First up jus sayin hi, ive been a long time reader of SAU and coz i own a S13 I'm mostly on NS but coz of this post i thought i better enlist the help of the ppl that know the RB Best
(Modded Post from NS)
Jus after some help atm, Ive currently got a s13 with a SR20DE and because Im on the new QLD P-Plate laws I cant have a turbo /cry.. Anyways Ive been thinking y don't I go RB30DE, now i know that it would be a big piss around having to get a rb30 bottom end then get a rb25/26 head and work out all the other things aswell but if done rite would it be half decent in a s13 ? and as im looking at getting drift lessons/start practice days later the year it would be nice to have more then a pretty stock standard sr20de (before i start i will have all the handling things sorted out so jus need power..), so yeah jus looking for some info on the following things:
1: Most important thing i guess is the legality's: I assume if i get ALL the work done at a decent shop with mod plates and all, QLD Transport should be ok with that coz im under the impression that u can only do "big" mods if they are engineered and (possibly checked overy by Transport to make sure they r ok ?), because afterall y bother to go to all this trouble to make a NA that i can drive if i will jus get fisted anyways.
2: Costs / Whats needed: Done a bit of browsing on SAU and some other sites about the RB30DE build and so far most ppl say that u can pick up a rb30 for under 1k easy and then spend maybee upto 1-2k for a half decent rb25/26 head. So say bout 3k max for the bare engine ?. Now obviously coz im gonna be putting this into a S13 I will need gearbox + other tranny stuff and im not sure if I would use a rb25 box or watever ? and other running gear to get it working so say maybee another 2k for that ?. So far that is about 5k (Am I overestimating/underestimating ?) then to find a place to take my old sr out and put in the rb and get it all running would prob cost me a bit aswell. By rough estimates it would prob cost between 5-7 k to get it sorted ?
3: Would it work: From looking on NS and SAU and quick google i havent really found anthing about a RB30DE into a s13 and i dont think its a very common build. Ive never even herd of a rb30de sil before.. so if there is anyone out there that has done it, wat is it like and was it worth it ?.
4: Figures: From info off SAU most ppl that have done this that normally use a skyline or cefiro and figures ranged from wat mods they had but generally ppl were sayin anywhere between 120-170rwkw's depending on mods, wat do u think ?.
Lastly I know that most ppl will say im a loser for even considering this because i will be off my p's in 3 years and be able to drive a turbo then but i havnt got this set in stone or anythign yet im jus looking for info atm and wondering if it would be a benificial and viable build. Will prob add most questions as they come to me lol.
*EDIT* - Also forgot to add how much power difference do u think i would notice if i did it rite would there be from the my current SR20DE ? (sr is out of a s14 so spose i could get the vct running to make it better then normal sr20de if i got s14 ecu but i would be getting vct if i got a 25/26 head on the rb anyways..)
