Turbo from a RA engine

[dotterweich]

As for the differences between 1.9 NA and TD engines, the TD has 144mm rods and 26mm pins, where as the NA has 150mm rods and 24mm pins. I can't remember where I came across this info, but it was a while ago. The compression difference must be in the size of the flame path depression in the piston or the swirl chamber volume, unless the piston protrusion/ head gasket thickness relationship is different between the two engines, which is doubtful. Interesting though that the NA has a better rod ratio than the TD, albeit weaker pistons.

The td has shorter rods and longer pistons, giving the same block height. The rings are much lower down the pistons.

Just don't utube any helmet cam videos of you wailing on your latest mods while narrating, and nobody's the wiser, especially the new and improved world order nazis. Besides, where the hell is oregon anyway, the spice cabinet? I used to break the entire motor vehicle code out of Silverton, population 5001, never did figure out who the "1" was...

So on the topic of breaking engines with too much boost, what's the stock AAZ bottom end good for if no main studs and no girdle?
Can we twist up the wick to 30psi and never lift and NOT have main cap walk cook the bearings? Who's broken the stock main cap bolts at what boost under what driving conditions? What's the collective wisdom say about beating AAZ's to death?

Max boost depends on everything. 30psi could be translated anything between 100-250hp. 30psi is way too much with stock turbos, but not much with bigger. I've seen a few 200+hp aaz with stock bottom ends.
