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.

I've researched a bit and I leaning toward the 3vz.

I've researched a bit and I leaning toward the 3vz.

im going back and forth, havnt decided yet. hard to pass up the 3vzfe because you can find them so cheap. here are some pros and cons of each.

3vz pros: heavily built, wide powerband down low, cheap, easier to wire with obd1, great engine for FI, receptive to tuning cons: heavy, older engine, less power up top, illegal

1mz pros: lighter with aluminum block, great for NA, newer engine (presumably more fuel efficient), available with vvti, available trd supercharger, legal swap cons: more expensive, weaker internals, knock sensor problems, sludge problems pre-03, harder to tune
