helloooo,

here is another debatable topic and a question thats has more than likely been asked before, I have a 1993 S1 R33 GTS that i have fitted the stock turbo kit from the GTS-T, the car has been fine for the last 6 months no issues, But now i wanna up the boost from the stock 5psi to around 10psi nothing crazy. My question is, the stock system runs a BOV and a internal waste together, now i have only been running the internal waste gate but i have just ordered a Greddy BOV and want to know if i can just run the BOV and not the waste gate (still leaving the actuator on there waste gate just not running the vacuum hose to it). going off what i understand it should be fine but is there anything im missing ????

BOV are used so when you change gear you dont back up your turbo and essentially keep it spooled when shifing, so why run a internal gate as well or is the gate just a fail safe so if the bov dosnt work you wont over boost your car?

Please, please, please, follow the advice about googling how/why a wastegate does what it does.

BOV and wastegate bear no relationship to each other except that you will find them both on a turbo car.

spend money on a proper diff...

Then again, 10 years ago I would have invested in a BOV (I actually did on my 1st car) - dumbest thing I ever did...

Don't talk sense. No one will listen with the BOV debate.

1. Learn how to construct sentences properly. It will help you in life.

2. You don't have basic understanding of how a turbocharged engine's components work together. This means you'll have to research them yourself in your time. No one here will school you in that, so have fun Googling.

3. Sell your after market blow-off valve and spend the money elsewhere (e.g. better tyres).

4. Look in the DIY section for grounding the standard boost solenoid.

OR, ignore everything I said and do whatever you want, because it's your money and your car.
