hey gurus, I have a problem with my 90 si hatch with a second gen B16a engine. first off, its currently running on a pr4 ecu, which is a non-vtec ecu from an ls integra. the previous owner wired it with a device that engages vtec at 3k rpm. My question is what will I need to do in order to do a proper wiring job on my car. I know the engine is obd1. what obd is my car? what wire harness will I need to get inorder to wire my engine up properly, and what ecu should I use? thanks.

Also, I have a problem with my breaks. I've already bleed them starting RR, RL, FR, FL but when I'm driving and step on the breaks, it goes to the floor. could it be the break booster? thanks in advance.

 

ur car is obd0 you will have to convert it to obd1 to start off get a different ecu and i think you should use ur harness and make it work for that motor

 

you have 2 options

Obd1 P30 or PR3
http://www.rywire.com to covert your harness or do it yourself. There are write-ups somewhere
use obd1 injectors, obd1 dizzy, 4 wire o2

or


Obd0
Pr3(obd0) or PWO
http://www.rywire.com get their vtec sub harness
use (2) 1 wire o2 sensor, obd0 Dizzy, obd0 injectors with resistor box

The injectors interchange you can use obd1 injectors without the resistor box in obd0 car, or run your obd0 injectors on a obd1 if you use the resistor box.

As far as your brakes go. it is probably you Master Cylinder (95% of the time). usually when the brake booster goes bad... your pedal is really stiff.

 

thanks for the advice guys, but which options would be best. i just want a reliable dd. thanks again.

Honestly obd1. Costs more lil more work, well worth it though.

best option above

or you can use a chipped p28 with a p30 stock base map

 

when i did my B16a2 into my 91 crx i used the si harness wired OBD1 injectors and dizzy into the harness bypassed the resistor box bought OBD0 to OBD1 jumper harnes and just wire the o2 senor, v-tec, and a knock sensor and run it on a p28 and it should run like a champ...thats how 2 of mine were done i have no c.e.l. and i run a chipped ecu

 

thanks for the link Ace and the advice guys

vtec

 

If you plan on getting the car tuned you dont even need the o2.

 

any suggestions as for the breaks? thanks
