Hello everyone, first post here. I’m usually on the MKV Supra forums but I’m here searching for info for my buddy.

He’s thinking about getting a stinger gt1/gt2 but we don’t settle for stock power. I have a great tuner for jb4 custom map, so I’m covered there. I do need some links to performance parts, can’t seem to locate them from simple google searches.

Where to buy big turbos? Is meth sufficient cooling or is a rad needed? Is the ecu locked? And how much money minimal to break into 10s?

I know this is an entry level tuner car but I know some people mod the death out of these so I’d like them to chime in! Things like « you’ll enjoy stock power » or « you’ll lose your warranty » will be seen as unhelpful. Thanks everyone! Looking forward to being in the community

So the JB4 works for the Stinger as well, so you can use that to get a good amount of extra power, BMS sells a kit that has everything you need to make 400AWHP or 420-440RWHP depending on what drivetrain you get (AWD is faster in a straight line, RWD is better for track, Though keep in mind, ALL the AWD stingers can become RWD with the Pull of a fuse, you just still will have the extra 300lbs of the AWD system)

The BMS kit is about 1200USD on average.

you can also add WMI to make more power with the JB4, in some cases on here, above 500AWHP with other supporting mods

HOWEVER, if you really want to go fast, you need to get a dedicated ECU tune from either Lozic motorsports out of South Korea,

or

a Lap3 ECU tune, which are out of one of the Carolina's I believe.

While on paper, a dedicated ECU tune wont put that much more power down compared to a JB4, they WILL be significantly faster, as both ECU tunes can manipulate much more data for the car in real time.

There is actually a thread on this forum that has a list of the fastest 1/4 times that stingers have achieved, the fastest on record being a 10.9 right now. each of the top times lists at least all the big mods that each car had.

to answer your questions in order specifically

Dont go big turbo unless you TRUELY dont care about warranty (Also the only kit out there is like 12K)

Stingers love Meth more than your average Addict

A RAD is only needed if you plan to do Multiple high speed passes in a very short timespan, however it will give a couple extra HP because of the extra cooling even in general use, and some of them just plain look really cool on the car

the ECU's are not locked, but they are on the more complicated side of things which is why only a few shops are really good at tuning them

to get into the 10's consistently, you will need the following

ECU tune
TCU tune
WMI or e30/race gas
Intakes
at least a full Catback exhaust if not a primary downpipe as well
an Front mounted intercooler is probably a good idea
a Damn good Tire
Driver Mod

It will probably cost between 5-6K when all is set and done.

Mind you, this will be a high 10 second car on the drag strip, not the street. the street will probably run low-ish 11's

Hey, If I can chime in and add a few things.
First that list is dead and no longer maintained, we still post there but the list is not current. Here is the current list https://stingertop20.com/
You won't hit 10's unless you do weight reduction either. Wheels like RPF-1, Light weight rotors, CF hood, rear seats out minimun, ect.
Last, there's one ECU tune you didn't mention, Sxth. I run both the ECU and TCU combo and I'm quite pleased with it. Sxth is in SC and the support is great.

I specifically left out Sxth and Tork because they are not widely tested yet, also, one or two of the stingers that have had 10's only removed the spare wheel and are using aftermarket wheels for weight reduction, just a heads up.

 

[AWDGT2]

That's my point, not a single Stinger has hit 10's with stock wheels, spare in, or what ever it took to reduce weight. Bolt ons and ECU it just hasn't happened yet. Tork isn't widely tested? He's #1 on the list, Sxth is #2, I'd say there proven, just saying.

 

[AtomicGTL]

Imo weight reduction isnt super widely needed aside from wheels/spare removal. Dont need to use any cf or lighter rotors or gutting the seats. Ofcourse it helps but not to get into the high 10s not necessary.

Tork tends to blow up stuff, If I was a new stinger owner or passing on advice on tunes, Id recommend lozic or lap3/jb4 to the OP's buddy.

