Wow, how enlighteningâŚ:sleep:
i thought you were gonna get into power/weight ratio but you didnt even do that?!?!?! I dont see your point 
so if I had 160 HP in my B18A1
ok how much $$ is it gonna cost you to take your b18a from 140hp to 160hp? Now take that $$ and put it into a GSR- spend the same amount of $$ on each car and who do you think will come out ahead?
This is not even taking into consideration the YS1 tranny on the GSR outshines the S1 or J1 tranny in every possible way unless you are FI which this is not a consideration in your scenario.
Iâm sorry please inform me as to why you think the way you do in better detail
also consider how much more the gsr costs to purchase. but dont mind me im just bitter cuz i couldnt find one back then

thatâs true but youâre getting more than just 20hp when you get a gsr. Power everything, sunroof, stiffer suspension, and a higher resale value.
the maximum torque output on the gs/ls/rs tops off at a mere 5K rpm compared to 7k on the gs-r. why is this significant? well on the b18a1, your peak torque starts to drop off after 5k so in actualality, thereâs really no point in revving beyond thatâŚyouâre just making less and less hp and torque. the only reason you would want to shift right at redline is so that the rpm doesnt fall back too low while you shift as to keep the motor in itâs best power range. on the gs-r, it gives the best of both. you get your peak hp and torque at a higher rpm so youâre still making power all the way to 7k. the drop off from 7K to 8.2K will not be as significant as on the b18a (5K-7.2K)and while youâre shifting at this higher rpm, your rpm wonât drop back too low and will still be close or in vtec range. also with the difference in tranny ratios, the gs-r will reach itâs best power range a lot quicker and stay in that range longer than with the b18a tranny. but keep in mind that the comparison is between stock motors but these results will still apply if both motors are modified with the exact same parts.

Now this wouldnât make a lot of sense except the GS-R redline is not that much higher than that of an RS. Yet at the lower enigne usage the RS produces more torque, Iâm not saying itâs faster, but I am after Torque rather than HP. And Iâm also looking to save my engineMy car has never seen the redline
Also someone mentioned somthing about power eveything!!!
If you live where I do power anything=****
When it rains then gets -20 out the next day your power windows arenât going to unroll, there frozen

if thatâs all youâre after- you will never win. You will keep getting beat-sorry.:sad:
Ok psYcoSix you dont think that 1500 rpms is alot of difference in redline levels? Plus during that time is when the car is in VTEC producing the most power and fun:cool:. Also B17 engines were designed to be ran that far or they wouldnt have that high of a redline. Also I never have had a problem w/ burnouts if thats your only reason for this post then i think youâve been proven wrong. IMO

Now a little refresh at what everything is here, we have HP which is the measurement of how much power the engine produces. Torque which is the amout of power appiled to the driveshaft from the engine.
The 93 Integra RS Produces itâs max HP at 140 hp @ 6300 rpm with a redline of 6500. We have a 93 GS-R that produces 160hp @ 7600 rpm with a redline at 8000 RPM. So both max HP gains were below the redline, very little on the RS, and by a little more on GS-R.
Now the RS produces a max torque of 126 lbs-ft (17.4 kg-m) @ 5000 rpm, and the GS-R produces a max torque of 117 lbs-ft (16.2kg-m) @ 7000 rpm. Now with the RS your redline is at 6500 RPM, and you produces power up to 5000 RPM. Now the GS-R redline is 8000 RPM, and it produces power up to 7000 RPM. Now if you find the ratios on engine usage you see that the RS uses .769 of itâs total power (Assuming Redline is the Max RPM), and the GS-R uses .875 of itâs total engine power (Assuming Redline is the Max RPM).
So you can clearly see that the RS uses less of itâs engine power to produce 9 lbs-ft more torque than the GS-R at the max torque RPM. Now I am not saying that a GS-R isnât faster, I am just saying that the RS engine produces more torque than the GS-R engine at the max torque RPM, using less of the engines total power.
no comment.:think:

6500 redline?? I thought it was 6600 on the 90-91 and 6800 on the 92-93⌠or do the US models have lower redlines than the Canadian models?

