I'm looking at a b16b (ctr) motor (longblock only) for my 95 gsr. is it a direct swap since both are b series motors?

 

Is your motor blown? Why not get an ITR motor?


As far as the mounts are concerned the motor is a direct swap. The only problem you may have is the ODBI/OBDII issue but that will be resolved with adapters or an engine harness swap?

 

I thought a B16 block needs a different timing belt than a B18.

 

Timing belt wont be an issue and yes B series are identically the same. I believe your going to have to change the Block motor bracket that bolts up to the driver side motor mount being that EK and DC/EG are different.

 

Driver side upper mounts are different, as well as intake manifold design and throttle body. You will need an ITR style Intake, throttle cable and cable braket.
