1MZ auto into Z20 soarer

[Dj Labby]

Hey guys and gals.

Well i'm a bit of a noob on this site and to toyota's in general, however i know and can do a few things to cars.

Well i bought a pretty much immaculate GZ20 soarer with 3"exhaust and a boost increase, but it realistically has no balls!! coming from my last car R31 skyline with turboed rb30's and even N/A's this just doesn't even compare to stock 31's (not bagging toyotas out).
Yes i can go the xJZ route, with some hassles or 7M, but they are a pretty shite engine i've heard. So after driving my missus Camry for a few years now, i think it has a pretty good base to do a conversion with. It has power and torque(more than the RB30 N/A), its light, and quite compact, leaving room for things like turbos later!!

Ok so i have searched, oh have I searched. Yep, there's a bit of info out there, specially for manuals.
Just not too sure on Auto's though. I have a feeling it could workout easier than expected, but realistically probably gonna be a C**t!!
Ok yes i'm aware of using a 3vz bellhousing, thats established, but which auto??
Can i use my 1g/7m auto, or for that fact even the bellhousing?? or would it need something like a xJZ/1uz auto? Would the flex plate from a 3vz be a match?

Also there are some recent/oldish threads out there that list the build 1mz>TA28 but just stops at 'Box is in the car'.
Any news on how the car actually goes, or wiring issues? Can't find much on that. Good build though.

Anyways, any help would be appreciated.

If this might be difficult, i may look into dropping a Dirty30 turbo into the soarer for shits and giggles, as they are easy as and i have heaps of good parts for them... Sorry..(can hear too many people shrieking) haha

Thanks
Rob

Unless you are doing it solely to be different, just drop a 1JZ or 2JZ in there.
The outcome will be 10x better, the effort will be 10x less, and the cost will be roughly the same.

To go with the 1MZ you'll be up for a custom sump, custom mounts, custom exhaust, custom starter motor mounting, and thats just the beginning.
AND, until you boost it, it WILL be boring as batshit to drive.

[Dj Labby]

Point taken. I have enquired about a JZA70 cut, bout 3k, which should get me most of what i need for it. Yah i know, the tried and true method is always easier...
Still be interesting...

Cheers

If you've got your heart set on it, go for it.
But, there is a reason why its never been done before... just remember that...

[Dj Labby]

Hahaha, yah fair enough. Gees i've been putting these thoughts in my head, now you crush them like a flea.
I'll still look into it. If i can come across a motor cheaply, then maybe. I'm just wondering if the 3VZ and 3vz-fe have the same block, ie the starter relief in both. Can get the camry 3vz-fe cheap enough. Might have to trek to pick and payless to have a look. I'd tossed up the 1uz option, but have had many people say it wasn't really benificial and went to 1jz anyways.
Oh well, we'll see. I have or will have a front of a mz20 (just wrecking it atm) so can always use that as a base to check things out prior to inserting to my GZ

Thanks

quite like the idea of a 1mz being alloy and short should make for awesome handling. intake will be a pain as it will face the firewall.

Well, if a 4.0L NA isn't good enough, then a 3.0L NA isn't going to do squat.
Which means you are going to HAVE to boost it.
And if you are willing to do that straight off the bat, then you may as well go the 1UZ, and boost that, and have 4.0L instead of 3.0L...

and have in some ways a much easier conversion!

btw, your standard 1ggte make more power and toque then a 1mz, not to mention its not hard to get a extra cheap power from a turbo engine with some basic mods. so your actually going backwards until you turbo it. just think it would get blown off by nanna in her standard camry!

[Dj Labby]

You reckon it has less power and torque than a 1g? Interesting. I'd say camry and soarer bout the same weight (within 50kgs) but i put my foot down in my missus 01 camry and it really gets up and boogies!! i put my foot down in my soarer and i have to wait literally 3-4 secs before anything happens. Really annoying trying to get to the other side of the lights if you have to quickly!!
Sure i 1uz would be better than a 1MZ, but you have the extra weight plus less room in the engine bay. But yah it would make it an easier conversion. Probably cheaper too. Hmmmm anyone got a 1uz?? haha Where to put turbos though.. not much room. Fortunately a V6 (besides the stupid ecotec) is 60deg V and a V8 is 90. so there is more room at the sides. An LS1 would fit nicely though due to the rocker covers being smaller and less rocker gear and cams.

Anyways.... Maybe i should just keep dreaming and put a little bit of effort into the 1g. I have a KKR380 turbo i can whack on it, just need to make a manifold and i have a big cooler that i'll try and squeeze in the front. That yield some results. Miss my RB though. :-(

[Shakotan_Aaron]

you have a turbo engine with a very lazy sluge-matic, so the small amount of turbo lag is accentuated by the auto. you would probably find a manual more zippy (and more fun). also bare in mind that the 1G is a revvy engine so it makes power higher. 5mins of searching i couldnt find the camry weight so cant confirm that, but i would have thought it maybe a bit lighter, also it would be naturally quicker due to a bit less drive-train loss.

these figured pulled from wikipedia.

1MZ-FE
168–190 hp

1G-GTE (GZ20)
211 hp

Me personally, im not a huge fan of V6 engines, if you where set on one then a VQ35DE would be worth a look at 280hp out of the box. but they arnt going to be a few hundred like you could probably pick up a 1MZ for.

The extra weight would be like 50kg, hardly worth worrying about in the overall scheme of things.
Yes, its a very tight fit in the engine bay, but plenty of people have turbo'd them in the last few years, so its very do able.
Failing that, pick up the phone to Bullet and order a HTV1900 supercharger for it.
Bolt on, 10psi no issues.

Anyways.... Maybe i should just keep dreaming and put a little bit of effort into the 1g.

If you are keeping the car, ditch the 1G, it will never inspire you...

If you miss the RB that much, then just 2JZ it.
It will drill the RB in almost every aspect

engine is too small for the weight yes,

jz>rb

oh an even a 1j would be fine.

[CELICASUPRA7M]

Well i'm going to go against the grain and say "put a 7mgte in it"

that is all.

[Shakotan_Aaron]

it would be the easiest way, shouldn't need engineering either as they came with them from factory.

DJ labby?

Dont have any for sale do you

If you think a camry is zippy you will kill yourself in anything with a 2jz.
