Ok i was just wondering if you put a EBXR6 head , cam and the ECU into my EBI would it make a noticable differance?.aWhy i ask is cause i've been told it will and then i've been told i wont really notice any real power increase.I just dont want to waist money as i have just gotten my head re-done about 7months ago.

if your engine is fine then spend your money on the one you got now you'll get more bang for your buck. there will be slightly more power with the xr6 compared to std eb, nothing that will make you go WOW(you probably wont even notice it). what was done to your head?

I beg to differ a bit.. I noticed a pretty big difference just putting the XR6 cam into my ED engine..

(has more than just that now, but at the start that was all it had and it did make a decent difference)

but XR cam is not as good as some aftermarkets.. maybe go a wade instead... depends on what you would be paying for the stuff.

save your monmey on the head, spend it on a cam instead
