PTUNING Turbo Kit Owners Topic

[sw20kosh]

@mkivsoopra and I just came back from pounding on our turbo kits yet again at Laguna Seca Raceway. Cars ran flawlessly hot lap after hot lap in the unusually warm weather for this time of the year(75-80 F ambient). Video to come soon!

Toan's (ptuning) tune was perfection out there!

After a year of going FI with the PTuning turbo kit, I think it's time for a recap!

Total mileage: 26k on the chassis, 11k with turbo kit
Car usage: partial duty commuter + weekend track monster
Relevant mods:

• Flex fuel, 95% of the time on pure E85
• Exedy Stage 2 clutch - Stage 1 slips after ~320 lb-ft
• Setrab Series 9, 25 row oil cooler
• Koyo radiator
• Toan tune
• JDL UEL header

Boost level: daily 9.5 psi (~350 whp), fun 14.5 psi (~450 whp), track 7 psi (wastegate ~300 whp)
Number of track days: 12 - Ambient temps ranging from 70s to 105s, usually on pure E85 or mixed down to E50 at minimum

General Issues Experienced (not necessarily specific to the kit):

• Nut holding header to turbo overpipe came loose at the track after 5 months
• Front right anti-sway bar bushing started to melt from the turbo heat at extreme track temperatures
• Blown coil packs #1 and #2 due to track heat
• Extreme oil temps solved by adding oil cooler (have not tested PTuning oil cooler)
• After a year, brass T fitting for the oil supply and oil pressure switch showed signs of leakage. Needed to remove and reapply thread sealant/teflon tape.
• Disappearing water from cooling system - pressure tested ok, not fixed yet

Overall, I'm still very happy with the kit. It's been dead reliable, especially pushing the car to its limits in extreme conditions at the track. This setup absolutely terrorizes other cars at the track. They never expect this kind of speed coming from our cars. Most of the issues I've seen have been heat related, and they only surfaced during the hottest of track days before I had the massive oil cooler. I can imagine front-mount turbos to have 5x more problems with heat. Well-thought-out design, @ptuning @Mrc@ptuning
@sw20kosh has been there with me at almost all the track days. He can attest to the robustness of the kit, as he's been putting it through the same torture test with similar results.

I was looking to go with the Sprintex 335 supercharger, until I came across PTUNING. How is the reliability with this kit for a daily driver? I'm looking to attain 300 to 350 whp.
This video makes me think turbocharging might be a better option. Is turbo lag much of an issue? Feedback appreciated, thanks.

I can't recommend it enough. Has been bullet proof even with all the tracking I have done (11 track days so far). Support from @ptuning and @Mrc@ptuning is fantastic.

My car was their test car for quite some time. I gave Ptuning my car for several months (only with 950 miles break in period) and they used it to develop their turbo kit. My car to this day is running strong with several hundred of those miles being hard core WOT dyno pulls. Car has 22k miles and has been running flawlessly since day 1 in the very meticulous hands of ptuning. I can't say enough great things about the folks and their attention to detail. I will be embarking on a 1500 mile road trip in upcoming weeks and I expect 0 issues!

+1 on the recommendation. See my post above. 14 track days so far now. Turbo lag is not an issue at all, especially on E85. 91 is not bad either!

I run 94 octane since I am in Canada where there is no E85 available. From reading online it seems there is some risk to blowing your engine with the 335 twin screw supercharger. On the lowest PSI rating with this kit, I would assume this is a safer option? It seems this kit makes horsepower so easy, although I guess this is because it is a turbo! I was going to have custom tuning done by Moto-East, but I see they do not even sell this kit. Can you guys point me towards a good tuner and/or a reputable seller of this kit?

Toan (ptuning's tuner) has done many remote tunes for this kit.

Also James from HRI Tuning has done tunes for at least two ptuning turbo kits (mine and @mkivsoopra 's)
