hey whats up yall, well i've been thinking about this swap for awhile now and all my friends say Its stupid, Its Gay, Your Dumb. well anyways i was thinking about taking the "B21B?" out of the 88-91 Prelude Si's its a DOHC 2.1L non v-tec motor and they are already obd0 so there shouldn't be to much to mess wiht, and i think all you should have to do is get some hasport B-Series mounts and a cable B-Series Tranny and i think maybe i mite be able to use my Si harness in my car. this mite be an easy swap but who knows, so i just wanted to know yalls inputs so let me know what yall think ? ?

 

that motor is not the best building platform. I guess if your doing it to be different, then it maybe worth it. I'd rather buy a b18a or b20 if I was going that route.

 

well why would you say that?

 

nothing new about this question.....but that swap would suck *****.

 

or so I've heard.... "that generation prelude motor is GARBAGE"

 

first off you will have to find someone to make custom mounts for this engine... second this engine is a lot heavier than any of the other b-series engine... and last this is just a bad engine platform to start..

im not saying its not possible, but IMO you are better off getting another engine

 

well its not a motor i was gonna put in my car i just wanted to know what yall thought about it, THanks

well...... is there anyone that has tried this swap??? ....... no? i think if u got the time and money go and do it.... than let us know if it is worth it or not....cause i have not talked to anyone that has done this only peeps that have heard about it....so go do it and good luck...

 

Better find someone with good fabbing abilitys, that swap would not be logical imo, and plus the wiring i think is totally different.
just my .02.

I hate the word Preeeelude!

 

from what i heard the motor in the prelude even though it's block # is b whatever
it has nothing in common with the b16 etc. its got more in common withe the f series motors if i'm not mistaking wich means it would probalbly be just as hard to do an h22 without the power or parts availability

 

Yeah, it's a "B" engine in name only. It's not really part of the B16/B17/B18/B20 family most people are familiar with. Same way with the '84-'87 Civic/CRX "D" engines. Sure, they're D-series... kind of... but they don't really match up or swap out with much (except the 1G Integra's D16A1).

There's a reason no one does this swap (old Prelude engine into CRX/Civic) or talks about it: it's not a good swap. If you're going to go to the trouble of DOING a swap, you want to actually gain something by doing it, other than the experience of just doing it. These engines made - what? - 130hp on a good day? Why would you go to all the wiring/mount/fab/tranny/exhaust headaches for a measly 130hp, when you could do a simple ZC drop-in using all your existing mounts/tranny/wiring/exhaust, etc, with a couple simple wiring changes, and get the same power? The reason people do swaps isn't just to do them or to be different; it is because there are better drivetrain options that offer more power for a given amount of money. The ZC swap used to be very common, then the B-series swaps started to take over, and now the K-series are starting to happen. In each case, there are specific gains to be had relative to the amount of work and money spent. ZC = pretty cheap, for not a big gain. B-series = a little more money for a good chunk more power. K-series = a LOT of money for a TON of power.

Know what other swap I never hear people talking about? An '86 Ford Escort engine into a CRX. Maybe you don't hear people talking about it because it's just not a good idea... But if you REALLY want to drop a Prelude B-series into your car, go right ahead.
