How do you turn up the boost with the SOHC Greddy kit using the Blue Box? The turbo is using an internal wastegate, so do you have to replace that with a external adjustable wastegate and different fuel management system?

Right now Im only running the 5.5psi, but I wanna turn it up to maybe around 8psi. Any help?

 

you need a boost controller, manual or electronic. that is it.

 

pinch a hose.

Nah don't do that you may not like the outcome...

I actually don't know?
bump for u

 

Shortening the wastegate actuator arm increases the tension on the diaphram's spring...thereby increasing boost.

 

u could mess around with the wastegate actuator arm but personally i would rather get a boost controller and do it from there

 

So installing a boost controller can still run a safe reliable 8psi daily? what about a separate fuel management system instead of the Blue Box, or would the Blue Box be safe up to 8psi?

I've searched, and some say to do a different fuel system while others say it is still safe at that low boost level.

What is a better overall Boost controller? I like the way A'pexi looks, but others say the Greddy is easier to use. Or would a manual be a better low cost alternative?

 

depends on the features you want with the boost controller. Gear dependent boost levels. or just simply 8psi daily. ofr 8psi with the blue blox IMO should be alright. I upgraded to Hondata because i plan to boost higher than 10psi.
