i wanna buy this 1990 integra. the car has a JDM b16 sir2 motor but he sais that the vtec doesnt engage because he needs the ecu. what kind of ecu will i need what car did it come in or is there a easier way to fix this?

 

If the car is a '90, then you will need a obd 0 PR3 ECU. You will need to wire up Vtec pressure switch (2 wires), Vtec solenoid (1 wire), and the knock sensor (1 wire needs to be shielded and the braiding needs to be grounded near the ECU). Good luck!

 

can any anyone else help me and inform me more on this motor where it came from, ect.

 

So I'm assuming the car is still OBD-0?? If so you'll need a obd-0 pr3 or pwo ecu. Then you'll need to find the pinouts, and wire up the VTEC solenoid, VTEC pressure switch, and the Knock sensor. Also the pr3/pw0 will be looking for a second o2 sensor. So you'll either need to weld in an o2 bung and put in a second o2, or you will need to splice the wire for the second o2 into the primary, which is what I did. I know this all sounds hard, but it sounds harder than it is. You just have to run some wires.

What do you want to know, and how do you know it is from an SIR2? Take a pic and I will tell you what motor it is. If it is a OBD0 (1st gen) B16 it will be 160 hp to the crank. If it is a OBD1 JDM B16 then it will be 170 ttc. On the block does it say b16a, b16a3???

 

well like i said before the car is for sale and i want to buy it and the guy says its a jdm b16.... he is asking in the range of 1700, i dont whant to get in a car thats too hard for me to fix. look at the car here:http://hondamarketplace.com/zerothread?id=1425928 tell me what u guys think

 

1700? Buy it! It'll take like 200 bucks maximum to get the VTEC working. Those blades look hott on the DA, and I might just have to get some for mine!

 

bump for more advice before i buy it

 

Well he has no pics of the engine. I would get some first!
