A bit research yeilded these figures for the V10;
2002 RA002E
94 degree V10
Chosen angle reduced pressure wave interference.
97 x 40.52
600mm length
108mm bore spacing
68.5mm crank height
111kg weight
177mm cog
Open and closed deck versions tried.
Scavenge pumps and de aerator one piece to cylinder block.

Thanks! Oddly enough Honda also just wrote a piece about the RA002E https://global.honda/en/POWEREDbyHONDA/2002_ra002e/

On the rebuild, still chipping away in the background. Nothing too much to report currently but some parts purchases should lead to some good progress relatively soon.

Wow, the follow on link for the BAR004 reveals that Reynard were bankrupted near the end of this cars development, making your car one of the last reyanrds ever produced.
Thats a pretty cool talking point.

Actually I hadnt thought of that, that is an interesting little extra bit of history to the car. That 004 summary is interesting, factual and to the point. I guess Honda didn't mind pointing out the issues with the chassis/BAR.

Finally a worthwhile update after being away with work and mainly searching for parts.

I had to go for it and gambled on quite a pricey pair of Arrows A21 rear uprights and driveshafts. There are so many variables within this area it was a bit of a risk but getting stuck in today it looks like they will work :)
Image

Wins
The tripod driveshafts fit my gearbox ☑
Image

Tierod attachment seems perfectly located ☑
Image

Brake calipers fit the rear rims with no modification ☑
Image
Image

Issues
Only one wheel nut (If anyone has a blue L/H tread A20 or A21 wheel nut then please let me know!)

Hub locating lugs do require modification. The Arrows features 6 (3 bullet shaped and 3 smaller cylinder shaped) lugs. My Minardi rear brake bells only have holes for 3 lugs. This meant I had to modify the Arrows hub by removing the 3 cylinder lugs. The first photo is post removal. I had hoped they would unscrew but I had to grind them off. The spacing of the remaining lugs is also slightly less then the Minardi rims and bells. My solution is to enlarge the bell holes and 3 holes in the rim.
Image
I still need to do the brake bells but the titanium will require better drill bits or some outside assistance.

Made some mock up rear arms out of MDF to check how it all goes together with the Arrows uprights and then for use as templates for some steel final versions. A few bits to finish but happy with how its looking so far.

The bodywork sits nicely over the mock arms confirming they are very close to the original arms location

Also received my mirrors, SuperAguri red wing and later BAR wing that was a more cream shade of white back from paint. I went to a local accident repair centre in the end and am really pleased with the results and service. Shout out to Bodytec UK in Reading. I am sure I will have some other bits for them in future!

Pre decals
Image

Wing built up and decals applied. Not the easiest job when your vinyl cutter is only A4! Still quite happy with the results.

Mirrors stickered up and installed. Peeled the mirror glass protection off the right mirror, couldnt resist!

Nice detail to be done with when still half the car is missing :lol:

If the gearbox was still functional, i woukd almost try to make that rear susoension functional too., The arrows stuff looks a good match.

Yes I am planning on making use of the shocks instead of just fitting a solid bar holding it up. Dont think I will be able to have ARB or proper heave shock and spring in the middle but I will definitely try to have it pretty functional. We'll see what happens when I lower it down for the first time!
