Guide: RB25 Swap Wiring

[89Baysideblue]

i may be wrong on this but...i dont know of any chip for the series II ecu. it is a smarter ecu then the rb20 unit. for the rb20 i know it is easy to modify to get whatever gains, but with the r33 ecu it is more dificult to modify.

haha yeah your right it hasn't been done but i know i guy thats currently trying it on his r33 and i'm in line for one of the first prototypes hehe

i also heard the CAS on both the series 1 and 2 are wired differently than the rb20 do you have any idea what the pinouts are on them? Google is not cooperating on that.

www.skylineowners.com is your friend when it comes to this tech crap!!

check them out, theres a manual for the r32/r33/r34
but i believe its in the FAQ forum

Hey I have just read this whole discussion as well as others on swapping an rb25 in an r32. However I am getting confused with all the mixed info or I am just not understanding it. Long story short I have an r32 GTS-T that I just pulled the rb30det from, I have an rb25det series 2 with the ECU and full harness. Now from looking at different threads and looking at wiring diagrams I beleive I have 2 ways to do this but PLEASE correct me if you are wrong or have done this already.
1) RB25det series 2 engine and ECU with rb20 harness, modifying the injector harness and using the rb20 igniter and coils
or
2) rb25det series 2 engine-ecu and harness complete

let me know if this is wrong, I thought I was on the right path but looking at other convo's I got very confused as well as there doesn't seem to be much info on the series 2, the only reason I got a series 2 is because I got a good deal anyway but I was under the impression I could just swap the igniter and coil packs from the rb20 and I can make it work

Thanks for the any info, and like I said, i did do research but I keep finding conflicting answers

bump, any info would be appreciated
