Didn't they ditch the 9th injector (cold start) in '89? If so, which version do you need, with or without the provision?

I'm going off memory here but you should be able to use an early cold-start intake and just not hook the injector up.
What you want to watch out for is the later ('90-'92 IIRC) intakes with the extra runner. You can ask John and James about that one!  |

| Quote: | TPI Upper intake, lower intake, runners:
1985-1988 had provisions for a cold start valve. If you are going to use these, you will either need to use a chip for '86-'88 systems, or use a newer ECM/chip combo, and block off cold start system. A fuel rail cap and CS valve plug is available to do so.
1989 was delete of the cold start valve, so the upper intake (plenum), runners, and lower intake do not have provisions for the valve.
1990-1992 was also delete the CS valve, but also had provisions on the Plenum for a MAP sensor bracket above the vacuum nipples on the rear of the Plenum, since '90-'92 was speed density controlled. If you want to use a TPI off of a Corvette, be carefull, the lower intake was made to bolt up to cylinder heads that do not have EGR passages, so you won't be able to use a Corvette intake, unless you want to delete the EGR.
Starting in 1987, the angle of the four center bolts of the intake changed, so if you wan't to use a pre-87 intake on an '87 or later engine (or vice versa) you will have to modify the four center holes to make it bolt up properly. |
Also you could buy one of these if you can only find a pre-'89 intake:
