420A 4G63 turbo on a 420A?

[BCESI]

with no wastegate there won't be anything to control the boost. Whether it's an internal wastegate (acctually attatched to the turbo) or an external (not attatched, duh) all turbo setups need a wastegate unless you want to start blowing stuff up

As intriguing as blowing stuff up sounds...i think i'll pass so 8 psi is safe? or is that pushing it on stock 420A internals? thanks for all ur input

8 psi is a general figure thrown out there by Hahn and Howell---it is possible to run 8 psi, but buy a boost controller and work up to 8psi, each motor is different. I would not exceed 8psi.
