SR20 POWER

[GRIM_CASTWAY]

HOW MUCH POWER CAN THE SR HANDLE??

[Clarkbar]

ive have seen stock block, head with cams. gt2871 750cc. great tune pushing 392whp. not sure how high he was boosting

[Surge]

you can push a stock sr to 300hp easly

[Camo]

Its not how high, but for how long...it can be done though

[GRIM_CASTWAY]

300HP? CAN IT BE RELIABLE?

[Clarkbar]

yes.. if you keep up with basic maintenance... and build it right... any engine will last long... except ones heavily modified... bores, shaving ect. anything can go wrong!!!! keep it stock and tuned for response not power, if for power build for 600hp run it at 400.. get my drift?

[travis]

i wouldnt push more than 400 on a good motor 375 is about all i would personally run run on a stock block

[killakingquan]

1000 HP stock :)

[Cattman]

....1000hp on stock what?

[killakingquan]

stock internals and turbo duhhhhh everyone knows that lol

[Carlita]

you really are a dumb ass i hope ur kidding

[pete240]

1000 HP stock :)

[GRIM_CASTWAY]

IM SURE I COULD GET A RELIABLE 400 TO 475 HORSES OUT OF THE SR,I JUST NEED TO GET MY HANDS ON ONE,WE WILL FOUND OUT SOON.

[killakingquan]

lol yall are funny . n yea u can make a reliable one with the right parts juss depends on what your working with you know , gota have the right turbo and as far as wich power band you want , what kind of internels , u could always buy a tomiei block , lol but that cost , if u look up a drifter name tyler cox , he has a s14 it has a fully built tomiei block , should be well over 400 hp , altho he is selling it , it is rather nice

[mazdarati]

theres an old saying...

cheap-reliable-fast, choose 2 because you can't have all three

you want to get a reliable 475 out of the SR? not a problem, just be willing to spend a crap ton of money. if you want to make that power and have it be "reliable" you would have to shoot for building the car for 600 or more and then detune from there. at those hight numbers you have to start looking at the bearings, pistons, rods, probably a new valve train, basically you would have to rebuild the motor completely in order to keep it "reliable"

[killakingquan]

if you have the money anything is possible , but then again if u can afford to build a 400 hp daily u might as well juss have a daily and make that a track car , and a car to show off while rollin thru down town wit some girls lol

[killakingquan]
