Ok im trying to figure out a few things. Im planning on running low boost (like 6 psi) for a while until i get the money to do some serious upgrades to run anywhere from 16 psi to 22psi in an older 88 honda accord with the cast iron a20a3 engine. Its a 2 liter but im unsure about using a big turbo like a t3/t4 or a t4 because the engine redlines at 6300rpm and is limited to less than 6800 rpm so id need to to spool and make alot of boost quickly, this aint no b16 that revs to 8100, so what kind of turbo should i go with? If i run high boost like that can i get away with the honda computer if i fool a few sensors and run huge injectors and big fuel pump or will i have to go stand alone? basically i wanna make the car run in the 13s or 12s

 

First question,

How much money do you want to spend?

because you probably could make a larger T3 from a Ford work on your car, or a DSM 14b may also possibly work. They are pretty cheap and can be found at local wrecking yards.

The t3/t4 57trim with a small A/R will work also, You shouldnt have to much lag, )depending on exhaust size, and manifold design.) it will cost about 500 bucks, but you will have a brand new turbo.

Im thinkin id just get the t3/4 just for the peace of mind. Im just not sure about fuel management yet... Any ideas? Also can i run 18-20 psi (if i change my pistons)?

 

50 trim T3/TO4E, 63 turbine... the best turbo ever made.

 

well i saw an older A20 accord with a 120 direct shot hit 13.9's and it was an automatic. The guy said the motor handles it well.
