F20C or Beams?

[Dimitri]

master tech, cool.

im not formally trained in anything, but i'd still never space the sub frame 1.5" to fit any engine to any 86 under any circumstance.

im willing to say, maybe the f20 is faster. because ive never been in an 86 powered by one. or an s2000 either. going off the factory quoted power and torque figures, i dont see there being a huge difference, but maybe a noticeable one.

the info i can give is that the beams engine made 175hp at the wheels, on the same dyno, an ae101 20v will be lucky to make 120. (both in ae86s)

what i can say for sure, it is no more necessary to space the sub frame when fitting the beams as it is the f20. both are tall motors, and large gearboxes. though the f20 box quite a bit bigger than the az6. the further back you push the engine, the more clearance you gain with the bonnet (hood) as it is sloped at the expense of necessitating transmission tunnel modifications.

edit- re weight, i dont have any numbers specifically for engines. but i just checked with ant. and his car (jdm trueno, coupe) with beams was 881kg.

frp bonnet and boot. stripped interior, sound deadening stripped up to front seat tie rail, and also had the dash and headlight looms removed. normal windows, larger diff, big ssr 15s ect. apart from the head light dash loom, a fairly normal privateer drift car.
