My 1MZ progress thread by Smaay

well i fixed the axle issue. i had to grind off about 1/16 " off the tip of the drivers side axle to get it to seat all the way into the trans. im not certain but i think i have an aftermarket LSD in there or maybe a factory. but its not the same as the MR2 because i dont have the bar through the middle. i can see some sore of place with a hole through it inside. and both wheels turn in the same direction off the ground. i am using MR2 turbo LSD axle stubs. im also using ST185 outters and no spacer, so far no issues.

^^^^ thats so sexy! thats what im going to do once i get the swap certified. I have a complete 3MZ from a Sienna. i just need to get the VVT 1MZ intake manifold, throttle body, and the computer. how much power are you making by the way? 

after driving my 3MZ/1MZ hybrid i can tell you that this is so much faster than my dads 2002 5 speed solara. it is also much torquier and faster than my 5S-FE with the turbo system on it. Once i get all the bugs worked out ill be fabricating the supercharger. 

Oh by the way my cruise control is also working. im so happy about that.

got the ST throttle cable in on saturday. OMG full throttle lights the tires up in 2nd gear and im on 17" KDWs! this engine is awesome! i need to put a resonator in the pipe it sounds like a freaking honda straight pipe though. my O2 sensors should come in today. once i get those installed i should get STFT and LTFT data.

i havent noticed any issues with a CG or weight transfer. the 1MZ weighs just about the same as a 3S-GTE and the E153 was designed to be in there. remember its the same trans as the ST205 tranny without the transfer case.

you could always sell the 3S and make some of your money back. the way i see it, you could buy a complete 1MZ with ECU and harness for about 7-800. 400 for the wiring work, 200 at most for an intake, and maybe 300 at most for some fab work for the engine mount and an axle carrier if you use the S54 trans and axles. thats a total of 1700

oops i forgot to add exhaust work. probably another 500 to build a Y pipe and down pipe. depends on where you go.

^^^ yep, i just searched car-part.com until i found a good engine close to me. i actually went to a junkyard in Bakersfield (about 80 miles away) just for the axle carrier bracket and I ended up buyine the entire 3MZ engine from a Sienna. it had really low miles, the harness, and ECU for 700 bucks! cant beat that!

i used this thread for all the information http://www.mr2oc.com/showthread.php?t=359007 

yes the 1MZ heads "basically" bolt to the 3MZ but you have to block off 3 oil passages and restrict 2 of them. its not that difficult to do.
