More HORSEPOWER

Whats yup guys I"m new to this website .It looks pretty good and informative about Spec V's in general.Well my curiousty is about how's the proper order in putting aftermarket parts to gain more horsepower.I"m looking to obtain hmmm.....possibly maybe 265-300 or even lil more.I"m running with a Greddy exhaust system , a AEM cold air intake and just recently installed the Tornado device if anyones' heard of it.Trust me guys the thing works. I'm assuming I gained maybe 20-25 horsepower and the car is 175 horses stock.I would like to put a body kit and new tires and rims along with my modifcations.I"m more concern with the engine first before I do anything exterior projects.If anyone can give me help with what I should get first and then what goes next?I"ll buy you a beer who helps me....haha! I don't wanna blow my engine you know.I wanna do this right and get good results....Thanks..................later people

I have a question about that tornado thing? What is it? and where do you install it? Also I think next thing you should do is put a header into your car. It gains a lot of hp and Hotshot makes a really good one.

whats yup bro well you can install it by the gastankmanifold the very begin part of you cold air intake.Its fits tight inside the tube and doesn't jerk or loosen.It give you instant power/horsepower yup to 5-10 horses and good gas mileage.

It's a little aluminum device that sits inside your intake "spinning" the air that passes through. They claim that this spin forces more air into the cylinders and gives you more power, but it's all a load of crap. I'm too lazy to go into the details of why right now, but if you want I'll explain it in depth.

1) you aren't going to get 265-300hp without adding a large turbo kit and rebuilding the internals (read: over $10,000 installed)
2) You didn't gain 20-25hp from the tornado, you obviously don't have any idea what added power feels like, which leads me to believe you have no idea how fast a sentra with 300hp will be, you're just thinking that might be a good number to shoot for since sports cars come with ~300+hp.
3) Forget about crank hp (the advertised hp), and focus on wheel horse power, it's what really matters. Stock the qr25 (your engine, if you didn't know already) makes about 145whp. Even with thousands invested in bolt-ons you will never break ~170-180whp, and that's with i/h/e, cams, etc. If you want more than that you have to get N2O or a turbo. On stock internals the most you can push is ~240whp, any more than that and you start snapping rods. If you want more you need to upgrade the internals, which will cost several thousand dollars.

Oh ok I got you bro I have other aftermarket parts in my car.I'm not saying the tornade gave me 20-25 horsepower........LOL but with everything I think I gain about that much more.Well 265 lil more be good not exactly 300 if its gonna cost $$$.I know you know more about engines then me.So what do you suggest I do first in your opinon before anything?would changing the electric fan and lil minor things make a big or minor difference etc etc.I already have the tornade,cold-air intake and exhaust system.......thanks man

The next step is a header then, with an intake and exhaust (which probably added 5-7hp together) you're looking at maybe 10hp from a header. Go for Hotshot, AEBS, or Nismo for a header, anything else is a ripoff and will crack after a few months, or not even fit in the first place. After that, a lightened crank pulley, motor mounts, short shifter, and cams all come next, in whatever order you want. An air/fuel controller or flywheel would probably come next if you don't go for N2O. After all of that you're looking at maybe 180whp at the most, which is good for mid 14's in the 1/4 if you're a good driver.

Hmmm that sound good 2 me...I don't want bolt on cheap shit u know....lol...I was thinking maybe those upgrades too I'll follow it hopefullr maybe in a few months I can pull off those upgrades.I wanted to ask what do you think about those chips that suppossed to give you more improvement power.......like the VENOM CONTROL MODULES or those AIR FLOW CONVERTER BY APEX YOU KNOW COMPUTER TUNING AND HOTWIRES? Thanks alot bro.....ill keep you updated.......I"m luis

[sr20de4evr]

they won't do a thing

The only electronics that will help you at all are a reprogrammed ECU, which isn't made for the b15 sentra, or an air/fuel controller, which wouldn't do anything until you get it tuned right, which would take a couple hundred dollars in dyno time plus the cost of the controller itself.

yea bro I looked into the parts lately.It good shit maybe next month I start getting my headers and etc etc.So with ur suggestion on parts ?How much you think overall my car will make in horepower....in ur opinon with everything in stall with intake,exhaust, cams,pulleys,,,,,and the car is 175hp out the factory........etc etc......?thanks bro......luis

[sr20de4evr]

Well for one stop thinking about everything in terms of flywheel horsepower. It means nothing really, and all it will end up doing is confusing you. In fact the only way to even test your flywheel horsepower is to pull the entire engine OUT of your car, hook it up to an engine dyno, and go to town. Actually stop thinking about it in horsepower at all, flywheel or wheel. We aren't driving high powered turbo cars here where a small change in the a/f ratio will give or take away 30whp. The power gains from bolt-ons on our cars are miniscule at best, I mean you're looking at between $50-$200 per horsepower here. If you start looking at it that way it will only make you stop modding.

The best way to think about things is in 1/4 mile time, mainly because power means nothing with an idiot behind the wheel, or in a car that weighs 8000lbs, and your 1/4 mile time takes that into account. With i/h/e, crank pulley, and cams, You're looking at mid 14's if you're a good driver, of course if you're a bad driver you could be in the 15's easily.

whoa i would think that tornado thing takes away hp. I think it juss gets into the way of the airflow and who knows if it really spins on the inside. I`d take that sh!t to the dyno. Wait...how much did you blow on that tornado thing?

Ummm well bro about 65 cash$ at a store here in long island close where I work.Its a import store with kits,lights all that good stuff.If you buy it online it will be about 75$ i think or 65$ with shipping and handling.UMm its makes performence/power lil better and gas mileage lil better for as well.Not everyone agress it works and my friend felt a difference in the acceleration.It doesn't spin in ur cold air intake just kinda latches on tight inside.The airflow is was spins that what they say.Try it doens't hurt bro.....luis

hey sr20de4evr ehy man .Well I"m gonna follow on your suggestion for upgrades in the engine.I"m not trying to go extreme bro as for as horsepower but like I said i just want more power and better performence.Maybe Later on I'll ask for your advice on turbo and shit in year or too.How much you think i'm looking at for all those upgrades you mention but good brandes.I"m single and work for the post office so it isn't a big deal....lol.....$$$...thanks bro....luis

[94sentragtr]

wow thats a lot of money B. I might have to try it out myself. I heard people say those were garbage but ill look for one sumday and try and see for myself. Oh yeh...you should go with headers and pulleys. Then if you got the dough get some internal work done.

i dont know if they have kits for the newer years but you can e-amail them to find out. dont bother with all that bolt on bullshit if you really want more significant HP get the turbo kit with 8 psi boost which will be fine on stock internals. However I do recomentd changing to a race clutch before installing the kit. for $3600.00 you get the complete kit with everthing you need to install a turbo kit the right way. Think about it if you buy a decent header its gonna cost you around $800.00 for this car. The only other thing ud buy for it is a 3 in. cat back exhaust to compensate for the higher flow. Add up all the bolt on bull shit ita gonna cost you 3/4 the price of the turbo and you will get less than a 1/4 of the HP gain. its a big project but do it right the first time and you will be happy. I don't know how mechanically inclined u are but its reall not that hard to install it yourself. Honestly if u have access to a lift the clutch is a piece of cake in these cars. I've done clutches on civics before this one looks easier than that.
