I took the Sportivo box and a five speed to a gearbox specialist to get the .725 top gear set put in, and a 4.312 Torsen Diff. The gearbox guys got my instructions wrong. I told the boss I wanted the 4.312 diff, and if the five speed one wouldn't fit to call me 'cause I had a six speed that could be cannibalised if necessary. Went in today and the top gear is changed and the torsen diff is in but needs six speed parts to change diff. Needs the longer output shaft of the six speed. The actual gearbox mechanic said boss didn't tell him I wanted the ratio - he'd already put it all back together.
 
The list of bits I gave them is a coupla posts back.
 
Gearbox mech quite good, said toyota had bodged the 54,000k gearbox warranty repairs on the Sportivo box by crushing a race, so one bearing replaced.

Also went to pains to make sure I had manual conversion bits. That I wasn't trying to connect the SMT to it.
 
So now pulling the 1ZZ six speed out to sacrifice to the build. They're going to have to split the Sportivo box again.
 
Detail: The knock sensor - up behind inlet manifold - I have an early Celica ECU coming because of the higher rev limit (8200 vs 7800 RPM) The '02+ 2ZZ attaches to the head with a bolt and a pin so it hangs off there like a dangly bit. The 2ZZ 2000-2001 is a 1-wire straight screw in and requires a matching year 2zz ECU with the 8200rpm rev limit. My motor is a 2005 with tag type knock sensor, but on removing it, it has a fatter base thread the same as the 1 wire knock sensor, so they are interchangeable.
 
KNOCK SENSOR Torque: 39 N·m (400 kgf·cm, 29 ft·lbf)
 

 
ECU Part Numbers:
Stock '02 1ZZ Spyder : 89661-17680

(Part# 90105-06293, make sure they are the new TAPERED bolts)
 
 

 
Gear linkages going in... (top two cables in pic) gearbox unfinished. Gearbox guy going on holidays till 11th, but promises I'm first cab off the rank when he's back. So will work on getting the linkages, clutch master/slave in place ready - for now. You have to cut the hole behind the seats for the manual cables.
 
 
That top engine mount... scale it from yr bolt holes...

 2zz has baffle under crank, 1zz half way into sump.
 If your pickup fouls, try http://www.spyderchat.com...1zz-oil-pan-to-fit-2zz
 Be sure to totally clean away any residues/debris/particles after as they can be engine killers.
 
Then there's that clutch template no one seems to have:
If seething with doubts, guesstimate the bottom hole closest the booster, and try your pedal from inside to see if all three bolt holes line up. If not slot the bulkhead hole to where it needs to go and do the rest from that. "template" matches raised section of bulkhead.
 

 

 

You don't need to cut any material out of the 1zz oil pan to fit it on the 2zz.

If you are lowering the oil pickup, I believe you do... ;)

It would not go on, even without the lowered pickup. Sat 5mm proud no matter what we tried. Now it goes on without problem.
 
Seeing I'd read claims both ways - it fits, it doesn't - we did try fitting without modification first.
 
Anyway, more baffled than it was before. :-)
 
EDIT: Wish I'd seen this before I cut my pan. So simple, and such a tiny cut if you do need it!

That's weird. Might be more than one variation of either 2zz pick up or 1zz pans

So much waiting for parts and outside work.
 
Just got the C64 Sportivo box back today with .725 top gear, 4.312 diff, LSD, and MonkeyWrench shifter bits installed.

I only cut a 3mm wedge out of the top side of the pipes at the manifold flange before welding back together. Now that I can assemble it I can see 5 or 6mm might have been better (more suspension cross member clearance) but this can still work. We'll just have to curve the first section up immediately. If I put a straight pipe on it just touches on the side away from the headers.

Got to doctor up an inlet and get the axles back in, fill with oils, all that. Just plugging along.

Bigger throttle body - got told 1ZZ throttle body to air cleaner pipe wouldn't fit. Noted that both air cleaner pipes end up 70mm.
Take one 1ZZ throttle to air cleaner pipe - one saucepan hot water - dip too small end in hot water for awhile - force onto conical end of old hot dog muffler.

 
 After awhile remove, smear with rubber grease, force onto Corolla Sportivo Throttle body. Winner.
 

 
And from the Corrola 2ZZ throttle body, doesn't quite reach. To do this it would need extending slightly.
