Ok i have a 99 gsr, duh obd-2 , iam really confused about switching the intake manifold

I was gonna get the jdmshit / itr styled intake manifold soon but i cant figure out what the hell everyone does with the problem with the runners working, i mean yea i can convert to obd-1 but will that switch everything and make it work for me? with no problems?

i heard if i switch to the obd-1 with a chipped p28 itll make the car run like crap up top, so what should i do?

is it possible to contact kenji and have him make a chiped p28 that will work and trick the motor into thinking it has runners ?

any help, links, or info will be appreciated

 

you could hook it up to an rpm activated switch and run a chipped ECU for the maps

haha something non ghetto haha

iam just wondering what the hell people who allready have that manifold are doing

 

use a GSR ecu to open up the IAB on the gsr manifold. obd1 GSR's and OBD2 gsr's i think uses different polarities to open up the IAB. a cheap solution for u is to zip tie the IAB open. this will give u good top end but the bottom end power will suffer

 

i wasnt gonna use an obd-1 gsr ecy because its the same as the obd-2 one just the emission difference, the obd-2 manifold is the same, and works the same as the obd-1 ...so that would be pointless wouldnt it?


i seriously heard that u could just get obd-1 conversion and chip the ecu and it will get rid of the stupid runners kicking in at 6k to where its just vtec at 5,400 and full power from then on to 8200

 

whats so ghetto about using an rpm switch? thats all the ECU is doing when it controls the butterflies is complete a circuit at a designated rpm.

 

it just reminded me of push button vtec......

dont get all offended this thread is meant to educate because there is a way to do it how i described but i just wanna make sure before i do it if i do

 

all you have to do is put your manifold on, as far as you ecu concernerd you can run an chipped p28 wich is a good ecu to run also you wouldnt have to worry bout an knock sensor, you could also run a p30 stock or chipped you can also use hondata on either one of them and actually tune your car for your setup (prefered)
all this providing you convert to obd 1

 

can anyone confirm this? because i heard if u use a chip p28 the car is just gonna run like **** up top

 

so if i run a itr styled manifold on the on ethe factory ecu what will it run like

 

i heard that the motor expects the runners to be there and so when they arnt it just wont accelerate if u are in a gear trying to go past 6k but i dunno

i guess no one is buying the jdmshit manifolds and testing it out

14.6@95 with a p28 ecu running the mugen program
blox intake manifold
hondata im gasket
exedy stock replacement clutch
usdm type-r pistons ~10:8 c/r
stock ls exhaust
stock gsr header
this is in a 2600lb da integra
b18c1 motor

my car runs fine with this ecu, a bit rich but besides that it runs good. 5500 vtec x-over is high for the gsr cams but it still pulls great, my bottome end is not the best because of the manifold and low vtec x-over point but it is still hitting good times.

 

chipped p28 with Skunk2 intake manny no problems

 

cool guess i might try it then

thanks for the help guys, hopefully if anyone has this question again they refer to this thread uz i couldnt find **** about it
