Also can i run no wastegate until i sort out my external wastegate situation?

I wouldn't do this. The wastegate will stay open and your turbo will spin and spin. I'd assume you can hurt the turbo if you over spin it so I wouldn't do it. Someone correct me if I'm wrong though.

No your right i found out shortly after, question is how do i remount the wastegate going to have to figure that out

If i used this spacer do you think the turbo would hit the radiator? That would give me clearance for the WG

Actually if you have no wastegate it won't build boost at all. It won't hurt your turbo, but you'll be very slow.

I was hearing it would over spool and kill components

I've never heard of it. I could be wrong though.

It wont build boost, true, but it will continue to spin faster and faster trying to build boost until it over spins itself which burns up the bearings inside the turbo.

Below is a thread from a supra forum giving a general idea of over spinning a turbo because of a bad bov.

Good link,i tried and tried to mount the internal now im just saying F it amd buying a external
Oh and my water leak was a cracked waterpump im guessing it happenned when i was driving up on the toe truck -_-

I welded the WG flapper shut! Now what would be the best size EWG to use?
Has anyone else put one onto there stock manifold?
Should i go ahead and get a tublar?

Ive welded an external onto my stock manifold. I used a turbonetics deltagate 38mm works well controls boost well.

 

[Area6]

You always have the answers! Im not going to weld it i have a good idea!
Im looking for a 38mm 2 bolt wastegate right now

 

[foxracer52]

My question is why did you weld the flapper shut on the holset? Dont you have a Hy? with no divider in the middle? the only reason I've put an external on my car is cause of the hx's divided manifold design. So with an hy you shouldn't need an external, but i could be totally wrong.

 

[Area6]

Well your reasons are different than mine!
The internal wastegate is hitting the balance shaft area of the block, and external gives better boost control anyway! Id rather do it right than worry about boost creep and other issues

 

[foxracer52]

Ahh good point good point. But anyways there really isn't another way to putting an external on a stock manifold then to weld one, whether its a 2 bolt or v band style flange is up to you but I've had good luck with that size and welding on the stock manifold.

 

[Area6]

Did you weld it your self? How did you make the initial hole in the manifold drill?

 

[foxracer52]

I had a friend weld it with my mig welder with gas hook up, I use a Hobart 140, he's had more experience welding then I have so that's why he did it. As for the hole I used a hole saw drill thing

 

[Area6]

My exhaust man said he is going to mig weld it for me, that weld on the wastegate flapper was my first ever weld lol

You have any pics of your setup?

 

[foxracer52]

I can't post a picture from my phone and that's all I have cause my home internet went down

 

[Area6]

Im going to pm you
