hey i have started buying parts for my skyline (greddy style intake, top mount exhaust manifold, stealth intercooler, haltech ecu) but now i want to know couple things about this turbo im looking at, it has different size trims or A/R its a T04Z ball bearing garrett . im looking for one to give me quick response and im only looking for around 400-500 hp to get out of it, i know smaller the quicker but when would it be to small and start making me lose top end power?

different A/R .70 .84 1.00 1.15 1.32?

also i only have standard injectors so what size should i go....550cc or 740cc.

a t04Z is a poor choice turbocharger regardless of trim or housing sizes for 298kw or (400hp)

id recommend checking out the GT30 series instead and you will effectively have a better overall power band

the power band is the difference between a lag monster (read T04Z on 2.5l) and a progressive turbo setup GT30 with external wastegate

browse the rb25 turbo upgrade thread, pick your power and look at what mods and turbocharger combinations they have used

this saves guess work and "will this be laggy" type questions as you can see all the mods and what turbo spec etc

      What can't be done with a little bit of decking board or similar timber bolted to a hub flange via 2 wheel nuts is not worth talking about.

      R34 GTT idle problem

      By silviaz · Posted

      I noticed something. On the tps sensor and the sensor behind the adjustment screw is adjusted towards the far left. Are these screws supposed to be centered? (this sensor was in the same position before the tune as well)  Also attached a photo of where my car usually idles at when warm (sometimes a tiny bit above that). I think I might have screwed up the calculation and it might have better than I thought lol at 750rpm still not 650rpm though.

      So for both general interest of engine health, and to rule out any coolant/oil issues, I organised an oil analysis done on the 125,000klm oil Results below, all good, just a bit of fuel dilution which I'm not too worried about

      This is actually a really good way of measuring what wheels fit. If only there was a similar measurement between hub face and suspension :p That said, it's probably pretty simple to actually measure it all with the wheel off the car for the rear. The front is a bit more complex but..

      Being the top Google search result for R34 wheel-related inquiries, lemme throw down my experience. I calculated that 100mm from hub face to wheel face is about the perfect fitment for my ENR34 sedan.  I've been running 18x8.5s, ET35, with a 1" spacer. So, 8.5in to mm = 216mm. 216/2 = 108mm. 108-35 = 73mm. 73+ 25 (1" to mm) = 98mm.  If you wanna get close to this on dif widths, here are the offsets you'll want: 9" - ET around 15mm 9.5" - ET around 20mm 10" - you're crazy, but ET around 30mm All these should fit perfectly on a non-widebody, non-GTR Skyline. Note that it's probably the absolute max, and you're probably better off running a couple degrees of camber in this config, but it looks great, super flush.
