Anyone put an Eaton M90 on a 4.9?
 
As the title says, has anyone done it or seen one done?
I have a couple M90's, one from a Bonneville ssei, the other from a t-bird s/c.
I know brackets/mounts would need to be made and would be using an intercooler similar to the s/c t-bird. Just wondering the best wat to adapt the piping to the throttlebody and which injectors to go with? Also would a tune be required?
With the stock pulley I would only see around 5psi out of it on the bigger engine but there are pulleys available. That brings up another question, belt routing..........With the limited space the pulleys have what would the best way be to mount the pulleys and route the belt?
Those are just the beginning questions. :confused:

Never seen it...BUT I want to. When I start a one off project I do as much research as possible, sometimes it requires some experimentation with spare parts and adapting what you can find on the market. Good Luck.

So far I have found one guy doing the same thing on a 4.9 that has been swapped into a Fiero. He is midwat through it so Im hoping to see it progress and see how it works.
