Just Wondering how hard it was to put pistons and rods in my motor I have a d15b waiting to be turboed but I want to put cp pistons and h beam rods in to make more power but i was just wondering could I do this myself how hard is it?

not hard at all, but if you don't have that much experience under the hood, then i don't suggest it. and the fact that you have to ask tells me that you shouldn't do it.

Pretty well summarized.

 

Its not hard, but you have to do everything perfect. If you mess something up there you can kiss your motor and all the money you just spent good bye.

 

i just pay someone to do it cause i dont have the neccesary tools to assemble a shortblock. a lot of things you need to measure

 

if your unsure.. and havent tackled anything like this before.. Id just have a shop do it, either way, best of luck

Either that or if you don't care much about the engine - DO IT.

Great learning experience. One of two outcomes. A) You'll do it right, or B) You'll do it wrong.

I'm not really sure how you could expletive it up but I suppose anything is possible.

Though it sounds (by you stating that you want to make more power out of it) that you care about this motor so it may not be the best.

Though if you really wanna learn just buy a **** motor and swap the pistons out and see how it runs. Everybody keeps talking about "if you've never done this before etc. etc. etc." but with engines you will "have never done this before" until you actually do it - and until you actually take the chance and step out on the ledge to do it, you'll just be pulling your pud asking yourself the question of if you can do it or not.

 

putting it in: both is easy. checking clearences at the rod bearings and main bearings, boring out the block so it's within factory specs, decking the block, and milling the head to factory specs is the harder part. milling and bore the block is best reserved for the machine shop to deal with. and the head too.

Not meant for the weekend shade tree mechanics.

So to answer your question.... yeah it's easy putting in the pistons and rods.

 

I have worked on my motor before I use to have a b16a crx back in the day but for right now all I have is a d15b about to be turbo for now. The thing is all I have ever done was externall stuff like intake mantifold swap header swap all that nothing like internal yet. But I really wish I knew how to do it. You just have to get everything right thats what I am afraid of.

whats the worst that can happen? Spin a bearing?

How can u mess it up?

 

Time-honored rule:

If you have to ask how, then you can't.

 

Possible he doesnt put in the rings right?Shouldnt be that hard but if you dont have the tools dont do it.And if you hve to ask then you cant do it.Its a rule of thumb.You can try and maybe succeed. BUt odds are youll fail miserably!lol.Just go to a mechanic and tell them to put it in while you watch.Maybe youll be able to do it after.

Spun bearings destory cranks, Bad gapping can destroy cylinder walls and pistons. Bad torquing can destroy everything all together.

Asking to do something is perfectly fine since you want to know, what i recommend is picking up a helms and saving 50-100 dollars on propper good tools (ring compressor/expanders, ring filer, torque wrench, plastigauge, feeler gauge) Dont buy cheap (craftsman should be the lowest on your list). When your tearing down the motor notice where everything goes and how they go. In your CP box they should have a paper where they want you to put the rings and where you should gap them to. Follow those to the T, also grease up your bearings accordingly, dont over do it and dont under do it. Theres alot of info out there. Heres a few for you to get started:

That should keep you busy for a while.

 

seems like everyone who is trying to tell u you'll fail if u do it cant/or hasnt tried to do anything on their own.

Give it a shot, take ur time and it will all go good! Have a little faith in urself. Everything Ive done, i didnt have a clue how to do it. U learn from experience, not people telling u not to.

 

i actually purchased on ebay a video of a guy pulling apart and putting back together a d series motor.Didn't look to hard just need a mnaual for clearance and all, but i say get a **** motor pull it apart and put it together.You will never learn unless you try.

Are you serious. I have seen people ring the piston incorrectly. **** I have seen people put the pistons in backwards. There are so many things that can go wrong. It is possible to do yourself, but not recommended if you drop a a bunch of money into the motor. If you want try practicing on a crappy motor.

 

im working on a friends big block v-8 at school, theres lots of measuring involved, but thats were you learn it, Auto Class! my favorite class in school! lol

 

its harder but easier than you think it is...that just about sums it up.

 

Engine building is not that hard. Just remember that everything has to fit within some pretty tight tolerances. If you have never done it, or seen it done, do not trust a book to get you through it. Dont get me wrong, the book will have all the correct info, but your particular translation of that info may give you a less than desirable outcome. Have the shop build it, or watch a trusted and experienced friend do it. By the way, in order to fit h-beams in a d series you will have to notch the block. (at the bottom of the sleeves) Good luck with what ever you decide to do!

 

I think what i am going to do is get a back up motor like a donor motor and take it apart and do things very slow because right now since I dont know what Iam doing I really cant loose my job for something stupid like trying to make power when I dont know how to do internall stuff. But thats y i want a spare motor to learn and find out what I am doing.

Just what I was going to suggest.

I've never done it but I wouldn't hesitate to try, given the opportunity. Just make sure to read, read, read, and read some more. How else are you going to learn?

Let us know how it goes.

if you have the money, then it's all good.

i'm the type of person that has to have hands on. i can't learn by watching, buying a spare motor and building that one would be the best. pick up a d-series motor, just because they are cheap and easier to come by.

 

I plan on grabbing a junked D series, just to try and pull it apart and rebuild it, try to put in as little $ as possible, just tos ee if I can get it together and running.

ATM I do the same with body work, I have no real experience with shaving door handles, spot welding out rust holes, or adding sheet metal to body panels. I go to the junkyard every so often, and ask if they have just some junk hoods or fenders and doors. Rusted dented, whatever....

I bring that **** home, and work on it, and if I expletive it up, owell 10$ hood : /

JUst grab a 100$ D-Block, and rip that **** apart and get dirty...
