3mz head on a 1mz block?

[Xevuhtess77]

not sure if this has been covered before.... a serach didnt turn up anything

would it be possible to put a 3mz head onto a 1mz to make my 1mz capable of VVT-i?

[Fresco Bob]

ya its been covered. no it wont work, because the 3mz only has 1 throttle body, where as the 1mz has. Or maybe the other way around. It definitly had somthin to do with the throttle body tho.

it could work if you are smart and can figure out hoe to make it work... but there is absolutly no reason to want to do it... just swap in a whole 3mz motor... then you will have the extra .3 L too...

depends on what year 1MZ u are talking about, the 03 had one throttle body, same with the 3MZ

[Xevuhtess77]

hmm, my thought was to just use a whole 3mz top end on my 1mz..... my 1mz's a 94 though. mabye its too crazy of a project

i really dont see a purpose in it... i mean, yeah it would be different, but spending so much time and money for difference? no... dumb...
if you want vvti, you would grab a whole 1mz or a whole 3mz and just use that whole motor, whole wiring harness, and you have a LOT of wiring to figure out...

i dont think you can just change the head anyways. you need to program the ECU and junk . My friend did his V-tec head swap and he has no v-tec dude to the lack of ECU or a V-tec controller.

So yea i think even if you can fit a VVT-i head on there, there is more to make the VVT work.

Don't late 1MZ's have VVTi? Wouldn't that be a more feasible swap?

03 and up 1MZs have VVTi but its probably not gonna be cheap for one of those with everything your gonna need

the head gaskets are the same for a 1mz or 3mz

the plenums on some 1mz's were doubled to increase airflow. but the lower intake manifolds are still the same.

putting the 2 together might give more benifits then just doing a swap

1mz heads on a 3mz block or vise versa.

on our SGP race motor setup we are using 3mz block and 1mz heads, to eliminate the vvti, but still get the displacement. ben is building 3 motors the same; 1 for his ae86, one for my coupe, and a spare incase one has a problem.
