NOS on 5sfe?

Virtuex91 · 04-23-2009, 12:00 AM

If properly installed and used correctly would NOS be a good idea to add horsepower to a 5sfe?

TreyMR2 · 04-23-2009, 12:14 AM

IMO no... nitros on a stock motor is a no no. Unless you don't plan on keeping that motor long.

fvillota · 04-23-2009, 12:22 AM

really?
some guy i go to school with has had a civic with a k20 in it (acura motor)
he has been using a 100 shot wet system for about 2 years now.
he does use it on week ends for the track, all he has on it its a wide band and standalone.

whats makes the acura special? or is there something that going bad and its just unnoticeable right now?

I think one of the big problems is that that kind of power is really addicting, and you'll want more and more, and you'll use it more often until kaboom.

Take a look at the price of doing a NOS system, it's not cheap, you might as well just spend a bit more money and swap in a 3sgte.

Also consider the cost of the nitrous itself, each time you squirt it you're burning a lot of money

MR2 Drifter · 04-23-2009, 03:35 AM

Well from everything I hear about the 5s, ide imagine that it can take a little bit of nos....maybe a 50 shot without messing anything up

but yea, to run a nos system is expensive, might as well go with the 3sgte and get the extra 60+ hp without having to push a button or switch

fvillota · 04-23-2009, 07:33 AM

yea i guess... i agree

Resurrected · 04-23-2009, 10:16 AM

and if N/A is your goal. get a BEAMS engine. 200 HP non-turbo

fvillota · 04-23-2009, 10:35 AM

true. but i'd be ****** bricks if i sprayed that. lol

what is a beams engine?

It's kinda like honda's v-tech. It's a 3sge engine, so it's the 3sgte minus the turbo. Makes just ovr 200 hp and it's a 2.0L N/A so pretty impressive.

It's a really good engine, but costs close to the same as a gen3 3sgte.

hey anyway to put vvt-i head on a 5s?

It would be interesting to find out.

It might not be worth it though. Because all the beams engines here in north america are imported so finding just the head to do it would be hard and expensive, also you'd have to do the ecu and wiring harness. But that extra .2 of a liter might give it just that much more grunt.

In a word no. It could be done but by the time you mess around getting galleries to line up then tune a computer to activate the vvti you could have built something better like slapping the 3sgte head on. Even if you could get the stock ecu to run it the rev limiter is too low to for it to be a true perfomance motor. Also there is compression and valve clearnces and a bunch of other head/valve related issues.

Besides if you build a motor and select the right cams you shouldn't need vvti it is just a way to get aggressive cams on tap. Tuning intake runner length and using a well adjusted cam can get the same results it is just BEAMS does that without having to think about it.

fvillota · 04-29-2009, 11:24 PM

cuz i would mind putting a vvt-i and then controlling it with a v-tec controller or my emanage.

Wouldnt the rod bolts fail as well at that RPM.

fvillota · 04-29-2009, 11:32 PM

of thats right.. well.. lol you slap on 3s bolts and the head! haha
just an idea. in no way do i have the funds to try this. you imagine?! a vvt-i 5s-fe?

328FTW · 04-29-2009, 11:55 PM

Getting a BEAMS with a cut loom and just going stand alone would probably be easier. The higher compression of the BEAMS would make up for the lack of capacity but puts the horsepower and torque up top more. 3sge with some higher lift cams and exhaust/intake to match would make good power for less than a BEAMS if you can get the cams done cheap or get good used ones and reshim for them.

The gen 2 3sge in my mkI hauls pretty good but I still want a turbo and am fabbing that up now, didn't take long for me to want more power in fact it took one race meet

I really like the idea on an n/a v6 though otherwise n/a is just not really worth it past ~200hp. Up to that mark it is a good road to take if you are not going to want anything after that. For 250+ go turbo. Inbetween is debatable with the beams motor.
