GTRsean Posted November 14, 2012 Author Share Posted November 14, 2012 Well just got back from Unigroup in Girraween over half an hour ago as they have been flat out!! Long story short, no good. Found a split hose on the run, the one that goes from the "twin turbo" outlet past the airbox...GRRRR So I'll need to fix that before a tune can be sorted...Well, I'll have to go back there tomorrow and get back in line once I fix it Link to comment https://www.sau.com.au/forums/topic/323011-99-r34gtr-vspec-now-stroked/page/15/#findComment-6624950 Share on other sites More sharing options...
SiR_RB Posted November 15, 2012 Share Posted November 15, 2012 Oh dam I also split that hose going from the twin turbo pipe outlet, just replace with a hard pipe kit?

bored33 Posted November 15, 2012 Share Posted November 15, 2012 Yeah, just some nice cheap ones will even do as long as they are good quality. From memory, I'm pretty sure I had the exact same problem until I replaced it with a hard piping kit and even gained me some extra wasps.

GTRsean Posted November 15, 2012 Author Share Posted November 15, 2012 Went with a cooling pro silicone black piping kit. Looks rough enough, and no more leak Oil problem was a combination of rings not bedding in yet and lack of crankcase ventilation. Once it was caned on the dyno blowby reduced very quickly. 312kw @ 16psi. 326 @18psi. Will go back in a couple of weeks for the power tune In the mean time it's Sau nats time Link to comment https://www.sau.com.au/forums/topic/323011-99-r34gtr-vspec-now-stroked/page/15/#findComment-6626588 Share on other sites More sharing options...

GTRsean Posted November 17, 2012 Author Share Posted November 17, 2012 It doesn't need as many revs and putts around happily. At the moment it's tuned to 312 on 16psi and 326 on 18. Apparently these turbo's don't boogie till 24psi...

GTRsean Posted November 21, 2012 Author Share Posted November 21, 2012 Mine are twin 3' into 3.5' front pipes as well with flex joint, then through a nismo metal cat. Getting a 3.5 inch cat back stainless steel exhaust sorted out tomorrow as the HKS one is 3' from cat to 3.5 from the back of the resonator, then less than 3 inch through the rear cannon...

r32-25t Posted November 21, 2012 Share Posted November 21, 2012 Twin 2.5 is good enough for 400rwkw on a 4L engine Link to comment https://www.sau.com.au/forums/topic/323011-99-r34gtr-vspec-now-stroked/page/15/#findComment-6634350 Share on other sites More sharing options...
GTRsean Posted November 21, 2012 Author Share Posted November 21, 2012 But you got 4L of engine telling that gas where to go lol!!!! gas has got no choice The cross-sectional area of a single 3.5" pipe is about 38 inch square. The cross-sectional area of the twin 2.5" pipes is about 39 inch square. That gives equivalent flow. Likewise, the cross-sectional area of a single 4" pipe back to muffler is about 50 inch square. And the cross-sectional area of twin 3" pipes is about 56 inch square.
