I found a Brough Performance EF H2b plateless kit for a good price and wanted to know what problems other members have had with firewall clearance. This kit keeps the h series in its normal slanted position unlike other h2b kits and was told modification to the firewall is necessary. If anyone has had any experience please let me know, thank you.

i have a f20b in a crx the only 2 issues that i have ran into but not a big deal. if your trying to put a oem intake manifold there are mixed reviews about it fitting for example people claim that it will fit but have not yet finished the swap or test drove the car, meaning they have no idea that the motor will swing into the firewall. the first issue i have might be mount stiffness related i have innovative mounts with 95a bushings and my valve cover hits my shock tower so i cut a valve cover up exposing the cam gears and problem solved. second is the crank pulley to frame rail, i put a b-series timing belt washer and made a key way hole to slide it on the crank then a k20 crank pulley, spacer then the bolt.
