How can you tell the wastegate spring pressure? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

*Jeff240sx* · 05-28-2002, 12:21 AM

I dunno if I posted this, but if I did, then I lost it, and have to post again.
Anyway...
I bought a tial 35mm wastegate via ebay.  From some seller who is the owner of tuneablecompacts, and doesn't list wastegates on his site??  
Anyway, I mentioned that I needed a .3bar spring at most.  I waited a week, didn't get it, waited another week and he said tial was finishing the wastegates, and they would drop ship the gate.  And 2 days later, the gate was at my door.
And on the box, there is no sticker from tuneablecompacts, just tial stickers all over.  
And a sticker with a serial number written by hand, and a line: "Spring: .45 bar" written in hand, in pen.  But then in a different pen, .45 was scribbled out, and a .30 was scribbled over it.  And even the packing invoice says "Wastegate 35mm .3bar (4.35 psi)" on it.  And the guy that I bought it from said it would have a .45 bar spring in it.
I just don't know who to believe.  And if it is .3 bar, why is it so hard to push.
I intend on installing my turbo in 2 weeks, and I just don't want a 6.5 psi spring on my stock fueled car and have to drive around at 2500 rpms for 2 weeks till another paycheck.
So... someone give me some advice.

Well, I don't know much about Tial wastegates, but I know that HKS uses a coloring system for their wastegate springs.  Dependant upon what color you have designates the spring pressure.  If you can get ahold of Tial, I would give them a call.

i could be wrong but if u call tial they can tell you that they only sell a 6.5psi spring and a 12psi spring. but i could be wrong. call them! i never heard of tial selling a 4.3psi spring

*Jeff240sx* · 05-30-2002, 03:09 PM

Well... I called tial and they said that they sell all pressures of springs, and .3 bar is the lowest!  Then they said that the spring in mine was a .3 bar.... so I am really happy.
And the only reason I'm posting this... is so others know that tial sells low pressure springs!  Saved me $40 over another spring, too.

hey jeff, i keep on forgetting to ask. WHY do u want such a low pressure spring.? so u can run 4psi? thats nothin.

Hey man... I'll build the motor up... just loan me the $2500 for internals and fuel.  LOL!  No.  I have to run 4 psi right now cuz my car is stock.  And my car is broken, so priorities first.  I got hit by a car in a parking lot, a hit-and-run, and my insurance won't touch it.  Thats $3000 I have to save and spend before college starts.  So I figured if I got the turbo on my car, did a manual swap, and fixed the cosmetic damage before I go to school, I'd have a fast(er) manual, nice looking car to show up in Tampa with.  And build the motor as I get the $$$.

correct me if i'm wrong, but I thought a stock KA could handle about 6-7 psi on stock fuel systems?

*Jeff240sx* · 06-01-2002, 11:36 AM

No.  You're wrong.  (Sorry, you said correct you)
Sure, it can be done, but I am talking about everyday dependability here.  270cc injectors, threoretically, according to somebody's math will max at 5.xpsi.  I don't even want to go there.
