Upgrading BOV on APS Kit: Suggestions OK, the APS Kit has two BOVs and they are kinda cheesy. I am sure they are OK and functional, but not optimal.
The kit came with very nice TIAL waste gates, but cheese plastic blow off valves. Has someone tried to upgrade them?
What is a good replacement part? Also, I plan on venting to the atmosphere rather than the recirculation set up in the APS kit.

As said the turbosmart supersonic kompact are direct fit. I posted a pic in another thread. I simply put plugs on the inlet bought at home depot and was running the aps ones non recirced. They were a bit louder but not loud enough for me.
The adjustments on top are explained when you get the blow offs. They just keep the car from stalling or something if they are set wrong.Sound simple to set. Access to the aps blow offs is easy enough and you don't have to mod anything to use these turbosmarts. Simply clamp them in place of the plastic bosch ones that come with aps. Their only downside is they are pretty pricey and you of course need two.

I installed Turbosmart Megasonics on my kit. Basically just welded the bigger flange over the smaller existing ones and then capped off the inlet side with some rubber chair tips. Test fitted the bumper yesterday and it looks like their is just enough clearance.

Not sure yet. I just finished the install, but my tuner is booked until march 18th so I have awhile till I find out how it really sounds. Started the car today on the stock injectors to hear the cam and make sure everything checked out. I will definately post up a vid when I get her running full tilt.
I have a Megasonic and it is damned LOUD... Search the FI forum for a thread using the keyword Megasoic, and my thread with vid's should pop up.
The adjustment on top is to reach the adequate spring pressure, with no tools needed twisting the case by hand... Keep it as soft (counter clockwise) as possible making sure the piston in the valve stays closed at engine idle... Once you figure out at what point that is, give it a little twist clockwise (harder) and you're good to go... No springs to swap the like Tial BOV's, and they will hold boost AT ANY LEVEL, especially the relatively low boost LS1's use (10-25 psi average). Very high quality stuff, well worth the price.
I put the Turbosmart Megasonics on my car they sound sweet and loud. You cant go wrong with them, they fit perfect in the bumper.
Oh yeah I have been running 17 PSI for the past two weeks Dyno day is tomorrow, Im hoping to get my bigger springs in today to turn it up to 20 PSI those 20g mits never stopped pulling on the street at 17# i am sure they will go to 20#

OK someone running bigger boost on a 402. What are full engine specs. Are you auto or m6?
Have you stented the inlet tubes or got the upgraded ones? Is this a dynojet you are going to? So you have stock springs in the gates.I was thinking some problems guys had with holding the boost past 15 or so is likely do to the smaller springs. I would think a 10psi to 15psi base spring would be about right.I like the idea of the lowest spring possible that would work and still alow the target max boost so can ramp up the boost on my eboost2.
Of course you can 't set it to lower than the gate springs.
Be handy if some guys runs some backpressure tests on these standard turbos on 402s and 408s.
So did you weld on the megasonics? Sure my bolt on supersonics will be fine for me. Another month or so to wait to drive my car. Only got to drive it a few weeks before had to put it away last year after getting it running near end of fall and winter here is NOT big hp friendly. Lucky still have the car after a few close calls on cold streets.
What are you running for tires at 17psi? How are they hooking up for you?
Going to think et street radials or m and h street radials. But hearing conflicting info on the nitto drag radials. My current nittos 275/17 are useless but they are also pretty much worn out.
Anyway give us some more details on your car, problems ,fixes ,etc.
