...some of the celica GTS folks have pulled 600 horsepower from their 2ZZ-GEs as well, built internals of course - i haven't seen one in person, but i imagine they must sound not unlike a screaming formula one motor...

The 2ZZ-GE motor is heavier than any 1.8T motor ever could be.The cylinder head on those engines are massive in comparison.

You might want to do some research before making such claims. Lotus chose the 2ZZ-GE because of its light weight. Lotus Elise Toyota Engine Comments Here's a link to the SAE white paper on the development of the engine: http://www.mmsport.com.au/download.php?fid=34

Also, as to the whole premise behind this thread, I found this: Lotus Blossoming - Auto-Teknix Elise 1.8T Conversion

BTW, according to that, the 1.8T weighs 88lbs more than the Rover K-Series engine.

Not sure whether you're a troll and we just didn't take the bait; but thanks for playing. If not, I apologize.

This seems appropriate:

...the cylinder head may encompass a larger volume, but a lot of that is empty space - the material mass, especially down in the block where it's very thick, is much more significant...

That is with the manifolds and turbocharger on it...not the physical engine itself.

No apology needed...it is hard for a new comer to enter your "realm" and try to bring something new to the table.We do it all the time to new members on other forums so I almost expected the same treatment but never this rough.

Getting back to the original topic,so I take it no one in here has done the 1.8T conversion.

If you are in here please show some hands and thanks for having me here!

I dont think you are being clear on what you want to do. But if what you want is to drop a 1.8t on a lottus chassis ask toyota dont ask audi/VW. The engine block on Lotus is Toyota Celica,MR2,Camry. 1.6L,1.8L,2.0L,2.2L.

I've just started fitting an Audi 1.8T in my elise S1, you can follow my progress in the thread above. There are about 5 companies offering the conversion, but mines totally DIY, I've never done one before.

My choice was between The Audi and Honda lumps, but having had a tuned VXR220 track car previously, I have a great love of small turbo engines and the Audi/VW unit is cheap, abundant and easy to tune in the UK/Ireland.

To be honest, so far its not proving a hard conversion, several guys have told me it took them a week of actual man man hours after the parts are sourced. Its quite small and the audi engine mounts can be used by putting spacers on the Lotus plinths. The Toyota gear linkage when fitted to the Audi, I've been told, gives the best gear change possible in an Elise. Driveshafts can be a combination of the Rover/Audi or a bespoke shaft is available. A fan assisted intercooler is usually added beside the left air intake and the single downpipe is only a few bends away from mating to a muffler in the standard position.

If there had been a Toyota lump in there already, i wouldn't have touched it, but its an excellent upgrade to the Rover engines.

Has anyone heard of an Elise running a duratec? There are versions running 300+ hp. Just a question.

Yes - again in the UK it has been done but doesn't seem as popular as the Honda/Audi swaps.

Vitriol aside, it just seems to me an engine swap is a great deal of work with details that will be very time-consuming.

Once the engine is actually bolted to the car and fits, that seems the easy part, as much work as it is. You have to get drive axles that will match the length, angle and splines needed to drive the rear wheels. Then you have to plumb everything, intake, initercooler, exhaust, oil, water, and fuel. Then the electronics, and getting the audi or aftermarket ECU to talk to the dash. I also assume you want all you warning indicators to work, such as alternator, so that needs to be made functional. Some of these tasks might be easier than I'd expect, but I am sure many of these tasks will have details that will be very time-consuming.


At the end of the day, does the perfromance potential of a complete transplant exceed the expense of developing what is already there?

I personally doubt it, at least that the extra is worth the effort. I have gone the 2ZZ with turbo route, as at least the engien fits the car and I don;t have to fuss with mostof the above details. I do have to deal with engine internals, sleeving, and gettign an engine not developed by the factory for boost to live with forced induction, so that is the tradeoff risk.

You are correct, the 2ZZ would be the best tuning option.. if you have one. The engine swap popularity in the UK is a result of the the vast majority of Elises having the 118bhp Rover engine.
