2j + 3s = Homebuilt Hybrid, My Motor Assembly pics

Thanks to some sharp pricing, generous donations, and a MEGAMEET sized care package - i am pleased to be able to reveal the following:



Thats:
1 x 3SGE Manual Longblock (80K old)
2 x 2JZGTE pistons
1 x set Big end Bearings
1 x Headbolts
10 x sparkplug
1 x main bearing shell
1 x engine gasket set

looks like tonight will be spent stripping that motor and cataloging unrequired spares (i.e. the entire bottom end bar the block!)

Project is back on!

Once i had picked myself up off the garage floor after the epicness that was death by retardation, it was time to get back to making this bloody thing work.

Within a day i had the motor completely stripped down, block, head rods and pistons away getting cleaned, crack tested and measured prior to reassembly.

The rod that was in number 2 cylinder was found to be twisted by around 4mm, so into the bin that went, and thanks to a friend i managed to source a replacement rod, but i needed some way to balance it. So i made up this wee jig to hold the rod at dead set level so i can weigh each end of the rod as accurately as possible. Calibrating it with the previously balanced rods to get it even before i went and put on the new rod. Worked a treat, and can balance a rod end to within a 10th of a gram




Thanks to the previous failure, where valves met pistons, it took all of the guesswork out of how much i needed to enlarge the valve relief's in the 2JZ pistons by. so to make doubly sure, i inserted plasticine and timed everything up.

How not to do your timing belt on a stock motor.....


then stired a few times over, nice and slow. bring back to TDC, remove timing belt, cam gears and head, and we have......

After measuring to the edge of the valve indent, close to around 2.5mm clearance is achieved. and that is taking into account stretch as well. i may or may not have requested a little more than required to be taken off the piston to achieve that measurement. But after what happened last time, you cant be too careful.

So with that, the whole dummy assembly was stripped down and cleaned for the last time (I have lost count of how many dummy assemblies i've done on this thing. Certainly done more than my fair share of cambelts) and now full assembly can happen. Nobody really wants to see full assembly pics in detail, so heres the brief ones.

Head on and torqued down, cams also


Motor fully assembled and ready to go back into the car



Guess i should pull finger and get it in the car huh?

yeah man. I cant wait to see it going

Ah nice work man good to see you back in the game after what happened!

Good luck!

cheers. Took a bit longer to build than i expected (spent too much time doing motorsport related activities ) so should hopefully have it fired up in the next couple of weeks.

Good stuff Andrew! Can't wait to see this all done.

Awesome setup for weighing the rods too

lol, dunno about awesome, is a wee bit rangi, but got the job done.

good stuff... soon there will be no need for pushing........
