Hi Mitch I have one in front of me, what measurements did you want? Dan

Hi Spoolup Seeing as you are hitting the bhp area where I want to be, anychance you could post up the spec of your engine? and what turbo your running Cheers Dan

Hi Guys First off just a hello from merry old England, great site by the way I'm building a RB30 using a RB25 VVT head off a R33 GTS-T and aiming for around the 700bhp mark. The car will be pretty much a full time track car. I just need a few pointers on what spec accessories to go with the engine. So far I have forged conrods, forged mahle pistons with a 8.5:1 compression ratio, these will get ceramic coated too. Headgasket will probably be a Cometic 1.2mm or similar. My main question is about the valve train set-up. I am thinking solid lifters, am I right in thinking that the RB26 has solid lifters as standard and will go into the RB25 head? Also cams, what spec camshafts would you go for with the aim of 700bhp? There seems to be quite a choice from 256, 260 and 270 degree shafts. Valves, are the standard valves happy to handle the power, or are they worth replacing too? Turbo wise I'm either going T04Z or Holset HX40, haven't decided yet. Both will supply me the power I require though The last question is what gearboxes do you run when tou reach this level of tune? I have a couple of RB25 boxes here already, and I have heard mixed reviews on how much power they can take some peeps kill them at 500bhp and others will cope in excess of 1000bhp Sorry for the long post and all the questions, but it would seem that you guys are the best to answer them Cheers Dan

Hi Guys I'm planning to be putting a NCVS head onto my RB30 block, and firstly just to say thanks for this thread, it will help a great deal I'm planning to run solid lifter in mine so I take it that means I don't have to worry about feeding oil to the lifters anymore, so I can skip this stage? Dan
