Coming over from a turbo DSM, I want to try S/C.
My custom user title says it all. I was deciding between an s52 swap or a kit and I said screw it, sunk cost on the motor already so ill do both.
I'm in my build stage where I want to pick my poison :evil2 My options
FIRST - Stage 1 RMS Vortech V2SQ. This kit is new and is only missing a tune. Catch is, it's from 2005 and has been sitting in original packaging since. I know RMS has a bad rep, but their tune isnt being used anyway and I really won't be dealing with them I guess since I called RMS and asked, they took my number and said they'd have a tech call, but no one got back to me. I also read they've shipped out kits that were missing alot of parts...is there a PDF for install anywhere I can run though this guys first to make sure? The seller is willing to meet me in person on the way during his 10 hour trip for parts so I could check all this in person before I buy.
SECOND - AA kit with ROTREX C30-94 that has been used except the blower has been replaced with a new unit 3K miles ago. This kit is missing a tune and injectors, but includes an intercooler and oil cooler. Seller is reputable for shipping and going turbo which is why he removed it. This kit is 200 dollars more.
THIRD - DINAN Stage 1 V2 Vortec . This kit has 40K miles on it and has been installed and randomly tracked since 2004. I spoke to the owner and he knows what he's talking about. It's 100% complete, but also 900 dollars more than the rotrex and 1100 more than the RMS kit.
From my reading experience (love night shift) I've learned
Vortec is better for bigger power later in RPM band and in upgrading boost, but the low end kick isnt as potent as the rotrex which is pretty maxed out at about 10PSI. Vortech is rebuildable and will need it at smaller intervals, but still nothing too bad. vortech is larger making an intercooler set up alittle tougher to overcome. Also Ive heard they can't be run under 25 degrees and then Ive heard this is BS???
Rotrex are smaller units and should see 100K+ before they die IF properly maintained. They cannot be rebuilt even if superchargerrebuilds says they can. This will kick lower, but isnt really upgradeable for more power later.
I have an S52 in my basement that I am going to CES HG and ARP stud, but that will be later. My S50 is running excellent at the moment with only 95K, so I will likely install and use this now while I work on the S52.
Power desires aside, which blower can I assume more reliable for daily use? All temps, safe AFR's, safe boost. Basicaly they kit and tune will be written to be overengineered so as to maintain streetability and health of my motors.
