D15B2 230 +/- HP with 35-40Mpg Project

Im probly a big noob and dork to do this but shur why not. :P

Well im starting collage this summer At DADC. During the weekends they allow the student to come in and work on our cars, run them on the Dyno and will help us if we need it.
So Im planing to rebuild my moter with good range hp without scaerficeing gas milage.
It has 280,000 mile range. So i trying to at lease keep it runing till i get to school.

-1st run on the dyno and see where it sits in timeing and runing.

-2nd Looking at my options see what combo of part i can do and priceing.
(DaDc has contact i can order part a little cheeper then buying them from a store. I also check ebay.)

I like to rebuild it to hold a 7-17 +/- psi turbo. Blueprint the motor so it can easly run 8000rpms smoothly. Use forged pistons or some preformance pistions and lightweight crank and rods. Moter Balance polished ports, that all i can think of at this time but i belive there a little more.

-3rd Build it. Since i only can work on this project on the weekends it will take a fiew weeks. In the mean time ill Fix up my ride it need a new paint job, breaks, new Suspension, got to get a sterio sys, Tires and rims, ect ect.(make it look pritty)

-last run on dyno see how mutch of an improvement.

I like the turbo to spool up around 2700rpm. since most my driving it runs areoud 2500-3000rpm range. I like the turbo will engage when ya need to get around someone or something when you need it.

My estmated price of this is about $2800-$4000range. :?

Here are my questons
1. I've hered a turbo could improve gas milage, other say it suxs the gas. ??
2. Will i have to get a new block or will A rehonded/bored stock motor block do.
3. What have you see done to the stock motor and what do you think could work for my project? Let me know.
4. If i cant use my collage resouces and discounts to save $ geting parts what other thing i can do, and what a great moter to swap with?

I like to here what you think of this Post thank.

    I think your price range is pretty reasonable. I would suggest getting a D16A6 from an 88-91 Si as a slightly better platform that can be had for cheap. Then read this thread... http://ef-honda.com/main/viewtopic.php?t=25061
    As you can see, your estimated 230hp can be had fairly easily and dependably. Just be sure your money is in the tune...do not skimp on fuel management.
    With the correct tune and not beating on it ALL the time, gas mileage won't suffer much. Honestly, not even a concern.

    There's another guy on here that has turbo'd his AWD wagon...red civic standard. http://www.hondacivicwagon.com/board/vi ... highlight=
    Those are some good reads. Check out what worked for them...

    I'd say for your budget, you could have a great little turbo SOHC set-up and be very happy with it.

    a) you can have all the power in the world but can't put it to the ground without the rest of the picture. Before even touching the motor i'd do flywheel, clutch, tyres and suspension.

    b) lets be honest, even if you could get the MPG that you are after, will you really drive it lightly? I know i wouldn't if i had that power.. :lol:

    Theres a number of guys on here that are really clued up, as MVM check out Red Civic Standard's build, along with Turbo_Teg and Akiraboy (most likely i've missed others too).

    dont forget brakes too. you'll need somehow to stop all that power.

    your whole plans seems very reasonable. i'm sure if you stick to a smaller turbo you wont hurt the mpg, and it'll spool up a lot quicker too. its all about tuning, and there are many members here who can give you tips on the turbo setup.

    True :P , all others time when im not messin around hopefully i shoud reach that range of milage.

    I thinking on a 4pluck clutch and a lightweight flyweel to help with the extra power.
    Sports breaks a reardisk conversionand and a
    2"-3" suspection drop with a adjustable feature. firm-soft.
    I don't know what brands, but that what i like to get.

    Q: would a 18-20" rims fit on a wagon or will i have to stick around the 15-17" range?

    Stick to 15-16" wheels...especially if you're at all concerned about performance (not to mention it will look better).

    If this is going to be a daily driver too...I would suggest just getting a good Stage 1 clutch. With the clutch you're thinking, it may make toting around town a little more difficult.
    Also, I think lightened flywheel is my favorite mod on an N/A vehicle...but I've seen a lot of guys that prefer stock flywheel on turbo'd set-ups. I'd just look into that first before buying.

    you could get the 18-20" to fit, but you'd have to get the fenders rolled. and as doitdub mentioned, the 15-16" would look better. the car's old remember, so some huge diameter rims would look way out of proportion. i believe 16" are the best choice. a small drop will get those wheel wells filled up nicely. ive got 15" and it still looks too small.

    2-3" drop might be a bit much. if it is a daily driver, slamming it isnt a good idea. and if you're gonna be driving around fast n such, hitting an unexpected pothole will mess up the underside of the wagon, and not to mention the possibility of ruining your struts. and with such a drop, you'll run the tires down a lot faster, if you dont get a camber kit.

    that rear disk brake conversion will be a very good upgrade. talk to mrwagovan about this. he got it done and he's loving it.

    g'luck with the build, do a write up or tkae pics of the progress :D

    Well Since i still time I have been Looking at other options.

    I Like SOHC's east to work on. Great do I want a superstock or a super built VTEC?

    VTEC worth it. better worst ???

    Shoud i build up a stock D15B2?
    16 Valve SOHC
    1493cc
    9.2:1 c.r
    PGM-FI DPFI 92 bhp @6000 6800 rpm 89 lbft @ 4500

    or would it be woth it to get a D16Z6 and build that up?
    16 Valve SOHC VTEC
    1590cc
    9.2:1 c.r
    PGM-FI MPFI 125 bhp @6600 7200 rpm 106 lbft @ 5200

    I like a little guidence and or opinion.

    Honestly, I don't think this is really a question. You'll be happier and have more return with the Z6. Another option when relating to D16Z6, which would keep costs down some, especially if your bottom end is healthy, would be a mini-me (which is a VTEC head such as the Z6 or Y8 slapped onto a non-VTEC block). I loved my non-built mini-me in my last CRX....I beat on that thing all the time and still got great MPG (low 30's).

    There's tons of information out there on the mini-me, but this is what I used to do my research and undertaking...

    I have to disagree here...your wheels + your wagon = total sex

    hahah that's a great way to put it


    i've got to agree with doitdub. to keep the cost minimal, do a mini-me swap. you can still build it up to produce some healthy numbers. but if cost isnt a factor...go for the whole 9 yards.
