You do lose VCT. The stock GTR cams give really doughy power delivery under 5K but over they go like a cut cat. Ivan Tighe Engineering in Brisbane can regrind the GTR cams for about $300 to give a little extra lift and profile to work with the hydraulic lifter, but you lose VCT so Poncams always seem to be the preferred choice.

can you use gtr valve springs in a gtst.....

No they are a larger diameter got some free with the gtr cams i bought for my rb25 Neo, i got the solid lifters so these cams can go in although the Neo cams are fairly good the gtr cam on the inlet side is slightly larger and does away with the NVCS, the exhaust has slightly larger duration on the gtr but less lift so i'm leaving that cam in just gotta get the baby going now!!!

Hope this helps!

How do you go with RB26 gear into an R32 RB25? i have just brought a 26 head with the plan to loot it & modify either an R32 or R33 rb25det head to suit.

which would be better? as i have both, and are prepared to modify anything i have to.

      R34 Gtt Wheel Offset Advice

      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..

      R34 Gtt Wheel Offset Advice

      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.
