I've got a 1999 Civic Ex, 1.6L SOHC Vtec D-series. I used the search option but couldn't find anything about compatible upgradable heads. Does anyone have any insight or experience as to what makes a good combination head for my car or does such a thing not exhist. I'll probably get flamed for this question but I NEED TO KNOW. Please help.

Just turbo your bone stock Y8 motor. You won't regret it, trust me.

DPR001

Really!? No other head that fits... huh. Well, I'll do with what I got then. Port&Polish and milled you say? Sounds like a plan... only... what's "milled" mean? Sorry, still quite new to the scene. Thanks for your insight though, much appreciated.

integraXTC

do the edelbrock turbo, the most complete system on the market.

Kyles ej1

milled means they shave off a little of the bottom of the cylinder head to raise compression and gain power

edit and get that edlebrock turbo^^^

EX-T

milling the head raises the compression ratio by making the combustion chamber smaller therefore increasing power.

turbo your motor...

DPR001

Turbo he says?... I've always wanted to own a boosted car. The stock motor will take it? Not much psi though right. I'd say like 6-8psi at most, am I correct? What turbo setup would you recommend? Greddy? But you wouldn't want to raise the compression ratio for a turbo though would you. It's better to run like an 8.5:1 compression ratio or something around that. I'm sorry, I'm dumb when it comes to boosting a motor. I have questions and no one but you guys to answer them for me... sorry.

Usually its the VTEC head that's an upgrade for the non-vtec motors that came in the 91 and older civic/crx models. You've just been looking for the wrong thing. There isnt somehting like an LSVTEC you can do with a d-series. Turn your research over to forced induction. Like the last dude said, edelbrock turbo

Kyles ej1

stock internals can handle 9 psi but the edelbrock is set at 7 on pump gas

DPR001

You guys rock! thank you so much. So, I have a 91 civic Lx, I can drop an ls/Vtec combo in that and it would haul sweet *** with mild modifications? So turbo is the way to go with the 99, huh? Yeah I'm gonna start my boosting research and check out that Edelbrock system (performer X, right?) Cool. What about sleeving and stuff like that? Is that necessary, would it help a lot? And will the OEM head gasket take it or should I go with a copper head gasket?

integraXTC

from monster chevelle to civic, huh?

Umm, I don't know about the gasket ****, but the system is supposed to be for a stock engine and it will give you 170hp at the wheels. Pretty sweet.

Not sure really, I guess it was after I drove a buddy of mine's 99 Civic Si Coupe. It was fun and quite fast for a four cylinder, so I guess I took a liking to Honda specificly. Don't get me wrong, I love the sound of a big block but it's just amazing how much power you can put out of a 4 cylinder and how fast they are when dropped in the right car with the right setup.


Only 170 hp? Oh, well I'm looking for a little more than that... somewhere around 250-300whp with some minor internal/external modifications. I have a friend at Turbonetics that can get me some good deals. I just need some ideas as to what kind of setup I need to run. I'm new at the Honda engine stuff, help me out if you can.

Calvinator

I've heard that the d16z6 head is the best because of the bigger combustion chamber, which is probably better for turbo and not n/a because of the lower compression.

electric-boost

honestly I would rather swap in a ls and down the road turbo it than just boost the d-series. The only thing good about the d-series is that they are cheap to replace!!
dont buy a turbo kit, do some research and go to homemadeturbo.com and save yourself a goor amount of money.

Civic4less

Why not just swap out the Engine(Just Wondering) ? Not saying the D-Series is weak or anything but it sounds like you have enough money and you could most likely get more HP with a swap since you want more power. Then you could just boost that? But hey... w/e u want!

boostincoupe

Honestly kid, if I were you - get a used 92-95 civic greddy turbo kit (it'll fit your 99 fine, I have one on my 97 EX), bolt it up to your bone stock motor, and boost around 7-8 psi. You can't just go from 100whp to 300whp, seriously. The greddy turbo is good to 250-260whp, and the new 96-00 greddy turbo kit is good for up to 300whp.

It's obvious you have a lot of learning to do about turbos, so I suggest reading up on this forum for at least a month before buying anything.

blaster834

yup turbo time for you

yeah but are the internals good for that power? idk if I can see those rods holding that much for to long, I guess anything is possible with a good tune

spyderracing

Rods are good for about 220? Correct me if I'm wrong.

10 psi should net you about 200 hp tho.

electric-boost

yeah, thats why you should swap in a ls and boost it to 10psi. you will be happy!

Go to TurboD16.com and read up. people pull crazy power out of there D-motors on stock internals. A guy on Turbod16 named BeerBong runs 10psi daily on stock internals, tuned with Uberdata, pieced together his own "kit", he's making around 220hp. I believe he is also an H-T member.Nice setup.

using the cheapest cheapest prices for arguement's sake.
ls swap = 1200
turbo kit = 1500
2700


forge pistons and rods = 800
turbo kit = 1500
uberdata tune = 250
2550.
mad boost, has vtec, and save money.

so why LS swap and boost? when you can get a nasty D for cheaper?


To the origanal postee.
You dont need a head swap, your motor is prefectly fine.
Is there hope for a faster D-series? you can do whatever you want with money. D-series has more then enough potential for most street cars. I mean if 300++whp on stock sleeves shows not enough potential for you, then by all means, swap out that D-series. Just let me know when you sell your motor, i like to collect em.

http://www.turbod16.com, if you have a d, and u want to turbo it, go there, there is one member with just forged internals and a good tune, 425whp, even stock head bolts. Stock internals are good for about 250whp for a 1/4, id say 200-220whp max for daily driver.
