Supercharging a 1UZ
For anybody who is thinking about supercharging a 1UZ
I wanted to point out a few things you will need. The stock 1uz ECU can handle up to 12lbs of boost which is much more than you would be getting from the typical M90/M112 roots blower. There is a lot of talk about the M90, but for the money and time, you are wasting it all doing an M90. M112 is the only way to go for a roots blower on a 1uz. It should yield around 6lbs of boost at most without getting into the heavy costing items. What I am going with.
1. M112 from mustang cobra. Some people used lightning m112, which should be the same, but the snout length is different on certain m112 blowers and I know for sure the cobra will work.
2. Lower intake manfold to take the M112. I am having mine made by a guy in canada who is very good at this. I found him on lextreme. He has to moddify the lower intake, fuel rail, and front water bridge. The supercharger will fit nice and low on the motor.
3. Larger fuel injetors. Some have run the factory 1uz injectors, but I would never do that as if it ever leaned out to much, you have predonations and potential serious problems. I used 7mge non turbo supra injectors, which are 315cc in size
4. water/methanol kit. Heat is very bad, and without an intercooler system, the air needs to be cooled. Water/Meth is a cheap and reliable way to cool the air. I am, at this piont, going with an AEM kit.
In total, my supercharger cost will be roughly 1600 in parts, plus whatever my machinest charges to modify the M112 to work. All in all, a very worthwhile cost to add 100rwhp and such a sexy sound to your vehicle.
