Hi,
First, I want to thank Effjay76 for findingthe right a possible clutch disc for the H55F/ in his thread here 1UZ mated to a 4 speed. But I've come to the conclusion that clutch will eventually destroy the input shaft. I am creating a new thread because I just realized it's probably rude to hijack his post.
Now a big, fat warning for anyone thinking about ClutchXperts SPC or CXP clutch parts on amazon and ebay. They are selling clutch parts for a Supra, which are 9.25" for the 5VZFE, 9.75" application. See thread below what they are pawning off. I'm in a dialog with a 'Head Manager' by the name of Jason S. after they shipped me the wrong pressure plate, they are now saying I must have a different engine, and I'm dealing with a swap, and Jason is assurring me this is for the 5VZFE. Well, I have a ruler and pictures which I will post below. If you are getting a pressure plate and disc from them, it will fit once you drill the locator pin holes, but you will have 20-30% less clutch surface will actually make contact with the flywheel. It's funny that Rock Auto, Exedy, Kupp, FX, ClutchMax and everyone else show the 5VZFE as a 9.75- 9.84 (250mm) clutch disc, but not ClutchXperts. I applied a little heat to the sticker to peel it back a bit and this is a Exedy TCY715 pressure plate that they have applied a ton of yellow, then black paint on. Now their communication has been excellent, let's just hope they can admit someone screwed up. I'll update as I learn more.
I have all 3 engines for three different applications.
A 2UZ-FE into a rock crawler with the H55F (I have both the transmission and the 2UZ-FE)
Two 3UZ-FE, one into a daily driver with the H55F
A 1UZ-FE turbocharged with a 2006 350Z 6 speed transmission (CD009/A) mated to a Landcruiser FJ55 rear axle in a 1978 Toyota Corona with a speeduino running it:
Engines:
To compare, the 3SGTE from the gen2 MR2, 1992 is 232HP,224FtLbs
Given that, the stock pressure plate of 1820 Lbs will need to be upgraded. I have a friend at work who is a drifter and worked for bully dog telling me the clutch disk is not the primary key, it is the pressure plate, but when you think about it, it has to do with surface area vs. clamping force, and if you get the same force on a smaller surface area, your friction goes up hence the puck style clutch discs.
Now for part numbers I can verify and know about.
First, the flywheel.
So far,three two possibilities.
The 2005-2015 Tacoma 4.0L V6, which has a 10.75" disc, same as the Land Cruiser. I'm trying to get a used one from the local clutch shop to see fitment. This is ideal, because this engine had the bolt-on factory supercharger and puts out close to the 3UZ. The ring gear will need to be R&R, but it looks like the ring mount surface might be the same as the 3.4L. Way the heck too big. The ring gear leaves about 0.100" if it were turned down to fit. Big disappointment, that.
The 2004 Tundra 3.4L V6 5VZFE. This one works with only the hole egg operation! The catch is the original automatic ring gear plate is retained and this flywheel slides on in front of it. This gives you both the original spacing for the starter AND gives you close to 10" clutch disk diameter, since these took 9.75" discs.
The total crankshaft bolt dept: 22mm crank surface to bolt bottom out. Spacer plus flex plate measured with dial caliper: 29mm. Clutch thickness ~12mm. So ignoring the flex plate and spacer, say they are 34mm, or 1.33 (1.25-1.375). M10x1.25.
Part numbers:
Perfection Clutch 50-135 (from Rock Auto, the one I confirmed fit with), $41
LUK LFW199 $57.79 (Rock Auto Price)
Brute Power FW9135 Autozone $86
Pioneer FW-322 Autozone $152
Sachs NFW6939 Autozone $86
This larger flywheel opens up more options. I no longer need to modify the 350Z clutch disk, there is more plate area and I need all I can get.
While we are here, the flex plate is 3210150010 for the 3UZ. Looks like the same number for the 2UZ.
There are three considerations, the gear pitch, the outer diameter, and the distance from the crankshaft.
I bought one from Oddesy fab: 1UZ 2UZ 3UZ Manual Transmission Flywheel
It was $275 delivered to my door. I also bought a flywheel off rock auto for $50, the LUK LFW196, from a 1990 Toyota 4Runner 3.0L.
I am 99% sure Odessy just milled this flywheel (which is what I was already planning on doing before this came). The inner diameter is a perfect fit on on the crank.
The hole diameter is about .062 interference fit hence needing to egg the bolt holes which I will do with a 27/64 end mill. I don't know why it is not metric, but this endmill is a perfect fit.
Other suppliers of this flywheeel are
XAT OEM Style 1UZ V8 Flywheel (per Effjay76), and UZ to CD/JK Swap Components.
the latter I bought the bell housing adapter from to convert to the CD00A. They claim their flywheels are machined from billet, and I believe them. Their adapter is very nice. I don't know if the flywheel will fit a H55F application.
The Pilot Bearing
For the H55F/H44, A 6002 bearing fits perfectly. Theoretically you can pack grease behind the bearing then use a tight fitting bolt and tap it through the center with hydraulic pressure pushing the bearing out. For the CD00A, I just ordered some 6804 (32x20x7) sealed bearings and I will turn a steel bushing for the input shaft, since it is 15.4mm.
Clutch Disc
I found someone that can make this disk shipped to me for around $235. I contacted Brandin over at California Clutch (brandinedwards@californiaclutch.com) who said it would be about a week lead time. I will go this route since I don't want to destroy my imput shaft with the Jeep application ( see below). I just have to let him know what I want. Nice to have someone that can do that. Please speak up if anyone knows of someone else.
