Thanks very muchly. What's a new chra worth if worst comes to worst

That I'm not sure about, but the JB CHRA will have the longer life span if anything.

Nothing to worry about.

Wait what!

You changed your mind again?!

No, no.

Before my budget crisis I had a PT 5558 on order. Shit happened and I ended up selling my 6boobs etc and went factory low mount with the SS1PU.

Nothing has changed, motor is mostly assembled (turbo attached now). Just need a new sump pan (mines rooted), rear main seal and ancillary water hoses then I'm bolting it in. Have taken a few pretty photos so once I get closer to results time I will make a thread of some sort. I prefer to lay low when I can and preserve identity but I do want to share the SS1PU SR experience.

I know there have been some failures in the past, but im sure thats old news.

In general JB's have a longer lifespan than BB's and are overall not as delicate.

The main thing I dont like about the PT BBs is that they arent water cooled. IMHO BB's should always be water cooled, too delicate to not.

water cooling is to take heat away from the turbo, which is oil lubricated and cooled also. remembering the turbo gets hundred of degrees going through the back side which is bolted directly to the CHRA you want to get as much heat away from the rotating assembly as possible.

Admittedly I do not follow the supra forums and PJ you already know I've never used a JB PT. Dunno whats to be proven here, but you guys win already.

I did plenty of reading myself when I was going to buy one and found plenty of posts like this saying 'get the BB' but hardly anyone actually having one fail in the past 3 years - I could be ignorant and not reading the right places so who knows. I'll just keep my mouth shut in future, no use trying to help people and share what you think you know when others are only going to shoot you down.

Yay ball bearing party, lets all dance and clap.

Theres been heaps of failures in last 3 yrs...people have been reporting them as being worse as far as i can see

The GFC may have forced there quality control to be not as good as it was...

people aren't shooting you down..no need for knicker nottage..lol, its just you said " you are sure its old news"...i mean

you can't be sure at all? i'd never ever ever buy one, now or in the last 10 yrs

cheers

darren

Isn't water cooling only for the cool down after engine shut down? If you have a turbo timer or let your car idle after a drive then I'm sure it'll be fine

after many discussions with my turbo guy, that was my understanding also...

Be interesting to see how these oil only Precisions last,, should be fine if shut down correctly..

I like the V-Band turbo/manifold idea too, should take care of any gasket issues. watching this thread with interest

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
