the v6 swaps are becoming more of a better idea (and will probably be the next trend) putting them into our mr2s. as this engine is derived from you camry guys, my questions are:

how much hp are you guys making with mild to wild setups? is there anybody pushing 300whp+ strictly on motor without sacrificing daily drivebility?

I hear that it's pretty easy to push a 3vzfe with relatively inexpensive mods for over 300hp. True?

To have a 300rwhp all motor v6 mr2 would kick royal ASS!

help me out guys. educate me on your 3vzfe motors

all the best,

it can but its hard. all parts have to be custom made since there isnt anything avalible. the 3vz is a slightly stronger engine then the 1mz and can handle boost better as well. i know ive herd of people supercharging the both the 3vz and 1mz in the MR2, i personally havnt seen this on a 3vz but the 1mz i have and it produces some nice numbers. teh 3vz is supposed to be a good motor to turbo but i can only think of one person with one(toysrme, if ya can find him). there are a couple people with turbo 1mzs though and plenty of us with S/C 1mz. but i have yet to find someone with a 300hp NA 3vz or 1mz, it would prolly be cheaper to jsut get a 1mz, the supporting mods and then S/C it.

have ya asked this in the MR2 forums?

 

[hmong337]

thanks for the prompt reply. the funny thing is that Toysrme posted this on the V6 section of the mr2 forum that i frequent:

board ate my post last night. :\ sigh lol

neways. McE ran his turbo over a year before parking it at well over 400bhp no ems (i put him around 475 personally based on that turbo & what he was pushing) before that over 400bhp worth of the juice for two years, no ems.
there's a half dozen 3vz camry's on toyotanation that run the bottle no ems (anywhere between 75 and a 200 wet shots, one 125 dry shot no ems) three on there in the last year running 125 - ya about 350 at the end of the day, but close enough...

the obd-I of teh 3vz-fe would easily let someone get away with sub $300 worth of fuel mods to make 450bhp'ish. no aftermarket management required. it wouldn't run as well a car with another grand dropped into EMS solutions. the point is that it could be made to run perfectly acceptably & safely until around there.
HP fuel pump $100
12:1 fmu $100
fuel filter $15
new plugs $12
the differance is that the obd-II cars will run rich enough to foul the plugs & go lean under boost over time, where the older engine will simply run rich under boost until your fuel pump chokes. on a 12:1 FMU you won't see a wideband gauge do anything but bottom out at a 10:1 A/F ratio until around 350bhp even in the high par tof the middle rpm ranges.
we have yet to discuss starting off with a mild injector swap that the ECU will tune itself out during closed loop once warm yet!
tehehehehehe nor have we said you *probably* wouldn't need to touch the distributor for a measily old 350bhp since they're so retarded from the factory. we all just do it for peace of mind really...
or water/alcohol injection lol

nor have we discussed replacing the stock fpr completely with a $200 fmu that has adjustable base pressure, and adjustable rise VS manifold pressure. now you're opening the door to running relatively large injectors acceptably in closed loop without EMS.
<- still not discussed mild afm tuning to help those injectors life on the street either.

3vz-fe motto = get there cheaper, with more faster; if you're not opposed to applying FI.

 

[bigbird]

i suppose i should have mentioned he is around, just not around here anymore.

 

[hmong337]

also, how achievable is 250hp naturally aspirated on the 3vzfe? generally speaking, how much hp would i see from modifications such as:

port and polishing heads, intake, exhaust, and basic fuel tuning?

is force induction the only way to go to make 300hp+ easily? i ask because it's pretty crammed sticking a turbo on a v6 inside the mr2's little engine bay.

thanks

 

[Luckynumber5]

LoL the turbo placement is no problem, after seeing Node's twin turbo 5vz-fe setup in person I can say that a turbo kit will not be hard to put together.

The 3vz is a lousy setup to try and build for all motor setups, the 1mz is a much better choice in that instance. With an excellent port job using epoxy to make the ports smaller for higher velocity it should make some ok power, but it has to have some form of forced induction to really shine.

 

[bigbird]

FI is tough but other have done it and thats gonna be the most ecinommical way to 300...or even 250. a S/C (stock) 1mz (stock) makes nearly 240 crank and with suppoorting mods 250 whp is easly obtainable.

you serious?! if that's true, than that's pretty crappy power (no offense). a 3sgte would be better off. although the torque band wouldn't be as sweet as the V6.

So what have the 1mz guys made going only motor. Obviously forced induction will always bring in nice numbers. But the reason why I like the NA setup is simply of ease... no plumbing, no extra lines, more space for easier access, less rotating parts, etc...

 

[bigbird]

no offense taken...its not very impressive but the stock setting is only at 4 psi. but you can get some good power from it. though the most ive seen is about 350whp. this setup was never ment to make big power and quite a few MR2 guys who have done this did it without knowing that, have been VERY dissapointed. i honestly say 3sgte or turbo 3vz.

the big selling point is the ease and reliability of the setup. it was made to be able to bump the hp on a stock engine and trans. not produce big hp numbers.

there are no N/A 1mz or 3vz's that make over id say 230hp(crank)...maby, that i know of. the cost involved is just to much for what ya get, combined with the fact that its in a camry which is heavy and not a good platform for modding, there just are not many who have done an N/A build.

