is it possible to rebuild my d15 motor to 170hp? or would an engine swap.. maybe a b18? be the best route.

How much money do you have?

Probably cheaper to get a dual cam swap in order to get 170 whp. If you really want to build a single cam, talk to MistaBone.

Hooch'n

Singlecam=Turbo

Cee_mon

you need turbo if you want to see those numbers.

how do you explain bisi's 1.5 na pumping around 270whp i believe. but for the streets, it would be alot of work, most likely force induction. depends how much money you are willing to spend.

its not 270whp...its much less. And i dont think bisi's motor is really "streetable" as its like 14:1 or so compression.

To make 170hp the only really "steetable" and "affordable" setup would be a turbo.

personally id just swap...the d15 is pretty weak. You would be much better off with a d16/turbo or b-series.

I doubt Bisi's engine is only 1.5 liters. Try adding 2-3 tenths.

i run a d15b vtec turbo 172 whp at 8 psi....14.2 1/4 mile..not too bad for a 1.5

SOHC_MShue

nice. what turbo are you runnin?

Zer0DazE

wow, a whole lot of misinformation in this thread....

1. anthony m. : dont post crap about someones engine if you dont know... its actually less than 1.5... not more... try 1.4 give or take a little. and its more than 14:1 cr... thats all irrelivant to the subject though
(no offence, just dont post garbage)
2. some of you butt heads dont get it. the gsr sports a 1.58 r/s the d16 has 1.52 not much of a difference... the d15 with vx rods has a better r/s than a gsr engine. dont hate the d series. (agian irrelivant, just making a point)

andwrong: to answer your q... yes its possible, and it will cost you less than a swap, but its a lot more work and you need to know your *** from a hole in the ground. (again not meant to be taken personally)

go to the d series forum and read man... if you want to build thats where you will find a ton of info, without all the haters.

Just cause you doubt it - doesn't mean it isn't true. Bisi is running a naturally aspirated D15B6 SOHC 1.5L non-VTEC. It's the world's fastest and quickest SOHC Honda - the first non-VTEC naturally aspirated Honda to run 11s and 10s, and the smallest displacement All Motor vehicle to run 10s.

Anyway, 1.5 liter engines have just as much potential as 1.6 liter engines. It's a matter of finding the right ppl to help you. This is who Bisi uses:

i might be making a total *** out of myself, but isn't bisi running like 18:1 CR? i know that sounds rediculous, but thats what ive always heard.....

Zer0DazE

yes, he is running a rediculous high cr... nothing you could run in a street car.

dom93hatch

Where's Mista Bone when you need him?

civicmandx94

I would save all the hassle and go for a swap.

Zeus Zore

i would, an gonna build a killer N/A Sohc.. 2 kick some B16 ***...

cjames235

bisi has 290whp and is running around around 22:1 c/r now.

Chris y0!

where can i get more info on bisi? like pictures and specs? this **** is interesting

JDMs1eeper

their is a guy down here that resleevd his d series to fit stock integra rods and pistons. he did a mini-me this way. he has i/h/e and a port pollish job done by a dremel and he it putting out a lil more then 170whp. he resleeved to 81. yeah.. i know. bad *** mini-me ahe??

that would make it into a d19 with all that stroke an bore wouldnt it?? somewhere around there...

go to the d series forums. he has posted a bunch of info about his setup there

sohc_boy

goto http://www.dseries.org bis posts there often. also his motor is a bored stroked 1.5 not sure on the displacement.

No way in hell theres a NA d-series running 270hp. No way in hell.

Turbo and you'll see 170

I would go with B series...

kommon_sense

don't limit the d-series to your own ignorance. The d-series is a great little engine and with a little knowledge can be made to be a nice little performer. The guy in question Bisi has a heavily modified setup. I know little about the actual details of his engine, but it started out as a d15 and runs 10.77 in the 1/4mi while still NA. Not many people can break into the 10s even with a turboed b-series.

Also, a number of people are pushing 170whp on a d-series NA. So you don't need a turbo to see it, and plenty of people are over 200whp w/turbo.

People keep looking down on the d-series, but you can make a d-series faster than a b-series for less than the cost of the swap.
