I saw on the JR website that the JR Supercharger will put 160 whp with I/H/E for about $3000 + install. I am just thinking that wouldn't it also be possible to produce that kind of power going all motor for the same amount of money? (Not including I/H/E) So what kind of mods am I looking at to produce that power? Cams, new valves and ECU? 'Cause I would definitely prefer going all motor than supercharging. Also, what's the highest I could safely rev my B18B up to with valve springs. And don't tell me about Turbos. I have had just enough bad experiences with them on my last Celica.

 

160whp for 3000 just isn't worth it man. i would go for a turbo; then you'll make respectable power.

consider: GS-R with bolt ons = 160whp

 

Ah, I like all motor... that sweet sound of F1 engines... Anyone? How would I go about to get 160 whp with all motor on B18B engine?

 

all motor

header,cat,exhaust,intake
pistons,rods,2 layerheadgasket
cams,fpr
cam gears, vafc
valvesprings, retainers

....more hp.....all motor is less damadgeing to your engine
its also more respectable......if you compete at the track you wont have to race in Power adder class...

 

yeah, but a GS-R with bolt-ons is not going to have as strong of a powercurve as a LS with JRSC.

6psi through out the RPM range is going to end up faster than an all motor engine that gets most of its power from 6000+

Second, that dyno that Jackson Racing put up was on an integra that had far from a quality supercharger setup. A header with short primaries would have much better numbers.

This is shadowdawn under a friends name cause I'm at his house and it won't log out

Anyway this is the reason I DID NOT GET a JRSC for my ls (automatic 99 LS)... I got turbo instead, and my car hauls some *** and has serious torque now from 3grand and just multiplies till 7grand......

All motor isen't gonna net you as much power as a $3000 turbo kit will, just my opinion. Don't have any numbers to give you, sorry.

 

i'd spend the money on a turbo kit.

 

Like the man said :D

 

yea...u'd wanna turbo an LS....even tho...w the 9:1 compression the LS has...u can run 9 psi JRSC and get about 186 whp (96 integraRS) has one, thats respectable power...but turbo is even better on an LS...on a GSR tho...the jrsc is prety good...of course thats a bit biased coming from a charged gsr owner

 

It depends on what you want out of your car/engine

a turbo LS is not always better than a supercharged LS

In autox/track, the spool time for a turbo can be very damaging to your times compaired to the instant boost of a JRSC.

hey do you know you can put a Vortech Supercharger on a 2gen gsr? i didn't know it was possible.

 

Yeah, but the vortech supercharger kinda sucks for high reving imports
Might as well get a turbo kit.

 

all motor less damageing??? I guess your into "mild tuneing"

more respectalbe? ****..... respect is beating some big nasty V8 no matter what it takes...

300whp all motor = $$$$$ x2
300whp turbo = $$$$$

 

yup

I'd spend the money on a turbo setup, only if you want serious power. However, if you can be pleased with about 200whp, go with the jrsc. It's a blast to drive, but unfortunately you'll be topping out at about 200 because of blower inneffeciency.

If you want to get huge power, go turbo. The fact that you can intercool a turbo makes it a tough mod to beat for big power setups.

Of course with 200whp and your stock peg-leg diff, you'll be getting serious torque steer.


and GSRwBOOST is correct. All-motor is definately not the cheap or easy way to get power.

 

But its the sleeper way to get power. No blow-off, no whine, just a cool sounding beast.

 

LS Turbo

 

160 thats all? fron a jrsc. i got 169 whp on 3 pds off my DRAG kit. yet anyoer reason why i didnt go sc

 

These are my reasons for going all motor than turbo:

1. Build to the same spec, an all motor is always more reliable than turbo.
2. If you do track racing, than you truly understand the term: TURBO LAG
3. All motor power is way more linear than turbo.
4. Not as long warm-up (below 30 C) or cool-down in all motor than turbo.
5. Anyone can build an engine and slap on a turbo and run 12 seconds with full interior. Try that with all motor.
6. That unmuffled distinctive mechanical sound. (Try comparing the sound of F1 cars (all motor) with CART cars (turbo)
7. All motor is racing in purist form. That's why F1 banned turbo. (Turbo is like using steriods to build your muscle.)
8. Quote from a mechanical engineer "Only poorly designed and weak engines need turbos. A properly engineered all motor engine can match the reliablity and output of that of turbo. It's all in the engineering." (F1 engines vs CART engines)
9. Running the same horsepower, an all motor engine is lighter than that of a turbo engine.
10. An all motor engine can be build in steps (less strain on finance) instead of a lump sum money.

Sorry, I am not trying to knock on you turbo owners. I think turbos are great if you are trying to achieve a fast quarter mile car with less money, but I am looking for something different here.

So anyone can give me some tips on building an all motor engine. Can I achieve 160whp without building my bottom end?

 

something diffrent. i dont think theres anything diffrent in the honda game anymore, with some exceptions. 160 all motor stock block..... i dunno. one thing to look at is a si or type r tranny. the ls tranny isnt going to cut it all motor

 

how about ls/vtec 190hp at the wheels

 

I don't mean something different as in different than everybody else, but different as in not drag racing. I am more into road courses and mountain road as in Initial D (True Japanese Street Racing).

As for different, if I had money, how would an integra with a mid-mounted supercharged prelude engine sound. Have the engine sit right under the hatch just like the Modena and convert it to rear wheel drive. That had be sweet...

 

i would either go ls/vtec or boost or actually both ls/vtec turbo

 

All motor can't be reliable bumpin that compression and revin higher all day long can't be that reliable but yet its more reliable than boostin tho. But either way boost or no boost it still put strains on the motor. I'd still say go with turbo more power hehe

 

yea man, NA reliability goes bye bye when u get cams with big *** lobes, high compression on pump gas...no cars are reliable when u heavily mod them (at least not as reliable as in stock form)...as for around the track, a small turbo will have very little lag, and perform real well, FI also gives more torque than NA on hondas, cuz with NA the powerband is only up top, giving you no bottom end, which takes away a lot of daily driving fun and practicality. SC is a good idea, it's just limited esp on an LS, but u can easily make about 190 whp with a good 9 psi JRSC setup and some fuel tuning. NA is NOT cheaper, it mite not be a lump sum, but u can just save up and spend less on a turbo set up to go faster, i dont think it matters how u go unless u plan to race in a certain division.
As for F1, man ur engine will never be an F1 car or anything near it, so there's no point in comparing those to CART cars or wat not, so who cares what they say or ban. You drive your car everyday i assume, so paying less to go faster is basically smarter i'd say, make ur decision from there.

 

good points LOwrestling

Also keep in mind, that peak HP is not the be all of end all. Just like you said the NA engine will only have power in the peak RPM's, a turbo kit is more peaking than a JRSC.

So in the same sense that a turbo kit will have a stronger power band than an NA, a JRSC will have a stronger powerband than a turbokit.
