I'd do it, but I've already given my 4-cyl to my dad. How much time would you need to measure, etc.?

Benzito I have talked with you in private about the supercharger.

I have an Eaton M90 3rd gen as I told you but I have a 1992 with EGR and Air Pump so this leaves a bit of a question. Now I have studied up on dimensions differences and now im thinking the M90 may not fit at all.

M45 dimensions
Eaton M45 3rd gen.

13 in long and 4.8" high and 7" wide. Would you say these are the proper dimensions of your specific SC?

now here are the M90 dimensions.

Eaton M90 3rd gen.

16.4 inches long 5.5 in high 8.1 inches wide.

What do you think too big?



Also, how did you make your gaskets or do you not have any gaskets? I figure I need gaskets between the inlet to the SC and the outlet to the sc then another one for the throttle body. Do you know of a company that can do cutsom metal work or can your friend do it? Id be willing ot pay up to $1000 for the custom parts I need, maybe more if they are all to specification.

In other words in need the Mounts the flange and manifold for the intake to the SC and the outlet and the throttle body connection. I can get my own pipes and bypass valve.

Cant wait to see the pics

I am contemplating an Eaton M62 for my '90 M104. Did you guys get rid of the air pump to mount the SC or did you mount it next to the pump? It is hard to see on the pictures you posted.

Thanks for the info.

HZach;

On my install the SMOG pump was removed to make way for the blower. The install was a lot easer with it out of the way. This factory air pump only runs a very small percentage of the time anyway and it is certainly not missed.

I've got some high resolution photos of the blower placement; if you want them send me an email address than can handle a few Mb.

Sorry about the delay guys, been a busy week... anyhow. I honestly think the m90 is WAY to big in displacement if not size. It's more suited for v8's over 4.5 liters (for example,m they use it on the 5.4L lightning motor). An m45 is working great for performance increase and better overall drivability plus it's easy on gas milage in normal operation and easy on the stock FI system. The m62 could fit and would probably work well on a stronger m103 builup with some more major fuel system mods and would probably actually be better suited to the 3.2L m104 mills. I just custom-cut some autozone gasket paper and topped it with some RTV sealant. As for fabrication, if I can find time, I've become pretty good at fabrication work and I could probably make a bracket for a fair price (mine took out about $50-60 in materials includeing the idler on a high guess and took me a couple evenings to really get it all lined up properly. So maybe $250 altogether sound fair for the mounting bracketry?). I could do it pretty quickly if you're willing to go for the same sc that I have (an eaton m45 off an earlier c230k). That way I could just copy my bracket. Mine set me back $220 for the unit and about $25 for the rear rotor bearings shipped. My car never had a smog pump (go 1989!), or egr for that matter, so that left a big fat hole next to my engine that fit the c230k unit perfectly. It would still fit fine on newer models, but you'd have to remove the smog pump and idler.

People have had success with the air-to-water intercoolers off a GM Typhoon and using a Mercedes/Bosch auxiliary water-pump.
