i posted a similar post in the forced induction section becuase i have no completely decided the direction i would like to go with my build. your imput would be appreicated

Re: what i need for a reliable 250whp out of my b18c1 (99jdem18L)
 

if your just looking for numbers
and specifically want 250 hp

go turbo

NA is too expensive, and pushing those numbers out of a C1, I wouldn't call "reliable"

Re: what i need for a reliable 250whp out of my b18c1 (99jdem18L)
 

You do not need 250whp to hit 13's.

How bout a stroker kit?
250WHP wouldnt be a streetable car and wouldnt be fun to drive

for the original poster: what 185+whp hondas have you had the chance to drive? I ask this because sometimes you dont need more power to go faster... https://honda-tech.com/forums/images/smilies/emthup.gif

i hit 13s in my hatch with a stock jdm itr motor, and that was the funnest car i have ever driven...... mild build up on the gsr would hit 13s, 250 whp is extreme all motor, some of the guys running 11s are makin 240+

Re: what i need for a reliable 250whp out of my b18c1 (99jdem18L)
 

lol, wow lots of turbo support here in all motor https://honda-tech.com/forums/images/smilies/emthup.gif im so undecided myself on going na/turbo (n/a motor is finished) i don't know about you, but if i went turbo though i know for sure i'd want more than 250.. https://honda-tech.com/forums/images...s/emsmilep.gif

There is a couple gsr's with bolt on drag turbo kits, tuned with hondata, on slicks running high 12's at low boost/stock block. I've owned a turbo'd car....and it was the most reliable car that I've ever owned. Go turbo for the dollar amount, but remember...tuning is everything. https://honda-tech.com/forums/images/smilies/emthup.gif

Let's say resleeved 84.5 mm bore, cr 12.5:1, pistons, rods, everything balanced, head work, valve train, stage 2 cams, good header and intake and hondata with good tuning. Maybe 240 whp. But why wouldn't it be relaible ??

Because no tuned engine is really reliable https://honda-tech.com/forums/images/smilies/emwink.gif If You want to hit those numbers n/a and want oem reliability &gt; K-series.

240whp b-series will be very expensive.. 12,5:1 is allright on our fuel here rev.. but I think in the states it won't be very easy to get some decent fuel like our 98 pumpgas at every pump :D *yeah baby!*

Even so.. I think hitting 240whp with that setup will be hard... very hard at 12,5:1 ... -&gt; $$$

I saw a guy with a GSR in a mag quite a while ago that hit 12.9 n/a and he was pushin 205whp, it doesn't take as much n/a hp to hit good numbers at the track.

Re: (sti99civicsi)
 

12.9 ??? You mean 11.9 or is terrible slow !!!!!

Hahaha what up twiet ????

But i was hoping for some usa input hahaha. Because i don't agree.

I don't think a fully built gsr at 12.5:1 cr is not relaible. provided you have 94 octane at the pump and some good hondata tuning.

Please explain why it would not be relaible.

Re: (rev limiter)
 

250whp...LOL your going to spend a fortune on trying to even hit that. The setup you have now will have to change as far as headers and exhaust. Good luck, but that much WHP is not going to be reliable.

Suggestions on Header* Hytech, Toda, AN-r
Exhaust* which ever free flowing one you want it just needs to be 2.5 inch or bigger if you shoot for the 250whp.

maybe your definition of reliable is different from mine
What do I consider reliable? reliable to me is an engine lasting 100k miles without having to replace major parts.

Re: what i need for a reliable 250whp out of my b18c1 (99jdem18L)
 

250whp NA? Better start with a K20 if you want to be reliable IMO.

Re: what i need for a reliable 250whp out of my b18c1 (Dan GSR)
 

Okee how about a 235-240 whp setup which has to last 50k miles. That is relaible enough for me. I think that must be possible.

Re: what i need for a reliable 250whp out of my b18c1 (rev limiter)
 

gettin 240 whp is still hard man, n/a power is so much harder on a motor then turbo power...... something to think about. and also i know guys running 220-240 whp and they still have to replace stuff, and its not as comfy to drive those cars as one would think

Re: what i need for a reliable 250whp out of my b18c1 (eddiecut)
 

Define 'stuff' please.

Re: what i need for a reliable 250whp out of my b18c1 (rev limiter)
 

reatainers and timing belts wear faster with big cams

Re: what i need for a reliable 250whp out of my b18c1 (Dan GSR)
 

Isn't 250 a bit rediculous for a FWD car?

You really don't need 250 to hit 13's man.

You should check some swaps people have done on HT. You can hit 13's in a honda with less horsepower than you would think. Especially N/A

good luck with the car

If you want 250 though, i would go with a turbo set for economic reasons https://honda-tech.com/forums/images/smilies/emwink.gif

Re: what i need for a reliable 250whp out of my b18c1 (texasnick)
 

180whp-200whp should be able to crack 13s even run deep depending on the chassis https://honda-tech.com/forums/images/smilies/emthup.gif
