Re: B20 non-vtec FAQ Guide including P8R head information
I just spent 30 mins searching for crane rockers..
I found info for B18c but not for non vtec heads. The promising threads that looked like there was a part number or info were non existent when clicked.
If someone else has savvy searching skills and can find a part number, there might be a set of someones shelf for sale somewhere in the US

Re: B20 non-vtec FAQ Guide including P8R head information
Looking for some help with my '00 Crv;
It has the B20Z engine, and I keep getting misfires on all four cylinders. Did Ngk plugs, Ngk wires, OEM cap and rotor, still had codes come up. Pulled the head, valves were white/burnt a bit, replaced headgasket while it was apart, still have codes. Going to grab a P75 complete head and intake, as I assume the orginal P8R is at fault. What would my best setup be, seeing as I have all the parts from both heads? Looks like just swap the P8R intake cam in, and run the P8R intake manifold right? Thanks for any insight.

Unless you did a swap in the past, the head on there is already a p75... Not a p8r.
Get the new head checked out before you do anything with it.

Re: B20 non-vtec FAQ Guide including P8R head information
Youre right. I was reading so many different things yesterday, I messed up. So I have the high compression, and that still uses the p75 head. Well that makes sense, when I was checking part numbers between a '98 and '00 Crv everything was matching up. So an older head will not lose power, as its the block/pistons/manifold with the box on top, that make the difference. Awesome, trying the last cheap fixes today, fuel filter and swapping injectors around. If that doesnt work I have a head lined up. $100 is fair for the head and tall manifold I think, even though I wont be using the manifold. Thanks

Re: B20 non-vtec FAQ Guide including P8R head information
I need the help of someone with a P8R who has had the guides replaced, I have a huge problem. Machine shop called and the non vtec valve guides I purchased are severely undersized. The valve stems are according to them, 6.6mm in thickness compared to the guides which are 5.5.

Re: B20 non-vtec FAQ Guide including P8R head information
Eso, did you weigh your ycp pistons? got my pistons last week.. they just felt heavy to me LOL. made me get some arp rod bolts and having the rods resized.. its all at the machine shop right now with the B20B block 
my p8r head is getting repaired (something got in #2 chamber and got beat to ****.. before i got the engine) you've got similar setup to what i'm doing. i've got crane 903-2000 valve springs and TI retainers, and some crower 403's waiting to go in. i have some supertech .5mm oversize exhaust valves I'm going to use as well.
good info in this thread! keep it going!

Did you ever check the valve lash. P75 heads have some issues

Re: B20 non-vtec FAQ Guide including P8R head information
Yeah I forgot to list it, but that was the first thing I did when I got the vehicle. And then again when the codes started popping up. I ended up doing fuel filter, 93 octane and some lucas injector cleaner, and it went away, and got it through inspection. It stayed gone for about 5 days, then came back when I let it idle for ~10mins. If I just start and drive, no codes. If I let it warm up first, pending codes before I leave the driveway. Idk, I have another year to figure it out now I guess. Sorry to ramble.

Re: B20 non-vtec FAQ Guide including P8R head information
Dammit it all makes sense now. I was questioning my ability to measure when I did mine, eventually said f'it. I was expecting either .004" or .030" p2d but measuring around .010". 30.06mm gives .011" p2d on an untouched block.
I had decided that it really didn't matter since it's just a motor for the daily, as long as I didn't run my valves into the damn things. Good to know I was actually right the whole time
I think it's funny that, the more that I learn about them, these YCP/RS "clone" pistons are not much of clones at all... more like second cousins.

It's nothing special really, a super stock build with a P8R and RS Machine pistons.

Re: B20 non-vtec FAQ Guide including P8R head information
my bottom end is done at the machine shop.. picking it up monday .. they were still mounting the pistons on the rods when i came in the machine shop today. weighed the YCP type R style pistons.. 345.5 grams and piston pin weighed 96 grams.. then we weighed the stock P3F piston at 313.5 grams & pin at 88.5 grams. so stock P3F's are 39.5 grams lighter than the 84.5mm YCP R pistons.
cant wait to get it all assembled!

Re: B20 non-vtec FAQ Guide including P8R head information
Just to add some info about the block/piston/head combinations.
Mine is:
B20B block - PHK pistons - P75-7 head (99-12)
I got mine from tigerjapanese.com back in 2010 and that's how it was when I got it.
Thats mated to a YS1 tranny and LS manifold (not sure which one) boosted at 10psi and made 217whp and 209ft-lb. Stock internals.
