TomoHawk Posted January 1, 2004 Share Posted January 1, 2004 78 280Z Anybody try to remove the metal between the runners on the intake? I think it might be somewhat beneficial by letting the heat from the rexhaust headers underneath get through faster, thus cooler fuel mix. It might look a little nicer too. thx.

240hoke Posted January 1, 2004 Share Posted January 1, 2004 it shouldnt be too hard, but I wouldnt bother with it. I would look for an N42 intake manifold off an early 280z, they came from the factory without webbing. The webbed intake is actually to heat dissapate heat from the intake. i sraped it though, it has alot of emissions on it and is just plain ugly. Go for the N42, it will really clean up your engine bay. i picked one up for $50 with the whole works injectors tb and all. -Austin Quote Link to comment Share on other sites More sharing options...
TomoHawk Posted January 1, 2004 Author Share Posted January 1, 2004 I think I figured it out... If you remove the webbing material, you have a bad fire hazard. If the fuel hoses ever start leaking, it goes down onto the hot header pipes and you get FIRE. So I think I will have to live with the ugly, unless somebody comes up with a good idea. thx.

pallnet Posted January 1, 2004 Share Posted January 1, 2004 the webbing is bareble if you shave off all the nipples and unused fittings then powder coat, paint or just plain polish the crap out of that thing. look at your intake closely. there are drain holes at the flange in the middle of each webbing. this is to drain off water but, if you have a leak, it will drain off also. the holes are right above the E manifold.

TomoHawk Posted January 1, 2004 Author Share Posted January 1, 2004 I never noticed any drain holes; that's why I was asking. The day I got the car, the hose connecting the 2 halves of the fuel rail split and gas was dripping into the intake, collecting in pools between the runners. It would've been a short ownership if the gas dripped on the exhaust. Another time I was cleaning the valve cover and the rinse water collected between the runners. Maybe tyhe drain holes were toward the front? I had ALL the fuel lines under the hood replaced since. Quote Link to comment Share on other sites More sharing options...
Roostmonkey Posted January 14, 2004 Share Posted January 14, 2004 Pallnet's right there are drain holes at each web,yours must have been clogged.I'm in the middle doing this to my intake right now.I used a plasma cutter to remove the bulk the webbing and a dynafile to smooth everything out.everything has been removed from the top of the plenum and welded(except the brake booster and boost guage holes) and polished to a mirror finish.The other needed holes have been relocated to the side to keep it clear on top.I still need to match port everything and open it up for a 60mm TB.I'm making a polised s/s fuel rail to match the I/C plumbing and powder coat the valve cover.Should look and run preety sweet.

TomoHawk Posted January 14, 2004 Author Share Posted January 14, 2004 I need a fuel rail too, but polishing would be too ggod for my engine. I would just run some fine sandpaper over it. thx. Quote Link to comment Share on other sites More sharing options...

An N42 with a proper head shield will be cooler. That's why the turbo manifold has a heat shield as well. But I like the idea of cutting out the webbing on a turbo manifold, retain the heat shield, and otherwise cleaning it up. It should work well.

TomoHawk Posted January 14, 2004 Author Share Posted January 14, 2004 Since ther is so much air going under the carm causing lift, it means to methat there is a LOT of air going over the headers. That air should keep the intake relatively cool when the car is moving, and heat buildup would only be a problem when ithe cars isn't moving or in stop-and-go traffic. One more reason why you should put the GTO front clip on and open up the air exits! Quote Link to comment Share on other sites More sharing options...
