It's not exactly that one is "better" than the other.

If you take a plain old JRSC and install it on an LS, you won't get much of a gain. Maybe 30-40 hp tops. If you put a JRSC on a GSR you will get much more of a gain and have an insanely linear torque curve. So, people will say the GSR is "better" than the LS when you slap on a JRSC.

Now if you take the same turbo kit and bolt it onto an LS and a GSR, the GSR will still make more power. The tradeoff is that since the GSR has a pretty high compression ratio, you're more likely to blow up the motor than with an LS. That and you have more of a safety margin with the LS's lower compression. Still, a GSR running the same boost level as an LS can typically make 40 to 60 more hp at the wheels.

Basically with an LS the JRSC doesn't provide enough of a gain to really make it worth it, while a turbo does. The GSR will always make more power though.

 

GSR w/JRSC in my opinion is pretty damn fast...but runs out of breath at top of 3rd.

 

Mate your LS head to a b20 block after you have street stripped ported/polished. Upgrade the crankshaft, rods & pistons to bump up the compression to 2.0 which is what your bottom end will be. Add some crower cams and you'll have the all motor torque your looking for. Or you can go forced induction, both are costly and best would be to turbo the b20 setup but that will definitely set you back. It is always better to force a "built motor" as opposed to stock. Hope this helps.

 

The way to have more power down low without FI is to have bigger displacment. As in boring it out to a 2.0 or just buying a B20 block

 

I gonna roast him, makin fun of non-vtecs. Buddy, all u need is a crower 403 or 404 cam to get the same or not if better efect then ur Vtekkkkk. 170 at the wheels is easily doable with a LS non-VTec! And the LS motor has a stronger block then a GSR.

And the amount of money required to get to the point of a GSR in terms of power isn't worth it. Go with the quicker car to start with and get bigger gains.

 

LS VTEC homie is the way to go.. juss swap out ur ls head with a GSR head garantee u'll be spankin GSRz with ease.. and type rz dependin on how good with the setup u can pull off.. but the thing is.. the ls dont have vtec.. good news is.. they sell the fittinz and all the requirements for the setup now..

not true... if you find a gs-r swap for 3000$ thats 3000 you could have put into your LS engine to far exceed the power that the gs-r will have.... then you take whatever additional money and you keep going further.... sure, if you have a b18c1 at your convinience then yeah, its is preferrable to the b18b but if you have a 5k budget, put it all in the b18b and make more power than 3000 for b18c1 + 2000 for modifying...

 

:thinking:

nah, ill keep my mouth shut...
