Hey mate, if your still having troubles with the vacuum lines I can give you a hand, pretty sure it runs a very similar (if not same) solenoid to mine.
There's a AE86 getting around with a RB25DET inside, made over 400hp atw and has run 10's on slicks, it's currently getting rebuilt with forgies etc....
If you want something other than what you asked for, go to Hardcore
Not only me, but quite a few mates have been stuffed around by them (blowing up turbo's due to wrong size oil line's, almost blowing up another mates R32), never going back.
