I was looking into a cold air intake for the 92 VG30E and haven't found much but did come across one made by option racing on a site called andys auto sports so i was just curious has anyone used one of these option racing CAI or know much about the quality of their product? Or know of a good CAI to go with thats available for the VG? I have the JWT pop charger and was thinking of putting it on the CAI.

What's wrong with what Nissan gave you to filter the air?

The stock intake is actually pretty restrictive if you've ever taken a good look at it.

Just make one yourself. The kits out there dont fit the VG

Or JWT and you make a heatshield! Gut out the OEM plastic intake tube restrictive points and keep!

Don't recommend it its just for the sound it won't help plus you will actually lose power in the long run because the throttlebody with get gunked up faster with carbon

That plastic intake tube is a heat insulator, and most intake kits use metal tubing with if you have a VG will run behind the radiator or in front of the engine getting blasted by hot air...

I have the JWT pop charger already. What restrictive point should be gutted from the intake tubing? I know the snorkel at the front can be removed but other than that what else? Maybe the accordian style rubber piece at the base of the intake and swap it with an HKS coupler or something?

A straight silicon tube might work better less turbulence...On he interior of the plastic intake tube the inside front and rear have restrictive like baffles inside them and they just need to be grinded down to allow unrestricted air flow...I suggest you read this cardomain article regarding a 1993 Nissan Maxima it's informative as hell!

Sorry but the cardomain format ws changed and all of his technical info has been trashed....Photobucket did the same to my picture acct but I caught their mistake just in time and had them correct it...I would've lost alot of photos! anyway remove your plastic intake remove the muffler and block that off but look inside the plastic tube you will see the baffles inside the tube...

Thanks for the info Cmax. If you don't mind me asking what materials did you use to make your heatsheild for your filter?

Just built a heatshield tons of air came from under the left headlight assy!

This is one of the best articles I've read on the topic.

decent article but it's really not relevant to what's being discussed here. we're talking about intake before the throttle body.

the article you linked discusses the intake manifold design and benefits of shorter or longer runner intake and along with exhaust pulses and header design.

nismax1994

Yes you're right. But I do think that there is more than just a sound-deadening effect engineered into the stock intake piping. I'll seek better reference.

I just want to say the even with my JWT the intake isn't that loud....even once above 3500 rpm it's not crazy loud but really nice, smooth and intoxicating!

I know this is not the answer you're looking for but you should look into a warpspeed y-pipe. I had one on my VG.

CMax03

Why would I downgrade to a Ypipe? I've got headers and a MES Catback on my 3rd Gen!

Quickywd01

iTrader: (16)

Because I have cattman headers, equal lenght y-pipe, fast-cat and I was talking to the member who started this thread. Also I just installed a y-pipe, hi-flo cat, and apexi cat-back on my beater. Don't think I forgot about you, the 3" exhaust is still needed to finish off the headers on the "other" car. Hopefully this spring I can tackle that and be sure I'll be asking you for help. MIght have to pay you too!

CMax03

iTrader: (3)

Might?????,
That's on your 4th Gen Of course, cause Cattman refused to make Equal length headers for the 3rd Gen! I install Pacesetter headers and Modified the Ypipe section and upgraded their design!

Thanks for the input. Iv'e had the resonator removed and ran 2 and a hlaf inch pipe and already had a custom made y pipe installed aswell as catback with thrush exhaust. Sounds nice. I also have the JWT pop charger. I was basically just wondering if it would be beneficial to run a CAI with the pop charger on it but after talking to DanNY he had a good point as far as hydro lock goes and is it worth the risk compared to any gains i might see. I may be interested in swapping the stock manifolds for the headers if it's a worth while mod though and if i don't run the CAI i may just make a good heatsheild like Cmax had suggested.

Quickywd01

Nice, I never got to go that far with mine. I think your JWT pop charger is the best thing you can have, a heatshield will help. For the CAI part I'd just run ducting to your existing setup.

Ya it's a 4th gen but not on my DD beater. You've helped the community a great deal with your exhaust dealings alone. So much so I would just pay you for a 3" when I get this thing running.

3" resonator section right???

Quickywd01

iTrader: (16)

3" cat-back with 3" resonator. I want the longest one you can fit with the flanges welded directly onto the resonator. And this muffler http://www.apexi-usa.com/store/exhau...urbo-80mm.html

nice muffler...i have the same one in chrome.

Quickywd01

iTrader: (16)

Yea! It really is. I have an apexi world speed cat-back (the old one which used to be chrome) on my DD '97 SE 5spd with an additional resonator, warpspeed y-pipe, and hi-flo magnaflow cat. Apexi sounds the best on these cars. Once they made the WSII (world speed 2) they renamed the original world speed muffler to noir now. I love the sound so much that I am going to put the "turbo" muffler version 3" on my supercharged car.

I have thrush on mine and find it sounds great and well contructed too. If you haven't heard of them checkout their site. I'd like to hear what apexi sounds like though. Iv'e heard of apexi for suspension i believe but i don't think iv'e heard one of their exhausts. I'd say post a vid to hear what it sounds like but iv'e found with video's of exhausts they don't seem to sound the same as they would in person which im sure doesn't do a nice sounding exhaust much justice.
