MACHINE! Posted February 12, 2005 Share Posted February 12, 2005 Which bolt on turbo will i need to make a healthy250rwkw "BUT" with the most torque down low, i figure i should run the more boost like 1.1bar to make it rather than go external wich requires less psi but more lag. MY REASON: so on std boost my wife wont shit herself when it come on!!! any help boys would be a appreciated Link to comment https://www.sau.com.au/forums/topic/64410-rb25-wnt-250rwkw-wich-turbo/ Share on other sites More sharing options...
cameron Posted February 12, 2005 Share Posted February 12, 2005 HKS GT-RS turbo, 2530, 2535 & 2540 are good for around 250rwkw's. The GT-RS is claimed to of have the power of the 2540 and the response of the 2530. The next step up from them, still staying interal gate is HKS 2835ProS.

siksII Posted February 12, 2005 Share Posted February 12, 2005 i think he has a gtr, which means that gtrs's would be laggy and produce lots more than 250 when they do come on boost. if it is for a gtr, try gtss's 2530's or N1s, already they wont have much low down power(less than 4 grand) but go any bigger ie gtrs's and you wont have much power low down at all. best bet for stockish low end would be hiflo the stock turbos and run more boost.

SLY33 Posted February 12, 2005 Share Posted February 12, 2005 GTRS is your best bet, you'll never do it with a 2530. 2835proS will do it easily at only around 1bar, torque down low wont be quite as good as the GTRS, but you'll have plenty of scope for more power. You might say 250rwkw is more than enough right now, but when you get it, you'll want 260. Then 270. Then you'll be looking at cams and more boost for the magic 300!

ferni Posted February 12, 2005 Share Posted February 12, 2005 Stock fuel system isn't good for anymore than 250rwkw (unless you're from perth ) 2 mates with gtsts run 2535's and both make around 235 nonshootout mode... or 250-255 in shootout mode... very responsive and very quick.

lukits01 Posted February 13, 2005 Share Posted February 13, 2005 Stock fuel system isn't good for anymore than 250rwkw (unless you're from perth ) You think with Fuel pressure regulator and a good fuel pump the stock fuel system would be able to support 250rwKw? (and I'm from perth ehhehe :headspin: ) Im about to try a 2535 but dont have injectors at the moment, hope it'll get 250kw will have results by end of month Link to comment https://www.sau.com.au/forums/topic/64410-rb25-wnt-250rwkw-wich-turbo/#findComment-1207008 Share on other sites More sharing options...
paulr33 Posted February 13, 2005 Share Posted February 13, 2005 well yeah if its rb25 then check out a hks2540 theyre a good well known mismatched turbo and is extra laggy but will flow more than 2530 in top end or for around $2k get a gt30 with stock parts it should be laggy Link to comment https://www.sau.com.au/forums/topic/64410-rb25-wnt-250rwkw-wich-turbo/#findComment-1207062 Share on other sites More sharing options...

paulr33 Posted February 13, 2005 Share Posted February 13, 2005 but hang on a second, you said its for an rb25det, so do you mean a) skyline gts with rb25det conversion B) skyline gtst with stocker rb25det not that it really matters do you want a) a mid power turbo that will hit 250rwkw B) a mid/high power turbo with lots of lag and get 250 or a bit more cos you've said you dont want low down torque as your wife will shit herself yet your looking at 2530, t51z etc which will have fairly good low down response (not laggy) and wont flow much top end (not enough for 250rwkw), sounds completely opposite to what you want? if you want laggy and flow enough for 250rwkw then i still stick with hks 2540 (mismatched wheel/housing = laggy) gt30 (on stock internals will be midish laggy, not much before 4k) or speak to gcg in sydney and ask for a laggy turbo combination that will flow enough for 250rwkw on rb25det skyline maybe they can do a custom housing/wheel combo that it extra laggy for you and flow good for the same power level.

Jago Posted February 13, 2005 Share Posted February 13, 2005 Stock fuel system isn't good for anymore than 250rwkw (unless you're from perth ) lol response, i'd go for GT-RS, if you want something with more to offer later on down the track then the 2835 Link to comment https://www.sau.com.au/forums/topic/64410-rb25-wnt-250rwkw-wich-turbo/#findComment-1207252 Share on other sites More sharing options...

If I mis-read your post I apologise, but are you talking about hanging an aftermarket turbo off the side of a standard RB25DE. If this is the case I highly recommend against it, as to achieve that power you will need to lower the compression and change the internals. These turbos are fine on a std RB25DET but not on a std RB25DE.Within the month you will be looking at a total rebuild, if not a new block if it decides to "kick a leg out of bed".

MACHINE! Posted February 13, 2005 Author Share Posted February 13, 2005 Sorry boyz i meant GTST not gts. :headspin: i dont think 250 rwkw with response/torque is a contradiction at all its possible i just havnt found tha right combo yet but i will. Im not keen to push more than 250 so small bolt ons are perfect for me. trying to find trust trbos with t3 flange cant find any?? is there any?

paulr33 Posted February 13, 2005 Share Posted February 13, 2005 so you want 250rwkw thats laggy? well thats easy gt30 stock internals, aftermarket ecu youll be on the stock injector limit once it cranks past 4000rpm and hits its boost peak also will need to do the usual bolt on mods exhaust, cai intake, clutch, tyres, airflow meter (not 100% but will help) etc. things like cams, better tune, cai intake will decrease lag and u want more lag so dont do any of those Link to comment https://www.sau.com.au/forums/topic/64410-rb25-wnt-250rwkw-wich-turbo/#findComment-1207554 Share on other sites More sharing options...
paulr33 Posted February 13, 2005 Share Posted February 13, 2005 check out the rb25 turbo upgrade dyno post (search for it) and find the most laggy looking dyno graph. copy their mods and you shold be sweet. i suspect the hks2540 will be the most laggy or gt30 with stock internals, the gt30 is suited for a midly tweaked engine Link to comment https://www.sau.com.au/forums/topic/64410-rb25-wnt-250rwkw-wich-turbo/#findComment-1207561 Share on other sites More sharing options...
