Sohc Or Dohc Wich One's The Best
 
HI i have a 94 Pro DX SOHC and i want to put a new motor in it and i was

wandering wich one's the best SOHC or DOHC..now i asking this because my bro

have a 98 Pro DOHC and i beat him ( not by much though) so does it really make a

difference ? ( my car and is are tuned almost the same )

I know DOHC is supposed to be better, I forget why though, somthing to do with the engine running more efficeintly etc.

Yes the DOHC is better. Your brother's car is probably a 1.5L compared to your 1.8L.

Just when I think there is no smaller engine there is a 1.5, man i thought my 1.8 was small.........hmmmmmyou think I could fit a manual transmission in my car cause thats what i really want is a manual.......I would keep the car if I had one.....

Mica94Pro May-12th-2004 02:07 AM

no is engine is a 1.8 DOHC

the dx is only 103 hp, but it puts out more torque : 111. the lx puts out more horsepower to the flywheel 125 but the torque is 114. which is pretty close to the dx. Plus the lx weighs 100 lbs more. not that the weight difference matters very much.
but torque..-the power thats put down to the wheels right?
They say "Power is what you read about. TORQUE is what you FEEL."
I say the better driver wins it.
But then again, i could be wrong. i hope what i said made sense.

TaiMaiShu May-12th-2004 09:59 PM

oh yea...but then again..you have different transmissions. right? so different gear ratios and acceleration patters. and different redlines. maybe i don't know what i'm talking about.

kenspro May-12th-2004 10:22 PM

o I'm sorry I thought you meant it was a 1.5 my bad but uhhh yeah I am going to try to get a new tranny later....

Yeah it's a different year so...and my car and change a couple of things to get 100km/h there faster , i've change the tires size usualy it's P175/70/R13 now it's P175/80/R13 i loss acceleration but i have more top-speed so 0-100km/h take me 11sec. instead of 12.5..... yeah and is red lines starts i think it's at 6000rpm and mine start around 5000rpm well that what i think...

no, the 90 to 94 models have the exact same specs. and you dont redline at 5k, its 6k. his redline is 7k

( my bro's car is a 98 so it's differents specs ) and if my red line is at 6K how come the rev-limiter kick-in at 6 750 rpm ?

sometimes the rev limiter/speedometer can be off by a little bit. but i think that sounds about right. still though...take it to 65oo.
