s13 blacktop sr runs rich

[eberle]

:ugh:freshly rebuilt sr that im getting tired of messing with and spending money on

specs for help:
cp SC 7326 pistons 87mm 9:1 compression bored and honed (used a mazworx
torque plate for bore) (150,150,150,150)
Tomei 1.2mm Headgasket
both head and block decked
BC valve springs and Ti retainers stock cams with rocker arm stoppers
BC 6209 rods
arp main studs
mazworx head studs
ACL Race bearings
freddy intake w/ circuit sports intake gasket
freddy oil pan
ISR water pump
Spec clutch and flywheel
Tomei Expreme exhaust manifold and turbo elbow
s14 T28 turbo
s14 Oil pickup tube
stock e5 ecu
walbro 255
z32 fuel filter
stock injectors

so after dropping the engine in the car starts and holds idle, runs very rich and smokes more than snoop dog

ran fine before rebuild and the only changes were the:
pistons
rods
intake
and valve springs

so i have no idea why its running so rich

tried swapping maf's with known good one and no change

any advise would help:ugh::picardfp:

Dead cylinder? And or tps and mafs.
Pull codes do a power balance test!

need tune for the change in compression...may be injector stuck open..

you shouldnt have an engine with forged pistons if you cant even figure out how to make a stock maf work with a stock ecu. Try a stock engine first.

that thing looks stupid rich in the video.
A faulty engine temp sensor can cause the ecu to think the engine never warms up keeping it running in the coldstart fuel maps making it run rich. (something like that)

also i think the nissan engines use 2 temp sensors, one for your dash gauge and one that actually feeds the ecu info
