probably tons easier than working on the original V6 too.

This too.  You can't even change spark plugs on the 3mz without removing the intake manifold.

I did it once without pulling the manifold. the last 2 were horrible

also being interrupted by "nesting"  about 2 weeks until baby is due.

 You have one of those as well?

yup, this is number 3.  Hence the van for kid hauling.

Twinsies....although we got the van before the second one. Mine isn't bmw powered though.

Definitely looking forward to watching this build enfold.

Ordered a bunch of Willwood parts for the clutch pedal setup.  I need to modify the brake pedal bracket to get a little room and move the pedal over about 2 inches and trim it narrower.  The reverse swing mount pedal is necessary because there is no room on the other side of the firewall from where the pedal needs to be.  The strut tower is hardly an inch away. 

The warmer day yesterday was nice, I got a couple hours of work done after the kiddos were in bed.  My wife's due date is tomorrow so baby is coming anytime.

I didn't even think about the clutch pedal situation. By the way the pedal bracket looks, the MC will be mounted inside the car with the fluid reservoir inside the car also, is this correct?

Hope everything is well for you guys tomorrow and if nothing else, that everybody is calm and relaxed.

The MC will be inside facing back, I ordered a -4AN bulkhead to get through the firewall and an adapter for the MC inlet to -AN so I can put the reservoir in the engine bay.  It would be a pain to check/fill under the dashboard.  So yes there are some additional parts than shown in the pictures.  There is a nice racing parts shop in town that ordered the stuff and has lots of hoses, fittings, and adapters in stock so I will figure some of it out as I go.  One thing I forgot is an adapter from M10 bubble flare to -AN for the slave cylinder.

Everything is going well with this pregnancy.  We are crazy hippies and having a midwife come for a homebirth.  We haven't done that before but neither of us is worried about it.  It is our third so not the first rodeo.

Hippies!

Another slight issue is that the radiator is backwards compared to the BMW one, as in the low connection is on the left and the high connection is on the right.  I have plenty of room to cross the coolant hoses in front of the engine which will solve that.  Also the Toyota engine has the "radiator cap" on top of the engine.  I plan to use an expansion tank and plumbing it similar to a stock BMW setup, I got a radiator hose temp sender adapter thing to install in the upper radiator hose but instead of a temp sensor I will put a nipple in the 1/8 NPT hole and that will be the bleed line back to the expansion tank.  Conveniently the stock radiator looks pretty solid, it has aluminum tanks too which I didn't know was a thing.

Could you just source a radiator from another car that has dimensions and outlets that you need?

If you'd be interested in a E34 expansion tank I have 2. Not sure what kind of space you have to work with but they mount on the firewall.

I might be, are those similar to an e32 style where it is above the engine on the firewall?

More pictures soon.  I got the clutch pedal/MC and a bunch of AN fittings to get through the firewall.  I got some 1/4" Cunifer tubing for a fuel return line.  There is no access door under the carpet so I have to drop the fuel tank, that should be exciting, it's about 3/4 full I think.  Yesterday after work I cut the CV axles off right by the outer joint so I could spin the cage sideways and get the balls and cage out.  I will be reinstalling just the cup part with the spindle to hold the front wheel bearings together.  They also have the tone ring for the ABS so I have a small chance of the ABS still working.

PICTURES PLEASEEEE 

[jc43089]

Perfectly good CV axles chopped off.

I might trim these off right behind the tone ring.

Not a ton of room trying to fit a clutch pedal.

And this is why I need a reverse mount, the wheel well and strut tower are so close to the firewall that there is no room at all.

Not the number one choice but you could cut an access panel for fuel pump activities. After removing the seats and carpet it may be a wash

I might do that anyway, for next time. I don't know exactly where the pump is or how close to the floor it is so I was concerned about damaging hoses and wiring. It looks easy to get out thankfully.

Those are the front axle stubs, correct?

You need to take the van to a toyota dealership when its done and have them do an oil change and get it on camera. We can crowdfund it

Yes, I did end up parting them off in a lathe .080 past the tone ring. I installed them last night, they worked great. I've thought about what service I should ask for at a Toyota dealer. The confusion would be priceless.
