I love GM fuel injection systems. I owned several cars with the TPI system and LT1 f-bodies. My daily driver is a 1990 IROC-Z with a slightly built factory 5.7L. I'm on thirdgen.org with the same screen name as here. I bought the Buick already complete with everything hooked up. This weekend I need to take a picture of the cam sensor and send it to you. You might be able to give me some insight on it. I would like to hook it up as sequential injected, it should give me slightly more HP and better gas mileage. I will be driving this car weekly when it's finished,I'm not a trailer queen kind of guy. I rebuilt my current 240Z when I lived in Tucson back in 2003, after the build we couldn't get it thru emissions. Too high compression, 10.6 to 1, and to big of cam, don't no the specs but it is a factory stamped Nissan cam out of a Bre car (sounded like a cammed small block). I had to put the factory cam back in so it would pass. I now live in Virginia where there is no emissions just safety inspections so anything is possible. The cam, lash pads and rockers are still sitting in a box in my garage, one day I will use it.... When do you expect to get your Z on the road?
