    stage 1 upgrading to stage 2 ++

    i am looking to buy a riva stage 2 but for the money i think i will just get seperate parts such as
    - fizzle xs intercooler for half the price
    -r&d c4 or c5 monster charger wheel, spacer and housing
    -rear exhaust
    -15/20r impeller

    now do i need engine parts to make this kit work?, do i need injectors? rrfpr?

    its not clear and its hard to find the information but is this supercharger combo too lean?

    when i get to this level of boost does it get way too complicated and should i just get riva stage 2 to avoid the hassle. i dont mind getting my hands dirty but im looking to buy everything in one shot and the least downtime possible. the riva kit seems a bit expensive and it looks like i can get more performance and cheaper by mix and matching.

    basically im looking for a list of items that i need to make the supercharger combo work reliably.

    thanks in advance

    with either of those chargers and the IC kit ur gonna need to step up to a RRFPR to be safe and depending on water and air temps maybe even 42lbs injectors with it. I did the same thing u did when I started modding, went with X charger, and XS ic kit, 42lbs injectors and a rrfpr now i am up to the ET 140, but i do advise that u get a wideband to make sure ur not to lean, can always go with a riva stage 3 charger and the IC and just 42's thats a know and proven setup.

    I haven't seen anyone use the R&D charger spacers... I would go with a x charger instead with 42s and a rrfpr and an exhaust to get rid of the clutter where the intercooler goes. You should get a strainer though for the inşercooler and I'm not sure about what impeller you should use.

    I have been using the r&d C5 for a while now with great results. 11+ psi of boost @8100. I'm running the rrfpr with stock injectors and it works great. 80mph with my setup.

    Yeah the X charger is best bang for the buck if ur not looking for a big charger like the rude or Et's the C4 and C5 chargers are still stock size wheels with just bigger fins so yes 11 psi is nice but the X charger is a 137 size wheel and makes 10+ psi at 8100 with more volume then the C4 and C5 not bad deal at under 700 bucks for whole charger only 60 bucks more then the C5 kit.

    RXP with those mods should be doing at least 77+ easily
