I was just wondering if anyone out there ports etc or know someone that does fairly reasonable priced. I already have the block intake etc but I'm not using the head or internals from the donor engine so I have to pick up a head from the j/y and I'm going to have to get some rods/pistons made. I want to build the car with as much horsepower n/a as I can. I'm hoping for numbers somewhere in the 180 horsepower range or so which shouldn't be a problem from what other people have done to their 4 cylinder fords. I'm using a Ford 3.8 55mm throttle body which should be plenty big enough and running some 5.0 yeelow top injectors it will have a MSD DIS2 ignition etc an a/f meter and controller as well. My money is tight at the moment with automotive school being a priority and all so I'm getting things slowly. I already have the tb/intake/injectors/block the rods are the same length as the Zetec rods so I don't have to get those custom fabricated but the pistons will be a problem. I'm wondering what type of c/r I should run it's stock 9.2 :1 I'm thinking 10.5:1 or even higher possibly give me some ideas if you actually took the time to read this long ass post lol.
Oh I'm also doing an adjustable cam gear and UDP with overdrive pulley for the alternator as well as a CAI, a 4-2-1 header from a 1st gen Escort GT 1.9 which just needs to be port matched a little and a 2 1/4 inch mandrel exhaust with a performance stock looking muffler that will hopefully give it a deep note and not a fart racket.
What do you mean hasn't been done before? The SPI is basically the old CVH motor...tons of aftermarket. Do a search on Yahoo, you should find some info there.
BTW...it may just be cheaper to dump in a DOHC Zetec.
