I'm planning to get either those. Basically both are bolt-ons and ready to go without tuning. Which will have more power, a greddy at 6psi or JRSC with 6lb pulleys? JRSC seems to be a bit cheaper than a greddy with IC and upgraded fuel pump. Just wants to know which one will give me more power. Anybody have experience with either for the GSR. Dynos would be nice on the Greddy kit also. Advice will be greatly appreciated. and no I don't want a Drag or revhard or custom make a turbo kit.

Greddy will

 

Ready to go without tuning? Not so sure about that....

I don't think the difference in power is what you should be considering when looking at supercharging vs. turbo. Boost is boost, but they're both different routes. I personally would recommend the greddy but if you give us more info on what you're looking for then maybe we could give more concrete reasons for getting one over the other.

no "real thought processing" tuning

i just want something that will be fast, but no need for a larger turbo like drag or something:dunno:

 

The GReddy kit for the GSR isn't really that small. In fact if you get the intercooled kit you don't have to do any less work than if you bolted on a Drag or RevHard kit (as in, just install what comes in the box).

The JRSC runs less boost so you can get away with just running an FMU and MAP check valve and be fine. But to get any sort of boost setup to be truly RELIABLE you'll actually have to tune. Ain't no way around it, sorry.

 

The quality of the greddy kit is :thumbup: Everything fits so perfectly. Mad props to greddy in their designing. They even make the oil return so you dont have to weld. Drag and revhard usually have some fitment problems plus you gotta grind the block a little on most b series kits. I'd go with the greddy but im a bit bias. Tuning is always good if you want your motor to last. The greddy blue box is eh....I'd change it out asap.

 

greddy by far... cuz i won't install the jrsc for you
