Hello every one ! My name is Troy i work for a salvage yard in Florida .
Enough with the small talk i'm here for one reason and one reason only and that is to put a v6 in my 1997 corolla dx.
Some might think im crazy and others will say no big deal . I have been doing research for close to 6 months now ever since a drunken you tube visit led me to a corolla with a 3vze swap.
Now i am 100 percent sure i can do the swap im mainly here to share my progress along the way.
I am by no means a master mechanic but i know how to turn my ratchet on and off and how to tell the difference between right hand and left handed vise grips lol.

But really i have been around , with the exception of engine building there isnt much i cant do and ive never attempted to build an engine cause a mic to me is something you embarrass yourself with when you get to drunk.
But i have no doubt about the engine swap , my main reason for being here is because after the fact i would like to know what to do with the v6 to get the most " reliable " power out of it , no boost!!!!!!!!

Ive heard swapping cams but i really want to know what else is out there that'll put a 1mz-fe at 250 hp or better.
I already know toyota ecm's are tougher to break into than ft knox so im planning on a piggie back system to get the most of what the engine already has to offer . dont question the motor i know people prefer the Jurassic 3vze but my 1mz was free ( perks of working at a junk yard ) so Be easy as i know my way around a car better than any forum .
Your opinions will be greatly appreciated.

So here is what i have
1997 corolla dx 1.8 my gf bought off the show room floor just hit 200k and still takes a beaten
Donor car is a 1996 camry le 3.0 auto 140k , complete car badge to badge , free99. (junk yard perks )

I am finishing up my explorer 1998 four wheel drive , trans went out !! go figure once my shops clear this is going in so i will be starting it in the next couple weeks , set aside 1000 usd just because the donor car was free so i can put a litte more dough into the swap.

Thanks for any feed back

:hi: Welcome to TN! Looking forward to reading about your project. It'll be like a Contour SVT, but better haha

Ford transmission went out, why am I not surprised.

I sure will , i am hoping it goes smooth and i think it will cause my resources are next to endless . I have about 10 of these in the yard at work and time is invaluable ,I am the kinda guy that'll spend 10 hrs doing something that should take 5. Its got to be perfect ( or hidden well )
Im going with the 1mz mainly because i know nothing about tuning or wiring . With a complete donor i plan on wiring not being an issue plus its lighter , power to weight is the only thing that matters . Brakes and handling come 2nd.
Like i said i have been doing some looking , about 6 months . Done a lot of creeping on here :nerd: . I think this is the most respectful forum i have found yet and is the only reason i joined. Everybody wants to argue and we already know mines faster than yours so it wont matter. :wink:
I will document everything cause altho there is very detailed post i have yet to see a step by step , from neg disconnect to reconnect . and none for the 1mz
I plan on it taking a couple of months as i work 12 hrs a day mon fri .
Thanks for having me and hopefully my navigation of this forum and punctuation will improve over the course. :laugh:

Since you have access to a bunch of vehicles, check the 2005 to 2012 Rav4, it's based on the Corolla and have a V6 option but you may lose power steering since it's electric and a difficult swap. But motor mounts and shafts and other bits may be adaptable.

Thanks I didnt think of that , this is why I'm here . I believe I have some rav's and also wouldn't a torrent or vibe ? Work if I not mistaken . I think The rav's I have are 1zz which I believe gm shared but i have a torrent i think with a 3.5 or 3,6 I'm not sure . will definitely look into it

You are thinking of the Vibe and Prizm. But they are compact cars and also Corolla variants.

Vibe and Prizm have a 1ZZFE or 2ZRFE but they're a 120-125 hp & 125 tq 1.8L 4 cylinder.

Some Vibe and Corolla trims have a performance engine, the 2ZZGE (1.8 L 160-180hp but 120 tq) or 1AZFE (2.4L but only 160hp but 160 tq)

GM made a vehicle the Saturn Vue that had either a Opel engine or a Honda V6 mated to a terrible transmission.
GM \ Isuzu and Honda made a vehicle in the 90's The Honda Passport / Isuzu Rodeo

subscribed...look forward to seeing progress. Good luck with the build. I've seen this idea pop up a couple times and yes, seen the video. Leaves much to be desired. Honestly, still waiting to see someone post a full progress build. I think the biggest hurdle is honestly the CV shafts. Mounting, which worst case, a good welder can fab brackets that will suffice. It definitely is not a drop in and go. To make it reliable, honestly I would say leave it stock. The stock power and torque increase alone will make the Corolla move out pretty dang quick.

