you'd be best off doing the dump/front pipe as well. then you would have to run it at stock boost as it would flow more air than the stock one, so if you went higher you may hit rich and retard. other than that it would be fine.

as he sed, finish ur exhaust, buy a boost controller and an ecu and tune it. i wudnt run it for too long or give it too hard until uve tuned it, just to be on the safe side.

im running slide hiflow,full 3" exhaust n dump, cooler,walbro pump and about 14psi...it feels good but the stock ecu holds the hiflow back something bad..i mean i can barely pull away from stock 33's that are running cooler/exhaust and 14psi :laugh:

Ive got a highflow, sitting there waiting to go on (found a R34 gcg highflow at a price i couldnt pass up).

batmbl split dump and highflow cat

catback 3in

Turbosmart eboost 2

I ran my standard turbo at 10psi for only short periods. Would the highflow move more air at stock boost than the standard at 10psi?

Im thinking if i run it at standard boost, and set the wastgate pressure to open up at low boost (eboost 2 gate pressure function), will this be ok to cruise around with for a while. Then i can sell my stocko turbo and get FMIC or more likely a PFC while they are still around. Also on the cards is fuel pump and injectors when the $$$s allow.

cheers

I realise that boost is only relative to each specific turbo. Which is why i ask if a gcg highflow moves more air at stock wastegate pressure than the standard turbo at 10psi.

Which also leads to the question, what boost is the wastegate spring set to on A- a r34 turbo, and B- a r34 gcg highflow turbo (sydneykid some help maybe :D )

cheers

      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.
