can i use aftermarket heads with a stock intake,will there be any hp gains,im on a tight budget,but i need new heads and can se putting any money into the old e7s
Sure you can. But youll be putting a choke hold on that breathing from the new heads!! The stock intake blows! A new one is under 500 bucks, even cheaper on Ebay! Dont do it, youll be sorry!!
You can and you will!! I suggest at least gasket match the intake runners to the heads... usually the felpro 1250 gasket!! However as YOU Know.. untill you UPGRADE the intake and a bunch of othere things... you will see only A SMALL bump!!
Unless you have the heads already... get gears!! 3.73's / 4.11's !! Then Exhaust....! Then intake and be thinking of camshaft... Timing Chain.. injecters..T/B and you know what?? your car will be 4 xs as fast as it will be with just the heads!! and probably for the same COST!!
Dont be FOOLED into thinking the heads are the magic bullet!! Gears.. cam.. intake... all make the heads work like you would expect.... SOOOooo... Me?? refigure.. and get the small stuff for the cost of one BIG thing.. and look into heads as the last upgrade!! I wouldnt do heads untill I was in the high 11's on iron heads!! cool??
Probably. I know that was the reason I changed my heads. I still have the stock intake manifolds on there as well. The heads seem to have given it a lil more kick but I've never dynoed or raced with or without them so I can't say for sure. But it most definitely does work.
If it were me, I would get new heads instead of rebuilding your E7's. But like mentioned above you are not gonna see the true potential of a head swap without the other supporting mods.
Amen.......If you have your heart set on some nice Aluminum heads then get them. But you are not going to see much gains from them with the stock intake, TB and MAF in place
