well i also have an 89 hatch Dx and its smokes the crap out of my 93 CX hatch i just bought.. so far my 93 has accel plug wires. ractive exhaust and ractive intake.. but it is still slow ...its a 5 spd ... my 89 hatch just eats it alive so is there anything else i can do to upgrade the puny 92stock HP ?? help me please.

its a 1.5L D15B8 i think

well the first step to making it faster would be to realize the cx has 70hp stock not 92

try getting a intake header and an exhaust then adjust the timing and throttle cable

DX187VTEC

first dump the reactive stuff.....second swap it

Engine swap!

I'll have a D16z6 available after I do my engine swap in a couple weeks. It's in my 92 Si right now. You aren't going to smoke any 5.0's with it, but it is a fun engine with its 125hp.

ok well how many valves does this motor have ? 8 or 16? also . i c u have a 98 DX motor 4 sale .. will it bolt into my Cx?

mike
its the d15b8

-Whitey-

8 valve

DX187VTEC

i have a 98 Dx motor sittin in storage i yanked it out.....its a beast yo 70,000 miles all stock ran a 16.7 only time i ran it at CMI....... 106 hp stock

I had one of those. It's 1.5L; don't expect a lot. It's made for economy, not speed. I got almost 50 MPG on a drive from North Carolina to Chicago.

Personally, I wouldn't put any money into go-fast parts for that engine. If you want speed, save for a swap. Any swap.

civicracer1993

can u email me with some specs on that DX engine and prices and stuff. does it include alll parts and will it bolt right in? my email is civicracer89@yahoo.com

thanks
mike
why in the heck did honda make an 8 valve ? its a waste,.,,

SH0ck-D

SWAP IT!!! B20 into that thing would take OFF! 14s! baby!

cxSOHChatch

gotta agree its fun!

dont bother with the 1.5 man...save up and go for a swap and I/H/E! How fast do you wanna but? and wot will the usage of your car be?

fred92htch

For fuel economy. I just bought a '92 CX for my wife. She gets 44 mpg CITY driving. It's a perfect car for her running around all day.
The only way to get power out of your car is a swap. I also have a DX with a GSR swap for me to fix up and have fun with but we are leaving hers alone.

Don't waste your time with a CX motor. That bitch has 70hp...there isn't anything you can do to make it fast. Even if you bought a turbo kit for that motor (which i DO NOT Suggest at all!!) it would still be just as fast as a DX hatchback...maybe close to a stock SI hatch. Just save for a swap...B18B, B16A, B20B(or B20Z ), B18C(1 or 5), basically anything...70hp isnt getting you anywhere and never will. You will probably blow that motor before you can even put 70hp to the wheels

Dont waste your time trying to make the stock cx motor fast. Ive ridden in a '93 cx w/ ex tranny, ex intake manifold, and dx exhaust manifold, and it would still have gotten killed by a normal dx hatch.

Either swap the motor or, if your on a serious budget, throw on a vtec head and ex/si tranny.

ransack

16.7 damn that is beastly.

I bought a CX for my wife and had the same reaction.... too slow.

Not wanting to do any serious mods, I put a DX 16 valve head on it (I used the CX intake) and it does have more power. We're not talking alot, but at least now I feel safe pulling out into traffic. This winter I'm definately putting a DX/Si tranny into it though. Those long gears don't do much for acceleration.

AND yes, the CX 8 valve motor does have valve reliefs for 16 valves, I have pictures to prove it.......

Cynical 1

Yeah. I'd swap the 16-valve DX head on it, get a header, exhaust, intake. That's about all you can really do for cheap.

Stock CX is 8-valve and 70hp. DX is 16-valve and 108hp ( I think )

I solved the problem of my 93 CX being slow by swapping a B18C1 into it. Slow no more.

I'd start saving for a swap, and just enjoy the 40+ mpg you'll get from the CX, or just drive the DX.

oldskool_rex

don't listen to all the doubters here....I decided (and partially my budget decided for me) that rather than swap out my CX motor, I would play with it. D-series parts are cheap, and you can make it a fun car without removing the motor.


2 things kill the CX, the head, and the trans. Get an ex/Si tranny (they are all the same from 92-00), a decent clutch, adn do a VTEC head swap. I did this stuff and the car is a whole different animal. Even though it is 1.5L, the compression is about 10.3:1, and that is plenty to move the car buch better.

I plan to turbo my mini-me, which is not necessarily cheap, but I will be putting easily 200 hp to the wheels, and way more torque than a B18. That WILL smoke 5.0s.

Get a big old fat shot of nitrous in there. Zoom!!

And when the motor blows, you'll have an excuse for a swap.

well, a '93 CX still has around 100lb/ft of torque!
But the tranny has horrible gearing and the head is engineered for fuel efficiency not horsepower.

1) buy a 16 valve Si head cheap, then mate that to your CX bottom end
2) buy an Si tranny
3) get an SRR final drive from AJR
4) install a lightweight flywheel

-and you will be ready to rock.

swap a b16b then a I/H/E then get some full coilovers then paint it then get wheels then new interior then paint it again then get new wheels and sell it

oldskool_rex

you know, CX flys are already lighter than other d-series flys...they have less material on the backside.....

owen_the_soyboy

but, um, no way as light as an aftermarket light fly....
