engine upgrades (silvia/skyline)

[slix]

okay ive decided to purchase a 98 240sx and convert it to a silvia (at least the body)

assuming that price is not a major factor, in order to produce max speed/power, without sacrificing handling, what would be the better engine to put in it?

the standard s13 silvias redtop sr20det or an rb25det from a skyline?
also do any of you know of a site that sell turbo kits for either?
if i were 2 choose the rb25det, would i have 2 get rid of the single turbo already on it?
Also if any of you know how much hp possible with any of these setups or prices to get this done, please help me out.

the S13 SR20DET is alot weaker engine then the RB25. we're talking 200hp vs 250hp. the RB doesn't weigh much more, and can handle as much if not more power. the only 2 cons about it are a) it's more expensive and b) parts are not as easily available in North America. if you have the money, go RB25. another option if you don't have enough for the RB25 is the RB20 or the S14 SR20, both of which boast more power then the S13 SR and are both cheaper then an RB25.

thx a lot. btw, do u know anything about transmission upgrades that need 2 be made?

you need the RB25 transmission with the engine. it won't work with the stock 240SX transmission.
