Whats needed for my awhp goal on pump gas?

[Drifter27_04]

First off please let me apologize for the long post

Looking at my current setup what is needed to achieve 450-500awhp with pump gas for a decently tune for street/strip. Please suggest what I would need or not.

Current Mods:

DSM Link
Zeitronix Wideband

PTE 60-1 internal W/G
2.5" O2 / Dump to Atmosphere
Aeromotive FPR
SS -6an in/out fuel rial lines
2g Manifold Ported
Buschur FMIC 2.5" in/out tubing
10mm Magnacore wires
Fluidyne radiater
GM 3" MAF sensor (blow through)
MAF Translater
F.I.C. 850cc
Rewired 255lph fuel pump
3" turbo back exhaust
Greddy Type-RS BOV,
AEM Adjustable cam gears

Wiseco Pistons 8.3 c/r
Eagle Rods
Clevite Bearings
motor held all togather with ARP
Buschur O-ring Head
Crower springs / retainers
3g lifters
Cosmetic head gasket
BS removed
4 layer copper exhaust gasket
FFWD DKS2 cams

Shepherd Transmission Stage 3
ACT 2600 Street disk
Fidanza Flywheel

KYB AGX's front and rear
Eibach Pro Kit Springs

Parts I will be purchasing in the near future to meet my goals?

The turbo is being rebuilt and the exhaust housing is being replaced with another one to allow me to run a O2 External WG.......or would it be affective to remove the WG flapper and weld the hole where the shalf was?

Plans are to have a 3" (Tial 38mm W/G) recirculating O2 housing

Upgrading to a FP Manifold

C.O.P. setup or just going with a MSD DIS ignition and running the Magnacore wires....which would be acceptable to the HP gain I am looking for?

Tial BOV (maybe soon the Tial Q BOV will be released)

Will be purchasing a JMF (Race) SMIM w/ SBR Intake Manifold Heat Barrier Gasket

Debating on having my TB rebuilt and bored or purchasing a 75mm TB (can get a great deal on a Power Products 75mm Throttle Body)....would the rebuilt bored OEM meet my goals?

GM 3 Bar sensor or AEM 3.5....Would this allow me to remove my GM MAS blow thru Setup?

Would it be needed to upgrade the fuel line from the pump to the filter to achieve my goals?

If there is anything else that may / or may not be needed to reach my goal please let me know and all suggestions will be greatly appreciated as I am near the point to start ordering some of the parts.

Please note that I also plan on running 110 and higher boost (30psi) in the car on the weekends sometimes and at the track. And looking in making over the 500awhp make for sure,

that walbro 255 pump and 850's might be questionable. I'm not saying yes or not at this point just some thing to consider looking into.

I thought it maybe questionable but it would be nice to able to with the two. I would consider selling the 850's and getting a ser of 1050's and going with a dual 255 intake setup.

Go with a rewired Supra pump. Just a thought.

Not knowing much about the Supra pump how is the pump compared to the 255

 

[kelvinb]

Supra pump is about equivalent to the 190lph pump

No, that is the VR4 pump. The MK4 supra pump is slightly bigger than the 255HP.

My bad. I must have read some miss leading information some where because I know I didn't just make something up

Given that why down grade WTF

Nah serious I thought the 255 was good up to 500-600awhp alone

Whats with all the, "what mods do i need" threads lately? The supra pump is bigger than the 255, 450-500 on pump isn't easy. Meth injection would benefit you greatly. Stock ignition is probably just as good if not better than a COP setup. MSD is probably better, not necessary, but better. MAP sensors will not let you remove the MAS, unless you switch to speed density, which is a whole other can of worms. You can probably find the answer to all your questions if you look around a little. Anyhow, good luck on your goals.
