The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

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

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

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      My BMW E39 528i touring

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
