is there any performance gains by switching to a gsr TB over a b16a TB?

 

The gain is not worth the time really... You get a 2 mm approvement but your going to have to take the rotor and spring off the B16 TB for the GSR TB to work.

It would be better if you send out the GSR TB to get bored and then it would be worth it...

Thats just me, good luck though...

 

For the price of boring you are damn close to the price of a new tb. Then you can get it at a lot bigger bore.

 

very little. not worth it imo

 

Is your car stock? Do you have bolt ons? Is it completely built?
Are you able to tune it?
This changes would generally tell us if you car would benefit from a larger TB.
Take a look in the market place. Sometimes you can use TB’s and even bore TB’s for sale.

 

i've heard the H22 TB bolts right up and its the biggest stock bore for b series

 

im not sure if it swaps on, but i couldnt see boaring a TB to be expensive at all ive never had it done to mine but i would of thought like 25 bucks

Not worth it. Don't even bother.

 

both are 60mm

 

h22a throttle body is the same size as the b16a i have a 2 b16as and a h22a they are the same

 

Unless it's a first gen. b16. Those have 58mm throttle bodies. Every other b-series is the same except for the type-r, of course.
