Hello,

I come to a point that I need to order springs for my tial mv-s 38mm wastegate. How much psi can I put on my build d16z6 ycp vitara pistons 75,5mm , walbro, 750cc, t3/4e , eagle rods, bisimoto valve seals and springs and the rest is stock oem as for im tb. I want to push as hard as I can with this setup without breaking the engine. After some research I found answers varying from 16 psi to 30 psi. How much psi is "safe" and how much is really pushing it to the edge?

Back in the days people also searched first and used proper grammar and could form a coherent thought.

You are asking the wrong question. 10 psi on a t25 is different from 10 psi on a T4. Are you tuning this your self? If so ... there's way more to it than how much pressure you're going to let your turbo run and you should probably hit the books. I'm sure what you really want to know is what would be a safe power level.

What injectors are you running? What fuel pump? You can go as high as the most limiting factor of your build will let you.

Stock fuel system ... good luck getting over 150 whp. Stock exhaust ... that's a choke point. Stock clutch ... that'll slip fast.

If you aren't tuning it yourself your limiting factor is going to be your tuner and his comfort level/experience. Ask your tuner how high he's comfortable taking your set up. Or just hand it to him and find out how high it goes.

Did your wastegate not come with a spring? Just use the one that's in there and turn it up with a boost controller.

Apparently he searched enough to put Vitaras in the block.

There goes throttle response..

But im sure this has been said tens of thousands of times over all the honda based boards..
