Just want to know how compatible one would be on a non vvti 2jz...and if it is, your thoughts on adding one

 

I think it should fit the jz but not sure how it will fit under the hood.

 

You could always cut a hole in the hood and go Corvette ZR-1 style.

 

its good to think out the box, but why would you go through the hassle of S/Cn a SC300, maybe the SC400

 

just do it......... try somthin new

 

I have the same ride bro it sounds like a good idea

 

I've always wondered if anyone has supercharged the 2JZ..

Well I understand the benefits of going turbo rather than sc, but I don't plan on going crazy trying to make power. I was thinking a stock is blower would give me enough oompf to make the car get out of Its own way.

 

Why does no one here have faith, or understanding, that a belt/gear driven supercharger, at proper size inlet,runner,turbine pitch and total rpm range of the charger matched to the engines needs for its final intended purpose....breathe,.....can equally perform with a turbo or NO2 car. If you know what you are doing, then you can have tons of fun....and plenty of BOTTOM END TORQUE, which is not found in a lot of "turbo" cars that have lag and or peaky powerbands. I have owned centrifugal charger cars , granted neither were 2jz powered,but both rides were dramatically for daily drivers....so they sat and were driven on the weekends,or to work 2x a month. NOW...THE REASON I CAME HERE IN THE FIRST PLACE!.....I really thought someone would have blown a jz and had good things to say. Something smaller than a vortec V1 or ProCharger p1, as both of those I have ran with MAD LOVE on my 347" 94' SN95 mustang and 91' S-10 383" truck. Bothers were very tame,hardly even cam swap from stock,air conditioning, and W/O the need for intercooler even, due to 8.95: 1 C/R on both engines.AND TO MAKE MYSELF ABSOLUTELY CLEAR: I would never expect a 93 octane pump gas 10.5:12jz VVTI to see more than 6-8 psi on stock internals, Intercooler and all, and make even closethe 452hp/472 tq that the mustang had at 10.5 psi..........BUT AROUND A REAL WORLD 275-300 IS DO-ABLE with computer wiped and properly tuned, especially the ignorance timing drawback is a must.
So------ Anyone done a centri-charger 2j out there????????

 

I've seen (and driven) a GS300 with a supercharger. One of the old CL guys had one. It wasn't particularly fast at the time. It was probably in 2003/4. I don't remember what brand or specifications it was, but it's been done.

 

I've seen pics of at least 2 SC's that adapted the centrifugal IS300 kit to work. The only issues people had was the engine management for the IS kits is incompatible with the SC300, so you have to go full standalone.
All supercharger kits for the IS300 have been discontinued since 2009. All the known manufacturers either discontinued them due to low sales, or have switched over to making turbo kits.

There is one company I know of that still makes a supercharger for the 2JZ-GE motor. KS-Auto out of Japan. About 2 years ago, this little know japanese used car dealer / amateur racing shop came out with a HKS Rotrex - based bolt-on kit for the non turbo MKIV Supra.

 

I have seen them on plenty of IS300's the main difference on that side of the engine would be distributor clearance but shouldn't be that much of an issue.
Centrifugal superchargers do not make large amounts of boost instantly like you think of a traditional supercharger, but can be more responsive than a turbo, but also make alot less power up top vs a turbo.

reason why lots don't do it cause the 2JZ has no problem spooling a turbo that will provide more airflow than one of those can do, but if you are looking for a lower power more torquey setup then yeah give it a shot it will likely work and has been done before.

 

The supercharger is unique but it will be a lot of work for limited results. If it's the specific experience that is desired and the cost and custom work isn't of concern then it's probably going to be a good fit for the right owner. But I think there are fewer of those folks than there are folks who want a turbo engine. An easier alternative for lots of torque way down low is a 1JZ VVT-i swap. 280 ft-lbs of torque @ 2400RPM with the stock turbo at stock boost and room to go up to 450-500whp without too much additional investment. Or any 2JZGTE with the stock twins (significant torque starting at 1,800 RPM).

But then, a small modern ball-bearing turbo on an NA-T setup can probably spool very quickly as well.

 

THIS^^

Although you might see psi numbers sooner on a overspun centrifugal blower, it will never make torque as quickly as a small turbo setup. Don't forget it takes HP to make HP on a supercharged car. It's almost entirely 'free' on a turbo car since there is no parasitic losses on the crankshaft.




Roots blowers are a different discussion..
