I need some help if anyone knows these casting numbers.

After dealing with a few TPI systems now, and having fourlower intakes in my room... I've forgot which years are which.

I went ahead and got two casting numbers.

I believe the one off an '85 is : 10066016 I assume it would be the same for 86?

I also have one that says 10066013 I'm unsure of what this one is off of.

I have another 85 downstairs that I'm about 99% sure is a 85, but I haven't managed to get the casting numbers yet. I also have another one, but I haven't got to it yet.

If anyone knows the casting numbers of any of the years please let me know.

The runners I can tell the different between, the injectors I've learned, the TB, IAC Housing, and Plenum all have date stamps. The lower intake is the only one that is confusing me.

 

anyone? anyone who has a spare TPI intake laying around and knows what year it is, could you please tell me the markings on it.

 

easy way to tell is if all the bolt holes are the same angle. If the two center bolt holes on each side is more vertical than the other two sets then it is an 87-92 intake. If all the bolt holes are the same all the way areound the intake then it is an 85-86 intake.

 

Alright, I'll look at them and try to tell. The only probably is what if I only had one intake and was trying to tell which year?

But I'll use that method for now, if anyone has any casting numbers, please post them.

Thanks.

Big thanks for that link, exactly what I was looking for.

Can't thank you enough.

 

Hey if anyone else is looking for this info, the above link no longer works. This one should provide what you are looking for:

TPI is listed as PFI(port fuel injection) on the spec page

 

Nice one; put that in my bookmarks
