Might be wrong forum but its a pretty general question.

About how many streetable NA ponies is a B18 good for?

 

USDM: 170
JDM: 180

 

I mean completly modified w/o N2O or FI.

 

Define "streetable" and give a rough estimate of budget.

 

but you just said n/a in ur first post

 

NA = no FI or N20 :slap:



And just for the record, measuring something like this is so completely broad, there are almost an infinite number of variables that its so hard to put a specific number on it.

 

But to do just that, 240-250 whp is about where you'll top out with anything resembling streetable. However as Dom Toretto would say, that's "not a bad way to spend ten grand."

 

yeah, cold air intake with your t-66 turbo is a good idea


:chuckles:

 

my bad i overlooked the ''w/o'' in his 2nd post

 

It's got a NOS fogger system, cool air intake, AIC controller, direct-port nitrous injection, T4 turbo, and a standalone fuel management system.

So yeah only the fogger/direct-port and AIC/standalone are redundant.

But to put 240 whp to the ground with a B18C you will need some kind of free-flow intake, bigger throttle, new manifold, ported head, really spiffy cams, 12:1 cr, bottom end that'll rev to 9000, resleeved and bored out to 85 mm, spiffy header with a 2.5" or maybe even 2.75" collector and piping of a similar diameter back to a straight-through muffler. Plus I would say 370 cc/min injectors, an upgraded fuel pump and an electronic means of tuning everything (V-AFC, Hondata, AEM EMS, etc) and adjustable cam gears. With all that crap dialed in you could probably hit 240 to the wheel.
