3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
I am going to build a gen 3 XLE. I am hoping for coments on choosing between the 3vfez and the 3mzfe. I like the strength and durability of the cast iron block but think the weight savungs of the aluminum block might be a bigger advantage. I am looking for 250-300 hp. What kind of mods would be required? Any input would be great.
if your thinkin NA then 3vz is the way to go. its a pretty good NA motor...well compared to any of the other options.
if you thinkin of FI then the 3vz is still good because its a little beefier and is OBDI so its easier to screw with. but the MZ's have more aftermarket parts avalible.....and by more i mean it has some.
I am think I'm going N/A. That said I am willing to spend up to 10-12K including paint because I want a brand new car that will last longer and run better than anything that is on the market in the last 2-years. Is it possible to do a stock turbo on the 3vzfe? Or do i need to go to the 3mzfe, or is it the 1mzfe. As I said I am going to build a car that is as close to new as possible and am willing to spend what it takes. Thanks for the input.
Well, 3VZ and 1MZs are both 3L V6s... the 3MZ is the 3.3L from what I know.
If you're wanting to N/A it only, go the 3VZ. If you DO go down that track, at least replace and build the engine up again (Head gaskets for sure). A decent port and polish and a nice exhaust with all the restrictions taken out can net you some nice power. Look for Toysrme's info on the 3VZ. He knows his shit mate.
for all out power the 3mzfe(or hybrid) isnt a bad idea. the stock 220 or whatever is pretty good and stock would have more then a lightly tuned 3vz. but its expensive to have and it takes some work. the 3vz is easily tunable up to 200hp from the 186 stock. but the 1 and 3mz is much harder to get NA power out of because of the OBDII. building up a 1m or 3m will requier a good EMS. a typical piggy back isnt really god enough if your doing a big NA build.
if your lookin for quick and easy power and have them money. then id suggest 1mz and find a TRD SC. it will easily give ya thoes numbers with few upgrades, is very easy to work with and install(the SC i mean) and is very reliable when kept under about 10 psi. any other path will require some creativity(TRD SC was only made for the 1mz).
OH and plan on getting a manual too. that 300hp wont be worth dick without it...trust me i know.
What about the wiring harness for the 1mzfe SC. Is there a stock harness or am I going to have make my own? EMS? Do you mean engine control unit (ECU)?
well if you run anwhere under about 7 psi then you can get away with a piggy back like SAFCII or somthing like that. over that then a stand alone EMS(Engine Management System) is the best bet because it will get rid of your pesky OBDII stock ECU.
hell on 4 psi ya really dont even NEED a tuner(wont get ya close to 300hp though). ive been driving around for a while on the stock ECU and simple fuel upgrades. but a tuner is definatly recommended...and i will be getting one.
So the 1mz bolts into the car on the stock mounts? Im still confused about the harness, do I use a 1mz harness and patch it in, or will it go in as a unit with no mods? The 1mz sounds very intriguing, but I am more of a mechanic than an electrical engineer. If the 1mz requires rewiring than I am going to stick with the 3vz low boost and an EMS
if you already have a 3vz then drop the swap idea. if not then either motor will require rewiring and new mounts(i believe the mounts are the same between the 3vz and the 1mz). youd use the ECU and harness from whatever your putting in so youd have to do wiring in either case.
just make sure you swap in a manual, or whatever you do will be a bit of a waste.
3MZ block with Non-VVTi 1MZ P&P Heads, E153 5 SPD Tranny, Bigger Injectors, Piggy Back, 1MM Over-sized Valves.
That is my favorite N/A build - Hybrid Motor.
FI - Throw forged rods/pistons in there and throw a GT28RS on there or a CT26 or something, you make 400....
Question is asked way too much...how much you lookin to spend?
RBAY: 3VZ with Intake/ custom y-pipe/ advance timing/afm mod/Exhaust/E53 5spd tranny would make serious power and torque on OBD-I. throw a turbo bigger injectors and a retune on the afm and it'll make 3-400 hp with a fat torque band better then any MZ-fe engine.
if your goin for 300+whp then either motor will work and have to be built. even the 3vz looses its advantages when your lookin to upgrade that much. the motor has to be built up, ECU replaced with an EMS so the OBDI advantage means little, the torque curve changes with boost and the internals need to be upgraded(cept for the rods in the 3vz i hear are pretty solid). the 3vz is heavier too.
sub 300whp and id say 3vz over an MZ(unless ya want a lighter engine). the only reason id say 1mz at all is the avalibility of aftermarket parts and the SC...other then that id 3vz it.
