Which is faster? A stock FD Civic or a B18C2 EG?

Comparing the K20Z in an FD:

K20Z2
Displacement: 1,998 cc (121.9 cu in)
Compression: 9.6:1
Bore x Stroke: 86 mm x 86 mm
Power: 155 hp (114 kW) @ 6000 rpm (SAE net J1349 Rev 8/04)
Torque: 139 ft·lbf (188 N·m) @ 4500 rpm
Redline: 6800 rpm

And the B18C2 in an EG sedan (balance the weight issues out)

Displacement: 1,797 cc (109.7 cu in)
Compression: 10.0:1
Bore: 81 mm (3.2 in)
Stroke: 87.2 mm (3.4 in)
Rod Length: 137.9 mm (5.4 in)
Rod/Stroke Ratio: 1.58
Power: 170 hp (127 kW) @ 7600 rpm
Torque: 128 lb·ft (174 N·m) @ 6200 rpm
Redline: 8100 rpm (Fuel cut-off @ 8200 rpm)
VTEC Engagement @ 4400 rpm
VCIS Engagement @ 6000 rpm

Then calculate the curb weight (EG is 1144kg, FD is an estimated 1300kg)

So the EG has 148hp/ton and the FD is 128hp/ton. For torque the EG has 152N.M/ton and the FD has 138N.M/ton. On paper the EG would eat the FD2 on the straights in pure power-to-weight ratio, but when it comes to cornering I think the FD has the upper hand, due to stiffer chassis and a modern suspension setup (independent rear wishbone suspension and a much better Macphearson struts up front).

more modern suspension setup? WTF how do you call macpherson strut a better setup than double wishbone suspension??

Hondas went backwards after the 2000's in terms of suspension design. Look at a new fn2r. Torsion bar rear end. Really modern. Sporty too if your comparing it to a swift sport. Ef/eg/dc/ek hands down best tuning platform Honda has ever released in terms of suspension and ease of engine swaps

Sure, in terms of pure design the macpherson is a lousier set up than a double wishbone, but with modern tuning and stiffer chassis, results speak for themselves: FD2R is faster than an S2K on Tsukuba and just a bit slower than an NSX Type-S. A Mugen RR is only a 6th of a second slower than an NSX Type-R. A FF sedan with shit power catching a MR supercar (Source: http://www.fastestlaps.com/tracks/tsukuba.html)? Shit is unreal, there is potential in the FD2's suspension/chassis setup.

an FD2 or a FD1 is anything but a FD2R.... suspension design may be similar but the FD2R is tuned and the FD's aren't

Yeah but the point is there IS potential. An FD2R compared to a DC2 Type R is faster around a circuit, despite being heavier, nearly the same power, and Mac struts up front. I was at a wet skid pan day with some friends, and a modified Evo 8 was easily the most rated car there...but did it get the fastest time? Nope, it was an 2L auto VRX Lancer (current gen) that won. Driven by a girl. By 3 seconds.

lol look at what your quoting, the mugen rr, a civic with a major tuning company backing it, doing major work, is still slower than a STOCK 97 nsx r and a STOCK 01 nsx type s.

Yes it is fast, by all means, but like all designs has its limitations. And you keep going on about this whole stiffer chassis thing, at the end of the day when its a race car they all have a weld in cage, and there once again comes limitations to how stiff, and you will see where the suspension is flawed and limited.

If you want to bring tuning company cars into it, ummm spoons street legal k20 ek9 runns 1:02s and so did their b16b ek9 with 1800cc stroker and that was way back in 97'

yes the potential is there, no you will probably never have the money to do the rnd mugen did to their civic to make it that fast.

And thats because the owner of the evo 8 probably couldnt steer to save himself. At the end of the day you could own a ferrari fxx and still be beaten by a stock car if you dont know how to drive.

And with that last point i'd suggest to you (before you waste any more money on your eg sedan on seats) to actually take you car to the track and see what you NEED to improve on your lap times at wakefield instead of reading on the internet that an fd2r with its stiff chassis makes such a good base for a circuit car, and thinking hmm if i put a million braces on my sedan i'll be as fast as an fd2r.
