Increasing My Psi

[StevenR33]

I have a series 2 r33 gtst still running a standard side

mount with a 3 inch exhaust from the turbo all the way

through just wondering what's the max I can boost it to?

[BigDirtyJase]

Well you'll be needing a boost tee (urgh!) or a boost controller (yay) to increase boost...I would say safely you can boost it up to 10 psi on stardard equipment

[krzysiu]

Yeap 10psi

go on eBay and type in turbotech and buy it. Think it's $30

[StevenR33]

Thanks mate another question I want to use a manual boost controller

what would you say about that?

[VSPECT]

seen few guys boosting it up to 12psi but would advise it...10psi is safe but can put it to 12 for bit of booting....

[VSPECT]

dont like manual boost controllers....cant tell what your boosting up to until you try it out...recomend proper digital boost controllers....

Manual Boost Controller = Boost Tee = Bleed Valve. If you're going to buy one, get the one Kris recommended: Turbotech. Cheap and very reliable.

That's why you start off with it in the factory setting and adjust incrementally, as opposed to just winding it up and letting loose. Will take about 5 adjustments to get it perfect. Turbotech manual boost controllers are fantastic, never had one spike on me, ever.

with the full exhaust its probaly be boosting close to 10psi already , id go 11psi....

14psi is what you would put it on if u want to kill the turbo quick lol

12Psi is safe on stock turbo

i have GFB boost controller, never have issues with it at all.

i ran 12psi on my stock turbo, no problems. but be prepaird to buy some after market coil pax after that. also get the greddy profec spec b II boost controller its like 500 on justjap and it works a treat

[StevenR33]

i bought a manual turbosmart boost controller but dont know how many psi is each click anyone have a rough idea? im guessing all the way to bottom end would be standard boost just wanting to know how many more clicks to 10psi? if anyone knows thanks.

[Birds]

Here's an idea: buy a $50 boost gauge and save blowing your turbo

I would never install a boost controller, even electronic, on a car without using a boost gauge.

i've run 12 psi for the last three years no problems

[perzn_34]

if u run a am turbo but stock other parts except exhaust from the front pipe to the tip, would 14psi hurt?

[vspecIInur]

I'm pretty sure if you run am turbo, be prepared to upgrade a lot of things otherwise your standard setup is not going to last long. Most the time its recommended getting a tune done after certain mods. It also depends what power range for a particular turbo. Increasing boost means your fuel:air ratio changes dramatically with the potential of running way too lean.

i still had stock turbo but was running 14 psi with profec 2 boost controller,exhaust,pod filter,front mount and bov and kept getting fuel cuts,pump or injectors weren't keeping up foot flat and was like speed limiter was kicking in at 70-80 k's (well mechenic told me it was fuel system anyway)

[jjskyline79]

Fuel cuts at 1.3 bar????

yep. you'd be leaning out and even more so with the aftermarket turbo. would require fuel pump and retune.

there's only so much equipment is designed for, fuel maps aren't designed for large turbos @ 1bar thus lack of fuel = lean.
