ok i want to build a or my own upper intake plenum i was thinking on using 6163 aluminum anything that i need to know about it is it good for what i want to do with it and is it easy to weld as well as is it durableLincoln Power Arc 4000 Thermal Arc Fabricator 252 iThermal arc 186Thermal Arc 26 tigTweeko 200 amp spool gunHobart AirForce 400WP-17V-12R

Reply:yes its easily machineable , ive made hundreds of pieces , including intake sections with 6061 and machined more then i can imagine . luv aluminum !>Innovations are what i leave behind for History

Reply:Is that for the VG30 engine? There are a ton of things to consider. Do some research. That is a MAF/MAP application and they can be very touchy even with the stock manifold. What year is it? The egr system on that thing IIRC can be a bit of a booger too. Like a bazillion vacuum lines, some of them had MAP/BARO switches and you need to know which. I've never built or seen one built for that engine so I can't tell you firsthand what all of the pitfalls may be. Diameter of primary intake tube is critical if using the stock MAF. Linear distance from the MAF to the throttle bore too. There are a lot of guys on here that do this kind of thing a lot. Just a few things I thought of. If you have your old manifold I would chop it up and use it as a template or jig. Use your old mounting flanges and bolt your new ones to them to keep them from warping during welding.

Reply:Half baked idea?What exactly do you plan to WELD it with?This type project takes considerable research and detailed planning (as well as considerable welding skills).

Reply:I have to agree with Sundown. This isn't something you can just throw together and expect it to work right. If you are wanting performance, buy one or be prepared to spend lots of time and money on materials and dyno time. If you want looks, you might consider polishing the stock manifold (assuming it's aluminum).My name's not Jim....
Reply:performance and and space i have a turbo it is a 51t (t4 compressor with a t3 turbine ) that i rebuild about two years ago i already built the headers so that the driver side has the collector to the front and up for the crossover pipe passenger has a has the crossover pipe collector and the t3 collector as far as welding im using my buddies tig it is an hobart 165i im getting my flange and the tb flange water jeted and cnc machined to have a tight fit the velocity stack are also going to be machines out. the plenum main tube will be a 2 piece and o ring grooved or 1 piece gasket fitted.Lincoln Power Arc 4000 Thermal Arc Fabricator 252 iThermal arc 186Thermal Arc 26 tigTweeko 200 amp spool gunHobart AirForce 400WP-17V-12R

Reply:if ur serious about this , the hobart 165 isnt gonna weld 1/2" or 3/8" plate to well ( most intake to head flanges are that thick , to keep the mateing surfaces flat ) so if ur useing a 110v tig i would find something bigger . and welding round tube in a tight configuration is no easy task either . ... Also if ur useing a turbo and building the motor for turbo use . im assuming ull be getting a tune when u dyno it . so in this application if ur keeping the basic design of the stock intake and useing forced induction the intake doesnt have near as much effect on intake efficiency . as if it were natrually aspirated .. are u sticking with the mass air flow setup or going with speed density setup like a fast xfi , or another fuel managment ? im curious to see if u will attempt this or if ur just another talker .>Innovations are what i leave behind for History

Reply:this is what the VG33E engine is composed of The VG33E is a 3.3 L (3275 cc) version built in Smyrna, TN. Bore is 91.5 mm (3.60 in) and stroke is 83 mm (3.3 in). Output was 170 hp (134 kW) at 4800 rpm with 202 lb·ft (274 N·m) of torque at 2800 rpm. It has a cast iron engine block and aluminum SOHC cylinder heads. It has sequential fuel injection, two valves per cylinder with self-adjusting hydraulic followers, forged steel connecting rods, a one-piece cast camshaft, and a cast aluminum intake manifold. This engine is still in production in the Nissan Paladin produced by Zhengzhou Nissan for the Chinese Market.Lincoln Power Arc 4000 Thermal Arc Fabricator 252 iThermal arc 186Thermal Arc 26 tigTweeko 200 amp spool gunHobart AirForce 400WP-17V-12R
Reply:Wow, not an easy task to add turbo to that puppy. Is that a heater hose to the throttle body (prevents icing) or is that a vacuum hose, can't tell from the photo. Lots going on in that manifold... electric controlled idle bypass, EGR system with intake sensor. What are you doing for engine computer control? Good luck with the project.Side note: I worked in the Smyrna plant for six months in 2005, but not exactly on engine stuff (interior trim parts). At the time, they were building Frontier / Xterra / Pathfinder / Ultima / Maxima all in the same plant. Big place, very big place. zip, metro detroit

Reply:If it has a MAP sensor you'd better be damn sure the sensor and the computer can understand what boost is.My name's not Jim....NO not map it is a mass air flow sensorLincoln Power Arc 4000 Thermal Arc Fabricator 252 iThermal arc 186Thermal Arc 26 tigTweeko 200 amp spool gunHobart AirForce 400WP-17V-12R
Reply:I haven't really had to deal with a MAF sensor, but I would guess you want it before the turbo. It's going to read volume of air. After the turbo, the volume will be reduced because of the pressure. That might cause inaccurate readings. Plus, most of the MAF sensors I've seen have been right by the filter which would be before the turbo.My name's not Jim....

Reply:As stated, on a MAF/non map application the primary induction tube length is critical, but only because it determines the distance from the maf to the throttle bore. Are you aure it does not have a map? It is not always a one or the other situation, some have both, and the service manual says it has one. A lot of time nissan will stick them on the fire wall and just run the hose to the manifold. Like I said, Nissan Mafs are sensitive little things anyway. Are you running stand alone engine management?

Reply:Since when is a week of daily driving 600 miles? lolThe tech sounds like an idiot. When you 'reset' a PCM it really only needs to redevelop the long term fuel trims, which only takes a matter of seconds/minutes per cell, and there's only a handfull of cells.Welding/Fab Pics: www.UtahWeld.com
Reply:Originally Posted by MikeGyverMAF sensors read the mass of the air, not volume, hence the name Mass Air Flow They can go before of after the turbo (usually after), but need to go after the blow off valve (unless you're running a recirculating style bov maybe). You can't dump metered air or you'll peg rich each time the valve cracks.
