This should be a fun excercise for some of you real brains out there...

I have an obd0 integra. Looking for an engine to pop in her, but thinking separate parts may be the way to go. I've wanted to build an engine for a while and I have the following parts:

- 2 x b18a complete engine w/ manual tranny (including what's in the car)
- p30 w/ pw0 plugs
- 99 si b16a intake manifold, throttle body.

I have easy access to the following parts:

- full GSR head - loaded
- full b16a block (no pistons or rods)

So.. first - please don't suggest ls/vtec, as it would require either burning obd0 roms or converting to obd1 and buying a hondata, due to the knock sensor issue. Next, a couple questions:

1. Is it possible to use the b18a pistons / rods or am I looking at sourcing either b18c or b16a pistons / rods? If the latter, which? If either, which gives more power?

2. Although I have the crank from the b16a, could I use a b18a or even a b20 crank to make better power, if at all?

If your answer depends on the long term goal (FI vs. NA), it's all motor.. maybe with nitrous at a later date.


Thanks in advance. Creativity welcome!
