is it possible to sub out the rotomaster turbo for say a precision line turbo you carry and not have to pay full price for the stock rotomaster turbo still? meaning the price of the stock turbo is subtracted from the precision, or something like that could be worked out?.
Also when's the rotomaster spool up and start making boost on the 12v vr6 and what rpm does it hit full boost? I'm looking for something in the range of high 3's to high 4's, or 4-5k range. Was looking at your billet hp series because someone told me the sport compact's arent available anymore?
any recomendations you could help me with reguarding the info I stated above, also journal bearing, can't afford a chra bb

. are they all watercooled and oil cooled or are there any options for just oilcooling?
thanks
edit, forgot to mention my objective's a fun street car, wont see any track days so huge a/r's are needed, but I also don't want it spooling under normal everyday low rpm driving, boosting 24/7.
