There is some truth in that, but think abouit it...it takes what to make more HP, fuel thats right. A stock D will be about the best bet for high MPG.

Mine got good fuel economy because I spent the money on a really good tuner. I would've been closer to 30mpg if I drove with fuel economy in mind.

I regularly get 27 to 28 with my Accord (97 EX V6) and have gotten just under 30 when I really pay attention and drive like grandma (that is hard to do though). I've heard some say that they put it in neutral going down big hills but isn't that hard on the drive train when you put it back in gear?

I doubt you'll ruin your engine or tranny, but you can ruin your brakes. A lot more force is needed to stop the car with that much momentum. BRAKE FADE.

Leave the transmission in gear and push in the clutch. Don't take it out of gear. When you let the clutch back out, rev match.

As far as using the brakes to slow the car down. What costs more in terms of money and time to replace, brakes or a clutch?

Would that cause clutch wear, not worth the little higher mileage?

Blanco

The clutch wear I'm talking about comes from over-using engine braking. Use the brakes to slow the car down.

Also, you'll cause damage to the drive-train if you just put the car back into gear from neutral without rev matching. To learn about rev matching, go to: http://www.turnfast.org Even better than pushing in the clutch, is just putting the transmission into the correct gear and then lifting off of the throttle to about 5%...just barely pushing the pedal down. BMWs have a nifty little MPG gauge under the speedometer and when I do this is registers 30-45mpg depending on conditions. And that's with a 2.5l six cylinder on flat ground.

Hey, what do you guys think of a D15Z1 as a replacement? IDK the year but do got the tranny for it too.

AHHVTEC

for good gas ya, performance not so much

Flippinjig

Would it make much difference to use the Z6 top end? What are the differences in the tranny's?

AHHVTEC

yeah you can put the z6 head on there it will help, and im not sure on the tranny im perty sure there longer geared than the ex or si

Flippinjig

Will Z6 ECU work with 15Z1?

efhondakid

Youll have to get the P28 chipped with the Z1s basemap.

Ok, now I'm really going to show my ignorance. D15Z1 lower half, would you stick with the Z1 head and tranny or use the head and intakes and tranny from the blown 16Z6? I did get a P07 ECU with the Z1 motor too.

efhondakid

Performance or gas mileage oriented?

I want good mileage but if the performance would be significantly better and mileage suffer not so much then.........

Flippinjig

I've got another Z6 motor too. Am I in the ballpark to say that I could get mid to high 40's mileage with the Z1? Can I get low 40's with the Z6 but still have alot more power when I need it?

AHHVTEC

i say 30s with the z6

The only reason why a d15z1 gets great gas mpg, is because the intake ports are tiny, doesnt require so much fuel and air, as well as the pistons are low compression. other than that your stroke and deck heights are the same as every other 1.5 block. Im only using a z1 block for a build because its a good block, No signs of over heating, when i got it, green coolant, block surface looked brand new, new water pumps and oil pump. and i only paid 100. Even though i didnt realize till later. i didnt want the head. I'm switching the pistons from a d15b and the P08-1 head. I'm basically doing the same build as blanco. but not as clean as his is. Even though after seeing his now. I want to take that extra effort to make it look even better. yes.. im jealous of you blanco.

If i were you. Just pop the Z6 in. Unless you want to build the z6. then go ahead and put the z1 in. save gas and money, build a stroker from the z6. Im not sure if i got my numbers right. but you could find a d17 block and use the crank shaft (the main bearings are the same size) and then use 1.5 rods on the 1.7 crank and you have a stroker. of course I dont have my numbers right. I havent taken the time to check to see if that adds up right. but Either way. it'll be cheaper than a full stroker kit.
