I know this question has been asked a million times but how much power (HP OR KW) can the RB25DET take before you need to change internals. I got an R33 Series 2 and thinking of upgrading turbo, any recommendation on a turbo which produces abit more power than factory but i don't want to change internal.

What is the best turbo to use to prevent internals to be changed?

How much can a rb25det take?

cheers

John

DO A SEARCH, this has been covered so many times its not funny!!

300rwkw is a nice safe limit for stock internals provided it has been tuned by someone that knows what they are doing, also the conditon of the motor and the quality/type of parts that are being used will determine how much power if will make reliably.

270rwkw is a safer limit if you want it to last. although depending on the engine condition you could probably push 300rwkw but at this level the stock internal engine will let go eventually.

my mates 33gtst was running 19psi with a high flow garret he drove it every day for like 2 years(who knows how long with previous owner) then a piston finaly cracked so i'd say if not running more than 16 psi should handle pretty well.

      R32 only blows hot air

      By Duncan · Posted

      Not really, but the heater box is pretty simple mechanically....if the door is one way the air bypasses the heater core and if it is the other way it goes through it for warm air.  If you are sure the actuator you moved manually is for the heater mix (there would also be one for output air direction) then I'd take the heater box out and see what is happening (you'll have to regass and re-coolant the systems afterwards) BTW pp724 onwards from the GTR workshop manual cover the system in good detail, it is probably worth checking. I think the IAT sensor might be a problem electrically for getting cold (if you got 24 error code not -24 it thinks the incoming air is -50c) and it covers how to test the sensor (although most likely it is either not plugged in or a wire is damaged)

      Use the GKTech subframe bush and bring your subframe 10mm closer to the chassis. You'll need to fix an exhaust hanger to suit. One of the best mods I've done.

      Wires cut underneath shifter cover

      You'd really have to pull it apart further to know, it least you can be confident that the one heading to the back is not connected any more. There was once a ground on the shifter seal mount too, your head unit issue could be that simple

      Perfect, I'll get to it this winter then at the same time as I weld on my anti squat kit.

      R32 only blows hot air

      By SeanR32GtSt · Posted

      Alright so my 32 only has one temperature no matter what degree you set it to. I’ve tried disconnecting the servo motor arm and moving it either direction and got no change. I’ve fixed the leak in my AC and re charged it and with it on and clutch engaged it still blows hot even though the low pressure pipe going to the firewall is ice cold. Both heater core hoses are hot while running as well. Diagnostic code showed 24 for intake air temperature sensor. Anybody got any ideas?
