D16y8

[civicrunner]

Ok guys throw your advice at me. d16y8 (auto) i/h/e so far. and some other stuff like drop, rims, bla bla bla. I plan on going turbo. What other enging mods would yall reccommend to build major hp and tq? Thanks!

Major HP and Torque on a D series engine do not fall under the same category. You wont expect to see much gains from a D series motor. Swap would be your best bet then turbo to get that much gain.

[GScivic7]

sell your intake and header, and save up for either the Greddy or Edelbrock D-series kits. It's the best way to start off if you want to go turbo. They don't offer a ton of power, but they are complete kits that are more or less bolt on.

it's not really worth it to turbo a d-series engine though, you can't get a lot of power out of them like the b or h-series. unless you do some major internal work and such. good luck though. save up for a swap.

Shows what you know... I'd read up LOTS on D-series motors before making a false statement like that if I were you. A character on the IDRA (maybe it's NIRA) circuit (Bisi E.) used to have the worlds fastest ALL MOTOR SOHC D-series, which could run 10's and circles around most other import drag cars in the N/A catagory. He retired the motor in favor of a SOHC F22 series motor which he's kept N/A as well, and is running even faster times with.

I've seen D15's (NOT D16, but D15) that could push out 220whp on a dyno, (cam, P&P and a 50 shot of nitrous) and all on STOCK internals. That's about the maximum though before rods are snapped, and crank is scored. But that's enough power to put an ITR, or even CTR in the dust. Also dollar for dollar, it's been proven that for the price of a B-swap, a D can be built to have the same amount of power, and perform just as fast if not quicker! Don't believe me? Read up for yourself here.

Civicrunner, I'd talk to www.deltacam.com and get a 262 grind or 272 grind cam from them. Under $100 (you ship them you're current cam, and they send you a re-grind core back to install) and you're looking at a nice 10-15hp gain at the wheels just from that alone! 262 grind is good for about 10hp, and 272 is for about 15hp. Both cost the same, but if you go 272 grind, you better get some stiffer and better valve springs and retainers so that you don't get any valve float. I'd also highly look into the Edelbrock turbo kit as well. Seems to be the best and most power kit on the market right now.

Link doesent work for me. But anyways, let me re-word my first post then. You wont expect to see much gains from a D series motor compared to a B-series, K-series, or H-series.

You're still incorrect. I said above that a D can MATCH the gains of a B, K or H series motor. That's pretty sizeable unless 100+hp gain isn't much to you, which is essentially almost double the normal output of a D-motor. Yes, a D cannot peak near as high as a B, K or H, but it can be increased to OVER 4 times it's original factory rating. Again, I advise you look this info up before spatting out incorrect information.

BTW, till the new site is up and running soon, you gotta register onto the site in the link to be able to browse any of the info on it. Obviously you aren't reading...

And lastly I ask you, do you have much if any experience with D-motors, or are are you going off pure assumption and think that because it's a factory econo motor, then swap is the only answer...

My apologies then.

And yes I was under the assumption that...

Again my apologies for any incorrect information I may have given.

And I was also under the assumption that since its an economy car, that the civic was not meant to be fast unless you swap in a performance motor in it such as those of the B-series, K-series, or H-series.

Last assumption too was that you can make a D-series motor fast but with a lot of money.

Hey dude thanks a whole lot! I knew my D series could get some pretty major gains. I just wasnt sure what exactly i needed. I planned on doing some major engine work to build hp, but I wasnt sure what EXACTLY i needed to do. Thanks again!

P.S. I forgot to add. This cam will work well with turbo correct?

Yes, for turbo, get the 272 cam. I know the guy that actually created the profile of it for Delta Cam.

Just trying to put some myths about the D to rest...

As for cost, it's only cheaper till you need to do stuff like sleeve the block, or want to crank the power past say 250hp N/A. Then you'll need to start dumping the serious money in. But compared to buying a B motor (170hp) and boosting it to 200hp, doing the same with a D can/will cost less.

When we will I need to sleeve the block? Is that only after I play with my compression? Is there any other major engine work i could do? Money is not a huge factor, I would really like to build up my D so as to prove to others that they are capable. THanks!

[GScivic7]

basic internal block work for a boosted motor would be forged pistons and rods and resleeving the cylinders. I'd recommend you do these things before upping the boost.

Agreed, you can't boost a Civic more than 8-9psi before you begin to break internal parts...

[civicrunner]

Also one more question. Do I need to get that cam and the turbo at the same time? I heard that if you get a turbo cam and not have turbo then you could actually lose power. Is that true?
