i was thinking of getting an RSM stage 2 supercharger, JBP stage 2 cams and a 62mm t/b. I was just wondering what kind of results i can expect from these mods and if it is even worth it or if i need to add something out to get better results.
id get the adjustable cam gears to and tune it all together on a dyno with boost you want a hair overlap i believe
04 sunfire auto 16.3@82.5.................for now
but that also means that ill have to get rid of my intake right?
yes it does. the rsm kit comes with all of the piping that you need. to put in place of your intake.
I just thought of a question at work today......i know that with a turbo when you hae a lower compression ratio its better so that it can suck in more air, but with a super is it better to have a higher copression for more power since it runs off the engine? "just wondering its been buggin me"
damn and i just bought a secret weapon too.
Hey man I have the RSM stage II kit and more on my 04 cavi. I also have cams coming from Crane Cams bought from GM Performance and custom cut by Crane. I got the cam gears from GM also. If ya change the cams you need to get the cam gears too. As for the kit if ya got a question on it ask me. I've had it for a whole year. The only guy within who nos how many states to have this system in a 2004 cavalier. Now I've never heard of JBP before. Are they a reputible company? If not I know crane cams is. They've been doing it for years. Plus the Cams from GM performance are not that expensive. The cam gears are alittle pricy though. The ones I got from GM were blank.
As for the stage II kit. It comes with a 62mm throttle body already. Along with a Ported and Polished head, Custom piping for the intake, Vortech V1-T Race blower, Vortech blowoff valve, HKS filter, K&N breather, vacume lines, Batterie relocater, and software. When I bought the kit it was $5900. I'm not sure what it cost now. Also if you go to there shop and have them put it in they'll pay for your hotel stay. So if ya do get it take the time to go there and let them put it in. You won't be disappointed.
If ya get any questions you don't wanna put on here email me at vengeance_racing1@yahoo.com see ya later. Peace.

rsms kit is 3900
but it doesnt have the head or the t/b. have you had any problems or complaints about any part of the kit? any cels? did you do the install or did rsm?
soo no one knows the answer to that?
I have had a minor belt issue and yes my check engine light is on. But as I said I didn't just do the stage II kit. Oh and yeah your looking at the stage I kit not the stage II. The stage II comes with everything I stated. Its for manual tranys only though so if ya got a auto your stuck with the stage I.
Anyway I got a code for low cat effeciency. I also bought a Magnaflow cat while I was there along with header and downpipe and other stuff. As far as the other codes the only one I have that might be related to the kit is 2 manifold pressure codes. I'm not sure what they are so I gotta find out if its related.
As far as the belt issue my kit puts off alot of heat. and that keeps stretching my belts too much or wearing them out quickly. That may not be an issue on someone elses car but it is on mine. RSMs race car cavalier has the exact same system as I do and they say they don't have the issue I'm having. So I'll figure it out. Also alot of my belts that broke were do to not knowing how to tension the belt properly. Now that I know how to do it right it hasn't been as bad. My belts have lasted longer but I still had to change the last one recently do to it stretching too much.
The belts I'm using are gatorbacks. I did check with Goodyear to see if it might be the belts themselves. They told me that the belt being used for my kit is not designed to withstand that amount of heat, but that goodyear does make belts for nascar that would put up with the demand on heat and wear. Unfortunately they probably don't have a belt thats this small that they make. Also I drive my car really hard and I always put it to red line as much as I can. So my driving habits might have alot to do with the heat or not.
Don't let this dicourage you I love my system and I wouldn't give it up for the world. You'll never get the power out of a roots supercharger that you do out a centrifugal from votech. GM does not even have a setup for the ecotec and the ones for the 2.4 are worth only 40-50HP. I've got 95HP from this setup running it at 10lbs of boos.
Plus do you have a ecotec or a 2.4. that makes a world of diffence because the 2.4 runs off the main serpentine belt where as the ecotec runs of the intake cam. Two totally different set ups. So that makes a huge difference.

The 2.4 and the ecotec both run off the intake cam.Hey Blackvengeance, do you have any dyno sheets?

i just looked at rsms site today, its the first time that i saw it with the pictures. and the stage 2 did not say it had a head and t/b and it is 4900. it has bigger injectors and a bigger blower. their head is 950 and the t/b is 210. did you install it?

You want a lower compression ratio for a turbo/supercharger becuase the charger increases the pressure of the air being taken into the engine. This causes your compression ratio to rise so you want it to start out lower.

I just recieved my stage 1 in the mail. How loud is your BOV?
It's just now cutting it's teeth.
just had to bring this back im still interested
I talked to one of the RSM guys at the bash and asked him what kinds of time he was running on the 1/4 with the blue RSM car. It has a stage 1 kit on it. He said only 15 was the best it has run...? Can this be right? I should have asked him what the car is set up for probably.
I am interested the stage 2 kit but i would hope for more power than what he said their car was at.
Anyone run nitrous on top of their sc or turbos?
you have to think though most everyone was running a little slow cause of the weather at the bash some upto a second slower and some just a few .1's
the rsm race car is set up for road racing, far different than 1/4 mile dragging

I came a little late on this topic but honestly, if you want to get better cams, call up JBP and find a good grind to go with a boosted application. It wouldn't make sense to spend money on camshafts then have to get camgears to tune them when you can get camshafts for specifically what your doing and probably not have to waste your money on cam gears. That's what I think though...
