I have a SOHC Turbo setup. Done properly (way too much money) to accomodate high boost.

w/8 psi, 135 WHP(on dyno)
I have added a boost controller & plan on re-tuning the E-Manage soon. I currently run @ 10-11 psi w/no issues. Hoping to get up to >15 psi when it gets back on the Dyno. This is my daily driver, so I'm in no rush to attain light speed.

Although better than a stock DOHC setup, the cost was too much when compared to a B16 swap.

I have to say though, when someone w/a coffee can runs up my backside on the highway & I downshift. It's priceless when they take the very next exit.

Just realize that a proper Turbo setup costs alot of time & money.
