View Full Version : V6 Flywheel Solution.
Yes folks, our UK flywheel problems are over. You won't need a pocket the size of Alaska and you wont even need to leave the country to obtain one.
Myself and Tony (FourVeeSix) have modified a Celica GT4 flywheel for use on either 3VZ-FE or 1MZ-FE engines. The mod will also work with Mk2 MR2 Turbo, Mk2 MR2 N/A and Celica N/A flywheel, probably others too.
Was doing a webby, but just had a crash and lost the lot ARGH!
Still, here is a quick(ish) how to and some nice juicy pics.
As you can see in the first pic, the holes were elongated toward the outer edge using the center section, cut from a Camry flex plate, as a template and guide. The whole thing was clamped down firmly and milled from the rear face.
The bolts (part no. 90105 10207) were selected for their long shank, for higher shear resistance. However there are four minor problems with these bolts.
1. The shanks stick out past the fly rear face
2. The heads hang over the original bolt holes
3. The edges of the bolt heads interfere with the machinework on the center fly section.
4. They need to be cut down as they are too long.
So we ground down the outside egde of the rear flexplate spacer from a Camry (3VZ) until it fitted inside the center fly section on the outside fly face. This not only solves three of the four bolt problems at once (namely 1-3), but also adds a little extra strength and a better "clamp up" to the engine boss.
Problem four is obviously as simple as taking a hacksaw to them. You need to shorten them until no more than 10mm of thread is sticking past the rear fly face.
NOTE : Make sure you don't shorten the bolts until you have machined and correctly fitted the spacer plate (dead flush) on the center fly section! We found a handy nut that aided us in gettting a straight cut, the correct length and also it helps to clean the thread up when you remove the nut.
The rest I think is self explanatory from what you can see in the pics.

Another thing to note is, re-balancing is not really required as you are removing material from the center section of the fly, which carries little to nil inertial force, but you could get this done fairly cheaply if you really feel you need to. Also there is a little alignment nipple on the spacer plate that either needs linishing off or set to face outward for an even clamp up.
(Peebs and FourVeeSix, then go on to prove that black is in fact white and white is in fact black, then promptly proceed to get killed on the next zebra crossing)
well done matey, great easy solution. can i ask did you use a mill or drill.. and what type of cutter?.. tis my trade im just curious! .. is it a mod folks can do relatively themselves.. will give me clean break off work thats for sure :mrgreen: :pray:
We used a high quality drill press (pedestal/pillar drill) with the table wound up to max height to eliminate any sideward movement and the cutter was a suitable sized milling bit. Although I am a little reluctant to suggest that anyone could do this at home with access to lesser equipment.
However if anyone would like us to mod a flywheel for them we would be more than happy to do so. It's not that we are superior beings just the fact it requires more than just a little thought and technique. If not done correctly the results could be disastrous, as I am sure you are aware Adam.

Phew! Good job I didn't chuck that little spacer plate away then!
Just waiting on my turbo flywheel and then its off to the machiners :)
Just wondering whether it'd be worth filling the old "holes" up with weld, then grinding the excess off or am I worrying over nothing?

Or maybe mill a larger hole and insert an excentric spacer?
O.S.
We did think if that too Jiff, but cast stuff does not weld that easily and the local heat created may even cause hairline cracking to occur.
totally agree peebs, im no stranger to nibbling half cuts on a milling machine, thats with solid locked axis and a good quill!.
i have a mill, so i wouldnt attempt it on a drill. but it's certainly achieve-able with cast iron bieng a free cutting material.
i'll re-inforce the fact that if its a 240v 1.5 amp machine mart bench drill.. it would rip the drill apart and throw your job about!
but if you have a proper pedestal / pillar drilll, with some guts in it. a nice heavy clamp like peebs has .. and a nice milling cutter, its certainly achieveable.. the good thing with cast iron is.. this mod will go on the half cut, be it a steel flywheel, it wouldnt have touched it without major bone shakage and jumping!.. dont you love cast wheels now :boogie:
did you cut with flutes or face peebs? i'm guessing you cut with the face as its clamped
Hehe, yeppers. Thought about it weeks ago, only wished I'd had the confidence in myself at that time to try it then. You are definatley spot on when you say it cuts easily, that was the part I was worried about, but I would'nt try it with a normal everyday drill bit as I reckon runoff would be a real problem.
Yes adam, it was face cut, I could post a pic of the bit tomorrow if required.
he wants to show us his bits 8O ...
folk might like to see for mod.
im allright ..ive seen it all before .. :pumped:
i love jobs like that, where your sweating soo much the chips stick to youre forehead and burn :mrgreen:
LoL, wasn't that bad in fact adam, we used loads of slurry so I spose that kept chips down to a minimum.
Pics of my bits to follow shortly.

