New to Turbo set-ups
2000 Civic EX Coupe 1.6l Auto with (Turbo)

Can I swap in a manual tranny onto my d16y8 VTEC turbo automatic? I’ve been reading turbo’s play he** on the auto’s and it seems to be the case.
Bought this car about a month ago. Needs some work: oil pressure hits between 80-90psi on cold start-up. Settles around 20-30psi after warmed up.

Oil pressure goes up during acceleration and sky rockets when turbo engages. Also notice I cannot floor the car as it causes the car to bog down pretty bad right in the middle of boost and acceleration. If I use about half pedal and the turbo engages it pulls pretty hard and will do it’s thing without any real issues except: I’ve noticed sometimes after slowing down to a stop and trying to go again it’s like there’s no power to the engine. A quick shift into neutral and turning off, then restarting the engine, the car is fine again. Like it never happened. Obviously, doing that resets something?

Also, can I swap on a DOHC VTEC Head? What would I need to complete the swap if it’s possible...ecu, harness, whatever extra?

Or...what can be swapped into this car engine and tranny wise? I do not want an automatic, love the ease of not shifting but sick of limitations for performance parts availability and upgrade possibilities.

What should my oil psi readings be on average during boost? Why might the car not be finishing it’s cycle during boost if floored? Too rich maybe, injectors too big? Needs a dyno tune?
I do smell gas in my oil and just changed it about a week ago with full synthetic and K&N filter. Also noticed a small oil leak which I’ll track down ASAP. Think the leak might be due to such high oil pressure, but will see once I locate it.

I thank any and all who reply in advance...here’s a few photos day of purchase at previous owners residence.

 

I wouldn't make any radical changes, but first optimize what you have. Run a scanner to see what the air/fuel looks like, check everywhere for leaks, keep boost low until everything seems ok. Then, depending on what you want to do, you might need a tuner tool or take it to someone to tune the current config on a dyno for you.

 

Straight from the fast and furious days!

You can manual swap the car, but it's more than just the transmission. You have to also consider getting the clutch, flywheel, slave/master cylinders, bearings (should come with clutch kit), clutch lines, pedal assembly, and maybe ECU. I'm not sure about the wiring aspect. There are plenty of DIYs and write ups about this though. Here is a thread, first result on google. https://honda-tech.com/forums/honda-...4pics-1337459/ I think install is fairly straight forward, but might be tough if you're not familiar with wrenching on cars.

You cannot put a DOHC head on your SOHC motor, it simply won't bolt together and will not work.

My oil pressure is ~75 cold start, 20-25 warm idle. and goes up about 10-15psi per 1000rpms. Highway cruising speed has me at 50-60psi. I think your oil pressure seems fine. If you don't have your block/head vented, you could be experiencing issues with crank case pressure which would be pushing oil past your seals.

If I were you I'd just focus on a catch can setup and swapping that 5 speed. Of course also make sure it's maintained.

Non turbo/motor things I'd work on (and I don't want to sound harsh, but the style of this civic has aged...poorly in my opinion) but if you like it then run it. I'd probably get new bumpers, lose the skirts, and get a different wheel/tire setup.

Lastly, the turbo set up you're using is pretty dated in today's world. You can make more reliable power with proper ECU/tuning/injectors, intercooler, etc.

Good luck!

 

^^^ This..

In the style being "dated". Don't sweat that. Looks clean as **** from here. Under the hood, I would convert to manual and then add an OBD2>1 Adapter harness and drop in a P28 with Neptune, S300, something a bit better to tune with. Chances are that is a stock block and the current setup is doing you no better than 200 to the wheels at best. Keep it or update it a bit with the addition of an intercooler and piping and 2.5" exhaust from nose to tail. Clean car with potential!!
