Did you notice significant increase in NVH (noise vibration and harshness) transferred to the cabin? It is very very prominent upon deceleration with the transmission engaged. Seems to be worse right around 3k.

I am thinking about uninstalling my whiteline diff bushing inserts to cut down on this NVH.

I believe my throw-out bearing is causing some small vibration in the 850-2650rpm range. I'm going to swap that back to the OEM one when I install header / oil cooler. I will be keeping the light flywheel though. My NVH isn't bad.

You may want to re-consider opening up the transmission again...

It took mkivsoopra and I 8-9 hours to install the clutch. The turbo and oil scavenge pump really do get in the way. Also, about 1/3 - 1/2 the intercooler/intake piping needs to be un done and re-done.

Just a heads up. @mkivsoopra can chime in here too.

Oh I know what it takes. I put it all in myself and had to remove the turbo once already to put in a new gasket on the over pipe.

I'm going to do a big check-in on the 3k mile mark and dismount everything to check wear and tear, if any, while installing several components.

As you all know our PTUNING Oil Cooler System features an oil/water Laminova core. There is nothing unusual about our turbo set-up that would have prevented us from developing a simple air/oil cooler system like others have done. In fact, we use conventional air/oil coolers on our other turbo setups (S2000, tC). The only reason we opted not to go this route on the FT86 is because of the engine/bodylayout. This car has a very small frontal opening in addition to a short front bumper overhang.

A regular air/oil cooler system either needs to block the intercooler or go between the intercooler and condensor. Either way it ultimately ends up blocking the radiator, which is a big deal on this car, since the frontal opening on the bumper cover is rather small to being with.

The other option would be to place an air/oil cooler in the fenderwell in front of either wheel. The problem we saw with this was, due to the short bumper overhang, fitment was very tight and it is difficult to direct much air from the frontal opening off to the side and into the cooler. Furthermore, it requires swiss cheesing your fender liner in order to obtain proper air flow through the cooler. Sure, it's possible to cut a giant opening in the fog light opening to direct air to the cooler, but not everyone will be okay with modding their front bumper cover like this. Also, we wanted to keep both sides of the bumperwell area open for future development of a brake duct system for customers looking to seriously track their cars. It's also why we tucked our WMI pump and washer reservoir into the cubby hole under the factory bumper beam supports.

Now, on to our oil/water cooler system. We developed a custom bracket system to allow our Laminova cooler to bolt to exising holes in the chassis so that no drilling is required (easier said than done LOL). We also positioned it in a way to allow us to run the shortest possible oil cooler lines from the engine to the oil cooler as well. Between the very short oil lines and the inherent free flowing laminar fin design within the Laminova core, overworking the oil pump and/or oil pressure drop will not be a concern.

Unlike some other implementations of the Laminova core, we do not depend on fittings welded to either side of the radiator end tanks to provide water cooling to the core. This method is definitely not very efficient since the amount of coolant flowing through the core will be minimal. In addition, the hot coolant that has not had a chance to pass through the radiator is being used to cool the oil.

Our design uses the full flow of coolant exiting the lower radiator hose AFTER it has been cooled down by the radiator. Doing this requires us to mold custom silicon hoses though. Our unique hose routing ensures that the engine is allowed plenty of freedom of movement without putting any strain on the lower radiator hose.

Lastly, the design of the Laminova core allows for full, unimpeded flow of coolant through its core. You will not be putting any additional strain on the factory water pump by running the engine coolant in line with the Laminova core.

Hope this explanation helps.

Any pics?, ETA?

Sounds cool!

Yes, guys... Do your clutch first!

Next question is ETA? Saw 265+ F at the track yesterday, with not-so-aggressive driving... Will be waiting for the oil cooler before I attend another track day.

On the other hand, the turbo setup performed flawlessly.

I hope these extra parts arent hella expensive. I wanna be done with modding the car and just enjoy it already lol.

Street driving you'll be fine without oil cooler. Just if you plan to track the car it would be a good idea.

Took my car to track yesterday and had 0 issues! I will upload a short video later, but my GoPro decided to turn off after 2 minutes of everytime so I do not have very good footages

[bjun]

First time at the track. As mentioned above, had 0 issues. It's unbelievable how much fun the turbo adds to this car!

"You've got a lot of power"

Lol, I liked hearing that. That's a sweet track! I wanna come out there for sure someday.

Hahaha ya and he has a modded GTR lol
He took me in his gtr and I'm glad I didn't buy it. Turbo brz is light and tons of power so its extra fun at the track!

Ya TX has some great tracks! Hit me up if youre ever here! Lol
