RP turbos are terrible. Borg warner are nice. Enough said.
buy ck04's from ebay 500$ tops - then buy new chra's from BAE 590$ and you have 99% equivalent reliability to BW k04 - you will need to port the exhaust manifold wastegate and adjust the lifter arms though.
if you arnt handy, then just buy frankenturbo or BW
Don't even bother wasting your labor hours money on cheap chinese turbos. You'll save more money in the long run from buying proven quality turbos. If you do go with the cheap turbos, I'd be curious to see how well they function and last. IMO, you should Save up till you got enough to get good ones man.
im speaking from experience just an fyi we don't all have the ability / self control to save up that much for our cars, im just giving him a VIABLE cheap optionQuote:

I modified mine right away to fix http://www.audizine.com/forum/showth...oost-Creep-FTL
Ported the exhaust wastegate holes and adjusted the lifter arm lengths so that they would open like the OEM one does
Replaced the chra's with new ones built and balanced by BAE - so far so good, no whistle, no problems,
Total was 1100$
i have a set of blown k04s in the classifieds. just rebuild and you're good to go...
You could go this route, would save you modifying the wastegate side of things so 1000 + 590 and you have a set of solid like new k04's = 1590$Quote:

Or you buy brand new = 2500$ @ ecs or something similar
DO NOT BUY RP - its the same shit as the china k04's from ebay with shitter than shit chra's
Never ever get RP K04's for our cars. After running them on my old silver sedan, I'd sum them up by saying the following: I would have been better off installing blown Borg Warner K04's than installing those RP pieces of shit.
All these RP threads! I wonder how many people buy these things without doing any research.
something like this thread should get stickied
