3VZ crank same as 5VZ crank?

brad d · 04-09-2009, 10:50 AM

Will the 3VZ crank just drop into the 5VZ? I keep hearing that the 5VZ crank is cast.. and I also hear another factory toyota crank is forged that will fit in.. but it might need some work to just drop it in not too sure.. http://www.toyotacatalog.net/M1WebGe...4-10347ED856B0

"the 5vzfe crank is the exact same crank thats in the 3vze, the displacement increase comes from increasing bore size from 89mm to 93.5mm. yea, itd be nice if the 5vz had a stroked crank that we could just drop in, but that means a different casting, and thats just not toyotas style. although, they did make the 3vzfe with a forged crank, and that will drop right into a 3vze or a 5vzfe. i think the ultimate buildup would be:

3vze block-this is the strongest of all vz series blocks, it has 3 bulkheads in the valley between the banks that the other 2 dont, increasing block rigidity, as well as thicker webbing on the sides of the block compared to the 3vzfe and 5vzfe
3vzfe factory forged crank-strongest of all vz series engines
5vzfe heads with 3vzfe cams-all stock and 3vzfe cams have a bit more lift and duration
forged rods and pistons"

I need to find out what year of 3VZ came with the forged crank...

"3.0 Forged Steel Crankshafts

The factory 3.0L crankshaft is a cast piece. D.O.A. now has forged steel crankshafts for the 3.0L V6. We are the exclusive source for these brand new, Japanese-spec forged cranks. Please call us for pricing and further information."

They are just dropping in a forged crank from some year of V6 toyota..

well i found some info on how to tell
Sharp parting lines = cast wide = forged

sharp cast corners (not machined ones) = cast dull rounded corners = forged

brad d · 04-09-2009, 04:42 PM

Well... unless the pics poste above are wrong the 5vz i have has a cast crank...... it has the sharp lines just like the one on the lest in the upper pic.

Not my crank but another guys 5vz crank.. looks to be cast as well... unless toyota can make a forged one with a thin parting line... I will take a look at the Turbo MR2 2.2 stroker motor we are building to see if it has the fat lines

deucegirl03 · 04-09-2009, 05:35 PM

hmm its hard to tell. looks to me like the one on the left is cast for sure. the one on the right looks like its forged tho...
keep us posted and thanks for sharing this info! yay for learning!

brad d · 04-09-2009, 05:41 PM

the last pic shows a custom billet stroker crank for the 5VZ next to the stock one... I just need to find a close up pic of a 3VZ-FE..

With a user name like 3VZ-FE why don't you find/take a pic of a 3VZ-FE crank??? (I cant find one

)

OH and the ACL bearings for the mains rods and thrust washers is the same part # from the 3VZ-FE to the 5VZ-FE

brad d · 04-11-2009, 08:58 PM

Well I was looking at the MR2 turbo motor we have in the shop right now the 3S.. and it had the wide forged like parting lines..

I also found a 3VZ-FE in a camry at junk yard that you have to pull the parts your self (super cheap parts cranks are 30$) but its not going to be too much fun pulling that crank.

deucegirl03 · 04-11-2009, 10:23 PM

i thank you for this informative thread. i was curious as to the scientific difference between billet and forged, so i googled it and came up with the following link. short but informative. just for anyone else that may be following this thread like i have:

Billet versus Forged

U-235 · 04-14-2009, 07:12 AM

^That actually clears up a misconcpetion I had.

I thought that "cast" or "forged" in relation to pistons, rods, etc. meant the stock was cast or forged into in block, and then the appropriate part was milled out of the block.

Good to know.

Do you have pics showing the difference between the blocks? I'm seriously considering building this Frankenstein engine. So will the timing belt, water pump etc.. be the same?
