You'd think it would be fine at a high boost level like 30psi...its at the lower settings that it will struggle with boost control, like 7psi etc 30psi is a lot of boost man! Most people ive seen running these 35/40s are usually running around 16-22psi.

Just got the e-mail from him.. But yeah they are not an off the self item. Sorry for the confussion...

ah no worries great prices guys Thanks Tarek RACESPEC

I was just looking at HORSEPOWERINABOX and they do the T04Zs internally gated aswell as an option, the T04zs can also have a T3 style ex hsng apparently. Cheers for clarifying JNRGMH and agree with RACESPEC, nice prices.

internal gate will struggle to hold 30psi consistant, thats why u go to external to control boost better, boost spike or bleeding off boost can affect a car badly

What would a good turbo be to run 18-20 PSI all day everyday, ball bearing watercooled? going onto an R34 Neo RB25det? i want something that will spool-up reasonably quick.... around 1850ish

do you have any more of these turbos??? $1799 WITH INTERNAL GATE AND ACTUATOR
