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?

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.

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.

These cars like to be on the leaner side of things until you get into a power adder.

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.

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.

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.

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.

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.

Will the aftermarket headers really flow that much better than stock?

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.

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.

I wouldn't worry about snapping axles yes you don't even have the suspension setup plus the t5 is the weak point then the axles plus my daily driver has all bolt ons minus a power adder and the three years i've had it, it's always had dr's on it and has been ran regularly

Hey Ryan, do you use DR's at a lower pressure at the track and run them on the street at a regular pressure (25-30psi)? I am looking for a tire that will hook decently, but still perform in turns. Are you using a BFG, Hoosier, etc.?

Yes that's what I do.. I've never ran bfg's dr's but heard they sucked but can't atest to that myself. On my dd I run nitto 555r's which aren't too bad of a dr but has good wet traction and on my turbo car I run mt et street dr's which are great but horrible in the rain.

Did you replace the t5 with another t5 or a tremec, etc? I know the T5 is weak and I'll probably end up replacing it sometime. Is it easy to switch to a 6 speed tranny, T56??? With the 3.73's at highway speed, it would be nice to have a 6th gear.

In my dd I swapped in a tremec 3550 and haven't had to worry about it for a few years now. People love the t5 because it's cheap and easy to rebuild or easy as hell to find cores plus they weight allot less then anything else out there.

My turbo car I did the t56 swap, it wasn't too bad. I still haven't delt with the speedo though and it's been two years lol but the swap was well worth it. Only point of the swap you have to deal with is the driveshaft. I forget now but you either have to lengthen or shorten the shaft but if you search around you'll find the answer quickly.
