the rear flare came up looking pretty good, but the front flare looks like it come out straight rather then flowing down like the rear does.
 
so this is how those ebay ones from QLD look when you try and fit them tight. looks like the fronts needed to be lifted higher and not pulled so tight at the ends.

Bought a tow car!

Bought a new toy and brought it home yesterday.

 
I've been wanting one of these for years, and finally I have one. A 2 post 3500kg hoist to go up in my shed!

And I finally brought my 1MZFTE out of storage and back to home.

So with a good tidy up in the shed, maybe I can get back to this project!

I've had a pile of parts building up in the shed for a few months now, so I thought the 3 day weekend would be a great time to start putting them into the car!

Drained all the blood.

36" lift kit fitted on the rear.

The last engine drop I'll be doing before the hoist is setup.

Engine is on the ground, just need a couple of small components and the project can kick off.

While the car was lifted, I decided to drop the tank and pull the fuel pump out. Going to throw something bigger in to future proof the fuel system.

While I'm waiting for a few parts to turn up for the 20V, I decided I'd do some paint work on the V6.

This turned up in the mail on Monday, HKS GD Pro twin plate clutch. Should handle any and all abuse the 1MZ Turbo can throw at it.

Sometimes I do stupid things, this was not one of them...

Do you plan on boosting the 3mzfe in place of the 1mz?? I'm not entirely sure, so please take it with a grain of salt, but I recall those motors having an awkwardly long stroke, so they dont like to be revved, and the rods aren't the best. But nice pickup, ive been waiting for someone to use the 1mz's big torquey brother.

3MZ has the exact same 83mm stroke and even shares the same rods as the 1MZ, it just has bigger 92mm bore pistons. According to the internetz, they also share the same problems as the 1MZ's pistons, that where the valve relief drop into the side wall of the piston and produces a weak spot towards the top compression ring. Generalisation suggests around the 300RWHP mark, the stock pistons start failing, while the rods seemed to fail around 500RWHP (WTFAuto was able to bend a few at figures over this).
 
With the 1MZ I was going to use some modified forged 5SFE (5SGTE) pistons as advised by Tristan @ WTFAuto as a replacement for the stock units when they fail and 22R rods can easily be made to fit the 1MZ for when/if I ever went chasing 500HP. However with the 3MZ having a 92mm bore, I cannot find too many piston options, the closest I can find is 22R pistons which is 92mm and has the 22mm small end, but I don't know if deck to small end distance is the same or if the valve clearances / compressions are remotely compatible. Hopefully a bit of research should give me the answers I'm chasing (other wise it might be time to ebay some 22R parts).

Yeah, after I posted it I checked and found I was wrong. 92mm pistons is getting into subaru territory, but subaru pistons arent exactly great.

The EJ205 has 92mm pistons, but uses an odd sized 23mm wrist pin. After scouring various parts of the internet, it looks like Mitsubishi 6G72 pistons may be pretty close to fitting.
 
The 6G72 uses 92mm bore pistons with 22mm pins, a compression height of 32mm, a -14cc dome (Wiseco) and a 48cc combustion chamber.
The 3MZ uses 92mm bore pistons with 22mm pins, a compression height of 31.2mm, a -1.7cc dome and a 56.3cc combustion chamber.
 
According to Victory Library, to bring the 3MZ down to 9:1 compression, you need to add an additional 12.67cc to the combustion chamber (68.97cc). Using the 6G72 pistons -14cc dome and 0.8mm higher compression height will put the combustion chamber at ~65cc, setting the compression ratio at ~9.5:1, pretty much the place I want to be if I'm adding some boost to it. A slightly thicker head gasket might be useable to bring the compression down to as low as 9:1 if t's really needed.
 
Another bonus is that the 22R rod has the same small end width as the 6G72 pistons, so it will only require machining of the big end width down to 16mm to suit the 3MZ crank.
