The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

Left it for now. Was up too 262kw at 5500rpm 14.5psi. Was just having a play tonight and good to hear it running.

Surge tank and lines are on the way after ur very helpful input Matt. Cheers for letting us know about urs.

Fark im so keen to get mine on the dyno now.

Looks very similar to GT2871 results on a neo 25, I have a turbo that is highflowed with the same wheels that looks very similar to that graph though less power due to the restrictive rear housing.

Be interesting to see how well this turbo performs when you finish the tune! Neos always seem to give fantastic results.

Yeah.... Nah! It doesn't haha

Neo usually make a little less power actually because they are pingers

The few tuners I talked to seemed to think they always made more power as they seem to rev more, seen two results that seem to point that way, eg matt from nistunes r34 that makes 310rwkw on a 0.63 gt3071r with poncams on only 18psi, dyno sheet is on here from a reputable dyno/tuner, and then mine which is a highflowed rb20 turbo with the rb20 rear housing still that makes ~258kw on only 16psi

On the same dyno for both?

Regardless from what i have seen, neo's seem to get a bit more compared to regular rb25det's with similar bolt ons.

Yep both on same dyno same tuner. Pete from nistune and the morpowa dyno in adelaide, he told me every neo he has done has gotten fantastic results compared to the r33 engine, "chalk and cheese" were his words from tuning multiple neo and r33 motors.

I also had identical everything just changed from r33 rb25det to a neo rb25det with the r33 intake, all the same sensors, hoses, literally everything the same just the block changed and went from ~236kw at 18psi to 258kw at 16psi.

That's a solid improvement!

Is there any rewiring for sensors or the loom etc needed to put a neo rb25 in instead of an s2 33 rb25 or does just the ecu need to be changed?

The 34 looks like it will put up a good number, I think you'll shite 400kws in Jez

Im curious to see when this turbo maxes out.

I know Kurtis is now a power junkie but this thing is aimed at max response with strong top end. I have the goal set at 350+.

Time will tell with my one too. Its a 700hp turbo. But same again its main goal was response and 380+

      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.
