Actually, this is a great time to resurrect this thread and ask the guys who have been pushing it for several years how they are doing and any probs they have had.

300+ HP for 3+ years guys- well?

Hey a quick FYI: PSI on 1 turbo will not make the same power at the same PSI level of another turbo. I am currently running 10 PSI and I would guess I am 280-300whp. I have had it up to 13psi for a day and it lived. Tuned on 94 pump

I wouldn't put anymore than 300 on the motor. And thats only getting into your turbo every once in a while. . I think I'd feel pretty safe at 275 which is what I'd like to have

I'm running near 300kW on stock motor (2015) and stock transmission. Still using the stock 215/45/17 tyres so they are the first thing to give out. And run varied boost from 14.5 to 18 PSI.

All depends on driving habbits etc etc. I don't boost past 4th gear. Mayyyybe 5th if high RPM and speed. Turbo comes in nice and slow to maintain rods etc.

Turbo/boost/torque coming in slower I get.
Not using power in 4th or higher makes no sense to me at all...

You rev the engine to say 6k with 14psi in 3rd, but won’t do that in 4th... why?

"To receive 350+ horsepower, you need the new fuel pump, fuel injectors, pulley and water/methanol injection. Don’t forget about transmission cooler and aftermarket radiator.
Instead of supercharger kit, you can install turbo kit on the basis of Garrett GTX3076R. Such kit is possible to install on stock internals and to receive 400 ++ WHP, and even up to 500 WHP (sport fuel).
FA20 stock internals keep more than 500 WHP, and if you use sports fuel and adjust ECU correctly, than over 600 horsepower."

What!

Do they mention expected life of 400-500-600hp FA20 with stock internals?

It said you can keep them not that they would last.
