upgrading to lets say tomei stage 1 proncams would give you more lift and duratiopn and that'll improve mid-top range! but cam gears allow you to adjust them to bring boost on earlier and so, but i'm no guru so someone else might have to explain! but my plan is to just get an exhaust cam gear and run the standard cams which i was told it'll be better for the power i'm aiming for!

how much of a difference would cams and cam gears make?

sorry to steal your thread but since its about lag and power

how would a gt3540 off an xr6t go on an rb25?

the gt35/40 from a xr6 is too big for a standard engine coz i think it runs a 1.06 rear exhaust housing internal gate, to make it more responsive maybe put a .63 exhaust housing on it

ive got a gt35/40 .82 housing and external gate on my forged rb25 engine and its still laggy even with cams and cam gears, what brings my boost on quicker is my 6boost exhaust manilfold but when it comes on to boost at about 3,700/4000rpm it hits HARD!!!!

do aftermarket exhaust manifolds make much difference? any1 selling a decent one?

they suppose to give you better flow but are only worth upgrading to if you want a top mount turbo set up or using a bigger turbo on a lowmount setup, ive noticed the stainless steel manifolds crack around the welds, but they give ya exhaust note a crisper sound

if u wanna go aftermarket get a tune lengthed manifold made of steampipe

on a internally standard motor stick with the standard cast manifold and if u wanna run a bigger turbo use a spacer plate

Ahh I see, I'm not chasing too much power, id be happy with around 250ish at the wheels with response on standard block... trying to get the car setup for track/hill climb. Working on a budget and xr6t gt3540's seem to go fairly cheap.

      After market rear camber arm adjustment

      By V35Newbie · Posted

      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.

      Continental have consistently beaten the absolute shit out of every other performance tyre in Wet/Damp/Cold conditions and give up a little bit of time (half a second at most) in the dry. Almost like it's engineered for German conditions or something. I'd def give those a try.
