I have B16A first gen. and soon will replace the block to b20b. But ihave a few questions. Is the stock B16A injectors would be enough or I have to change a larger one? With all engine internal still standard, what is the safest rev limit for everyday driving so the engine is last long (6000rpms? 6500rpms?)? Is the stock B16A intake manifold and throttle body (58mm) would be good enough?
So far my modification to the car is only i/h/e and crane cams coil. Thanks for the advice.

a 7600 rpm red line should be ok and your b16 injectors should still be just fine.

I don't think that the B20B is a PR3 head design, therefore your intake will not bolt up to the B20B - FYI.

you need to find a Ls intake manifold.

Are you sure I need an LS intake manifold. I have a B16A engine right now. And I just change the block to B20B. Shouldn't the intake manifold connected to the head (B16A)?

Sounds like he's just replacing the block so he'll be running the b16a head w/the b20 block. Just bolt the head on, yes your stock 240cc injectors will work (same as the b20), and your t/b will be fine.
