Anyone else have any comments?

:wontshare:

I really don't like the idea of ball honing motors in car.
I REALLY REALLY do not like the idea of half assing a motor build.

But if someone is on an extreme budget, I have seen it done, with scattered results.

Like what? I know this isn't an ideal, stage 5, 8-second, bulletproof motor build, but bear with me. These tech threads are quiet and I *know* there are people here with experience here. If you have actual examples, please share!

I may not consider this myself, but other veterans have testified that this is a great way to add some insurance to your bottom end w/o going through a full motor build.

I have to say though, for someone like me, it's a pretty attractive option! This would open up the window to safely run a big turbo on my DD car w/o the hassle of pulling the motor and dealing with the hassle of several weeks of downtime while the motor is being disassembled, on it's way to the machine shop, at the machine shop, coming back from the machine shop, waiting on assembly, etc.


Think of it, a one or two-day job instead of weeks of downtime in a traditional motor build. Sure it it wouldn't be built to rev out to 10k rpms, but hey I'd have something stronger than the factory stuff and the wife would buy it if I told her that the car was in for a timing belt job :)

Well it does have its pro's and cons.
It is cheaper than a full build and does involve less downtime..unfortunally with just a ball-hone you will be hard pressed to get the optimum surface finish on the cylinder walls, not that most shops even care about that.

I mean it does have its pro's and con's, I just feel weird towards the thought of doing something like that. It will allow someone to do it on the cheap, and the added insurance is much better than the factory stuff.

I think that it's doable in a day. But like you're already thinking, it's not a bullet proof motor.

Honing is very very messy. I would be most worried about the dirty, metal filled goo that is created when you hone. It's probably the last thing you would want in your motor. You need to somehow try to keep the honing residue from seeping down the cylinders onto the crank and into the crank case. You also have to try to avoid the oil squirters with the hone, unless you remove them. With a 1G or 2G, it is easy to pull the motor and you could still avoid removing the crank and oil pump assembly, but flip the motor upsidedown while you hone it. Pulling the motor on an Evo on the other hand does suck. If you wanted to try to do it with the motor in the car, I would try stuffing some rags around the crank, then cut a stock piston apart, leaving the rings, then inserting the piston back into the hole that you are going to hone upside down. Put some heavy oil around the edge of the piston and hope the rings stop most of the gunk from running down. I don't know if using a pistons in that way is feasible with the Evo though. The pistons rings might not be close enough to the crown, because it's a turbo piston or the whole thing might be too tall and end up keeping you from reaching the entire length of the cylinder wall that the rings contact.

I know it's late but I did this with a minivan, I know it's not really performace minded but I did it in the driveway. I just made sure all the surfaces were really clean after and continued on check and rechecking bearing clearance. I had it done in about 6 hours work time. To add to ecoli's idea what if you just used a top ring wit ha bead of silicon arond to make a small reservior to catch that crap. That van has put 40,000 on since then and still running strong.

Bump, just found an interesting article on this here:

Also, Buschur has boasted doing this on his bro's car with 50k miles on the stock bottom end. If I'm not mistaken, this is the same bro and same car that ran a 9.7 1320 on a BBT67...

The cross hatch looks realy shallow on the pics posted. There is more then one way to skin a cat, but I would not do a motor build that way.

In my opinion, this seems like a fairly half-assed way of doing a built motor and is just asking for premature failure.

But then again you can have failures on new fully build motors. Slowhites motor was fairly new(I think) and It blow up (oil problem I think again) Nashs new motor popped. So fully build or half assed rebuild there all dsms in the end.
