170whp??

[futurerexer]

What's the cheapest way to get to 170 whp?  I am thinking a b16 with I/H/E.  What other bolt ons could be used to achieve this number?  I like boost but I think all motor is better and more reliable.  Is there another motor that would be better, or is the B16 the best choice?

[Turk89si]

CHEAPEST WAY would be like zc with a 50 shot. but i wouldnt go that route on a stock zc even thought its only 50.

[5gencivic]

cheapest... that would be a zc with a small turbo or supercharger. that'd do it... but the cheapest reliable way would be b16 with i/h/e and some itr cams. that'd be the easiest way prolly... :mmkay:

[Phiber Optic]

b16 with light mods if you wanna beat the shit out of it all the time, and not worry too much about hurting the motor.

zc turbo if you want a cruiser and a weekend race champ for sudden speed cravings.

hard to tell which would be more expensive though, zc turbo might be a bit cheaper

I don't think you can get about 40 whp out of an I/H/E setup with the B16a.  Are you looking for dyno proven hp for bragging rights or something that just kicks ass?  Where did 170 whp come from?  I'm just curious about that.  

I would go B16a and do what 5gen said.  ITR cams are expensive but WELL worth the money.  With an I/H/E setup and ITR or CTR cams (a mix of the two is supposivly the best) you would probaly be close.  You could even raise the CR but I would watch out for detonation there.

Understanding the driver and such, I am thinking 170whp will get me around 14.0.  Maybe even into the 13's.  And yes, I like to be able to drive the shit out of it.  B16 sounds best huh?

ITR cams are no where near the best for the B16.  I think you can get that with a B16 and bolt ons.  But included un my list of bolt ons are Intake, Header, Exhaust, TB, IM, Cam gears, Lighter pulleys.  

And plus man, you have to remember stuff that will make you quicker ( in other words make you faster but not make hp) like a short shifter and tires.  Stuff like that.

This is what I've heard (not seen or proven).  The B16a responds very well to one ITR cam and one CTR cam.  I can't remember which one goes where (exhaust or intake).  I'll look into it when I can.

[masta shark]

you need a LOT of mods to make 170whp on a b16...

the itr and ctr cams are almost identical, except the CTR intake cam has a slightly longer duration, or maybe a little higher lift..or err, i fuckin forget, i havent thought about honda's in months

From stock, you need to make 35WHP to get to 170WHP. FWD cars tend to have a 15% hp loss from Fly--> wheels, so you'd need to make about 43HP or so additional to the 160 to get 170whp....

I/H/E  14 or so, if that
Cams/Cam gears, tuned  12-20 depends on the cams
Intake manifold, TB 10-18 or so, depending on the shit you buy

[steel]

It can be done, so there ya go man.

you dont lose a certain percentage of your horsepower through the tranny and drivetrain. its a fixed number that goes up slowly when you add more horsepower. thats just a common misconseption.

CTR intake and ITR exhaust are the cheapest cams you can get that will increase your hp. also if you have the money look into skunk2 cams.

oh and dont think cause you have 170whp that you will run 14.0's, sometimes when you create more horsepower you have to learn how to launch the car and shift points all over again.

I don't mean to be an anal dick here (anal dick, that's a new one) but how can a fixed number increase?  If it's not a percentage, what is it?  The only way I've ever heard of figuring out the difference between whp and hp at the flywheel is the percentage method.  Of course you could believe the factory specs and imagine that your 2002 Sentra SE-R really does have 165 hp.  Or the Miata, remember when that hp increase they did a couple of years back actually brought the car up a whopping 0 hp?  What about the SVT Cobra?  The new ones had nowhere NEAR what was advertised until last year.  Of course the VW GTi turns the dyno rollers at the same hp that the factory says is at the flywheel!  I don't believe ny of it unless I see a dyno sheet.

So does anyone have the dyno figures for a stock B16a in a CRX?

[silverkorn]

i knew this was going to come, and here is the reason why. now when you have the tranny certain hp gets lost in making those parts move and the weight of each item. now if you increase the amount of hp created by the car at the flywheel, those parts in the tranny and drivetrain will not ever change the weight or the amount of resistance against the engine it has. yes the amount of lost hp will increase when you add more hp to the engine but it will only go up a few.

now lets say you have a stock b16 swap.
160hp at the fly and going by the 15% loss figure you get a loss of 24hp and giving you a total of 136whp.

now if you boost that car to holy hell and get lets say 350hp at the flywheel. you will still have only a 24hp loss from the tranny plus/minus maybe about 5hp. so lets say an even 30hp loss. so now the whp is 320, which is only a 9% loss of hp from the tranny.

i thought 160 is already figured to the wheels on a b16
