ok. so i finally got around to doing some work. been helping others, and well just being lazy or broke, or cant decided what i want to do...
so here it is the $75 B20...that turned into the $1200 B20... fuck.
ok, so my place is a mess. really should spend a day and dump run everything that doesnt bolt to a car i currently own...
but i cleared all this space that was full of junk and bolts/hardware. so i have a good place to work from. see how long that lasts...
after i got a clean space, i filled it back with shit lol. actually i gathered up all the parts i was going to use.
once again i got a gasket set from Mizumo Auto on ebay. actually i got pistons, bearings, rings all from them. good deals.
ahh, there they are. looked for like 10mins for the thrust bearings, fell behind the bench there. fuck.
also got some more GREEN plastigauge. i only had red, cuz you dont use it for a honda? you need GREEN for mains/rods on a B-series.
King bearings, NPR rings.
one of im sure a couple Honda orders for this motor. new "ITR" oil pump, pump pickup (motor are a bearing, didnt wanna risk it), gasket and oring for both those. new thermostat also. new timing belt of course (well i did reuse one last time i guess lol) and a new lower cover, cuz the crank pulley was cutting into the last one.
block all cleaned and prepped.
it should be said that i honed this block, and cut it for the turbo (ill post better pics later), then it spent a good while in the parts washer. then pressure washed. with both main oil galley plugs removed (better pics below). to get a good cleaning (spun a bearing before, im paranoid)
then i emptied 2 cans of brake cleaner here to make sure everything was spotless on the inside!
deck all clean
front oil plug pulled. its between the tensioner and oil pump hole.
goes all the way threw the other side to this one right above the rear main seal.
i cleaned the shit out of that path. and to the oil filter. up to the head. and to the mains/crank. i got a set of brushes from HF.
assembly lube.
i have a couple different mixes here. dark one is off the shelf. the lighter one is 50/50 with some oil, and the little cup is mostly oil.
i use the cup for headbolts, cam bolts, etc
lighter shit for cams when setting up lash
dark stuff is thick as shit and sticky. put it on the crank/rods, everything else if its gonna sit for a min before starting.
there is some ARP lube back there too... but no ARP hardware in this motor, so it didnt come out to play...
upskirt.
brand new pistons... went with stock P3F-A0 pistons... didnt really research like i should have as Jeff pointed out, ballz low compression with these pistons. oops, whatever. CRX moved with them. also
cheap.
all staged up. got my specs written down in the back. id post it up, but im told my writing sucks, so look that shit up yourself. download a Helm/factory service manual.
setting up for ring gap check...then filing to spec...well beyond spec cuz im gonna beat on this shit.
freshness
so there was some talk about this on another forum (GVR4), and i have heard about it before, never done it. they drill out/remove the pressed in balls, clean the passages, thread in allens and locktite/stake them. decided i would like this motor done pretty baller. so had it done. im happy. plus he said there was a TON of shit behind those plugs...
hey look
im plastigauging a motor!
i dont do this shit anymore. but like i said. i want this motor nice.
look
waste of time...
all mains/rods spec'ed out perfect. then i did it my way, and crank spins over minty smooth. so piece of mind, and proven working....
and this his how turbohf clocks his rings. oils are somewhere on the top.
i always do top ring on the right, 2nd ring on the left.... but thats me.
ahh, feels nice to fill some holes....
damnit... look at that dish...
rear housing with new seal, hondabond, new oil pump with some hondabond, and new pickup... ready to rock...
looks like i ran out of pics. must have been done? i bolted on a couple accessory brackets, tensioner, water pump (nice used one), and some other misc shit... got pissed i cant find my upper alternator bracket i swiped from someone. then gave up for the day.
next up is the head...that i dont have valvesprings for yet. but they are on there way.
