Nic Posted December 11, 2014 Share Posted December 11, 2014 I use to run 256/264 cams with the stock turbos and GReddy EMU, then with a GT35R and HKS F-CON Pro. Quote Link to comment Share on other sites More sharing options...

Geo Posted December 11, 2014 Share Posted December 11, 2014 had this set up on the black ridox i had dude, found it helped with low end power. im going 264's on this build though, Quote Link to comment Share on other sites More sharing options...
Nic Posted December 11, 2014 Share Posted December 11, 2014 Cool thanks , did you run different durations on inlet, outlet? They were HKS cams inlet 256, exhaust 264, I was advised back then that this was the best setup with the stock turbos. Quote Link to comment Share on other sites More sharing options...

Nic Posted December 11, 2014 Share Posted December 11, 2014 thanks, did you 256/264 cams with 35R turbo , I am going the same route with a 35rGTX Yes ran the same cams with the GT35R, there's a dyno graph and full spec in my garage Quote Link to comment Share on other sites More sharing options...
Jellybean Posted December 11, 2014 Author Share Posted December 11, 2014 Yes ran the same cams with the GT35R, there's a dyno graph and full spec in my garage thanks Nic, I am currently looking at the Tomei 264 PONCAM's as you can run them with OEM valve springs due to the higher lift or 9.5 versus 9 on the HKS But my tuner just text me to get uprated Valve springs , now its just getting $$$ lol Quote Link to comment Share on other sites More sharing options...

Ian C Posted December 11, 2014 Share Posted December 11, 2014 Can't see why you'd need stiffer valve springs for those cams? They are only really for higher rev limits to avoid valve float, or for seriously steep cam profiles. Quote Link to comment Share on other sites More sharing options...

Nic Posted December 11, 2014 Share Posted December 11, 2014 Did they make a difference on stock turbos at 1.2 bar, worth getting? With the stock cams you see a drop off in the power curve before the rev limit, with the HKS cams it kept pulling to the redline and the mid range pull was noticeably better. When I fitted the HKS cams I also fitted bigger injectors and EMU, which made roughly an extra 30hp with the car dynoing at 430hp at 1.2bar on the stock j-spec turbos.

Thanks , No EMU at the moment or injectors ; price depending I might hold off Quote Link to comment Share on other sites More sharing options...
Benjy Posted December 11, 2014 Share Posted December 11, 2014 Thanks , No EMU at the moment or injectors ; price depending I might hold off Got some 550's, Apexi SAFC and resistor pack in the classifieds. I was going to use them with my 264's, but I'm going single. Quote Link to comment Share on other sites More sharing options...
