Hey everybody!
As some of you may have seen in the last couple of days, ahardbody has mentioned about a new intake system for the ga16i. I am a mechanical design engineer, co-founder and co-owner of L&P Performance ( http://www.ifwda.com/L&P.htm ). Ahardbody has been a long time friend of mine and has recently informed me about the lack of any intake upgrades for the ga16i. L&P Performance is a new business I started with my best friend... we specialize mostly in Nissan Truck/SUV suspension and engine performance upgrades.... however, I will be working closely with ahardbody (and hopefully some of you as well) in the next few weeks to come up with a suitable intake system/components for the ga16i. Additionally, I will very likely be coming up with a machined intake spacer to separate and insulate the throttle body injection from the intake manifold, aid in fuel atomization, and add volume to the intake manifold itself. The intake system will most likely utilize a cone-type K&N filter and a fully mandrel bent hard pipe, and the crowning piece, a machined and port-matched intake adapter specially made for your throttle body injection.
Anyhow, I just wanted to let you all know of the ensuing plans, and to ask what you all would like to see done with this intake system. I have the resources to do just about anything, so let me know what you think. I also want to know what kind of prices you could deal with. Please post up a storm and ask any questions you have so I can see what you all are looking for. I'll keep in touch and check here daily.
Sincerely,
Lee McQuinn
L&P Performance

That will be great for us GA16i owner. One problem will be hood clearance after installing the throttle body spacer with the intake adapter. I have a Pulsar and the hood clearance from the top of the intake isn't a lot. It might not be a problem with the B12's though. Also you have to take into account for strut bar clearance.
Good call, Mervic. I planned to design the system to fit under the hood.... I might possibly machine the intake adapter with a "side exit" instead of straight up.... that way you dont have a big tube sticking straight up from the throttle body towards the hood.
As far as the spacer is concerned, it will be approximately an inch to an inch and a half thick... probably a fiberglass reinforced plastic, or resin, for insulating purposes... if not, aluminum with insulating gaskets included.
For the strut bar clearance.... I want to see pictures, from all angles. Heck, let me see all the pictures you have for anything in the intake system... the more, the better.

how about doin a CAI that extended from the side of the spacer and for those wit strut bars find someone that has a b12 and measure the clearances so that is can fit with and without one also thanks for helpin out with this
Well I don't know if this helps but I'm in the market for an intake that's going to be easy to install...and also something that will work with future mods like exhaust, cams/valves,etc. I'm assuming that if it's an intake that's geared for hp increase that it will be priced accordingly to demand of the product. So here's hoping that it's in my price range.
What kind of price range would everyone be ok with?.... be realistic, I have to make a proffit. The intake will be very easy to install... and come with everything you need... and it can only help your engine flow better, regardless of exhaust or anything else.

Thank-you for taking such an initiative! It would be great to finally have some off the shelf parts for the GA16i! As far as pricing goes heres what Id be comfortable paying:
$200 CDN before shipping and taxes for the piping, adapters, and a mounting bracket (note where the OE one is, Id suggest taking advantage of that). The filter could be sold seperate as they are usually the most expensive single part of the set, just make sure you give us a K&N Part number!
What will be the size of the intake tube, 2.5", 3"? I think 2.25-2.5" will be ideal since the GA16i has a crappy head design. I think it will give more velocity for the incoming cold air if the pipe diameter is not too big. Someone correct me if I am wrong?
Hey guys.
I am fairly confident I will be at or below $200 for the kit, might even be able to throw in the filter at that price... I'll know an exact price when I finish ahardbody's intake.
For the pipe diameter, its still undecided as to exactly what size will be used.... the main problem, as I have discovered, is the mass-air sensor sitting right next to the intake opening. Just as my VG30's throttle body injection in my Pathfinder, you have to supply air to the sensor in order to work right, and it has to be exactly proportional to the origonal flow rate calibration so it will inject the right mixture of fuel... you cant just shove a pipe over the throttle body opening and call it a day. That being said, I will most likely be forced to use a large enough diameter pipe to completely fit over the whole round part on the top of the TBI unit.... from there I will be able to decrease the diameter of the pipe for the rest of the intake system to help out with velocity (yes your right Mervic).
By the way, now that the issue of cylinder heads comes up... if your port designs are anything like the ones on my SOHC VG30I, I can do WONDERS for your cylinder head flow capacity. If anyone wanted to lend me a spare cylinder head, I'd be happy to inspect to see if I can do anything to help the head flow better. Assuming there is, I'd do a full port and polish job for cheap so that person could test it for everybody here on the board... if anyone has any real interest in it, let me know.

I've got a spare cylinder head waiting for a port and polish. I could donate for testing. PM or email me details.
New ga16i intake options!!!
