when asked if you had a stock tii, you said no, you're getting a bigger one. I take it that by that, you mean a bigger turbo... so.... you'll need everything.... Injectors, pump, wastegate (expanded or new), bov, fuel controller, boost controller, guages out the yin-yang, full exhaust, and tuning. If you're gonna do apex seals too - then ****, I hope you won the lottery.

By the way, to answer your question, stock apex seals can handle 20 lbs if you do the set up right. increasing the size of them is for big boost pressures, like with fd's running t78's and what not.

the apex seals are the first, and weakest point in the internals of the engine. stock seals are extremely good at doing what they do. Most people think you need 3mm seals, but thats not really a necessity. if your opening up the engine and have the money to mill the rotors, you mihgt as well, but upgrade to FD seals at the same time. Make sure you have a good FMIC and have plenty of fuel to boot.
