The link for Richmond says VVTi but there is no details for any other manifold. The system they have sold is for the NON VVTi engines specifically 1990-1997. Intakes are NOT interchangeable between the early and the VVTi years. I would make certain to comfirm fitment for 1998+ engines before importing the kit.

I would also like to hear from any of the super/turbocharged members with regards to their fueling requirements. Member ScottURnot reports running 6psi SAFELY on his supercharged 1997 SC400 with NO fuel system modifications whatsoever Does ANYBODY know what the VVTi system does when boost is added? Can the system correctly sense added airflow (boost) and add the required fuel up to a point? Is this only something the 90-97 MY did? Any experience here chime in please.

^^ non vvti as well... I remember someone emailing them years ago and they said they were working on one for vvti. I wonder what happened??

The Bullet manifold is also for the non-VVTi motor, I've talked with the guy a few times. 1UZs are popular in Australia, not 1UZs with VVTi heads...

Notice the kits contents, though...a supercharger, intake manifold box, custom intake, gaskets, yadda yadda yadda. We could do that.

Not from me...car's for sale. Supercharger's for sale, too. If I was keeping the car, though, I'd have this wrapped up already! This would be a sweet project!

I think PASNU (Mike) is selling his supercharger. The same one I have.

Please post a picture of the inlet of this supercharger. Did the seller say it was from a 89-93 SuperCoupe or (94-95). The price tells me you got a 89-93.

Also note that the SuperCoupe superchargers don't have a built in bypass valve, so you will have to add one yourself. Just remember when you create your own bypass that air must be recirculated in front of the blower and behind the air flow sensor.

If you want a extreme custom aftermarket M90 case you can use the GTP rotors and put them inside this case:

I was able to get 350 rwhp out of one of these on a Ford pushrod 3.8 V6.

A couple of things to consider:

Don't bother with a hybrid M90/M112, it will never work. I've seen one and saw it in action, it never lived up to the hype and it's sitting on a shelf.

On a Ford pushrod 3.8 V6 with almost every available MOD for that car including a big billet cam and ported, polished and big valves. A 89-93 ported SuperCoupe supercharger could only put out 290 rwhp. Car was switched to a MPx (from link above) and it jumped to 350 rwhp with a 2 psi jump in boost. What you guys need to consider is the M90 stopped being able to feed my 3.8 by 3500 rpms and torque started falling, peak power was made at 5200 because the M90 couldn't feed it enough air. This car then was switched to a 1.7L twin screw and it made 403 rwhp at 5200 and was now limited by the valve train and stock bottom end. Torque was over 400 by 2500 and stayed above 400 past 5000 rpms. This blower on other SuperCoupe has made 470 rwhp.


In a nutshell I believe a M90 will give the GS400 a lot more low end torque but by 5000 it will starve the motor and there will be very little gains in power.

I still have concerns on hood clearance as a M90 can also bubble paint when to close to the hood.

Well its been a while since this thing was posted, & I just saw that someone posted yesterday about being interested. If you go throught the thread there is a email address, to me this is the way to go, if your gonna do a roots blower. Oh and the 3uz is the same as the 1uz vvti. OK. thats why I have the 3uz block. Only difference it the bore size.
