Does anyone know how much of a power would be gained by supercharging the D16Y8? I know it makes 127hp stock and i would like to get about 225 - 250hp out of it, without breaking the bank if possible. And i was just wondering how close to the 250hp mark would a supercharger take me? And before all you turbo-fanatics put your two cents in about how turbos rule and superchargers suck, dont waste your time, i like supercharging better, and im looking for low end power. Besides, everyone and their mother has a turbo civic anyway, lol.

 

u would be lucky to get 250HP on a Bseries, and ur never going to get it on a D.

ive owned supercharded and turbo cars, and SC's do suck.

Ur going to waste ur money supercharging a D.

Ther is also a single-cam JRSC thread, but I haven't seen it in a while.


Personally I'd give it a shot with a modified M62 blower bolted to a plate where the AC normally goes and running through a FMIC, I've seen that done before. A M62 can flow enough air for 250 WHP, but it ain't necessarily easy to make it happen.

 

With a mock-up block/head, a welder, a grinder, and a 'square', you can make anything easily.

 

And I can't even weld I just bolt my stuff together and take it to a local shop to weld it.

.5" aluminum sheets sell for cheap on ebay, very easy to cut and make stuff with.

I take a gasket to a local hydro-cutting place, they scan it and import the image to their CAD SW so they can include it in the next match of .25" steel that they cut, depending on how many I need, this gets me custom flanges for $50-$75.

 

sovietxday made about 140 whp with his d series.
after that upset, he immediately started buying parts for his turbo project

 

If you read his post carefully you can see that he wants to take his 127HP SOHC motor and make 250HP. 250 "HP" is about 180ish "WHP", which is very possible on the SOHC, but it wont be cheap.

it should be over 200 whp to get 250 crank hp. 70 hp difference between your two numbers is slightly high- it would be more reasonable with higher hp numbers.

 

My old supercharged Z6 setup made about 160whp on a MD at 10psi. I made over 250whp with the blower and nitrous

 

Im not just pulling the 250hp number out of my @ss either, there is a method behind the madness (well sort of). My dad had a 01 buick regal that had a supercharged v6 that made 240hp at the crank. For an american piece of crap, this thing was fast as hell for a full size sedan.

Now that is on a car that weighs 3543lbs. giving it a power to weight ratio of 14.7lbs for every horsepower. My civic weighs 2262lbs. If it had 240hp, the power to weight ratio would be 9.4lbs for every horsepower, making this thing a hell of a lot faster than the regal. And just for comparison, a 350Z makes 287hp and weighs 3212. That equates to 11.2lbs for every horsepower. So a civic with 240hp would (in theory) beat a 350Z.

So 250hp is my goal. Ideally anywhere between 230hp and 250hp would probably be the most power than i could use in a civic realistically on a day to day basis. I read an article about a 580hp K20 stuffed in a civic and the joy that car is to drive on the street (sarcasm). So 230-250 seems like a more useable amount of power.

Does anyone know which companies make superchargers for the D16? I know Jackson Racing Does, but i dont know anyone else. I wish Vortech did, but i think they only make a sc for the B16.

 

Does your car have AC?

 

Which particular cars came with the D16Y8?

 

you are just not going to get anywhere close to 250hp with a stock Jackson racing supercharger system.

with a small turbo you can get a lowend powerband close to a JRSC setup.
like a TD04H-15g , GT25r.
recently did a custom 15g setup on a friends D16y8 with custom piping and a upgraded intercooler. and it was impresive at 7psi. a friend of ours who was considering a JRSC setup in his 94 EX quickly started reconsidering the turbo idea. he felt the low end was unbelievably good with the small turbo.

i think logging on a Hondata S300 we saw IAT's in the 110-150 degree range driving around on a 70 degree day
i know i've seen alot about how high the IAT's can get with a non-intercooled JRSC setup

i have a built D16y8 and i'm just about ready to throw it in my 88 civic with a GT28r turbo setup.

 

Cookie:

The 96-00 civic ex came with the d16y8, its the SOHC VTEC motor. I have also heard that this engine is in the 92-95 civic ex but i am not sure of this because i have have heard conflicting descriptions of the engine in the 92-95 civic described as the d16y8 and also as the d16z6, so im not sure what it has.


rmcdaniels:

Yes I have a/c.

Thanks for stepping up, Bro! Now, this engine is better than the d16z6? And how and why is that so? Aren't they both 125 horse at the crank?

 

both the d16y8 (96-00) civics and d16z6 (92-95 motor) both put out 127 at the crank.

jackson racing is the only company who makes a roots type blower for the d series- and in fact the only d series SC out there for sale. (endyn cough cough)

 

So no difference in the two engines. Why is it that I see people trying hard to get the d16z6's? Something about the heads?

Larry said that he made eight kits and they were such a nightmare it ended the fiasco right there never to resurface again. "Machine work only!", he said!

Hahaha, 146whp.

I had the same goals, and after a while just said **** it and went turbo... walla... 217whp on 8psi, shooting for 300whp on 18 and 400whp on 25.

 

If you want to keep your AC, then the only practical option I can think of is the M45 JRSC kit, which is pretty weak. Unless you can find one of the Endyn M62 kits, which look pretty decent, but they stopped making them. Of course you could do something custom with an M62, but it depends on how much fabrication you want to do. I'd love to see a ported M62 on a Endyn-style manifold with a couple of Laminova cores installed in it like the LHT manifolds have, but that's a lot of work and $.

 

SovXietday,
You got 217whp from 8psi on a D16? What brand turbo system did you use?

That right there don't go together.
Especially when talking about a supercharged setup, it would pretty much be a lot of custom work to get there for a D-series.