The 93 GS-R has a lower displacement than the RS, therefore the RS engine will produce more power. If we took and attached trailers to back of the both cars, the RS would win cause it has more pulling power than the GS-R. But if they were going to drag race the GS-R would probablly win cause of itâs smaller displacement. If it has a smaller displacement it produces itâs power quicker, which should in turn make it 1 step ahead of the game.
your reasoning here is way too vague. âthe gsr has lower displacement than the rs, therefore the rs engine produces more powerâ??? thats very general and WRONG! typically less displacement = less hp. You must take into account that the b17a has vtec! dissable vtec on the b17a and dyno it. at that point its essentially the same as the b18a but less displacement, and then itâll make a lot less power than the b18a.
take another example: b16a vs b18c. the b16a has less displacement and makes less hp and less torque than the b18c----lower displacement does not mean you have more power.
Iâve been watching this thread and trying to determine exactly what the point of it is. and thus far iâve seen none. yes, the b18a had more tq than the b17aâŚso? we all know that. but also we all know that the b17a is faster and probably has more potential (to be a high hp streetable motor) than does the b18a.

Isnât HP measured through torque?

And SOL1D your are right, HP creates Torque, but a higher horse power doesnât mean more torque. The GS-R is a perfect example of this 
[/B]
yeah, so what if the b18a produces more torque but less hp?? we all know this. youâre just stating the obviousâŚor maybe there are people out there who need their hands held through reading facts?
âvtec is gayâ huh? thats not something iâd say around here. vtec is not gay, its MUCH better than non vtec. To prove my point iâll use a hybrid motor example: ls/vtec. stock b18a is gonna make the 140hp and 126ft lbs of torque that you mentioned. Slap a vtec head on it (thus keeping displacement the same) and all of a sudden youâre gonna have gobs more hp and torque. vtec adds to the power of the motor by essentially giving you 2 sets of cams.
now, the reason vtec motors have less torque. as youâve noticed all vtec motors have less displacement than their non vtec counterparts (i.e. b18a vs b18c: 1834cc vs 1797cc). Do you know why the displacement is less? honda shortened the stroke in order to achieve a better rod stroke ratio, which in turn allows the motor to rev a good deal higher. In the case of the b18c they also strengthened the block by adding a block girdle. All of this is done so the motor can rev higher⌠in general low displacement motors need to make their power up high. Ever notice how redline on extremely built up domestic v8âs and the such only redline at 6-7k??? they make all their power down low and there is no need to rev higher. with our motors we have to rev them out to make the power (yes, even the b18a is a small displacement motor⌠eventhough it is a little bigger than the vtec engines).
you really need to do your reading up on vtec so you know what it is and what it allows a motor to do. holding all else constant adding vtec will always add more power (hp and tq). also you should look up streetability of built motors. Try building your b18a to be 200whp and streetable (assuming all motor)⌠its not gonna happen, yes, you can get to 200whp but i wouldnât suggest driving it around to pick up your groceries. vtec on the other hand will allow you to have a 200whp all motor monster that is just as streetable and reliable as your stock b18a, and of course MUCH faster.
You are right that many people out there think that vtec already makes them faster⌠but who cares about those stupid people. Anyone whose thought proceses are such are definitely not going to read everything you typed and if they did i doubt theyâd understand it.
and hp doesnât create torque. its sorta the other way around. when they dyno a car or a motor they can only measure its torque. they then exprapolate the hp numbers from the tq numbers. hp is always equal to tq at 5252rpms (look at a dyno graph, the hp and tq curves will cross there).
here is the equation:
HP = (TQ x RPM) x (1/5252)

WOW- thatâs a keeper!!! 
who can argue with such brilliance- youâre basically saying that Honda is wrong in using Vtec on all their high end model line vehicles for the past 14 years- I guess they should have talked to you and your crackerjack staff of Research and Development before they started using Vtec Equipped motors
