Toda B cams were actually rated the best street cams before Skunk2 Stage2 took over. Valve spring upgrades is a MUST.
Use B16B pistons and thinner metal gaskets in your B16A to bring compression to 11.x. To bring out the true potential of high cams you need to increase compression (or else with the use of high cams, your dynamic (or "real") compression will actually be reduced = wasted power & petrol).
Then you'll need a minimum of SAFC to tune it.
If you dont have an ignition timing module, dont bother moving the VTEC point from stock using VAFC. Your fuelling may be correct but your ECU will still be running non-vtec ignition timings.
Best to get e-manage or even better Power FC and a reliable tuner.
Toda B is can be suitable with B16a but not a STOCK b16a. Plus, you'll starve outta fuel anyway because stock 240cc won't cut it.
Instead of buying the (b18) S80 gearbox, I would've asked you to get a B18C block instead. You'll thank me with the amount of torque you'll get and its also a bang of power for the buck.
If you were to use Toda B, here's a few things that you need to consider,
1- Aftermarket valve spring and retainer to match the lift of the cam
2- Adjustable cam gears (proper degreeing to get quality idle and overall power)
3- minimum 310cc injectors or you can get a used set of 4AGE supercharge injectors (those are 340cc)
If you wanna stick with the B16a, zeroed had pointed out a few facts that you need to do.
