Most streetable power with an inline 6 in a 240

[Boostage]

I know this might be a bit of a general question, but for those who have done it or knows someone with an RB or JZ motor in either an s13 or s14. at what point is power too much for the chassis on the street? at what point even going WOT in 3rd gets hairy. 350rwhp,400rwhp,450, or 500+

what do you think is just too much for the street with one of these engines?

[illvialuver]

um for these engines? i think 666 -700 is very streetable.
a friend o mine streeted his r32 gtr with that much, but that shit was crazzyyyyyy, so i would say like 500

[adictd2b00st]

everyone is going to have a different definition of "streetable" but what i can say is imho that a 350whp s-chassis car is pretty much perfect for a street car.

yep, smooth idle, instant spool, fast, and responsive, but not obnoctiously "OMFG RACE CAR!"

[eastcoastS14]

no more than 300whp...any more than that and you start losing traction, and if its just your daily whats the point over 300whp in an s chassis is crazy fast

[turtle m3th]

From the majority of articles i've seen and people i've talked to that own these motors say no more than 600hp. It isn't that they will not withstand more than that on the daily it's just that it takes alot of fun out of driving the car because of the harshness. I've never driven in a 600hp+ car so Keep in mind this is what i've been told so I don't want anyone trying to take a hunk out of me for saying this.

[lflkajfj12123]

too much power means traction can break to easily and thats not good in a street car especially when dust or rocks are on the road, can't imagine it in rain or snow. my stock ka24de with bolt ons looses traction at times

time for bigger wheels ~~

[250sxdet]

I drove a friends rb26 powered s14. It put down about 330whp stock. That was pretty damn fun. I would say out of an RB, you can be in the 400whp range and sitll be streetable. At that power level, the motor will still be super resposnive. You can achieve that power by just turning the boost up and getting a good tune.

[eastcoastS14]

my last car put down 350whp.....it was pretty fast in 3rd gear and up, but lay on the gas in first or second or in high rpms in third and forget about it....the thing would lose traction pretty damn fast, the tires would skip and it would almost hop into the on coming lane so youd just have to point the wheel where you were trying to go and hold on....IMHO totally unnecessary for the street....300whp and under is fine because our cars are so light

[garbury]

Just got my gt2871r .86 running and it isn't even tuned too well yet. At 12 psi, I'm basically scared to give it gas on city streets. I'm guessing its only doing 290 whp but thats more than enough power to get into a lot of trouble very quickly.

Drivng with a t25 at 15 psi for a year was pretty fun and I thought the car was fast. I would never hesitate to floor it though and always felt in control. Now, I get shaky after a solid 3rd gear pull and my brain hasn't gotten used to the acceleration force so it freaks out. I can only imagine 400whp+ cars

wow! so 350rwhp is probably the upper limit of streetability for you personally?

[RUTH'LESSDET]

I think 350-375hp is more than enough power for street inline 6 or not

[fliprayzin240sx]

Well you already got my 2 cents...

[Otis Performance]

on a inline 6 300-350hp is the max i would push on the street.. to use anymore then that without killing yourself or anyone your going to have to go to the track.. i have around 450hp now no traction in 3th gear

[garbury]

Well, I will see how easily I get used to the power, I've only had it for a day. Basically you get through gears very quickly so if I stomp it in second gear the turbo spools and I slam to 60 within a second or two (I have no traction issues). On city streets with limits of 35, its kinda easy to get into the criminal speeding/reckless driving area extremely quickly. I've gotten a drag racing ticket before (wasn't racing anyone) and know how easy it is for cops to give you heat for having a modifed jap car. I have anxiety from this so excessive speeding makes me feel very uncomfortable.

If I have a straight road and no fear of police, I wouldn't hesitate to stomp it, just the car pulls really well and third gear doesn't last too long. I would totally street a 400whp car, its just driving skills have to improve tremendously to handle the power. Also, once you get so much power, actually using it without endangering your life/record seems quite a challenge.

[Full-Lock]

i have 485whp in my rb26 currently...i love it. daily it everyday too. more power would be too much. it used to have 650whp but that was too much.

