I have a b16a in a 91 hatch si and I wanted to put ITR pistons in it and CTR cams, with of course the valve train upgrades to support it. But my question how hard is it to put in these in. I have had quite a good amount of experience doing like four or so engine swaps and countless suspension and interior upgrades ( ie springs and struts to axles and hubs).I in no way am a pro so should I have someone else do this?

you need a shop to hone the pistons and press them in. cams you should be able to do with a manual and some net research (hybrid honda had a complete article on cam installation).

 

First of all you don't hone pistons you hone cylinder walls, and it doesn't require a machine shop all you need is a drill and cylinder honer, and a ring compressor($10 from kragen) to install pistons, I hone my own cylinder walls and install my own pistons in my garage...it's not that hard but I suggest getting a helms manual because there are certain steps and precautions that need to be taken when honing and pressing pistons in...but what you will need a machine shop to do is press the pistons on the rods because they require a press to get the wrist pin in and out. Oh and I am sure you know when removing the pistons don't mix up the rod caps keep them with the rod they came off of.

why do you need to hone the cyl. walls to use itr pistons? because im planning on getting itr pistons fitted to my ls rods and use em in my b18b. its alot of cheaper than buying forged. and i was planning on having a machinest fit em and press them onto the rod but installing them myself, but if i have to hone em. thanks

 

If you dont hone the walls the rings might not be able to seal.

 

I believe I have access to all the correct tools to do it, but my concern is do you guys think this would be something that could be done in a weekend? That is saying that I can get the machine shops to press the rods onto the pistons.

 

Yes you can do it in a weekend easy just make sure you have your rings most dealerships don't keep them in stock...and are you going to reuse your bearings? if not I sugget sizing them and ordering them before hand.

 

forgive my ignorance but the bearings????? I guess it's time to start reading my helms manual. If you could share some more of that knowledge it would be a get help, thanks all.

 

I will share my knowledge no problem...but when I am done drive your car down to a machine shop and let them do it...because if the bearings thing is causing so much confusion you are no where near ready to hone cylinders and install pistons.

Ok the piston is connected to a rod, wich is connected to the cranck, well between the rods and the crank is a thin piece of metal in two pieces wich put together make a circle they hold oil between the crank and rod to allow for lubrication...well depending on the size of the crank and the opening of the end of the rod different sized bearings are needed you need to take the pistons out and look at the color on the bearing...before I explain anything more you might want to just read a helms manual for personal knowledge but PLEASE do not attempt this project yourself, you will jack up this whole motor and turn it into a paperweight

Hmmm I was asking the right bearing to use, sorry for the misunderstanding. Now b18c, you can use ls rods? and the hammer thing, well I don't like the sound of that, so you have fun with your hammer. I do know what the bearing is and yes I mat be alittle ahead of myself, but thus far everything that has been done to my car I have done by asking and reading, so asking before I went forward with it. Hey b18c have you done thins to your pistons????? kawi thanks for the good input, you know I may be a novice but atleast I don't flaut the fact that I am an egotistical (for b18c), overly confident, person that is so bored that all you can do is make snide remarks that only insult your own intelligence. And how did you learn all that you know.......I bet you asked some questions huh????? I am not trying to be rude but I did read the helms manual and I was wonder what was the way someone else had done it.

Ok well the way you worded your question left me under the impression that you didn't even know what I was refering to when I said bearing...anyway like I said to get the size of the bearing the easiest way is to take the rod cap off pull out one half of the bearing and look at what color is painted on the side of the bearing...but do not mix the rod caps up they need to go back on the rod they came off of and not all bearings will be the same color so remember what cylinder number took what color bearing.

 

I pulled my posts because I am not going to get in a pissing contest with you. It's not worth it.

 

Yeah that is what I had read, hmmmm. Well Kawi did you do this install??? what rods did you use for these pistons, or what would you suggest????? thanks for the input and I think I have enough to try it now to get the materials together, and I do have a friend that has done all this before so he will be looking over my shoulder so I don't turn the engine into a paperweight. Hey b18c, no pissing contest just, post information man, I bet you know alot of good sh*t other could learn from too. thanks for the info

 

FYI, ITR pistons will lower your compression ratio slightly.

 

I had heard that so I guess going with CTR's instead would be the way to up compression???? guess that would make sense seeing as it is the wrong head for those pistons.

wrong head?
the heads are the same
CTR pistons are a good choice. jsut over 11:1

 

I used my stock GSR rods. Same as ITR's but not as strong or light.

 

Well is 330.00 with total seal ring set for CTR pistons a decent price? And how about 550.00 for CTR cams. am I getting ripped or are those decent prices

 

Decent price but total seal rings suck a$$, they are supposed to seal better...yeah my left n*t they seal better everyone I know that has used Total Seal rings has had blowby and burned oil, just use stock Honda rings. That is all I use in all the motors I build and not one problem yet. Oh if you are interested I have a set of Crower 62403a VTEC cams for sale for the same price you are paying for thos CTR's and the Crowers have more pull than CTR's email me directly if you are interested.

ummm he does need a shops help...keep in mind, you gotta basically take the motor apart to do this. also, he might not feel confortable with a hand full of extra "parts" left over if this is new.

 

A shop is only needed if you don't know what you are doing or don't feel comfortable with the project(which is what I think you are saying) but this is by no means a project you can't do yourself..like I said I have done it myself in my garage numurous times
