eg chassis
got the bottom end almost finished i hope i dont have to take it all apart to relieve the valve relief on the pistons

i got all the gaskets in i should have it all together soon. i got to load up some pictures but my camera takes very high quality pics and the take up a lot of space. it takes hours to load up to photo bucket, so i guess i will load them all up at one time. so far its all going together nice. i got a huge holset turbo its a vgt i am trying to figure out how to get crome to control the vgt part of the turbo it would be nice to get quick spool on a huge turbo. I read a guy can get one to spool 8 psi at 2500 rpms on a 4g63. I have also read that they dont work on a honda engine but i was also told dont waist your time with a non vtec sohc f22.

I was told the same thing...... But did we listen
Can't wait to see how this thing comes together.
As for your images being too big. You can re-size them in Photoshop or Microsoft paint. If all you have is MS Paint, open your image in Paint, go to the image menu and select - stretch/skew. Put a 25% value in both of the horizontal and vertical boxes for stretch. Kick ok. Then go to file / save as / "file_name". and save it as a jpg format. They should be small enough to upload to photobucket in no time.

i am filling my block with devcon. i would have never done this but, i took my block to get it surfaced and the guy build some big time cars. it is funny he has been building cars for 30 years. he does http://www.dcrsrt.com/ engines. he showed me what these guys where doing to put about 50+ psi to there engines. he told me he has filled a number of honda engines he built one of the worlds fast turbo sohc at one time for jeff cope. he never has had trouble with them over heating or any thing i am doing it. He done the machine work on a 7.9 sec neon and a 8 sec evo both with well over 1200 hp

Devcon eh! I have been reading up on that for use in my intake ports. seems like it is the shyte for use with aluminum. It is said to have pretty much the exact same thermal properties. It's adhesion is also supposed to be second to none. But the articles I have been reading could be somewhat biased. This adds one more item of interest to your build.
What are the costs compared to throwing in a set of wet sleeves? Obviously not even close but I would like to see some comparison numbers. In build costs and in the end the difference in engine temps.

cost well i got a can for like 60$ that shipping and every thing from grainger. I normally dont do stuff like this but since this guy has built some of the fastest engine in the our sport i will trust it. he told me that where most people mess up is they fill it to the top of the block even with the deck on a street car. he said i should fill it to about 3/8 of a inch from the top of the block for the street. You know that makes since if you look at where the heat is at on a cylinder. i was comparing a the sleeves of a f22 today to a b16the f22 are way thicker and the distance in the water jackets is a lot less.

I am going with Darton M.I.D. wet sleeves for my build. I am going with an over bore so I had to go with sleeves.
Now the 3/8th measurement you have been given is the same measurement that KMS gave me for welding in my block guard. I am guessing that in leaving that space between the head and the devcon you help eliminate the overheating problem. The top of the cylinder. Where the block and the head meat. Would be the hottest part of the cylinder, considering that is where the combustion takes place.
I have read a few DIY devcon block guard threads. Fill the block to a given height with salt, pour the devcone so that it's 1/4 inch thick and a given amount of space from the head. Let it cure and then use hot water to disolve the salt out from under it. Bore the cylinders and then your good to go!
So are you going to do the devcon guard yourself?

thats the only way it do things i normally do all my own machine work but i could not free up my milling machine to do the block decking. i do every thing on my milling machine i got to get some pics of my fixtures and holders i have made to do my machining on a Bridgeport. i am thinking of even sleeving my block on it i almost certain i cant do it.

Well if you can machine your block with a set of closed deck sleeves yourself. Honestly, F#@k the cheap Devcon block guard!

i was going to see how this stuff holds i got to buy sleeves. the sleeves are about 400$. I think i know i could make the sleeves if i can find the material. i have a lathe, heat treating oven and a cylinderical grinder. what i was thinking of doing is making the sleeve on the lathe leaving .010 over then heat treating and temper the sleeve. next grind the od and id of the sleeve to size. I wish i could find ductile iron to make them from. I have called every where to find ductile iron no body sells that stuff

i got it all blue printed and balanced. it is taking me longer than i wanted. time time time. you can buy all the parts in the world but you cant buy time. My wife works nights and i work days we also have a 10 month old baby. so i have to make time when ever i can. My mom is going to baby sit for me this weekend while i get this bottom end together.

got the bottom end together today if i get time i will put the head on the check the valve to piston clearance. I put all pics and tips on the first page so people want have to go threw the hole thread to see what all i have done. the math worked and all the parts worked fine. i have one question do i need to notch the block any deeper
