Would an 1989 C.A.I. fit a 1986? Without modifications? Or should be like Ian and buy a supercharger?

 

Last I knew there were no easy supercharger kits for these cars, hence my decision to do the VG30ET swap. I am going to build a C.A.I. for my Maxima using a fiberglass box and a turbo hood scoop from a 300ZX, subtle but needed.

 

Your going to have to make one. Here are some pics of mine below. Also Be sure to cut and paste the links in a new window browser!!!!. You might have to enlarge the hole where the factory intake air comes from the fender. You can get a 3in or 2.5in pipe made/bent at a muffler or you can use 3in aluminum dryer hose tubing from home depot. If you make yours like mine you will have to move the battery to the trunk. But if you were to run it like the factory setup you don't have to. Either way you might have to enlarge a hole or make one. I gained 11whp/13wtq from my CAI, most cars don't get more than 5hp from an intake but mine did.

Your gonna have to do some modifcations to the CAI in order to make it work. I've been working on doing a custom CAI for my car. So far I done some of the housekeeping, but I need to get the filter, the tubing (and I'm wondering if I can use the aluminum duct, or go with PVC), and then I have the cutting to do. If I ever get around to doing it, I don't mind showing it to you if you want to get an idea of what you need to get done.

Just be extra careful when you guys go with a CAI setup. Chillin, a member over at the 2nd gen club at Yahoo installed a CAI. Back in August he drove through a lot of water, consequently sucking a lot of it up into the engine and seizing it.

He said he was looking at an engine in October, but that's the last I've heard from him. Hopefully he'll be able to get a new engine, as his car looks really sweet, he recently got a custom paint job and a lot of other cosmetic work done to it. Check it out in the photos section at the 2nd gen club.

I've heard of a thing that you can install to the CAI setup that will keep water from going in. I don't know how well it works, so I just stick with a HAI. I've got the cone filter attached directly to the MAF, it definitely increases power, the engine really purrs now, but unfortunately the AIV isn't hooked up (doesn't matter since it destroyed my old MAF), but I've got emissions inspection next month and I've heard that has to be hooked up to keep the emissions down. Though that info was about other cars, I'm not sure if the same is true with the 2nd gen. Anyone that has this setup or a CAI and has passed emissions with the AIV disconnected, let me know.

Something about hot air in the AIV actually increases your HC and Co2 count. Or at least that's what one of the smog referee said the last time I given a ticket for my CAI.

Basically to avoid inducing water, you can buy a bypass valve. This valve is sold in 2.5, 2.75, & 3 inch sizes. Basically what you do is put this in between the filter element and the MAF adapter that is high and dry. What happens is if anything, water or dirt clogs the filter, vacuum increases and forces open the by-pass valve. Allowing air to enter there. A nice precaution for $40 bucks or so. As for the AIV, it causes hot air to enter the exhaust and supposidly increasing HC and CO levels. A way to combat this is to buy a long air tube, route it with the CAI through the fender and putting a small breather filter or minature cone filter on it so it gets cold air. Though with a HAI, just run the tube through the old opening for the intake duct. You can probably mount it by the Cornering assembly to ensure you get cold air.

I saw a guys post a while back a CAI install and he ran his hose down through his left front panel. I am not to sure how I would do mine, but I need to know if CAI will fit the intake system of the Maxima.
I wonder why they made CAI for the newer models and never considered any early model Maximas?

 

There really has never been an aftermarket for the second gens. If any CAI kits are going to work, the third gen VG30E one might be the closest, you will have to do some modifications though, because the 3rd gens route the intake around the radiator side motor, where the second gen route it through the tranny/firewall side.

That was Chillin's CAI, it was great, but the problem is that a little flood or splash in a huge puddle, your engine is going to suck in water.

I wish I still had my 88, but I am on the lookout for a low mileage 88 Black SE with grey frost interior, low mileage and a stick.

well today i spent a few hours at the local junk yard trying to figure out and easy nn costly way to make a performance intake and find a possible interchangeable MAF adapter of another car/model
but first i have a qusetion does any one kno if the MAF sensor off an 85 300zx is compatible with our cars? because if it is i may have found the solution to the whole MAF adapeter problem ...as in u wont need one because the 85-89 300zx has a double sided male hose attatchment this would rule out the MAF adapter. tho i may have found a way to fabricate a CAI, out of 85-89 300zx intake piping. this commin week end if i can get some help. (good help is always hard to find...lol) to spend a few hours testing the constrtuction of one these intakes on one of the 40 or so maximas at the junk yard. if this works its going directly into my car. and i'll be able to post schematics on how to do it ive go the majority of it done now to install it and see the fit on a max. any help or suggestions i would be greatful thanks

See the second generation club, I replied there.
