I have just got back from a rather damp A1GP and its great to see you here Taiju, welcome and I hope you will enjoy this wonderful place as much as I do. Any information you can get from Mr Togawa will be very interesting

I’ve managed  to cobble together an unpublished article about these Colts without coming across the names of any of the folks who designed and built the engines and Brabham based cars

 

Before pushing the upload button I thought I’d see if anybody has a contact or is aware of any of the technical/management people responsible for this program ? Mitsubishi PR are not interested. My contact is mark@bisset.com.au  . Any tidbit will do, it’s an interesting program about which little seems to have been written in English at least!

One for the Brabham gurus...

 

The 1970 Mitsubishi Colt F2D and 1971 F2000 single seaters were Brabham BT30s, and Mitsubishi built (or local stubbie) BT30 replicas. Can any of you MRD nutters confirm, or otherwise, that this 1971 Mitsubishi PR shot of an F2000 chassis, is, or is identical to a BT30 please?

A Saturn engine is the [in Oz] Galant engine that came in 1100 1200 1300 1400 1500 1600 and in commercials far later 2 litre.

The 1400s and 1600s were used in  front drive Mitsi Colts in the 80s.

No injected 2 litre twin cams in that lot.

Earlier ones had a chain and later belt drive.

It's possible the artist left some tubes out "in the interest of clarity" as sometimes happens in spaceframe illos, but what is shown as the top bracing in the forward bay with the point of the "V" in the center of the cross tube is not consistent with photos of a Brabham BT30. Those had a doubled "V" arrangement between the front and the instrument panel position, with another cross tube between the front and the panel and the points of the "V"s centered on that tube.

Re: the drawing - I hope some tubes were left out because there is so much wrong with the frame as drawn. I doubt if Ron Tauranac could have even had a nightmare about something like the illustration.

Thanks 10kDA, clearly the drawing falls short on detail, presumably it purports to show the chassis of the car below, Brabham BT30-2 raced by Tetsu Ikuzawa in the 1970 Japan GP 

 

 

 

The car was entered as a Mitsubishi Colt F2D, and powered by a 1.6-litre Mits R39B DOHC, four-valve F2 engine, all of this documented on this forum. I wonder how many copies were made as the 1970 F2D and 1971 F2000s were BT30 based?
