kidafa Posted November 7, 2009 Share Posted November 7, 2009 Don't do half that crap listed above. I can not believe someone wasted their time typing all that out. Well lets see your opinion on what to do then No including 26 conversion and a 34gtr front end cos not all of us have mega coin to blow! Does look like the hottest stag in aus imo though mate I'd be doing: 3" turbo back Split Fires (if yours are missing AT ALL) FMIC EBC hi at 12 psi Pod in a box with cold air feed and $5 intake pipe mod SAFCII and SITC or as you have a S2 get the chip put on the board Link to comment https://www.sau.com.au/forums/topic/295241-rb25det-neo-modding/#findComment-4923858 Share on other sites More sharing options...
QWK32 Posted November 7, 2009 Share Posted November 7, 2009 (edited) Darrin is still running the RB25 Neo. To see 250rwkw and just above can be done on an unopened engine. basically what i will be running is: - FMIC - Ecu - Fuel pump, not because the old one is dying but just for piece of mind - Injectors - Turbo upgrade, stock turbo would see 200 but not much more. - Full 3" exhaust - Air Filter with CAI running a safe tune and boost level i hope to see between 220rwkw and 250rwkw. total cost for me, around the 5k mark.

Assuming that your exhaust is 3in the main ingredient is a big turbo such as GT 3076 (or even a GCG highflow) and you should get over 240awkw. You could save money by getting a nistune instead of the PFC and spending the money on the turbo! (Oh and get a boost controller instead of the radiator).

Sounds literally exactly the same as a Neo engine I know My advice though, get the GTRS instead.

RBfreak69 Posted March 13, 2014 Share Posted March 13, 2014 Hi guys, Ive got a 99 Stagea RS Four S and im wanting to start building up an engine, ive found a 25det neo with 89,000kms for $2000. Just wondering what aftermarket parts i should get, nothing too expensive. Cheers Link to comment https://www.sau.com.au/forums/topic/295241-rb25det-neo-modding/#findComment-7227225 Share on other sites More sharing options...
Ben C34 Posted March 14, 2014 Share Posted March 14, 2014 That question is so pointless and not answerable if you don't specify a budget and what you want. Why build an engine anyway? Unopened engines are good for well over 350kw. Link to comment https://www.sau.com.au/forums/topic/295241-rb25det-neo-modding/#findComment-7227239 Share on other sites More sharing options...
RBfreak69 Posted March 14, 2014 Share Posted March 14, 2014 (edited) I don't want to spend heaps, Don't really know what my budget is yet. just looking around 260kw mark atm. I wasnt meaning opening it up. Just external stuff Edited March 14, 2014 by RBfreak69 Link to comment https://www.sau.com.au/forums/topic/295241-rb25det-neo-modding/#findComment-7227254 Share on other sites More sharing options...
wolverine Posted March 14, 2014 Share Posted March 14, 2014 FMIC, bigger injectors (480cc),new fuel pump, bigger turbo (hiflow), engine management (Nistune), 3" turbo back exhaust would be the most basic modifications required. You can choose, bigger and better items but that is a basic starting point. 1 Link to comment https://www.sau.com.au/forums/topic/295241-rb25det-neo-modding/#findComment-7227493 Share on other sites More sharing options...
