its not a garret? i thought it was...

its compressor wheel is steel, while its exhaust wheel is ceramic, just like the rb20 turbo. this means that at high boost it can generate too much exhaust heat and the exhaust wheels can delaminate and separate from the shaft. That's why people say generally they have a maximum boost that should be run through them without damaging the turbo...

on an rb25 engine, its good for 11-12psi max

on an rb20 engine, its good for 14-15psi max

its a great little upgrade on the rb20 motor as it provides more high rpm pull without getting too much lag down low

PS welcome to SAU :rolleyes:

eh ur turbo kicks in at 3500rpm? my HKS GT2840 is boosting from about 2000rpm why so high?

because if you read the first post yo would see he has the rb25 turbo on a rb20. rb20's don't spool as early as 25's.

and yes they are really ball bearing. it is slide's highflowed ones that aren't. the only difference is the spool up time. once they are up and going they perform just like a ball bearing.

      Another "where do these lines and plugs go" RB25DET question

      By thatjawncrazy · Posted

      GTSboy, thank you again. i’ve been reading all the other SAU RB25 vacuum line threads and you have the utmost patience for people asking “where do my vacuum lines go”. it’s appreciated. i did also enlist a few other RB guys local to me.  i would like to run 5 to 4. turbo pressure side to wastegate actuator. i would like to run 3 to 1. power steering air valve line to intercooler outlet. (this is how it was previously). i was told 2 is the bleed port for the boost solenoid - which i’m not running - so should be capped.   anyone see any problems with that?

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.

      Blue slip

      By Stringycheese · Posted

      Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?

      Blue slip

      By PranK · Posted

      I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.
