So I dropped off the block at the machine shop today. Also the crank to be fixed and balanced. Refer to this for pics of why it's going to the machine shop https://honda-tech.com/zero...age=4.

Im open to a few options and wanted to see what would be the best way to go about it.

1. oem girdle
2. aftermarket 3 point girdle
3. 5 point girdle
4. have girdle made at machine shop

I really like the idea of the 5 point girdle but the price is kind of out there.

The engine is there for line bore, having main studs installed and getting bored. I figured now is the time to add a girdle since I'm having the line bore done also. Is the oem girdle a worthy upgrade?

Thoughts...

I'd throw that crank in a dumpster before i paid to have it repaired. Turned honda cranks almost always lead to problems. Find a good stock crank and use it.

On the line bore, make sure the machine shop understands that the crank centerline CAN NOT be moved or you will have oil pump problems..

Ok, I'll get the crank from him that I sold to him a long time ago. He also has a stock stroke eagle crank but I see no need for that. Wasn't aware that after turning they became a problem.

I explained to him about the crank centerline needing to stay where it is. His response was it should stay where it is at unless the line bore is off enough right now that it would require more than .002" removed from the block side of the mains, and if that was the case he said he would recommend scraping the block.

He asked how much power I was looking to make. I told him probably 700whp or more. He looked at me and smiled kind of weird and said that since I was getting it line bored I could even go with Billet main caps, He must think I have lots of money to spend. I told him to check on how much they are and let me know.

I just think it would be a good idea to add a girdle at this point, needed? maybe no but is it going to hurt? no.

Thoughts on balancing a stock uncut honda crank?

I have balanced Honda cranks on a few different balancers and they are real close from the factory.Personally I would not pay anyone the balance one for me.I would find another shop with experience with Honda blocks/caps.They are a bitch to do correctly.I would not use a reground Honda crank or an Eagle crank.I'm also not all that hot on girdles.Done correctly they will not hurt anything but most of the loads on the caps are vertically and I don't see a girdle helping that any.

Billet mains, huh? I'd find a machine shop with some honda experience...

sounds like the machine shop is iffy at best. you are in the ne, send your stuff to jj and be done with it.

yep.

im sorry but there are more than one machine shop more than capable of machining the block. expletive the hype

Of course there is, but it's nice to deal with someone with some honda experience, and if this guy is recommending billet main caps for 700hp, he obviously has no honda experience. As sensitive as these blocks are to any crank/main work, if it's not 100% it's going to lead to a lot of oil pump problems.

Just to shut some people up, this guy knows what he is doing. He doesn't do honda only engines like some shops do, so he just said about putting them in. He didn't say you should do this or you should do that.

I'm not giving him the engine and telling him I want this much power do what ever you think it needs and let me know. He is doing what I tell him to. He does alot of different things for different types of racing and actually does a good bit of work for other shops that can't actually build engines.

The fastest 4cyl engine that he has built is in a ford probe, rwd, 7.60's 1/4.

Either way, I trust his work 100% I just need to know what I should have done and if adding the girdle will be worth it.

DaveF

do an aftermarket 3 main and be done with it. put main studs in it too.

^^^ truth!

yea your crank looks absolutely horrible. find a new one.

exospeed went through alot of cranks before they finally found a good one for my engine. very important.

Thanks Dave, thats the response i wanted.

New crank, aftermarket girdle, line bore, cylinder bore/hone, other new parts, try again.

Any recomendations on an aftermarket girdle to get or stay away from?

DaveF

we use the z10 girdle/aebs main studs on steves car, on my car there is an oem gsr girdle/oem main bolts, just because thats what i had, and didnt have $ to upgrade it. GE main girdles look nice too, but i havent used one of theirs yet. i like the z10 girdle because you can dowl it, but i dont think that is 100% neccessary. z10's also has some machining done to it, that i dont think other girdles have.

Is there much difference between an oem girdle (new) and an aftermarket one? How good do the oem girdles work?

Anyone know the best place to pick up a girdle, like vendors or people on here. I keep coming up with some KMS when i search for girdles.

tony1

I run and oem gsr girdle and oem main bolts in my race car.

80884

wow, ok, that makes two cars that I know of that make lots of power and like to rev running the oem. Maybe I'll just get the oem one and be done.
