You'll need a custom intake manifold to mount it on top of the block, a new serpentine belt, as well as an air intake to feed the M90 itself. The manifold is by far the most expensive part of the install. You can either make one yourself if you have access to the tools, or buy one online from a company like lextreme or bullet cars in Australia.

These start at $1990 for people who already got the blower. This is enough if you want just a basic setup running a low boost (7 psi or less). Thst would put you around 350-360 HP at the crank. Going higher requires more depending on what you're running.

7+ psi - New fuel injectors and ecu to keep up with the blower
10+ psi - New transmission, the stock autobox wasn't designed to channel 400+ crank hp
12+ psi - An intercooler would be highly recommended by this point. Personally, I'd opt for one by 8 psi, but you could prob get away without one up to this point.

I don't know of anyone who ran their M90 beyond 12 psi. As far as I can tell, the M90 maxes out around this point. Beyond this, you'd probably be switching over to the M112. From what I've read, its a much better blower for big boost.

I voted turbo for lack of better choices. The M90 is a waste of time. For how much you have to spend for the manifold and supporting mods you might as well go much bigger.

I would suspect a turbo application, though having more potential than the M90, would cost significantly more given the lack of aftermarket support for the 1UZ. As far as I know, there are no turbo kits you can buy for the 1UZ. Consequently all turboed 1UZ's you see out there on youtube and streetfire are custom made, which means you would have to source or fabricate your own exhaust plumbing and intercooler. That's part of the reason why the Eaton superchargers are popular for the 1UZ. Aside from the manifold, they require little in the way of fabrication and the eatons can even fit under the bonnet without requiring an obnoxious looking hood scoop.

Now a turbocharger on an SC300 (2JZ) would be a completely different story. Plenty of support for that.

With an m90 he wouldnīt need to mod the autobox. It doesnīt make too much power to need that.

I don't know if I'd trust the A340E at 10 psi or more. The A650E was rated at 325 rwhp max. I can't imagine the A340E taking much more than that, probably less. By 10 psi, you're hitting well over 300 rwhp. You could probably get away with keeping the stock tranny, but I wouldn't trust it at all if this were a daily driver. The last thing you want is a smoking transmission on your way home from work.

Maybe if this were just a weekend car it wouldn't matter so much. Then again if your SC400 really was just a weekend toy, I'd think the first thing you'd want to rip out is this power-sucking slushbox.

I just think you should go to at least the m112 if you're shelling out the cash for a manifold. You could run low boost on it and save up for a transmission swap/upgrade before increasing the boost, and still have a higher ceiling instead being completely limited by the baby-charger.

It depends on what someone's looking for. M90 is good if you want a fast daily driver. A low 6-7 psi boost would give you a good sub-5 second 0-60 SC400 without having to worry about falling into the modding money pit.

sts turbo setup

To keep the auto safe he only need to ad a transmision oil cooler.
Heīs not going to have more than 200-220rwkw. The autotrans begin to suffer from +300rwkw and thereīs no way to reach that with an m90.

Agreed^^^ The trans is pretty strong with a few little upgrades.

i just got a 5 speed conversion no auto..... is the m112 direct bolt on , will i need manifold that will be hard to find tooo am just worrying about easier set up not power am makin if the m112 is easier set up or less of headache too?

MMCtuner

Ok, so you change the blower...The m112 itīs almost a myth, lol. Iīve never seen one installed on an SC but in a Cobra 1uz maked good gains. Thereīs no way to fit it under the SCīs hood, so you have to modify it a little.
