#201206 do you mean the D15z1 engine (vtec-e)?
That engine is designed for one thing only = fuel economy.
It does have the longest geared manual transmission of the D series motors, so swapping it out for a short geared D16z6 manual tranny will help a lot in acceleration. :thumb:

The d15z1 was never meant to be a fast motor. Sticking to traditional 1/4 mi. tricks will help though. Lighter wheels, remove spare & jack, rear seats etc... to reduce weight.

You could do intake/header/exhaust but it's probably not worth the money when you could keep saving for nitrous or even turbo.

#201419 I checked and its a D16A6 Also known as D16Z2 its not the D15z1

so would that change anything if its a D15A6?

so besides the headers muff and filters is there other tricks like the tranny

you could share to make it faster without using turbo and nitro

#201424 there is no D15A6....




maybe that was a typo and you meant D16A6? that would mean it's been swapped to a old CRX/EF Si motor which definitely takes better to bolt ons.. :thumb:

#201528 Yes the D16a6 is a good motor. Although it is non-vtec, it has a huge selection of aftermarket parts available. :thumb:

N/A builds on these motors can get pricey, you'll make more power with a turbo or nitrous.

How fast do you want to go and how much do you want to spend?

Is this car your daily driver or track toy?

#201672 its a daily drive but sometimes i go for spin with it

with the headers what type of headers and mesurments

and with the filters is it okay without the tubing i will directly connect the

filter to the fuel injection is that good or not?

just find a header that is made for a d16. If you put your filter behind the engine its going to get warm air from the engine instead of nice cool air. The further forward on the car the better.