nice work peebs, you been re-reading or watching hitch hikers guide again while doing this work per chance !
I might have been. Then again I might have been eaten by the ravenous bugblatter beast of traal as I seem to have lost my towel today.
just the towel eh peebs :hmm:

yeah but at least he aint got 2 heads ! (was watching the original series the other day and couldnt stop larfing, its so funny to see how they did the effects back in the day) !
TBH I didn't go see the new one, it looks a bit crap to me, old one rules
...and here is that piccie of my bits I promised you all
(actually it's better than that, they are Tony's dad's bits in fact)

that be a 4 flute end mill. nobad!
Yeppers, sure did. Was actually quite a bit easier than we had anticipated, methinks.
btw adam
that be a 4 flute end mill. nobad!
I realized that and meant to mention it in post, but I could have sworn it was a face cutter we used. Lol
We reckon we have a poltergeist anyways as you can put a tool down turn away, turn back and its gone - for hours, hehe.
Just a quick note to make on this mod peeples -
If you are using an NA gearbox, you will need to use an NA clutch and flywheel.
If using a turbo box, you will need to use turbo clutch and either a turbo fly or celica gt4 fly
There may be other flys/clutches that will work out there, but the reason for difference is, NA has 20 teeth on clutch spline and the turbo/GT4 has 21 splines.
As a general rule, use the clutch and fly that matches the gearbox you want to use :)
okay, sorry if this has been covered, but:
the only alternative to this mod, in my case of using the MK2 NA gearbox with the 3VZ is to buy a 1MZ-FE fidanza flywheel which will, as they say, cost a packet?
EDIT: or of course an toyota OEM 1MZ-FE fly or perhaps a 3VZ fly if they have them? (i once owned a manual 1MZ camry, so they must exist!)

Thats the whole point of this mod:
Here in the UK, we never got a manual camry; Trying to obtain a manual flywheel camry from toyota would be like trying to plait sawdust and then being charging silly amounts of cash +vat for the priviledge. ( I recall a figure of around ?500 being quoted).
We do have the option of obtaining a fidanza flywheel however, we have to ship them from the states, at a rough cost of ?250, plus 2 to 4 weeks shipping delay.
The whole idea of this mod is that it's much cheaper and easier for us UK swappers to acheive. :)
haha good analogy. you UK boys are lucky to have some local knowledge and forum support happening, it doesnt exist here. thus i have to sift through all the international differences. ill have to see what toyota want to charge locally. thanks jiff!
jaemus I have seen a manual camry slip through my fingers with a 1MZ in it but sofar I have not come across a manual camry with 3VZ. however toyota do have parts numbers for all of the ECU's. I do think they exist but may be difficult to find.
interesting. quite possibly, just like in the UK, there werent any manual 3vz camrys.
I think I'll be giving toyota a call soon to find out if there were infact any manual v6 camry's in Oz with 3VZ engine.
Im pretty sure ive seen a couple on Ebay.
Thye just are few and far between because camrys are old peoples cars:poke2:
What year did the camrys Down here change over to the MZ?
i havent confirmed it, but afaik its 3VZ right through gen 3.
seams to have been 7/95. Thats the youngest of the 3VZ ECU part numbers I can find. So it would make sence that they changed the engine then. It looks to me thatt if you find a camry built between 4/94 and 7/95 then you will have a 200hp engine. If you find one from 11/92 to 4/94 then you would have 188hp. Thats just an estimated guess based on some toyota part numbers I have.

Then there are Definitely manuals down here:thumbsup:

that means the '96 camrys could be 1MZ. i think gen 4 started in '97.
yeah I dont know what year each camry changed its shape but those are the dates I was given. It should be evident though by the cars code. VZV10 for 3VZ engine. I believe the next model was SK20 for the 4cyl so the v6 one should be MZK20? but going by what you say there may be a few VZK20's out there. no idea really and I'm just guessing on the actuall codes aswell.
Just saw a thread that reminded me to post this.
For this fly mod to work correctly you need to use a spacer that goes onto the front of the fly face (gold plate seen in pics). This is because the bolt heads catch on the the lip nearest to where their edges go. Of course you could always just grind the heads down a bit, but the plate will also help to even out the grip on the fly face and give a firmer hold on it too.
The ideal spacer comes ready made, almost - just needs a bit taken off the circumference, for you...you can use the thicker (gold) spacer that you will find when you remove the flexplate from an AUTO Camry crank boss.
Happy modding.

yep i do this on all of mine,take the v6 spacer,grind it down a tadge and it works perfectly with a set of mk1 4a-ge flywheel bolts ,no cutting down of bolts required. <priceless info that! :)
nice one peebs for bumping this back up, will have a good read and see if I can work out what I need to do with my flywheel.
Oh and hope I actually have the flexplace spacer with my block

Am getting "PWP 404 error, this page cannot be found" on the jpeg images. Is This just me? if not can we have a new link. Cheers
If you look at the date of this thread, you'll realise why. What information are you looking for?
The Toyota Part number for the 1MZ/3VZ manual flywheel is : 13405-62020
Requires a Turbo Pressure Plate.
