Help, motor problems!
 

Just rebuilt my b18b with eagle rods, probe industries pistons, bored to 81.5mm, hastings rings...etc...etc.

Using the 450cc injectors on a stock map tuned for the 450's. The motor starts fine, cold idle around 1500 or so, no problems. Once the car warms up it idles funny and it you try to drive the car it has no power... absolutely no power to even move the car. You have to rev it to 2500 to get enough power to move the car, at the same time the throttle response is absolute ----, you have to slowly push the gas to get it to rev passed 2000, otherwise it boggs out and dies. When you're off the gas it eventually stalls.

I thought it was the turbo kit, so I took the whole kit off, put a header and intake on the motor and it does the same thing. Temperature on the temp gauge is reading normal, a bit under half (2000 civic dx hatch).

I was thinking the base timming is off, the car feels like it's running on 3 cylenders while when it's warm. My friend said one of my plug wires was arching when I tried to start it.



I'm gonna try a new set of wires and find a timming light, what do you guys think it is.. timming?

i had a problem just like that before and it was a plug wire, hopefully it's that simple for you also.

Re:Help, motor problems!
 

I had the same problem. turned out, a plug wire was loose at the dizzy side. start simple man. check your connections, and then go from there. plugs are in all the way etc.

Do your Basics, check all your ignition stuff, cap/rotor/plugs/wires etc etc. If those are ok check your timing, if it even looks off, just double check your cam timing before you adjusted it. If your off a tooth on the cams it will run real ------- shitty like that. Just do all your basic checks and let us know.

Hmmmmm.......I would try a different tune if none of the other stuff works. :-\

I had a customers corvette doing that. It was the coil pack. Maybe its the coil? ???

Re:Help, motor problems!
 

From what you guys are saying, it's probably ignition related. I'll give that a go. I picked up some jdm b16 plugs wires, but i'm not sure if they'll fit my b18b?

The timming was way off. I retimmed it, but I think one of the cams is off a tooth still because it spits and sputters and sounds like ass. Atleast the car will move now. I thought I smashed some valves, but the compression is 170 across the board, so I think i'm okay there (8.7:1 cr). Next i'm gonna take the 450's out and put the 240's back in for the break in period.

Check that cam timing, just take the valve cover off...

Re:Help, motor problems!
 

We put a snap-on timming light on it and it showed that it was idling at 3 degrees of timming where it should be about 16. I think one of my cams is off a tooth (10 degrees?) so i'm gonna retime it.. again.
