ok well since blitz mentioned he wouldnt mind some info/pics on the build ill start a dedicated thread.
everything is being assembled at home by myself and my dad, except the head which is being assembled by a local perth shop (still waiting at the moment). who ever reckons engine buiding is hard are fools, i reckon its piss easy, and its more a pain for the machinist as he sorts everything together and we just assemble as per normal. while double checking everything and setting suitable torque on the jun studs/etc etc. in the past 3 days of doin the assembly (after work at night) we have thoroughly washed and cleaned the block, installed the block core plugs (12 big ones, 7 little ones.) and oil squiters are in, bearings/crank/main stud girdle are all in and tightened. next its sorting the piston ring sizes, and then pistons and rods can go in block (rods are already connected to pistons). so all in all the bottom end is almost done, and the head i am getting back this wednesday hopefully so i can bolt that on (then paint the block) and then all the accessories go on... check out the pics below and look at the smoothness of that crank hehe, its a shame it gets hidden becuase its a master peice  cheers Brad       --------------------  |

engine building isnt hard for people with mechanical thinking, but wait till or if something goes wrong and all the blame can only rest with yourself, and it could be a silly mistake that a professional that works on engines everday wouldnt make. (but they sometimes make other mistakes). Looks good mate good luck with the build, should be a real nice thing when finished!!!

out of interest, why are the bearing faces still black? i would have thought they'd need to be linished back to bare steel before assembly.
nice looking piece of gear though, looks a lot neater than the goddam RB30 cranks i have had out. balancing holes drilled all over the place, looks like a dog's breakfast. edit: i don't understand why people pay so much for an extra 100ml capacity when you can have an RB30 for such little cost these days. the only advantage i can see is the giant revs the 2.7 is capable of, but that's still a moot point as the RB30 can make the power more easily on lower revs. i guess you can keep your engine number though |

QUOTE(StockyMcStock @ 11 Dec 2005, 08:02 PM) out of interest, why are the bearing faces still black? It's a phosphate coating for corrosion protection. It also helps during break-in by retaining oil on the working surfaces (coating is porous). Bolting things together is fairly 'easy', the time consuming part with building a performance engine are things like checking bearing clearances with plasti-gauge, which is tedious. |

i got the crank/rods/pistons second hand but unopened in boxes
the stroker kit with crank/rods/pistons is about $9000 on greenline i think. i only got it cause i got it cheap and i want the revvy nature of the 26 to remain. i used to own a rb30et and they just feel too much like a deisel engine. fall asleep waiting for it to hit redline :lol: each to their own i guess cheers Brad -------------------- |

It has taken me around 9 months at a well known performance work shop (NOT RACEPACE) here in Melbourne. I still haven't got it back yet!  I really like the JUN 2.7 kits they are of the highest quality and its high revving capabilities is another positive. Good selection in my books! Best of luck with the build! |
