bought another gsx need a little help

[RedDragonGSX97]

I recently purchased my 2nd gsx. Its a 96 auto. Got it for 1500 with a bad t-25 and some very minor collision damage. I have two questions that i have concerns about before i start driving it.


1.I know it has boost leaks. I have already replaced the turbo with a good used t-25 with no shaft play.When the turbo spools up it seems very quiet (unlike my other gsx which is loud) and it feels like it is straining to move. I expect this from a car that has sat for two years. Other than a boost leak test is there anything else I should check and what is the most common leak spots.

2. On the BCS there are two vacuum lines, one goes to the wastegate, and the other is suppose to go to the intake snorkel. The problem is that the intake snorkel does not have a third nipple for the vacuum line. Instead the line is capped off and thrown aside. Should I add a nipple to the intake or T it into another vacuum line? I don't think it is a good idea to leave it capped.

Thanks for all the help. I'm kind of new to DSM's and turbo cars in general so bear with me

1. Fix those boost leaks, that will cause a very serious problem with it's pick up. Also change the plugs if you haven't already. Most people now have found that NGK BR6ES plugs gapped at .028" are the best you can use on a stock platform. Make sure you order the BR6ES and not the BPR6ES (although they work great too) the BR have seemed to work better for most people (myself included). Don't worry when the people are the counter look at you funny for buying motorcycle plugs for a DSM, they generally don't understand. And make sure they are NGK's.

For the BCS, my advice- remove the vacuum lines from it and run one small line from the wastegate to the J-pipe boost source, eliminating the BCS completely. Then when you want to turn the boost up you'll T your MBC inline with that single line and not have to worry about hitting fuel cut or any of the other problems that the BCS causes.

Ok i have changed the oil,rotated the tires and cleaned the car up nice. I will change the plugs and all the timing components soon. I am gonna make me a cheap boost leak tester in the next week. Thank you man.
