I like that it can be installed on the car without engine removal and is not complicated for its power level so you don't have to mess with it too much like other options.
It reminds of a better version of the 2ZZ Greddy Supercharger kit that was discontinued long ago.
Power to the people ( with the dosh )!!!
A good quality turbo kit is not cheap either but the jury is still out on the ´great´. Cannot see it fit as they show it.
Looking at different shot from the Greddy, I cán imagine it.
Ditto the Lotus version of the Eaton M45

We´ll see when they will actually send it out and someone fits it.
Would convert the 2ZZ so fingers crossed.

I am tempted but mmmm....time and money!
To me it seems that it doesnt have a cooling core integrated. Lotus boe kits do and I think it could fit into in our cars.
£6000 delivered inc UK VAT with Black ECU and 525c injectors, or £4000 SC on its own.
Crazy money, as you'd still need a tune once fitted.
Also no cooling, the efficiency of the charger will be shite after a few hard laps and hp will be well down.
You could K20 convert to 240hp for similar money.

Agreed.
Now you all know how much I love a 2, but for a good standard 2 and this kit, we're now starting to talk Porsche or Lotus money. Also, bear in mind, by this time you've also spent a few thousand on a 2zz conversion.
Car: 4500?
2zz: 4000 (for a good clean conversion, at least)
SC kit: 6000
Further tuning and cooling: 600?
So we're talking 15k. Excluding further mods to the car for bracing and braking
No thanks.
Adding lightness by deleting things is cheaper yes :))
When a bit warmer thus the plastic less brittle will have a go at it again. Should be the equivalent of some 3 hp again ;)
I agree it's not worth the cost. I would rather sell my 2ZZ, recover costs and do a 2AR swap. The Greddy SC kit was much cheaper than this one which made it appealing for its time even if the output was less.
The 2ZZ is a good engine for the money with factory like reliability as a nice level up from the 1ZZ but that is where it ends when it comes to value especially these days when good ones are harder to come by.
My car has in the ballpark of 200BHP/tonne.
That's all I've really ever wanted, and that's why I haven't changed it.
I understand why some would want more, but for spirited driving, nobody needs more than that.

Yeah, my 2ZZ is slightly under that. I'm more than happy with my lot at this point.
I think as Scotte said, you can have too much power in an MR2 and it kinds of loses its point.
When I had my 2ZZ done, there was a supercharger available from a Corolla. The whole setup would have cost me an extra £2k which just wasn't worth the effort for a few HP more.

Tadashi Nakagawa was adamant that more power was/would be counterproductive to the nimble lightweight concept.
Imo a lower weight is a more important function in spririted driving than hp/ton. Take a 500 kg car with 100 hp vs 2000 with 400. The latter will be fáster but... still is a lardy through the twisties.
That said I would not object to say a 10 -15& fatter torque curve of the 1ZZ. Would prefer 50 kilo less though in case of a hypothetical choice.

Doing some quick math. I'm sure my built turbo build comes in at leas than £6k. If you've already got the engine.
Pistons - £520
Rods - £450
Turbo - £500 (Holset) but let's say £1200 for a garret.
Injectors - £200
Fuel system - £400
Exhaust - £500
Charge Cooler and pipe work - £500
ECU and mapping - £1500
Say the rest for miscellaneous.
But also assumes you'd build the engine yourself.
Two very different builds.

I probably did.

Same here, its a great power to weight ratio to have a great time with, more so on the smaller twisty tracks, Blyton, Mallory
