Ok. Bought my first honda it's a 1999 Honda Prelude base model. H22a4 automatic transmission (Don't judge manual users) has a rodknock. Heard f20B is literally plug and play but don't believe it. My first engine swap ever. Is there a step by step guide? Or can I just drop the engine in and use the h22a ecu and plug it right up? Thank you.

lol first off with 90s hondas and even to todays standards the manual is far superior to not only make power but for gearing , 2nd yes it is a direct swap motor physically but it does use a different ecu and has less power, have fresh rod bearings installed in your current motor or buy another H22 , H22 is a better motor

I'm making it my regular daily. I have a manual project car. (89 Supra) so I know all about the manual life. I'll look into bearing replacement if it's cheap if not I'll just continue with the swap

Well, it depends on which F20 we're talking about. There is a dual-cam, VTEC F20B that's basically a destroked H22. Horsepower's about the same, slightly less torque. If you can get one of those for cheap, it would be a decent replacement for the H22. If it's a non-VTEC dual cam or single cam though, then yeah, it's going to be disappointing compared to the H22.

he also from understanding doesnt have a dohc f20b vtec he said HE HEARD its plug and play, if auto id say best bang for buck personally would be to like I said throw rod bearings in existing and if not replace with another usdm h22 , IMO
