about 3cfm at high rpms. Loses mid range torque compared to a gsr head. They are called a "Poor Man's Type R". If you have a Gsr complete, don't waste your time and money on it. But if you had both, and just felt like making a little more power, then take the cams out of the gsr, put them in the b16 head, and then put the b16 head on the GSR block. If you don't have it, then don't worry about it.

Well, if you have a gsr motor already, I wouldn't swap out the gsr head for a b16 head. Sure it flows a tish better at high rpms, but you will loose .2 compression and therefore loose power. Spending the money on different pistons/headgasket/ect would make the head swap pointless just to get back to gsr hp/torque.

But, if you have a b16 motor, swapping the smaller b16 block for a larger and stronger b18c block is an excellent mod, called the poor mans type r. Yes, you will still loose .2 compression and not make quite as much power as a gsr, but if you use your b16 pistons, you have relativley the same compression and be making a lot more power than a stock b16 for sure, and more importantly, gain low end/midrange torque.

As for LS/Vtec vs. Poor mans type R, the LS/Vtec will probably make more power if done right, but is a harder conversion to do. The gsr block swap is a direct bolt on.

cheap if you find a block and you find a b16 head.
