two questions about the rb25det

[67 411]

i was wondering how much one othe these weighs with or with out the trans? I also wanted to know what kind of power you could get out of it with stock internals, i have heard around 600 but that seems kind of high for a stock internals. anybody heard anything about this?

people make 450-500 hp all day and im sure some people have pushed their's further but i wouldn't recommend doing such a thing. There are problems that do arise but if someone is in those number's they normally know what there doing. Some thing's to look out for is the crank collar, people add the extended crank collar, the oil does not return to the sump fast enough at extended high rpm's so people either run a oil return line from the welsh plug in the head. I haven't used this method but what i am told you should use the top welsh plug to the sump, or run tomei oil orifices 1.5mm with the combination of the stock 2.0mm orifices in the oil gallery. The piston's ring's aren't that strong to withstand that kind of abuse. The rb25det is roughly 150 pounds heavier then the KA but a full tank of gas is just as heavy.

well if i could get 400whp i would be happy, do you know of any sites that show how to setup the tomi oil orifices, im new to the rb's so im trying to lern all i can, im reding through the faq thread now so maby ill find the answer there also.

so does anyone have anyone have any info i should know before i buy my rb25det? and what does it take to make 400-450hp i was thinking injectors fuel rail and intake and then turn up the boost, but would that be enough?

Post #3 is a good place to start, with what to upgrade and when it becomes a problem.
