GSi has Round ports like Sri.

lol.

you could do a Cylinder Head Top Trumps to compliment the Novaload ones.

stats could be

# of Valves
Inlet shape
compression ratio
valve diameter
etc.

lol.

in that case then is there any difference between the sri and gsi heads ??

p.s. i am only going by what i have read on various websites

no they are the same head, a lot of the parts that are on the gsi are shared with the sri. the gsi may have larger valves in but i am not sure about that

and obviously if you put a GSI/GTE head on an sri the compression ratio would drop.

so, ur all saying that, if i put my T40's on a SRi head then it'll give me MORE power? :twisted:

and, also add the NOS kit demon tweeks stock for carb'd motor's? :D

doesnt the sri head have all the hole's etc for the injectors tho? if so, how do i block 'em up?

you mean the inlet holes? If you block them up mate your car won't run at all. Thats where your T40 manifold bolt onto.

holes for the injectors are on the inlet manifold. you get a new maniflod with the 40's anyway so dont need to worry about the injector holes. go on, indulge in some direct port noz :D stady 25-50bhp shot should be ok with a controller 8)

the gsi and sri heads are listed as different part numbers so they may have a different clearnace volume too

and the injector holes are on hte inlet manifold ;)
