95silvia Posted October 7, 2003 Share Posted October 7, 2003 First of all, Hello. Im new to your fourm. I have been swaping sr20dets in to the US spec 240sx for 5 years and about a year ago I got 2 rb25de motors really cheap... so now i want to put one in an s14 I bought on Ebay but I think i will need to go turbo to make 350hp... (sorry I dont know kW) anyway do you think it can be done with out changing to lower comp. pistons? say I just bolt up a stock rb25det manifold and turbo... i have the r33 rb25 wiring harness and mafs ... i still need an ECU tho... and i used left over sr20 370cc injectors. I would kind of like to get it running with the det ecu, mafs, and inj. then add the turbo. so what do you think ? will it work or am out of luck? oh here are some pictures of my sr s14: http://www.entuning.com/jex.html and pictures of the s14 that will be getting the rb25: http://www.entuning.com/black240.html and sence im introducing myself here I am at a show last year:Christopher Jex Dallas Texas Link to comment https://www.sau.com.au/forums/topic/26460-rb25de-rb25de-t-introduction/ Share on other sites More sharing options...
Nismodified Posted October 8, 2003 Share Posted October 8, 2003 i think it would work. The question is of reliability of course. If you stick to using low boost levels, 5-7psi, then you could get away without lowering the compression. I hope you were talking about using a stock RB25T ecu, because i dont think the Non turbo ecu is up for the task.

95silvia Posted October 8, 2003 Author Share Posted October 8, 2003 yes, Nismodified i ment to say that it would be with all rb25det electronics. which I am still looking for the r33 det ecu so if anyone has one let me know. thanx Cjex Link to comment https://www.sau.com.au/forums/topic/26460-rb25de-rb25de-t-introduction/#findComment-561145 Share on other sites More sharing options...
streamer Posted October 11, 2003 Share Posted October 11, 2003 ive heard u need more than that. stuff like an o2 sensor and etc. Go to the FOrced INduction performance section or do a search for my thread, "parts needed to turbocharge" and it might be of some help laters Link to comment https://www.sau.com.au/forums/topic/26460-rb25de-rb25de-t-introduction/#findComment-564929 Share on other sites More sharing options...

95silvia Posted October 13, 2003 Author Share Posted October 13, 2003 I found a few more things about a rb25de to rb25det swap .... the AAC and idle air motor and there are no piston coolers on the NA rb25 here is the link: http://village.infoweb.ne.jp/~naninani/ser...rvice/rb25.html Link to comment https://www.sau.com.au/forums/topic/26460-rb25de-rb25de-t-introduction/#findComment-567742 Share on other sites More sharing options...
streamer Posted October 19, 2003 Share Posted October 19, 2003 no piston coolers but is there any modifications we can make to it to make sure the pistons dont overheat etc? my mechanic quoted me arnd 8k yesterday for a full job.. forged internals, conrods, gt30 turbo and etc etc...expects arnd 300 at the rw.. or with forged internals, i dont need the piston coolers?

95silvia Posted October 19, 2003 Author Share Posted October 19, 2003 Well im sure they (Nissan) didnt just do extra work and spend extra money out of the goodness of their hearts... there is a sound engineering reason for them. that said I think if one is cairfull you can run a turbo on anything and be safe just so long as you do it smart... ie: big intercooler, oil cooler, bigger radiator, maybe even water injection. I know the FWD sr20de's here in the states came with out the oil squirters and jim wolf tech. puts them in fairly regularly. I'm planning to run my rb25de-T whith out them, but I'm also planning to run low boost 5-8 psi. I think you wil be ok making 300hp with out them ... i think 350 will be ok. if i can ever find an ECU I will report back annd tell form experiance what works and what does not.

streamer Posted October 20, 2003 Share Posted October 20, 2003 Cjex, if im not mistaken, my mechanic is planning to use the apexi power fc which is readily avail. in the US or the slightly better australian made Wolf EMS.
