Question about M90 intake manifolds

[CNCguy]

Would people be interested in buying an intake manifold that would allow a M90 to be bolted to a 3X00 with 3500 heads? The highest point is about 4.5 inches above the top of the valve covers. You would have to add about 1.5 to 2" to that if you want an intercooler. The PS pump would have to be removed or relocated and a new fuel rail would be required. I am estimating that a swap kit would be somewhere between $800 ~ $1500 without the SC, intercooler or tuning.

This is in the very early stages of development but don't want to waste my time if there would not be enough interest.

Marc -
I am very interested, let me know if there is anything I can help you with.

The only problem that I see is hood clearance. Is possible to create a very low profile LIM to give some additional clearance?

Will do Phil.... As shown is about 1.5" taller than a '95 3100 intake. It may be able to go a little lower but it will make it more difficult to get the injectors in. I have a way around it I think but it would require new valve covers and add more to the cost.

I plan to make a billet prototype early next year for myself and will proceed from there if there seems to be a demand.

wish i had a car for that, i would buy it in a heartbeat. maybe to apeal to the fiero crowd, you could make the brackets to mount the m90 above and beside the aft (left hand if viewed from pully side, or 'trunk side' on fiero) valve cover. make a new bracket to move the alt. down a bit, and a piece to bolt on the chargers outlet with a pipe exit for routing to intake mani, or intercooler to intake mani.
may not be something your interested in, but you could offer your hardware cheap, make no provisions for a kit of any sort, just mounting brackets and lower supercharger peice. then the buyers could get thier own m90, proper pulley, and engine management. could be some quick cash and help out a whole other world of the 660's.

I would be interested but I would be more interested in headers/downpipe etc for a turbo kit.

[merlot566jka]

looks like this is going the wrong direction, sorry to get off topic. i say build it and they will come.

[Young Whitey]

I agree, this kit would sell.

[ihatemygrandamg]

Maybe in the future I would be interested. My grand am is my daily now but with 132k miles, in another year or so when I turn 18 I plan to take it off the road and make it a race car(lol thats not something you see everday). But yea Id be interested if its for the 3500 heads cause Im gonna be doing the 3500 swap when I get a new motor.

So what all would be included in the kit?

[montess408]

cool set up man any way to get it done on a 3.1L mpfi gen2 ??

[SappySE107]

Yeah, swap the 3500 top end on it:P Thats the best route to go anyway.

[Azrael]

I can understand wanting to use an M90 since they're used everywhere but if clearance is an issue why not use a slightly smaller supercharger? An M62 is supposedly sufficient up to 4L engines and will save 0.4" vertically in this setup.

The cost of development and tooling are high so I figured that if it only fits one style, it should be the 3500 heads. They are the best flowing and will fit older engines.

The T-bird SC M90s are cheap, plentiful and are more effecient than the M62s. But, with the manifold design that I am planning will have a seperate top plate. This would allow addition of an intercooler, moving location of blower for pulley setup (FWD/RWD), possibly a M62 to fit, etc.

[kflo 93 gt]

This would really encourage me to build a hybrid. I could deal with having a 2" cowl hood to clear a supercharger. I can't deal with it killing my view of the road though. What kind of timeline would be on this do you think? This would also eliminate the need to getting 3500 upper manifolds, I'd only have to source the heads then.

I think this is pretty kick ass. I'd love to see it go through.

[bszopi]

If how it sits right now is only 1.5" above the height of a standard 3100 plenum, then it would only pop through the hood (of a Beretta) 0.5". When I had my 1" spacers on my 3100, the plenum hit the hood (and pushed it up slightly due to the sound-proofing ont he hood), so any cowl used to "hide" the SC would be minimal.

Oh, and Marc, if you need any help on the CAD side of things, let me know. I am actually looking into a way to be able to embed a DWF veiwer into a site page for all the current CAD files I have on the side, and hope to start making more files soon. I am just now wrapping up a week in Las Vegas for an Autodesk (aka AutoCAD for those that don't know) convention, so I've learned a few things that I want to try to put to use.
