Review my plans please.
Review my plans please. After a long time of part collecting, and my recent purchase of a APS kit, I am almost ready to start throwing all of the parts at my car.
Please look over this list, and let me know what I am missing if anything.
Fuel System.
Racetronix plug and play pump assembly.
1998 V6 firebird fuel lines (return style)
1998 Corvette fuel rails with front mount regulator.
Hoses/Fittings for install.
60 # injectors.
(for a boost referenced fuel system)
Tuning/Gauges
Wideband in car.
EFI Live w/Roadrunner swapped 99+ PCM.
Boost Gauge
Fuel Pressure Gauge
Clutch.
3000 miles on a LS7 clutch/ls2 flywheel, new slave.
Forced Induction.
APS Twin Turbo kit.
Spark Plugs
NGK TR6
The motor is a 100,000 mile stock 98 ls1 motor, and I know I need valve springs, what springs are reccomended for a mile 7-8# of boost setup.
Thanks,
Ryan

you can probably use comp 918 springs depending on the size of your cam but I dont know how wellt hey react to boost. You might want to look into some dual spring like manley or something else.
And just out of curiosity, why would you use fuel lines from a stock v6 firebird? I would think they would be smaller then the v8's fuel lines since it doesnt make as much power.

I think you have it covered.
I would agree with the above on the valve springs, go for the duals and not have to worry about it.
Not sure what the consensus is these days but back when, when I put my stuff together, hardened pushrods were always part of the recipe. Not sure if you may want to add that to the list or not.

Only pushing 7-8lbs I would leave the fuel lines alone. If you want the bling factor get some aftermarket rails. Just remember -AN fitting get expensive quick.
My car will be done by spring and I'll be running 918's, just give'm time to warm up to temp before taking her out. If its going to be a while til you forge the motor you might think about getting some 317 heads to lower the compression alittle.

This is where I got the idea from for the fuel lines. The reason why to use them, is the stock deadhead system the injectors get smaller under boost, since the pcm cannot measure boost and alter the injector slopes. I know that 99% of people just add more air to the PCM calculation to compensate for this, but I want to do it correctly, and have the fuel system boost referenced, so the delta pressure stays the same once your in boost. Using the factory parts eliminates using tons of AN fittings, and everything is already bent into place for install.
... I posted at the same time, Thanks Blackbird.

haha yah within 1 minute. btw that setup works great. we did it on my buddy's TA (same pump, lines, injector,etc..) and that plus a splash of meth has gotten the car into the 650rwhp range with no fueling issues.
just read your sig, his is a bright Red 98 as well!
