Good evening everyone,

I am fairly new to the EK/D16 community so I thought I would get some input from the experts! I am on my way to saving up for an EK Hatch with a D16Y7, and after much simping, I have come to the conclusion that I wanna make it fast/trackable. I know the D series motors take a lot to work to make power but I have a base goal of 250ish(+ or 0 10hp)whp. I was wondering what ya'll know about making that possible. I have read that the sleeves in these cars can take 300-400 safely, but I wanted to know what parts(specific or not) I would require or some healthy recommendations. This will most likely be my daily, but I just want to reliably push 250whp N/A. If that seems far fetched it would be greatly appreciated on why it isn't possible, why it is possible, etc.

Thank you,
Auggie

250whp? N/A? Daily? Fast/trackable?

Error... no compute...

Need to read some more on here for sure, and you'll need to be turbo. No if ands or buts about it.

What kind of track? Drag, road course, etc?

To be honest, I don't think that number has ever been done in an NA D before honestly, maybe 230 or 240, I don't think I've heard of the 250whp # being touched before (I could definitely be wrong, but if it has its a fucking unicorn), but those engines are the absolute furthest things from a daily, have basically unlimited budgets, practically want to destroy themselves, and only run on nitromethane.

The D architecture just isnt designed to support that power, the engine itself is the limitation. People that do run 200+whp in a D are approaching 2.0L if not at 2.0L or more, meaning it needs to be significantly oversquared, and it needs to rev to the damn moon, touching or exceeding 10k rpm.

To do that, I dont think you quite understand how much work that really is, or the cost, and why it isnt practical for what you're trying to do.

Think of it this way, when B series engines have a HARD time touching that number with just straight bolt ons, a rebore for moderately wider pistons, and a tune, and their architectures are much better designed to support power above 200whp, you'll see why our D's are terrible choices for those numbers in NA trim, especially for a daily!!

Turbo is the answer for the numbers you seek.

he did say
and after much simping,

Auggie just needs to study a little more.

Mines always trying to blow itself up at maybe 140 ish whp 🤣 though it was solid until about 120k miles, it's nearing 180k now and is showing it. To be fair, it's driven hard for 3 or more hours a day and climbs a car killing hill twice a day through most of summer.

Daily, trackable, with even 200+ whp N/A is pretty unlikely.

There are a couple things you can knock out to grab a few more horsies. Mini Me (or a new engine if your inclined), port, rods, pistons, cams. There are plenty of builds on this forums with dynos posted for you to get an idea of what's probable.

Might not be a bad idea to temper your expectations a bit and go for a more moderate build. You don't need a whole lot of power for a track build.

That being said, don't let me stop you cause here's an example of a D16z6 making 191 whp on the dyno:

Yeah, I had a feeling that the D16Y7 wouldn't be capable of a number like that, I just wanted to throw the idea out there to see what the crowd thought. I really just want a car with a good power-to-weight ratio. I'll go ahead and do more research to see what extent I can do.
