May seem a stupid question, I havent had a turbo before.
Not about my datsun, it hasnt been started in months
How do you increase the boost on a turbo,
just a couple of psi over stock

You could shorten your wastegate actuator rod on an integral gate,
Or you could use bleed valve or increase the sternal gates spring pressure

so theres no simple adjustment then?

crimp the hose that runs to the wastegate or take it off and il run max boost done this on me exa used to run 8 pound everyday then when i took the hose off the gt28 would spit out round 17pound

I was after a small increase to start off!

Get an airtight vessel, and run a hose from the wastegate actuator line to it. The turbo will have to fill the vessel with pressure before the wastegate can open. This will cause a nice boost increase mid range, but the boost will flatten off in the higher revs.

or you could spend $40 and get a turbotech boost controller off ebay....

The method I described only increases boost lower in the rev range, when there is plenty of spare injector cycle available. Reduces the risk of lean out from injectors maxing out.

think i will go with tyries suggestion, more control I dont want to blow it up. thanks for other ideas.

I have one of these, was only used for a tune (1hour) then put back in the box. Is missing the silicone hose. Yours for $20 posted if you want it.
