I have always been curious if anyone makes a stroker kit for the 5vz? Also if they make a big bore kit? The biggest set of pistons I have seen is .040 over.
just curious do they make a stroker for the 5vz?

Check LCE Performance, they might have what you are looking for. Pistons up to .60 over, forged crankshafts, etc... They have some pretty cool stuff for the 5vz.

That's the website I saw the .040 over didn't see the .060 over or a stroker il check again thanks

The .060 pistons were an option in the master rebuild kit, I didn't see anything about a stroker either.

I wonder if the .060 is really an option, I just noticed that the drop down menu for piston size lists it, but the description only mentions .020, .030 and .040.
A stroker crank would likely have to be custom made. If I were to go the custom crank route in a car, I'd call Bryant Racing
They are who the Teams I've worked on have used for crankshafts, for years.
If they haven't made one for the 5VZ-FE previously, they certainly have the ability to do so. It's certainly won't be cheap, though.
The 5VZ-FE is already essentially a bored out 3VZ-E block, so there's not a lot of material left in the block for boring. Unless you want to get fancy and sleeve the block. But I really think you're getting to the point of diminishing returns at that point, while spending a bunch of money to do so.
A TRD supercharger with supporting fuel, timing, etc. mods is going to be much cheaper, and might just be enough to satisfy you.
Or you could drop in a nice compact LS motor that's built. Of course the rest of the drivetrain will then need to be strengthened as well. Then depending on emissions laws where you live, getting over that hurdle too.
Lots of possibilities. It just depends how much you want to spend.

Eww a ls motor no thank you lol I already have the supercharger headers custom 3.5" straight threw exhaust running 10 psi. My plan is just to rebuild the engine fully forged later on down the road. For now im just trying to get a ideas what's available for the 5vz. My next and last mod till I rebuild it will be to modify my pulley to run more boost and a set of cams.

I have no idea I would have to talk to lce see what they recommend since im running the supercharger. 1000 $ is not to bad for cams when im done with my pulley mods I will probably be around 12 to 13 psi when I order them.

If you're looking at running that much boost, then I think you need to take the supercharger off and go with a turbocharger. I don't think you're going to get much more out of that roots blower. Other than a motor swap, I think a turbo is your best bet for more power.

Yup that's the plan my uncle and I are going to build the turbo setup he has a 1400hp 6.6 liter mustang cobra that runs 8s in the quarter mile and im a machinist / professional welder I have a lot of exsperice fabricating. But im broke right now no money for a forged engine or the turbo setup for now just trying to get ideas and seeing what's been done before on the 5vz. My friend has a fully built forged 5vz with oversized valves cams everything and bored .040 he said it revs to 10000k. He has a custom 1.1 pulley grooved and custom grooved belt running 16psi of boost he said it can slip at all. He spent 8 grand on the motor and makes 525hp at the crank and 480hp at the wheels.
Dang.. 10 million rpm is impressive..

oh my..
Eat shit guys next time I see him I will take pics and get pics of his dyno pulls and start a new thread so you can all see that this motor is real.

Just for the record, the only thing I was commenting on, and it was intended to be a joke, was the 10000k comment.
I knew you meant ten thousand rpm.
So that would be expressed either 10,000 or 10k.
10000k, is ten million.
Have a nice day.

I know it was a typo just tired that no one believes me about this motor and all the spell check police getting off topic.

Because you're not the first guy to hop on this forum talking about some buddy who has a 10,000HP 5vzfe. It's highly suspicious considering that your "buddy" who "says" he's running 16psi would be so far outside of the blowers efficiency range, there's no way he's putting down 525HP at the wheels.
But if it's out there, I'd love to see it.
