Default engine swap help deciding (h2b/b20)

hi people, i want to get a power upgrade into my uk ef crx (already has a b16 as stock)

i can get a racing engined b20 (fully built bottom end+ fully re-worked head with jun3`s and all the bits that go with it ie: block guard etc) then engine is second hand and makes near 260 flywheel hp and 161 lb/ft BUT the engine has not been sleeved, its still using the oem sleeves and its already running a high compression 85mm piston. my fear is if i buy this how long before the sleeves go byebye on me?

the other option im playing with is a h2b swap, its going to cost the same in total BUT i should get the reliability of a stock h22 and then the option of upgrading it later on (smack an accords h22 type r into it maybe?)

what would you do? or should i just get a second hand b16 or b 18 and build one up to my prefrances?

im stuck as to what to do, i need the car as a daily driver (40 miles a day 5 days a week) but i want some more hp and somthing thats more fun, i have been driving b16s with bolt ons for over 3.5 years now and tbh the preformance whilst good it sort of wears away over time.

any ideas or reccomandations?

How much of a "race" engine is that B20? Most real race engines make awful engines for street cars. Their lifespan tends to be stated in hours instead of tens or hundreds of thousands of miles. They also tend to live at high RPM and not be very nice in the lower RPM ranges. (Though 161 lb-ft of torque make me think that it might not be that bad...)

The H-series is a heavy motor, if my reading is correct. (I know, just 'cause I saw it on the Internet don't make it true!) This will affect the handling, and to a lesser extent acceleration and braking. The up-side is that it should be a more robust platform to start with.

It might be interesting to pick up the B20 and either run it while building your current motor for more fun (e.g., forced induction), or get the B20 and tear into it while still driving your B16.

If you need a daily drivable car, I would stay away from h2b kits. It seems like alot of people out there look at h2b kits being to H-series what Hasport kits have been to B-series. And this simply isn't true. H2B kits hardly make for a hassle-free, bolt-in affair. The BIG problem is the length of the H22A, as it is longer than a B-series motor. This, along with the width of the adaptor plate, means that the motor is going to stick out farther on the driver's side. Generally speaking, if you go h2b, you MUST run an alternator-only pulley and NO timing belt cover - DEFINITELY not a good setup for a daily driver. Also, a completely custom hood will be required, as I have been told that even a JDM style hood won't cut it (due to the additional height of the motor). So if you want to run an H22A, using a weld-in kit like Hasport or Explicit would be a MUCH better choice. But B-series would probably be the best way to go in a daily driver, since you won't have to deal with the clearance issues. And you can even run A/C if you wish.

Just keep in mind that a K20 swap is extremely expensive, extremely difficult, and unsmoggable in smog-strict areas. It is also impossible to do certain jobs (ie head gasket replacement and header install) without removing the engine from the underside with a lift. And I don't know about you. But I don't have a lift handy. The bottom line: K-series is more for the rich and daring than the person who wants a relatively cheap and decently quick daily driver.
