I know this post is ancient and dead, but yeah, ive done it. Hence the user name. I ran carby for a while with the pressure box setup, then scored an N13 injection setup, and custom made an intake plenum. Only ever put 3 or 4 pound into it, but you could really feel it :y: . Ran an IHI RHB5 off a 626 turbo, and did all the fab work myself. Would have cost me less than $200, and was well worth the price. Sold the setup ages ago. Anyways...
