Mishimoto G37 Direct Fit Catch Can Thread

Hey Guys!

Happy Wednesday! I'm going to you from our HQ in New Castle to let you know we've started development on a direct fit catch can kit for the G37!



In this day and age, if you’re an enthusiast in search of a naturally aspirated, performance-oriented 6-cylinder, you’re almost out of luck. The last 8 years have been the age of forced induction with the 4-cylinder turbo layout edging the V6 closer toward extinction. Unless you have the money to spend on a Porsche, there just aren’t many options out there anymore for the fun 6-cylinder.

There is one manufacturer, though, who can deliver the “Fizz” (as James May would put it) without the fuss of a turbo or supercharger. That would be Nissan. I’m sure that most people would have visions of the dime-a-dozen Rogue or Sentra that dominates the roads these days. Anyone who knows anything about their Nissan and Infiniti is quite aware of the company’s heritage. From the long-nosed Datsun coupes to the drifter’s dream that was the 240SX—and let’s not forget the 10+ generations of the Skyline/GT-R—Nissan has proved it’s been around the block a few times.



The G37 released with Nissan's newest rendition of the VQ engine, the VQ37VHR, sporting all of the amenities which made it one of the most versatile, and efficient V6's around. Of course, that doesn't come without drawbacks. The combination of direct injection and high compression makes this engine highly susceptible to engine blow-by.



While this might not have come from our loaner G37, it could end up looking the same if left untreated. Luckily though, we've already been hard at work developing a catch can system to guard your intake valves from the contaminated crankcase pressure. Make sure you head over to our Engineering Blog to find out what we're planning!

Feel free to shoot me any comments, questions, or concerns you might have!

-Nick

Our engines are port injected.....

Yup, no denying that I mixed that one up.

In either case, we found that blow-by is an issue that we found on the VQ37, which I'll dive into with our next post

Someone else made an awesome one that integrates with the coolant overflow, all welded aluminum, nice hoses etc....and it's around $600. That MIGHT sell to a couple of show-car owners, but that will be minimal. My point is, if you're gonna make it higher than $100, don't bother. There are a lot of catch can systems that can easily be used on our cars, that are well under $100.

That being said, if you can make a nice one for less than $100, I, like others will be very interested.

Yeah, I am not real sure why they are using two cans for a V6 either. I am sure it was just easier for THEM seeing as we have dual intakes. While I appreciate their effort, I'm questioning their build process, and ultimately their eventual price for a dual can system.

SOHO Motorsports


More options are always good for everyone though! Right now I'm liking how SOHO integrated the return into the dipstick.

What features will the Mishimoto have?

yea but theyre just so damn expensive. i come from a g35 and before i installed my oil can the top of the intake manifold (inside) would be all smeared with oil residue. after the can it didnt have the mess anymore. does the g37 have this issue? i dont see many threads regarding the g37 intake manifold and taking it apart and cleaning it.

No but we do see threads about cleaning their throttle bodies.

nm looks like the g37 intake manifold cant be taken apart like the g35 one. its just one solid piece so we dont even know what kind of gunk has built up in there . is this correct?

Glad to hear it! We don't have pricing details just yet, but the presale is coming up quick! Keep an eye out on here for the link

This is actually a great question! So there's two reasons why we went with the dual compact can setup of a multi-port tall can. The first of which was just because of a lack of space. Our engineer spent a good amount of time poking around in the engine bay for viable mounting locations, and the front mount with two cans was the best option.

The other reason is, yes, because of the dual intakes. Each bank is sporting its own separate PCV line. We could potentially combine them, but that could lead to potential emissions issues down the line, since each bank is going to varying pressures running through their systems. Also, being able to check each side independently of each other will be able to give you some indication if one side or the other is having any potential issues.

Unfortunately, we won't be able to hit the $100 mark, but we will be offering it on presale very soon at a steep discount!
