So far i know it must fit a work on a gen3 1m-zfe.
But maybe you must block the egr and rewire some vacume lines. And if it came with a ECB there is a change it will not fit. All those things will not be a problem but cost a lot of time. (search on gen3 and s/c on this form)
Before you go install buy a Apexi Afc, A/F meter (wideband is the best), and install GM knock sensors. (500-1000 dollars)
I have got some (big) problems because didn't. (With stock 4psi)
Read and ask on this and
www.solaraguy.com form before you begin install! (knock sensor problems, A/F, Apexi AFC, max 5- 5.5psi, fuel injector upgrades, 2.5 inch exhaust and more fun stuff)
I don't want to make you affraid but it is not always so easy they say......
I think it is cheaper to sell your car and buy a faster car.......but it is not a Camry with S/C sound
