Block Posting 101 w/ Jeff Frank
Block posting, this is an alternitive for those lame *** block guards, and for people that cannot afford to sleeve there blocks. Posting and Pinning has been around for several years. It is used in Nascar and other forms of racing. Larry (theoldone) uses this on lots of his Honda engines he builds, and he actually did my built ZC w/ pins. I figured this time I could do it myself, since it didnt look to hard.
First starting off with some pins/posts. Basically there are little threaded studs, that are made up of the exact same alloy as the honda/acura aluminum block. This is so when the block heats up and cools down. The studs will do the exact same. I got this set of 12 studs from (endyn) for 35 bucks.
Drilling 4 holes in the center of each sleeve about 3/8 of the way down (from the top). Why not put these pins at the top of the cylinders? well, all cracks in sleeves normally start midway up.
Then threading the holes in the block with a tap. You will need 2 taps for this, since the main cut tap with the tapper will hit the sleeve real quick, then you will need another tap that has the end cut off, so you can get threads all the way through the outter block.
This is the intake side, we use 2 pins per cylinder, Larry claims he has found the thrust axis points on these blocks, thus the intake side having more load, and using 2 pins insted of one. This makes it kind of a bitch, because there really isnt the best spots for this. I kinda went wherever the ---- I wanted, anywhere that was flat. I really didnt feel like cutting the webbing off the block to make it absoultly perfect.
The pins are torqued to 2inch pounds.... YES 2 inch pounds, that's like hardly anything. Anything more could distort the sleeves. Be sure that the area around the pin hole is really clean, then I applied JB weld on the threads and all over the stud so it would stay in place. Larry says its not a good idea, but I think he said this just so Endyn wouldnt look bad "ya use JB WELD" LOL.. He recommend using the Devcon liquid Aluminum stuff. I think JB will work just fine. (we will find out soon enough
Be sure to clean out all the metal shavings really well, and let the epoxy sit up for atleast a day before you install the engine.
All done... btw, this is my B20b Block that is going in my Red CRX... CRVtec

Re:Block Posting 101 w/ Jeff Frank
I thought you were supposed to get the block honed after you do that
? Can't wait to see if this works out for you. Nice write up.

Re:Block Posting 101 w/ Jeff Frank
thankz jeff for the write up, i talked to sonny at http://www.muller.net/crx/, and he told me when you put in the screws dip them in epoxy, then screw them in...but i think it doesnt really matter...and he told me after doing all this, its best to hone the block...
im also in the process of putting a B20Vtec Turbo Into my EG hatch, how many pounds are u planning on running?

Nice write up.
In your race ZC what type of sleeves did you get done?
I have seen a "Godzilla Sleeved" d16a1 from golden eagle and they put in a the sleeves and they literally take up the entire upper half of the block. There are smalls passage ways to allow coolant to flow around.
The godzilla sleeves looked way different than your race ZC or the D16a1 block I have been following from sonny's muller.net site.
I'll post a pic when I can get one.

Re:Block Posting 101 w/ Jeff Frank
thanks for the block pinning info! i want to pin my zc block and maybe get new internals but i don't want to spend all the money on balancing, honing etc i guess i might just pin it and keep stock internals to avoid machine costs.
jeff, what did you do on your built zc.. did you post it and replace the internals? what kind of machine work did you have to get done?
