From a racer's standpoint, a billet cam would be a good choice if willing to pay for the price.
From a business person's standpoint, its not cheap to manufacture a custom billet camshaft for the d17 but would be a good thing to sell since there really isnt a choice for camshafts for the d17.
From a tuner/designer's viewpoint, it would take quite a bit of time and money to actually develop something for the D17 that will work perfectly for the General public.
Let's say we had the time and funds to do the full R&D of developing a camshaft, being a small company and not having thousands of dollars to waste, another company can easily copy our camshaft design and our return on investment will be minimal. Thats my reason to not design for a Billet camshaft. We are planning to possibly do grinds for the D17 but give us some time to see what we can do with the D17 cam. Liek I said in other posts, we have several D17 cores and will start R&D on some grinds soon.

wussup guys,
sorry for the late reply. its been a tough spring for us with all the events we are going to out of state.
and keeping up with the business. we are geared for sleeving and headwork right now for the d17.
Unfortunately, time for more R&D such as high power turbo system and extensive cam design is hard to get to at this time.
Just being honest here that its not going to be easy and quick to get things for the D17 head.
but liek i said. Block work and head work we can do now. that is no problem.

at this time, just the headwork and block work. we can do match porting on TB and manifold and head.
thats it at this time... no BS claims here.

As long as you take it easy on the boost, it should be fine. Porting the engine just allows more and better airflow through the engine. It's not major work but can yield good gains if done properly.

Rep Power: 322 Getting a good grind on a cam would be great. I would buy one in a second especially if you have cores already. I was going to find a core and send it to crower to grind, but I can't come across any good used ones. I am sure they would just increase the dur. and lift a bit over stock. I am wondering now if I should just wait for the R&D work to be done.

ok if a billet cam is to expensive to make then why not just develop a forged steel cam. We need cams !!!! (just do a search and see how many members inquired about performance cams) Being a small company, if well developed, having a good production cam for sale could get your name (www.exospeed.com) in the market!

Rep Power: 811 ust a question. Will milling the top portion of the head by 1mm cause any problems with respect to cam and ignition timing? Stock is 0.2mm. Also, what will having ports that are completely smooth do for gains?

Rep Power: 322 cam timing yes, you will need a cam gear and adjust it. there is a formula so many degrees for so much material taken off, but I don't know it. The honda-tech guys would know.
super smooth exhaust ports are good but you want your intake ports to be slightly unfinished.

Rep Power: 811 So I need an aftermarket cam gear, or can a tuner adjust the stock one? 1mm milling sounds like it would change the compression alot.

Rep Power: 322 you can bet that the compression will rise. I don't think anyone has raised th comp ratio yet. I wonder what the ecu will do.You will need an adjustable cam gear. the stock one wont adjust.

Rep Power: 811 Well, I'm asking because the DH ported head is milled 1mm. I'm checking on it to make sure. Would I be able to drive it without tuning until I can get to a dyno and have them set the vafc and cam gear?

Rep Power: 811 Okay, I'm gonna find out for sure soon. All I know is another member that got the DH head said it was milled 1mm over stock, which is ALOT considering it was for a turbo app.

hey how much would it be to get my head pnp, rods, pistons and sleeved.. i dont have all the money but if u give me a descent price i will be very intrested.. thanks

for blocks, we can do full sleeved blocks with upgraded pistons and rods. full rebuilds.
if the board is down for it, we can do a Group buy on block work. We don't really stock d17 parts since its not a big market yet, but if we do get a good number of people, we can extend a discount for the group purchase.
on the Cam development issue: its not so easy to do R&D on a new cam since we are already swamped to begin with. we are enthusiastic about the d17 motor but honestly, with the racing season and the current workload, its a challenge to do the R&D at this time.
as far as head milling. we dont mill any of our heads at all since we dont believe its a good way to really make HP. yes its a cheaper way to increase compression, but in the long run, we rather focus on head flow and piston design to make power.
If a customer asks for a slight mill, we can do that if desired.
Overall.. we do what you want us to do. We will complete work to your specs and application.

Correct. Rigid intake ports create turbulence in the air flow, which in turn creates better cumbustion in the chambers.
