Hi, I was just wondering how much WHP you can get out of a N/A 20B with extended ports and polished housings ???

 

I'd say 400 should be attainable with a good port.. I'd use the FC N/A high compression rotors in it as well and 13B housings...

RE Amemia got around 550 hp out of their pink and blue car... but it has some serious throttle body and runner work done to it.

 

has a peripheral port too

I would guess a little over 300hp. Hopefully you could get about 300rwhp
This would be without a bridgeport or peripheral port. And streetable, and only guessing :-\
Not many people with streetable N/A 20bs so not much to go from

 

Well all kinds of porting is streetable in New Zealand.
There is a company here that specialises in 20B rotors....when I have the time Ill check out how much a brand new one is...I am happy with around 380RWHP N/A if they can get that....it would make a nice reliabel street car dont you think.....no turbo problems and stuff...just a nice sounding 20B N/A. Well thanks for the help guys. Post some more info if you can.

Cheers

Hey, since I've gat a New Zealand guy here... you know of anyone who need some Cosmo parts as I have a whole car that I'm only using the engine out of... I have a full T45S turbo kit with manifold and front pipe and wastgate and ofcourse the turbo..

 

i'll take one please

 

Nope sorry mate!!!....dont know anyone.

 

ROB GOLDEN SAYS A WILD ONE COULD GET 425 ISH BUT REALISTICALLY A STREET DRIVEN 20B NA WOULD BE AROUND 300-325HP.
DEF USE HIGH COMPRESSION ROTORS THO.
OR DON'T IF YOU WANNA GO CHEAP.

 

if you're up for a nice lumpy idle and shitloads of topend you can always bridgeport it and still have it be streetable, well some people don't consider bridgeports streetable, but there are some people who drive them daily. Would be loud as bajesus though.
I think a peripheral port is just not really streetable, idle at 2k, no power till what....6k or so?

I think you should just go with a huge streetport and aim for 300rwhp or so.
OOOOOOOOOOR how about a 4 rotor 12a? Not too much bigger, and the parts are cheap, custom eshaft, and figuring out how in the hell to mount it. hmmmmmmmm, oh well, just an idea lol

 

Scoot is supposed to have their 24A up and running at the moment. It should be appearing in some of the Magazines shortly.. That should be one pissed off engine..

 

mabey I'm wrong but wasn't jesus paldila (sp?) pushing more than 500 hp with his all motor 20b? His quarter mile time record is 10.2 seconds.
