The fuel pump will be fine but the injectors will flood the **** out of your motor and without a tune it'll run like complete dog **** if you don't wash the cylinders down lol. 42lb injectors are total over kill with a stockish car and normally require a good tune to have the driveability down in a car pushing enough power to actually make use of them so in your case it would be a complete f up in my opinion.If I upgrade the fuel system to get ready for future mods, will it be ok to add a 255 lph in tank pump and 42#/hr injectors? Will this change work ok and reliably with everything else untouched?
These cars like to be on the leaner side of things until you get into a power adder.I know this won't get any more power immediately, but will get car ready for some later so I don't lean out:rockon.
No, speed density require a retune after major mods and runs off of vacuum so once you change out the cam to something a bit more radical in so many words you'll have to have the car custom tuned and a new chip burned for the setup or convert to mass air. Mass air can adjust to bolt on's allot easier before requiring a tune to get the most out of it.Will the stock speed density and computer work as is with this mod, or will something need recalibrated? Of course, once I need, or if I need, to switch to mass air, I'll be sure to get one calibrated to match the injectors.
To up the injectors in a speed density car you have to have a chip burned for the mod.. maf cars you just have to match the maf sensor to what size injectors your going with.
Only certain longtube header brands hang lower then others.. some are harder to install and some arent. Some have clearance issues with the steering shaft etc where some don't. They aren't legal smog wise but yield a slight gain over the shorties but if you want to keep it simple go with the shorties.I'll put on unequal shorties and an o/r X pipe. The reason for these headers is the car is lowered 1 1/2" (forgot to mention earlier) and I don't want the long tubes scraping the ground.
stock headers suck balls.. they are tiny and crimped. You'll see the difference when you pull the first one off and can compare against your shortie headers.Will the aftermarket headers really flow that much better than stock?
Best thing to do with your speed density stock car is to start out small with the normal bolt ons like headers, x or h pipe, catback, gears, etc leave the stock cam until your ready to really dig into the motor.
