Turbo vs. Nitrous

Didn't find one of these on the search, so here goes...

So, taking in mind the price, the quality, the effects on the engine, and the power which would be better, or is it all a matter of opinion.

I used to think that, regarding nitrous, you couldn't get a bigger bang for your buck. But recently, after doing some research with my mechanic, I think turbochargers (although a but more pricey), are far superior to just nitrous. Lets look at why...

Nitrous is a set modification, meaning you after the install you can't really change the amount of nitrous that is used (50, 80, 100 shot etc...). Also, you have to refill it, which means you'll never pay off the modification, you will keep having to pay to use it. Which also means, you won't have it when you need it sometimes. And at around 5-6 dollars a pound, that will add up real quick. Another reason being, it is a mod that is not instant, not to say that a turbo is because of lag, but meaning you have to open the bottle, and wait for it to warm up to avoid detonation. Again, you won't always have it when you need it. There are other downsides also, but lets not forget the good sides, when you floor it your gonna go fast...hahaha.

Lets look at Turbo...

One time thing. You pay the price to have it and you have it. Stock maybe 6-7 psi, but with little mods, not necassarily building up the bottom end, you can boost in upwards of 12-14 psi, perhaps 16 psi at most, depending on turbo and the safety of the install. But with that little "built in wastegate" that most turbo kits have, 15-16 is tops. However, with the little mods, (intercooler, bov, thin head gasket, head studs, injectors, boost controller etc...), you can up the boost which means more power. Another plus is, after a certain rpm, the power is really uncomparable, despite the lag. Efficiency is another, with a turbo it really doesnt matter what engine its strapped on to. Look at the Dodge Neons, that engine is horrible, but the cars are damn fast. Which means its a good mod to do to vehicles that want power with the original engine (ls, d series, etc...). Safety, most mechanic shops are not the best at safely installing nitrous kits. The place I go to, RaVer Motorsports, charges about minimum for a nitrous install about 2,000 dollars. May seem steep, but its not as expensive as a new engine, after you blow yours up due to a faulty nitrous install. And there work shows for it. Not to say that you can't blow an engine due to a turbo, but it's less likely. Power, nitrous gives you power, but turbo will give you more. It's been proven many times, dyno charts, races...whatever. You all know it, haha.

If anyone has any info to add to the list go ahead...

My plans:

Hondata S100B (with boost) - already have, not installed
ARP Head Studs
Mugen Thin Head Gasket
Spearco Front Mount Intercooler (the big one ;))
Greddy Turbo kit, smog legal... (just for the tests, I live in Cali)
550 cc injectors
BOV, not sure of brand, havent done research yet
Tuned the hell out of...

I plan to get about 240 @ the wheels, out of my B16 with no internals, and not built bottom end...any suggestions about the setup are welcome...

yeah nitrous is cool for drag racing i guess but turbos last longer than a few seconds at a time, also search for the pic that melt (i think) posted of when a nos bottle exploded. yikes!

man if a shop wanted to charge me 2k for a nitrous install I would pick up a tube of ky. spending that 2k + another say $500 for the nitrous kit your already 3/4 of the way to a turbo kit. slap on the turbo kit, good luck with the above 12psi on stock internals, hope they know how to tune very very well.

for the sake of your wallet and the fact that you live in Cali go with the turbo kit man.

Spray is bad on ye' motor and isn't very cool, IMHO. Well it is when you do spray, but other than that you're going to have the same power.

Turbo you get power when you spool and you don't have to refill it =)

BTW.. you want a THICKER head gasket, not thinner. Thinner raises the CR.
As far as BOV's go, they do the same thing.
Also consider 440's I think that 550's are overkill.
Lastly, get an external wastegate. Internal wastegates are crap =)

GReddy turbos have an internal wastegate, no matter what...you can send it back to them and they can remove it as well as enlarge the turbine. And as far as the 2K nitrous install, that includes the kit as well as bottle heater, remote bottle opener, guages, and just about everything to make nitrous perfectly safe. I can justify the price because I know the shop owners really well. And going turbo, you do want a thick head gasket to lower the compression, I miss typed it last post. And nitrous is not bad for your engine if it is installed properly, and you do regular maintence (spark plugs, timing etc...) Most people have the mind set that nitrous blows your engine up no matter what, this is because people install it/ use it wrong.

And as far as a nitrous bottle blowing up? Nitrous is not flammable, so it can't blow up. The top of the bottle may have come off causing the bottle to fly around at very fast speeds, haha, but nitrous cannot "blow up".

look at this too, with nitrous you can see the same gains as turbo, but with nitrous you only use it when you need it... which means it's not doing damage to your motor when you're not using it. turbo you cant shut off so you're constantly damaging your motor. you wont need the hp of the turbo for daily drives or you're nuts.

And as far as BOV's go, they're not all the same. HKS makes a SSQV, super sequential and there are different diameters, and what not...

i personally think no2 is dumb...
its too hard on your engine and if you get caught with it you could have your car taken away.
i think nitrous it there to say you have nitrous (and also for those who just love to swap there engine... all the time)

:werd: for day to day driveablity Nitrous Oxide is the way to go. Armed and open you got power. Off and you're just riding around with a little less trunk space. You want on demand? Get a remote bottle opener. Armed and open, and ON. NOS is crap though. The solenoids are always wearing out and fuel pressure is increased by restricting the flow of the fuel which increases the pressure but lowers the volume. If you got the money look into Venom or Zex

i have one of the computerized venom kits on it's way for my car. i got it brand spanking new for $200 and i dont plan on installing it untill my tickets drop off and i feel comfortable going to the track.

you still have to wait for the bottle to warm to the correct temp. which could take a while, just because the bottle is open...doesnt mean its ready, and at a stop light race, thats no good

there is nothing good about a stoplight race... nothing at all. if you're going to talk stupid like that go for turbo. remember that once you turbo, if you dont plan on buying all the extra's for it right away then you will need to re-learn to drive your car. warm up and cool down times are necessary for a boosted beast unless you like cracked/warped turbo's.

thinner Headgaskets will raise compression.

oops. i confused myself. UndercoverSI was talking about running a thin headgasket to lower CR.. my bad

just wanted to set a couple of things regarding the Nitrous section of your post

1) you can change the amount of nitrous used (pills)
i see it no different then having a manual boost controller.
there's fuzzy logic for turbos...the Venom VCN2000 has programmable modes

2)you do not have to warm the nitrous bottle to prevent detonation.
detonation will not occur if jetted properly and you do the recommended 1-2 steps colder plugs.
remember as the nitrous flows the bottle will naturally get colder. i dont see it being warmer will have a SIGNIFICANT impact. a warmer bottle will flow better tho.

just remember.
Nitrous doesn't blow engines, stupid people that use nitrous blow engines.

that's a common mistake, people think turbo's arent bad for your engine if you're only boosting 6 or 7psi when in reality it is constantly damaging your motor. there's tuning you can do that will lessen the damage done, but the same goes with nitrous. the difference is that you dont need a 200hp civic for daily driving, the nitrous is used only when you are racing.