My thinking in this regard is as follows:

1) The MR2 guys usually keep the S54 gearbox when they convert from 3SGE to 1MZ (the bellhousing pattern is almost identical)
2) Plenty of 3SGE conversions have been done in 7th gen Corollas using S-series gearboxes (and the diesels came standard with them)
3) Therefore, if I go for an S54 instead of an E153 then I can use 3 of the 4 mounts that a 3S conversion would use AND the same driveshafts (and not have to worry about finding E-series ones to suit)

As far as getting the most power out of the 1mzfe, they did make a TRD supercharger kit for the 97?-00 1mzfe.

Yea and thats why i cant understand how come more people arent doing this swap . When you look at the price of hp ? id be about 2500 in to building my 7afe to hold 250 hp . But yea im at work and i have no new rav 4 here . everything has a 1zz or 2zz. And i do plan on having to dissect the harness to an extent but i plan on gutting the donor car down and removing the engine harness and engine in one piece taking the ecu with it , beings that these cars have a hard wire set up , for lack of better terms , If im not mistaken they have a separate chassis brain box so all my windows and mirrors and lights should work fine once i take the ecm out of the corolla , im going to run the new engine harness and connect its ecu and then keep my engine fuse block in the car and just tie what ever acc into that. i expect to have to splice on different pig tails for things like alt and compressor . i knnow its not going to just plug and play . my biggest thing is i dont have the skill nor tools to communicate with the vehicle thats why im going with the 1mz cause from my understanding if i am careful i can take that engine . harness and ecu and pretty much that will run the engine i dont need anything flashed , electronically ive heard it will be easy even tho its obdII

Yeah i figured speedo is going to be a trick every one ive seen literally has the donor speedo gutted into the dash lol
and i do agree stock would prob be best i mean im only going to gain about 80 pounds as the 7afe is an iron block and i will be doubling the cars hr and tq i think stock these 7af motors put out 105 hp and 115 tq so i will notice the extra to pistons working lol. and i have heard horrible things about the longevity of the trd charger . im trying to stay away from boost .
anybody how well these 1mz engines do with a nice tune, is there anything to be had by running a good intake .exhaust and tune

You'll have better luck if you start a new thread in the 4th Gen Camry and Solara forum with the relevant info from this thread... or if the other TN Mods approve we could move this one there. :thumbsup:

Taking the donor car home today , sucks i have other things to finish cause i want to do this thing tonight!!!!
Need that damn ford out of my garage and put the fence up to make the wife happy . I bought the only yard in fl full of clay:crying:

But the car is going home tonight .
Do you think i need to change my stock fuel pump to feed the 1mz or just put an inline to assist it
 
#25 ·
It's not pressure PSI that's a concern, but flow-rate AT that PSI. So two pumps may both be able to achieve 45psi, but one will flow 100-lph and other may only flow 50-lph at same pressure. If you need only 25-50% more flow, additional inline pump is fine. If you need to double flow or more, then it's best to replace stock with bigger unit. Personally I like the Aeromotive pumps. Many go for Walbro, but I've found those to not be as durable or reliable (not to mention noisy).

Strangely enough, this rings a bell. I need to do some searching as I do seem to vaguely recall the 7A-FE pump being able to support 200bhp. Which has plenty of overhead for stock 7A-FE. But for 1MZ, you'll need larger pump of at least150-lph.

Yea i would be pushing it , maybe i can steal just the pump and craft something between the two .
The 1mz has pushed up to 220 hp , Really good day depending on where you get your gas but an honest rating would be 190 hp at 200 tq.
But i plan on a custom exhaust and doing a pretty slick cold air with it being higher compression i think 10:1? at 91 oct and a heavy right foot i might get 200hp and a small bump in tq .
so if i go on from there them the stock fuel pump will need to go .

It is a tight fit but as you point out the 3vz and 1mz are similar and thats been done i know off the bat i will need to make custom exhaust manifolds and get tricky with the piping , probably end up making 2 eng mounts and modifying the other two if needed cause ive seen they're close , was looking today . My imagination !! may be stupid but i was looking more at the sub frames to see if it would be easier to modify but i think i wasted my time even looking lol.
Im no master mechanic or fabricator But after almost two yrs at the junk yard with an usa and snap on truck twice a week , well lets just say ill be working here for a while so i have tools and can "take anything apart" Have a room mate thats retired country wielder of 25 yrs and may be pushing 50 yrs old but that man can lay down a bead . If i have to make an intake i will but i doubt it , My objective is to do it as easy and cheap as possible which im sure most people think the same . I want to be able to hand some one a book when im done and it be a step by step, pics and all .

