Is there common ways to mod. the northstar engine? Are aftermarket kits like, PCM, Mufflers, High Flow cats, Injectors, Air Mass flow sensors, and so on. Pretty much all bolt on mods. I allready have the K&N Drop in filter... are there any FIPK's for the Eldorado? Any experience or info would be greatly appreciated.
My caddy seems to have both a MAF sensor as well as a MAP sensor. I have an Autotap diagnostic tool which lets me monitor all the sensors using my laptop. Well I can get a signal from botj the MAP sensor telling me the pressure in the manifold and the MAF sensor telling me how much air is flowing through it. This is common among many high end engines. I know Audi does it on it's V8s too.
As for mods...I think we are all in search. RSM racing has some. I also found an intake advertized by Lund cadillac. I sent them an email and they told me to call. I just haven't gotten a chance to call them. Cadillac hotrod fabricators has some stuff but it's mostly meant for use in northstars that are used in hotrods...often with carbs, or sometimes custom injection systems. They generally aren't designed to be compatible with the factory engine management system. Corsa has an aftermarket cat-back exhaust. I may have to get that. What I would like to see is a decent intake and exhaust, (the above mentioned ones may be decent) coupled with a head and cam package, and a chip to adjust the fueling. I think we could have a healthy four hundred horsepower if the head and cam package is well designed. I'd also like to find lower/stiffer springs, and thicker swaybars for my DTS. I'm not sure how the load leveling system would work with that though.
