I recently bought a 3000GT VR4 tuesday, and unfortunetly have had some problems with it already, it has just over 116,300 miles and i just had a hub most likely go in my transmission i lost 1st and 2nd gear. It will go into gear when the car is running without the clutch so i figure its most likely 1st and 2nd gear hub or a fork. I had a problem previous to that im not sure of. When accelerating in 3rd-6th gear when ever the turbos put in 14 of boost there is a very violent shimmy throughout the whole car. But its only when you accelerate enough for the turbos to kick in high amount of boost, im left confused why this happens any ideas?

could be the prop shaft rubber carriers distorting under heavy boost!

Sounds like you may have spark blow out. Check the spark plugs and make sure you don't have crappy Bosch Platinums in there. They should be NGK or Denso's. If they look worn out or fouled out, get them replaced. If you are truely boosting 14 psi (via aftermarket gauge, not via crappy stock gauge) you should have the plugs gapped to .032"

As for 1st and 2nd gear being gone. Are you saying you can not shift into 1st or 2nd with the car running? If not, does it make a grinding noise or does it just block you out?

No while the car is running it will still go into 1st and 2nd gear without using the clutch and will not grind or anything there is no movement when you put it into 1st or 2nd, i was told it was most likely the hub that is stripped inside the transmission or wrecked fork.

Sounds like a broken shift fork to me. I believe you can get replacements at supercarengineering.com
I believe they make a billet set of forks. Kinda pricey, but if you are going to be racing the car a lot you might want to make the investment.

Maybe its not 14psi of boost then its just stock gauge, i checked the pluges and they are NGK, what should be the gap in them? But the shimmy is confusing because when ever you accelerate the car starts shimmying but its only when the turbos are putting out lots of boost.

Buy an autometer boost gauge to find out what boost you are really running. If you are running anything higher then stock you should gap the plugs down to .032"
If you are running stock boost .038" is what the factory calls for. It doesn't hurt to gap them down to be safe, but watch how much boost you are running. Too much and you will cause engine damage. Try replacing the plugs with some new ones at the same time. Also, get a pressure tester to check for leaks in your IC piping.
