Lemme see if I can scoop some pics for ya.

Driveline seems to be holding impressively well.

Clutch upgrade is a must. This is an ACT full faced disc. Handles quite well and is not overly aggressive on the left leg.

Stock bottom ends hold well on these 2AZFE’s so long as the tuning is not too aggressive. The conservative tunes like in the 11.0-11.5:1 seem to hold very well for quite sometime and abuse. Longest boosted time frame I have on one of these cars is 1 year and 5 months daily driven and weekend tracked 2-3 times a month.

The bottom ends should be considered to be set in forged internals if your goals are 350+. 300-350 seems to be the danger zone for things breaking (especially rings).

The cars drive pretty much stock, with a little bit of compressor surge when people elect the Stage 5 turbine wheel on idle. The 550cc actually idle pretty damn good on this set-up for sure. I was impressed the 1st time we did it. The secret to good idles and response is the VAC lines and the BOV used. We tried a few different ways, but this configuration is the most favorable.
