A2A Intercooler fit for '15+ Nismos?

bcfromfl

I'd really like to install an s/c kit in my 2015 Nismo, and was part of the plan when I purchased it, but I can't seem to find pics or descriptions of anyone who has done it. Google was no help. I found a YouTube video of a 2016 Nismo that had an A2A kit, but it was just a 35-second dyno pull with no other information. I don't want to put the guy's name here, but I'm fairly certain he's a member of this board.

When I examine things behind my bumper, I'm seeing all sorts of potential problems to fit the intercooler. There's a vertical black brace right in the center in front of the radiator (probably on all Zs, so maybe not an issue), and a "Nismo Performance Damper" that's the same length as the crash bar, and sits just above and behind the oil cooler -- with 3" between it and the radiator. Part of the problem is I have no idea where exactly the intercooler sits. Does it go in front of these obstructions? Doesn't seem like there's enough room for that.

At this point it looks like the crash bar is the least of my worries.

Are there different installation issues with respect to Nismos? Are there any '15+ Nismo owners having unique difficulties especially with the intercooler? Suggestions? Smaller Mishimotos?

I'd hate to ditch the idea altogether, but may have to if it involves too much custom fabrication.

Thanks!

I have a 2015 nismo with a supercharger and a 2017 nismo with a turbo ..there is plenty of room for front mount intercooler ....you will loose the front damper with both .....I did lose the crash bar with the turbo kit but not with the supercharger

Hmmm...I'm not sure I want to remove the damper. I'll have to think about this...

I haven’t noticed any difference from it..also I have pics in my album of the supercharger intercooler

If it weren't for the dang tow hook, I could hang a smaller Mishimoto right underneath the crash bar. That would catch all the potential airflow through the vents, as there is no benefit to having a taller intercooler core sitting behind the crash bar.

Maybe I'll check with Z1 or FI to see if they have any ideas.

Even behind the crash bar it’s benificial ..... it the joys of the boosted world ....good luck

I just crawled around in front of the bumper with a flashlight and a tape measure, and I think I can make this intercooler fit if placed to the left (facing front) of the tow hook: https://www.z1motorsports.com/interc...ic-p-4471.html I don't know where the mounting points are on the intercooler (hopefully on the edge of the frame), but probably I'd have to tap threads into the back of the crash bar. I'd have to make a bracket for the underside, too, of course, but the unknown is how to fit the BOV. Maybe a curved 180 pipe and place it behind?

Is there a rule of thumb with respect to how many inches long a piece of silicone pipe can handle, say, 9psi? There are custom mandrel-bent pipes, too, and if they're the right length, maybe I can get away with rubber/silicone collars to join them.

More of a project than I really want to tackle, but I'll give it a lot of thought, and maybe others can chime in with ideas? Thanks!

I may be wrong but I don’t think that will be any better than the larger intercoolers .... there is more to the cooling effect than just the airflow going to it ..volume of the intercooler is a factor to be considered as well

People often have an incorrect perception of how an intercooler works. Air isn't cooling down your charge temps, aluminum fins are. All an ic is, is a giant heat sink. The fins literally absorb heat then dissipate it out to other fins which get air cooled which in return re-cool down the interior fins that the charge air is passing through. An efficient cooler will absorb the heat, then cool itself back down and this cycles when you go in and out of WOT. For most street cars the amount of time spent in boost will not force the ic to remain in a "heated" state and by the time you need boost again your back to ambient.

Thanks for everyone's comments!

After a little more research last night, I discovered that the Mishimoto I linked is only rated for 350hp (not sure exactly how they arrive at an arbitrary rating like that). I checked Treadstone, and found they had an intercooler with actually a slightly smaller profile, but 3.5" deep instead of 2.25", and is rated at 500hp and a 750CFM flow rate.

Also found several YouTube videos on how to make a budget bead rolling tool out of a crimping wrench. So, once I cut various sections of piping to size, I can roll the ends to make secure seals. Hair spray is a recommended lubricant to help slide on the silicone couplers, because when it dries, it's almost like a light glue.

Mishimoto is the worst shitty Chinese crap you could possibly put on your car.

You're overthinking this again. If you want to have a supercharger, buy Topgun's kit and go on about your day. All of the concerns you mentioned here are not problems and there's a reason everybody installs their intercooler the same way.

It makes sense to have a larger intercooler with some of it out of the air stream. By going to a smaller intercooler that has 100% of it in the stream will not gain anything at all, except probably raising your intake charge temps.

I'm not trying to gain anything with a different intercooler (and I realize it doesn't have the capacity of the one in the kit) -- just trying to avoid removing the damper and cutting issues on the crash bar. I can see myself bolloxing that up royally if I try to do it myself, and I imagine having a welding shop do it will take some coin, too, that I could put elsewhere.

Im not sure if the 2015 is any different behind the bumper... But I had no issues with the Damoer fitting with TopGunzs A2A kit...Crash bar is any easy fix...just order the Fast intentions one....fits like a glove on a champ.

Thanks so much for the pic -- helpful. I can't see the damper in your photo, and it looks like you don't have the OEM oil cooler? Not sure.

I was concerned about the Fast Intentions crash bar, because in another thread on this board a member said theirs didn't fit the 15+ Nismo bumper. I suppose it's possible he was sent the wrong crash bar...but it contributed to me considering different options just in case.

Is your BOV just supported by the hoses and clamps, or is there a bracket for it, too? Any ideas how to plumb the output back into the intake to cut down on noise? Another idea I read somewhere here was to put a tiny filter on the end to act as a muffler. Can't find that suggestion now...
