Ok, i got ahold of an M90 off ebay for about 220 shipped.
For the people interested in making their own gasket fairly easily instead of using liquid gasket, or whatever that stuff is, here is a small writeup type thing on it.

First i took a piece of paper and taped it in four sections over where i wanted the gasket to fit and shade over it with a pencil, doing so will expose the edges (see pic):

Next, you cut out the shape of the gasket from the paper, and tape it down to your gasket material... (i chose 1/8" cork gasket). Once you have it taped down, you can trace it out.

After you have it traced out on the gasket material, go ahead and cut it out with scisors but be very careful because it can be quite delicate, she used a razor blade to cut out the center piece. afterward spread a film layer of gasket sealant stuff (its in a tube, i forget what its called) on the CLEAN surface where youre going to lay the gasket you cut out. and lay the gasket down carefully and lined up.

Spread another thin layer on top of the gasket and place your custom inlet or outlet piping onto the gasket, bolt it down (i should have used lock-washers.. oh well) and youre done!

 

I apologize for the bigass pictures..

 

So are you going to follow zbrown's location or are you trying someplace else?

 

Well, I found out there is no way to mount it on the drivers side.. There plain and simple isnt enough room, the eaton m90 is a larger unit that i thought..
Im going to mount it on the passenger side, but with the outlet (on top) facing the TB instead of the hood, like zbrown did...

 

That cork gasket stuff isn't nearly as good at sealing as using silicone to make a gasket.
A while ago I was doing a similar thing to my ae86 and had to make a gasket, tried the cork **** first, but quickly realised to use silicone after vacume leak started popping up there every day..

Would HATE to see what it would be like under boost..

So, more power to you if it works good, just a word of caution here, make sure you don't over tighten the plate onto it aswell or else the stuff just plain falls appart.

 

You know, I was actually concerned with this.. i was like "damn, this is kinda fragile" but ill try it and see what happens.. well i might.. I dont wanna do a halfass job on this project so i might change it.. still before i put it on.. thanks for the input

 

Dezerte, do you still have power steering?

 

is it just me or does your little adapter plate look a little bowed and not quite sitting flat?

 

Nah, you are not the only one. I saw that too, but I thought since it was late and I have been working that my eyes were trying to play tricks on me.

 

Nope. No AC either, i dont have a lot of things view my sig

 

Its actually very straight.. it looks like that because some of that brown sealant stuff oozed out a little bit before it dried and it just looks like that. I might just remove it and use a different material

 

No PS or AC... Hmm... and still not enough room to put in on the drivers side? I have yet to get my hands on a m90, but I plan on looking for one at an auto swap tomorrow. I really want to get a supercharger on that side, there is just so much space there.

 

what is up with the square? shouldn't you at least grind it out to make it flow better?

and if I actually do this, I will be making mine with a raised top.... yes it will take longer, but I also think that it will flow much, much better. I also think I will be using larger diameter piping...

 

That son of a bitch is pretty big.. if you put it upright, it wont fit on the drivers side at all, unless you put it sideways, which i might to, doing this would allow me to easily fab a FMIC.. well at least easier than if it were on the passenger.. and yeah, youre right about the square, Ill probably use the nitrade reamer drill bit and ream it out.. The diameter of the piping is 3".. I donno if you would want any larger for that... Thanks for all the comments/suggestions/criticizm i apriciate them muchly, so far i plan to grind the sqare out , and change the gasket.

 

mmm... well what I see is that there is air coming out of the supercharger port, slamming into your adapter, and taking a sharp 90 degree turn. your s/c is going to end up working harder than it needs to, thus resulting in parasitic losses. my goal would be simply to try and have the air maintain as linear a path as possible. I understand the room concerns... I guess I'll have to wait till its my turn and find out for myself. I'll be waiting for a 94+ supercharger though

 

Yeah, Thats why if i was going to mount mine on the passenger side i was going to mount the SC sideways, so it would run straight into the TB and avoid the 90* turn

 

Can't you make the outlet a bit of a smoother transition?

 

Cork + Boost? Not going to work. Even if you silcone both sides, it's still going to blow out.

The metal that you used for the flange is also WAY TO THIN! What is that? 16 gauge sheet metal??? The whole adapter is going to flex.

 

Lol, how am i supposed to know it would warp, im a lowly NA owner
Thanks for pointing it out.. ill just totally redo it all with different material.. What kind of gasket/sealing would you suggest?

 

You people who want to put it on the driver side are forgetting two things.

A) Oil filter
B) spark plugs

For how often these two need to be changed, do you really want to have to unbolt the supercharger, remove it, replace either of the above, then bolt everything back up?


Oh, and also, get a die grinder or something and grind the rest of that metal square out of there. Make it match the I.D. of the pipe coming off, it'll flow better.

 

i Totally redid the whole thing, ill post pictures tomorrow

 

Keep up the great work bro. PROPS!!!

 

All the posts about the girl in the pictures have been deleted. Get a life, guys. Any others will be deleted as well...

As for the real subject of the thread, two observations:

1. The flange is way too thin. You'll need at least 4MM to make a good seal. For a part that wide, 5 to 6MM is best.

2. The pipe is quite small, and doesn't have a smooth transition to the flange.

Other then that, cool.

 

I'm not so sure that cork couldn't work in that kind of application. I've worked with transformers that were pressurized more than you will boost sealed in a similar manner. The difference is that they used 1/4" or 3/8" cork to help withstand the pressure. They get pretty warm too, but I suppose perhaps not as warm as in your application.

This whole DIY supercharged N/A is a cool trend that has started.

Why am I not shocked that people made those kinds of posts?
