i have a 1990 accord with an f22a1 motor that i want to turbo charge but i dont know where to start can some one help me i would really appreciate it cause i want to do it myself but like i said im a beginner

my car is a 5 speed

you asked a similar question with reguards to a super charger, the answers are the same, your not looking at anything else, you also dont specify if its auto or manual (i work for honda and ive never seen a manual accord in that style) No honda automatic transmission can handle that kind of increase, especially without alot of custom work, ive only seen one, and i repeat, one, 5 speed accord v6 and thats cuz the kid did custom work, those are luxury not race cars, your motor may be able to handle it, but your tranny wont
but to flat out answer your question, turbos offer a gain anywhere from 50HP and up with proper tuning, fuel system, engine management

A good place to start in any car whether it is SOHC or DOHC is in weight reduction especially in a SOHC car. Other good ideas are with the AEM CAI. If your mechanical skill is at a more advanced level you can move on to timing pullys, ignition timing, header, upper intake manifiold, new plug wires, new plugs, internal engine components such as valves, valve springs, forged pistons, port and polish the head, Skunk 2 camshafts, and up to turbo or supercharger. I dont recommend a turbo for a daily driven car. The cost on a turbo upgrade is insane. It can run you upwards of $4000 even if you purchase everything off of Ebay. The turbo itself is only around $1000 but by the time you upgrade your ECU with a piggy back system new fuel pump, new fuel rail, new injectors, turbo timers, and put in a block guard along with all these other upgrades to get maximum performance you wont have very good gas mileage and it may not be reliable from day to day. You can take the cheap route and just drop in the turbo and start racing but I can assure you the motor itself will not hold up long. Honda blocks and ECU’s are not made for turbo. Without proper attention you will run extremely lean and burm a hole in a piston or overboost and blow a hole in your block. It has been said that the honda block can handle 7lbs. of constant boost well but we are all power freaks and we will keep adjusting the boost up until we are satisfied and without proper tuning and build up it wont last.
