questions about the rb25det

[sL103]

hi guys well this is my first post ever on this site so dont flame me too bad i just had some questions on the rb25det if i do decided to get a 240sx (s13) fast back. i did own a 300ZX NA 2+2 and have worked on many Zs. but well since i dont think im going to be able to get another Z anytime Z im probably looking into getting an s13 but this all depends on which engine i want to put in. so alot of people do the ca18det and the sr20det of course and some turbo the ka24de and then some even do the rb20det. since the rb25det is a r33skyline engine thats for surely a plus, also its a good gain swap. but here is what i would like to know.

t or f ??? i can use the stock s13 subframe or use the r33 subframe??

t or f??? better to get the engine (complete) or a full front clip??

rough price ranges would be nice ive seen 3-4k ( sounds about the same for a TT engine

whats the accessability of aftermarket parts for the engine as well as stock parts???

what turbos are nice for the engine?? sounds like a td05 or td06 would be very nice gain

well hope that wasnt too much to ask and i would apperciate all the advice i can get before i do anymore research

but i know the swap is possible and to me would be a very nice gain from stock of course ;-) and something different that the sr20s and ca18s out there but i know some people around here who have done those swaps and they very sweet too ;-)
