    I have a 1991 civic DX hatch, with a B16a in it. I would like to put a header on it but I don't want to hack my front lower subframe to bits so it will fit. Is there any other solution, i have tried to see if there is an aftermarket subframe to compensate for this but I have yet to find one.
    Any suggestions??
    Thanks in advance.

    jimfab and z10 both make an aftermarket front crossmember, but they are kinda pricey, 350 for the jimfab unit and even more for the z10 unit. but i think the jimfab is a better design anyway.

    heres some links:

    www.jimfab.com
    www.z10eng.com

    if you want to wait you can sometimes find a groupbuy and get things for cheaper. i got a jimfab for my crx for 280.

    WhiteWRX02 has an 91 dx hatch with a b16a and he bought an OBX header and we didn't have to hack anything, it fits perfect. DC sports might also fit, not sure.

    Goodluck B)

    u will probably have to hack the subframe if u get a 1 peice or a 4-1 header, if u get a 4-2-1 2 piece header it wil most likely fit.

    check out the classifieds section of honda-tech, I saw a group buy for what i think maybe a jimfab, or maybe some other guys front crossmember for crx's and 4th gen civics. he had a lot of vouches for himself, and the price was a little better 270 i think for the cross member.

    I have a 90 dx and I just put a 4 into 1 dc header for a 2000 si on my b16a.
    It fit without any cutting, In fact, props to DC for such a nice fit, but I am going to change my crossmember to a place racing crossmember so I can take advantage of a front mount and a lighter crossmember. I have seen these on ebay for $200
    item #2430374497.

    i would stay away from that place racing bar. looks like it eliminates the radius rods on a crx. which help reduce wheel hop. doesnt look that strong to me either. just looks like poor construction to me. go with the jimfab bar. excellent design, has beefier radius rods, well constructed, and is much stronger then the stock unit.

    I can't speak to the construction because I don't have one in front of me,
    but it does have mounts for the radius bars, you can see them in the photo.

    I'm curious as to the Jimfabs weight, it looks stout, but it looks heavier than
    the stock crossmember. If it is solid bar stock it probably is heavier.

    :werd: you dont need the front mount if you have good mounts like hasport. imo place racing blows. they used to be good, but their reputation has gone down hill. the products just arent great quality. and i dont know about the weight of the jimfab bar. i know the main bar is chromoly, but i dont know how heavy that is. and why would you want to keep the stock radius rods when you can get beefier ones from jimfab or z10. and imo jimfab has the superior design for its function.

    Hasport mounts are great, I have them, but just because it works
    doesn't mean it can't be better. Honda/Acura designed their motor
    to have 4 mounts. Trust me, if they thought 3 mounts were sufficient
    they would have saved some money and done it that way.
    Hasport beefed them up to handle the added stress, but all of their
    mounts still use the same bolts and brackets that stock mounts do,
    so they haven't changed the load capability, only the ability to handle
    greater stress from the vibration of only having 3 mounts.
    Like I said it works but it isn't the best setup.

    honda/acura designed their cars with 4 mounts for stability of the engine. BUT they have to use rubber mounts becasue of the geometry of a inline 4 engine. inline 4 engine causes a lot of vibration. the following was taken from a pinned thread in the General Tech Forum found here-> http://www.hondaswap.com/forums/index.php?...showtopic=13781 to prove my point:


    now, the reason why hasport only uses 3 mounts is becasue they use solid mounts. with the extra stability of their mounts, the 4th is unneccessary. Hasport's 3 mounts hold the engine stiffer then Honda's 4. and although this will cause some vibration in the chassis of whatever car this is in, we as tuners can accept this for the gains in performance.

    ADDITIONALLY, that bar is made by place racing. hence it will be designed to work in conjunction with the place racing mounts. and since the mounting position IS different between the hasport and place racing mounts, i highly doubt that it would even work in conjuction with anyother engine mounted in a crx using mounts other then place racing.

    please dont talk shit if you dont know what you are talking about. thank you. drag through :burnout:

    I am pretty sure you didn't read the thread you call your "proof" bozo.
    The thread is about stiffening the front and rear mounts in order to tranfer torque to the wheels. Try reading the whole thread. I am hoping you can read. Obviously you can sound out words but your comprehension sucks.
    No where does that thread say you gain any performance by not having a front
    mount. What he says is that you stiffen the front and rear mounts to increase
    torque to the wheels. Not get rid of one of them.
    Why do you think they use a higher durometer for racing mounts.

    Can you say "durometer"

    Howyousay
