I have a 15' SXL Sorento. I've been looking around online quite a bit since I purchased the vehicle back in July 2014. Not coming up with much aside from floor mats, lighting, etc. Was wondering if anyone has come across any other aftermarket parts for the 15 sorento 3.3l ? I see that there's talk of hyundai 3.3L with a TURBO. Maybe we will see a turbo kit for the sorento...doubtfull.

Thanks

Not too many people looking to hot-rod their Sorentos. They're good just the way they are. No demand, no market. Besides, with the long warranty KIA gives with their vehicles, and the fact that anything other than OEM parts would invalidate that warranty, people aren't so likely to give that up.

I'm also wanting to upgrade my SX - but after driving a 2016, I don't think I'd ever be happy. The improvement in "pick-up" on the new model is significant. I wish I could have waited to buy my 2015, but my totaled 2011 had to be replaced.

I would like - better brakes, slightly stiffer suspension, and better throttle response. The 2016 has the last two.

Coming from a '12 SX, in my opinion, I think it only has the first one you mentioned. The moment I test drove the '15 SX I immediately noticed the stronger brakes on them. The better throttle response, I'd say if you keep the Eco mode on, you'd be getting less on the '15. But I keep them off all the time and it revs higher in the rpm range before it upshifts compared to the '12 MY.

Brakes on my 2015 are slightly better than my 2011, agreed. Could be so much better, though.

By "pick up" I mean getting the car moving from a standstill or accelerating suddenly when needed. My daughter's (v6) challenger seems to get going so effortlessly (very similar power/torque numbers and weight) - and the 2016 Sorento felt very similar. Given the fact that it's a mid-size SUV and not a "sports car:, it's not surprising that the Sorento doesn't lurch off the line or pull hard the instant you give it more throttle. They have, however, improved this significantly in the 2016 model.

Use ECO to switch from "normal" to sport. Better yet, tie throttle response to the steering modes (comfort, normal or sport).

Going back to suspension, I loved how the 2011 drove. The 2015 is fantastic in comparison, but the 2016 is better yet.

I know this is all a pipe dream. I think I should buy a Jeep SRT8 and leave the Sorento unmolested.. :)

I don't know, but, I can break all tires free on a bit of gravel they spread on my community roads between storms up here, usually it's even by accident, when I take off. With The low, low, 1st & 2nd gears, mine takes off like it's shot out of a cannon! I've surprised a lot of vehicles between traffic lights, sometimes even smaller "fart cars"! Maybe you need a new "Wicks" air filter? And, or, "To do the pipe thru the resonator trick" My Sori still seems louder & faster since I did both! Even though I took the pipe back out after a coupla days, months ago. Remember I did each one, at separate times, with the engine warmed up, and right onto the Freeway, to go though the gears and reset the O2 sensors, & ECM I definitely lost a few mpg's. But, I also use "Sport" mode most of the time, until I need to save gas, then into ECO mode.
That Beautiful SR-8 will probably eat even more gas though :(

I'm not saying it's slow once it's moving, but there is a definite lag between advancing the throttle and the vehicle responding.

Since my post above, I put on new tires - MICHELIN PREMIER LTX 235/55R19 101H BSW ALL SEASON - very happy with them. My 2011 I put on Toyos and was not happy at all. These are better than the OEM tires by a good margin.

Ok, I'll give you that, when riding along over the many hills, & curves up here, on occasion I've noticed a slight lag in the throttle, (like a dead spot?) on acceleration. It's annoying to have to push down the pedal more then you should! Because the next thing you know, it's downshifting, and you're going faster then intended! :eek: I wish that somebody would understand this issue, and fix it :( My EX has 235/60/18" but I'm on the lookout for a good 55 series, I'll check them out, thanks!

Electronic throttle are just that: they are programmed..to the idea of the programmer. It then would need a change in the program. I do not know of a utility that could open the code...and let anyone change it.

There are "chips" that would alter the programming, but probably not for our car - as covered before, no demand..

When my Sorento was new, and for the 1st few thousand miles, I had to be very careful stepping on the gas pedal, it responded immediately! I usually let my girlfriend drive, because she didn't push it hard, like I would. I needed to get used to the vehicle. Then, over time till the present, it started with that "Flat spot" on acceleration, sometimes not responding till I am 1/2 way down on the pedal! Then suddenly automatically dropping into "passing gear!" At the Wrong time! on a hill, or in a curve! Instead of just responding to minor throttle variations!

I've tweaked the engine for more power with the new (seems less restrictive) Wicks air filter, and "Resonator pipe bypass trick" to actually get it to deliver more sound, & power, at the expense of gas mileage, but the "Flat spot" is still there! :( When I brought it to the dealer for regular service, & an oil change, and mentioned this issue, they blew it off, saying they couldn't find anything Wrong?

This really bugs me, because I don't live on flat Long Island any more!

In fact, I used to have someone hold the throttle full open inside while off, & check the under hood Accelerator linkage on all my cars, to make sure it was fully Open!
Now, I can't even do that! Damn computers! :mad:

I know, the lack of Performance parts, The 1st thing I usually do is get a K&N low restriction air filter. If you have a vehicle that's running okay! I've been holding off on this because of the acceleration "flat spot" issues! So for the time being I picked up a Wix filter, which seems to be less restrictive then stock IMO. Next, I usually get a low restriction muffler, no "Cherry Bomb's", been there, done that, on a New 69' Charger R/T 440 auto. :eek: But, something like a Flowmaster 40, or Flow Delta 40 series, the Delta has less drone. These items will boost your performance. I used to jet out my carbs, and add stainless core suppression plug wires, a performance coil, & distributor cap, then set up the timing a bit advanced, & run high test gas. I also discovered IMO, over the yrs, with synthetic oil there's less friction, more power, it runs cooler, and your engine runs smoother. Also, I found there's a bit more protection in an engine mishap, like overheating, or whatever? Good Luck!

Mike, sounds like you need to go to another dealer to get another opinion. They should be able to run a diagnostic on the throttle pedal and make sure it is operating correctly and not flat-spotting and/or make sure the software is up to date.

Making substantial intake and/or exhaust changes on these vehicles isn't as easy or effective as older cars due to the myriad of sensors and computer integration that to my knowledge, can't be modified by the end user. I don't think any sort of Hypertech or equivalent aftermarket chip/programmer exists for these vehicles either.

Without extensive modified or the use of an aftermarket EFI system, that I'm not even sure is possible, most "mods" to these engines seem to be more superficial than anything else. Of course you can experiment with different filters, spark plugs and maybe even a DIY cold-air kit, but I wouldn't expect much in the way of gains.

There are big-brake kits and some suspension upgrades from Korean auto parts importers, but I haven't seen much else that would more substantially improve the engine performance. Maybe something is available to the Korean domestic market, but so haven't seen anything here in the USA.

If you wanted more performance upgrade options, going with a Jeep Grand Cherokee would have been a better bet since the Jeep's have a much more diverse and deep aftermarket.

Whats the resonator pipe bypass trick? Would this be the same for the 17 3.3?

Sorry I temp. forgot my login code! I picked up a "Resonator" eliminator pipe apprx 2' long x 2-1/8" o.d. snug fit, stuck it into the exhaust tip till the flared end was in the exhaust tip. Took it out for a ride, & All I go was more Drone, no rap/pulse like I wanted. But, the Sori got noticebly faster! Didn't like the sound, so took it out, but surprisingly the Sori stayed a bit faster for awhile afterward!

Since then I have put a new Flowmaster Delta 50 muffler in it's place! It has a mild motorboat sound now, and is a bit faster as well!

I recently pulled the AWD fuse on my car, and it scared the bejusus out of me, powering fast up from a dead stop, front wheels spinning, lost all traction momentarily! :eek: It's back in place now!

H&R makes lowering springs

Luxon makes suspension/handling upgrades: sway bars, strut tower brace and chassis braces - see them on ebay

I sorta upgraded my brakes using BrakeMotive's full brake kit. It's just ceramic pads and drilled/slotted factory size rotors. $160 for the full front/rear kit.

Lately, I'm trying to figure out how I want to go about finishing my audio upgrade.
