im not putting turbo on the car but,how much money does the mpfi swap cost?(aprox) i have been looking into it just cant decide if its a good idea since i cant take this car to the states when i leave here.(euro spec) and time because i only have this 1 car and i need it quite often because i got to go see my girl and taxis are hella exspensive here.

- remove butterfly plate (not throttle plate) inside of the tb and the v-plate from the round DPFI black housing
- stick intake filter right onto DPFI housing, don't bother with tubes, even short rams, they just make it harder for the DPFI to grab air

You'll feel a slight difference (especially merging on highways) and will gain some low end just by doing those two mods to the air deprived dual point, and it should only take 5 minutes and $30 (air filter). Although you might aswell go MPFI.

Wait, the butterfly plate? When you take the throttle body apart is that the very top plate that rotates? What are the effects of doing that? Anything bad?

None that I know of. It just adjusts your idle when the motor is cold, you might actually get better idle like I did. More info here:

</TD></TR></TABLE> this sounds like a plan, but theres drawbacks...i wouldnt go there...aside from that id probly say think hard before u do anything else... judging by what u said u use it for and how often, u might wanna just leave it alone if its running ok now......what kinda of exhaust is on it?

i got some garbage ebay 4-1 headers and straight pipe then an ebay muffler but i only have the back preasure from the bends in the pipe,i may buy a better muffler to try for a little more back preasure.im sure a "real" set of headers would help some but these havnt gave me any problems yet for 50$.i've had them about 8months.yeah it runs great as daily driver and having fun on the backroads but ill look into that plate in the TB.

MPFI DOESNT REALLY INCREASE POWER BY ALOT BUT IT GIVES YOU A BETTER PLATFORM ....

NOT REALLY..WHY DO U THINK A BETTER HEADER WILL HELP YOU? YOU HAVE A PIECE OF **** DPFI D15B..IF YOU WANT MORE POWER TURBO IT..STOP BULLSHITING ,,THE INTAKE,HEADER,EXHAUST,INTAKE MANIFOLD,ETC WONT REALLY HELP......IT FEELS FASTER CAUSE YOU'RE MAKING NOISE BUT YOU'RE NOT REALLY MOVING ANYWHERE...OK MAYBE YOU GAINED 5WHP..WOW

DO MPFI AND TURBO OR MPFI AND NITROUS ..CHECK OUT HOMEMADETURBO.COM FOR WAYS TO DO IT PRETTY CHEAP

If you are planning to sell a car, but wanna have a few more months of fun, would you turbo it? No. Waste of money. MPFI swap it and end there. MPFI is about 10hp gain, which almost makes it a D16A6 (108hp) power wise. Or you could swap the A6 in there and MPFI your car and have the A6 torque (a tad more) or SOHC ZC (120hp) or DOHC ZC (130hp). Cheap, easy, makes alot more power.

IM NOT WRONG,,i did dyno before and after on a DX D15b2 made 77whp before mpfi and 81whp after mpfi.......if you call that a big gain then you're retarded...

But like i said it is worth doing gives you a better platform and better mpg,better for performance..

Ill say it again homemadeturbo is the best thing you can do if you want power

dude if you scroll up you will notice i said im not turboing it and nitros is a total waste of money on a car,im not into driving where you could use nitros anyways.the ZC swap would be only 1 i would do because why do all the work of a swap for 10HP?even though it is a much better platform.

Yes it gives you a better platform but there is a noticeable power increase. Maybe its just me but when I did mine I used all Y8 parts and I went from driving slowly up a 2 mile uphill road to being able to pass people on it.

But I have no dyno to prove any of this. If anything the throttle response you get from MPFI is worth it.

dont mess with anything like the butterfly valve.. just dont touch that stuff. doesnt do anything but make it louder. and theres no way your car has 100 hp with a header and intake. sorry. mpfi swap does make a difference.. remember its a light car so 10hp will make a diff.

Daily driver, only hanging onto the car for 1.5 years, and only car...

Personally, I wouldn't even bother messing with it, but if you must, just as everyone else said -- mpfi swap (should be relatively cheap over there).

Ass$nyper

Holy crap this has some bad info in it.

You can do a mini-me. (vtec head, requires MPFI swap)
If not, you can put the Si (d16a6) cam into the d15b2 head. That makes more power.
Si transmission swap.

just pop a sohc zc in there and hmt. You will be set

I happen to have a '90 DX hatch with the B2 in it.

If I was only going to keep the car for another year and a half before moving very far away, I'd want to have as much fun with it as possible. Hell, I'd even look at it as gaining experience for my next project. It's all a perception thing and I don't know about you guys but I love working on my cars even when they're frustrating the expletive out of me. That said, let's move on.

You have a few options, all of which will cost $1k or less. You can put your own turbo kit togther and get close to B16 power without endangering your motor. You can swap an A6/ZC cam with a Y7/Y8 cam gear in. You can put a Z6 head on it. You can swap a Z6, D15B VTEC, SOHC ZC VTEC or non, or a DOHC ZC. There's one thing that every single one of these options will require, an MPFI swap.

One very important thing to keep in mind. Once you start modding your car, **** will start breaking...if you're driving it hard enough anyway. I'm now going to give you the absolute best piece of advice the guys who taught me how to build my motor and my car gave me. "Stop being a ***** with your car."
