OK guys I got my RB25 S14 running today, and well I need some help working out the bugs.
Mods:
Stock S1 RB25
Freddy Intake
Stock TB
Yamamoto Tuned ECU (came with the motor set)
Walbro 255
3" Turbo Elbow
CX Racing Front Mount
Thats basically it that is aftermarket
On the first start up everything seemed great. Idled great, and everything was going good. Took it for a drive across the street to fill up with fuel, and drove it back to the house. Went out again just for a drive, and noticed that the car doesnt like boost (WTF).
On the first drive, I was able to get around but the car would start to studder and jolt right when it got into boost, and it'd get past the studdering, and pull like normal, but felt very sluggish. The car also hesitates if you give the throttle a quick jab, almost tripping on itself. THe problem got worse the more I drove it.
Came back, fixed a coolant leak, did some other tweaks, and went out for another drive. Right away, even a little bit of gas, and it will studder. And even just 1-2 PSI makes the car studder real bad. Headed back home, and going around a corner, about 10mph, the car started to studder, and just died. After that it would just crank, but smell of fuel really bad. Checked for leaks, none. Just cranks.
So my question is, with the atmospheric blow off (HKS SSQV), on a stock MAF, with a Yamamoto tuned ECU, and a Walbro, is the car just drowning itself in fuel, and just finally fouled out the plugs? I havent taken them out yet, its too late at night now, Ill check tomorrow.
My friends are telling me with the tuned ECU and Walbro its just running way to rich.
Also another thing, without the Walbro, the car wud rev fine, no problems, but never got around to driving it on a stock S14 pump.
Also car is on stock boost.
Any body got any advice? Pretty sure at this point its not a boost leak, otherwise it'd still start, and not stink of fuel.
