well i hope its stick, if not ur first mod should be a 5spd tranny. Thats my opinion

if your boosting theres no use in getting headers you need an turbo exhaust manifold. For the exhaust the great thing about turbos is when it comes to exhaust bigger is better. Go to a muffler shop and get some big piping custom made for your car, it will be a lot cheaper. As far as turbos go im not sure about your accord but the best way to figure that out is to do research. Some people can give you their opinions but the best way to get the most bang for the buck is to do research.

Wouldn't realy matter because I'm not goin to drag it. Also, the engine won't allow the RPM's to go higher than 6000. Its better that its auto because when you slam on the gas it drops to the lowest gear it can run at. Its just a hobby/project car. just needs so more power&torque.

correct me if im wrong but you dont want to go too big on the exhaust, there is such a thing as too big. IF you get too much back pressure cause your exhaust is too big doesnt that mess up your tubo?? Depending on your turbo set up you should get 2 1/2 to 3 inch pipping.

I might be wrong im not a turbo junkee but i think that with a turbo since it is the exhaust gasses in the manifold that spool the turbo then everything behind that does nothing but choke up the exhaust flow. But dont take what i said for gold ive only installed a couple turbo kits, ive never gone too in depth with them.

To some degree, too large of an exhaust is bad. It's very common for boosted cars to lose low-end power from a huge diameter exhaust. Personally, I wouldn't go larger than a 2.5" exhaust unless I was making over 500whp.

On n/a Hondas anything over 2.5" is not going to create enough backpressure and actually lose power, so bigger is not better. However, on turbo cars the backpressure is not needed to create velocity, so bigger is better 3" is a good diameter for turbo Hondas. Thermal makes turbo 3" exhaust systems for Hondas.

This is true, but like I said earlier it depends on how much power you're already making. If you're running 10psi on a T3 and already have 2.5" piping and upgrade to 3", more than likely you'll lose low-end power with a high-flow exhaust system. I do believe Thermal uses a muffler in their system just like all the others - don't tell me that the muffler doesn't cause back-pressure.

i'd go with a turbo kit in your case because it doesn't look like u really want to get involved in a whole lot of power and it'd be a waste to turbo an automatic because torque converters and automatic trannies in general can't handle a lot of power or manage it well. also if your turboing a car, the ecu will have to be upgraded to allow a higher fuel/air ratio so you don't detonate the crap out of your engine + the ecu will eliminate or raise your rev limiter. I say either swap to a manual or get rid of the turbo idea.
