Here is a time-lapse sequence of (crappy) phone pics of my build up prior to TX2K8. I've added a few descriptions along with the images.

I performed all the work except for building the shortblock; carchitect assembled the bottom end.

From beginning to end, the car was put together from 17 Feb to 23 March.

Enjoy!

Built motor: 8.5:1 Wiseco pistons 20 over and Eagle rods


L19 head studs. Also note the dull looking valve retainers, and compare those to the Crower retainers two pics down.


Head/block assembled. L19s torqued to 90 ft/lbs.


Crower springs and retainers. For reference, I found specs on Stock, Crower, Brian Crower, Manley, and Ferrera spring rates:

Stock: 185lbs/in (http://www.crower.com/cat/import/toy...lvetrain.shtml)

BC: 226lbs/in (http://www.briancrower.com/makes/toyota/2jzgte.shtml)
For some reason, PHR lists the same product with a spring rate of 260lbs/in (http://www.powerhouseracing.com/Temp...=10&SearchYN=N)

Crower: 237lbs/in (http://www.crower.com/cat/import/toy...lvetrain.shtml)

Manley: 245lbs/in (http://www.manleyperformance.com/pdf...Comp-51-76.pdf Page 67)

Ferrera 2jz-ge: 305lbs/in (http://www.ferrea.com/catalog/2004SP.pdf Page 86)
Ferrera 2jz-gte: 285lbs/in (http://www.ferrea.com/catalog/2004SP.pdf Page 86)

I selected Crower because their spring rate was agressive but nothing like Ferrera. Also, twice I lost keepers in the motor. One dropped down an oiling hole all the way to number two oil pan, and the other dropped into a cylinder. Fortunately, I was able to retrieve both!

First pass at assembling the long block. I'm running a Precision T74GTS turbo, .81 A/R.


Back to some head work - shimless buckets. I ordered these from Curt Aigner at Elmhurst Toyota. You have to measure the total thickness of all your buckets/shims and then find the closest shimless buckets with the equivalent thickness in increments of .05 mm. Total cost of all shimless buckets was about $378; that's pretty cheap insurance if you're planning on spinning the motor past 8k with an agressive cam.


They look like plug quarters when installed in the head


272s installed over shimless buckets. Fortunately, all my measurements were correct. I didn't have to reorder any additional buckets.


Next, it's on to installing the Tilton clutch with the 12lbs flywheel. I had the opportunity to do a thorough inspection, and I was amazed that the entire clutch pack (all 6 carbon disks and pressure plate) only wore 0.013" after 10k miles of use, many burn-outs, and a few passes down the drag strip. According to the instructions that come with the clutch, I don't have to swap in the next thicker pressure plate until the clutch pack wears 0.025", and the clutch comes with two additional pressure plates. So, it appears the Tilton will last quite a while if driven properly.


Getting closer... tranny bolted to longblock. Notice the downpipe diameter - as it turns out, a 3" dp/mp and the dual 2.25" exhaust is holding the motor back. That's my next project. I currently have a 4" dp/mp combination that I'm mocking up, and I'll probably go with dual, double offset, straight through, 3" Magnaflow mufflers.


Here's the motor/tranny installation. I'm finally getting pretty good at this; it only took about 45 minutes to get the motor on the mounts. Getting the whole assembly in is like working a jigsaw puzzle. There's only about 1/2" clearance side-to-side, and the motor clears the A/C condensor by about 1/2".




Here it is complete!


Again... sorry about the pics, but it was a short build. And I wasn't real steady with the phone.
