SR20 boost question

[enthennd]

Hello all. I got a sr20 with a t25, fmic/intake/open downpipe is all its got right now. It was at stock boost (7 psi) til I took the exhaust off and it hits about 8.5 ish now.

But I was wondering what I need to up the boost more? Would just a boost controller and walbro fuel pump be good?

And how much boost can I go to? I've heard 12 is safe, but I wanna know for sure! Thanks ahead of time!

yes 12psi is fine and i hope you arent still on the stock fuel pump is so dont even touch the boost!

get the hks acuator it go for 14 lbs safe but it well take a toll on your turbo.

Yep upgraded fp and boost controller and 14-15 psi is safe.

Awesome! Thanks, what kinda whp would I be around with 14 psi? Or 1/4, trap speed times could it pull off?

Trap will probably be between 100-109 mph depending on your 60 ft.

As other mentioned I would make sure the following

- Walbro or Tomei, Denso high flow fuel pump of at least 255 lt per hour installed
- Use HKS or adjustable wastegate arm WG actuator upgrade to raise boost
- Don't push more than 12-13 psi, there is no point on the t25. Efficiency is gone after about 12-13.5 psi. The HKS or adjustable WG arm will get you to the perfect boost level without need for an external electronic boost controller and will work better and be more smooth
