least.
