aight, right now im runnin a 1.6 sohc vtec...and its blowing some oil, not a whole lot, but when i get on it you do smell some oil...i think its a good possibility that it could be my piston rings, but im not sure...i was thinking about ditching the motor and going with like a b18a or something, but not sure yet...my first question is, how hard would it be for me to replace the piston rings, and build some of the internals so i can run like 8 lbs of boost...my goal is to run some kind of turbo, without having to swap the motor....would you do this on a motor that is burning oil, or would you just wait until you get a swap for it...im trying to keep the costs of all this down bc i dont make THAT much i cant afford a whole new motor and then turbo on top of it...what would need to be replaced to my 1.6 to 1) make it not burn oil anymore and 2) capable of running about 8 lbs of boost without any harm to internals...

help me if you cannn

in my opinion, its easier to replace those piston rings than swap into a B18. and as for internal work there's not not going to be much you have to do if you're going to only do something running 8lbs. whaty i would do is while you hhave that engine out, get a whole new set of the JE turbo pistons and new eagle connecting rods. that would be faster, cheaper, and easier. cause swapping motors does tend to take a bit out of your day. becuase when you do a big swap like that you end up nearly stripping the whole damn thing. just take out that 1.6 you have there and work with it there, but also this is just my opinion.

how hard of a job would it be for me to replace the rods and pistons? thanks for your opinion i as well do agree lol

if you want a B18A, theyre not TOO hard to come by, and not extremely pricey, and boost friendly if you wanted to turbo it down the road

well i do want b18, but at the same time if i could save all the time and money on swapping i would prefer to turbo the d16z6, and change the rods and pistons...

hey whatever you want, its your decision, good luck with the build
oh yeah, with those internal changes, you can run like 15lbs of boost, some guy ran 16.5lbs on a bone stock D16Z6, but that probably wasnt too smart, just run 12psi

crower rods $300, vitara pistons $100 and rings, about another $75 and a few other things(gaskets and so forth) $200. = cheaper than a B18

read the vitara articles...

you can run 8psi with good tuning on your stock motor.

you should be able to run 10psi on the mentioned above!

also the mentioned above will cost you a few more dollars than mentioned, but in the end you will spend about the same for a STOCK B series.

you weigh out your options...

you will be much happier with that set-up than any B series set-up. check out http://www.homemadeturbo.com

depends which b18, a b18b is a hell of a lot more costly than a b18a, i thought thats what you said you wanted earlier, but yes, a turbo d16 is a LOT cheaper than a b18b, and more powerful too

stew18564

yea but the problem is that with my busy schedule it will be hard for me to find time to install the pistons and crower rods and ****....how much you think it would cost me for a shop to do it?

stew18564

anyone???

no clue on the price, do some research and talk to some people, you could always just do it yourself

Building an engine isn't nearly as easy as an engine swap.

Pretty much anyone with common sense and a basic toolset can do an engine swap if he/she is mechanically inclined, and they can usually do so without a set of instructions.

Building an engine requires a different skillset altogether. You need specialized tools (Ring cutting tool or file, ring compressor for installing pistons, etc.) and you must have detailed ACCURATE instructions as well with correct torque specs, etc.

You also have to rely on other people, such as your local machine shop, and hope they don't **** your **** up. You also have to reply on your parts supplier too, whcih again requires a good bit of trust.

I'd say at least half of the engine builds I've seen with forged internals smoke. Call it shoddy building if you will, but some of the builders are very skilled mechanics that have built engines before. I think it has much to do with the parts, machine work, etc.

I have built a D16A6 for myself and I guess I got lucky because it never smokes at all, but I also used brand new OE Honda parts.

As far as building a SOHC for boost there is NO reason to lower the compression from the already low 9.2:1. In fact if I were building a SOHC for boost I'd raise the CR slightly to 9.5:1 or maybe even 10:1 depending on how much boost I wanted to run.

Lower CR = more boost lag, and the SOHC will already have a tougher time spooling the turbo without some stupid-low CR (8.5:1 such as those Vitara pistons) so I'd go no lower than 9.5:1.

The swap?

That's your call. It definately more fool-proof and can be done in one day without having to send **** out to be machined, waiting on little unexpected parts (if you do your reseach thoroughly and don't start without all your stuff), and waiting to borrow specialized tools.

Bottom line?

A boosted SOHC can and will make more whp and torque than a B18B swap, and it can do so quite easily. Normally I'd say it can do it stock, but if you're already burning oil you need a rebuild. The B18B if low enough miles will also be able to take boost and easily decimate the SOHC boosted number and torque.

My 2 cents.

I'm sorry I just have to reply here.

How do you know he will be happier with a boosted SOHC over ANY B series set-up?

I hate to be a dick, but that's a pretty vague statement. I have to say from personal experience that I'm happier with my B18C5 swap than I'd be with any boosted SOHC or even boosted B series set-up because I personally like being able to drive my car as hard as I like for 4 years without incident. Also the power delivery of a boosted car is totally different, and sometimes unpredictable, when compared to N/A motors. If you are big on twisty roads, auto-X, or especially open track days then boosted Hondas are NOT what you want. If all you care about is blowing off at people and being Billy Streetracer, then go for the boost.

Boost will not last as long as a stock or mild N/A build-up - PERIOD.

If you like tinkering with your car a lot then you might draw more satisfaction from boosting a SOHC, but if you're like me and you want 100% factory reliability, then you might want to save up more money and get a B-series VTEC set-up that you can run with no worries for years on end.
