You have to call a special number and speak to a person that knows what they are talking about. Also the only Elise that was not driveby wire was 2005. It also not possible to use a Celica GTS engine because of the intake. It's not just the engine you have to use the whole intake and EVAP canister from the donor.here a question, I did call the bar before i bought my 2zz spyder, he said it will not be legal to put a front wheel drive engine in a mid engine car. but I think it a round about way it was more about not messing with the exhaust manifold and the mid pipe that will not necessarily fit. so why not use lotus elise stuff? it should be easier and repinning the ecu?
The best donors are 2003 Matrix XRS and the Corolla S because the stock intake in easier to work in the spyder. Also it's best to find a pre 2004 donor because 2004+ has air injection.
You can't modify the exhaust manifold. You have to modify the subframe and use the unmodified exhaust manifold from the donor.
If you have a 2004 or 2005 it's much harder since you have to use a 2004+ donor.