 

[hmong337]

shocking! and here i thought the v6 would be the holy grail to our lack of power in the mr2. i was thinking they'd atleast make 250whp with some relative mods without the use of force induction since they're a v6. guess i was wrong. and the cost of swaping in a v6 plus doing a custom turbo kit, what a nightmare! with the 3sgte, 300hp is pretty darn easy to achieve. i think i'm gonna conclude that the 4 banger turbo is the only way to go... UNFORTUNATELY!

 

[bigbird]

why, you wont have to swap a huge v6 and weigh down the car. i would never consider a v6 after what i know now about these motors. 3sgte ftw.

 

[hmong337]

powerband is what made me think about the v6. a flat broad torque band in the mr2 would be a serious track racing car. it's a darn shame you can't extract much power out of these powerplants. i guess i'll have to settle for the gen3 3sgte in my future swap...

however, if you guys can still provide dyno charts of what your v6's have done that's be great.

all the best,

if you want a track monster, I'd go with a 1mz + supercharger for the wide power band and crazy torque, but then, I'd say make sure you have an lsd as well- especially with the mr2's shorter gears

with enough supporting mods and plenty of boost + alcohol injection. 300 whp isn't impossible to reach while also keeping driveability

 

[bigbird]

im courious, whats capable on the 3sgte? ive honestly never seen one above 350whp or so.

and what kinda track we talkin here? road course or drag? if road id still stick with the 3s to save weight. but that bassed off my common sense and limited knoledge of both MR2s and swaps on it.

Word!!! There are a lot of 1mz/3mz parts for sale on the sale section too!! Including a SC.... Just click on my sig!!

I think maybe a little over 220 crank hp can be coaxed from the 3VZ, anymore will cost a lot of money.

From my research.... A custom well made Y-pipe with full exhaust and high flow cat can give up to +15hp.... Toysrme told us that.
Other little researches tell me that port and polish the head and headers with bigger valves and valve springs will give some hp. 5-10hp I think?
Cams do nothing.
Adjusting the AFM and timing will give up to ~10hp, I think Toys told us that too.
Or get a SAFC and a tune. That gives some, dunno how much though.

So I would guess on a manual, that would be ~200whp with REALLY nice torque band.

There is also the JDM 3VZ which no one has which makes 205hp and 209torques stock. The USDM 3VZ is 185hp and 190tqs. Heard that only comes in auto though.

the 3sgte can do 300hp easily depending on the generation...

the 90-93 engines (gen2) can see 250whp with just minor mods like a boost controller, fuel cut, intake, exhaust, and an intercooler. the fuel system limits the gen2 to around 275whp.

the 94+ engines (gen3) have recently been seen to make 300hp+ with just minor mods. the fuel system on the gen3 is limited to around 320whp.

350hp on the 3sgte is easily achievable by just doing a fuel system upgrade, a larger turbo (gt3076r, t3t4 50trim), and something to control all of that like a power FC. stock internals are safe for 350whp or less. Although some have taken a 200K mile stock engine up to nearly 500whp before it let go. So the 3sgte is no doubt a potent power making engine. but with all 4 cylinders, they lack the instant torque and powerband of the V6 no matter how much power they make.

to do a 3vzfe or a 1mzfe with a supercharger is ridiculously not cost effective at all! c'mon, the cost of the custom swap coupled along with price of the supercharger... then having to upgrade the supercharger and also doing fuel management. that's insane! i'd never sink that kind of money into an mr2 as i'd be better off with a supra or something by then...

looks like the 3sgte is the only way. however, some have been toying with the idea of the new 1gr-fe or the 2gr-fe but those engines are too new to know anything about them. not to mention the obdII systems on those engines are so crazy due to emission complaince etc.

 

[Luckynumber5]

Uhh, I think most people on the mr2 v6 forums have managed to swap for under $1000, going turbo is simple after the engine is ready to go in.

Please don't come overe here and ask questions most people don't know the answers to and then talk to them about the 3s-gte :lol: a turbocharger is a pipe dream for most on the Camry boards.

 

[felonyr301]

Take your discussion to the mr2 v6 forums and you will see they will tell you that the 3vz-fe turbocharged was the best thing they did compared to having the 3s-gte. Superchargers is not the most cost effective on the V6 when trying to make alot of power. If you already have an mr2 just swapping in 3vz-fe and turbocharging it still comes out to less than $10,000 considering the end cost totals of who did the swaps. With the right turbo on the 3vz-fe you will make alot of power and still have that lovely torque down low that 3vz-fe is good at. IMO superchargers is not my cup of tea, plus the TRD one is not even good compared to the other chargers they made for other cars like the scion tc and such.

 

[bigbird]

its true that the TRD/kazuma(think that the manufacturer) for the 1mz isnt the best. but again...it was NEVER ment to be. its made strictly for a very reliable slight bump in hp. for god sakes, some guy(Jim) with his inginuity had to create a part that balanced the fuel to the front and rear banks and keep the engine from running lean. somthing TRD never even addresed:lol:.

from waht ur sayin, i say 3sgte all the way. save the weight and it has to be easier to do then a 3vz turbo. leave the TRD S/C for cars that have no buisness being really fast cars:lol:
