FD Buyer's Guide
http://rx7.voodoobox.net/infofaq/bguide3g/bguide3g.html

How much Horsepower did the FC come with from the factory?
86-88 NA = 146 HP @ 6500 RPM w/ 138 Ft/lb @ 3500 RPM
86-88 Turbo = 182 @ 6500 RPM w/ 183 Ft/lb @ 3500 RPM
89-91 NA = 160 HP @ 7000 RPM w/ 140 Ft/lb @ 4000 RPM
89-91 Turbo = 200-202 @ 6500 RPM w/ 196 Ft/lb @ 3500 RPM
Infini IV = 215 @ 6500 RPM w/ 206 Ft/lb @ 3500 RPM

Will an FD motor fit in an FC?
The motor mounts are in different locations as well as other issues; however if you have enough time and money it can be done. It is generally cheaper and easier however to put in a 20B (typically around $10,000 installed) than it is an 13B-REW from a FD. http://fc3spro.com/TECH/SWAP/FD3S/rew.html

what is premixing?

Pre-mix: mix motor oil and fuel so that they can be injected into the chambers at combustion time. It is advantageous because the rotary burns a little oil by design. You can remove the OMP to do this, but its not always necessary.

had an interesting problem come up on an '87se i bought for an engine swap.

the girl i bought the car from said her boyfriend tried to start the car one morning and it wouldn't. she brought it to mechanics and they couldn't figure it out. i cranked the car, the exhaust pulse was low so i figured mebbe the seals had blown. didn't matter the motor was coming out and i was putting in a fresh s4 street port engine. paid her $150.00 and went on my merry.

fast forward --> got my motor in and guess what, IT WOULDN'T START! checked vitals; spark, air and gas. gas to the injectors but no gas in the engine. pour some gas down the intake and it'd start right up. looks like a dead ECU right? NOPE!

the injectors we're getting power and the ECU was giving the correct ground pulse. what gives? power and ground = a complete circuit?! bad injectors, all 4? doubtful. i checked the schematic.

then i caught it *** condensor F-43 *** it's official name is Radio Noise Filter ($6.00 part). this sucker is a RF noise suppresor for injector noise. a capacitor directly connected to the power side of the fuel injectors. a little black square semiconductor mounted under the trailing ignitor with a single wire coming off it (F-43). when they go bad, they leak voltage from power to ground = short circuit. but this only happens when they cycle = cranking the car. so that's why i had power at the injectors when i checked, I WASN'T CRANKING THE CAR!

i disconnected the lead and cranked the car - VROOM!. swapped in another and i've been tearing up the roads ever since! ~Rich
