How achievable is 400Whp and N/A

[RedSolAZ]

I would like to get into the 400Whp range. Can this be reasonably done and still be street legal? And be somewhat reliable. $$ not a big concern as this build is going to take a while.

Also.
When does Sleeving and block guard come into play?

[*inFamous*]

naturally aspirated, you'd have to have an insane budget not to mention it woud'nt resemble much of a honda motor once u were done with it (assuming your speaking of a honda)

[SOHCsoldier]

Wow are you serious? Not with a 4 cylinder honda motor bud

[*inFamous*]

step one

take a block of aluminum, make cylinders, total displacement 4 liters

step two

set it up for 15:1 comp ratio




good luck!

[soooofit]

Wow are you serious? Not with a 4 cylinder honda motor bud

are you serious??? j's racing has a k24 fit with 324whp all motor

[*inFamous*]

are you serious??? j's racing has a k24 fit with 324whp all motor

lotta money in that motor :)

were talking about the average pesron with out access to R n D machines :)

I know the 275whp mark on a K series is doable with reasonable amounts of money, but that 300+ border starts getting REALLY pricey

[azianretard]

All u need is a fast enough stock car, and work from there, say a 350Z

[SOHCsoldier]

are you serious??? j's racing has a k24 fit with 324whp all motor

324 is 400 these days? Are you serious

[soooofit]

close enough!? and 350z??????? why not an s2000? lighter an better

[Scottsdaleindahouse]

close enough!? and 350z??????? why not an s2000? lighter an better

Why is it better? Becuase a 350Z will outperform it in every single category?

[RedSolAZ]

WOW!!! Looks like i created quite the Stir with that question. I didn't think that it was possible.

How much Whp could I achieve. I say the $$ not a big deal but only because this build will not have a time limit on completing

I would be using a B series setup. Not sure yet on b16b or b18c but this will be going into a Del Sol.

[RedSolAZ]

How about with using F/I and good build to support or is this still just crazy?

[advert]

close enough!? and 350z??????? why not an s2000? lighter an better

close enough... soo far off its not even funny.

people like you make me laugh.

have you ever even built a motor in your life? let alone tuned one?

[advert]

How about with using F/I and good build to support or is this still just crazy?

400whp f/i is easy.

you can do that with a gsr, pistons and rods and a lot of boost.

[boostedrex]

boost and u can do it

[SOHCsoldier]

close enough!? and 350z??????? why not an s2000? lighter an better

Close enough? You must not understand how hard it is to make all motor power.

[*inFamous*]

not to mention the VQ35 motor is much different than the F series motor.

[RedSolAZ]

Should i start with a sleeved block or can a stock handle this safely?

Should I start this thread over in the F/I area???

[*inFamous*]

I'd do somemore research on what your goals are, your budget etc before posting again.

When you post a topic like this, you'll get about 100 different oppinions and experiences from 100 different ppl.

You need to build a motor for whats in YOUR budget and one that will achieve your goals. Sometimes your budget wont allow your goals, it all depends on how you put it together (and cheaping out should NEVER be an option)

[WhosUrBuddiee]

The VQ35 is a very nice motor with tons of potential. Dont think you can ever fit it into a del sol though

[allbossbra]

400 hp n/a honda block = not possible

[SOHCsoldier]

400 hp n/a honda block 4 cylinder = not possible

fixed

[K20 PWR]

you can always get like 280whp n/a and then spray. still not boosting it and still n/a IMO.

[Chinky]

here in tucson a kid ran a stock gsr and just tuned the shit out of it and mad something like 400 + whp. boosted of course

[Mr.Burner]

ya I think the most hp ever made on a b-series is like, what 298hp. spraying on it of course would do the trick, but even then your dealing with F/I again..........
All motor b-series is becoming, obsolete as for making power. Or having a shit load of money and dont care about longevity,

If your looking to build a all motor B...
1.get a dart "tall block" 14mm taller
2.punch it out to 85.mm
3.get a 92mm crank
4.buy a set of custom length Pauter titanium rods
5.Manley titanium valves, springs, retainers etc
6.have the head hogged out to the max, big cams
7.GOOD TUNING.

[tokyospeedpros]

LOL, no doubt a 3.5 liter V6 vs a 2.0 {or 2.2} inline 4. Quite the difference. Also hard to achieve 400whp in a vq35 most of them put out around 225 or so to the wheels from the factory, horrible power loss through the drive train. Anyway in a 4cylinder honda 400whp is NOT going to happen. All motor is fun though.

[mottrhed]

lol dream on. 400hp n/a honda, that is f1 territory. good luck. just put a turbo on it and be done. alot less money, alot more relyable, and probably alot easier to drive than a 400hp n/a b series(but noone will ever know)

still not boosting?!! its a form of FI for sure!

adding more 02 into the chamber last time i checked was f/i. your opinion sucks, its not a opinion at all. cause its a fact that spray is f/i.

