what is the best size of wastegate and the spring for t70, stock ports for run 15-18psi..?

 

HKS 60mm

 

and the spring? for lbs?

 

10lb spring will be fine for 15-20 psi.

 

I don't see the need for such a big wastegate while running the turbo in that range of boost. Maybe if you were trying to limit boost to 10psi or lower (with that turbo) running up to 8k+ rpms.

 

just get a hks 40mm standard one. its awesome and will be perfect

 

You're right, he doesn't need a 60mm. I was just plugging what wastegate I have

A 40mm would be fine for what he has.

 

and the springs? 10psi spring?

 

yep

 

I have an HKS 60mm II wastegate. The build quality of the 44MM TiAL I had on my 2 rotor was much better. With a GT35R compressor there was no boost creep at redline at 10-11psi.

 

the hks wastegate on ebay are good? where i can get one hks?

 

Some of the eBay ones are not made by HKS. They are knock-offs.

I have a psr 45mm wastegate..i dont know if it is anygood since i havent got my car running since i started the conversion.



oh yeah 10 psi spring.

 

I use a 56mm greddy type-c wastegate, no probs so far. I have a brand new Greddy 46mm Type R wastegate for sale. If interested send me a PM..

 

HKS GT2 60mm WG

I have had every type of Tial and they dont compare, all other brands are secondary choices realy.

GT2 = easy WG spring changes, very very configurable (5psi to 29+psi) full spring kit and all tools needed when you buy it, the way its made and the finish is first class, best on market. Great product.

 

Go with a 48mm Turbosmart Progate. Comes with springs, flanges..etc..etc.

 

HKS GT 60mm gate here, no issues

 

ok, thanks
