Greddy TD06-20G. (Wastgate Broke!) More rant.

[Red-KAT]

Yeah so anyways... After 2.5 Hrs taking my turbo off to port it... Before I took it in to get taken apart I looked inside to see how hard it was going to be...

Well the 1st thing I notice is the waste-gate hole is hidden by a nice weld on the outside of the turbo... and then the hole is only 20mm big... (sucks)... But... Then I notice I can see right in the hole? WTF? Where the hell is the flapper door? Ohh missing!!! (Well no wonder boost was a little slow lately)

Yeah so I took it to the shop anyways to see what they said about it... They told me the same thing I was thinking... This sucks for you.

So... I guess what has to happen is we are going to fill in the waste-gate hole with metal... And weld a tail (sp) 38mm onto the manifold (I might route it to the down pipe) They said they have had good luck welding on cast iron so we will see... If it cracks I would like to get a new mani that would place the turbo in the same spot... Or just replace all this ****. (So much for the AEM next check)

was this turbo bought new? post pics.........

[Red-KAT]

Yeah the turbo is not even a year old. Good thing is all the seals are still great and it has almost no play in the shaft. I'll post pic's once I get home.

i hate having to spend money just to fix things instead of upgrading. i hope everything works out for you

[:: orion ::]

****...internal to external WG is an upgrade.

Less exhaust that has to be forced thorugh the turbine inlet = less restriction, more power!!!

External gate on the manifold is MUCH, MUCH better than internal gate IMO.

Get it done, come back with pics.

welding cast iron just like welding steel, but you have to use a torch to heat up the cast iron then weld on to steel or cast iron.

welding cast iron just like welding steel, but you have to use a torch to heat up the cast iron then weld on to steel or cast iron.

Depending on the thickness of the cast iron object, it should also be welded using a torch rather than arc welding or it's variants. Arc welding will heat the area local to the weld much too quickly, even if you preheat it as electric welders bring the metal local to the weld up to extremely high temps. it should also be cooled slowly in an oven like device. The temperature decrease over an alloted timeframe seems to be a gray area, as different welders seem to have differing opinions. But be very weary of anyone who says they will arc weld it, or anyone who doesn't include a preheat and a long cool-off.

I went tot he shop and took a look at their DSM they have modded out the ***... It was a steel flange tapped, bolted, and welded to the mani... Then the wastegate on that... I should have took my camera with me but... I did not.

So anyways here is my HUGE pics of the current stuff... No my car is not pretty to look at.

Go here for the ultra HUGE ones. http://nissaninfiniticlub.net/...t=500



Hope that worked.

what area of the manifold are you thinking about placing the wastegate? i am looking into the greddy kit now, seeing as i already have the e-01 and a wideband and was thinking about doing this as well. not right away but maybe a bit down the road once i get more money. keep me update so i can see how it goes.

[Red-KAT]

I'm not going to make the choice... I am going to have the shop look at it and make them decide the best flow spot. I dont want another issue.

I'll post pic's before I install it all again and with it on and then with it compleat. I hope this does not cost to much. :P

[:: orion ::]

IMO, straight off the collector (towards the shock tower) would be best, just like the RevHard.

Your Text » Ok... So I'm planning to finish off my exhaust the right way this time. Here is what I have ordered or arrived.

Catco 3" CAT (have and 2nd 02 bung will be welded on soon) black Exhaust wrap 2inch wide by 100feet. (I duno 100 feet sounded good) 50 feet of exhaust wrap fasteners... (overkill? most likely yes!) 4 cans of exhaust wrap sealer... (I may need more) Tial 38mm waste-gate with all flanges and .5bar sprint 7.25lbs for us lame folks.

I am also thinking of ordering a turbo blanket... Anyone know a good one?

And if you can think of anything more that I might need! tell me! I don't want to take this **** apart again for a while...

can we say tax return?

EDIT: Whats a good site for silicon intercooler connectors? some of mine are tore up.

Gte that heat resistant cloth crap from home depot. Works WONDERS

[95_240sx]

Have fun welding on cast iron, you have to stick weld it

Why dont you just fix the turbo? What shop do you goto? PM Me I am just in Portland so hit me up.

[Red-KAT]

I would rather change to the Tial 38mm wastegate then fix the turbo. (Already on order)

I went to the shop you are not fond of... on airport way (I'll give them a shot its not like any shop will do much on my car.)

I seem to be at a loss on how to PM...
