Mass Air, TB, EGR Spacer??

[GearHd6]

I've got the car listed in my "sig" and was wondering what combo of Mass Air meter, throttle body and EGR spacer should be. Its got the stock 19lb injectors too. Engine has stock internals and the bolt on's listed in the "sig". Or should I just keep the stock stuff? Thanks!

You won't pick up much by going larger now, wait till you want to upgrade the heads and intake.

Then go larger inj 24#-30#, 70mm TB and a 80mm Pro-M MAF

The stock parts are as follows:

MAF - 55mm / 19lb calibration
TB - 58mm on 1987-1988 / 60mm on 1989-1993
EGR - matches the TB

One of the easiest upgrades is to replace the restrictive MAF with a 70mm or larger unit. This change corrects a bottle neck in the upper RPM range of the motor. The swap usually takes 10 minutes or less (assuming you get one calibrated for 19lb injectors)

Popular Brands are:
Professional Mass Air (formally Pro-M)
C&L (very common)

The 19lb injectors are good up to 300HP or so.

If you stay N/A you will be fine with a 65mm TB / EGR.

There are a lot of good brands for TB/EGR's.

accufab for TB, and pro-m or C&L for mass air.
