Corolla XRS Supercharger???!!!

Ichi.. stop reading the posts by looking thru the beer bottles.

s/c NEVER gonna happen for the 2zz.

[dark_serphen]

rumour is rumour....but will u sure that it would have enough room to fit under the xrs hood?

or maybe xrs sc kit has discription 230 hp... but was that the motor or @ wheel? or just the number?

i believed that the 2zz has lift already...so the sc shouldn't be working..

Yeah that was my original thought too....ie: too good to be true for 2zz.

But it's nice to dream after you see that in print.

The lift happens because of a lot of different variables - if I remember correctly it is based on the air temperature/load and when you add any type of forced induction it cools the temperature of the air down and hence the lift doesn’t happen - this can be re-programmed - but you must also remember that you have a 8200rpm redline and many other engine improvements over the basic 1.8(1zz I think)

Actuating lift has nothing to do with "air temperature/load", whatever that's supposed to mean. Lift is actuated by high RPMs.

Forced induction does not cool the air down it heats it, that's why you need intercoolers. After it passes through the intercooler whether or not the air entering the intake manifold is hotter or colder than the ambient temperature would depend on how much boost you are running with what application and how effecient it is.
If we are talking about a non-intercooled supercharger I would think the air would actually be hotter.

When you talk about different variables affecting when lift engages, I think you are thinking about the cam phasing, or VVT-i, rather than the cam lift (the "L" part of VVT-Li).

Read this link to get some idea of how VVT-Li works:

Oh sorry i must have got my info mixed up...thanks for the info.
