i know its been done but who hear has done it, and how long did it last?

nerdsports

also interested in seeing some responses.

bad idea...
First of all you should always have machine work done on the block to make sure the cylinders are perfectly round, this cant be done in the car.

Second, it doesnt take long at all to pull a honda motor. Compare that to trying to do all the measuring and correct proceedures for building the engine with it in the car, and your only wasting time.

If you dont pull the motor out, you will only be cutting corners durring assembly, which will garuntee you a bad motor in the end. Why spend all that money on internal engine parts only to half *** the install job?

Building the block in the car shouldnt even be an option.

I agree with ironlung. Building a block should require you to take it out and send it to a machine shop.

It would be hard to install ANYTHING, much less to make sure your clearances are precise when the motor is bolted in place and unable to move.

I really don't even think there is a possibility that a machinist would bore and hone your block either. It would be a discrace to the machnist to put such an inevitably terrible quality of machining into a block.

i know guys drop rods/pistons with the block inplace. not ideal, but ive seen it done.

turbotime

my buddy dropped the pistons and rods in the car with the engine still in it. Made 400whp, then sold the car, still running strong hes had it boosted like 3years or so....

not ideal but it does work.

richeybrooks

thank you. anyone have bad expenences with it.
i think i am going to do it with a little dvd help.

IRONlung201

Dude, dont do it...
Your talking about building a motor the most half assed way possible, AND watching a DVD for instruction. You obviously have no experience in engine building, Im sure the poepl hwo have posted they they did it had some engine building under their belts. Your gonnabe doing nothing but wasting time and money when it doesnt turn out right.

Maybe your not aware of what putting togethor a motor RIGHT involves.
Check this link out, and then tell me you want to try and do this for your first time without puling the motor...

again, VERY VERY BAD IDEA

yeah idk if id do it with NO experience and using a dvd but it can be done, it isnt that hard, and it isnt doomed to fail.

see your issue isnt so much building the engine in the car as knowing how to/what to do in building an engine...

btw evans is who tuned my buddies 400whp built-in-car engine, like i said still runnin strong

Building in car is for an engine that weared very well, and didnt need ANY maching or honing. If you know the history very well, and you know how to build a motor, then replacing pistons and rods in car can be done, without being too awkward.

I think the dvd thing is a little scary

It depends on the current shape of the motor. When you take the head off and the walls are still in good shape with hone marks still present then it will be fine. Not ideal, but it would work nonetheless.

You also need to look at the rods bearings. If they are worn really bad then you can bet that the main bearings are gone as well. Then the motor need to come out.

I agree with what you said except for this. But it did make me laugh at work. Just for future reference. Your cylinders are not perfectly round. They are egg shaped.

IRONlung201

I understand that they are not PERFECTLY round, maybe my choice of words was wrong. Typical maximum allowable out-of-roundness is about .0015" i believe (not sure exactly on honda specs). My statement was meant to emphasize that I believe it is best to always bore the cylinders when installing new pistons, .5mm at least depending on the condition of the cylinders to begin with. This will insure the best possible starting platform for ring seal and overal performance and longevity of the motor.

just take the damn thing out, doesn't take long at all man!!!!!!!

It would be more of a pain in the *** to work around the car and under the motor instead of just taking the motor out.

ramennoodles

I did it on my ls motor. removed pistons and rods. honed with a hand drill. dropped new pistons, rings, rods and rod bearings in. I've put a few thousand miles on it already boosting 15psi street/26psi track. almost no blowby at all either.

richeybrooks

1. im not a HT dumbass! ive built 3 motors before by taking the block out and blueprinting it exe.

2. i know how to do it.

3. if you dont have real experence i would rather you not post.

4. From what i understand many people that have done it this way have had good experences. Others that just read forms and have never even seen a forged piston say dont do it.

5. im doing it and ill do a writeup on it.

I'll be looking forward to this.

TheThiefTheKnife'NTheGun

Its so easy to take a honda motor out it would be far less work to just pull it.
I did it on a 4g63 dsm motor it worked but like others said its not ideal.

IRONlung201

Seems as though your dead set on doing it, so good luck

May I just ask one question... what reason could you possibly have for not wanting to pull a motor that is so damn easy to remove?

btw dont try to pass off other's opinions on the topic that you asked about by saying they dont have experience, just because they werent giving you the answer you were looking for... thats just retarded. IMO, if this is your 4th engine build and youve done this all before I think you would know the importance of precision and thoroughness involved in this sort of thing, and I just dont see how this can be achieved they way you want to do it.

I really dont understand how pulling the motor is such a problem, if anything I feel like it will save you time...

But again, do you, I wish you luck in your build, and if it turns out good, then to you.

sc4dr

If you've built 3 motors before, why would you ask about building one in the car? The process is the same as far as assembly of internals, its just more awkward.

I think everyone thought you had no experience the way you were talking....so dont get pissy

built 3 motors huh? then you should know whats good..and whats the deal with a dvd? you need a workshop manual,and tools,,not a dvd,,some one who's built 3 motors should know that
