TPI runners

[keith2717]

Can you put 88-earlier runners on an 89 and if so what is the difference
the cold start. If you put the 88 earlier runners on what would happen.

you just have to plug the cold start injector hole to put them on the later cars as far as i know.

Here's what the one from Street and Performance looks like. Their website is www.hotrodlane.cc but it appears to be down for maintenance. The S&P parts are very nice, I just installed the 9th injector plug, fuel-rail plug, and EGR blockoff on my TPI motor over the summer.

Thanks, Bro. So thats all I need to do is block that off and im in buisness?

Yep, since you have an '89 you can use those by plugging the hole. Go for it!

Well, the blockoff plate is a really nice piece, and fit perfectly. Pros? A couple less vacuum lines under the hood, and no more EGR solenoid to look at. Cons? None, at least for my car. I got rid of the EGR since I have a ZZ4 cam and it has enough overlap to "self-EGR". In fact, GM got the ZZ4 crate motor smog-certified in Cali without the EGR valve so I know it should be fine, should I ever need to pass emissions again (thank you Collector Registration!). I just had to program out the EGR in my chip; if you remove the EGR and don't do anything in the program, I think it'll ping at light cruise where the EGR normally comes into play.
