Putting a Vtec in a non Vtec

Hey I was just wondering how you'd go about installing a vtec in a non vtec motor. I've heard different stories from all sorts of people. I've got a 00 integra with a B18B1. I've heard there's kits for my motor and head but they're pricey. I've also heard I need GSR head, which new or redone is pricey but they are out there. Also I heard something about needing to modify the block, which sounds a little far fetched, but honestly I haven't a clue. Now what would be the best way to go about it? I'm looking for a little more performance and fuel economy without breaking the bank.
Thanks

I know of a few who did it on the old b series like the b20.

The common overview was it was very pricey and the gains werent worth it.

But this is on a family of motors that never came with vtec so not many OEM honda parts could be used without modification to do it. I think they ended up swapping to a newer b series head.

May be easier on your motor though.

Yea you can look into an LS vtec kit, but honestly, its not worth it.

You are better off boosting the LS (cast iron sleeves take boost well) and youll still have lower compression than a VTEC motor so you can run a bolt-on kit without touching any of the internals, although headgasket and head studs are usually recomended.

For around 1000 you can put together a frankenstein kit using parts from different cars and youll have worthy gains, and youll have more torque as well.

Thats the route I would go if I were you. I dont know what you mean by "breaking the bank". Tell us your budget so we can try to give you advice that isnt out of your reach.

Well as it is I've got over 1000 in the bank but with a newborn (the pic under my name is my 2mo old son) money comes and goes like the weather. I can tell you it wont be a quick job. Usually I'll get one part at a time and when I gather all the peices I'll put it together.
As far as doing the work myself, that's the route I'd be taking. I know enough to get by and do all my own maint. My job is a post-press mechanic, so I turn wrenches daily, but I cannot rightfully call myself an auto mechanic. Cars and trucks are just a hobby. Modifying the block sounds a little over my head so I'll have to look into it a little more before I rush into anything.
Now when you say 'boost' I assume you're talking turbo??? I've been told putting a turbo into something that didn't come with one was real project, but maybe what I heard including having the cylinders sleeved which would be something I'd bring to the local machine shop.
I think I need a little more detailed info before I decide on what to do. I do appreciate all the advice though.

You wouldnt need to resleeve your block, it already has Iron Sleeves.

What modifications do I need for the block then? Is it a machine shop job? Anything I'd do myself would be done in my driveway, I don't even have a garage where I'm living now, but do have access to one. Also I'd want it to be a one day job on account for a 30mi ride to work 6 days a week and my truck isn't too good on gas. Also I have access to a lathe and a bunch of other toys where I work but as far as removing the block, well I just don't have the time.
I guess what I'm really asking is how difficult and time consuming is this project. I've done a lot of work to this car, it's been my daily driver for years and whatever I do I want done right. With a newborn and all the OT I work, lately it seems there just isn't enough time in the day
Thank you very much for the help though. This has been something I've been considering for a while but never researched until now.

I've looked into it, and am considering it. I have a '90 LS. You need to obtain a vtec head and stick it on your non vtec block. You can get a b16 head or a gsr head, there's a few options out there. And yes you do have to modify the block. You also need a few other items, which you can buy in a kit.

I think whether its worth it depends on whether you can do the work yourself, and how cheaply you can obtain parts. Your fuel economy won't go up, and you'll have to use more expensive, higher octane gas.
