I am getting my R32 back next week. I have had an RB25DET series 1 motor, and gearbox fitted. It also has a short shifter, Apexi AVC-R, heavy duty clutch, front mount, and full 3 inch exhaust with high flow cat.

Any ideas of what I can expect in terms of kw.

Boost levels are still not decided on for the AVC-R, going to have her properly tuned on a dyno, and go with the tuners suggestion.

Please keep in mind that this will be a daily driver - so boost will not be above 12psi..

If you can spend the coin then its the way to go. I havent been in dozens of modded cars, but i have been in a few, and my fav is a friends old R33/RB25 with a 2530. As a street car it was awesome, 230odd rwkws and the thing was mega responsive:thumbsup:

Im making almost that power with my RB20 but its just not the same:(

Ive got a series 1 R33 and have the same mods that you have listed.

My car just got dyno tuned and has put out 180rwkws but thats with a SAFC2 on 8.5 psi.

So if ya willing to up da boost a little more then i would say you would get bout 190rwkws and then you will be limited by your turbo coz they cant handle any more than 11 psi reliably anyway.

There was nothing wrong with the RB20. I just went in my friends RB25 R32 a few years ago, and was very impressed.

I bought the R32 very cheap to begin with, so I went for it. Just a big improvement over the RB20DET with sensible everyday driver mods.

GTST - no you can't steal the parts off it as the RB20 was sold today.

I will advise the cost when I get the final bill - hopefully it won't be a bank account tsunami.

I put a RB25DET series 2 motor, into my R32 12 months ago. At the time it was running stock boost, and achieved 155 rwkw (a good step up from 94rwkw).

You power figure will depend on how much boost you want to run. The thing that I love about the new engine, is the response of the series 2 turbo - I'm at 9psi boost by 2500rpm.

      EFR7670 exhaust selection RB26

      By LegendGTR · Posted

      I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀

      Stock Airbox and Snorkle for RWC - VIC west

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      Duncan's V37.......race car?

      By PranK · Posted

      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?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      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.
