Hi all you third gens enthusiasts just looking on some suggestions on where should I start modding my 87 IROC. I have the L98 TPI of course one friend said to go for runners first. I figured since i signed up I might as well as you guys first before I start on the runners thanx in advance.

 

easier air in, easier exhaust out

gut the air boxs, port the upper plenum, install some headers, and a decent catback.

that should get you started.

after that it all depends on how much power you want.

but i agree with the tune up...plugs, wires, dist. and full fluid flush

 

Ok so I'm making a list here on what to do first so the tune up is a definate. So I will need to buy the following parts, spark plugs, plug wires, all fluids for a flush hmmmm what else should i need to get for the tune up I usually like to buy the stuff first before I take her to the mechanic.

 

It all depends on how much you have to spend and how fast you want to go.

 

As someone already said Get air in that way the car can breath better but at the same time you have to have an escape for that air. Headers & exhaust.

 

The biggest problem in the TPI system is the intakes. Change the intakes totally to say HSR or SR then go with the headers and EPROM and see how much more you want to spend.

 

You might want to get a distributor cap and rotor,don't just get the cheapo generic one either make sure you get a copper core type you will probably have to go to NAPA or somewhere that sells better quaility parts for them. Can't see spending good money on fancy wires then putting a cheap aluminum core cap in the middle.

 

Was checking out SLP and decided imma go with this exauhst.

I would look in to getting a set of Taylor wires from Summit.

 

yeah Taylor wires, no clue what size with 3rd gens use, but I put 8mm spiro pro taylor wires in the Z.

 

I have a set of 8mm Spiros in mine & mines a 87 Same set my husband has in his 95 camaro & his 90 vette

 

Accel 300+ wires and that exhaust should be good
