What do you believe would the maximum horse-power increase on a d-series with HIE, fuel rail/pump, and maybe a chipped ecu?

AEM cold air, DC 4-2-1, Buddy club exhaust is what I'm thinking.

I need a project on my car for school and turbo is looking too expensive, and I'm not sure about how I feel about turbo'ing anyway.

Knowledgeable answers will be graciously appreciated.

 

im doing a mini me swap to my car right now its pain in the *** but a good learning experience at the same time if i wanna do another motor swap down the road

 

Which engine are we talking about here?

 

What are the details?

 

D-16 in an EX 98'

I have around $1,000 to spend on this project, and I'm up for just about anything.

Aside from painting my entire car.

 

With such a limited budget, I would go for a junkyard turbo setup. Additionally, shave as much weight off the car as possible.

Make sure that you consider all options with part selection. If it is cheaper to buy a (reliable) component, buy it. If it is cheaper to fabricate it without spending too much time, then do so.

How will the car be used? Drag, autocross, etc.?

 

Junk yard turbo, heh, I would blow up my engine.

The project is not strictly turbo, any kind of work.

 

If you can find somebody to tune the car, you can have a junkyard turbo setup running low boost for under a grand. It would be a much more cost-effective option than spending $700 on bolt-ons.

Again, we really can't advise you well until you disclose the details of the project. How will the car be evaluated?

 

Assuming that your EX has the stock engine (D16Y8), you will likely be pushing about 5hp more than stock, to the crank. Not a very substantial increase, but D-series engines don't respond particularly well to bolt-on parts (unlike the K-series). A new fuel rail and pump would be pointless at this point, so save your money.

 

I don't have a d16y8, but visit d-series.org. The info on there helped me build a cost effective d15b.

 

^^^agree!!

If you plan to do anything with a d-series, turbocharged and supercharged are the ways to go. Don't waste money on boltons for the 5-10HP gain. Save your money and get some kind of plan of where your going with all this(turbo, NA, etc?)

 

Okay, I know d-series are less responsive to bolt ons, but I know an new header, high flow exhaust, and aem intake will make AT LEAST 15.

5-10 for each.

But it is definitely starting to sound like a waste of money at this point.

Guess its a swap or turbo...

 

I'm sorry man, but it just won't.

 

You guess right! search for motor options and pricing. and turbo setups with a budget, GL!

 

they definitely wouldnt make those kind of gains...you will gain 5 hp at the most with bolt ons on a d series

 

You can't do:

5 hp for an intake
+ 5 hp for a header
+ 5 hp for an exhaust
-----------------------------
15 hp total

Each component will affect a different part of the VE curve. Some of the gains might be superimposed, but you cannot add up the gains in peak power like that.

Honestly, it sounds like you need to do a lot more research. I think some of that $1000 should go to decent books on engines.

Also, you're STILL not answering my question: how will be car be evaluated?

 

swap it or boost it, end of story.

 

if you get it tuned you wont blow it up! go turbo and it should cost you in total 2k... thats a s100 Hondata, tune, turbo, mani, fmic, bov, wastegate, and a fmic! done!

 

For 1000$ you could get a swap or boost that would run surprisingly well if you do your homework properly. Whih is the point of this project right? to do your research and build something good on a budget. I would personnally go for a mild swap like a cheap B series motor... doesn't have to be a b16 but maybe something from an acura. You'd be surprised how cheap some of them go for. Or you could build your own turbo for under 1000$ but make sure you get it tuned properly... that is they key with budget turbo builds. Good luck! It should be a fun project either way.

 

Hey, let's think about this a little.

For sake of conversation let's say the little motor puts out a whopping 130hp stock.
Gains could be as much as 13hp. (I said could)

So I think a 10% increase from bolt-ons is worth $5 -800 bucks. + you have spiffed up the engine bay and have a feeling of accomplishment.

You will feel a 10% increase in power believe me! I say go for it!

While you got all that stuff out, it would be a great time to clean it up too!!

 

I'm aware that its not as simple as that math, it was a very rough estimate, but now I understand the limited influence of bolt-ons on a d-series. THANK YOU.

As for books, that's not a bad idea at all. Any recommendations? THANK YOU.

And "how will be car be evaluated" I'm not sure, Perhaps a Dyno before and after.

I would like to do an LS B18 swap which would be a perfect base for an eventual turbo, but also a small step up from a D when left N/A for a while.

I just don't think $1000 is going to cover that swap. ESPECIALLY when everyone says buy from HMO. (I am aware of their quality and helpfulness, they're just over priced.)

 

hahahahahahahaha, u wont make 15 hp lmao, lol. boosting is not a waste of money most power for dollar

 

kinda off topic here, and sorry to hijack the thread, but do you think aftermarket intake manifold/header/exhaust/cold air would help mileage any??

 

That's been recognized. I didn't say boosting was a waste of money, learn to read.

Ohhh, I completely misunderstood your first post. When you said "project on my car for school", I thought you meant this was for a research project. My bad.