The clutch disc is a crown J8132577, it and slides on the shaft. JCWhitney ebay store is the cheapest place to get it, $86& free shipping. Jeggs is $79 but $20 shipping for $92.
I can confirm the ACT 3000801*DOES NOT* fit, even though it is supposed to fit a 80-83 Jeep cj5 2.5L.
The stock 350Z clutch disc works for the CD00A (M-PACT 99688-D) from rock auto, however it is about 1/4" too big to fit in the 98725. I'm going to order the ACT T023 and see if that 350Z disc will fit. If not, I get to find yet another disc. I'll just use the 3.4L flywheel/clutch.
Now that I bought 3 of those J8132577, I started looking at the splines, and the reason the ACT doesn't fit but this one does is that it's a little smaller diameter. However, the big issue I see is that the tooth profile does not match. The Jeep application is square while the Toyota is triangular, which means the clutch will be wearing on a point on the input shaft and will eventually destroy it, since the corner of the tooth will be hitting the sloped section of the input shaft, so now I'm looking at potentially taking the center (which is just riveted) from the Toyota disc and mating it with a disc that fits the flywheel. I'll have a look at that Kupp disc and see if I can convert it. If so, that would be a nice way to go for $115 plus some sweat equity. It's not super critical that the clutch disc is perfectly balanced, since it slides in the pressure plate anyway and the little bit it might be off should be insignificant compared to the flywheel weight.
The pressure plate (5VZ-FE): This engine produces ~190HP and 220FtLbs torque.
I have no idea about any of these plates, but I'm going to buy one so I have it for fit.
SPC-XT56035TTNDHP5-CC - Stage 5 with only 2100lbs Clamp? 389HP, 359lb-ft from SPC, whoever they are, $80 to my door. THIS DOES NOT FIT! See above and below.
The pressure plate(MR2):
I figure I need (1820/224)*320 = 2600 for the 2UZ application (stock MR2 1820@224 vs x@320), so according to the chart below, ACT extreme would be needed for a 2UZ.
I can confirm that the M_PACT 98725 pressure plate fits the LUK FW196 flywheel, which I bought so I have something to play with.
I also called M-PACT, and they did not have info on the 98725, but said typically it's 25% more than needed by the application.
They did say their 98725-HD is 2200 lbs.
I've found other forums who say stock is 1820 per ACT.
A recount from here:MR2 Forum
3SGTE stock 1820lbs (confirmed with ACT)
Exedy Stage 2 2090lbs
Competetion Clutch Stage 2 to 5 2200lbs
ACT HD - 2400 lbs clamp load (confirmed with ACT) T023
ACT Xtreme - 2800 lbs clamp load (confirmed with ACT)
ACT MAXX Xtreme - ???? lbs clamp load (ACT support desk couldn't give me a figure )
Looks like the KUPP stage 4 will handle the 2UZ, and it's a lot cheaper than the ACT T023 pressure plate alone.
Kupp Racing 4560294, $115 from ebay KUPP STAGE 4 CLUTCH KIT FOR 90-93 TOYOTA CELICA ALL-TRAC 91-95 MR-2 TURBO 3SGTE.
I can confirm the KUPP Stage 4 clutch kit for 9093 MR-2 turbo 3sgte (Horsepower Rating: 435 HP / Torque Capacity: 419 ft/lbs) DOES fit the flywheel.
Bell housing.
For the 1978 Toyota Corona, I already have the adapter from Pursuit of Perfection to fit the stock CD00A. All other applications want me to cut the bell housing off a brand new transmission, which I find pretty idiotic.
For the H55F, my current plan is to use the bell housing from these guys:
W55-58 Bell Housing
and build an adapter plate from the W55 to the H55, since the H55 appears to be about 3/4 inch longer shaft, so the plan is to use a piece of solid steel plate and align holes.
I have this adapter, and it is one hell of a heavy duty adapter. I have no doubt it is up to the task.
I just wish I had the front part of a W55,56,57,58, or G52 transmission to play with parts. Woo-ee. I bought a 76 Corona with engine/tranny on the side, and the transmission just happens to be one of these.
ECU
Speeduino. This is what runs many,many 3D printers. It has a ATMEGA2560 embedded controller. This has a breakout board/pin out is universal and cheap.
$20 ELGLOO Mega R3.
You mate this to a 'hat' from these guys:
UA4C
UA4C is the USA made board you want and you will need the mini-max-A2 signal conditioner that converts the hall effect position sensor to digital.
MiniMaxA2
I also advise getting the 36/2 wheel either from Toyota P/N: 19315-50020 or the junk yard - it is a lot more accurate for the pre-2000 1UZ engines. The 3U2/2UZ already have it.
I will say that if you pull one of these engines, be sure to get ECU, key reader, key immobilizer, and the key. If you don't, you are likely looking at a Speeduino because the immobilizer for the ECU is hell. Supposedly someone in russia can help you out. Heh. I got the speeduino up and running on the 1UZ in 2 days. I'm still trying to figure out the 3UZ that I have all of the above for besides the key. I will likely have to pull an EEPROM on the ECU to enable new keys.
My Speeduino site is here for software for the speeduino:
Speeduino Build
I may do a coil-on-plug for the 1UZ, and I will update the site above with code and info if I do.
I will update as I make progress, very slowly I might add.
