Cool what you are doing. Was intendent to go and watch one of the last two races, Kemora is only about 10-11 hours away. But i was not able to.
Ahvenisto looks like a fun track, https://www.youtube.com/watch?v=lKVHlGrxxCU To bad the Escort did not have a rear view camera.
Do you have any videos? At Kemora you just pulled away, https://www.youtube.com/watch?v=8PNMU80xED4
How much do you miss a fifth gear at Kemora? (or other tracks for that matter)
Guess the 4,875 is the R-180 from the diesel 720 (the gasoline had 4,625). I tried the 4,625 once but never got to the 4,875 and 5,143 i have.
You mentioned a L-20B, from where? How many times have you lost cars at auction?
From videos rokkirally reminds of something between jokkis and rallycross, sounds like bigger engines too.

Ahvenisto is really fun and also very challenging track to drive, built in 1967 and still has original profile, only some safety changes over the years.
There i use 4.375 rear diff, but Kemora i use 3.90 ratio so don't need fifth gear.
Maybe i should buy incar camera for next season?
Yes 4.875 R180 is from 720 4x4 diesel, we didn't have gasoline version 720 4x4 here.
That "L20B" is actually Z20 bottom from D21 pickup with L18 head, L20B is impossible to find here.
I've lost my jokkis cars at auction about 15 times, few times i got them back from next race auction.
There are two gategories of rokkiralli, super-class is close to rallicross and other class is close to jokkis.

Yeah, buy a camera. And don't mount it as high as in the Escort. It was a little too high there.
i guessed it was a Z-20 block, the L-20B is said to never been delivered to Europe. But some info said it was in UK and the Netherland.
So then you missed the opportunity to build a L-22B engine.(Z-22 came in 720) What about the Z-24, did you got them? They came here in the D21, Terrano and Vanette. The Urvan got the Z-20 and 2,5l diesel here. The L-22B and L-24B are strong jokkis engines.

The historic 510, what spring rates and stabilizer bars are you operating with? Any change from different tracks?
What are the rules saying about springs and bars? Can you have any kind of adjustment in the suspension?

I have Z24 block from D21 "under construction" to jokkis use, but have to add over 100kg more weight to the car because bigger engine.
Historic 510 has front coilovers 300lbs springs, koni shocks and 610 20mm bar, rear has M-B W124 6-cyl front springs, KYB shocks and Datsun 1200 coupe 19mm front bar, there is some adjustable things but i have same settings for all tracks.
