Personally I think the B20 bottom end is great for a basic street setup. I’ve never lost one I’ve tuned with boost, but I don’t get greedy.
I wouldn’t hesitate if you want around 300 whp or less on that stock b20 with vtec head combo with arp studs and a metal gasket.
I tuned a kid from rochester running a B20/B16 with both parts stock except for gasket and studs. It ran 11’s, made 390 whp, and he ran it for 2 years and sold the engine to someone still running…so I know it’s possible to make more. That particular customer told me to push it and he didn’t care if it blew since he had several other cars. I don’t recommend pushing the stock shortblock that far, but they’re not junk.
If you’re looking to have one sleeved and built up we can do that too.
