PLEASE, let's not say that it will "easily fit an Alpine". I have been thinking about the Quad4 engine swap for about 6 months now. The engine is tall (for a four cyl) and may not clear the bonnet. Since the only Quad4 engine that I own is the one in my GTZ Beretta, I can't be sure of the fit. If I can find the time, I'll try to get some measurements on the engine height. I'm pretty sure that the long, intake manifold runners will not fit inside the Alpine engine compartment. The original computer, from a Quad4 vehicle, will need to be included in the swap (computer controlled ignition and F.I.). I see it as a very challenging engine swap; Much more challenging than the Ford V6 swap.
