Magnus Intake Manifold = PITA

[98TsiAWD]

So I took my intake manny to numerous piping stores, auto parts stores, etc.

And a 1/8" NPT DOES NOT fit the bungs under it for the BOV, FPR, boost guage etc.

Also the bigger 1/4" NPT fitting does fit the other hole, but when I recieved the manifold the threads are all pulled and f'd up.

Then I paid $25 extra to have nitrous bungs put in for the future, marco said he would either include plugs for them or a little note sayign what size they are. He did neither. I have also looked for plugs and there are NONE that fit the ghetto threading job. So I finally got some 8mm metric plugs and decided Ill jsut screw up those bungs I paid $25 for and force them in there if I have too as a last resort.

So, how much HP that bish add??? :laugh:

Sound like you don't have the right tool to install the manifold, or maybe is that you're a tool yourself. Never heard anything bad from Magnus. I believe he tapped the bungs 1/8npt and not all taps are created equal.

Uh, you dunno the concept of a NPT. they are 1/8th NPT on the back and 1/16th for the nitrous if you are running a standard 4 port nozzle.

An NPT thread is tapered. Not all NPT fittings are created the same, some are fat some are skinny they can be out as far as .030" if they tap too much you get no seal and only the fat ones work.

What is most alarming here is not just the fact that there are numerous people that can't identify this, yourself being one of them. The by far most frightening part is that you are going to install this on your car by yourself, AND THEN YOU WILL BE EXPERIMENTING WITH NITROUS.

I can see the headlines now. "4G63 engine shrapnel rains down on Williston North Dakota, dozens injured, magnus intake unaffected"

That's why you should've gotten a forrester

 

[Liquid Illusion]

I had a similar issue with the provisions for the vac nipples on the under side of mine. I just ran a tap across the threads after that the nipples threaded in like butter.

 

[BatmanGSX]

So you couldn't find the right thread pitch at Ace Hardware and then you just tried to force something in? Good job. You are a master mechanic.

See that's why you guys just go out and buy a dejon tool manifold with all the taps and brackets already there

That manifold yeilds nearly the same if not more than the magnus.

Plus it's made of STEEL! JOY!

Do you have proof of this or are you just talking out of your ass to sound cool?

Hey swing lo,

I doubt they'll have identical results. Magnus Intake runs 9's over and over again. And it won't rust. It also doesn't look like it was stick welded by caged undernourished LSD popping monkeys.

For the rest of you DIY'rs
If any of you don't have a 1/8th NPT tap in your toolboxes, (or should I say plastic tacklebox?) you should step away from your tackleboxes with your hands in the air. Also consider paying a professional to work on your car. You should also consider a lobotomy, but thats getting way off topic.

This is the stupidest part. So you're just going to #### your shit up instead of getting the right part? Why? Are you stupid? What exactly is stopping you from getting the correct plugs?

This is just a case of "I'm a moron and don't realize it so it must be the part!" You are a moderator, you should be ashamed of yourself. You are turning your own misadventures into a bad review of a highly respected, widely used and successful part.

Again, I ask: Are you stupid?

The magnus intake made my car faster.

I went to the track 3 weeks ago and beat my fastest time but only by a little bit. I ran previously 12.59 @ 109.55 last weekend I went 12.55 @ 109.75. I know that is not much of an improvement but here is a detail that is not shown. My previous record of 12.59 was with a 1.73 60ft in great conditions. The track 3 weeks ago was wet and cold and my 60ft was 1.83. If I could have pulled my usual low 1.7 60ft time my time would have been a lot faster. I find that 1/10th at the 60ft is 2/10th's down the track on my car. So that would have netted me a 12.3 likely and that is with no other changes. My car was also running a lot richer 3 weeks ago so the tune was not as good and I still went faster with a crappier 60ft.

If my tune was better (like last year) and launch was better I estimate a 3/10th improvement from my mid 12 second time. Thats pretty good IMO. The only change was the manifold from last year and my AFC setting got richer as I didn't have my WB02 in the car to lean it out for the conditions so I was running blind. I know some of you may consider that bench racing however this is my car and I know how it reacts down the track as I spend a lot of time there. I can tell when it's faster and working better as many of us can, and my car is definately faster then before. If I could have pulled a better 60ft it would have been faster.

Magnus though hard to install, is worth it after all is said and done. I could honestly do another one now in my sleep having done it already.

One guy on here has a white 90 gs-t, and he gained 41.7 and 38 lbs of torque. I forgot what his name is, but his manifold is red, and he's in the picture gallery.

I don't believe i have the ability to talk out of my ass, but i will try and figure it out

dejon's won't rust either. I know because i designed the manifold my self, and i have crisco cooking grease incorporated into the steel so that it won't rust

 

[SHicksRUS]

This thread is retarded. "This part sucks because I am too f***ing stupid to understand how to install and use it." I guess by your definition HKS cams are crap too, because if you can't install a Magnus intake you damn sure can't install cams. You are retarded consider killing yourself immediately.

 

[swing lo]

I can make you the manifold with lard instead of crisco grease.

 

[NJGSX96]

So he forgot to put a note in your package about the thread size. So you couldn't find a fitting to fit because you didn't know the size. Did you bother to call Marco to answer any of your questions before you posted about him and completely ####ed up your threads, as ghetto as they were?

So, and correct me if I am wrong, you don't recommend Magnus because you state the threads were wrong, and now even more wrong since you jammed 8mm and 1/4 fitting in them?

Put the manifold down and step away... please.

I put a Forrester intake on my car and while my car hauls ass and went 4MPH and .3 seconds faster down the quarter mile, I didn't bother to check the bolts holding the plenum to the runners and one was loose. I lost it. That Forrester sucks. I don't recommend him at all.

Interesting install methods. I think I found a pic of one of your toys growing up. Tell me if this looks familiar:

I retapped them at my shop using a 1/8" Pipe thread tap. The 1/8" NPT fittings now go in perfect. But may I ask why they werent right in the first place? Why should I have to redo it when its brand new?

Actually I know nothing much about nitrous, hence the PLUGS, Im not using nitrous at this time.
And no Im not a plumber or anything like that, so I didnt know much about NPT fittings.

Thank you for being an mature adult, and posting with a useful post. I already did this tho, and now they thread in like butter like you said. But point being we shouldnt of had to do this.

Nope, Never forced anything in. That is/was a last resort. Now that I have found the nitrous bungs are 1/16" NPT (27 thread) from DSMJim (Who is very helpful and polite)I will find the correct plugs and I may as well buy a 1/16" Pipe thread tap now, since they probly werent done right the first time.

You my friend are a piece of work. I acutally installed HKS cams with absolutely no problems. I assembled a complete 4g63 with no problems.
You are right, installing a magnus intake shouldnt be hard.

Yep the fitting were not tapped correctly, EVERY single one of them had pulled threads in them. I retapped the fitting on the bottom and they are fine now.

The nitrous bungs are another thing, finding a 1/16" tap and plugs is not easy. I have been to about 10 stores today (ranging from auto parts, hydraulic parts, hose and rubber supply stores etc) and none of them have or can get me a 1/16" NPT fitting of any kind.

I have emailed marco, have not gotten a response. Hopefully within a week or so he will get back. I am not going to call, because it costs me almost $10 everytime I call there.

And no I did not force the 8mm plugs into there, last resort option if I cant find 1/16" NPT plugs, but I have now found some on summitracing.com for about $8 each
