New fabricated baffle sump

looks like an FS5W71C gearbox. What kind of repair did you make to the extension housing?

Pulled the covers off the datto just after New Years Day and checked a few things.
( Mainly that rodents haven't set up house inside!)

Haven't really done much to the datto in the last few months as i still need to purchase a clutch, after market Harmonic Balancer and a new set of coil packs before I can place engine and gearbox back inside car.

I Got the gearbox repaired by a friend after knocking off the small lug that sits at the lowest point when i was taking the car off the trailer before i put it in storage. It removed just enough metal to allow all the oil to leak out but luckily not enough that it couldn't be fixed. I'm certainly no boil maker by trade but I asked how he did it, using a medium heat with a Tig welder and applying wet rags to the front and rear of the gearbox to help protect the seals, he managed to successfully weld a small amount of metal back into it and then cleaned it up as best as possible using a grinder. Whole thing only took an hour which was pretty good and only for $50!

Was very happy that i didn't have to fork out $500 for another used gearbox

Ah, fitting pistons. And it looks like custom main bearing caps.

Is that a harmonic balancer?

looking good.
I'm in the process of rebuilding my CA18 as well.
Started on my baffled sump today funny enough.
fun never ends with racing cars.

Yeah new Harmonic Balancer but It doesn't come with a pulley for the AC or power steering so if this was in a S13 Silvia I wouldn't be able to use it. Luckily it's in a little Datto and the only accessory belt I need is the one that turns the water pump and Alternator.

I've just been informed last night that we have a problem with the piston to bore clearance as we were reassembling the motor as its too excessive so unfortunately I have another setback. Definitely " fun" playing with race cars 😐

Haven't updated this thread recently due to time constraints but I am close to getting the car onto a dyno and hopefully back on track soon

Still need to wire in new gauges, tidy up wiring loom
Refit exhaust
Replace clutch slave cylinder
