I am a 16 year old that recently just bought a 1994 g20, I've been doing some research on it. It says it has 276,000 miles, and it has a naturally aspirated red top SR20, from what i came up with this car shouldnt have a red top? Is it the original engine? Is the engine higher compression? The only similar car i could find is this- http://www.son240sx.org/showthread....G20-SR20DE-Red-Top-RARE-5-speed-Leather-CHEAP
The red tip means type r!
No but it does have a either jdm are ukdm valve cover.
Their are lowport high compression 10/1 comp engines and they would have sodium filled exhaust valves and oil squirters for the pistons. It's possible you have one of them are someone changed the valve cover.
I think the high comp lowport did have egr on it already to
If i had to guess i would say that is a jdm engine swapped into the car. the reason i say that is that it appears to be a highport head with a lowport intake manifold. i might be missing it but i do not see an egr which is why i am assuming jdm sr20 and not a usdm replacement. usdm would have an egr. i really doubt its a diy valve cover paint since the plugwire valley is black and the nissan name vs the oem infiniti name.
this is a picture of my p10 with a jdm highport det before i removed the engine. mine is a highport with a highport intake mani. no egr present on my engine.
