It's pretty obvious you haven't done any research at all.

1. The turbo is a VG30ET, not a VG30DET.

2. The VG30ET has made over 400hp with basic mods. A junkyard VG30ET has actually made 800hp with just external parts like big turbo, new intake, exhaust, and a small shot of nitrous.

3. The cost of swapping in a VG30DETT will end up running you anywhere from $2,000 to $10,000. Since you're asking this question, you haven't actually sourced any parts or know what you're getting into. It will probably run YOU closer to the $10,000 mark.

4. The amount of money you would spend on doing a swap would better be spent building a more powerful SOHC VG motor.

is the motor running? compression good? if the mtoor requires work that has to be priority, and wile you have ti apart, metal HG's and ARP headstuds are money well spent!free flowing intake and exhaust, big turbo, big fuel injectors, FMIC and romulator or some other means of tuning for the larger injectors and turbo will get you 300-400 whp

also remember that a motor spwa is never as cheap as you think, once you buy an RB25 you's still have to modify the oil pan, pickuptube, crossmsmber etc, and still need to add intercooler piping etc

keep the VG30ET in it. I WANTED to do a motor swap in mine i just didn't have the time/money or skill. and judging by your post you don't have any knowledge of the car to begin with.
