I don't see the need to de stroke and rev like crazy. The 2GR is a big enough money pit so no need to make it bigger! You need 7k+ for dry sump, solid lifters, billet rockers, billet cams, etc. At that stage, buy a 2.8ltr bespoke V8 for $28k and be done with it. Sounds better, costs the same, 400hp/12k rpm.I did some calculations a couple years ago. If they are right you could use the 1gr block or I guess the 2gr also with the 4gr (whatever the 2.5 liter was) crank and you would have a big bore short stroke V6 displacing 3.2 liters. All theory of course bc im not sure if the 2.5 crank can be used in the other blocks. Anyway it seems to me like it would still be able to make big hp and rev like a 2 stroke. Great for a smaller car that has trouble fitting big tires and handling big torque. All theory and dreams of course. Lol
I like the idea of the destroke but even to get to the stage I am at has taken a huge amount of energy but a de-stroke would be more for less power so it really isn't where I would go.
