hi, I'm brand new to Honda tech. I have a d17a2, and yes I'm sticking with it. I just ordered the crower valve train(stage 2 cam). I was wondering if anyone else had done this already, and what kind of proven gains did they get. I already have full d17a1(dx) exhaust, cold air, clutch and flywheel, solid motor mounts, k20 injectors, and ralco rz pulleys.

Now for all of you out there that are going to tell me to go the the k20 or put my motor choice down, I don't want hear from you. I'm out to prove a point. my buddy spent 14000$(Canadian) on his k20 swap. I've done my research(this is some of it) and I'm GOING to prove to him that the d17 isn't that bad.

Thanks for your opinions.

 

you are going to need some sort of engine management to control the idle with a stage 2 cam. and what do you plan on doing boost or N/A

 

I plan on N/A for now. We'll see later, cause we all know it never ends I plan on doing this over the winter, and i have my eye on the apex1 afc neo. would that thing work? I still have a bit of research to do on that topic.

 

yes, that will work. and the rewards are not that great for the amount of money you are going to put into the d17 to make the power goals you want for NA, i would think about going boost if i were you! much more rewarding for the cost! just a sugestion man.

ya i've heard boosting the d17 is pretty rewarding but i want to try N/A first. just to try and be different. Know what i mean? for everything i'm doing this winter. it'll be about 2600$. for me i don't think thats to bad but we'll see if it stays at that. and if N/A doesn't work out how i want it to, boost it is.

 

man, bomerman19 has done everything possible besides high comp pistons for the d17 and is prob only making 160 whp or so, this includes hondata kpro stage2 cam with springs and retainers, a jdmfabtech custom intake manifold. and others he prob has more then 5 grand into his car and only has that for horsepower. you can buy a turbo kit for 2500 dollars and make 200 whp easy, check your pms

 

thats what everybody tells me. however I find it very hard to believe and no-one ever has any dyno sheet to show me. I'm the kind of guy that needs proof and if I do happen to waste some money in the end so be it. at least i know i tried.
By the way OBXR makes a I/M for the d17. and the valves for a d16y8 fit.

 

post a link of this intake mani, and yes all d16 valves, valve springs and retainers fit the d17, i can send you a link where someone made 124 whp with a stage 1 cam N/A

 

http://www.obxracingsports.com/products.php?pk=1202 thats the link for the I/M

sure
what else did this guy have done? other that the obvious

 

headers intake exhaust. theres not much else for N/A besides internals. building the bottom end, and engine management

 

is there more info on that intake mani?

 

Not true that's just the begining. What about pulleys and flywheel, k20 injectors fit. Pr2 thermal gaskets. While the head is off why not p and p. And do the trottle body too. Disconnect the coolant lines that go to the tb. It all the little thing that make power. My last car was a cavalier. I had a 2.2 ohv pushing 193whp.

 

yes all that stuff is possible and just cost more money and not enough power. you can do all that stuff with boost to to make power and create more power then N/A. i just dont find it practicle to build an N/A d17. not enough reward for the money put in. and oem are the best gaskets to use. and all the other stuff such as pullys and crank are not gonna give you big horsepower gains for the amount of work and money its going to cost you. im not telling you what to do or how to spend your money, im just saying its not practicle to spend the amount of money it will take to do a full N/A build and not make anywhere close to the amount of power you want. the d17 responds horribly to basic bolt ons.

 

I think that manifold is for the ep3 version not em2. I never though there was anyone else that made intake manifolds for our cars besides that fab guy I forget his name.

 

gerry from jdmfabtech

 

i emailed obx about the fitment, they gave me the email of someone else to ask so i emailed them and are waiting for a response. ill keep you guys updated

 

So can somebody explain to me why its sucks so bad?(in detail) why is the d16 better when there almost identical?

 

the d17's intake manifold sucks something awful and is really restrictive. and it was made to be economical. it does not have an adjustable fuel regualter, or a return fuel line for that matter.

 

hes out of the D17 game

 

put a aftermarket y8 intake mani on it. Problem solved.

 

None of them will fit without serious modification to either the manifold or the firewall. The stock y8 manifold barely fits and it still requires a lot of work. You have to do something to adapt the stock TB, the y8 TB doesn't work. Thats the biggest challenge. Then you have to get rid of EGR. It's not as easy as everyone seams to think.

 

then you gotta make mounting tabs on the stock fuel rail, tap the holes for it to mount on the d17. theres a lot of work that goes into it. and the OBX manifold is not for the d17! i had emailed them to check

 

U'll nvr be able to run stage 2 with the afc neo.. U need kpro to make it run right.

Bomerman's car will suprise you. We've estimated 160-170 whp and would've loved to see what it would've put out with the pnp head. It would run with the new si. Well up to around 90-100.

Noone has ever went as far as Paul did on D17 N/A. If you want to, I say ditch the a2 and find urself a natural gas d17, and swap your a2 head on it and go with the stage 3 cam. We think with this setup u could hit almost 200 whp n/a. Only problem is the natural gas motor is hard to find.

I was about to go stage 2 and had the cam and everything lined up to do it, then decided against it and went boost instead and am now currently collecting parts for it. Reason i decided to go boost over stage 2 is for the amount of money it would cost and the power you will see. I say go boost man. U'll love it a lot more in the end. Just my .02

 

jjust my point bryan. thats what i was trynna explain.
