I have a 97 nissan 200sx se-r I built I'll include the build but cylinders 3&4 have a dead miss cylinder 3 starts to come in around 3500rpm cylinder 4 doesn't come in at all. I replaced the distributor plugs and wires i checked the spark and its blue. I had the injectors flow tested and did a compression test across all 4 cylinders which all were within 5 psi of each other. What else would cause this dead miss?
The build:
The cylinder head was disassembled, cleaned, inspected, and reassembled with the following components:
-competition 3 angle valve job with 0.040" valve seats
-Valve job performed on a Serdi machine
-cylinder head ported and flow tested on a SuperFlow 600 flow bench using Audie Technology digital interface
-exhaust valve guides replaced with manganese bronze and honed to spec
-all 16 valves reground using Kwikway valve grinding machine
-cylinder head deck milled to ensure flatness(0.010" deckmill)
-valve shims ground to fit Tomei solid lifters
-fwd sr20de valve cover powder-coated black with breather baffles removed and rear breather tube plugged off
-HKS adjustable camshaft gears
-Greddy rocker arm stoppers
-Tomei solid lifter
-Peak Performance race spec valve springs
-oem valve stem seals
-HKS 272 step 3 intake camshaft(228 degrees at 0.050" lift, 12.6mm lift)
-Nismo 280 exhaust camshaft(224 degrees at 0.050" lift, 12.6mm lift), this is an extremely rare camshaft. it was briefly made and I had to buy it directly from a distributor in Japan.
