20b in to FC
 
How much am i looking at to put a 20b into my 86 fc. I'm not looking for the best 20b out there. the cheapest ggood running engine is more like it. Turbo is not important. I just want to know how much i would be looking at for a price range. oh and About how much power does a stock 20b put out? any info would be great. thanks.

you have to bang the firewal back like 2 inches, and make custom mouts for you rack and pinion and a whole lot of ogther work, Its alot of work and VERY EXPENSIVE.

Officially 280ps or a little over 270bhp...

Run it NA - engines can be as cheap as $2,000 shipped to your door.
There's a $1,500 one that someone spammed all the sections in here recently.

Mounts from K2RD or FC3S.Org are $250 for the pair.  If you can make your own, go for it.

You can't use the NA clutch, as it's going to roast it in very little time.  You're going to need a clutch kit and flywheel if you're going to do a 5-speed manual trans - the Cosmo 20B only came in auto trans option.

The stock ECU can be used when reprogrammed by Corksport.  Of course, this requires the stock wiring harness and coil packs - both are rare.

This requires a custom exhaust manifold, but if you can do this it's not a big deal.

I really do not recommend to do this cheap - it's all going to bite you in the ass in the long run.
