2G MAS into a 1G

[Marty van den Bosch]

I picked up a used 2G MAS
I picked up part of a 1G wiring harrness to get the igniter plug (perfect fit for the 2G MAS and easier to find - fvaq).
I just moved the one wire in the plug over to match it up.
I picked up a 3" Rubber coupler from Home Depot and shaved the inside diameter a bit on one end for a better fit.




I then got the 1G MAF side plug
A little demel and solder ...



a plate to mate the 1G filter to.
I wanted to remove the can entirely.
I wanted something firm
I wanted something that would be easy to take on/off the filter

A plastic kitchen cutting board!  

Items required:
Demel (ah yes..what a great tool)
4  - bolts with nuts and washer/lock washer
1 - Old air filter (to use for template)
1  - Plastic cutting board from the dollar store.

First I ripped up my old air filter so I could use the base as a template.
I plan on using a clamp system for retention so I want it the same size as the filter's ring.

Second, after cutting it up (notice my nic - oops) I use the 2G MAS gasket as a template for the inner size.

Third - once everything fits snug - I mark then drill out holes for the bolts
NOTE: You will need to countersink the bolt holes so the heads are flush because the filter  patially will sit on them otherwise.



Easy release clamps for air filter.
4 -washers, wingnuts, and eyebolts
I bent the eyeholes into hooks.

And finally - installed !

Was is a bitch to put in? yup  :x



Now I got to figure how to tune the damn thing  :cry:

Costs:
1  - Used 2G MAS  $80~100
1 - Used plug $5
1 - 3" rubber coupler with clamps $10
1 - Plastic cutting board $3
1  - Set nuts, bolts, washers etc.. $5
1 - old filter - free

Total: $100~125

Very interesting method. Can you post more info on this "igniter plug"?

The ignitor (also know as the power transistor) plug on 91-up (or 92-up?) DSMs is the same configuration, though you'll need to pull one of the wires and move it so that it matches up with the MAF.

Oh man - that's classic - I used the exact same coupler and plug as in that VFaq.

Well aren't you just vfaq's poster boy.

good job on that PC power chord thing  that is clever man.

I as well had to do the grinding of the rubber coupler a bit.  Its a tighty

[John Hartman]

pretty cool man

does it fit tho?  My similar setup did not fit, hence I bought a 2g filter adapter for a short filter.

PS Carmen loves that avatar, she was just killin herself a couple of min ago LOL

[Marty van den Bosch]

does it fit tho?

It goes in when the FMIC gets done in a week or so - it will fit then.

I will check though - for anyone that wants to do the same thing. If it does not - I will figure out a work around and post it.

[John Hartman]

yea should be no prob once the upper pipe is outta there.

Now - I need to add a clipping system

This is what I did, I used hose clamps, but modified them, of course....
You probably won't want to do this because I bet you want to run an open filter...  I'm using the (modified) stock can as part of my ram air intake..... see my website for the gory details......

[Marty van den Bosch]

Done!
I put the whole project in one post.
Mods - please delete the empty posts - thanks

I also have a 2g mas in a 1g and they are super long compared to the 1g mas, i also had huge length issues as it looks like in your pic, I had my crammed right up to the uicp.
This weekend I had jordan gladman fab up a 2.5 intake and just make it super short so now I have tons of room.  I'll take a pic tomorrow and post it.
