Burger Tuning JB4 for Kia Stinger!

[StungBlueGT2]

On my stock pull I did right before the move to map 2, I got a peak MAP sensor reading of 28.396PSI by meter, and 26.67PSI by ecu via OBDII. That is 14.106PSI by meter or 12.38PSI by ECU of boost.

Full disclosure here: The OBDII readings are being done at approximately 3 times a second, the meter has a hold speed of 32 samples a second. Meter is reading almost directly at the sensor and through about 10ft of lead. Meter has an accuracy of 0.5% of the voltage reading, which equates to roughly +/- 0.15psi of accuracy.

My thought is the fluke meter is capturing better peak values due to its sampling rate. If I take my fluke stock vs fluke map 2 reading, we are talking about a difference of 4.776psi of boost, which is closer to what the JB4 should be doing. The OBDII numbers are closer to what the community is reflecting about the stock boost pressure.

Thank you much for clarifying and those numbers seem to make a lot more sense.

However, am I wrong to think that almost 5psi or 40-45% more boost is pushing the limits of our little turbos and other stock parts? I cant seem to find any info on the type of turbos our 3.3TT uses, let alone the recommended boost range. This just seems to be quite a lot of extra boost for stock plug gaps, stock plugs in general, and possibly our turbos?

It most likely is. After seeing all the issues with stock spark plugs at their current gap your assumption is one I agree with.

The turbos are Honeywell A/R 61.

Yeoman work being done in this thread! Keep it up, owners!

Thanks and that's more than I could find, but unfortunately that's only part of the info which describes the Area/Ratio of the housings. Think we need the model numbers of the inlet & housings, like Garrett GT30R or T3/T4 etc. to determine max recommended boost PSI.

Here's a pic of the plate on the housing. Not sure if that helps.

Based on what I can tell from the close up pics I've seen, stock turbo looks like a Garrett gt series frame. Something akin to a gt2252, with a 40mm compressor wheel. Pretty tiny really. Turbine wheel looks ok. Stock turbos will probably Max out around 500 hp @ 20psi. Lots of room in this engine bay though. Would love to see a offering with the new Garrett g25-550s on either side

Is that your turbo? Driver side or passenger?

The turbine looks different than mine and the blades look beat up.

 

[KLR STINGER]

Based on the picture, the 28232-3l100 is the part number. Could not find any exact match, but every other turbo with the 28231 prefix is a gt17. My guess would be something like a gt1752s variant.

Get that turbine wheel fixed ASAP! WTH went through your intake???

This was a failed PDI at the dealer on receipt of car.

Correct. Picture taken from a thread titled "First Stinger Motor Pull."

Whew...

@Dustin have you tried map 2 since switching plugs? Any thoughts?

 

[jdouga]

Has anyone been able to log and send any info. to Terry?

I have not yet. Weather is really crappy and been working long days since plug change. First nice weekend day we get here I’ll be testing it out.

My car is at the dealership getting all the plugs and coils replaced.. They, like others have mentioned that Kia knows of the weakness/faults of these items and are looking into solutions.. So I would expect a future recal..

Once I get it back, the plugs will get regapped and away we go with the JB4 and the REV3 combo and the K&N drop ins..

I know the coil are on back order. I got 2 in today and waiting for the other 4. The left and right bank have different coils.

Just re-gapped the stock plugs. I gapped them to .28. The car runs absolutely amazing! No break up anywhere. I followed @TorkMe's guide, very very helpful. I will be running map 2 tomorrow.

This is exciting.. thanks man!!!