[bardabe]

lol i know what you mean. ha ha my RB is probably pumping close to 300 (no dyno sheets yet) but if i give it anything more than 30% throttle it just wants to skid and slide. and the fact that I got 205's isn;t helping. Time for 5 lug and better wheels.

[unlegendary]

honestly it comes down to where u live at. if it rains then i hope you fail at life. if your at a place where the environment, weather, traffic, and roads are good then 450whp would be cool depending on your tires and suspension set up.

[Full-Lock]

i drive my car just fine everyday...you can daily something with 300whp and you can daily something with 700whp just as easy. all you have to do is just go easy on it. just watch the throttle and you'll be fine.

[eastcoastS14]

^^ i demand pics of your car so I can put this box of tissues to use

[Full-Lock]

haha

dont worry, the oem body shit is going soon

[lflkajfj12123]

hey topsecret ive got to see your car in person someday hah i sold that s13 i had and bought a s14

you going to be taken your car to any shows?

and barbade 205's lol omg i can't even imagine

[Antihero983]

hmm good question....

from what ive heard and gotten from talking to people, 300 to the wheels is good for daily driving.

however, it depends on what you consider street/daily driving.

do you sit in traffic alot? do you drive more on weekends or weekdays?

[eastcoastS14]

haha

:wackit: :wackit: :wackit: :wackit:

what are your wheel specs btw?

[fliprayzin240sx]

I say 2 stage boost controller...one set for atleast 400 on low boost and 600 on high boost when you just wanna destroy the car on the freeway.

[Full-Lock]

thanks

haha yea i am...but 235/40 on a 9 looks soooooo dumb...too big of sidewall

and barbade 205's lol omg i can't even imagine

yes it's horrible. 225's are on the way though. =) I had to downgrade back to my old 15" wheels, but hey atleast they are 7.5 so I'm gonna run 225. yeah yeah they look oldschool not trying to be "JdM TyTe" just need traction..... badly.


topsecret. your car is gorgeous, Excuse me but im gonna air my personal opinion. and I think that the stock body lines look beauty full. just add the JDM wing and Rear valences. you sir are Golden. looks very damn nice.

[lazierhobo]

streetable power totally has to do with how far you are willing to go for supporting mods. i mean if you dump massive money into suspension stuff, wheels, tires and brakes. you can run massive power without serious traction problems if you want to spend serious money on rubber.

[steve shadows]

no not really

the best suspension for big power if your going in a straight line, is bare bones stock, just get some good drag radials.

the most driver killing suspension is the expensive stiff stuff.

whats the most powerful car you have personally driven.

don't fucking lie.

most people come on here saying (400whp goal!)

and then you hear about Hulk's kid slamming into a pole.

going from a ZC in a EF hatch to a top mount dyno tuned RB26 in a s13

is like going from a flesh light to the grotto and getting a 3 way hand job and trying not to bust.

only if you bust early you die

ok so it wasnt the best analogy...

[lazierhobo]

i didnt think he wanted the power for straight line. i thought he just wanted to drive hard on the street.

no matter what power, if you dont have real tires, you cant put any power down.

[Sir]

ok so it wasnt the best analogy...

Yes, yes it was the best analogy EVARR!!!!!!

[steve shadows]

yeah but thats all you need (so et streets in the back)

some crappy khumos in front

lots of power and some better brake pads

i used to do 140mph runs all the time like that

it didnt feel that stable but I had way more traction that i do with stiffer better gear all over the car sprinkled on the suspension etc.

think about it

shitting is always easier with a loose stool

ok another fucked analogy.

yeeeeeesh

[garbury]

lol at Steve, thats some good stuff. Wish I was in Cali so u could tune my shit.

Update for me. I have driven the turbo (gt2871r .86) at 12 psi for 2 days now and it doesn't scare me much anymore... I bumped it to 13-13.5 though and turned on the boost controller and set the gain up kind of good and it scares me again, lol.

I would say the most streetable power you can handle is whatever you've got. You just have to get used to it in small increments. I remember 7 psi bone stock in an sr was the fastest car I had ever driven, and it scared me. Then full exhaust gave me enough power to feel uncomfortable for a few minutes. Then 15 psi on the t25 scared me again for a week or so. Now this turbo is the same...My advice, don't upgrade at all because boost is extremely addictive. I'm already visualizing a rebuild on a spare block (which I dont have yet) with a massive topmount.

