I just bought my Genesis (2.0T) and would like to hear some suggestions for the first thing to modify on this car. I am new to the whole tuning scene, but I am not afraid of picking p a wrench and getting my hands dirty. Where should I start with my new ride?

 

Manual boost controller set at 17.5 psi. AMS saw 45 whp in the midrange from this mod alone on an otherwise stock car.

 

Well, from what I've read you need to get a BOV replacement solution (from Buschur Racing, AMS Performance, or Beyond Redline or maybe others) and a manual boost controller from Buschur Racing or elsewhere.

 

Oh, and when you install the MBC, don't cut the factory hoses. Use new hoses. This way, you can remove the MBC and re-install the factory hoses if you ever have a warranty issue.

 

Thanks guys! I found the MBC on Buschur Racing, but the only BOV replacement I have seen was on genesisspeed.com. Am I completely missing something on the other sites you mentioned? (I do realize my n00bness is probably showing right now, but I can rise above that tongue.gif). Changing out the Air Intake doesn't seem that intense, would that be worthwhile as well?

 

According to AMS, just a filter change will do nothing. You need to swap out the resonator in the intake. They sell a delete for it. They also sell a block-off plate for the OEM BOV. I think you'll need to run a universal BOV, but you'll need to find metal pipe to weld the flange to.

 

I was looking through what those companies are putting together for a BOV replacement kit but I'm not sure they have a product to the market yet, maybe just working prototypes.

The one you linked would work for sure, but having the BOV closer to the throttle body would be a better design. The one in your link would be nice and simple to do though.

 

Been looking into one of these, since, y'know a RWD turbocharged coupe has some appeal for me.

Upgrading turbocharged cars in general is all about the boost.

Making that boost SAFE is paramount.

For the BOV, (because compressor surge really sucks) a generic fitment for an HKS (or clone) or Greddy (or clone) BOV is probably easiest. I don't know if the ECU on this is MAF based or MAP based, but recirculation fittings are avaialble for MAF based systems. (I have an HKS BOV with a recirc fitting on my Supra. It also gets rid of the shriek that the HKS unit has as it comes out of the box, so even when my MAP kit goes in this winter, the fitting stays.)

You can get pieces of pipe with the flanges for these pretty easy, so that should be easy enough to mount.

A better intercooler will also help, you'll get less pressure loss, and better cooling.

I personally believe that there's no such thing as too big an exhaust on turbocharged cars, though there's definitely a diminishing returns after a point.

For me, I'd make sure that the BOV is installed, and all of the pressurised intake piping is looked at before cranking up the boost. The car is new enough that it ought to handle a fair amount over stock without problems, but 17 PSI of boost is a fair amount of pressure, and a failure of a hose clamp or piece of plastic can get expensive REAL FAST. An ounce of prevention and all that...

For the factory BOV, I'll have to take a look at the dealership and see what it looks like. I wonder if the stocker from my Supra would work... Probably not much (if any) of an upgrade though. There's a reason why I replaced mine.

Okay, so once the intake is set up to handle the boost, and make sure that there won't be any compressor surge happening then it's time to start working on the boost. A MBC is pretty inexpensive, and effective. A few more lbs of boost are in order.

After that, it's time to start looking at the fuel system. Larger injectors mean more power, but that also means that you need a piggyback to control that power, or you have to fool the ECU into firing them for a shorter time. On the Supra, we can fool the ECU by replacing the AFM unit, allowing larger injectors, and thus raising the capability of the stock EFI system. A corresponding hack could be good for a few more ponies, and would be much cheaper than a stand-alone, but again, it depends on how the system works.

Edit: I haven't posted here in YEARS, and I've still got post count. How cool is that?

 

Well, welcome back! Lol.

(some of this is re-posted from my newbie post thread)

I am a 2010 genesis coupe owner from Canada.
its a 2.0t lightly modded.
so far with the mods I have done the car is proving to be a lot of fun smile.gif
I have outrun a few stock V6's with the setup the way it is now.

future mods soon to be done:
Front mount intercooler (blow off valve to be done at same time)
injectors
new turbo
new clutch
Kaaz 1.5-way LSD
stop-tech brakes
