Did anyone run coolant to wastegate on the SS set up ? or did everyone run the wastegate DRY?

 

Is there a thread on where to hook oil line to the head on an Evo IX?

 

You are referring to the oil feed line FP provides with the turbo, correct?

Since all the "new" turbos are ball bearing the oil feed line goes to the same spot on the head as the stock line did. To the left of the front cam angle sensor...

On the Journal bearing turbos the oil feed line came over the oil filter housing...

 

I have my wife's gate and a friend's running coolant.

 

Thought it was the opposite way around?

 

Nope, ball bearing turbos, oil feed line off the head.

Journal bearing turbos, oil feed line off the oil filter housing, for stock frame turbos at least. And make sure you pick the correct port on the filter housing, pretty sure (1) port is unfiltered oil & (1) is filtered oil.

 

Why would you run coolant lines to the wastegate? Unless you are doing constant hard driving like a 24 hr LeMans it's pointless. The every day driver and the weekend warrior don't need that.

Just a reinvention of the wheel. "Hey you have our old design wastegate and it works great for you?" "Well checkout our new designed wastegate, it does the exact samething but has coolant jackets now!" "You know you want/need it."

 

guess you never seen turbo setups under full boost. they all glow red hot under boost. doesnt take 24 hr race. it happens in just a few seconds.

 

When I bought my DBB FP Red last year FP were telling us to change the supply from the head to the oil filter housing, even had instructions on their website etc.

Should I change my set up now??

 

Is it a Mitsu center cartridge or the new FP center cartridge?

 

I have been building turbocharged imports since 1999 so yes, yes I have. Thermal coating of the manifolds, exhaust housing(s) of the turbo, running heat shields if possible, and thermal wrap will help keep the heat in.

Coolant circulating through the top hat of a wastegate won't make much of a difference. Never caused an issue before on any car I know of before they came out with this new design.

 

Hey has ANYONE ELSE tuned with a zero? Still waiting on results.

 

The new wastegate has a much smaller head than the old One. Smaller means less thermal mass so damage can happen easier but with cooling it can equal or surpass the larger wastegate. That's the point.

 

I have run turbos for years with out water cooling. to simplify service. does that mean its a good idea and not needed? heck no. water circulation keeps the parts at lower temps. the parts will give longer service life hands down.

 

It's the stock back housing. I bought it in December 2013.
