Hey,

I need to do a tune up on the GTA i just bought.
Please let me know if these parts and numbers sound right.
1989 GTA 5.7L stock (for now)

delco plugs R45TS
MSD cap 8433
MSD Rotor 8410
MSD Coil 8225
MSD wires 31229


Please let me know if these numbers are correct. I did alot of searching and this is what i came up with, but i want to make sure because i saw some other options.

oh, last thing.
Are these the only longtubes that will not have problems with clearance? Will the wires and plugs work ok with this setup below also?

You can't use long tubes on any smog motor in California. The set you linked to have no provision for a.i.r. tubes. Long tube also will not work with a cat in a Third Gen, there just isn't enough room under the body. You must have a "Y" pipe connecting the left side to the right side going to the cat (cats in the case of a dual cat car) under the front passenger floor. Even if you installed the a.i.r. tubes on the long tube headers, I don't think you would have room to get a "Y" pipe to cross over to the cats without having the pipe running under the tranny. You will also have ground clearance issues with both the long tube collectors and any crossover pipe you can fabricate.

The good news is that Don's headers will work, and pass smog. There are a bunch of cars in this club running Don's headers and making 350+ hp at the rear wheels on smog legal motors.

 

Russ,
thanks for the response but i know all that all ready.

I dont want to buy shorties if these long tubes and ORY-pipe cost the same as Don's headers and new cats. Not sure how much Dons cost but everything else i was looking at (shorties + cats) was about the same price as long tubes and ORY.

I dont mind using long tubes but i just dont want any problems with clearance. If these long tubes will clear fine, id like to use them but i dont want to have to bang on anything to make them fit other wise i will just go with shorties.

Id like to know if those long tubes will clear without issues.

Does Don have a website?

Are those the right part #'s to buy for plugs etc....


thanks

 

No web site, but here's my setup:

 

sent PM

 

how do you get ahold of don ?

 

He's first one listed in So Cal Third Gen Friendly Company's at top of Forum.

Looking at the installed photos on Hawk's Website, it looks like you might lose a little ground clearance with their long tube set-up.

 

Don is very busy right now, busting his butt to get as many customer's cars ready as possible for the LA Invasion over Memorial Day. Forgive him if he doesnt get back to you right away.

 

my big question right now is if those parts above are the right ones to buy for my application.
I did some more searching and came up with these.
Does anybody know which ones to buy

MSD plugs 31229
msd cap 8426
msd rotor 8427
hei bushing 8412

thanks

5.7L 1989 GTA

 

i ended up buying these, hopefully they are right.
Now i just need don to call me back and also figure out what cats to go with his headers and an o2 sensor.
To bad it wont be ready for the cruise

 

Magnaflow cats and a genuine AC Delco O2 sensor. Dont get a Bosch.

I dont have a clue on part numbers as I just walk into the auto parts store and tell the flunky behind the counter what I want. I have about 4 different cars worth of parts on my car so I cant keep track of all the part numbers.
