2150 Kit + I-Beam Connecting Rods - TODA Racing USA / MISANO Motor Sports, Inc.

So, I been looking @ this kit for some months (leaning towards 2107cc displacement)
Has any1 in the forum attempted this?
I'm very intrigued when it comes to rotational mass reduction & curious how much will this help for response, acceleration, & hp & torque output [to the wheels]

For $7k there must be thousands of other options out there.

What about a oversquare motor? 89mm pistons?

If you're truly interested in a good stroker kit that will not absolutely empty your bank account, I suggest you PM k20z3allmotor. Are you located in CA?
lmao at $7k, you can get a turbo kit and tune for that and make 460-480whp
The site was just a reference containing info of the stroker kit. I am able to get Toda Stroker Kit for half the price that's listed on Toda's website

is k20z3allmotor on this forum?

He is just the fastest all motor 8th gen in the world, no big deal.

Yes....he is on this forum and youtube as well

Even at half price the toda kit is a waste of money. If you are looking for more cubes but high revs it would be cheaper to destroke a k24 block...bore it over and then rev the piss out of it.

Most will build a k25 and still rev fairly high while making a ton of torque over a k20 block.

Keep in mind that fully counterweighted cranks help keep the vibrations down at high rpm. While some may knife edge the cranks I wouldn't advise that for a street motor. 4 cyl motors aren't very balanced to begin with and an engine spinning to say 10-11k rpm would have issues running that rpm on a knife edged crank for daily duty.

A solid forged full weight crank may not be as responsive but unless your building a race car I would stick to a nice oem crank. The aftermarket stuff is $$$$$ but race cars obviously get more high dollar parts.

Response is mostly for road racers....for street duty I would imagine longevity being a bigger concern.

Do you plan on yearly rebuilds?

Very well explained, I am reconsidering
You made a good point about high rev (10-11K RPM), I had no idea it would vibrate the block w/ a knife edge crankshaft. Some months ago, my plan was to have my internals fully Toda (except for cams, JUN Type 0).
I'm intrigued in your response to this stroker kit I brought up, & base on that I will go as far down as changing Pistons & Rods, keeping that crank OEM

Before I planned on Toda 2.1/2.2 Stroker Kit, I had intentions on mating the K20Z3 head onto the K24A2 block, but I didn't go through w/ it because it would reduce my rev limiter to let say, the 9thGen Si. That's why I posted up this stroker kit to find other variables that would affect the DD.
