My turbo project

Here is my WIP turbo project. So far not tuned or properly driven.
D14Z2 engine with stock bottom end
D16Z6 intake manifold
ARP headstuds
Aliexpress turbo manifold
T04E journal bearing turbo.
PSR 38mm wastegate
DIY 2.5" downpipe and screamer pipe
ECU is a Speeduino UA4C SeaFox, but still setting that up. Stuck on getting ignition to work properly right now.
Since the bottom end is stock, I'm aiming for 7psi boost and running the stock fuel pump. I will use D16Z6 240cc injectors.

It's not a mini-me, just a D16Z6 valve cover. But I plan on swapping over springs, cam and rocker assembly from the D16Z6 with locked vtec.

Work in progress breather setup

Excuse my amateur welding. This is my work in progress crank case ventilation setup for my turbo civic. I'm attaching two 10-an fittings near the stock PCV valve of the original D-series oil separator box. There are several reasons why I think this is better than using the off the shelf 10an block adapter.

  • The inlet of this box has an I.D of 22mm, 380mm2 while a single 10an is only 160mm2. Two 10-an makes much better use of the available flow.
  • Oil separator before the crank case gases reach the catch can.
  • Keeps stock PCV valve, and with the An fittings capped off it works just like stock. This is useful because I want my car to be able to pass MOT inspection in europe, and I want a quick way to turn the car N/A and remove catch cans if needed.

No one seems to be doing it

Joke aside I'm also doing it.

External MAP sensor input on Sea Fox UA4C vB3b?

Currently in the process of setting up my Speeduino, but I am running into the issue of having to use the MPXH6400A onboard map sensor. My main two issues with this sensor is.

  1. It's tiny, has no barb on the nipple and I can't get a hose stay on it worth a damn.
  2. I have also heard of people having problems with these sensors, and just having a more robust built sensor that is also interchangeable just seems better honestly.

I have wired my OEM MAP sensor signal into Spare Input 1 of the Speeduino header, but in TunerStudio I am unable to assign an arduino channel for an external map sensor and am effectively forced to use that onboard sensor whether I like it not.

Can I somehow modify my board to use an external map sensor instead, and what considerations do I need to take? Can i simply say bend the MAP signal pin on the board out of the way, and solder a new wire directly to the Arduino?

I was planning on using an OEM Denso Honda Civic map sensor if that helps.

D17 gearbox

TLDR: I'm looking to put a D17/D16V1 7th gen EU8 gearbox into an EK but can't find any previous examples.

Bare with me, I'm european and our engines got some different names than in US.
My project car is basically an EK with a D14Z2 (which is basically a D16Y7 with a 1.4 bottom end). It has some form of S40 gearbox, and I see time and time again people recommending the S20 gearbox. I have an S20 gearbox but it's in really poor condition.

I also have an EU8 which comes with a D16V1 (basically a D17 but 1.6) with coil on plug, EGR stuff, cable shifter and what not. The thing is the EU8 gearbox has very very awesome gear ratios and I love driving my daily. I wanna have these gears in my project but I can't find any example of anyone having ran this gearbox on an EK with whatever D-series.

The idea would be a cable shifter box similar to what you run with a K-swap and a custom made engine mount. Starter is moved to a different location as well, but should clear the distributor nicely. The bell housing bolt pattern and rear engine mount looks the same visually.

Have anyone tried this before, or have any ideas of other stuff to check before just sending it and trying?
