I have d15z1 motor in my civic hb and I was wondering if I put a y5 intake manifold on it and a b16 throttle body and say a header if I would pick up any HP. Or if anyone knows any other things like those that could gain me some extra power.

it's a vtec-e. i wouldn't waste my time. that motor was strictly made for gas mileage. swap a B series.

Swap.

redjeep303

well im just looking for some extra power for a daily drive and would stuff like an intake manifold and throttle body help at all

redjeep303

im only looking to compete with a reglar v tec sohc

Then find you a regular vtec SOHC.
You'll still get great gas mileage, and it'll be alot easier to compete with one.
And their cheap. : D

SeanK325

The vtec-e isn't a race motor. Can't make power from anything.

Not gonna happen, you've got a ridiculously long geared transmission coupled with a 92hp engine. Intake, header, exhaust is basically worthless on a D-series. Either enjoy the awesome mileage only a VX can provide or swap in something else.

redjeep303

What if i did a z6 head

94EG8

You'll be in even worse shape then you are now. VXs had severely dished pistons, you will be making significantly less power than you are now.

redjeep303

ok but you guys dont think if i change the intake manifold and throttle body and a header that i wont get no extra power

redjeep303

i know it has like 96 but id be happy if i could get 115 or so

94EG8

You wont get anywhere near what you want out of it, you'll probably net under 5hp. For the cost of all the stuff you could probably pick up a used Z6, or even find an EX/Si transmission, hell even a DX would make a difference.

Your not going to get 20 hp out of that motor by upgrading it with your
listed parts. And whatever you may get isn't really going to be worth the
trouble and/or cost.


Maybe swap it out for something better, and make up some of the cost
by selling the Z1? There are people out there seeking out those engines.
It's an extreme fuel economy motor, and it was kind of ahead of it's time.

EDIT: I missed 94EG8's post before typing this

swap on a z6 head some arp head studs and a homemade turbo kit with a p28 ecu and enjoy

Shouldn't have bought a VX.

SeanK325

i wish i had a VX.

but it seems like redjeep303 is more concerned with power. if I were you, I'd sell the VX, or drop in a new motor. it's not just going to get you anywhere. no hate for you or the car. i love the VX, but your wants don't mesh with the VX's abilities.

94EG8

Z1 use some pretty spindly rods, if you're gonna spend that kinda money you might as well swap in a worthwhile engine first. Z6s are legitimately good engine for boost (especially if you build them) Z1's just flat out suck for anything but mileage. Also it's gonna be a dog unless it's in boost. Z6 head on a VX block with VX pistons is around 8:1 compression.

I've thought about doing an HX 5-speed swap into a '96+ hatch.
That would be kinda cool.

94EG8

I wonder if it would get better mileage than a stock VX, hatch shell would be a fair bit lighter than the HX coupe, especially if you used a manual rack, HX wheels, manual windows and locks etc.

redjeep303

i just had a 96 civic hx that i did a fully built z6 turbo swap and it put down 275whp but i sold it to get my supra so i got the vx as a daily driver for 400 bucks but i might throw an exhaust on it and a header just for looks lol

grumblemarc

lol. A header and exhaust. What a waste of money. So you'll be loud and slow.

94EG8

Word of advice. If you put a header on a VX it really screws with the leanburn and it will cut into your mileage.

redjeep303

What is leanburn if you dont mind me asking

redjeep303

well i figured anything that add performance cuts into mpg but i dont mind it
