single cam injectors in a gsr
hey so what r the bad sides to using single cam injectors in a gsr, untuned using a gsr ecu. i know it will b lean cuz they're about 30 cc smaller, my spark plugs are gettting white pretty fast. willl it hurt a motor that's being broken in?

^^ incorrect.. check this site.http://www.phearable.net/tech/stockinjectorsizes.html and also i would not recommend getting diff size injectors and running untuned thats not good for your motor man.

Re: single cam injectors in a gsr
here's an old school site that i always used for injector info. i worked with this guy on some of them back in the day, using info from a few sources including ACCEL.

to the OP; you should really have a baseline tune esp with a fresh engine. is the build out of factory spec in terms of compression, cams, etc? you don't want to dilute the oil, wash the cyl walls down during break-in, etc.
some people take a fresh engine and break it in on the dynapack, then tune it. i remember this dude nate tasukon, who now works for motec, used to build engines and take them immediately to do final tunes, flogging the things. i never really felt good about that ; )

Re: single cam injectors in a gsr
well they are from the d15b8 so i've been running 55cc too low. my compession is at 185 in number 1 and 80 in the rest. i think the lean mixture had a lot to do with it.

Re: single cam injectors in a gsr
no, he means the actual head of the valve not seating properly in the valve seat, thereby allowing much compression into the intake or exhaust.
a leakdown test is the way to go here.

Re: single cam injectors in a gsr
i did put new rings in, y the hell would i call it a rebuild and not do that. but no i did not check the valve seats cuz i didn't wanna pull the valves out. i did a leak down test and the cylinders with low compression did not hold pressure becuz the rings did not seal right.
the reason i want to change out the rings again becuz they obviously didn't seat right. so when im gunna take the head off and have the valve seats checked

Re: single cam injectors in a gsr
im doing good. just working on my car. rear tire popped on the freeway, spun out, hit a pick up and ended on the side of the road. THANKFULLY!
OP, take your head to a shop so they can fix it. and while your at it, if you have funds also, get a 3 angle valve job and a port and polish
