can someone run by me a quick list of mods to run 8-10 psi?

IC
HP Fuel Pump
Bigger Injectors
Standalone Or
Bandaids
Such as Timing control, 02 clamp, etc.
With 10psi I would rather want a standalone though.
A Bigger DP would be helpful.
A helper Spring

Thats all i can think of. Im tired.

hey pai your still around eh? Sweet. Oh and what do you mean by a "helper spring"?

it's a spring that goes onto the internal wastegate and runs parallel to the wastegate actuator. It should help with keeping a steady pressure instead of overshooting your target pressure and settling down towards redline.

Of course, I'd highly recommend going with a better actuator. I upraded to a gt28 wastegate and it helped with both spool times and controlling the boost levels across the rev range.

will a walbro 190 and 1.8 inectors be good for 8 psi?

yes.

then you gotta tune the pressure a bit.

how would you tune pressure with the vortech diff disks?

FMIC, 1.8inj, MSD Timng Controller/Bipes, LC-1 w/ gauge for tuning, boost gauge, Begi AFPR, 255LPH HP fuel pump, boost controller.

Bigger DP/exhaust would help ALOT.

If you start seeing boost drop off, and aren't running INSANE RICH, you will need a helper spring. Too rich and you start losing exhaust velocity and it won't keep the turbo spooled up. I found that out the hard way this week.

They have a disk set that lets you go 2:1. 4:1, 6:1, 8:1, and 10:1. With 1.8inj you will probably end up using the 6:1 disk.

so you say the walbro 255? but other ppl say its overkill which one? how far can you go with the 190?

For the amount of money they charge for the set though (and for that matter each disc) it's probably worth it to just buy the BEGI add-on regulator for $199 and get rid of the Vortech. At least, that is my plan if I don't man up and do MS.

See the FAQ. Section 4.

190HP should be more than adequate for anything utilizing the Greddy turbo.

$90 for the 255lph HP if you are interested.

may want to upgrade your clutch depending upon how new it is.
