I was just wondering if anyone has ever turboed the D16Y5 motor. Just wanted to see if it has been done.

 

it's been done. check out turbod16.com

if you're gonna do it, i'd get a chipped/socketed P28 ECU and a ECU conversion harness from phearable.net.
then after you install everything, go get a tune!

Hey trust u must like my threads. What will a P28 ecu do for me and how is it different than my d16y5 ecu??

 

P28 is the OBD1 VTEC ECU that you would have to get chipped and tuned in order to turbo a D16Y5.

 

Will the p28 ECU run my y5 isnt that ecu for a z6? The sensors (obd2) and vtec is all different for the y5 compaired to all other vtec motors. Wouldnt it be simpilar to use a V-AFC with the stock ecu? Also the y5's vtec kicks in at 3000rpm and I think the z6 kicks in around 5000, I would rather keep the lower rpm engagment. Keep in mind this is all just me being courious, I will be swaping a y8 most likely or at least the y8's head. I just wanted to see if it is possible to boost the y5 as I have been told you cant cause the y5 needs the high back pressure from the stock cat.

 

lol... i know what a d16y5 is and how it's different

VAFC's suck... get a real tune... don't use a piggy back

it's for a Z6, yes. It doesn't matter about the sensors.

The P28 will run the d16y5, and not safely at all if it's turbo'd. If you read, you would see that I said "chipped and tuned."

You would get the tuner to adjust VTEC to the optimal point (do 2 dyno runs, one with VTEC engagement all the way down so , one all the way up so it never hits VTEC, and then compare the two charts and then set VTEC engagement to where the two different graphs' torque (or maybe it's HP, i'm not sure) curves would cross each other.
And then of course, the tuner would also adjust your fuel and timing maps as needed.

And who told you this BS about back pressure?

I know that the p28 y5 hybrid will need a tuning after turboing was wondering about before turboing. Will this basically make the y5 a lower compresion z6?? If so cool no need to do the y8 swap. As for the back pressure a local shop told me the y5 is tuned for running with high back pressure and will loose power without it. I was told that when I wanted to put a header for a y8 on it. And I still dont see how the vtec will work properly with the p28 ecu, will the p28 change it from vtec-e to vtec? Thanks trust forthe info, u seem to know alot about this.

 

No. Compression has to do with the pistons, stroke, cylinder bore, and deck height.
Don't put the P28 in before turbo. I'm telling you to get a P28 because that is the ECU you will need to get tuned for turbo application.

The ECU adjusts itself. With minor mods like intake, header, and exhaust, the ECU can fix itself to work optimally with those new parts. Even if it is tuned for small exhaust piping and restrictive exhaust flow, the ECU will notice the better flow and will adjust itself accordingly.

All the ECU does that's VTEC related is control VTEC engagement point, air/fuel ratio, and timing. The P28 will make it regular VTEC (mostly), but your tuner will fix it to run right.

 

Ok cool thanks thanks for breaking it down for me. Do you know anyone in Arizona that can do the tuning needed for this set up. I think this will be the way I will be going? What about emissions, will the obd2 to obd1 pass? This will be my daily driver and needs to be streetable.
