looking to upgrade the turbo on my neo. has anyone used Kinugawa turbos? this turbo in the link has the closest specs to the HKS GTRS turbo with a slightly bigger turbine. there's two housing options AR-0.57(8cm) or AR-0.73(10cm), the GTRS has a 0.64 housing. would the 0.57 housing be too restrictive or would it be ok with the larger turbine?
dont know much about turbos, thanks.

GTRS:
compressor- 51.2 / 71.1...
turbine- 47.0 / 53.8
ex housing- 0.64

Kinugawa:
compressor- 52.5 / 68.0
turbine- 54.0 / 61.0
ex housing- 0.57 or 0.73

Hi mate, the kinugawa turbos are fairly decent quality, perform well and last a while. There is only one issue with them and that is internal gate models more often than not have boost control problems as the internal gate isn't really big enough on a td06 sized turbo. I had a td06sl2-20g on a sr20, i ported the int. gate and it was ok but still had some boost spike. After around 6 months of use and track work, the gate got all sticky and would jam up. I had to lubricate it and work it loose every couple of months. My advice to you after my experience would be to not buy one unless going external gate.

ok thanks, what exhaust housing better suits the rb25? ive heard the gtrs is a bit laggy and given that has a 0.64 housing, the 0.73 kinugawa would be even worse..??  are most rb25 guys running the 8cm housing?

      High temp brake fluid?

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣

      Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?

      Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
