I currently have a Mitsubishi 14G, but I'm maxing it out at 10 psi in 2nd & 3rd, boost levels off to 6 psi B4 I hit 8K rpm's

My current setup:
D16Z6
14G w/restrictive downpipe 1.5 to 2 inches. (to preserve A/C)
2.5 " piping after downpipe,2X resonator to flow through exhaust. No Cat
Drag exhaust manifold
Built up block w/9.0 compression
5 speed with heavy clutch
440 injectors
B&M Fuel Regulator
E-Manage with secondary MAP sensor
XL 2 stage boost Controller
Spearco FMIC
Fluidyne radiator
Nology Hotwires

Next set of upgrades:
AEM fuel regulator
255 in tank pump
FAL fan for Fluidyne
Custom tubular exhaust manifold, w/offset to accomodate
a. 2.5" downpipe
b. MayB larger turbo
c. A/C
Turbo ?????

I'm the original owner, so theDelSlow has sentimental value. Just like to keep my baby peppy.

Any recommendations on the turbo. The guys @ the garage R doing the research into building up the the 14G into a 20G. But I'm concerned about turbo lag. The current setup starts to boost around 2500 rpm's.

Also, w/the fuel setup I plan on setting the 2nd stage boost to 15-16 psi

Piping leak. My TD04-13G has hit 16psi before. And I use the stock 1.5'' exhuast piping...

Thanks for the reply. I can get the turbo to boost past 15 psi on the 2ndstage of the boost controller. But it won't sustain the pressure. In 3rd (on the 1st stage of the BC) it'll spool up to 11 psi quickly & hold. But then around 6.5K rpm's the boost will drop off to 6 psi. It's a hairline fracture in the Drag manifold that is precipitating the custom manifold. I just don't want to drop major $$$ in to the manifold for a turbo that mayB having problems.
