I pulled off the oil feed line to my turbo(rb25) and found that the bolt part of the banjo fitting only has a tiny hole to let oil through, its not dirty, its just very small.

Is this normal? Some kind of restrictor?

Id like to make sure its right before i put it back together.

Also will silver solder hold ok on the fittings on the turbo lines, i can make new lines if its good.

I tried to unsolder one(need to modify water out line) and it glowed bright orange but didnt unsolder. Nearly melted it. Whats the go with that?

Small hole is normal yes. It restricts the amount of oil going to the turbo. Too much and the seals will fail. Just blow them out with some compressed air.

Not sure about the solder part, however it doesn't sound like the best option.

Well, it tells you that it wasn't silver soldered together, for a start. If it was anything similar to that it would have been brazed together, but I'd doubt that they'd even use brazing in that application.

Aftermarket braided is not the best option, but the most convenient.. New metal hard lines are best.

If you do go braided, make shure it's a teflon lined/higher temp hose, keep it away from the manifold, use heat sleeve and replace every couple of years. Oh and don't try and bend the hose too much.

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
