On3 twin turbo install, some thoughts, and PICS.

[five.slow]

spring in the wastegate is not stiff enough. Can make tuning it a challenge. My tuner told me he prefers it closed at idle so I installed a stiffer spring.

Chris is tuning my car too. What spring did you go with? I'm assuming Tial springs will work right?

i had to change them and put the black hard ones you get in the box they made 9 psi on my car and they are hard to install
and the preinstalled ones are limited to 5 psi we did the measurement on the dayno

since yesterday i got a big knock every time just after the car starting then nothing and that cames from the Blow Off Valve on the inter-collar is it normal?

Tial WG's fit fine with my kit. I had to use the On3 clamps b/c the Tial ones didn't clamp tight enough.

Does anyone have pictures of how you hook up the turbo oil feed lines to the engine? My assembly "guide" says to refer to the pictures, but there are no pictures of it provided..

/\Thanks. I did figure it out already by trial and error. Would have been much quicker if I had a picture like this from the start..

Yesh... I meant BOV. A Tial BOV spring for 18-20" vacuum should work.

should not have cats at all on a turbocharged car.. the a/f ratio you will be running under boost will clog them up rather fast, then you will end up probably with a blown motor..

could you tel me what do you think of this converter http://www.americanmuscle.com/pypes-metallic-catalytic-converter-1114.html?source=igodigital

thx

Anyone notice their bov being open at idle? I know it doesn't matter because it's before the maf. I was hunting down a weird clank sound after start up and it's the bov snapping open about 15sec after I start the car. It works fine so far (haven't been into boost yet and it closes when the car is off) but the clank is annoying.

yes me since yesterday i got a big knock every time just after the car starting then nothing and that comes from the Blow Off Valve on the inter-collar is it normal?

 

[five.slow]

Donno if it's normal or not but ehh I don't care lol.

 

[MRSUPRA]

This is confusing.
So are the springs in the waste gates ok?
Is the spring in the BOV ok?

 

[five.slow]

Waste gates are fine. It's the bov spring that is weak, leaving the bov open at idle.

Mine has always been that way. Doesn't really matter as the maf is after the IC and the cold side piping doesn't see vacuum. My concern was rain or bugs getting in there on decel but it's never been an issue.

 

[five.slow]

Don't drive in the rain but if I ever do..... Got a spring on the way.

 

[MRSUPRA]

Good info..

hi
anybody had to deal with this code P0003 !

 

[helloWorld]

Question for the turbo guys. Do you have to let your car idle for a little bit (to let the oil cool down) before you shut it off after you drive it for a little while?

 

[five.slow]

Not if its normal driving. It's a bad idea to right after a wot pull.
