I have some questions for you guys about 90 preludes I have a si with a 2.05 thats blown so i need a new engine for it.first will a b20a5 hook directly to my wiring harness and work with my ecu or will i need to change it if i decide to change engines.What is the curb wieght for one of these cars.Compared to other 4cyl stock engines from this time how does it compare in speed and accelaration.I will be racing this car next year on a half mile oval and would like some input from some people who know these cars.

 

B20a5 is a drop in if you re-use your existing manifolds. Weight is 2700 lbs. Were fast for their times. Try preludepower.com for more info, tons of 3rd gen members
