the v6 swap information thread, UPDATED 3/1/07 Options

[celicaST]

why am i making this thread? after seeing K-ESD's completed v6 swap, i started looking into it as an option. the v6 swap has been a popular swap in mk1 and mk2 mr2's for a while now. v6 swap information is relatively sparse for the celica community, and i want to help change that. seems to me that too many people here jump on the 3sgte bandwagon without really exploring their options. there is a reason that owners of mk2 mr2 turbos are swapping out there 3sgte in favor of a v6. a v6 (by nature of its increased displacement) will give more low rpm torque than a 3sgte will stock for stock, and such, it makes a great daily driver. with relatively moderate modifications, a v6 can be made to produce huge hp with a wide powerband. and the best part, these engine are a dime a dozen. use www.car-part.com to find them locally in salvage yards for cheap. now there are a lot of options for a swap: 3vzfe, 5vzfe, 1mzfe, 3mzfe being the most popular. i myself plan on doing this swap either summer 07 or summer 08. i will be updating this thread with lots of info ive gathered, and it will be regularly checked checked for accuracy and clarity.

purpose of this post is to generate interest in the v6 swap and to provide a one-stop place to compile general and 6gc-specific v6 swap information.

My input would be

You need:
Motor: 3vzfe, 4vzfe, 5vzfe, 1mzfe, 3mzfe
Transmission: V6 Camry, V6 Solora, Turbo Mr2, ES300 (E153 or auto)
Motor mounts: altrac mounts on all side except for front GT motor mount ill work, passenger side will need to have an adapter plate
ECU: best to use a Camry, Solara, or ES300 ECU or use a EMS
Engine harness
Misc: Custom Y pipe as said already on the thread, metal HG for 3vz users,
Axle: ??? <-- havent got there yet.

I know i'm missing more stuff but I will keep updated with my project.

i have an AT200, would the alltrac mounts work w/ the 3VZ still?
