dude, the b20a5 has a 1.48 r/s ratio.. and no, that motor has 155 to the fly, hed be lucky to see 220 to the wheels without blowing it up .

ok...im here to school you ----------ers because ive done this exact setup before.. ..and more than once.

First off...the b20a5 is 135hp with 111ft lbs of torque to the flywheel putting a meesly 100hp to the wheels...i put 10psi on mine and it pulled nicely, very nice in fact but you have to figure your car weighs around 2650 to 2700 lbs. your going to blow up the motor also...it always happens...first turbo motor always blows up with these things.... your best bet with 8 to 10psi is go safc hack and 450cc injectors with a walbro 255lph pump. you will go lean with the stock pump...dont go with a big *** turbo...just go straight t3 turbo like off a saab. 14b will do suffciently but in my oppinion it spools up a lil too quick and doesnt have the pull a t3 would provide you on the highway. no one makes manifolds for these cars unless you get one custom made from a local fabrication shop....manifolds from other b series will not bolt up...your best bet...get rid of the car...buy something that can rev higher without blowing rod bearings past 7k rpms....but since its what you got...build it. with 10psi...the only cars you will be able to beat are mustangs...firebirds...trans ams and various other pieces of ***** out on the road...and only if your a good driver...i should know...i did it myself. Words from the wise...have a spare block laying around cause your gonna blow ---- up the first time, mostly because of improper tuning. oh lord i dont feel like typing everything you have to do so im out.

p.s. the 2 main reasons why i got rid of my prelude....the weight of the car and the motor in it.
