i suppose you could reuse it if its in ok condition, i just that you can pick up a new one for around $20 so why not change it, it would be a real pain if you had to pull it all off again to change it out if it doesn't seal up properly. the nuts should be up tighter than that, but they do work themselves loose over time (and by time i mean years) with the heat, thats why the locking tabs are on there.

how did you go removing it all, easy enough?

To remove the turbo was ,very easy,much easier than installing the SS.dump pipe ,the six bolts that hold the dump are going to be replaced (10.85 for 4 bolts and 2 studs with nut)I will need to retap one of the threads of the turbo ;easy to do ,24 mm. water lines were easy so I think the hardest part was all the pieces I took ...so yep excited to put the turbo back and see the increase in boost( Tao at Hypergear hiflowed it :ermm: )so after that need to save money and get the timing belt change done(hard to save money thinking all the mods that can help the new turbo)Tao told me that with the right mods it can run 250Kw. to the wheels...tempting very tempting (where do I sell a kidney?)

After a week of driving the car,it feels a bit slugghier than it use to be(bigger steel alloy turbine)so I need to change my way of drive .

Now the interesting bit, this morning took a bloke that works with me for a spin around the block where I work,the stag was in auto ....pedal to the metal ,it took of 1 to 1.5 secs after, got in boost and SPINNED THE WHEELS :) , man this is going insane never imagined to burn rubber on the stag (and only on 12 psi with basic mods...).

Very happy with the power figures of the Hiflowed turbo...

Now I want MORE....

(a very special thanks to stao from Hypergear) :P

I know what you mean about having to change your driving style. no more trying to quickly pull out onto the road or around a corner in busy traffic, got to take the lag into account lol

What ecu are you running Freddy?

What ecu are you running Freddy?

I 'm runing stock ecu,installed and SAFC2 couple of months ago(never tuned),now it feelslike "why in the name of...I didn't buy a nistune in the group buy?????" but,never wanted to hi flow /upgrade turbo...until stock failed,so I had two roads,buy a second hand stock one or hi flow decided on hi flow because they gave me one year warranty(you never know about second hand turbos...)

and just to clarify QW32, the current mods are:HDI boost controller @12 psi , Xforce 3" dump/front pipe, Catco cat ,Fujitsubo legalis catback and Apexi pod filter...

is stagea twin turbo ?

Mine is a 1999 RS4V so it's single turbo RB25DET NEO engine de only stagea with twins is the 260RS wich has a RB26DETT engine...

      I mean this in no disrespect to u mate; Are there clear tagged examples/explanations in our SAU forum for example, in my interest, this is how to do R34 Gtt suspension the right way? U guys did so much taking risks with experimentation that deserves recognition and those results helps us morons take the RIGHT path to buy quality / buy once. 🍻

      Pretty much what you'd expect at that power level. Hypergear turbo, long list of supporting mods, full Haltech catalogue, etc.  I'd say this goes for most drivers, suspension is still a dark art for most people. And it's really hard to convince someone how much better their setup could be...

      Hmm... From my experience you get about 0.25° camber change per mm of RUCA length change. So, to correct from -2.5 up to less than -1° (or, more than -1° if you look at the world as a mathematician does) then you'd be making 6-8mm of length change on the RUCA. From a stock length of 308mm, that's 2-2.5% difference in RUCA length. My RUCAs are currently very close to stock length - certainly only 2-3mm different from stock. I had to adjust my tension arms by 6mm to minimise the bump steer. That's 6mm out of 210, which is 2.8%. That's a 2.8% change on those, compared to a <1% change on the RUCAs. So the stock geometry already has worse bump steer than is possible - you can improve it even if you don't change the RUCA length. If you lengthen the RUCAs at all, then you will definitely be adding bump steer. Again, with my car, I recently had an unpleasant amount of bump steer, stemming from a number of things that happened one after another without me having an opportunity to correct for them. I only had to change the tension arm lengths by 1mm to minimise the resulting bump steer. (Granted, I also had to dial out a lot of extra toe-in in the rear, and excessive rear toe-in will make bump steer behaviour worse). Relatively tiny little adjustments having been made - the car is now completely different. Was horrifying how much it wanted to steer from the rear on any significant single wheel bump/dip. And it was even bad on expansion joints on long sweepers on freeway entry/exits, which are notionally hitting both rear wheels at the same time. My point is, the crappy Nissan multilink is quite sensitive to these things (unlike the very nice Toyota suspension!). And I think 99.75% of Skyline owners are blissfully ignorant of what they are driving around on. Sadly, it is a non-trivial exercise to set up to measure and correct bump steer. I am happy to show my rig, which involves nasty chunks of wood bolted to the hub, mirrors, lasers, graph paper targets and other horrors. Just in case anyone wants to see how it is done. I'll just have to set it up to take the photos.

      What do you have in that bad boy ? Ill go with the 725cc since I'll be going with Nistune ( would definitely like more engine protection but Haltech is too far out of reach at the moment... plus, Ill probably have a pretty safe tune as its a daily, not gonna be chasing peak power 24/7 ahahah ). Are Xspurt a safe choice?  Pete's great. He didnt mention anything about traction arm length so I reckon it may be good. When I get some new wheels/tire later down the road I'll ask him about it and get his opinion on em. I heard from Gary that you've got the bilsteins too, are you running the sway bars too? and what other suspension goodies do you have installed or would recommend?
