Thought this might be a useful topic as so many people modding stock 25's are shooting for 300kw these days.

With this power level constantly in debate, lets get some stats...

use this formula:

mods:

fuel:

power:

oil:

useage:

lifespan:

I'll start the ball rolling:

engine 1 - R33 s1 RB25DET - 250,000km

mods: HKS GT2835 Pro S, 555cc injectors, fmic, custom CAI, atmo catchcan, other non related mods

fuel: bp ultimate / manildra e85

power: 280rwkw / 325rwkw

oil: motul 4100 turbolight 10w40

useage: daily /light trackwork

lifespan: 3 years

failure: spun bigend bearing

comments: motor also ran 185rwkw for about 5 years prior and was from a car that was tracked in japan as far as I can tell. motor had a very hard life.

engine 2 - Stagea 25 - modded for rwd - s2 RB25DET - 70,000km

mods: HKS GT2835 Pro S, 555cc injectors, fmic, custom CAI, atmo catchcan, other non related mods

fuel: bp ultimate / manildra e85

power: 290rwkw / 325rwkw

oil: castrol edge 10w60 (98 ron) / motul 6100 15w50 (E85)

useage: daily /light trackwork

lifespan: new motor - was stock power in an auto stag till now

failure: n/a

comments: New motor has a bigger sump (26 block) and is being run on heavier oil. Tuner is same and bolton's are same. So far it is more responsive, more powerful and everything is looking positive.

engine mods: Turbo conversion, GT3076r, Tial 44mm gate + screamer, Nismo 740 injectors, Power Fc + Comm,TurboSmart Bov, Exhaust cam gear, other support mods - read sig for rest

fuel: shell v-max (98)

power: 284rwkw 18psi / 21psi? 3xx?

oil: motul 8100 100% synthetic

useage: daily/cruises very light track work

lifespan: nearly 6 years (200,000km)

failure: standard servicing parts, of recent - water pump leak, internally, block has never been touched

comments: in my possession motor ran: 104rwkw - 1 year, 180rwkw - 1 year, 230rwkw - 2 years, 284rwkw - nearly 2 years so far

good idea Hamish!

mods: RB25DETneo, 6boost high mount, GT3540, Turbo smart 50mm wastegate & screamer Splitfire coilpacks, HKS fuel rail & 680cc injectors, front entry intake plenum, Power FC

power: 330rwkw @ 19psi, mid to high 200's @ 14psi

useage:occasional street driving, light track work

lifespan: been at least 3 years but would have been lucky to cover 2000km in that time

failure: none but the tyres don't like it, lol

comments: motor had 34,000kms when I got it 6 or so years ago, ran at 200rwkw on stock turbo until upgrade.

mods:s2 rb25det 140,000km, usual bolt ons z32 nismo 555 etc, nismo intank pump with 044 surge tank feed, hypergear tr43i turbo

fuel: caltex e85

power:307kw 17psi

oil:motul 4100 power

useage: track drift car

lifespan:2 years and still going

failure: not yet

comments: seems to be strong motor ran 2 years about 200kw, 1 year 270kw prior to this setup when was daily. Has survived a couple of track days with faulty CAS making it run lean at around mid 14s and no problems.

mods: gt3076 .82 IW, nismo 555s, 044 etc

fuel: bp98

power: at a guess 280-300rwkw

oil: usually hpr5

useage: almost every weekend with a couple of failed trackdays

lifespan: 2 yrs at over 250rwkw

failure: n/a, pulled it out to go 30det

comments:Motor never made as much power as others seamed to but never let me down, copped up to 25psi and a lot of knock along the way as i was learning to tune it myself. copped a fair bit of limiter abuse, oil pump is still going fine now on the 30. also ran for a week with a dud fuel reg and was leaning out to 15:1 under full load. when pulled down the pistons had very slight det damage but bottom end is otherwise perfect and will probably be used again when i eventually sell it.

mods: R33 Series 2 RB25DET, Internally gated .82a/r GT3076R, Splitfire coilpacks, Nismo 555cc Injectors, Walbro 500hp fuel pump, GTS Link ECU, 600x300x76 generic intercooler, Trust PEII Exhaust, custom dump pipe and intake/intercooler piping, 4" K&N pod filter.

fuel: Mobil Synergy 8000 (E10) and BP Ultimate at different times

power: 270kw in 2006-2009, 301kw @ hubs at 17-18psi highest in early 2009, ranged from 284rwkw (lowest reading after raising boost to 17psi, on a rolling road dyno similar to DD) up to that highest figure depending on dyno, boost and day

useage: Occasional street driving, light track work and some drags

lifespan: Installed GT3076R and first tune for 270kw at ~100,000km in 2006

failure: No failure - stripped big turbo etc from motor just before 200,000km as I felt like time for a change and had someone keen to buy my old turbo, injectors etc in mid 2011. Motor is still running fine with a stock turbo back on it.

comments: Motor had 61,000kms when I got it 8 or so years ago, ran at 200rwkw on stock turbo until upgrade at 100,000km.

mods: R33 Series 2 RB25DET, Internally gated .82a/r GT3076R @ 17/18psi, Splitfire coilpacks, Nismo 555cc Injectors, Walbro 500hp fuel pump, Link G4 GTS/GTR ECU, Blitz LM FMIC, HKS Hi-Power Silent Exhaust, custom downpipe, 4inch intake, Simota 4inch pod

fuel: Mobil Synergy 8000

power: 285rwkw on a dyno with a dodgy wideband. Maxxed out the injectors. Retuned to more sensible Duty's and felt quite a healthy increase of butt dyno power, yet to re-dyno so will update soon.

useage: daily driven, and driven relatively hard. and regularly tracked

oil: Royal Purple 10w40 with royal purple oil filters and Mocal 13row oil cooler.

lifespan: Still going strong. No oil usage or dodgy sounds.

failure: squeaky brakes

comments: bought @ 47,000km stock, modded to 200rkw, tracked hard. Installed GT30 @ 80,000km, (87,000km now) still tracked hard.

I guess its a good indication to Garrett's turbos too. Over 100,000km on two cars that arent driven like nanas ever.

Poke poke poke....

I want this thread to thrive! I want to get the Stag to 300kwatw, so this thread delivers.

I'm really only lacking turbo and injectors but don't know whether to go the 3071 (unlikely but would love the response) 3076 (likely) or HG G3 or SS2? (i think?[quite possible]).

I'm forever switching and changing so I'll be watching this thread with interest.

Interest! Interest! Yep watching this with interest, the only thing stopping me from the Kando is I have to go external gate - all the hassles of plumbing and I already got my neww JJR front/dump fitted, which will need to have the dump modified if I do go Kando... And 'jet something' mentioned a link (in another Garret turbo thread) from the US where u can get the GT3076R delivered for $1300...A superior product cheaper than a Hypergear..?? Good to go

    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
