Hi guys. I found a weeping welsh plug under the front turbo on my r34 gtr. And now I'm thinking I might as well pull both turbos off, do all the Welsh plugs on that side and may as well get the turbos hi flowed while I'm at it. So can anyone give good feedback of turbo builders in Sydney?

Thanks in advance for your input.

Stao where do you think -5 would make 20 psi on a RB30 bottom end?

Might be too small. We've made an 55mm exhaust wheel for RB2630 application, and that should do.

For the -11s I meant the 2871s

Depends what you're after. -5's won't blow till 9000 rpm on a 3.0, so if that's what you're after, wrong turbo.

A grunty, lazy 400-440 kw on E85 with a sorted setup without having to spin it to the moon, perfect.

Ok just finished ripping out the turbos......what a bitch of a job. Dreading putting it all back together. All welsh plugs on that side also out, ready for new ones...

Turbos have a little bit of end play and oil sitting on the inlets especially the rear turbo. So I'm thinking might as well give them the high flow treatment while out.

I'm thinking -9 cause I'm not really going to do any other upgrades as I want to keep the car as stock looking and standard as possible.

What's everyones thoughts? Car only has wheels, suspension, exhaust, and a little piggy back power tuner wired into the ecu.

Oil sitting in comp covers, inparticularly the rear one, is normal for a GTR because of the factory breather setup and I'd say there is oil in your BOV return pipe too

What PIGGAZ said, -9s and a proper standalone

Cool,

This would be awesome in a dirty 26/30 where you don't touch the bottom end and don't want to overspin it but still want massive midrange power and street driveability

edit: OP you will love your car again like the day you bought it if you boost up on -9's with a real ecu. do it!

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
