im hoping hes open to making more in the future 
im grinding up the parts for my big block cobalt project (darton sleeves with max overbore and le5 crank, hoping for 2.7 displacement) and want the mp90 to pressurize it! plus its nice that there is at least one other blower available for us. m62 or tvs is a fairly boring spread, if he keeps the mp90 in production long enough it will gather its own following. particularly after i break this **** wide open.

stroked, sleeved with dished pistons and ton of boost 
. its a simple goal really, the worlds most powerful pump-gas supercharged cobalt.
thats the plan. around 8 - 8.5, then beg borrow or steal one of these mp90 kits to load it with air. going to do every other mod to these thats ever been done along the way and then add a few more of my own and with a little luck ill set the record. hoping to keep it to under 20k but its gonna cost whatever its gonna cost.
its all going to be expensive but im going to do it right. ill dyno after this coming round of mods as a baseline, should be around 270 or so then ill start pouring on the cash as see how far i can lift the bar. zzp is going to make quite a bit more off of me than they already have. this round of mods will include all of the bolt ons. then its all about upgrading the motor itself. of course a new trans and lnf axles/hubs will have to go with a stronger clutch after this round but thats to be expected.

5th gen mp112? have you attempted a kit for that yet? or would it be a prototype? if its a prototype ill buy an extra ls4 tb and lower intake and send them out to you so you can mock it up as a complete kit. do you think its worth it to try and find a used m112? i see a few of them for sale on ebay, just a question of whats the closest application to the cobalt to minimize the customization time. my only concern it the bottom of the efficiency map, i know you can spin them too slow to be effective, if the m112 moves so much air that i have to run a underdrive pulley will it still be efficient? the m90 powered a 3.8 without trouble, im just curious if the m112 is too big for its own good.

i know the mp series flows better, but with this big of a blower and this small of a motor, is that as relevant? The m series i could get used for a few hundred, i assume the new mp will cost 10 times as much. if there is no way to take advantage of the extra flow capability is it worth the cash? ill believe you if you say yes, but be honest about it. my budget is big but not unlimited if i can save several thousand and still set the record then thats fine. plus once ive got all the other mods and motor work done, the better blower will be a way to continue to push the bar.

I belive you can get them new from Maggie for under $1500. I got a quote for $1100 when my friend worked there and that was a polished unit. I got a guy who still works there I'll get a price for you tomorrow.

The MP90 needs to have the shorter snout. I was looking at getting one but you have to have the shorter snout or it won't fit. It's all up to you but one thing you have to worry about is that the MP90 is set up for 6 cylinder setups similar to the GTP Grand Prixs so you have to make sure that you build it right or you could damage some stuff.

There is no specific "size" per say. Magnuson offers a assortment of different length snouts.
The MP90 also uses a simple bolt pattern, that could easily be fitted w/ an adapter for most manifold applications.
bolt and tune accordingly, this goes for any setup even the m62.
The MP90 is just a s/c sized at nearly 1.5L
