Topic: Case switch assembly
July 22, 2019 / By Fidelma Question:
My friends and I have a shop we can borrow to do a swap for a 2000 honda civic ex with the internals done and boosted to 15 psi's. we all thought why not take the motor out and swap it with a new motor but we're not to sure about it yet since we got a lot of money from one of my friend's court cases. well the motor we was planing to use was a F20C (Honda s2000) We never really seen this motor done in a civic and we've been researching it and we're not sure if it would be a good fit since we never really see it done. i've seen one but he said he blew the motor 2 times and the thing is we have a budget we cant go over. do you think this would be hard or easy and how much would you say the F20C motor would cost? and some people think its a dumb idea to make a civic rear wheel drive also but we just want to be a little different than most people with civics around here.

Well considering you have a budget the F20 is NOT the way to go. You would have well over $15,000 just in converting the car to rear wheel drive and purchasing the motor. The motor alone is close to $5,000. Then you would have to channel the entire body from the firewall back to accept the driveshaft. After that the rear differential would have to be custom made because the S2000 has a wider wheelbase than the Civic. So there is the problem of axles having to be custom made, along with mounting issues. The next thing is the motor/tranny mounts. Being as this swap is not done you would have to have them custom made by someone who really know what they are doing because if the angle of the motor/tranny is off just 1 degree, it will tear everything apart. That being said I would suggest getting a B16A from a 99-00 Civic SI. They are readily available for around $1,500. Since you plan on building it for turbo I suggest getting a complete build from the crank up, and also very seriously consider getting it fully sleeved. Running 15 PSI is hard on an engine, even one thats half way built. Go with the Eagle rotating stroker assembly, it has the crank, pistons, rods, and bearings. It will bump the displaement up to a 1.8 liter. Next get a Cometic head gasket, VERY IMPORTANT!! Also a Greddy timing belt. Now for the head. Skunk2 intake, throttle body, stage 2 turbo cams, cam gears, valves, valve guides, valve springs, and retainers. Secure it niceley with ARP head studs. Now for fuel delivery. You will need larger injectors, around 550-750 cc. Upgrade to a walboro 255 lph fuel pump, then an AEM fuel rail, AEM fuel pressure regulator, and AEM fuel filter. Now the turbo part. I would personally suggest either a Turbonetics, or Greddy setup. They have the best products, and warranties. Personally I like the Turbonetics because their warranty covers everything INCLUDING the turbo for a full year from purchase. OK, now the electronics. Get a Greddy E-Manage Ultimate, this is the absolute best unit for the price on the market. Also a Greddy Profec E-01 boost controller will do nicely. Not only is it an awesome boost controller, but you can program the E-Mangage with it too. It also allows you to switch from low boost to high boost with the press of a button. Now all this is almost EXACTLY what I have in my car right now. I have a 99 civic EX with a B16 swap that has been built just like this. I am currently making 367 HP at the front wheels on 15 PSI for eveyday driving, and 497 HP at the wheels on 25 PSI for the drag strip. All said and done I have right at $20,000 in my car total. INCLUDING the cost of the car.
It's been a while since I've messed with this stuff so I'm a little rusty. I could easily be wrong about this but I believe you can go up in years, but not back in years. Example: I can install an OBD1 in my OBDO, or an OBD2 in my OBD1, but not the other way around. You'll have to double check me on that though. I think it's emissions or something like that ... can't quit recall. I know for some swaps they sell a conversion kit that will go from your new computer to you old wiring harness. If they don't .. here comes the wiring nightmare that you never wanted. I know when you go from an older OBD to a newer OBD it'll sometimes require the installation of some new sensors, but I'm not sure about the other way around. Now that I think about it ... did you install a new computer? From what I remember I always heard people took the computer from the donor car and installed it in there's. But like I said I'm only used to people putting newer motors in, not older motors. Hope those two cents helped some. I'd check Hasport to see if they have a premade wiring harness or Google it to see if I could find one.
Keep it simple. if you want a good engine on a tight budget than go with a b16a2 out of the 99-00 civic or a b18c5 out of the type-r integra. Both should work with the right mounts. But if you want rear wheel drive there was this one civic i seen with a nissan engine in it if you wanna try that
