   Im not a 100% sure when it comes down to stuff with engines but would a rallye head put on my vtr make any diferance with the ecu to as it has a high lift cam ect?? my m8 is on buying a rallye of my other m8 and hes throwin the engine to make room for a GTI and said i can have it for nothing
   would this be worth doing?? and what cange in proformance would i be lookin at?
   Cheers everyone

   I've heard of it being done, but i dont remember if you have to get ecu remapped or not. you will be looking at rallye bhp 100+.

   if its different cam in the rallye head then surley u have to? ecu in vtr will be fueling vtrness. wont be mapped to fuel those valves lifting a lil higher etc. or i could be completly wrong. lol

   no i ment i would use the ecu thats on the rallye that im geetin the head off that would be okay then wouldnt it? as all a rallye is, is a vtr but with the diff cam nd 1 or 2 other bits?

   i didnt think you would get an advantage from the rallye head, just from what ive seen others post on here about it

   i think the rally head is ported and polised and has a uprated cam but im not to shor the rally inlet is better as well it shuld run on vtr ecu but you wont get much gane from it best get it remaped. the rally ecu will have to unlocked but i dont think it will werk any way the wiring lome would be slitly difrent.

   its got a more lairy cam and the inlet manifold is superior. I've never looked into the mod but you must double check that the head volume is similar/same so you dont lower the compression ratio.
