Magnus SMIM Install Question

[SFRacingGST]

1: There was a ground on my factory 2g intake that connects to the wiring harness. Can that go on the firewall or does that need to be grounded to a screw on the intake?

2: Will any civic battery work or is there a specific year i have to buy? Any other batteries work? Does it have to have a minimum amount of cranking amps?

The fire wall should be fine.

The civic battery I bought was I believe from something like a 95 civic. It was simply the smallest one the local auto parts store had. Its alot skinnier and slightly taller. It doesn't have as many CCA's as the stock size battery nor the capacity so it is easier to kill but its still enough to start the car on cold days.

What ground wire are you talking about? I just installed my Magnus 2 weeks ago, and I don't remember seeing any ground that attached to the stock IM.

Got a picture?

he is referring to the ground wire which is located near the purge soliends for emissions on 2g's. one side of the cable is bolted to the firewall and the other end is bolted to the throttle cable bracket on the bacc of the intake manifold.

I'm familiar with that one, but in the OP's first post, he makes it clear that it's a ground wire coming from the main harness and grounds to the intake manifold. I'm not familiar with such a wire.

I will take a pic later on when i go an work on it at the garage, but the wire was coming from the main harness (the same with the injector plugs, coil plug etc) and it has one small clip and then a wire going to the intake where its connected by a bolt.

didn't work on it tonight, but i will get one tommrrow. I have another question. How should i route my vacuum lines? I know the brake booster to the big fitting and the other three should have the fpr, boost guage and bov on it however where should the boost controler (greddy b spec) and tial 38mm wastegate go?

Brake booster, FPR, BOV, and boost gauge.

Use the turbo's compressor housing for a pressure source for the wastegate. Remove the cover, drill and tap, and install a hose barb fitting.

hmmm, is there anyother way of hooking it all up? i installed the turbo already and really do feel like pulling it again and buying new gaskets, please let me know what my best bet is

Hi,

Im not too familiar with 2g's but maybe there is a fitting on the intercooler pipe right after the turbo. Like on 1g's there is a nipple on the J-Pipe that you can use.

heres a pic of that ground i don't know where to hook up, you think the fire wall would be fine?

Do you have a downward firing turbo?

As far as I knew, that was just a noise canceling device. As far as I knew, it didn't even need to be grounded. I have mine just dangling down below the SMIM.

 

[SFRacingGST]

yes, it is a downward facing turbo (green), I guess i could stuff a rag up it and drill out the hole and tap it and then put a nipple on it, but i just wanted to see if i could use the intercooler pipe instead or something like that. please let me know what the best thing i should do. if the performance is going to be the exact same i am thinking id rather go to the ic pipe.

 

[Mike1992]

Sorry to kinda steal from this thread, but I'm working on a 98 gs-t and when I went to unplug that noise filter thing the wire pulled out of it. Could I just jam it back inside or should I buy a new one for the guy???

Being that it is downward firing, you can just drill and tap and all of the metal chips will fall straight down and out. No rag required. It might be a PITA to get in there with the turbo installed though.

You could also use the IC piping. It will perform the same. Just put the fitting close to the turbo and make sure it's sealed well.


Here's a picture of the fitting I installed on my previous turbo:

thanks for all the help! decided im just gonna run it off the lower IC pipe as close to the turbo as possible. This way i can auctally take the pipe off and not have to drill a hole in my turbo. wouldn't the pressure be the same where im going to drill it than at the turbo? thanks again. Hopefully starting it up this weekend

Privided there is no leaks -Yes, it will be the same.

IC pipe will work fine, like Paul said just try & get it close to the turbo for best response. I've run it in the lower IC pipe with my T25, in the jpipe with my evoIII & currently have the comp housing tapped on my 3052 & they all worked great. One thing to note if you are using the IC pipe, most are fairly thin walled pipeing & being round you may not be able to get a proper thread if you use a 1/4" NPT tapp. For this location & the size of barb you need, a 1/8" NPT would be the better route to go.

Or better yet - weld a bung in place.

Hey gstracer, did u run your wiring harness over or under the magnus? Mines over right now but i want to try to put it under for aesthetics.

Mine is Zip-tied to the bottom of the fuel rail...can't even see it.

When I installed my barbed fitting into the jpipe, I did silver solder (1800F) it in place as well Also tested it to 50 psi or so just to be on the safe side

Mine is over the manifold as well. I wanted it underneath, but I don't think I'm going to want to hack up the injector wiring to extend them to be long enough. Mine is currently tucked underneath the fuel rail like Ty mentioned, and it looks fine.

Back to the hose barb.
I just drilled and tapped my buddies J-Pipe on his brand new ETS 1g street kit.
I used an 1/8" NPT tap, and some JB Weld.
I started a couple of threads, mixed up the JB Weld, applied a little bead all around the fitting right at the pipe, and then threaded the fitting in til it was nice and tight.
It turned out perfect, and it will never come off.

 

[SFRacingGST]

cool, hopefully i will be finalizing things today. Another question i had was regarding checking my timing with a coil on plug, how would i go about doing this with out a wire to hook the light to?
