B20 Engine???


Well, every fully built B20 motor I've ever seen running has blown up... so most of them are not reliable :nerv:

Thats would be one with loads of aftermarket parts? I.e cams, biggers pistons etc?

I think a standard b20 with a b16 head would be fine if not reved over 7500 rpm?

Yeah, the motors had aftermarket camshafts and bigger pistons, but hmmm.. If I install a b20 engine I want to be able to make power all the way up to 8200 RPM at least!

I have friends who run a stock B20 on their civics for track use only, no vtec, and they still blow up motors..

Well then you would have to sleeve the block etc.
The stock b20 block should not really be reved about 7500rpm. And they are probably reving them more than that no?

sounds like they weren't built properly to begin with.

There's no way you can expect a motor that was originally designed to be used in a station wagon (Orthia), light SUV/van (CR-V/stream) to act like its performance vtec brethren without first considering all the weak points (many).

Just the bottom end itself is lacking the block girdle, the under piston oil jets (essential if maintaining cast pistons) stronger rod bolts/rods, oil pump. Then there's the issue of the thin cylinder walls.

If you want a B20 to last - then spend without compromise and start with a "junk" B18A/B block and have it resleeved to begin with .... and then? Keep adding parts as the science of reliable B20 motors is just a matter of money.
 
I reckon i'm going to go ahead with this B20 into my EK9, but still have some doubts because of some of the comments of them blowing up and not bein reliable? Ive been in contact with a company about a b20 and they offered me this build, i myself feel very happy with it and more than likely going to go ahead with it but would like some opinions of other people before i do.


-B20B block supplied, stripped cleaned and inspected, any problems dealt with before fitting
-Golden eagle B20 conversion kit
-ARP rod bolts
-Your B16B head stripped and rebuild (new stem seals, valves reground)
-If your B16B crank girdle is in good nick I could swap this over to the B20 too, not essential but a nice little extra if its not damaged
-OBD1-OBD2b adapter harness
-OBD1 ECU, socketed running crome
-Dyno tuning session and printout
-Complete engine service including all fluids, filters etc
 
Its performancetek in Glasgow, the guy has prob done every engine swap possible. Price seems fair to me, roundabout the £2000 depending on a few things. I ain't got back to him yet as i'm still in two minds.
 
Well its sounds good, is he goin to guarantee it? What was the B18C-R swap goin to cost you in comparison?

not essential on a daily driver perhaps... but very essential if you plan to visit a road course and do some lapping.
 
Nice write up homie....u jus educated a brother in trinidad on how to do this B20 Build...down here we call it a frankenstine bcuz it creates a monster
lol
