1ZZ -> 2ZZ

[Anonymous]

Ladies and Gentlemen,

my MR2 is in sevice now. It's complete rebuild operation so both engine and gearbox would be removed (I think are removed already). Maybe it's a good chance to replace 1ZZ with 2ZZ?  :-) :-) :-)  Is there anybody around who had replaced engine but kept old Spyder 5 speed gearbox? What else except engine itlself should I also replace? It've looked for HOWTO or FAQ but it seems to be missing...

Thank you!

I'm the only person in the UK that has done the swap so far.  There are many people in the US that have done it, see  w www.spyderchat.com w

The 5 speed gearbox does fit and work but peolpe seem to think that the gear ratios are set all wrong to work well with a 2ZZ.

As well as the cost of the engine you would also need to save money for an ECU, header and intake.
