Hi Guys, I thought I'd add some info here.

You can get stroker cranks for the 1FZ-FE. They either come from Revolution in Dubai of from here in australia. (approx $6000 aus + shipping)

You then also need custom (shorter) rods to go with the crank - generally another $1000 or so. You can use a rod from another motor, but you need to buy pistons as well.

Basically, you won't get out of it for under $10,000 (and that's just the bottom end) Consider also that this will only net a 300cc increase. There have been bigger stroke set-ups than that, but the rod angles and rod length to stroke ratio gets all nasty

There are two bang for your buck ways to do it.

1. The 1FZ is very under stressed, and flow increases in the head of 30+% are not dificult. In addiditon, the cams are very conservative and of a very low lift (330 thou only). Cast iron blanks are available so you can design your own profile, or just go for an off the shelf grind. The only thing to remember is that anything over factory lift required some relief of the cam bucket bores as bigger lobes are an interference fit. You can then also go to bigger valves etc etc. When doing this stuff the bottom end can remain 100% stock. One thing to watch is that the porting needs to be done by someone experienced as it is east to have the flow rate go backwards if you don't know what you are doing. The only reason that pinging occurs is if there has been no attention paid to gaining control over the fuel and ignition settings.

2. The 1FZ is extremely strong in stock form and can withstand turbocharging with only minor mods. First thing is having the block and head freshley machined flat with a good surface finish, and then using ARP Toyota 2JZ head studs with a fresh gasket. The factory pistons are very good for turbo applications due to high mass/long skits/thichk crown and ring lands. The 80 series are best with the 100 pistons series being a bit lighter. The conrods are good for 600hp reliably. The only rod that has failed on me was at 850hp. (pistons were fine-just the rod collapsed). The crank will support as much HP as you choose to make. (ie 1200+++ hp. They do not break) As with head work, to make the most out of a turbo, you need to gain some control over the fule and spark, although at 10psi and under the factory system copes okay with a few tweaks.


In short - do not bother with a stroker. They are absolutely rubbish bang for buck.

Chuggy at Crankshaft Rebuilders were doing crank regrinds to suit the 1 fz taking them to about 5.2 lt early days when I had my turbo one, that wasnt anywhere near the $ figures mentioned here.

They were doing Patrol cranks as well.

Does anyone know of a machine shop that knows what they are doing to have a head machined to gain more perfomance, i am looking at a head reco and wouldnt mind a bit more power/torque with the duel feul and then get the uni-chip tuned in for the head work.
would look at keeping the stock cams th, have heard ppl having proplems with the cam bucket like said in willy hiluxs post
