I'm putting a b18a1 in my 97 civic lx and was wondering if I could use my stock Ac bracket mount and front tranny mount

 

you can use the rubber, but not the actual mounts on the motor/transmission.

 

Does it need to come from a 99 00 si?

 

It depends. You can use a 99-00 Si one if you're using a B series AC compressor. If you plan on reusing your D series compressor, you'll need the bracket/mount from a 97-01 CR-V or any Del Sol with a B series engine. If you plan on running without AC, you can use any of the above.

As for the front tranny mount, I'm not 100% sure on this but I believe the 99-00 Si or any Integra one will work. I'm not positive on that though. Been quite awhile since I've done a B swap.

 

as far as mounts you can only use the rear mount and trans mount you need to get the T bracket from a civic si and the driverside mount off a civic si and you can use your d series AC comp as long as you get the del sol (vtec) bracket or crv bracket

 

Ok thanks for the info. Do you know of any cheap websites to get the bracket from besides eBay?

 

And what year of del sol had the b series

 

Just 1994/1995 in North America. There were also D series Del sol's in the same years so if you're looking for one from a Del sol, make sure it's from one with a B16.

 

You should easily be able to get a 97-01 CR-V bracket from a junk yard.

 

Ya I made that mistake of buying a non vtec del sol bracket
