Making Internal Wastegate Turbo External

[jnr32r]

Ive got a hks manifold with wastegate (not installed yet) but my 2535 uses an internal wategate. Is it possible to weld the internal wastegate and simply use the 40mm exernal wastegate?

I guess the benefits i would like to see is that the airflow from the wategate and turbo are separated although this can also be achieved by a a split dump pipe...

can anyone shed some light

Im thinking of doing the same wit hthe same turbo

I was going to get another dump pipe flage and weld flat flat on it. Then cut out a hole for the turbine exit (i think it's roughly 2inch) then step it out to 3inch.

So you werent going to weld the actuator "door"? just weld a solid flange on the tubos exhaust...

[Mr. Oizo]

you have to weld the hole where the wastegate flapper is

then make sure its smooth on the inside so it doesnt hinder flow

no you dont, just make sure it cant open, welding up the wastegate hole in the housing will just cause you dramas such as cracks, and it will take 100 hours to diegrind the weld down so it is smooth

of course you dont have to

but if you dont do it properly its just hindering flow

Like this.

I dont want to tack the flapper so if i sell the turbo. Instead i will make a solid rod(take off the actuator) so it is locked and wont open and if it do'es who cares as the dump pipe will be sectioned off

[Adriano]

yep, thats exactly how id do it

[jnr32r]

thats a good idea... but do they sell a solid plate flange like that?

[Dynamix]

I'm sure someone could knock up a plate like that for bugger all, hell even i could do it with the tools at home..

hey pablo go to gcg in condell park

check the plate out on there website www.gcg.com.au

Are you going to make the new exhaust urself? Or will you get a shop to fabricate something up for you?

I heard Mr C Engineering in your area is pretty good.

Keen to see how you go with this. Good luck!
