Do '94-'96 lower intake runners bolt up to '90-'93 heads?

[3rd Q]

I've got my "94+ fuel rails and injectors waiting to be installed on my '90. Anyone know if the lower runners can be switched? It will make the install a little easier if they do.

Thanks,Paul

I have no way of knowing, but im pretty sure the plenums are identical, which seems to me that they may work.....

Wes,I thought I remembered a post where someone said they would not match up correctly, but can't find it with a search. Maybe someone will chime in.

Me, Squee, and Q45Denver are all ready to do this and I think each is hoping the other guy is the guinea pig to go first.

I think I have another injector acting up- may need to replace my 12th injector in this car in the past 2 1/2 years ! May just switch the '94 rail in while I'm in there.

I don't think they'll fit because the intake design is different. If the weather holds up I'll check this weekend. I think all I'll need to do is bore out the center of the spacers/insulators to accept the smaller diameter ones from the 1994. My garage door just came off its tracks so I need to deal with that as well. Main concern was that the tip of the 1990 injectors extends about 3/8 of an inch further in to the intake port but probably not significant. Might actually help to lessen the heak soak problem the 1990 one experience.

It was my understanding that everything fit except the gaskets/isolators and the harness connector.

Paul's right about the guinea pig effect...

I'm doing body work right now, then rack boots and the still notchy steering.... then more chain guides.

Coming soon... pics of Q45 rot.
