Has anyone thought of dropping a b16b motor into the Fit?
It seems much easier than dealing with the weight problems of the k20 and the b16b type r motor revs to 9k and they're about 3-4000 used.

if somebody can chime in....how feasible do you think this process would be? I mean this could be an alternative to the KWSC if it doesn't cost more than 6000 like the k swap.


just putting some thoughts out there

Thanks

I know it's been done before, but I honestly have no clue if it was posted here or elsewhere. I think it was a Japanese Fit it was done to.

 

it would cost almost as much as a Kswap cause of all the custom fabbing that would be needed. Mounts, axles, harness etc.

 

ugh my hopes have been lost

 

PLUS B series weigh just a hair more than K series

 

which one?

b16 or b18?

i'm pretty sure a 1.6L motor should weigh less than a k20

 

well i know for a fact that B18C weighs a couple of pounds more than a K20a.
but if the b16 does weigh less it's only 20-40 lbs

 

20-40lbs may not sound like a lot, but it's 20-40lbs that's not over the front axle.

That said, it's far cheaper and much less of a hassle to build and boost the L15.

 

Any one ever take the time to sit back, and look at both engine bays.. hmm


after u yahoo/google a view image ..

you will then notice the engines sit verry different..
look at where the the intake manifold on a b16 in a car.. then look where current intake manifold sit..


imo work your stock engine to the power of a b16.. plus that engines old already .. if ur gona spend that kind of money making those kinds of mods.. go for a more powerfull newer engine like a k serious

 

Been done to death added R swap also

There's MORE just scroll through JDM tuning,engine mods and swaps forum and take your pick.

 

bseries are so weak when compared to kseries. The money you'd spend would end up being just as much because of the custom fabbing. I've seen it done, but all motor bseries worked < kseries w/ a tune and cams. In the end a kseries is still going to be your cheapest bet.

Typical power I see out of b/k series when we tune.

B20v(gsr head IM/H/E/CAI/Hondata s300 other misc. mods)- 170 ish whp/ 140ish tq

K20a2(RBC Intake Mani/SRI/DTR 4-1/ open header/ Kpro) - 214 whp/167 tq

In order for a bseries to even get close to these numbers it is going to have to be 84mm-85mm bore, C.R. of 12.5 and ^, equal length header, bigger IM, cams( like skunk p2's), equal length manifold, etc etc. You could see 240whp+, but it will never make the tq a kseries makes.

Don't get me wrong, I love bseries, but kseries just makes more power, and alot easier. You may see cheaper costs up front, but in the end, you will end up paying the same honestly. For imo, a less reliable motor with less power.

Btw b16b's are a joke for the price. If I were to do a bseries build I'd pick up a b20b for around 400-600 dollars, and get me a gsr head. Anyway let me stop now before I go on forever. In all seriousness though, if you have any questions about b/k series, feel free to pm me. I study alot on this sort of stuff and help build/tune them on the regular =)

 

why would you pay just as much for an old, gutless engine?

 

i was thinking the type r motors
i thought it would've been a cheaper/easier/lighter swap than k20 and still with decent hp..


not worth it i guess

Honestly, I like the look of a boosted bseries in a fit. It looks kinda cool. I would just go with the T1R kit. It's going to make more power than the kwsc and I believe is the same price.

People that are worried about boosted motors reliability read too many ignorant posters on the web. A boosted car is going to be pretty damn reliable if it's tuned right and well taken care of. You can't get pissed off cuz your damn car blew up because it was tuned for 6 or 7 psi and you decided to turn it up to 12 psi or whatever and blew it up. As long as you have the right a/f's, and not TOO much boost, the L15 will be fine, especially with the size turbo that comes with the kit. My props to T1R and KW for both of their kits. I was impressed with the power they both made.

 

x2
definitely sheds some new light on the potential on Honda's virgin 1.5L L15 motor

 

Seriously, if the head had more potential, I could see some power to be made. 200whp is gonna be about where its at with these motors though. The ports are just so damn small. 200whp is still going to be pretty quick in such a light car. I'm sure it's alot of fun on the track =)

 

as far as moding the lito L15..

not saying there is never big potential for a 1.5 BUT..

IMO most of the power is gained through the head.. and the L15 has shitty flow

 

IMO most cost effective swap is a K24 from an accord or CRV and a 5 speed RSX tranny. $1800 for motor and tranny. 160hp/160tq. Plenty quick and given the lightness of the fit and the gearing in the spd rsx tranny it'll be higely driveable with relatively short gears and a broad torque curve. Also there was a build up of a K24 (non TSX) that made some crazy numbers.

 

H series!! lol, just kidding.

 

Is there a chart that shows the weight of all the honda motors? Just to get an idea for comparison. ??
