Nismo RS580 N1 turbos?

[MidnightGTR]

Can anyone shed some light on these turbos for me? ive tried a few search on google but the best I could find were some Jap websites with the specs but not much else info.

The serial number is 14411-RS580, which doesnt match up with any of the 32/33/34 series N1's so im thinking they may not be an "official" N1 turbo, yet judging from the specs are pretty similar.

The Nismo Lemans turbos have the serial number 14411-RS581 so im guessing these are somewhere between some sort of N1 spec and lemans specs?

What about effecient boost levels? ill be looking at running around 1.2/1.3bar so I hope they will be ok at these levels

If anyone could shed some light on what the spoolup/response/topend power is like or anything else about them id grately appreciate it

hi mate from memory when doing research the rs580 type are off the 400R. so yer are very rare but yer not 100% sure if i'm correct just going off my bad memory yes 1.2-1.3 bar won't a problem what so ever. 1.5bar is about max they can handle efficiently wise. the spool up, top end power will be basiclly the same as the r32 n1 06uoo's any ways hoped that helped

Not to sure where they really belong, but all I know is that they are rated at 300ps each and should be able to handle 1.3-1.4 bar. They are also very similar to the R32 N1 turbos.

Here are the pics.

so would they be any good on a standard rb26 then?

I want pretty good response with these turbos rather than topend
