okay well i have a d15b7 with nothing done to it yet i was wondering if it possible with a little work done to a z6 or a y8 head if it would make around 200hp at the wheels or would i need to go boost for that

 

Go boost thats the closes way you will reach to 200 whp on that engine.

damn lol i was just tryin to buy something to hold me over till i can afford a b18 i was wondering if say i bore the motor out and i dont think you can stroke a d15 i'm not a big honda person yet so help if wrong. but was wondering what i could expect with say a stage 2 cam and the motor bored out like .030 or so what should i expect for power to be with typical I/H/E upgrades as well though

 

bump would like more help and answers

 

You could boost the b7, but most D-series guys don't recommend it because of it's weak rods. You could buy rods, which are as much as a d16z6, which will easily reach your 200 whp goal. I would not do anything n/a to a b7, it's just not worth it imho. Patience will be your best friend if you're really wanting a b18. N/A my understanding is they are about the best without building. Of course for about the same money, you could swap in the d16z6 and boost it. Just up to you and your goals.

 

Throw an H in it
2500 for the full swap

call it a day

Short of boosting a 1.5 you're not going to get 200 hp out of it. Even then, the 1.5 liter con-rods are like tooth picks and will snap if given half the chance. (check out turbod16.com)

Given a super expensive build - you might be able to (might) make 200 very peaky HP out of a D series engine (I think someone did a d17 crank into a d16a6 engine w/all kinds of machine work, etc. and got somewhere around 200 - look @ aug '07 Honda tuning magazine).

As far as your engine goes, the cheapest thing you can do is an A6 cam (from an 88-91 1.6 l - D16a6) with a 96-2000 1.6l non vtec (d16y7) cam gear & a K&N drop-in this'll get you maybe 5-10 horse (if you ebay the parts this might only cost you $50 + the air filter)

A mini-me vtec head swap (I think this was mentioned in another thread) will get you something like 10-30 hp depending and might run you around $300 for the head, head gasket, and computer.

You can also pick up a 1.6l vtec engine & computer for maybe $600 in good shape, and this is about 30 hp, combine that with the vtec tranny (lower gearing) & the higher redline and you're even faster.

Shave the head before you drop it in and get another couple of ponies.

Building the 1.5 is gonna cost more than any of those with questionable returns - no where near 200 hp, and no reliability at all - if you need 200 HP, get a vtec B-series and work from there - it'll be cheaper than trying to make a 1.5l d-series do that.

Hope all of that helps... anyone else feel free to correct me if you feel I'm way off base.

 

instead of wasting all that time, money, sweat and blood on working on the d15, save a little more and go with the b18 swap you want.

 

Its expensive enough to get a B-series to reach 200whp N/A, but a D-series....good luck with alll that.

 

200whp from a z6/y8 on boost is possible, and without having to go crazy. Tho, It does require proper parts, installation and tuning time.

 

Boosted single cam

posts like this don't make any sense to me. what you basically ask is this: "how can i spend my money on my existing engine while i am in the process of saving my money to buy a different engine?" it should immediately strike you that your logic sucks. if you are saving your money for something, then save it. if you dump your money into the d15, it will just go to waste because you will be using a different engine "once you can afford it." you will obviously be able to afford it sooner if you don't put money into your current motor. just accept the d15b7's shortcomings and save until you can get the b18. use your head.

 

I second that. But would like to add: Shop around for a LS swap. Check local junkyards. There's a few junkyards by me that are littered with 90-93 integras with the motors & Tran's still in them. You have to pull the motor yourself, but it'll only set you back about $450. Once you get your motor and tran's, start building it or shop for the necessary parts to adapt it to your ride.

totally agree. to make 200whp on a D series without being a fix-every-day setup, you will spend more than the cost of a B18 swap. Much more.


Either **** or get off the crapper, man.

 

200whp with a d15b7 and "a little work"

 

The only cost-effective method of making 200whp on a D series is by way of a turbo setup. Stock internal D's are good to about 220-240whp on a good tune. If you want more than that, i would suggest an Eagle/Vitara build which can sustain ~400whp.

 

so yea someone says something differnt about this task would it be hard for it to even acheive 150 whp.

 

NA? Absolutely, they're correct.. It'll cost at least $2,000 to get any sort of near 130WHP

 

bump want more opinons

 

not even worht it dude.i have the same motor on a 93 hatch and i have read more than enough threads to convince me that im better off gettin a new motor.and working from there.its all about patience!

 

so yea basically not even worth doin the mini me swap wit a z6 head and what not cause i figured buy a mini me and what not and then after i bought that then buy a trans and clutch and what not for the car since i need 2 switch to a manual

 

A healthy z6 swap, i/h/e, and expect low 15s high 14s at best, in a hatch. Stg 2 or more cam and you'll be mid 14s putting down anywhere from 130-145whp on that setup. From there you can change out the pistons for ZC's and run 91 octane, get engine management, tune it, and gain some more, but by then you've spent enough money for a b16a swap with labor, or a b18c swap without labor.

So you can make more power for less dough with a mild NA D16Z6 build than a B16 would make stock. But think about it, the B16 hasn't even gotten started yet, and that motor will yeild 200whp alot easier, didn't say it would be easy, but at least it would be streetable. That's what I wanna build someday...

I'm enjoying my i/h/e d16z6 right now though, it's as quick as my JDM H22A BB4 Auto was, but I guess that's not saying a whole lot. Building a single cam is fun, just don't spend alot on a header (SMSP/Bisimoto) if you're pretty sure you'll have a different motor in the future.

wow, a d-series can easily reach 200 HP.
in my opinion heres wut u should do if u want quick power.

alright. just so u know ur runnin around with about 98Hp right now.

so wut i would do is put a Z6 or Y8 head Mini me conversion(i happen to have everything fo the swap myself, lemme know if ur interested) then boost it and u'll make around 185hp. HUGE difference not to mention the extra 50 or so LBS of TOrque.
now i'll tell u how. this is gonna cost about 300-600$ for the turbo stuff. by as many used turbo parts as possible. get a dsm turbo, the HF manifold with the adaptor plate already welded on, an FMU, an ebay intercooler kit with BOV, and try to find a cheap used downpipe. run about 7 Psi. the Y8 head is optional. it will help u a lot to get to ur goal.Lmk if u have any questions. this was my brothers old setup. its great, and cheap and even better if ur just using it to hold u over until the b18. then wen ur done with it sell it to some1 else and make almost all of ur money back.
