Factory Supercharger Is Available

Ridgemanron · 2004-04-30

Re: May, 04 issue of EVO (Pg.28) In this article centering on the Exige it's mentioned that "Toyota already offers a factory-approved supercharger kit for the (Exige/Elise) engine."

Toyota is planning to cash in on its F1 programme with an AMG-style tuning operation that is creating a range of performance-enhancing engine kits. Developed by Toyota Motorsport in Germany all products will come with a full factory warranty and service back-up in the UK. Among the kits going on sale before the end of the year maybe sooner is a Supercharger for the 1.8l 2G-ZZengine Corolla T-Sport. Running a Roots-style blower from Japanese firm Ogura, it bumps power from 192BHP to a Honda Intrgra Type-R beating 228BHPat 7800RPM. Torque increases from 133lb to 184lb at 3900RPM. 0-62 Times will be improved to around a low 6secs despite the retention of the standard cars's gearbox. Top speed will rise to inexcess of 150 MPH.

here's the thread. It was on the hotly debated "spotted SC Elise in Miami," if you guys remember.

I'm not sure, It says that the kit will be available by the end of this year.

I have no doubt, that Lotus will use this SC for exige/elise. My guess is that this SC will be adapted for the elise/exige by the end of this year also. If Lotus installs it, it will obviously come with a factory warranty. I don't think Toyota will install it because Lotus did make adjustments to the engine to increase power/ECU.

Well I would for sure forego big HP numbers via aftermarket if I could get this mild SC done under warranty. I think 230hp would keep me real happy not to mention the healthy torque increase. I'm starting to feel exhausted in how bad I want this car. The nice weather is making it even worse.

i agree with you on both counts. maybe 240 hp

Then you work on reducing the weight a 100 lbs or so!

Maybe 240-255hp. Just a rumor.

oh yeah? That's a good range. If we can achieve a power to weight ratio of ~7.5, I think we will be in awesome shape.

2004 Z06 has a ratio of 7.7 (3116 lbs / 405 hp)

Please clarify: HP is a rumor or SC is a rumor?

He is refering to the rumor that the SC actually will put out 240hp-255hp... Now that would be really dangerous combo against anything. I have driven a light weight car with that power to weight ratio, and all I can say is acceleration feels like a fast sport bike rather then a sports car.. The fun factor is way off the charts

Any guess-timate on what an installed supercharger would cost with Lotus doing it? The 'Works' SC by Mini comes with suspension and exhaust upgrades
that are defined at $4,500 for parts, roughly $7,000 installed.

You can't really compare that. The Works package is added to a car that is already supercharged from the factory. It must be much easier to replace the supercharger on a car that already had one than add one to a car that was normally aspirated.

don't forget that the Works package also includes a new exhaust, and a new head. Of course you also get a new supercharger, but the head has to be expensive. I have seen SC kits from $1,500 to $4,000. Usually they are not that hard to install, especially compared to a turbo kit. I would think that if TRD produces it, and we all know that the Celica is a relativly cheap car, that they could not offer the kit for a lot of money. I think that this will be good for the Elise, as the ECU will be one of only a few parts that would have to be different, assuming that that it fits in the engine bay!!!

This would be great if it is ever developed, and if we could get some more information! Of course if any companies plan on offering something like this, it owuld be great if they said something too!!!

Not to further the hijack, but the Works kit unfortunately does not provide any suspension or brake upgrades.

The new SC installed is basically the same as the stock one (there is a debate about different coatings on the SC fins) but it has a 15% smaller diameter pulley. BMW just decided that it was easier for them to swap the whole SC rather than swap the interference fit pulley.

The head change offers little real improvement since they don't upgrade the intake or the throttle body. All in all it's a very expensive upgrade where you're paying more for the continuation of the warranty rather than the pure performance improvements. As such, it's probably a better option for most consumers who don't like to "mod" their daily drivers but still want a little extra kick.

As for the Elise SC, I will enjoy my car immensely and drive it stock until I see more real options for making improvements come on the market. No hurry here, it's more car as it is than I've ever driven before and by the time I get comfortable with what it can do I'll look into kicking it up a notch.

The SC used by AMG for tuning the Mercedes 500 SL is a Lysholm screw type compressor made by IHI, Japan. Same type of SC but of less capacity was used by Mazda for their Miller cycle engine. In Germany this engine was installed in the Xedos 9.
I can imagine that Toyota will use similar if not same IHI compressor. Better choice than getting an Roots blower. (Weight, efficiency and dimensions.)
Somebody over there has or had such Mazda car?

well I looked at the toyota website, which is http://www.trdusa.com/default.asp and they will sell a supercharger installed onto the car for "well under $3,000" on the Pintiac Vibe and the Matrix. The same can be said for the Celica GT. I am assuming that there are some differneces between the Elise and the Celica though, including the ECU. If Anyone knows, doesn't the Celica use its belt to drive a power steering pump? If so, we would need a different pully. Also, installation might be a lot more money if the entire engine has to come out. That would be very bad news. The good news is that I think these problems could be worked out relatively simply. Of course, it would hurt the gas mileage of our little cars, but... I think I would be okay with 32 miles to the galon on the highway intead of 40

Now if only Lotus could give us some information about these developments

I have heard rumors of testing on the elise, but no concrete information. Hmmm

The TRD supercharger is for the 1ZZ engine, not the 2ZZ.
