Okay, I'm the proud owner of a 89 DX with only 60k miles, but there is one problem with this car. Its TOO slow. Yes, it is only my daily driver.. but with the AC on, it goes like a snail... and good luck passing on the highway - too dangerous. So, I've been doing some thinking..

If I go Mini-me, I probably won't gain much power, and it will be a pain in the ***. ECU swap, MPFI conversion, Swapping head... I'd be taking apart a perfectly good engine and I don't really want to do that for a torqueless SOHC VTEC head.

Now, I ran across this. http://www.homemadeturbo.com/turbo_projects/d15b2/
a DPFI Home made turbo. Looks easy, cheap, and I think i'll probably make more power than I would with a Mini-me.

Edit: If I boost i'll be doing MPFI, but will be keeping the head and everything else.

Vote based on cost, power gains, and relibility.

How would my low mileage D15 handle a small RHB5 turbo? This turbo is stock @7psi, but could I turn it down to 5psi if I plan on throwing it on my engine?

Do it, woo! I think i'd be worth swapping the MPFI Mani and Si ECU in there, though. The difference amount you get out of a DPFI Turbo setup and a MPFI Turbo Setup on the same engine is absurd. It's worth the little extra work and $$

If you have all the turbo parts lying around, though, hook it up! Should be a lot better than stock B2.

 

i've heard about that DPI turbo and almost did it to my b1 i just dont feel it would be reliable.

MPFI or mini me then boosting or swaping will be alot easier and safer.

 

boost that beauty yo!!!

 

Where's the option for both :D

 

I'm gonna have to say turbo as well; at around 5 psi, that would make your car good enough to pass people, get onto on-ramps, etc safely.

I'd rather not pull the head.

How reliable with 5psi be on my stock D15.. Keep in mind it only has 60k on it.. and I want it to last a long time.

Thats what I did...but IMHO Turbo &gt; Mini-Me

Mini-me felt good, but the power that the turbo added blew me away

I think that if you get some engine management (like Z-Dyne's OBD-0) and get everything tuned, not for crazy performance but for good city driving and longetivity, I think that you would have a reliable turbo car on your hands.

 

If you got the money go with the turbo!!!

It'll only cost a few hundred bucks... I'd be using a probe turbo.

Sounds good.. but is that ECU necessary for relibility? ECU Might be a problem also, car is auto. What if I were to tune 5lbs with an FPR/Wideband o2..

 

Do both dude, screw it ur already going mpfi might as well pull the head and go v-tec too.

 

mpfi conversion with a vtec head and the little turbo on 5psi for a little more hp plus a little more fun

 

Is it just me, or does anybody else see the irony in turbocharging a car so you can pass people on the highway?

 

Get the D-series turbo...that way if you do end up blowing the engine you can up grade to a larger D-series and still use your turbo kit. D-series are pretty cheep, that's why I would do it.

 

i wouldnt waiste your money on a dx AUTOMATIC.

if you want to pass people on the highway then convert to manual!

i wouldnt turbo a automatic honda,
