Hi Josh.
I'm in the process of getting an EK9 that's coming with a B20 fitted. It will have a B20B3 block and Integra (ITR) head, looking around 200 bhp. There will be more powerful cars out there but it's the torque you're getting from the conversion that's important.
There will be die hards that say this doesn't matter but it does. I'm not slagging off the VTEC engine here as the B series is a wonderful engine, it really is. I currently drive a CRX VTEC 1.6 which has the B16A1 engine, it's done a few miles, coming up to 196k and is nearly 21 years old but it still goes fantastically well but I do miss the extra power I'm not going to lie.
Mine should be running 150 bhp but because it's old it's probably a lot less than that now. I had a blast against an EK9 a few years back on the dual carriageway towards Chester and the EK was a lot quicker than mine, you could see the difference in the 30 odd brake between the two engines.
Imagine having that sort of power but without having to ring the neck out of it and with more torque you'd breeze past cars effortlessly. Don't get me wrong I love hammering the CRX, it makes a wonderful noise but with a B20 you don't have to do that everywhere you go but the good thing is, if tuned properly it is still capable of being nailed, it's just a bit quicker and nicer to drive. Many people say the B20 is as quick in 4th/5th as a VT is in 3rd.
A lot of CRX lads on CRX UK believe that most performance Honda's should have come with the B20 as standard, it's that good a conversion. There will be people who disagree who enjoy revving their cars who prefer the B18 or still the B16 I don't disagree with them it's each to their own but think of the low down power and the ability to still rev high and that's what you will be getting from a B20.
BTW it's a myth that the B20 can't handle the power and blows up. Make sure you take it to somewhere reliable. Daz at DNR/Endless Horizon is very good, probably the best around when it comes to the B20 - I'm getting mine off Daz it's one of his own cars and he has a great reputation with this build. There's a guy called Romain who tunes or used to tune Honda's who is supposed to be very good but I'm not sure if he's still about, seem to be a lot of companies in Ireland who do the conversion so may be worth looking there too.
HTH buddy!
