in short, generally speaking you will fall just short (190 odd RWKW) from previous experience with a 25 turbo on a RB20, that is if you are using the stock 32 computer with no remap on a healthy RB20 etc. If it is remapped you should pull just a tad over the 200-210 mark but there are so many varibles so i cant give u an exact estimation.

High flowing the 25 turbo will pull the power you want, however you will also get reduced throttle response (read LAG) from this higher flowing turbo.

short answer is yes.

long answer is not if you want it to last a while.

people have run the RB25 turbo on an RB20 with remap and almost 14psi to get around the 190rwkw mark.

that sort of boost and more is just asking for eventual trouble.

that stock RB25 turbo can be hiflowed for about $2K (ball bearing centre) and be able to flow enough air to produce around 240rwkw... but you will be left with more lag up to around 4000rpm where things start to come alive.

okay so 4000 rpm is there any way of dropping those numbers to a healthy 3000rpm???

the reason this is being done is because the motor is in a e30 and there is about 20mm from turbo to the chassis rail GAY!!!

and from that info u have been told there isn't much help but you may be able to help with this???

i want 200kw atw and will basically do anything to get it just check out the myspace for pics www.myspace.com/iamjarryd

plz help me :rofl:

^^^ link ems (engine management system) is an aftermarket ecu. and i think he is talking about an R33.

just get a R33 stock turbo and put it on, run 13-14psi through it (wont be a problem on an RB20), get the car tuned and see what power output you get. if your worried about turbo clearance issues with the R33 turbo, dont. there is almost no external physical size differance in the two turbos (R32 and R33) its the internals of the R33 turbo that are bigger.

if you still dont get the power your after then get the turbo hiflowed. but i dont think you will see much change from 3500 to 4000rpm for full boost, even on a stock R33 turbo, which isn't that bad at all really.

should have gone SR20 dude..

with a stock S15 turbo bolted to it with usual mods it would have pulled 200rwkw and be less laggy than the RB20 with stock turbo

no 2 ways about it.

rb25 turbo "may" get you there depending on dyno.

a hiflow definitely will... but will increase lag.

yeah maybe but i also should have looked at dropping a supra enging in there to i know they fit but it was the money issue at the time

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

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
