ok i've decided to boost my beater =P
got my hands on a 14b and was wondering how i get the boost down to 7-8psi...i believe stock talons run 10-11psi?
i guess i have to change the wastegate actuator...but where do i get an 7-8psi one? or is there a simpler solution?

 

ttt

 

boost controller???

 

So much much boost does a 14b pump out with stock wastegate???


Yager-

 

i have got 16psi out of mine on a LS.

 

anyone know for sure how to get the boost lower? i'm plannin on buying one myself soon. just waiting to find out how to lower the boost

 

someone told me that if you run the wastegate vacuum hose to the turbo it should hold 7-8psi...doesn't make much sense to me...but apparantly it works

 

You can add washer's between the bolts and the wastegate flange so it moves the actuator towards the valve.

This will lower the boost.

Just don't know how much until you try it out. Keep adding/taking out washers until you reach the desired boost level.

 

The only method I could think of would be to lengthen the actuator arm , causing it to open more, sooner. This however would also lead to slower boost spool, not to mention I really dislike fidling with the arm.

so does anyone know for sure? like a way that has actually been done and has been proven to work.

 

Oh yah and btw... what about welding the w/g flapper hole shut and going with an external wastegate?

 

why do you want to run lower boost? It's not a big turbo?

 

they just told you replace the actuatior or legthen the arm by washers or adjusting it.

sorry for the spelling. it is close to 5 pm and all i can think about is leaving work

 

because i have a d16 civic with stock internals... 10psi is kinda pushing it. It's my daily driver.

 

i am sorry but that was a stupid question

 

Replacing the actuator isn't an easy task... i called turbochargers.com, they said it would be a lot fabrication.

Adding washers sounds possible, but i want to make sure it's something that has been done already.

 

they must not know what they are talking about. what you need is just to replace the actuator, no welding no nothing!

this is what you need, i dont know what the specs are but all you have to do is change this out http://cgi.ebay.com/ebaymotors/ws/eb...879346&r=0&t=0

 

Yah I thought so too. But the guy said that not just any actuator would fit. Even in the bid you just showed me it says that he's not sure what turbo it would fit.

 

worst comes to worst you just weld a new bracket. very simple!! just make sure you buy one that has the right boost setting. i would find one that has the lowest setting possible. you can always raise it just not lower it.

 

yah i think that was what the guy was talking about. still hassle. grrr i hate turbos.

 

I just currently finished a diy turbo on my hb with a 14b..with the stock acuator it boost 6-7 psi....no problems

 

how'd u make it boost only 6-7psi?

 

if the 14b in stock form puts out 11psi, is that too much for an LS with stock internals?? i know it's pushing it but i hear about people boosting like 15 or 16psi on stock internals thanx to good tuning. i already have a 14b waiting to be installed and would like to know.

 

11psi from a 14b on an LS is NOT too much boost.... personally I do not think this is a good match for a LS as it will die off very quickly at high rpm.

 

I stick to my guns.... 10psi is not too much for a d16 with a 14b (with adequate fuel that is).
