AnswerIt can handle roughly 26psi. No more. I personally wouldn't go over 20 for a DD, 25 for track.
about 60psi
The f22b1 is a great engine for boost it has a compression of 8.8:1 and can handle 12.1:1 so you boost about 11-12lbs. On the stock internals no problem.
Yes, it can only if you run more than the heads can handle. With the proper amount of boost she will purr like a kitten.
Stock turbo can run close to 14 PSI...but you can increase as much as your turbo can. The engine will not last as long with higher boost. Upgrading internals such as pistons, rods, crankshaft, camshaft, and valves can allow much higher boost.
8lbs max, anymore and you better cross your fingers.
There isn't really a set pressure it can handle, it all depends what is done to the motor. If it's completely stock, not more than 15 psi because the fuel system can't keep up with much more. Upgraded fuel system and turbo, you can do over 20. I have a 1990 tsi with fuel upgrades, bigger turbo etc, but stock internals and I'm pushing close to 23 psi.
You can put a supercharger on a stock engine it depends on how much boost you run wether your engine can handle it or not.
i wouldn't bother just get a turbo 4g63. the compression is higher on the non turbo 4g63. and the turbo 4g63 has oil squiters to cool the pistion and cylinders. you will spend as much money putting a turbo on your car as the difference would be selling your car and buying a 1g tsi awd
Are you talking about taking a 4g63 out and putting a 420a in? If so, i don't understand, why at all, you'd do that.
without the headers and the turbo, it is close to 400lbs.
yes. both engines are the 4g63. the turbo engines from the 1990-1994 is a 6 bolt 4g63 and the turbo engine from the 1995-1999 is a 7 bolt 4g63.
