small update: we finally decided on a camshaft Was originally thinking about going through http://www.wadecams.com/ who have their own GTiR grind but was very lazy (probably for bolt-ons) and their billets/machinery couldnt do a very high lift. After much research and discussion and learning about camshaft theory (yay) we decided to go for a higher duration but lesser lift. So hopefully going to revive the low-mid end, compliment the turbo and get the most out of the cam before 7500rpm. But of course without any comparison or spec cards its all guess work really. Only one brand had reasonable lifts for the GTiR so choice was pretty limited. Just ordered some JUNage: Intake 272 degree, 11mm lift Exhaust 272 degree, 12mm lift While the 280's were tempting, they were the top end of the scale and I didnt really want to risk getting something that was doing more harm than good, so backed it down to 272. The JUN's are made to order, so its going to be a 3 week wait + delivery. Once they arrive, we'll dial them in and hopefully have some room to play for the tune. 272 is still an aggressive ramp, so reducing weight on the valvetrain cant do any harm. JUN and Tomei springs/retainers cost an arm and a leg, so bit the bullet at got BC dual springs and Ti retainers for $350US + delivery (wew). After street tune, bedding in the engine (1000kms, 2 oil changes) and final tunes we'll probably inspect the head to see how its coming along. Maybe after a few track days we'll do it again and if the springs are looking cactus or somethings not right we might mix up the cams and/or springs. Also got the head powder coated, but the bastards sand blasted underneath it too so a quick wash isnt enough. the tacks will be grinded off to remove the baffling and make sure its all out, then screwed back on and sealed.