I have a fully rebuilt suspension (tanabe coils, tension rods, new bj/tie rods, rucas, and es bushings throughout including subframe). Also I have the 32 mm z brakes to ensure proper stoppage. Edit: I also have falken fk452s (AA traction rating) in a 245/40/17 so I haven't broken traction yet except for full throttle on turns. If you set your car up right, it is amazing to drive a machine that is tuned to your specs. I can only imagine the high dollar build, clean, rb26 240s

[drift freaq]

300-350whp is street-able in a S13. Hell you could probably push 450whp. Thing is most of the people on here don't know how to handle a car like that. Now Steve Shadows, Topsecret and Bardabe happen to know how to handle fast powerful cars, because they drive them.
At the 300-350 whp the S chassis does become god awful fast. At that point you really have to take into account the other drivers around you. Nine times out of ten they have no idea your capable of that kind of quickness and speed.

In case the OP is wondering I drive a 300-330 whp depending on boost RB25 powered S13. Of course I don't drive it everyday because the gas consumption can be impratical imo. hehehehehe
I am building a stock 300hp VQ car at the moment. Yes I want to push it above that with mods but I like to do it increments, get it in get it running then play with it.

yeah gas milage does suck at full boost, however if you stay out of boost the motor still makes more than enough torque to move the car the speed limit +/- 5mph and my gas milage then is not too bad. :D. ha ha Now Here Mr. Drift freaq has a very nice RB25 (or is it 26) street car that he dailies he also knows how to handle this kind of power.

[Z U L8R]

if i use the definition of streetable as being able to put any gas station's high octane (93 in GA) in my car and going for a spin without any qualms whatsoever i'm gonna hurt my motor, then i'll say [email protected] aka my low boost setting. if having to use race gas doesn't define "streetable" then 900-1000rwhp is definately streetable, here's how my friend's twin turbo camaro hooks on the street

view from inside the 800hp mustang
http://media.putfile.com/Twin-T57-0...win-T60-1-02-SS (http://media.putfile.com/Twin-T57-03-Cobra-vs-Twin-T60-1-02-SS)

view from inside the 900hp camaro
http://media.putfile.com/TT-Cobra-vs-TT-SS-

when my Z was 300rwhp it was right at the traction threshold with 245/60/14 bfg all terrain tires. BUT that was with the 4.11 open differential.

with my 3.54 open differential, i can roll on first gear in low boost and i'm back at the traction threshold , it hooks great on street tires.

all this "streetable" nonsense goes with definition. micky thompson makes et streets, you can get nitto's or you can get futura's. you can make 800 rwhp or you can make 300 rwhp, depending on your set up and how you drive traction may or may not be an issue. the question about what is "streetable" is vague and all relative, in a nice way. it's a matter of what someone's definition of streetable is

if you're talking about reliability then that's a whole nother story. all that is relative on whether you've opened the motor or not. if you list what you're going to do with your car , then ask for advice, that would probably be a lot more useful to you.

must be the 2.0 litre.

or the tuning :rolleyes:

i wont lie, its not economy car status though haha.

Streetable power = shift at 3-4k rpm.

My friends dyno at 190 all the way to 500+hp
They all drive in the street. You dont have to dogg it everywhere you go.

[Koopa Troopa]

This thread upsets me in so many ways. The Japanese car people of the United States, not saying everyone just generalizing. Have this sick, girlish way of what a "streetable" car is.

"OMG I can't have a twin plate becuase the engagement is too harsh and the clutch is noisy". "I can't use a 2 way or welded diff becuase it clunks when I drive slow", "I don't like such and such exhaust because it's too loud", "Having an idle @ 1200 rpms is too rough so I can't use such and such cams"

I see posts like that time and time again. For you sissies too afraid of man parts on your car I hear golf is a hobby just as expensive and is a little quieter.

Streetable is whatever I feel like driving to work. Which happens to be the car in my sig..

[daryl337]

zomg. 863.45 hp is my limit. as soon as I hit .46 all hell breaks loose. jk.


