Is it possible? BTW I still wanna use 93 octane gas. I have only some vague idea of what I should do, but it would be very helpful if guys can give a more detailed description on what I should do, buy. Also any estimation of cost are welcome
Thanx

well that depends. do you want 250 at the wheels or at the crank? it would be easier to get 250 at the crank. I think you would have to lower the compression, maybe water injection or methanol injection good flowing header, cat and cat-back. oh, and tuning. tuning will probably be a major factor in getting 250 hp from a sc'ed b17. good luck!!

 

lowering compression will make u LOSE power. 250 even crank HP from a JRSC is highly unlikely, even with all the tricks.

 

dont steal **** first off. and if you want power...i suggest you get something other than that jackson racing charger.

 

hehe, sorry lower the compression while raising the boost. It should make more power while still running pump gas

 

"steal"
i know of one gsr that put down 220hp or so to the wheel.

 

for real power ditch the b17 and supercharger. b18c1 and drag3 kit will answer all.

 

There is a member on g2ic.com that just finished his Vortech setup on his B17A. He dynoed and it hit somewhere in the 270s whp and high 180s wtq I believe. That's with the aftercooler and a hytech 4-2-1.

 

slightly raise compression, get an intake cam, fuel, tune, tune, tune, tune.

 

vortech sucks **** ahha...it makes good whp but only numbers, cuz it doens't get full boost till redline. 250 at the crank is very possibly out of a gsr engine..at least a b18c1...at the wheels is...kinda unlikely but i'm sure it's possible...IB had a b18c5 w lowered to 10 compression w 17 psi boost on a JRSC and 80 shot NOS...450+ HP...the wheels spun on the dyno...so numbers are easily possible, but whether you can drive around townl ike that without any fuel problems is well...a different story.

 

If not a Jackson SC then what's the best way? If turbo, what's my options? Wouldn't a turbo B17A very complicated to build? there's also a lots of custom work when I use a turbo right?

My main goal is to have a drivable car with 250hp to the wheels. I'm not looking to drag race with this car. I just want something that'll not get my *** kicked everytime on the street. any suggestions?


A side question, how much can I squeeze out of a all-motor b17 that uses CTR pistons?

considering there are people who have put ICs on their JRSC, 250 at the wheels is not unrealistic on pump gas.

 

When you say IC do you mean the intercooler from Jackson?

 

custom-made intercolers

"STEAL"

anyways, it will be tough to get all that from a JRSC, or at least a lot tougher than from a good turbo setup.
But if you insist, a nice engine rebuild, and whatever PSI you can crank that supercharger up to.
Everything else being equal, 10 psi from a turbo will kick 10 psi from a JRSC's ***

 

Well, I know how much more a turbo can deliver when compared to the JRSC. However a turbo wouldn't be able to deliver power at low rpm right? I would have to at least rev to 3000+ rpm b'4 I can feel the turbo right? Since I'll be doing mostly city street driving, I stay mostly in the 2500-4500 rpms. I usually only get above 4500 on occasional straight roads. Thus I need the boost to kick in at low rpm and hence my choice for the JRSC. Is there any way I can get the same feel/delivery from a turbo at low rpm??

If not 250hp, what the realistic hp I can squeeze from this setup?

A JRSC does not fit on a 2nd generation integra. As for the vortech setup, that thing kicks ***

 

vortech doesn't really kick *** when you consider that it has the parasitic drag of a SC, and the "spool up" of a turbo, meaning it is not instantanious.

so unless i am mistaken, in the lower RPMs until the VSC actually starts making boost, it is actually a drag on your system not doing anything, but once you get it spooled, it is a haul *** system.

I know that the greddy 5lb turbo kit is supposed to be a really small quick spool turbo (making it as close to instantanious power as you can expect from a turbo), but don't expect to get much more than 5lbs of boost cause it is a small turbo and the efficiency of it at higher boost levels will be way down.

anyway, it all depends on what you want, any way you choose to go there will be lots of heart aches, there are no rosy paths to follow with aftermarket forced induction.

 

does anyone know where /how it shows u to make a custom IC for ur JRSC? tha'td be tight...hehe.

 

What I really want is a way to get more instantanious power delivery and I wanna get as close to 250 hp to the wheels as possible.

Just a thought:
If the greddy turbo can spool quickly, but is limited to about 5lbs. Would a twin greddy turbo work? What would the cost be like??

 

"instantanious power"


Really hard to get out of a 4 banger in general. One thing you need to do is drive a turbo car, people that complain about lag usually dont have a turbo car and just kinda preach "what they have heard"...Unless your turbo is WAY to big lag is never really an issue, just downshift and all your boost is there. If you are really really worried about lag then just make a custom turbo set up using a HKS ballistic turbo, the gt25R Ball bearing will get you full boost under 2500 rpm's on most 4 cyls.

The Greddy 18G turbo kit is a really nice setup, I Installed one on a GSR a little while ago (car got stolen 3 days after) the Spool up time was very nice and he had STOCK exhuast.

Drag and Fmax both use t3/t4 turbo's and can be made custom so usually you can get a good size turbo just talk with them...Jrsc Is fun for about 5 minutes, then you get beat by some all motor guys and kick yourself.

 

there is a guy on http://www.G2IC.com that has that exact setup already. He has dyno pics and all.

Here is the forum address.

if anyone is too lazy......

I was pretty impressed, this was my best HP/TQ run, I had a better run by moving VTEC from 4800 to 4100 but the belt started slipping from some leaking Powersteering fluid after 6300 rpm and the max power was only 249 @6300RPM.

The Civic SI 8psi aftercooled kit is moddable to fit on a gen2 GSR.

Other mods I had with the kit:

CRV crank pulley (good for +3psi)
Hi-tech 4-2-1 headers
68mm Holley TB
Skunk2 IM
550cc injectors
Supra TT fuel pump
Hondata Stage 4B +emu
test pipe
RSR catback

My car sounds quiet at idle except for a whistle from the supercharger, after about 3000 you can hear the BOV if you let off the gas. I need some fuel tuneing and I'll be done. Needless to say I am pretty happy with my results.

 

what's the full boost for g25R?

 

all i got to say is if you buy stolen ****. ill personal beat the crap outa you.

 

"the gt25R Ball bearing will get you full boost under 2500 rpm's on most 4 cyls"


oops My bad I didnt mean Full boost by 2500 Rpm's that would be INSANE. The gt25R will start to Spool at about 2500 Rpm's and looking at full boost by 3200 Rpm's. I had this turbo on my Mr2 and made 290 Whp at 14 PSI, so thats very low boost with alot of power

I miss my mr2
