I’ve been reading these forums for a while and they have been a great help . I realize my solution is not allowed under the IT rules but maybe somebody can shed some light on the solution to see how viable it is.
Currently I race a stock engine Canadian 87 CRX DX with 86hp and 84ftlb, and some suspension work.

I run in a series called SOLO 1. Anyway, the way our classification has been re-worked the CRX has become uncompetitive so I have been trying to come up with ways to bring the car back to where it should be and stay in the same class.

The solution that I have come up with is converting my car to a SI so I get Fuel Injection. From there I would like to bolt up a ZC head and use the ZC intake and exhaust manifold.

So my question is:
1) Will it work?
2) What kind HP would I be looking at, 110hp, 120hp?
3) Any idea what the compression ratio would be?
Do you know anybody who has done it?


Thanks for the help.
