Will a tuned 2.0 ever approach stock 3.3 power?

It appears that you have done everything that I have done to my 2.0 except I went with an Injen air intake and a custom exhaust. I do have a throttle controller. I drive on Map 3 everyday with Shell 93. You should try Map 5 with Boostane......it's a huge diff over 2 and 3. I am about to dyno Map 5 in about two weeks. I was born and raised in NJ but have lived in TX since 2008. You'll probably have a better chance finding a dyno shop and club up North in Union County and maybe around Trenton. Good luck.

You will never get to GT power levels unless you do a big turbo upgrade. I dont even know if there are bigger turbo options for the 2.0 yet.

That being said you could get pretty close to a Stock GT power level. Start by getting a JB4, Intake and exhaust. I have not seen many aftermarket parts for the 2.0 yet.

But honestly the real answer is you should of got a "GT" if performance was what you wanted.

The JB4 will be the best performance mod you can do to the 2.0.

Hope this helps.

The 2.0 genesis coupes are getting 700+ hp so the stinger 2.0 definitely can

Are you sure, you are not talking about 3.3? 700 hp from that 2.0 will be just ridiculous

And how many are doing that?

There are a few but also look at the money you have to sink into it there are a lot within the 500+ range though

I ran a dyno tested 331whp on my 14' K5 that had the turbo 2.0 in it. I had:

HKS spark plugs
JB4 on a custom map (running 23psi)
a custom mix race fuel (appx 109 octane)
Magnaflow Cat-Back
CXRacing FMIC w/Intake
ADD1 catch can
Stuffed turbo (factory housing with enlarged compressor wheel)
Modified Wastegate

In my opinion:

For a streetable daily driver, that's about the most you can safely do without either WMI (Water/Methanol Injection) or more boost (meaning a bigger turbo) and when you get to around 350+whp, the stock internals are going to be at risk, so most folks who are running that number or higher have done their internals, and a fuel system as well, A LOT more $$ at that level. The cars going north of 500whp would also need strengthening of the drivetrain (axles, trans, solid mounts, ect) and will have serious challenges getting traction (if its not AWD).

Making 700whp strapped to a dyno is VERY different than trying to get that power to hook up on the street or at the track.

I chose to spend the money to upgrade to a 3.3 Stinger GTS before I put that $$ into the 2.0.... ESPECIALLY when you consider the known internal failure issues with the THETA II engine. (TBH, I'm not familiar with the 2.0 variant they put in the Stinger; if it does, or does not, have the internal issues that the 10'-16' turbo 2.0 K5's have...)
