I'm an LS fan. Straight out of the box. And if there is one thing I hate, it's having to go on the defensive when some VTEC nutjob starts rolling his eyes at me cause my engine isn't the almightey vtec. I could never justify the reason to spend 2,000 dollars on the GSR motor, when an LS motor could be had for much cheaper. I finally just busted out the dyno charts, so maybe even one more person will understand why the GSR motor aint' all that great, or, not worth the extra 2 grand anyways. Here we have equally modded (basically stock) LS and GSR motors If you are so kind as to notice, the GSR and LS motors are ALMOST EXACTLY the same, up till about 5.5 grand. interesting, eh? And if you notice the rest of the dyno chart, that extra 2 grand you spend on the GSR gives you a whopping Burst of a tire melting 20 hp (for about 1.5k RPMS, at the very top of the rev range) wooo! 2,000 dollars for that. Below I have given a nice cost analyzation of the dyno charts. And yes, I know the GSR does come with some better parts on/in the engine. But c'mon. We all know they aren't worth the money. And as for the difference in track times, that can be accounted to the GSRs shorter gearing, which on the other hand, is quite an advantage over the LS. If you still want to pay that extra 2gs for the GSR, be my guest. But I just thought I'd shed some light on the situation, as to save an unsuspecting engine buyer some dough. For that extra 2 grand you could have turbo. And then, for the same price, the GSR would be miles behind. Thats all. And just so you all know, my company convieniently paid me to write this, make those images, and they are "graciously" hosting the images also So thank them, lol. Feel free to comment and/or point out that you think I'm wrong. Adios.
