At this stage I'm not sure, considering taking this oppurtunity to get out of the game for a while, as I've owned the car for a year or so and only done 5000-6000km in it its hard to justify how much money I spend on it.

Have got a few options but might have to deny the dream path of glory ;)

Hey there Driver - the real question here is can you afford to be replacing turbos when you get your car?

It seems like a bit of a lottery as to how much boost they will hold - I was running 14psi when one of the turbs spat the wheel out the ar$e end:Oops:

Had to buy some 2530's to fix the problem:elaugh:

Steve is a total nutter (j/k steve)...oh, & he owns a performance workshop so he can repair things a little cheaper since he does all the work. Keep pushing em Stevo you'll get those turbs soon enough:D

Yeah i run 16 on then but im unsure if they are completely stock turbos have not had the car that long and still finding stuff out about it, was running on about 16 when i first got it ad 10 on low.

On this question how much boost should the fuel system keep up with?

cause just the other night my electronic boost controller scewed up and i wasnt really paying attention to my boost gauge but i thought to my self damn the car seams to be hammering and out of the corner of my eye when i accelerated my boost gauge went past 20psi and i was like ahhhhhhhhh but the wired thing is it wasnt detonating was running nice and the turbos seem fine and it wasnt just for a second it was on 20psi of a good haul... but i was so worried afterward. would the stock system be able to handle something like that?? or would there be something no standard there?

its really a lucky dip when getting stuff imported.

but the wired thing is it wasnt detonating was running nice and the turbos seem fine

As they say, by the time you can audibly hear the car detonating from within the cabin, its too far gone.

We managed to squeeze 210awkw out of mine before the fuel pump started maxing out. Some get a little more, some get a little less.

mmm well thats ok cause i have an after market fuel pump know that for sure apart from it saying on the engineering papers you can hear it :D

but damn if it was detonating im sure the engine would have suffered but there is no signs of it, engine still have good comp... or a i was just really really luck i got a new controller in there since so no more going above 15 for me

Clarification: So 1bar worth of boost on the stock turbos seem to be okay? Is failure past this because of the actual boost or the fact that the turbine shaft speed is too fast causing delamination?

The reason I ask is because I am about to undertake up grades in the way of a competition dump pipes and y piece as well as a retune on the dyno. I already have a larger free-flowing FMIC and pods. What worries me is that with all these mods I will have less restriction in the system and therefore less boost. If I then up the boost to 1bar I would imagine the shaft speed will be greater than a near standard system with 1bar.

Am I on the right track? If so, should I tune for 0.9bar or even less?

So is it the boost or the shaft speed?

So is it the boost or the shaft speed?

Just jammin here but I assume heat would be the cause. Differences in thermal expansion between the metal shaft and the ceramic exhaust wheel could cause it to detach...

Whether the heat is a result of exhaust restriction or excessive shaft rpms would depend on the setup I spose.

If so that is good news, as taking out restrictions should also drop the thermal loading. I am putting on 9in long dumps that are ceramic coated so it should keep a lot of heat away from the turbo and engine bay.

Does this sound right? Can anyone concur?

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
