Hi guys I have a t28 high flowed turbo from an s15 on my rb25 I only just bought the car about a month ago it was going fine holding boost at 15 psi until the other day when I booted it in 2nd gear and there was a Big Bang and I blew off a cooler pipe so I put it down to that limped the car home and fixed up the cooler pipe then wen I took it out next the turbo won't make any boost runs fine in vaccume but then wen u boot it the gauge holds at 0psi I first thought I might have a boost leak but now I'm thinking its probably the turbo can anyone confirm this? If so what is a good turbo to put on I have a standard ecu 3 inch exhaust and fmic I'm looking for about the same power maybe a little bit more

That oil in the front of the housing is normal, its from the oil breather lines. That shaft play is probably not 2mm. I don't think your turbo is a problem, I think you've still got a leak somewhere. If you damaged the wheel or suspected you popped your wheel, you would be here with severe engine problems because that wheel would have been eaten by your engine.

Might be a stupid question, but does it still feel like it is making boost, or are you just saying it makes none because the gauge says so? If it still feels like its making boost it could be as simple as the boost vacuum line has come off.

Well it turned out to be a boost leak in the boost gauge line I don't know how the gauge read vaccum it was a massive crack, I went to the local truck supplies shop and bought some new 8th inch plastic hose for 2 bucks and found another small leak now there both fixed the car boosts properly only now I have another problem now at about 5000rpm in first the engine breaks down and splutters and looses power also if I'm cruising along in 5th then ease power on it begins to splutter. The car has splitfire coil packs there probably old so I'm thinking one might be stuffed I have replaced the plugs and it made no difference so I'm hoping it will just be one coil pack, buy a new one and then work out which one is failing well I'm hoping it will be that easy anyway

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
