Bruno, when I read that, it cracked me up so hard. They're usually rusty, because the exhaust housings are not stainless steel :)

I know you're joking though.

Generally, on the forums here, expect to pay about 350-400 for a sI turbo.

400-500 for a sII turbo.

Don't get sucked in like some guys where they try and buy a cheap one. if someone's selling it off for cheap, it's usually for a reason - namely that it's old or worn.

Sometimes, you can get unlucky, like i've bought a turbo, and shaft play was good etc, but it popped almost as soon as I put it on. But generally, the ones in better condition will last.

If someone has taken the turbo off a low k car, and is looking for $50 more, $50 isn't that muich in the scheme of things. I would take his over the one that is selling for $300.

What is the reason for the rb25 exhaust elbow not working? I ask because I have a late model RB20 in a us spec 200sx (240sx) and I put a rb25 neo turbo on and I don't recall reusing the rb20 elbow. Everything was a straight forward swap for me.

I think you mean the compressor outlet elbow, RB20 one has slightly smaller casting than RB25, you can make it fit by slotting the 3 bolt holes and porting the ID of the RB20 one, works OK.

hey kids.

just lettin ya know that i checked my water line banjo size today and yep they appear to be the 24's

so my 1990 has 24's

so it really from my research and what i heard it looks like it was early 89's that had the 22's which will cause some prob. that's how it appears anyway.

hey gt-t r34 so you had to make up a new gasket then to go between turbo compressor and elbow???

cos i may be in this situation cos lookin at buying an r33 trubo but without the gasket betwwn the compressor outlet and elbow.

so what did you use??

i'm thinkin of just goin to repco or somethin and seein if they got some metal gasket material. would this work??

i tried to hack the shit out of the standard one but no luck couldnt get it big enough, so i used coppermaxx which you use for you exhuast and stuff its like silicon. good luck its pretty easy to change them over just take your time.. and look at preditors guide(www.project32.net) great DIY

I changed mine about 2 months ago - 1990 GTS-t -> Series 2 R33 turbo. I had the 24mm banjos and I also used the R33 compressor outlet elbow. Sort of on the same topic, where the hell can I find a turbo mount gasket (the one between turbo and exhaust manifold) as I had to recycle my old one and now it is blown

hey guys picked up my turbo today

got it for $300. It LOOKS to be in good condition although the dump pipe was still on so i'll havta take this off tomorrow to check the exhaust turbine...bt the seller had a good story so i trusted him...hehe

anyway it had abs no shaft play so looked ok...pending whether its got exhaust blades now

it was off an r33 (apparently series1) but it had 45V4 on compressor which to me is actually a very new r33/34 turbo...it has also got a steel compressor instead of nylon...go figure...

anyway photo-xl: i'll be re-using my old turbo to exhuast gasket as well...so hopefully mine won't blow

so if anyone knows where to get this gasket (cheaply)...u'd prob be helping us both

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
