If you read my last post I want to do a 3.8L Motor swap. But I need to see the Azera motor with the engine cover off and want to check out a few other things. Anyone who is willing to help me out here will be paid a few bucks for saving me the cost of renting one. Please email me if you can help. v33sonata@gmail.com
Thanks

5,000 orig miles.
You cant go wrong with my price, do your measurements with the enging on the floor!

I live in the Phoenix area...Surprise to be more specific. Have an '06 with the 3.8. You are more than welcome to come take a peek if you want. let me know.

Why would you want to swap for a heavier engine? Considering the 3.8 is only kicking out just over 20 more hp vs. the 3.3...would you really be gaining anything? Why not go for a supercharger???

I would wonder that too, especially with Hyundai's seemingly dubious suspension quality, how will the heavier engine affect the longevity or your shocks and springs, not to mention the balance of the car. Its already very front heavy with the 3.3.

:)

What about the additional torque? Remember the saying: There is no substitute for cubic inches. :grin:

What would make anyone think that the 3.8L engine is any heavier than the 3.3L? :wacko:

As far as "would you really be gaining anything" come on. Get real!
Have you ever driven an Azera GLS with a 3.3L?
If you had, you would already know the answer to that question! :P

And the Sonata is listed as being 171 pounds lighter than the Azera.

The horsepower difference is exactly 29 horsepower more, "not just over 20 more."
When we compare torque differences which is what most people view as the real power
difference, we find that the 3.8L motor has 263 ft/lb vs 232 ft/lb for the 3.3L.

Now stuff all of this into a lighter car and you might surprise a few folks at the bolevard grand prix! :w00t:

How much does a supercharger weigh?
Have you ever added one to an engine that was not designed for one? Well I have.
A really big mistake. :crying: Why?
The pistons could not stand the added pressures and blew. Very costly. :whistling:

:innocent:

I'm afraid I agree with Snag here... there's no replacement for displacement. My parents have a 3.3 in their Sonata. It's fine, not like it's balls slow, but the 3.8 just has some seriously nice torque. And - agree again about the supercharger - I would REALLY be weary about forced induction in a motor that isn't designed for it unless you get re-designed pistons and rings too.

The 3.8 makes another 29 horses and 31 ft-lbs. On top of the 3.3's numbers it marks around 12% on the horsepower and almost 14% on the torque. That's enough to be "really noticeable".

I can't seem to find specs for the 3.3's curb weight but I was under the impression that they used the same block, the 3.8 just had longer stroke and different head? Is that not correct? If it is then the difference in weight should be marginal at most.

Cool...I was just wondering.

He changed his mind about the 3.8 Swap, he is going to do it some other time now! It would be a good swap and worthwhile as the sonata is almost 120 lbs lighter then Azera and the 3.8 makes 265 HP vs 237 in the 3.3, and torque is 257 lb/ft for the azera while 228 lb/ft for Sonata which is a considerable difference.

That is why the azera although being heavier then the Sonata does 0-60 in around 6.1 sec and Sonata does it in 6.6 sec. Sonata's 1/4 mile is 15.1 @ 93 mph and although im not 100% sure I think the Azera is around 14.7 @ 98 mph in the 1.4 mile

This is true I have to wait for now. Sorry so long in getting back to you guys. the motors are the same weight. Its the same motor just diffrent bore and stroke! If ANY of you find a S/C that is made will fit on my car let me know I will buy it tomorrow........

Please, if you find a blower, DO NOT INSTALL IT!

Normal pistons cannot and will not stand the added pressures, and you will destroy your 3.3.
Even forged pistons sometimes will self destruct. All it takes is for
the motor to run lean for a nano-second and there she blows!

You might be able to 'get away with' up to only five pounds boast for a short while, but
it won't be long before your pistons with self-destruct and that can be very expensive.

Stick with your original idea of going with the factory 3.8L. Your lighter Sonata should fly!

Who will you get or do you know of anyone that can 'tune' your computer
to make the necessary 'corrections' to help pervent such problems?

I have much experience with trying to simply slap a supercharger on my new at the time Impala SS.
I didn't get 5K miles before I blew a piston. After going to a 383 cu in motor, I lost three more. (IMG:style_emoticons/default/crying.gif)
Finally set the Procharger aside and wound up with a 385 inch motor with 11 to 1 C/R and an
LT4 hot cam, and the heavy SS would run in the mid 13's at 104 MPH, but then
the trannies could not take that much power, and so forth. F E when to H...;
Dependability was less than poor and, well, I hope you get the general idea.

If i did do forced induction it would be very small amount of pressure. I altho thought of a 50 shot of nitrous. but well see. I will be using the Azera'S ECu so i wont have to do a tune right away.
