    Do you have any dimensions from the jenvey throttle bodies that people use on the micra ? spacing between the bodies , what the size is the bore on the manifold side , is it the taper sf bodies most people use ???

    I spoke to Andy at ap about rods before , I think they had over 160 on the last one I believe

    I see 👍 Have people tried different design exhaust manifolds other than janspeed. ?

    I will see if I can find the book , what equation are using to calculate the theorical bhp , is it determined by revs aswell

    N No standard valves but lots of head work inc welding up parts of inlet side to have good airspeed

    this is the figures for the exhaust port , it made 152 bhp on the dyno ??? and i think there is a little more to come , as the janspeed manifold really isnt very nice

    No all good here , although it is on coilovers on the back of that could make a difference I am currently doing a design for independent rear end but that's along way off Didn't think rear links were all that trick amongst all the other pictures 😀

    yep , squared up the rear axle a treat , improve the thrust angle

    on a couple rallies when idling for a long time queuing for the start the temperature would rise as the fan and standard rad started to struggle so i made a new rad then i decided front panels are excess weight so got the grinder out again then just aswell improve the engine mount and...

    i haven't got the figures to hand as this was in 2015 and cant remember where i put my book at this point i was checking lift difference to help make a choice of camshaft

    Not been on here for along time thought i would share some of my original engine build pictures and other bits and pieces if your interested bit of R & D windage tray this is the build that made 152 bhp @ the flyweel had to get a special starter made as i was a bit keen on the compression
