    yes you can put that head on a b20 block. that is called the frankenstien swap(b20 vtec) because of its low end torque. what you need is a gsr or type r tranny, a ecu from a civic si(b16), b series axles, integra shift linkage or civic si 99-00(will both work.), b-series throttle cable, and b16 intake manifold. b20 intake manifold is too high and will not clear under hood. As far as mounts are concerned, the rear mount and transmission side mounts are the same in 1994-2000 Integra’s and in 1994-1997 del Sol VTEC’s. However, the driver’s side mount bracket is sometimes different between these motors so it’s easiest to use the mount that comes with the motor. A B-series transmission mount will also be needed, and its recommended that you get this mount when locating the transmission. good luck man, you will be very happy with this swap. i planning to do this swap also in my 93 civic but instead of b16 head am going with a gsr head. then am turbo charger it. i can't wait.

    U asked this stupid fucking question before.

    for the last time...

    b20A is off the older prelude from 89-91 not from CRV.
    U CAN NOT SWAP the head over.

    just because it is a B series block and MOST B series engine interchange parts BeSide the B20A.

    get rid of the B20a and get and LS or B20b/z if u want to go LS/Vtec

    i dont know if u were talking to me.
    but i was not talking about how dumb "B20vtec93" was, it seem he know what he is talking about.

    i was talking about the other people who said that u can swap a Vtec head over to a B20A.

    what other people who said you could do that? The B20a is completely different from any other B series motors. There is no possible way to put a B16, B17, B18, or B20b/z head on it. Go read about them in the reference section.

    Wow, I didn't know frankenstein had torque, lets try "because you are using parts from different engines". And next time why don't you try to include some info on generational differences in electronics (distributor, injectors, CAS, IAB) when spouting out halfassed crap, since you have no idea what car it is going into, there could be an easier way. Or maybe you could mention the machine work that is needed, since it doesn't just bolt on.

    actually ludespeed.com did this swap a few years back, they put a b16 head on a b20a block. If I were you I would contact Tom at Lude speed and see if he is still willing to make the kit.

    As I recall though it did not make that much power and the project was scrapped.

    "Sn00za" Have post this before in another place.

    several ppl said that it was the shit and it was all fast and stuff and its call the CRVTEC. they are right but not with the B20A.

    I told "Sn00za" and the other ppl who posted that they were wrong and u cant just swap a B16 Vtec head over to a b20A.

    its not the B20B/Z so u cant just swap it over that easily.

    but maybe he didnt understand or know what i was saying.

    Soo now "Sn00za" post it here and ask the same question,

    ok, lots of crap in here... let's clear it up.

    SURE, you CAN use a b20a block. but you can also use a chevy 302 block and figure out a way to get 2 b16a heads on it if you really freakin want to. ANYTHING will work with enough time, money, and motivation.

    for the rest of us,
    the b20b and b20z are the blocks to use, cuz, well, it fits.

    The B20b with b16 head, june cams, and valve springs extremely well. best thing i put in my '94 Ls. With a little bit of ZEX, it is amazingly fun.

    "what you need is a gsr or type r tranny, a ecu from a civic si(b16)"
    "b20 intake manifold is too high and will not clear under hood":thumbsdown:

    You are giving out wrong or incomplete information...
    His tranny choices are not limited to just a gsr or type r, he can also use the B16 tranny or the LS tranny. An ECU from an SI, GSR, or Type R can be used also. And the REAL reason he can't use the B20 intake mani, is cuzz it doesn't bolt up to a vtec head... :rolleyes:

    His info was fine, not "complete", but not wrong. The type R tranny, is almost the same as the B16 but has LSD, and the LS tranny has longer gearing, so it gives a little on acceleration. The ECU would depend on the head.

    And the the CRV IM is way too tall to fit under the hood, so the bolt pattern is irrelevant.
