JE pistons are good too but aren't as metalurgically advanced so you'll have some piston slap when engine is cold. Not too dangerous but annoying.

As far as I remember, 993 engines with "dished" heads were produced for a year or too, and pistons were the same but jugs were shorter and heads were deeper.

A set of used re-ringed 993tt is probably the cheapest and best ticket here. They are made of tweaked alloy and will be quiet at startup. They are also tough as nails. Only problem with them is that they are somewhat don't rev past 7000RPM (In turbocharged engine, this is usually not the problem as they tend to produce max power fairly low unless tuned to max).

Hey goran,

So did you ever get your 911 running? Whats your website again?

What do you guys think of running a stock 993 3.6 with low boost? Theres a link to another site of a 993 with single turbo running a stock motor with low boost making 400Hp and it has been holdong up fine for almost 2 years .

What do you think
