Next week I am going to be spending some money on the 1990 auto sc. I am thinking about upgrading to a late model sc'er/plentum and fmic 2.75 piping(cxracing)...I have 3 kids and another on the way so I have to budget to do upgrades to the car. The exhaust is getting the resonator removed and replacing stock mufflers with 2 flowmasters next week also.....thought on this poor mans performance upgrades?

Should wake it up a bit. Could probably throw a 5% or 10% pulley on there too cause the larger IC will help with keeping it cool. See if they can make you some exhaust down tubes while its at the muffler shop.

That'll work good. You don't need the MP plenum until you have heads/cam and a much upgraded fuel system.

fyi...the 3" cx racing kit is measured as 3" od. The inside actually measures closer to 2 3/4" to 2 7/8". If the 2.5" is the same you are looking at 2.25" inside diameter.
