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.
without the headers and the turbo, it is close to 400lbs.
7 psi is safe to boost on a stock d-series motor
If it hasn't got a turbo there's no place for it to get boost from.
AnswerIt can handle roughly 26psi. No more. I personally wouldn't go over 20 for a DD, 25 for track.
It can be done. But for a price. The 420A motor (GS and GS motor) have the transmission sitting on the right side. (If your looking at the front of the car) And the 4G63 (GS-T and GSX motor) Have the transmission sitting to the left side. So just a straight motor swap is NOT possible. But I suppose if you got a GS-T motor and transmission then you can remount the motor and transmission mounts, but you would probably have to relocate everything, such as the ecu and battery and whatnot. So to answer the question, technically, it is possible. But illogical. You would be much better off just selling the GS and getting a GS-T, or just put a turbo on the GS.
225 horsepower
you might be running too much boost off of your turbo especially if youre running a stock turbo
Only about 7 or 8psi safely on a stock motor anymore than that your asking for another motor. Experienced this with 12psi was fun lol and I was impressed with how much it held up to.
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
Putting too much motor oil into your motor can be as destructive as to little oil. You will need to drain the excess oil from the oil pan.
6 pounds of boost is the safest without engine damage. the compression ratio of a type-s motor is 11:1.0 this is really high, and to add more pressure on the motor will simply cause engine damage. most turbo cars the come stock with turbo have a ratio of 9:1.0 or 9:5.0 having a boost controller is very important when adding a turbo or supercharger. at 6lbs of boost, you will have 50-60 hp more. and for the type-s its pretty good. anymore you will need motor work.
They actually made several different versions of that motor...
