Will a RB25 turbo bolt on to the standard RB20 housing?

will the bolts and so on line up?

Will there be any need for ECU changes?

when you say boost comes on earlier, which one are you talking about?

Im running stock turbo..

And have dyno proven at least 260rwhp.... had to cancel run because fuel pump was leaning out ...

Friend of mine (GTT 25) on these forums mad 240 hp @ only 11psi.

From my experience there a bit more in them than that.

Meg's,

The dyno that Bark's (ethan_R33) car made 177rwkw on has also been used to dyno Freebaggin's GTS25t. Freebaggin's car made a tad over 200rwkw on the stock turbo (FMIC, exhaust, Microtech etc...) FB's Microtech was tweaked again (later on) due to pinging issues (i think?) This resulted in mid 190's. This is the same dyno my car has made its last few rwkw figures on.

Ethan_R33's car made 149rwkw before the S-AFC was tuned, & 177rwkw after it was tuned (the timing was advanced too).

A totally standard GTS25t makes ~128rwkw on the dyno in question (from the owners mouth).

Matt.

Jim I thought your car was a sh1t hot stinker when you got it.

I could be wrong ,

a good up grade is ethier a t3/4, t4, gt25 series, hks 2835 hks 3040,td06,td07n apex ax 6 (I think its called) and a t88 and yes they do fit. and about a dozen moreIt all depends on what you want.

    • Thanks for the reply, So i've continued playing around, and fitted the injector adaptors onto the injector, the fuel rail is not able to be mounted now as the injectors sit a bit further out. I suppose the point of the adaptors is so that the injector nozzle isn't so deep into the intake? I suppose 1mm extra on the o-ring would do it but still can't mount the rail onto the intake haha. Waiting on a reply from Aeroflow I'm sure there's something stupid that I'm missing...
    • I have a radium fuel rail on my Greddy manifold and used the supplied radium fuel injector to manifold adapters (The round green things pictured). I did always wonder if you could just go ahead and use the second lower hole like you're doing... Wouldn't thicker o-rings solve your issue?    
    • From what I've seen and experienced first hand with those powder extinguishers, they're good to use to break a window and escape the car, and half the time then do f**k all to stop a fire. You just need much more than 1KG worth of powder. Not to mention, half the time it's an engine bay fire, and you can't easily, and do not want to completely open the bonnet, so you're left pretending to be an American Infantry... Spray and Pray baby!   And then 100% that shit is really destructive afterwards!   Realistically, those little ones at a race track might help you keep the fire from growing and give the fire marshal / truck a chance to actually get to you with their multiple large bottles.   For a road car, these days, prepare to deboard as quickly as humanly possible, and move to safety. Allow insurance to fix replace it (unless it's like a rare classic etc, then do nearly everything possible to save it!) Keep the little extinguisher with you to help protect other things around you from burning while you stand there singing "How can we sleep while our beds are burning?"   Secondly, powder extinguishers I freaking hate for indoor use, (this isn't really relevant to a car) as you will get a powder fog around you, and it can be disorientating.   When I did fire training when at BlueScope Steel, they have (had?) their own fire brigade on site. We did all the training, and at the end we were told, "If it's an indoor fire, and you need to use a powder extinguisher, we as the fire brigade would rather you just exit the building, you're more likely to get lost in the smoke and powder fog than do much help, so just GTFO" And pretty much that was what they said for most other fires too, grab extinguisher, if it's much more than paper in a bin fire, use extinguisher to get you and others out of the building to safety...   Part of me wishes when my Skyline caught alight many moons ago, I let insurance sort it out, instead of putting the fire out... part of me now says "But I've saved a classic before it was a classic!"
    • Hi all,  I have a older model of the Greddy Front facing intake on an RB25DET NEO Head. I've bought aeroflows fuel rail and injector kit (1000cc Bosche injectors) and I'm unsure if the fitment is correct. The injector o-rings fit in the intake hole but it's not snug. I can very easily rotate the injectors even when the fuel rail is mounted. The kit also came with multiple adaptors, they dont make it any more snug and using them raises the injectors up and i cant mount the fuel rail. I hope this makes sense I've asses a few photos.    Thanks so much guys.
