I am building my motor and am needing another crank. I am building my ITR motor for more boost and am wondering is there a difference between a GSR crank and a ITR crank?

If so, what are the differences and since I am building the motor, would it matter which one I use?

THanks

 

Nope there the same nothing speacial, but remember when you get one make! sure its reburished and miced and ready for install, do not buy a used one not knowing if its repairable or not! and stay away from aftermarket cranks they are no good trust me!! oem is the best i know 600+ b series running oem cranks. oem cranks are hard to find sometimes and if you are helpless i have a gsr crank i can get checked and if its repairable its yours for cheap just pay for the reburish so gl

 

actually....the type r crank is heavier. honda added more counterweight to make it more stable at high rpms. you can see the counterweight difference side by side.

i wouldnt worry though, just balance and polish the gsr crank and youll be fine. also less rotational mass.

 

If you're building the engine and dont currently have a crank, scrap either of those options and invest in the LS crank. The longer stroke adds to your displacement and ability to generate torque. Thats just my .02
