    I have recently bought a prelude s and the motor in it is the b20a6
    I can't find any specs on it or anything
    Is this a jdm motor??
    is it the same as the b20a5?
    Does anyone know the horse power it pushes out???

    you sure its a b20a6? do you live in america? the b20a6 is from a 1988-1991 prelude s off of the new zealend and australian domestic market, its rated at 140@6000 rpm thats 5 more hp then the b20a5

    nevermind, it is a 5 not a 6
    so it's a b20a5 in my 90 prelude s
    Is that the si motor though, or is that the stock s motor???

    yea thats the si motor, someone probably swapped it before you, you could probably tell if you carfax the vin number or something but that costs money so idk what to tell you except congrats on having an si!

    ehhh...wrong. all US 90-91 prelude s came with B20A5, Si came with B21A1. all US 88-89 s's came with B20A3, Si came with B20A5.

    re-read my post. I know you have a '90-'91 right? B21A1. think about this and my earlier post. in canada the B21A1 came in the SR. but since you said 4WS Si i will assume that it's a US model, correct? and no the B20A5 came in the S model for '90-91. end of discussion...

    you are a liar! JDM B20A for the 3rd gen lude doesn't have 160hp! I wish cause i have the B20A. it's rated at 140hp. so what you're telling me is that you have a 3rd gen jdm accord B20A which makes 160hp in your lude. liar, liar, liar!!! it is not ideal to use that motor cause unlike the lude's B20A it is completely different. the ludes motor leans towards the firewall because of the low hoodline. the cord's is the opposite. it leans towards the radiator. so if you do infact have the cord's B20A then congrats on finding the hardest to find B20A. but has it blown up yet. cause it should have due to the fact it has to lean towards the firewall in your car. or did you cut a big ass hole in your hood to fit it? liar!!!
