Hello everyone, and thank you in advance!

I recently purchased an 02 GT 5 spd. I have installed a Borla S-type cat back, a K&N C/A kit, and a Pro 5.0 shifter. I would like to put a suspension and SBC's on next along with a TFS 70mm throttle body and TFS intake. I need the car to have @ 300 hp and run LOW 13's in the 1/4, NA! There will be no blower on this car..............ever! Maybe a 100 shot bottle when other mods are complete.

I would like to hear any and all suggestions!

No blower...ever...?? Why...?? Anyway, I'd say to get the TFS intake with the twin 57mm inlet as opposed to the single 70/75 mm inlet style. Maybe a set of 3.73 gears. A nice cam (I always hear good things about VT Engines cams). A timing adjuster and good tune. And finish the exhaust with some LT's...

+1 On the Lts...if youve already done that much to your exhaust I'd just finish it. Id skip the Tb and go for some better heads!

To get 300 hp to the wheels NA is going to take a little bit of work, but nothing too extreme. A set of long tube headers, throttle body, plenum, ignition coils, cams, and a good tune should get you putting down some good numbers. If you do your heads as well, youll be at your 300 hp goal no problem.

you shouldnt rule out a supercharger though. you could run it at only 6 psi and still get the numbers you want.

Don't forget about gears either, while they dont add power, they seriously wake up our cars.

can u put a supercharger on a stock mustang? if not upgrades are needed?

I'm kind of confused if this was a question directed to the O/P or what.

You can supercharger a stock mustang but you need to upgrade the fuel system. if you want to make a lot of power you need to go build the bottom end of the engine.

i was just posting the question in general. what needs to be built up on the bottom end? as for the fuel system, u mean just a new fuel pump?

DeathRattle

You can supercharge a stock mustang and upgrade the fuel pump and you will be fine if you stay in the 400-500 hp range. A 255 lph pump with a KB boostapump will handle a good amount of power. Building the bottom end means stronger rods (like 4340 H-beam) and forged pistons. Some like to even spend extra for a forged crank but the cast iron cranks are stronger than people give them credit for. I think they can handle over 600 hp but I wouldn't try to push it much further than that...If you're gonna push 20lbs of boost and a 100 hit then you want a forged unit.

450rwhp is what alot of people say is the max. but if it were my car i would keep it close to if not a little under 400 on a stock bottom

DeathRattle

You're probably right defcon...some people make over 500 and have no problems while others make a little more than 400 and snap a rod on the way home...better safe than sorry right...??