And Uh " Yo !! If you need a swap kit Mounts ,exh, y piping I uhh might now a guy "

I want to see more v6 corollas With a power to wight ratio very close to the base model vette of that yr the infamous c6
1997 base model c6 345 hp roughly 3250 depending on options gives a p/w of 0.1062
1997 corolla dx removed of necessities with swap im guessing 2350 and ideally when completed 215hp which gives p/w 0.0915

With other tweaks like 3vz cams and good after market ecu port ,polished ... This thing could potentially Have some street cred .

Im not trying to be john force , I just want to shit on mustangs and make vette owners worry saying " Was that a F**king Corolla?"

The s54 isnt an option sadly , this car is still going to see hwy quite a bit , I drive 50 miles for work everyday at 70mph , thinking of doing something with the stock ones , maybe taken it apart at the joint and see if there the same size and make something . Its funny you bring this up cause im worried about the mounts and manifolds and my buddy said " What are you going to do about the axles ? lol

Well i hadnt gotten that far !!!

But if all else fails there is a place in lakeland thatll make you axles for about 250 a pc :(

Had a look at the ratios and the S54 is a bit shorter overall than the C52, however the S53 has a taller final drive so cruising RPM would be slightly lower than the 7A on the highway (which is fine by me) and an S51 is even better (the S54 is what usually pops up online in conversions because that's what the non-turbo SW20s have).
 
#32 ·
Yea I hear ya , 0 to 60 would be a little better as well i would think I believe 1st gear is shorter in the s54 . I'd like to be able to look around but i am going to work with what i have .
This Whole thing is to be as cheap as possible and the donor car was free 150k on the clock and i have the history . Car was a trade in and some dealers wont re sell them so they allow people like us to buy in bulk . Have a few car lots that sells us all trades They dont want given age looks or miles for $250 a pc ya just have to take them all. Goes to show what that mark up is on your trade:surprise:

We get some pretty good Stuff sometimes , ive probably Brought home 12 cars in the almost two yr This is the best job ive ever had . We dont get any health benefits or 401k But i get junk yard benefits !! I have brought home everything from a 1994 BMW 740il with 114k ice cold ac to the 1998 4+4 explorer currently holding this project up ( My wife loves my career Change too )>:D

If i had my choice id try to get a 5 spd But this car is my wifes and she bought it brand new with viper wheels and " Mystic plum purple " paint that i am currently trying to find to touch up. Supposedly factory color..
This car is her baby . I cant even believe i talked her into it But im glad i did cause i cant wait to get it done . But, i did just buy her a 2012 sonota gls ( junk yard perks , we are a tow / Salvage company Impounded it and owner never came and i spent 3100 with 96k. Her daily was a 2001 camry 4 banger with 244k begging for a bullet . Oil prices dropped when i crushed it
I Married into the toyota family ,Im a Ford truck/gm Sports car guy.. Not all of us are perfect

But back to it

I have been comparing axles at work and think i have a really good shot at making something work with using the Camry Joint housing ? idk forgive me i am not a mechanic But the shaft and housing that go into the trans look identical in size and altho i have never taken these two apart i have taking alot of cv axles apart and replaced boots and pretty much all of them look the same / similar So maybe i can use my corolla shaft so ill have no issue with my stock hub fitment or length and rebuild the axle using the camry Housings? So it fits trans ,Just an idea
Im not going to be doing much more than talking about it untill its done as i do not want to flood this thread with ideas that i cant prove worked . But im just trying to look at it from every angle i can to make this swap as cheap and easy for people to do .
Ive never done a " Non indigenous " swap lol I have a feeling thats going to be a new term

I think the taller e153 will do fine with such a light car and i do travel to ft myers at about 85 mph every now and then plus I hear better feeling shifts too

Sorry for being so long winded im still about two weeks out from starting it But my wife is probably ready to punch me in the throat and tired of hearing me muttering to myself in the garage .

Its your fault For all your acceptance and encouragement
