I am wondering why not many people supercharg a non-vtec Integra engine. One of my friends says that the Supercharger for the LS motor sucks because it's smaller than the GSR one. I don't doubt it's smaller, but why does it mean it's not good for the LS. If anyone has a supercharged LS, i would like to know how it performs and how it is in general.

 

Your friend is right. The JRSC kit for the LS does utilize a smaller blower than the kit for GSR/R/& Si and it's not really worth the price of admission. You could probably expect to see an LS w/ JRSC produce power similar to what a stock or near stock GSR would produce. I have seen charts of these but I cannot find one currently. It's not a real popular choice for the non vtec crowd due to it's low price/performance ratio. You'll drop a few grand into that kit and add 30WHP or so. A small to mid size turbo setup would be a far better option for the B18a/b crowd IMO.

 

It depends on what your goals are, if all you may want is 40+ HP, and a relativelty easy bolt on, for mainly street and auto-X use.

I think it's not a bad investment.

Also it known to be very reliable unit, and it's emission friendly.

Although if you have an ODB2 LS, I would recommend the Greddy Turbo.

 

Not to pound it into the ground, but I seriously doubt you'll get 40+WHP out of that blower...Eaton M45 if memory serves. Least w/o spending a decent chunk of change over and above the kit. There's a reason that kit isn't very popular. I like the JRSC BTW...just not that small blower.

A SCed LS would be about the same power as a GSR STOCK motor... you'd get looked down upon by everyone since you'd be FI and considered slow. Atleast I would look down upon a basic JRSC B18B setup. If its a B18B, go turbo not SC.

 

I'm even suprised Jackson Racing actually made a supercharger for the B18A/B... and for the power it gives out, eh.. its not <U> that </U> bad

 

I wouldn't personally care who looked down on me in this hypothetical...but $1k/10WHP is just not so good...rather similar to NA actually...LOL.

 

yeah could spend the same amount on turbo kit and put out well over 200hp...

 

I'll agree that the M45 included in the jackson kit is weak, but the upgrade to M62 is not terribly difficult to do. The M62 (GSR) blower, combined with an ITR or b16 manifold bolted to the b18b will put out some very good hp numbers, and a torque curve flatter than Ohio.

 

True that...though it's extra hassle and probably extra $$$. Not sure how you're gonna get an ITR or b16 manifold in there like you said...but hey with a big enough hammer...it'll fit I suppose.

 

theres like 2 bolts that are different on the intake runners themselves and the coolant lines are different. its actually fairly easy to put the kit meant for a type r onto an ls/b20 engine

You can also probably find someone who has done the conversion already as there are a few of these floating around the market.

I love the jrsc.
It may run out of stink on the 1320, but it never leaves me laggin on the autoX, and it's only been beat in 1 stoplight drag, against a 67 Chevelle with a big block.

Check out LHT performance. They're awesome fabricators and the first to release an intercooler kit for the jrsc. They could probably do the conversion for you, all you need is the ITR/b16 jrsc kit (or a GSR kit with an ITR manifold).

Yup !!! That's what I thought.

 

I suppose I'm the only one standing up for the LS JRSC.

My arguments about the HP gains are that for auto-X and street use the JRSC would have a nice flat mid range power band. Minus a small turbo (t25), the only way to get that kind of power band would be sticking n/a.

If being even pessimistic, 30+ HP from the JRSC is still better than what you could possibly get out of an n/a LS, in a resonable budget.

Also I have found the price of the JRSC around the range of $2400 - $2800.

Without going into a flame war, the JRSC still has it's benfits.

 

Sure it has it's benefits, but that money is much better spent on a turbo when dealing with an LS IMO...and apparently alot of others' as well.

 

i think supercharged hondas should be outlawed........ive only seen 1 that came close to the power output of my car, and that was a supercharged type r making 237, the rest of them ive seen and heard of havent made it past 200.......

 

Larry used to have a section on his board that had the itr blower conversion to fit an ls.
