Converting Ecotec V6 to blown L67. Are the fuel rails and injectors (location, design etc) on the L67 different to the NA version ?
Trying to eliminate time wastage by asking before goin in head strong...
Cheers for any suggestions

Yes far different, the fuel rail runs back and forth over the blower.

i think the fuel lines coming from the tank are the same. but the injecters are in the heads on an L67 and not im the manifold like the ecotec

Ok, um wtf.. do the L67 heads have direct injection or something? we have the adaptor plate manifold thing for the S/c, all rails etc but nowhere for injectors to go..

Nope, the injectors are definitely in the valley section of the L67 intake manifold. Definitely does not have direct injection(since it wasnt invented yet lol)

Should be in the manifold runners, just before the ports :thumbsup:

My thoughts exactly... SIDI recent innovation on Holden's V6...
I can see clearly where they are located on NA manifold, blatently obvious

I cant see any holes for injectors on valley section of manifold for S/c, they are all dowel holes to line it up or bolt holes for attaching the S/c to manifold.
help guys...
can provide photos tomoro when light again

they are not direct injection. they are in the inlet port on the head. if you look at the pic i posted before. you will see where they go. to put the blower from an L67 on to an ecotec. you need to swap heads aswell.
