how much $ will it take to get a v6 stang to 300 rwhp.. how dependable is the 3.8
and is 120,000 miles on a 3.8 worth it..
i have a chance to get a 96 with a v6...but i want at least 300 rwhp//

 

I would rebuild the engine then, super or turbo charge, if its a single port its gonna take slightly more work to hit 300 rwhp but it can be done

 

eh slap the blower on till it blows, 300rwhp is fine on a 3.8 but im unsure with the miles, a properly tuned 11 psi procharger with supporting mods until something happens then start with the build up

 

Sell all your stuff and buy a 05 GT, 300 hp and 87 octaine, then you have something to work with. trying to make 300 hp from 3/4 of a motor is not going to work very long.
But if you really want to blow your engine up , then a 125 shot will do it just fine.

 

HP=money

singleports can make alot of power but unported an 11 psi procharger will only give about 250rwhp and 280-290 ftlbs of torque which is really an amazing step from stock and with a good suspension setup and lighten the car can get you into the high 12's with the right gears

money. it all depends on which route you go a turbo kit can get you 300rwhp and torque a procharger with a splitport swap will get you 300rwhp a procharger with a 4.2L F-150 engine swap will get 320rwhp. there is alot of stuff needed though. fuel pump,MAF,42lb injectors,dyno tune,SCT tuner,detroit truetrac and 3.73's or 4.10's. off the shelf it will run $4500 at least. used parts can cut that cost in half but patience is needed to look for the parts. a home made turbo kit will get you there if you can do everything yourself. the best thing to do is a 100 shot wet nitrous kit with injectors and a good tune with 4.10 gears. it only good for about 250rwhp max on a singleport but over 300ftlbs of torque.

raw hp isn't the only equation. many guy's at 300rwhp can get beat by the same car with only 250rwhp because of a superior suspension setup.


120,000 miles if it was taken care of would be OK to adda a poweradder but you better off rebuilding the engine or throwing a lower mileage junkyard engine in it for $400

 

a stock 05+ gt will still only get u around 275 to the wheels

You are correct in your horse power estimate, However there is one sentence you may have overlooked, "then you have something to work with"

Making 300 Rwhp from a 3.8 is not impossible, Jack Roush was making around 500 when Bush were running V6. But his engines only had to last 5-600 miles and none of us are Jack Roush.
If you start with a good platform (like the 05 GT) then building is a whole lot easier.

 

god i hate people who type in bold.

while sn95's are dirt cheap, a fox body(before 94')5.0 would be a better starting point than a sn95. you also better check that the head gasket has been replaced, the sn95's had some major problems with them. 300hp is a lot easier to get with a split port, seeing as just a turbo will do the trick.

the engine has 120,000 miles, you will start to find yourself replacing a lot of things if it wasn't maintained properley. i would find a splitport 3.8 with low miles, it's like driving a brand new car and you geta 50hp increase. 400$ for 50hp isn't that bad of a deal. then slap on a turbo or procharger to the splitport, and vowla, you are at or arround 300hp.

but remeber...

 

m90 supercharger swap + boost juice... start with a pissy 120rwhp on a friday, get 300rwhp by monday

and the best part is if u got the tools plus do teh wrk, could get it done for under 1000 easy

 

God I hate people who hate people that type in bold And have a V6 Cobra?
