Hi guys...

My brothers just bought a 260z which has been fitted with a RB20det motor which was not running.. The turbo was the obvious problem so that was the first thing to replace..

After we took the turbo off we realised it wasn't an RB series turbo as it was only oil cooled.. Took it to tilbrooks where he told us its off a DR30 (fj20).

I've had a bit of a look through the internet trying to find out some specs on the turbo and wether or not it would be a good match for this motor . I can't find anything ..

I'd like to know wether it would better to put an RB series turbo on it (vg30 or R32 ball bearing) or just put another FJ turbo back on it?

Is the FJ turbo ceramic? how much power can you get out of them in standard form with some boost..

Any opinions on what we should do would be greatly appreciated! as the zed needs to get back on the road soon as possible.

I know the FJ that was intercooled had a water cooled turbo and these were smaller than the early turbo fj motors. The smaller version made 160rwkw on 14psi, so if it is the bigger verison that i would assume it should make more and could run lots of boost, no ceramics. So get it rebulit, $300 or so, and run it, it will be a little more laggy but not too bad.

cheers fellaz!

hay clint so you think the FJ turbo isn't such a bad choice? i've got one lined up but i'm not sure which motor its off of... how do i tell if its the intercooled or non intercooled turbo.

If the turbo can do the same job or better than the RB turbo it would be much easier choice to get the FJ.. (straight bolt up)..

You say "$300 or so"... do you mean thats how much it is to rebuild these creatures or to buy a good second hand one..

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
