I purchased a tial wastegate (38mm) 2 months ago and all was fine. I ran 7 psi. Then i installed exhaust wrap, reinstalled my turbo manifold, and reinstalled the wastegate, and my wastegate now dosent seem to be opening. I was driving and accidentally went above 12psi. I checked all the lines, and i just dont know how it could have broken. All i can think of is when i installed the wrap, the wrap smoked like crazy, and maybe the heat busted the spring. PLease give me your input. Thanks

 

Did you use any leaded race gas? Have you checked your diaphragm? Are all of your vacuum lines intact?

 

what he said

 

I did not use race gas, i double checked my vacuum lines, and my diaphragm looks alright. I dont know what to do.

 

is it a real tial or a knock off one?

 

make sure you hooked up your vacuum line to the side of the wastegate and that it has a good source of vaccum like brake booster or something strong hope that helps out

 

i just went out to double check the settings, and everything, the only thing i think it could be is the boost controller. Do wastegates really break this easily, and what would cause the spring to bust/warp

 

Sorry, it is a real tial wastegate

 

take the boost controller out and just run straight vacuum to the wg that will tell you whether or not it is the boost controller or not

 

You can easily check it for smooth operation if you have a handheld vacuum pump.
If not any local mechanic should have one.

 

Use a vacuum pump and pump up the gate manually to check if it opens.

 

thanks for all your feedback

 

Ive seen this problem before...and it turned out to be the electronic boost controller....post i read a while back, his boost kept riseing when everything checked ok.

 

hey this is the guy that you met at pizza hut lol. Good to see you on this forum.

 

what knid of turbo is it? i hope its not a big crappy t3/t4 turbonetics crap . j/k its luc. if u said the guy at pizza hut could help ask him and then if it is still messed up then buy another. when i was lookin for ur fourm i saw a post that was titled rear located turbo kit or somethin like that it was crazy lookin. peace

 

yup thats me, if you want to get a hold of me here's my # 300-3277 ask for Henry.

 

Be sure you didn't swap your side and top fittings on your tial. I know on mine if they are hooked up backwards the BC won't control boost at all. HTH

 

Henry i am a friend of Shaz (the kid u met at pizza hut) do u know when the stl honda-tech meeting is?

shaz i burnt the crap out of my face at work sunday morning. thats why i havent been at school the past 2 days.


we set the BC up right. i think that it is something internal but not the spring. this is the second wastegate we have gone through on the car.

 

how long are your vac lines? That could possibly cause an issue

 

did u reverse your wastgate? (the valve is NOT pointing down towards the manifold)

 

ok never mind on the h-t meeting i found it. i was wondering if trial H-T members can show up(even though i have a celica i wish i had a honda).

?

 

i dont think the vac lines are the problem. we put the wastegate on right it only fits one way

 

did u change the spring in the wasdtegate? maybe you didnt put the wastgate together properly example pinched the diaphram

 

How long are they though. if the lines are too long that can cause a problem.
Also did you put the ring in the wastegate in when installing it?
