FWIW I run Kelford 264/272 9.6mm and still retain VCT. VCT is great, enables all that low end torque to help bring on the turbo earlier compared to a non VCT motor. -
Awesome effort and result, well done. I understand you wanting to get that 1.30 but the reality is this is a super quick car already with road cars being in the mind 40s, its hard to realise how much is required to go that much faster! The other thing is, having done Targa a few times from NSW, the cost and effort to travel that far to a track and city you don't know, and then deal with things not going to plan, that is a huge extra effort on top of everything. And once you've got all that sorted you need to drive it too! Anyway, well done for taking on such a big adventure, I hope you enjoyed it among all the hectic pace and pressure -
That was a really fast reply! Thank you very much. i will contact kelford. Have a great day -
Lifters (solid vs hydro) do not affect VCT. For cams, just contact Kelford in New Zealand and tell them what you want to do with the engine and that it is a solid converted 25. They'll know what to give you. FWIW... you can probably use any cam with either hydro or solids at that power level. By "any cam" I mean, there probably isn't a particular reason for the profile to be much different between the two. -
Hello from Germany, i build my RB25DET Series 2 -> Target 600hp i have now ordered solid lifters from Tomei for the cylinder head and will replace the original hydraulic lifters. Which cams can you recommend ? It is only a street car.... Maybe i order a Garrett GTW38 or something like that. and what is with the VCT ? is it blocked with the solid lifters ? Attention is a RB25DET with solid lifters! Thank you for your help
