Default Modding my 90 coupe

I am now stock. Could people list their first 5 mods, costs and gains I can expect? I am ready to compete with most anything on the road.

I don't really have a first 5 mods,I kinda did it with one shot. I would do TPIS headers, TpiS catback, open air lid with K&N, ADJ fuel pressure reg, and under drive crank pulley.
Headers-750
catback-600
air lid and filter-75
Fuel reg.-100
crank pulley with belt-100
With a solid launch very low 13's with a 6 speed car (possibly into the 12's....Vic89 for example)

I'll asume you mean engine/drive-train mods; mine are on my site.

I'm sending you mail with results of various engine mods.

All my mods are listed in the signature in the order they were installed.

I would do exhaust first, that is the biggest restriction.

All the other mods will give you small gains, but remember that 5 small mods will add up nicely.

All bolton L98's should run low 13's very easily.

My first five on my 90 coupe were:

1. K&N air filter w/ open cover ($100)
2. Accel distributor cap & coil ($70)
3. Taylor SpiroPro Wires ($60)
4. AC Delco Rapid Fire plugs ($30)
5. Flowmaster Force II cat-back system ($500)

The most significant improvement from all the above is that it sounds cooler...

Mark
