What is needed for an external wastegate

[R33_KRAZY]

as the title says...i have a stock turbo on my 33 gts-t at the moment....what changes do i need 2 do to change it to an external wastegate setup..?? if i already have a turbo that needs an external setup..?? thank you in advance

Shitloads of stuff, speak to your local tuner.

You'll need ext wastegate, different manifold. You'll definetly need ecu, fuel pump and most likely better clutch, bigger intercooler, z32 air flow meter or equiv.

Thats of course assuming the turbo is bigger (being ext gate is probably is) and you plan to run a crapload more air flow then your current stock turbo. ie you wont be running 7psi on the ext gate turbo im assuming. its not the boost thats the problem its the airflow generated by runing the amonut of boost. of course if you want to run just 7psi and have an external gate setup then you should only need ext gate and manifold, ask a tuner

weld an adaptor pipe onto the existing manifold. it works fine

[R33_KRAZY]

i was running my stock turbo at 10 PSI.....how does this adapter idea work..? wat do you do...an im gettin a better fuel pump an cooler...

[R33_KRAZY]

so how much will this cost me 2 modify my manifold...??

bump....

if you have a bigger turbo that needs an ext gate, then you have to buy a new manifold. and manifolds cost heaps!

dont have to buy a new manifold, can modify standard manifold to suit. The ideal way is with a custom manifold but only if you have the money to spend.

thanx ofensv,

but what would this cost me to get done..?? thanx

[Merli]

Wait... Are you thinking of using an external wastegate with your standard turbo?? :confused:

[R33_KRAZY]

no im considering getting a new garrett turbo that needs an external gate an just want 2 know wat it is going 2 cost me 2 modify my manifold 2 suit the external gate...??

bump....

[OFENSV]

nothing if you do it yourself or know someone who can weld

nothing if you do it yourself or know someone who can weld

Since he doesent know what an external gate is to begin with i highly doubt he will have the knowledge to do a new turbo setup himself.

Unless you are planning on going all out with new injectors/fuel pump/afm/clutch/ecu etc etc i wouldnt bother as the turbo you are getting will be somewhere in the 500-600hp range coz its an external gate turbo. If the turbo was smaller then they wouldnt bother making it external gate

bump....

$500 or less.

i know of an S14 with the stock T28, that has had the manifold modified, and stock internal wastegate welded shut, and an external wastegate added. don't know if its worth the trouble or not but the car has run a 12.5.

R33_KRAZY first have to ask, why do you want to run an external wastegate? To hold boost better, to vent it to atmosphere or what?

[R33_KRAZY]

nah just because i plan to make my car FAST an POWERFULL....an they sound awsome an i got a really reallt cheap offer on a brand new garrett 500HP turbo..but it needs an external wastegate an i wanted 2 know what it would cost me all up so i could see if it was worth my while or not..?? an live n farm an know how 2 weld preety damn good...just need to know how i need 2 modify it..has anyone got any pictures of there setup...i intend to use a turbosmart pro-gate...so if any1 can give me a diagram or plans or just picstures on what 2 do then it would be much appreciated...thanx

[INASNT]

To actuall make the 500hp work like its meant to, you are gonna need around 15k for all the other parts if ur car is stock.

[R33_KRAZY]

ohh well that suks then....dammit....well how bout i just make it sound good an tough....

nah i intend 2 get this thing going hard..so i dont wanna waste money so this is y i want 2 get the right turbo setup from the start....but 4 interest sake how much would it cost 4 a custom manifold to suit this external wastegate setup..?? any help much appreciated

WATS WITH ALL THESE PEOPLE THAT CANT WRITE PROPER FRICKEN ENGLISH.

And wats with all these 17 y.o's that supposedly own hi po cars. My advice, go to performance forums or Hot 4's forum!
