i've searched yes, my question what r some pros and cons of both? and rite now my turbo has an
internal gate set at 8psi, should i keep it that way or run an external w/a boost controller?

boostedEF91

External is for higher Hp/boost applications.. They allow you do turn the boost up alot higher than a internal and hold boost better, rather than fluctuating.. Also alot of the larger turbo's are not meant for a internal wastegate.. you can keep the internal if you dont plan on running going crazy .

Thanks, and yes the most i plan on ever runnin is 10-12psi, which this turbo runs on the talons via
the ecu anyhow, thanks again!

External wastegates are the way to go.

Better boost control, Decreased spool times, sound cooler...

What manifold are you using?

mikej94civex

it's an hf manifold, i kno they don't have a wg flange but i've seen ppl do it before..i'm just
gonna run the stock t25 internal wg at the 8psi it's set to, good idea?

not to thread jack, but to add to this topic, it is possible to turn any internally gated turbo into an externally gated turbo right? whats involved?

i went from internal wg to external with my greddy 18g on my stock b16 and went from 295hp to 350 just by doing that and going from the crappy log manifold to ramhorn,...all it involves really is to spot weld the internal flapper shut and get a manifold with external wg, oh and also take the internal wg canister and arm off the turbo too since you wont need it anymore...or not to thread jack also you guys can just buy my greddy 18g im selling now thats already all done with the downpipe and everything for external wg from me lol

Internal gates work ok for some applications. External works great for all applications.
