The OEM ignition can handle more than you think. People boost on OEM ignition. OBD1 is much easier to tune since emission laws are less strict...less sensors and crap.
What are you your future plans for the car? Swap? Boost? Nitrous? I was going to say a lightened flywheel and stage 1 clutch would be an awesome little upgrade. Or even like an Exedy OE clutch (grabs slightly harder than OEM). The engine revs faster with the lightened flywheel. You could always lower it and put on a rear sway bar. These cars are great because they're so light. Some nice 600-700 spring rates and a 19-22 rear sway bar will make it handle awesome. And don't forget some nice grippy tires.
If it's bogging, it could be a wide variety of issues. How many miles are on the car? When was the last time a tune-up was performed? You may need a tune-up. I run fuel injector cleaner every 3-5000 as well.
I say paint the lip and get an OEM Si grill and get that paint matched. I used to have a Type R style grill and an OEM Si grill looks so much better.
Well John lets see, swap-wise, Ill be swapping to a manual trans. Though I may also swap to a B16 as well. But for the now Im chuckin this automatic. This automatic is just crapping out on me as we speak. I already installed the clutch and brake pedals mostly because I had them and apparently they were in the way. So the best way i could think of to move them was to install them. Besides that that is supposed to be the hardest part from what I hear. Im not planning to boost or nitrous. Just make it a bit quicker then it already is. For the exhaust i have a DCsports header, high flow cat, and a greddy spectrul elite cat back system.
I am concidering the Tein lowering springs, I already have a 24mm rear sway bar from ASR as well as the rear brace. I Im also running front and rear strut bars from Skunk. I also would like to upgrade the front sway bar as well. It is a daily driver so i cant get too wild with mods. But I think the sedan could be a cool baby getter
As for tune up, Ive done air filter, plug wires and plugs. I havnt changed the fuel filter yet. But the thought has crossed my mind.
