Bored out throttle body:
About the biggest you can go before degradation of sidewall integrity is 65mm. I may be wrong but I don’t think any companies do this. You have to remove your throttle body and take it to a machine shop. Make sure you take it to a reputable place and make sure they cut the butterfly plate at the proper angle. Some people have had idle problems (including myself) after installing one. In most cases after driving around for awhile the idle will settle down to normal
Aftermarket ignition:
MSD:

Jacobs:

I don’t have much experience with the Jacobs but I hear that it is possible to install. I have installed the MSD and am very happy with the results. To install the MSD you will need some basic electronics knowledge and a modified distributor cap. If you have a 93-94 you can get a special adapter from MSD for free and not have to cut any wires. Otherwise you need to modify the disty here is the write up

An aftermarket ignition will allow you to run a larger gap in your plug, give a multiple spark discharge for a complete burn, and should improve gas mileage, throttle response, and power.
Intake manifold:
There are many options here. You can search around for a used KL-ZE manifold, have yours port matched, or find a Eunos manifold., All of which will open the ports up a bit and allow for more air. There are some problems though. The Eunos manifold has clearance problems and the ZE manifold requires a bit of fabrication and creativity to get installed keeping emissions in tact. For the ZE manifold the throttle cable will need relocated and some of the vacume lines will need to be tee’d. Also if you have the stock ECU your VRIS points are not going to be correct. You will need to somehow change your points either by a VRIS controller or by re-programming your ECU.
http://corksport.com sells the ZE manifold for an ungodly price. Your best bet is to watch the forum for someone who is selling one.
Adjustable Fuel Pressure Regulator:
Cosmo: usually on E-bay
Aeromotive:

I use the Mallory and am very happy with it. It now has 1, -8an or 1/2" input and 3, 3/8" additional ports. In addition it does have a 1/8" npt port as well. The bypass or outlet is also -8 an or 1/2". You will need to get the appropriate steel braided hoses as well as fittings to install this. You will also need to get Mike Baxtors FPR adapter from
http://mbxmotorsports.com You can remove your stock fpr, plug in the adapter, and run the lines to your AFPR. All the fittings and lines can be purchased from
http://sumitracing.com The draw back is it doesn’t hold fuel pressure so it may take a bit longer to start the car in the morning. This can be resolved by giving the car a quick crank let it sit for about 2 seconds then turn it on. The adjustable Fuel pressure regulator allows you to adjust your fuel pressure to give the perfect about of fuel for your mods. A dyno with an Air Fuel bung is required to tune this properly.
Fuel pump:
Walbro in tank:

Highly recommended! Especially if you have your stock pump your old one may be getting tired. In my opinion the walbro is the best. A 190 lph will be perfect for a stock replacement and even a shot of nitrous. However the 255 high flow is not that much more expensive. You might as well get the big boy to plan for the future. A fuel pump is required if you plan on running lots of boost or nitrous.
Still more......