That is a fact my good man, cylinder pressure=boost!!

[no2psi]

400 whp all motor K series is doable. Just do the math.
NHRA import all motor cars are trapping around 145mph! At NHRA weight you need right around 400whp. So yea its happening or real close to it. Street car no way!

[DJ NeX]

^^^^ That's coming from one of the more experienced NA engine builders on this site.

Realistically, if you hit 400 NA, your car would be in no way shape or form a streetable motor. You would have the most useless powerband ever.

[honduh_head]

IPS is close...they just made 379 whp with their new cams without redoing their header for the bigger cams...but thats on a 2.6 liter k series at 15 to 1 compression....(Norris Preyunto's car btw)

just boost it man...much easier and waaaaay cheaper

Do you think they post their current dyno's...IPS never actually comes out and says much, just lets people make assumptions. Im pretty sure the traps show 400whp :)

um Norris himself is the one who posted it on k20a.org....they keep those guys pretty up to date with everything cuz they are one of the main vendors on there and their clients are pretty demanding on the products that IPS makes

So your telling me that if you had one of the top pro stock imports in the county you would
post your current dyno charts? Sure!

[Nott_Sure]

GM 572 crate motor :thumbup:

why not? ips is the one breaking all the records...what do they have to hide? it would be like a bench mark for people to shoot for...you dont see whats her face that just ran sevens hiding that she has a 1200 hp b series

[honduh_head]

GM 572 crate motor :thumbup:

that would make a lot more than 400 hp na....the regular ls2's do that with a cam and headers

well nos is another type of fuel. it is not making boost, making pressure and forcing more air to the chambers like turbo or supercharger. nos adds more fuel. i see it different as you thats all.

if you go as far as adding more o2 into the chamber would an intake, bigger TB etc not be f/i??? they are like you say adding more o2 into the chamber?? :p

I'm sorry, but when I read that I spit my water all over my monitor.

nitrous OXIDE is not fuel. It adds....you guess it! OXYGEN! What do we know about air? IT HAS OXYGEN! and OXYGEN is flammable! w00t!

If nitrous oxide was simply another form of fuel, then why don't we run cars by filling up the gas tanks with nitrous? Oh WAIT! that's because nitrous isn't FUEL! you can't put nitrous through a fuel injector and negate using petrol. Therefore Nitrous oxide ADDS "air" to the cylinders by forcing in more oxygen. Sounds like a form of Forced Induction to me...

but hey, what do I know I'm just a lackey. (as someone one put it)

[GNU]

yeah nitrous is very understood, very basic principle nitrous at the high pressures is a gas, at around 570 degrees it breaks down and releases extra oxygen, and when the extra oxygen is supplemented with the right ratio of fuel it works pretty well. So yes nitrous is FORCED INDUCTION. 400whp is not impossible for n/a but its no walk in the park, many hours and mad amounts of money have been spent trying to reach that goal. more displacement, cams, head work, and compression are what is required and they compliment each other when done right. I mean there are 220+whp d series motors these days so nothing is impossible.

[honduh_head]

lol. 420whp? 400lb/tq? 13s? dude that amount of horsepower will
deff. dip u deep in the twelves with some slicks and any sort of traction bar system.:blunt:

[comptonasskerry]

lol. 420whp? 400lb/tq? 13s? dude that amount of horsepower will

still spending way to much money to only run 12s with slicks.

i would just go b series turbo, cheaper and have more parts out.


but for n/a 400whp is a huge number yes it can be done would u drive it daily no. it would be nice tho to have it and feel that n/a power but just doesnt seem worth it to me. i would much rather go boost and still drive it daily.

just my 2cents

[4G63PWR]

13's on street tires...slicks is a different story!!

we never had a chance to run with slicks, thats what sucks:ballin:

you can use stock k series to make 400 + hp...so it being more expensive is a myth...the Kpro is the only thing that really sets back the K series in cost...

[H22POWERDEG]

Need a K20 Max out build motor, alcohol fuel or nitromethane your choice, and money you dont care about. sums it up :)

[allmotorgsr]

haha yea besides the k itself!!!
and all the bullshit parts necessary to build a reliable k swap.
ive contemplated the cost and dreamt about it many times.
waaayyy outa my budget range......:blunt:

K series parts are actually pretty cheap. I miss my old RSX.

[hawaii_DA6]

i can make 400 with my Honda lawnmower eng.

[sn_halo]

my d15 n/a without nos makes 290whp

[prelude202]

Why is it better? Becuase a 350Z will outperform it in every single category?

Nope. THe S200 is quicker off the line and may I saw ive seen 350Z at Firebird from
AZ350Z and they r pretty slow running high 14's low 15's with performance parts on them.
