Question about M90 intake manifolds

[geldartb]

You can always do it the ghetto way, like that beretta had. The plenum was machined down, and an adapter plate was made to fit the SC, then welded the plate to the plenum that was machined.

that would be this guy who did it. mcgavinz26 a few posts up.

if i had a spare hood id be all over it since i got an m90 in my garage.

In a fiero you may as well put the supercharger right on top of the intake. Thats what my plan is eventually, once I find a fiero at the right price. My intake will bolt right onto your fiero if you want to try it out. You have to promise to give it back in one peice when you are done though

Seriously though, I've looked at it a lot too and there no low profile way to get an M62/90 on top of that engine while using the original lower intake manifold.

I don't think there is a way to machine a one peice intake, or even two peice, to replace the whole intake. That would end up being pretty pricey anyways.

Anything you do that moves the injectors from pointing at back of the valves would be a hit to your performance, but probably not much as long as you didn't switch to some sort of tbi (gross).

The only thing that miiiiight work is hacking up a LIM and turning the part where all the runners criss cross into a plenum of sorts and welding/machining something up there. I have no idea how you would cram injectors in the mix with that though. Then you still need to relocate the power steering pump and do something about the couple inches you need on the hood.

As far as the PS pump goes, you can eliminate it and try a Honda electric hydrolic steering pump. Thought the 3500 cars came with them too.

If you are super or turbo charging a car, the P/S pump relocation should be a simple fix

I'm interested in the electric pump, do you know what cars they came in? I don't have enough room to comfotably fit forward facing headers, A/C, and P/S -- the A/C is staying regardless. The fbody has a funky kmember location in comparison to the engine.

I would like an M90 please.

I'm not too concerned with clearance in my Isuzu so I'm all for the weld-atop-3400 style, if it works.

so is it safe to say that this wouldnt work on a 3900 lz9? ive been dying to sc or turbo my car
