I know nothing on this engine or anything about it. But someone I know is looking to supercharge a sohc non vtec engine. He says its a pqyd8. Is this engine worth doing any mods to and is it possible to get any power out of it? Also is this engine better suited for a supercharger then a turbo charger? Keep the flames to a minimum as well please! hah, I did search and came across alot of info on other engines but nothing on this one specifically.
I may be back with more questions for myself as I am planning on piecing togeather a turbo for my B18b.
Thanks!

 

bump

 

Um what motor is it again never heard of that one you stated. You sure thats right? what car is it in?

 

Im not sure if thats correct. All I know that it is a stock SOHC non-vtec

u sure it's not a d16y7?

 

a supercharger on any SOHC honda motor is very boring.

turbo is the only way to get power out of the SOHC in my opinion

platinum.

I just watched dyno of a 1.5 non-vtec running a T25@9PSI and it was making 155lbs of torque at 5000RPM. Not too boring, but like he said turbos aren't boring.

 

Yes d16y7 is correct, he gave me the wrong code.

 

the rods in the non vtec sohc engines r very week and the pistons are prone to cracking under boost but he could use an sohc vtec bottom end and be ok,my first supercharged engine was a d16z6 sohc vtec with crower rods and srp pistons i was making 172whp and spanked my buddys turbo LS in a del sol

 

Supercharger is a bit easier to work with and maintain. It's safer in that there will be no boost spike, and they're just overall a lot easier to work with and work on. Turbo's are complex and if he doesn't know what he's doing... well... he's in trouble.

On the other hand, turbo also has the potential for putting out a lot more power. So it's whatever he wants to do, or feels safe in doing.

Personally, I'm starting on a project to squeeze 200whp out of a JRSC setup on my D16Y8 (sohc vtec).

All SOHC shortblocks are the same, only the head is different on VTEC vs non VTEC. this is true at least on y7/y8 engines.

No. Turbos aren't complex or any harder.

i somewhat agree.. .. a JRSC on the Y7 will net you about 130whp.. to me what a waste .. unless you get one for like $500 .. ive seen them on ebay for around $800 but not often ..but on the other hand a turbo will put you at least around 175whp.. tell your buddy to get online and do some searching/reading .. he can learn so much about each way of boost

What is there to an SC? You buy it from JR or used and you get most of what you need, everything totally assembled. Just plug and play and you're pretty much good to go at 6psi.

There's a lot of fabrication that goes into building a turbo setup. Custom downpipes, charge piping, intercooler fitment, turbo fitment, etc. Then after that you have to worry about boost spike, leaks, and oil lines.

Once it's on and together, sure, they're the same when it comes to tuning. I didn't say one is more reliable than the other, I just said that one is easier to work on than the other.

Speaking of which, I got my SC for $550 I would have gone turbo otherwise.

 

Well maybe they are harder for somebody like you, but for us normal people it's not hard.

 

My JRSC D16A6 with D16Y7 head made 175 whp and 145 ft/lbs of torque at the wheels. I was getting 13-14 psi at about 6,500 rpm, and then it would spike to 17 psi by 8,000. The problem was the OEM cam in the Y7 head. The cam just would not let the boost into the motor. I had everything else opened up (Kamikaze header, 2 1/2" exhaust, 3" short ram intake, 60mm TB, ported blower, S tube and manifold). I made 135 ft/lbs by 3,000 rpm, and it peaked at about 5,500 rpm (145 ft/lbs), and still had 135 at 7,500, so I know if I had changed the cam, it would have made alot more power in the top end.

I didn't want to make alot more power, as the longblock was OEM, and with the loss to the blower and the 15% loss in the drivetrain, I suspect the motor was actually producing somewhere near 235-240 at the crank (remember, blower is after the crank).

You could easily make 200 whp with a good blower re-work and some decent engine building (good cam, stronger rods/pistons, good tuning).
