I don't think we can estimate cost differences. We don't know the regulations (also price level set by FIA which is applied for example for S2000), numbers for production, in fact almost nothing...

I compared (post #35) gearboxes with different amount of gears and torque (R2 having 5 gears and coping less torque compared to a 6 gear R3 gearbox). Then I just wondered how much coping with higher torque affect the price compared to more gears (5 gears vs. 6 gears).
In the second part I was referring to my previous post (#35) where I said:
“Another would be if the engine could be kept standard but would the standard engine cope with a power increase from about 150 hp to about 300 hp.”
Instead I should have said:
“Another would be if the engine could be kept standard but would the standard engine cope with the higher torque”.
Torque instead of power because it’s the torque that counts.“Don’t eat the yellow snow” Frank Zappa

simple example....for evo 9-10 a 5speed dog-box ,you can buy as new from 5000 euros to 10000 euros.Depents from the manufacture.
sequential dog boxes for evo 9-10 start from 8000 to 12000 euros.
All of them have the same gears(5 or 6speed) all straight cut,all can cope with torque at wrc level,and plenty of them have been worked perfectly at 500-600-800 bhp time attack cars.Also the ''cheap'' ones.

So we have a about 30% more power safely.
but you can t have a rule for every engine.Some are much more bullet proof than others.
Evo engines are very strong internally,can t be an example for every engine.
weakest point at oem engines when you want plenty of torque is the rods.Because of antilag, oem small turbos,plus restrictor, they produce a LOT of torque at low-mid revs.
But you can pass it,with a homologation just for new rods.Mitsubishi did it, for evo 8mr-9-10. the ''new'' rods were installed direct from factory at newer models,when they saw that the first batch rods couldn t cope with grN torque.

Thanks Dimviii,
That’s what I’ve thought, the evo engines are very robust already as standard. This what I had in mine when I wonder if standard 1.6T would cope with higher power.
I also read on a site that the standard evo intercooler can cope with 500 hp.

I'm almost sure they are not completely finished.

I heard bodykit and wide suspension would be used for R4T after all.

Scenery is nice, but Rally2's on these type of roads aren't that interesting to watch at least
