btw.. I made 164rwkw which is 221hp on 1 bar of boost.

Its not just about peak power its the mid range that gets you there so the RB25DET will be quicker in accelerating to the peak power.

Considering though the RB20DET does do extremly extremly well in the power department. Especially considering the RB25DET has VCT, bigger turbo, higher static comp ratio etc..

Just to throw some spice into the conversation, my CA18DET did 214rwhp fully tuned with an SAFC etc, and my RB20DE does 120rwhp with no tuning, no oilchange running 95RON fuel :)

its not about displacement sometimes...

Snoop, are you doing the conversion yourself? If you are then i'd honestly put about $2500 aside for things such as timing belt, fuel pump, filter, oil, sparkies etc. Second of all, you will need to do something about the sump hitting on the sway bar and the clearance of the engine ie hitting the roof. Are you good with wiring? If not then put aside about 300 at least for getting someone to do the wiring and adjusting. If you already have a sr20det then stick with it. I promise you you'll be better off.

The front cover turned out to be stock aswell, I originally thought it was a VG30 item but that would mean it would be smaller than the RB25.

The turbo is still running fine after two and a half years( with a greddy cooler which I think increases its life)

I am having it rebuilt because a friend of mine was helping me pull it to bits and snapped my turbine off the shaft with a badly aimed hammer....=(

Rebuild specs b4 u ask are

compressor- T04B V trim

top 52mm

major 72mm

VG30 .7 A/R exhaust housing and turbine

    • If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.
    • Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)  
    • Murphy strikes again! Nothing at all would have gone wrong if you had the tool kit in the car! You'd have just found the clamp loose the next time you went to touch it...
    • I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...
    • Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