Consistency is key. Torks is the fastest yes but he blew his headgaskets up in the process, and Sxth just doesn't have that wide of an adoption yet as they are new to the scene, and while your car is fast, no denying that, its one of the only Sxth tuned stingers out there so far (as far as I am aware anyway). Im all for new players coming into the game, and their work is definitely impressive, But as of right now, Lap3 and Lozic have had much more time to improve the stability of their tunes for daily use.

Lozic blew Joel's head gasket, fact. Look, things happen. At some level you have to trust Tork, you have his TCU right?

True, things happen, iirc Joel was running awide array of mods at the time. But correct, anything can happen regardless of rep.

But terms of recommendation Lozic is more tune-able and has more options on the ecu, hence recommend.

No I have lozics tcu.

I do have his TCU, and his stage 1 tune works well and allows me to launch under boost, HOWEVER, I got the tune for $99. If I had to pay full price, Im not 100% sure I would have gotten it.

Can you link me to any information about Lozic blowing this Joel fellows headgasket? Ive pretty much combed the forums and didn't see anything on it, and Id like to know how Lozic handled the situation, as his customer support for me has been absolutely wonderful.

Lozic ECU + TCU + AWD Tune

I’ve heard that guys engine is toast and hasn’t posted here since august lol The best shift points for the ecu tunes seems to be at around 5k from 1st to 2nd and around 5500 to 5800 for the following gears. I already tore it apart and replaced the head gaskets a few months ago. It's running...

[AWDGT2]

It was unfortunate.... It was not catastrophic, the engine would overheat every now and then and he noticed *floaties in his radiator. Once he pulled it apart it was obvious. Joel and I chat several times a day, 7 days a week. We know each others cars just as well as our own. We chat constantly on ideas, tuning, mods, you name it. It's good to have a sounding board to bounce stuff off of, especially with a different ECU/TCU setup. We've learned a TON off stuff from each other over the last year.

Interesting, def not the case with my engine then, as I had no "floaties" and the Gaskets where fine. Thanks for the link! what's strange is I remember reading most of that info but not the part where it blew up. oh well.

 

[Vilithrax]

Wow I love the activity of you guys! Follow up questions:

At what point does the trans, axels, or engine need to be built?

And what aftermarket turbos have been tested and proven? Pure preferred.

What ethanol content can stock lines and injectors handle? We have 93 and e85 in my area.

Price is not an issue. This will be a big money car. Advice and direction is appreciated. Links especially!

 

[FSU Logan]

Is there not an option similar to what Pure turbos or CR turbos does where it is a repurposed stock turbo core (larger wheel/ported)?

 

[AWDGT2]

The 600 to 650 HP mark is where things go bad for the transmission. There are several big turbo stingers out right now but they are rollers, not 1/4 for the most part. The ones that do 1/4 mile fair well, and their trap speeds are what's most impressive.
As far as E. without a single upgrade, the Stinger can handle up to E30 safely. Sometimes more, sometimes less depending on the weather. If the Ethanol content is too high, the HPFP crashes and the car falls on it's face. There are upgraded HPFP's out there like Spool, but the Stock ECU is not programmed for anything more, so that bolt on is useless unless you're tuned for it. If you go with the Burger JB4 route (BMS), look at the CPI (Charge Pipe Injection) option. It basically adds a 7th injector into your charge pipe and is controlled by boost, load, duty cycle, all done from the app (user controlled). There are guys running up to E70 without a single hiccup, because it pulls from the LPFP side, not the high. It's like a Meth nozzle but better. Then with the JB, you can still pick your flavor of ECU and seamlessly stack those two. The ECU will take care of all the built in Nannies from Kia like torque limits, ect. and the JB can be used to log, control CPI, active gauges on the app, and EWG control. In addition, if you wanted to really push the car, you can easily add a bit of race gas and add a few pounds of boost per RPM in the JB app and go full send.

@AWDGT2 Thanks for that info!

Say I wanted to stick to jb4 pure turbo on e30. What hp can I expect and does the trans need to be built at that point? And for curiosity sake, how painful / expensive is the custom ecu clone process?
