Is the GSR engine the same as a LS, but just with greater compression?? Ana are they SOHC or DOHC? Which one would be the best for a mean streat racer/daily driver?

 

There are many differences between the LS engine (B18B) and the GSR engine (B18C1). Much more than compression.

B18C1 has vtec, oil squirters, better flowing head, lighter internals, knock sensors
B18B has a lower rod/ratio, more displacement, less compression

 

ahh what is better a 100 hp motor or a 140 hp motor. hmmmmm

 

Both are DOHC. The GSR engine puts out 170 hp, the LS engine puts out 142 hp.
Both are rated the same on torque at about 127lbs.

 

i think he was talking about dyno numbers, not flywheel ratings.

 

Last time I checked a GSR had 170hp and an LS had 145 or something.

...and what if the 100hp motor had 100 lbs of torque, while the 140hp had 60 lbs of turque. hmmmmm (And no I wasn't reffering this to a GSR in relation to LS or nothing, I just didn't like his response)

 

both are DOHC

 

this was a STUPID question, i thnk every1 on here should know that ALL b-series are dohc

 

 

Yes stupid question but don't all you vtec worshippers go on flaming the b18b saying it has 100hp to the gsr's almighty 140hp... your just a moron too. Dyno a typical ls is has around 120whp, and a gsr 150whp give or take.

 

yea, our ls's are always underestimated. (sarcasm) why dont you get a blow-off valve to go with your vtec booooooooooooooooooost.

 

we all gotta learn some how....

 

the b series are all dohc

Dumb question? I got one... what will it take for an LS to compete with a GSR? I.e., will an LS with intake, headers, cat, and exhaust (Comptech all the way through) beat a stock GS-R?

Thx,
Ben

 

no...

 

Well maybe he didn't know, and he wanted a respective answer?

Dont go underestimating nonVTEC.

 

I've spanked so many gsr's with cocky owners.

depends on the driver, ive hung in with PLENTY gsr's on the street, neck to neck, with my BONE STOCK LS with full interior vs. random gsr's with who knows what they have. after i get the basic bolt-ons as youve stated im sure ill be seeing a few gsr's trailing in the rear view mirror. vtec is not forced induction!

 

 

Assuming equal drivers yes.

Wow, didnt know LS's got a 40% drivetrain loss.

In the real world, where most of us live and race, and GSR is barely faster than an LS. The HP+Torque numbers lie because they do not take into account the torque curve among other things. Its a lot more complex then my GSR has 170hp and your car has 142hp. Like what if the car with 142hp has a constant powerband with a flat torque curve and the 170hp is very peaky with a crappy torque curve.

just my .02, i've spent about the same as your i/h/e would cost you on a act stage 2 clutch and i've beat of gsrs since. the ls losses a lot of power, and my clutch helped out a lot. i didn't even expect the wheel power gain, but i got it. i only put it in because i'm going turbo and i didn't think the exhuasted clutch would hold up to the power. it was a very nice surpise.

 

yes they are both dohc but the gsr is stronger but dont look down on a LS because they have a lot of potential and is capable of doing alot of damage

 

they have too learn somehow, last time i checked there wasn't a knowledge exam to get on this board

 

knock sensors on b18c? really? how do i tell if it's knocking? i heard the engine on another gsr and man was it QUIET compared to mine...(but i think my heat sheild just vibrates too loud...gotta get that fixed)
