for starters im not tall im 5" 11. but i didnt see anything about me not fitting into a hatchback, i just said they lack proportion. hmm..

SOHC = single overhead cam
DOHC= Double overhead cam,

not alot of difference but eh,

theres a fair few performance cars with SOHC engines, dont ask me why though. :)
 
imo, one of the best performance cars with a sohc engine, other then the older usdm civic si's, is the bmw 2002 turbo.

now as to the difference of sohc and dohc.

a sohc engine uses one overhead cam to open both intake and exhaust valves. this design is more reliable and compact.

a dohc engine uses different overhead cams to open the intake and exhaust valves. this design is slightly less reliable due to the more complex design as aposed to a sohc engine but the dohc engine, baring special systems like vtec, has a greater ability to make power under natural asperation. this set up also weighs considerably more then a sohc engine and is larger in size.
 
i prefer a sohc engine in a fwd car. its lighter over the front wheels so the handling is improved. a dohc engine in n/a trim will give more power though. here lays the advantages of a turbo!
 
XD. The poor civics will be torque steering all over the place, with both vtec and a turbo kicking in at roughly the same RPM...sounds like a plan lol.
 
well I think you need to adjust the VTEC or I dunno. I saw somebody with a electronic gage in the car, was called AEM VTEC, can the VTEC be modified ???
 
you cant "set" when turbo boost hits. you need to correctly size the turbo for the engine. for a sohc engine you dont want to go any bigger then, say, a gt28 garret unit. i'd say a garret gt25 would be good.

Stealsoul is an essentially stock '97 Civic EX with the D16Y8 SOHC VTEC. Not as saucy as the B16A SIR-IIs in Japan, but I've walked B16A EK coupes and EP Civic Sis on the autocross course without breaking a sweat. And that's in real life, folks -- no "need for speed" to satiate my appetite for Civic speed.

engine specs dont mean all that much unless your talking straight line speed. you may or may not know that real racing is not done in a line.

at the end of your post you quote someone talking about autox. i can easily see a d16 beating the crap out of a b16 in such racing. the b16 is a very lacking engine. it has no mid range.

Hmm yes i do seem to remember that "real" racing is not always in a straight line - and no i still dont seem to catch that the D16 would beat a B16.

I understand what you are saying that it is lacking mid-range (you cant say it has no mid range) but i dont see it happening.

So why would they have made the EK9 Type-r a B16? especially if an eco model D16 would beat it round a track?
 
because the civic type r's b16b was a de-stroked b18 with race cams. a much different engine then a stock b16a1 which is lacking a mid range.

the d16 is a better engine in that it is lighter, more compact and with similar bolt ons such as intake, header and exhaust it is hardly lacking on the b16 by all that much. now if we were talking b18c, then its a different game. that engine is not lacking as the b16a is.
