Guest DatsuNoob Posted April 27, 2007 Report Share Posted April 27, 2007 I was checking out the intake manifold I got from Slodat yesterday, and comparing it to the one Hainz gave me. Looking inside of the ports, Hainz's one has 2 channels that run down the #2 and #3 ports, Slodat's is smooth and plain inside just like the other ports, none of those channels. What's the difference. Does one perform better than the other? Quote Link to comment
71-521 Posted April 27, 2007 Report Share Posted April 27, 2007 Hmmm, I just went and had to look at mine to try and see what you're talking about....can you post a picture? Quote Link to comment
slodat Posted April 27, 2007 Report Share Posted April 27, 2007 I have the pimp shit Nooooob :) Glad you got it!! Quote Link to comment
Guest DatsuNoob Posted April 27, 2007 Report Share Posted April 27, 2007 I'll try and get some pics on here later tonight, but one of them has two curved troughs that run from where the carb dumps in all the way to the openings of the intake ports. Kinda weird, I dont know what they would be for. Quote Link to comment
]2eDeYe Posted April 27, 2007 Report Share Posted April 27, 2007 My L16 intake had those as well. Not sure what the purpose was though... Quote Link to comment

Guest DatsuNoob Posted April 28, 2007 Report Share Posted April 28, 2007 I think it was designed to create a swirling effect on the incoming atomized fuel, who knows for sure, but I like it so I decided to use that one. Quote Link to comment
Guest DatsuNoob Posted May 6, 2007 Report Share Posted May 6, 2007 here's a couple pics for those of you wondering what the hell I was talking about. Quote Link to comment
datzenmike Posted May 22, 2007 Report Share Posted May 22, 2007 Today I started to pull my part '78 truck L20B apart (internet down, funny I get more work done when that happens, I wonder...) anyway, the intake has these grooves running along the bottom of the runner too. But, it's only on the front #1 and #2 cylinders. Makes no sense at all. Quote Link to comment
Bleach Posted May 22, 2007 Report Share Posted May 22, 2007 my L16 manifold had that too.... and I ported it as well. :) In fact, I think I still have it. They are power channels. Quote Link to comment
Guest DatsuNoob Posted May 22, 2007 Report Share Posted May 22, 2007 Do you mean #1 and #3 intake ports? Quote Link to comment
OL YELLER Posted May 22, 2007 Report Share Posted May 22, 2007 my L16 manifold had that too.... and I ported it as well. :)In fact, I think I still have it. They are power channels. POWER CHANNELS? for a 95 HP engine?..um yeah! LOL wonder if it would help to atomize the incoming gases...but why only two ports?..hmmmmmm where is the Japanese engineer when you need him?

lynchfourtwenty Posted May 23, 2007 Report Share Posted May 23, 2007 no kiddin huh ron .. try changin the oil filter on a 92 nissan sentra se-r .. its a nightmare gettin my hand in there and the little "tool" dont even fit down there i have to stab a screw driver all the way through it to brake it loose.. gettin it back on is a little easier you just take that screw driver and... LOL just kiddin but ya gettin it on is easier i dont know why.. it would be lovely to know a japanese engineer to perform these tasks for me.. an maybe explain some of the werid stuff they've done to these vehicles LOL Quote Link to comment

lynchfourtwenty Posted May 24, 2007 Report Share Posted May 24, 2007 was it the se-r tho... the sr20de they crammed in there barley fits .. very tight sqeeze to get to some stuff.. i'd imagine the ga16e would be much eaiser Quote Link to comment

Or theirs are normal and ours are like baseball mits. Quote Link to comment
datzenmike Posted May 24, 2007 Report Share Posted May 24, 2007 Seriously though, I find the engineering top notch on almost everything. Just take a look at how easy it is to fix and maintain a 620. Now just try to find an equivilent N AM piece of junk that simple. There's dozens of examples of crap that should NEVER have 'hit' the road. Don't get me started. I cringe every time one passes me.

Llittle_Llama Posted April 26, 2008 Report Share Posted April 26, 2008 so his anyone ever find out exactly what they are and there function? i know this is an old as shit post, but mine will be here in a few days and im sure imma get stuck with the trough one :mad: so could you weld them full?

makya Posted April 26, 2008 Report Share Posted April 26, 2008 I don't know what they're for,but mine has them too. Quote Link to comment
datzenmike Posted April 27, 2008 Report Share Posted April 27, 2008 I have an early L20B '75 truck I think. I has both manifolds joined and has a heat riser and valve. There are no holes for water from the head and does not have these grooves. This manifold is from a '78 620 auto and has them on the front two cylinders only. Further in the metal is thiner between the water passage and the groove. Maybe it has something to do with intake warming. But why warm the front two. Maybe the front two get more cold air blown on them by the fan on cold days and run cooler? http://i138.photobucket.com/albums/q251/datzenmike/wreckingyard2608052.jpg[/img]"] They join and continue to the first bend before the carb. http://i138.photobucket.com/albums/q251/datzenmike/wreckingyard2608054.jpg[/img]"] Quote Link to comment
Llittle_Llama Posted April 27, 2008 Report Share Posted April 27, 2008 someone should bench flow these things, lol Quote Link to comment
