3VZFE for MR2... How much HP you guys making???

[hmong337]

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:

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.

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

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!!
