So I paid off the car recently 2018 ES with 43k miles ( I'm the original owner), was looking at a g70 or Kia Stinger brand new but my wife wants a brand new Sienna so I figured it was more responsible to put 7 to 8 grand into my car to make it drive the way I want and keep it for another four to five years.

I started with a lower motor mount, dual catch can (sxth), and the bov solenoid upgrade (Pierburg). Had my down pipe (sxth) in for about 1 week, upgraded the plugs hksm45xl, intercooler with hot pipe upgrade (sxth), takeda momentum intake put in 2 days ago, have a EK1 lite for remote tuning. Things coming this week, pierce axleback exhaust, ebcs (pierburg, rear sway bar ( pierce), rear sway bar endlinks (white line), bov
Go Fast Bits t9221 hybrid dual oulet valve, n75 neodymium magnetic drain plug, X1-Revolution OBD2 Multi Display Engine Monitor, Powerflex Trans Mount Bushing Insert - Race (Black), Powerflex Upper Motor Mount Bushing Insert - Race (Black), MSD High Performance Ignition Coil Pack, 1.6T DCT Custom Hybrid K03 Turbo Upgrade Kit n75, ECU/TCU tuning n75.

Here are some photos of the down pipe install, intercooler, and intake.

P.S.

If you buy a sxth intercooler for the 17-18 Elantra sport they say that there's some light grinding required to the crash bar. Make no mistake about it, it's not light grinding, you have to cut the bottom of the crash bar to get it to fit.

Shout out to my man Joe he's the guy blow torching the mid pipe to the cat, he went to war on that down pipe install he is the mechanic at my dealership. We actually broke the stud taking off the cat, there is a security nut on the turbo that doesn't like it when you try to take it off.

It's like Christmas, so many packages today, hopefully I'll get the axleback exhaust, ebcs, and the bov on today. I'll attach the velossa big mouth later. Read my ECU last night after updating the firmware on the ek1, sent the ecu data to n75, ecu/tcu custom tune coming shortly!

Axleback installed, if your in Columbus Ohio nobody better than Mad Hatter for your exhaust needs (shout out to Donnie and Tommy!). They made sure my bumper did not melt and got the tips lowered. Sounds good, gonna hook up the ebcs and use the ek1 to write the tune to my ECU.

Got a borescope to check intake valves, been running amsoil 5w30 until I got tuned now I run Redline 5w40 with ceratec liquid moly, going to rotate with liquid moly molygen/ceratec and redline. Would stay with amsoil but they don't make a 5w40 compatible with our car. Here some photos of the valve from chambers 1-2 ( I have video of chamber3 was pretty clean like 2, 1 had more carbon, and 4, I didnt get to). I run crc intake valve cleaning every 10k miles, no oil catch can until about 5k miles ago. I'm quite happy with the results ( amsoil, top tier fuel, and crc). Snow WMI with trunk upgrade,, and KDM tuners TB spacer ordered, so carbon is going to be a thing of the past.

White line performance lower ball joints front control arm bushings, and lower control arm bushing arrived today also. still waiting on the Gecko coil overs. Once they get here all will be installed.

Got the rear sway bar from Pierce motorsports and white line endlinks installed last friday. Cornering like a champ, can't wait to see what the coil overs and bushings do. installing the Whiteline transmission bushing tomorrow. Strut bar is next purchase.

Installed my velossa big mouth, and switched my takeda momentum filter to the oiled one, gained 2.5 psi. I would max out at 20 psi before. Exciting times, stuffed turbo on the way, and coil overs. Debating about head studs and valve springs.

Head studs not necessary. Either are the springs unless you want more revs. Curious with all this money spent on the car why you went with Gecko coilovers? So many other, better options.

So over 300 whp I wouldn't need headstuds ( I know it says 280 whp but I'll hit 300 +)?

They came highly recommended for daily driving and some autocross here and there. What would you suggest? Got them for $864.

SXTH's shop car made 400+ whp on the stock head studs. The only version of this engine that studs would be recommended were the 1st generation Veloster's.

For coilovers, Yellowspeed Racing would be my recommendation, followed by BC Racing. Both more expensive but suspension is not something you want to cheap out on.
I saw the video of the sxth car he didn't really put his foot down because he didn't want to be the one to blow the motor, lol. I got the point though, I think they got 90k miles on that car before they sold it.

I found these on their site,


It's only 400 more what makes them better?
