obd2 gsr/jrsc questions

hey guys, i was wondering your take on an obd2 gsr with a jrsc.
how much bosst from a jrsc could a stock b18c handle? whats the best option as far as tuning aside from obd1 ecu swap? would a 2.5" exhaust be good enough for the amount of power a stock b18c could make with a jrsc? and what header would you suggest for this? a standard 4-1, a kamikazee style 4-1 or 4-2-1? also, short ram intake, icebox style, or cai?

I can't think of any users running super chargers here, and because I have a lack of knowledge in the SC department, i'll just give you a link I found and hope someone else can chime in to help.

The most noticeable thing I have found from several websites about the JRSC is this.
JRSC dont work with a DA unless extensive/custom modification is made to the master cylinder & lines to give more room for the pulleys.

But you didn't really give much information on the car, i'm not sure if the third gens are much different regarding to master cylinder placement.

Something to read.

If it's anything like a turbo, I would suggest 3" exhaust. The headers you should just go with the best flowing, I don't have any experience with the listed headers there. Just try to find a header that flows well and you will be fine. I'm just going to assume the super charger would cover the intake portion of this, am I wrong? The ECU i'm pretty sure can be tuned with a piggyback type system to go with the OBD2 ECU's, might be easier just to do an OBD1 swap.

However I can't say much about the power the JRSC can put out, so i'm not going to say anything about that.

i was just thinking stock gsr block/tranny with itr head (so i can buy a new itr kit instead of finding a used gsr kit) with 3" sri, ported jrsc w lht aftercooler, kamikazee header, highflow 2.5" cat and 2.5" mandrel catback.

obd1 conversion with p28 tuned on hondata/crome? or is there another good option to tune with? (no afc or JR tuning hacks)

if i have to go obd1 p28, what whould i do when time for inspection? in NC theres no sniffer/tailpipe test, but they do hook the obd2 computer up. how can i get past this with a chipped obd1 ecu? or would i HAVE to remove the sc belt and put the stock obd2 ecu back in?

The ONLY reason to put a supercharger on you car is if you are a HARDCRE circuit racer, if you want power go turbo. A turbo setup is cheaper, gives you waaaaay more power, and turbos get better gas mileage :thumbs up.

then what turbo KIT (do not want to piece one together again) would you suggest that has everything i need to reach atleast 250whp and retains ac/ps? i dont want a RACE car, and i want to keep ac and ps, and buy everything i need (other than ecu/tune) in a kit. also, how would i go about inspections if i run a chipped p28 and obd1 conversion?

whats your budget?
id recommend a Peakboost kit.

The only benefit SC's have over turbo's is a smooth power band because its belt driven and spools instantly, so you don't get power spikes in the middle of turns.

Supercharged


Turbocharged



see how the turbo power band jumps up? its not a problem at all for racing on the street or at a drag strip and really doesn't effect much if you go to the circuit for fun, but if you want that best lap time then a SC would be optimal, but very rarely is that the case.

my bestfrend has a Em1 Si with a fully built block and a full Vortech SC kit, and it only makes 251 to the wheels, its fun and pretty quick but you cant turn the boost up on it, so that s the max power hes gonna make unless he fully builds his head or gets a different SC

i was just hoping to get 250whp from a jrsc with correct supporting mods for a DD. BUT, im starting to see not too many b18c's hitting 250whp with more work than i was planning.

so peakboost kit can get me to 250whp on stock block, keeping ac and ps?

what do i have to do as far as tuning / inspections go? its an obd2 gsr, and will not go with an afc or any hacks like that. my only option a chipped obd1 ecu, and swap to obd2 ecu for inspections and hope i dont destroy my engine on an untuned obd2 ecu for an hour or two?>

yeah like i said before, a b16 with a fully built block, a great tune on hondata, and a maxed out Vortech SC (10psi) makes 251 to the wheels, hes put around 30-40k including suspension. Don't get me wrong, it's a BEAST at the track, but on the street its not much.

if you have the cash id get this
http://www.prostreetonline.com/x/peakboost-b-series-turbo-kit.asp
then get some precision injectors >700cc
Walboro fuel pump
Hondata ecu
and a tune and you'll be good to go.

if you get it installed right you should pass emissions, if you don't you can just find a "hookup".
and its ok to limp it to a tune, just make sure you have a boost gauge so you can watch it and make sure you don't get in boost until its tuned just to be safe.

im just worried about when inspection comes and they have to plug into the obd2 plug under the dash. so if i installed it, got a chipped ecu, got it dyno tuned, i could put the stock obd2 ecu back in and drive it (out of boost) to the inspector and be PERFECTLY FINE driving less than an hour UNTUNED to get to and from the inspection, then swap the chipped p28 back in?

a hondata ecu, is a stock ecu, its just socketed and chipped, you can clear all for the codes your self so when they do hook it up they wont see anything wrong

what state do you live in? if your in cali then you can throw all of this out of the window and go buy a carb legal intake LOL

I was looking at Peakboost kits myself and ran across that, seems they went bankrupt in Oct and ripped a lot of people off in the process.

i know that hondata is just a stock ecu, chipped so it can be tuned. i am talking about for emmisions. cuz i'd have to convert to obd1 to run crome or hondata or anything, right? i'd have to put the stock obd2 ecu back in for inspection right?

no, the hondata ecu will be tuned...
if you put the stock ecu in it it would run like shit and fail
if you get it tuned to pass it will pass
but a lot of states are pretty lenient (compared to CA) and i just get local "hookups"