I am personally a speed nut, and dont mind if things get violent. But that is me. Some people are more into the comfort and safety. I am more into the violence and adrenaline rush on a day to day basis... if I don't want to go fast, I don't put my foot into it... but in times I do.. I want it to be readily accessable for me. :)

[bigOdom1]

only get on it when you are expecting the power you have. thread is really stupid

idk man that's Kinda high I shift @ 2.5 all day. 3 when im in a rush. ha ha no need to go that high for me.

[trsilvias13]

I have a stock ka. driving at 2.5k seem really slow to me.

if you want streetable power, dyno you car and learn where to shift. If you have turbo, shift born boost starts to build. Its not that hard.

[bardabe]

I have a stock ka....
that's why ha ha I'm not being an ass or anything just yeah, the powerband on the RB and the KA is completly diferent. when ure at 6400 RPM's making like 130WHP im at 4K or so making similar power.

http://www.youtube.com/watch?v=KDdkz4JalG0&mode=related&search=

that's stock. I got a few mods and power adders so go figure. you just gotta know how to drive. learn your car. I say 350hp is very fast on an S-chassis. I've driven that much power, (Indolent's RB26) and it's not hard id on;t break loose or anything unless i give it the gas it needs (like 25% throttle) to break loose.

[steve shadows]

225? not worried about understeer in that beast?

thats the point of insane HP

dont break, just oversteer.



more power more oversteer.

at least if your car is balanced right, and brake bias is set up properly.




*honestly*

to cap off this thread, and because ive had a lot of experience with 240sxs with all different power bands and HP levels on the street over the year, I would say 300whp and 300ft lb of torque is the best combination for the street.

Nice square very responsive and with the right driver in an s-chasis will pull 12.40s.

The nice thing about this power level is you still have some sort of traction when you want it and with the right turbo sub 350hp ranges

you can break loose if you so choose pretty easily as well.

once you get up to around 375+whp

You start needing very sticky tires to survive an exit acceleratiion from any increasing or decreasing radius apex on power out.

For example at 400whp in any gear other than 4th, exit accel im just drifting and oversteering now. This is true 400whp near 350 ft lbs of wtrq + I dont even know how it will act with a propper clutch, with even more power getting to the ground.

R compounds are already in my future.

If your comfotable driving around on tires under 200AA treadwear all the time, then man up. Its a blast to know you have as much power to wieght ratio as a GT3 Porshe

[yaba94070]

my car had around 280whp when i first got it.. and it had enuf traction to still have funn, but alittle more couldn;t hurt...
im going with 400whp now i will let ya know after i break my new motor in..... in liek 450mile so give me a week
lol

[Boostage]

Let me define what I meant regarding streetability. I meant, having so much power that you can break lose a good tire. in 3rd, like a drag radial for instance. I know heavier cars like supras and camaro's hook alot more than 400 foot lbs, but the S chassis with an I6 still clocks in under 2900 lbs. I figure a light chassis and light ass with the typical 4.xx rear end and 17's that things would get a little squirly around 400 foot lbs. thats what I am asking.

when I said streetability thats what I mean, dont care about reliability, fuel, clucth harshness or none of that, just how much power is just too much to control with a big turbo motor in these light bodies
??

[EDacIouSX]

i would assume it also depends where you live... streets in vegas are huge and paved nicely. my block (i'm in l.a.) is total crap. pot holes everywhere.

with nice ass streets i say the sky is your limit. with l.a. streets i say you're limited b/c the streets can get dangerous with all them pot holes and deformities.

but in reality the limit of how much hp is too much is what you want.

am i making any sense?

[cyclone92692]

Well IMHO any motor bigger than 4 cylinders in an s13 or s14 is too big. Car is not made to have than much weigth in the engine bay(you can make it happen) but the weight distribution is not near as ggod as sticking with 4 banger. I stick with sr20 or ka24. but as to horsepower that's all up to how comfortable of a ride you want!!!! that's just my preference... my 350Z with greddy twin turbo set up put down 355whp with 6 lbs of boost was great and even at 450whp(ass swung around like crazy)on pump gas ran great but needed BKK so it all depends how comfy you want your ride....
