Im just wondering what you guys think is the max streetable WHP to have on your FWD honda while keeping it daily driveable... Im thinking about doing a turbo project but i need to set a HP goal. Im not into drag racing or anything and my car is only used on the street. I'd like to have alot of power to use when need be but i dont want to be spinning tires without even trying up to 4th gear. So whats a good WHP goal for a 100% streetable car that would like to eat some bigger cars for lunch? I was thinking somewhere around 300WHP.... Opinions?

 

wanna know also..

 

depends on the car. i drive around on about 350whp/260wtq @15psi in my 99 si. it works well and usually gains traction in 3rd but its a heavy car(for a civic). suspension, tires and an lsd are also a big factor for traction.

 

Well its a 98 ex Coupe. When you say it gains traction in 3rd do you mean its just spinning like crazy from 1 through 3 then it finally hooks up? I just dont want to look like a freak spinning out in all gears from stopsigns and stuff. If your gentle with the gas and dont floor it from the get-go how is the wheelspin?

 

Also i guess wheelspin has alot to do with your turbo selection? Would a smaller quicker spooling turbo give less wheelspin than a bigger laggier turbo? Seeing as its more of a smooth climb.

 

350-375whp

 

for a pure street setup i would stick with 325-350whp...Garrett gt28rs, LSD, traction bars and some sticky tires

 

Thanks guys. Keep the opinions coming

1 Simple question and i think i already know the answer to..... Way better to get this 300-350 WHP goal with a B18b or is it possible with my D16? No need to change motor if i can reach that goal with my D.

a d16 with forged pistons/rods will reach it easily

 

what about a sc34/d16a6 on a 1991 honda crx hf?? how much hp do i need to run low 12's high 11's?? give me a guessamate..

 

It really comes down to the motor, stock vs built ect...

For a reliabel street car, that is still reliable and a street warrior I would say around 325 would be nice. Like I said though it really matters whether your going ot build or go stock. Alot of turbo n00bs think they need tons of power to dominate on the street, but I think we get spoiled with the newest fadam of 500 hp street cars on honda-tech. Fact is a turbo honda with around 300-350 hp will dominate most of it's area with the exception of the Fast domestics and Faster turbo hondas.

I have similar goals to you and my end setup I'd like it to be a Full Ls(current one) stock sleeves, Forged pistons/Rods about 18-19 psi or whatever it takes to make 350/300

Good luck

 

stock block for now..will eventually get eagle rods, srp/cp pistons..

 

I'm running a sleeved stock bore GSR with 8.5:1 CP's, pauter rods, portflow head, ferra oversize valves + springs/retainers, crower turbo cams, an inlinepro mani with an SC61 and a PTE intercooler. Tuned rich by me on the street with a wideband and my AEM @ 18 psi it annihilates my 205 BFG's when warm. I did a 75 MPH flyby in third (around 6500 RPM's) past my buddies shop and then it it, and it spun hard enough to leave black marks on the pavement. You could make out the tread pattern from the BFG's for quite a ways down the street. Rolling onto the freeway if you get on it on the onramp i'll be banging off the rev limiter in third with the speedo reading 90, and then as soon as I let off and the tires stop spinning my actual car speed is like 55. It's a wild ride, but it's still very driveable. As long as you don't feed it alot of throttle you don't make boost, and it drives like a stock car. I can't wait to get the meth going, see how much power I can make on pump gass

Dont threadjack me please lol

As for the motor i want to be safe and will build the block no matter what base i chose. I am thinking a sleeved D16 w/ forged internals should easily support 300WHP seeing thats as high as i want to go. a Sleeved LS engine is more expensive and will pass 300WHP for sure so it might be overkill for me. so built D 300 WHP easy?

 

If easy as in money, than yes.

 

yea i just built up my z6. looking for about 400 whp. stock sleeves
eagle rods
srp pistons
and head built to the max
if i cant get it running right, i wanna hit some mid 11's this sunday
we'll see.........

 

puttin out 360whp @12psi and off the line on street sucks. 3rd gear on is nice. freeway is a blast and rollin on RA1's in a 97 hatch. I'm waiting to get traction bars and lsd and my traction issues should be resolved.

Exactly! With a big turbo its pretty easy to drive around with hitting full boost.

I've got the big T3 .60/.63 on my D16 sol and it doesnt' make too much boost at 1/3 throttle to 1/2 throttle. But damn, once you open it up all the way, it just takes off.

Everyone said this turbo is too big, but drivability is amazing and it spools up great. It pulls HARD to redline too.

You won't even need to sleeve a D16 to run 300whp. With a good tune stock sleeves is all you will need with some forged internals.

 

I think 300 is plenty for the street. When my car was on pump gas low boost it was making right around that and I could pull on pretty much anything. It was way fun to drive, wheelspin wasnt too bad if I went from a roll. As far as turbo size, lag is like traction control for fwd cars..I ran a standard drag 3 kit and it was the perfect turbo for the street.

 

back on the old setup i was running a b18b with a t3/to4b. the larger displacement is good for downlow and the turbo would spool till about 4k. it was quite nice for a daily driver at 8lbs. traction was never there until 3rd, but this was on small 14's.
i upped the boost on the street once to about 11.5 psi. racing a stang on the highway, i was coming around a corner at about 100mph and got back on it. the tires let loose in 5th (gsr tranny). it was quite scary and i estimate about 275 whp (running mid 12's). and i could get traction till almost 4th. so i suggest around 8-12 lbs will be enough for now on a stock block.
you wont be sorry

 

I didnt read anyones post.


You cant make more power than you can control with your suspention. Well you can, but it makes you drive all over the road.

Just a hint.

 

things to consider.
1 runing on the street daily, you have to consider fuel economy.
2 with big power comes a bear of a clutch.
3 it all depends on your idea of comfort VS power.

This is why I'm a lover of big turbos on a FWD street car. With a turbo that fully spools halfway to redline, it allows you to drive comfortably around town in low RPMs. Most people get stock like gasmilage (when driving in low RPM), as well as the nice *** topend...best of both worlds IMO.

With the right suspension/tire/wheel setup, I think around 350whp is about perfect. However, you have to remember that 350whp is not the same on a GSR motor compared to say an LS. The GSR is going to have about 250lb/ft where as the LS would have about 300-350lb/ft...so the driveability would actually be better with the GSR.

My SC50 ZC was awsome on the street at only about 200whp at 9psi. I can say for sure that anything more than 350 would be useless on the street no matter what the suspension. (unless we're talking Highway... )

 

&lt;--260whp and no traction problems in second gear on street tires.. i'd probably manage traction at 300whp with drag radials.. but i can't say until i try.
