So the Eaton sounds like an easier install and more durable, but more limited for long term power gains? But a 300hp FWD Corolla would be undriveable on the street...

Pecker, here is a larger image for ya:

Welcome.

Yes, they are quicker than the heavier Celica. :)

Found some more info:

The supercharged engine in the Lotus Sport Exige 240R has a maximum power output of 243 hp (181 kW, 246.8 PS) at 8000 rpm and a torque figure of 174 lbft (236 Nm, 24 kgm) at 7000 rpm. This vast amount of extra power and torque now available means that the cam change between the low-speed cam and the high-speed cam now takes place at around 4000 rpm giving a smooth and linear surge of power from 4000 rpm all the way to the maximum 8500 rpm. The equivalent power output of a standard 3.0 litre engine was the target when the initial research and feasibility study got underway in the Autumn of 2004. Working closely with Lotus Engineering’s world leading Powertrain Research Team, the advanced 1.8 litre VVTL-i 2ZZ-GE engine was fitted with a supercharger and intercooler system.

Engine Down-Sizing is the Key

Lotus is one of the first organisations to not only recognise the changing market and legislative demands but also to actually develop a solution to the problem – supercharging a high compression ratio and high speed engine. Lotus Sport and Lotus Engineering had to ensure that there were minimal changes to the base 2ZZ-GE engine, which arrives fully dressed from Toyota for the Exige and the Elise 111R. The lightweight 2ZZ-GE engine, with a compact metal matrix composite alloy cylinder block, is a perfect unit on which to conduct the necessary research, as it runs to a high 8500 rpm, with a very high compression ratio of 11.5:1. The only changes needed to be made to the engine were the addition of a low pressure Eaton M62 Supercharger (and the longer drive belt that this requires), the intercooler and a new intake manifold, plenum and induction system.

The Roots-type Eaton M62 supercharger (with a sealed-for-life internal mechanism meaning that it does not require the use of the engine’s oil) is run from the crankshaft, and has an integral bypass valve for part load operation. Charge air (air under pressure from the supercharger) is cooled through a Lotus Sport Air to Air intercooler (the cooling air enters via the roof scoop) before being fed into the engine itself.

All charge air ducting has been kept as short as possible with large diameter pipes making sure that the bends in these ducts are not too tight, to the benefit of throttle response and efficiency.

Extra Functions for the Lotus T4 Engine Management System.

The Lotus T4 Engine Management system was developed for the Elise 111R and the Exige and is used again in the Lotus Sport Exige 240R. This engine management system has been reprogrammed to optimise the supercharged engine with two additional functions of controlling a fifth injector (located downstream of the intercooler to add additional fuel flow under hard acceleration or high speed driving) and to control the bypass valve.

If the Eaton is what Lotus are fitting to the new Exige's, then why not get the same "T4" engine management system they use?

I'm REALLY looking forward to how your conversion works out - this is my ultimate dream for my car too.

Oh, and I'd seriously consider an upgrade to the clutch, flywheel and definitely an LSD too.

Here's a pic:

(sorry to make this story a bit high brow, but I needed a word that conveyed "a lot". Now someone take it back to the gutter...)

was miraculously restored.

Head north on South Road and look to the left at Edwardstown... Can't miss it...

I would be interested if I had more notice but I'd have to start driving now to make it for this, but it you be a great surprise for my folks plus it my younger brother's birthday (21st) on Thursday 28th

If I knew you were that desperate for a cruise, I'd have given you more warning. Would you really drive back to cruise (oh, and see your family I guess)? :D

Finito.

The end.

off completely. But...

So there's a Lotus supercharger we can buy??

Well done.

Or something.

They're different fonts....

Look good but.

Valiant

Sick uleh.

The word association and 3 word story help a lot.

Seriously though, this community of Toyota fans really does rock. I love youse all.

Eibach springs, 35mm

The 3zz-ge is what they are calling the stroked 2zz's (using the 1zz crank and rods, taking capacity out to 1931cc).

falsies

I'll just pop down to the local Lotus dealer and order us both one then?

And yep - the ratios are very different, the car being half the weight and all...

Where: Meeting at Castle Plaza Shopping Ctr, South Rd

When: 9pm, Friday April 22

What: My Sportivo, my friend's 4A-GZE equipped AE101, and a whole bunch of crazy dudes from the Toyota Car Club

Doesn't Trial have a supercharger for 2zz??

>goes away and looks<

Yep, here it is:

Trial Japan link

For this and the stroker kit they want like US$8000 each

Hi Guys,

Just for those that are interested i found out toyota will be producing 1000 supercharged T-sports

250 will be coming to the UK a bunch going to Germany and other all over Europe. As it is a t-sport it doesnt appear there are plans for a supercharged sportivo......

Yeah but, couldn't we get our hands on the genuine parts i.e. supercharger + ECU??

love from my...
