lotus engine Options

[celiman5]

hey i was just curious but would a lotus engine be able to fit and run in our celicas since the engine is toyota based. i know it would be super expensive, but i was just wondering when i was reading a magazine with a lotus in there that, would it be possible.

the 2zz in the Elise and Exige is the same, with just a more aggressive secondary cam shaft so the VVT-I kicks in a few hundred rpm sooner nothing crazy. But the 2zz has no low end TQ thats why u often see superchargers and not turbo charges on the 2zz, the Lotus Exige has a Supercharger on it, and is very detuned and makes about 230 hp and almost 170 foot pounds of tq. but all in all a very fun power plant 2 have in any light car.

There is no such thing as secondary camshafts in a 2ZZGE.
It has secondary cam LOBES.
Which have nothing to do with the VVTi.
The larger lobes are the L [Lift].
VVTi is adjustable valve timing and only valve timing.
The camshaft itself has nothing to do with when the timing is changed, or by how much.
The ECU determines this.

And the L has nothing to do with when it comes on either.
That is soley decided by the ECU. It has a set point programmed into it.

i meant "lobes" each of the 2 cams have secondary profiles, which in the vvt-"i" are continuously variable. all lotus does is make some changes 2 the ECU and even out the hp and tq cuves.

But they're not....
The secondary lobes are one set profile.
The VVTi has NOTHING to do with the lobes. The lobes are the L [lift] and ONLY the L.
VVTi is on the end of the camshafts, where the cam gears are.
THAT is what is continuously variable.
And it varies the valve timing, not the lift. Or the secondary cam lobe.
