#147056 He didnt really make any sense. cool thread though and yes know it all banned guy (even though your banned you will find a way to read this) some people sit on a computer and read all day so that they can learn and do things the right way when they actually go out do them. thats why we have a forum.

had to put my .02 in. maybe teal can weed this thread of all useless posts.

#162155 allright so I am purchasing a b20 block, so just to be sure the p72 itr pistons will fit in the cylinders? and what rings do I order? this is my first time building or ordering parts like this so I am not a 100 percent sure. and also will used p72 itr pistons work as long as there not beat up. any info will be greatly apreciated.

#162191 p72 itr pistons will NOT fit inot a b20 block

p72 itr are 81mm, b20's are 84mm. if you wanna use p72 itr pistons, get a b18a or b18b block.

#162194 oh allright cool, can I get the b20 stock rods shot peened, or is that for the b18 aswell? I just picked up a mint running b20 and I have a pr3-3 b16 sir head that is fully built with all skunk 2 goodies, so I wanna put it on the b20 and rev it to 9000rpm, I just dont want it blowing up on me so I am trying to do it right, so if you guys have any info on that it would be very usefull to me, I am trying to do this with out a crazy budget, my girl and I are trying to buy a house and get married so funds are tight.

#162195 you can get the rods shot peoned,

if your rolling on a budget just reused your stock b20 pistons,
By the honda guy
#162196 sorry about the questions but I just wanna get this right, I am trying to get a list together of the things I have to do and order,

PARTS I HAVE TO ORDER
1-some sort of high compression 84mm piston set
2-rings
3-thin headgasket to keep compression up
4-arp rod studs(should I get them for the b20 rods?)
5-arp head studs(what motor or head should I get them for?)
6-b16 oil pump
7-timing belt kit(what motor or head should I get it for?)
8-22t water pump(what motor should I get it for?)
9-can I use the b20 stock rods as long as I get them shot peened?
10-can I use the stock bearings that are in the b20 as long as they are ok, or do I have to get new ones?
11-should I get a girdle or just let it go?



THINGS I HAVE TO GET DONE
1-if I can use them, get factory b20 rods shot peened
2-have rods oversized for the arp rod studs
3-have rotating assembly balanced
4-eventually break in motor with straight 30 weight

If there is anything you guys would like to comment on then go right ahead, you will not hurt my feelings, if I left somthing out then please let me know, I just want to have a reliable set up nothing crazy, I will not be driving this car everyday it will be my weekend car so to speak lol.

thanks bro, I am probably gonna go with an aftermarket set to get the comp a little higher. I hate asking all these questions and bugging everybody but I just want it done right.

the thing is with a b20, the cylinder walls are 33% thinner, so with a high compression setup your margin for error is very slim my friend. i would suggest taking the time and effort into building the bottom end make it as bullet proof as possible. and yes have every thing balanced this will increase your rpm range in conjunction with upgrading your head components. and since this is a hybrid motor i would make sure to replace whatever parts i could afford with new ones just in case, bearings ect.
i have also heard that you need to get the timing belt that goes with the head. good luck bro.

#162397 well I guess I am gonna just end up breakin the bank on this one, I will get rods and pistons, hey do you guys think I should get a block guard. and I realy apreciate the info guys thank you very much. usually on other sites some blowjob would be busting my balls.

#162687 RS machine ITR pistons in 84mm would be what you want.

Only company to copy itr pistons in 84mm size.
By the honda guy
#162847 hey thanks man, I actually found this company (real street performance) on ebay that had a high comp piston and rod combo, so I emailed them asking if they could give me a deal on a package so the guy emailed me back and said this, srp high comp pistons 11.5:1 with the pins and rings, eagle rods with the arp rod bolts, cometic 84mm head gasket, arp head studs, and a golden eagle block guard shipped for 1050, so I went with that, so I will now be building a full motor. I actually am happier I had to go this route so I dont have to worry as much. As I get parts I will post the whole process on here, I allready have pics of my car as I stripped it down to nothing and had it sittin on a body jig, then pics of it at the body shop getting media blasted. So you guys will c it soon.
