why is my d16z6 turbo slow?
i have a 94 civic with a d16z6 engine turbo. I have the greddy 15g turbo running 6 psi and it doesn't seem to be all that much faster. I raced a gsr civic with an eldelbroc intake manifold, intake, header, exhaust, and stage 2 clutch and he beat me by 2 cars staring from 40 and going to 100 mph. All i have done to my car for performance is the turbo and blue box, <U>without</U> bigger injectors and a axleback muffler . what do i need to do to my car to make it faster. Oh yeah and my clutch slips like hell when i change gears. Also the turbo seems like it doesn't make as much power after 5500 rpms.

faster = search, read, and learn...
bigger injectors, fuel pump, different fuel management would be lovely, and it looks like your the one that needs the stage 2 clutch...
again, research and learn buddy....

I've never heard of someone feeling like their car isnt much faster after slapping a turbo kit on...interesting. As mentioned above i'd say get a new clutch...then maybe bigger injectors and a fuel pump

Sounds like a boost leak to me. I run that kit on the stock injectors (with a diff fuel pump and E-Manage) and it pulls like a crazy. It felt 1000 times different than a stock hatch I drove a couple weeks ago.
hehehe..

definantely get a new clutch and get better fuel managment with a 2.5-3" catback exhaust. Also I would expect that gsr civic to pull on you anyways if you are only running 6psi.

Re: (91civicDXdude)
if your clutch is slipping, all that power has no where to go .
turning up the boost will make it slip more, more power will make it slip more, you need to start with a clutch. and thats about it. start there.

I agree, doesnt matter how much power you have, if it cant get to the wheels its pointless...... new clutch

After I put my greddy kit on I was only running about 2 psi of boost. turns out i had a horrible connection on the intake side of the charge piping. I fixed that and started running 4 or 5 psi and noticed a huge difference over stock. Make sure that you are reading 6 psi. the difference should be night and day from stock.
Are you running an intercooler. I ran mine for about 2 months unintercooled and I just put one on this weekend. Again a big difference from before the car pulls harder and the turbo spools much much quicker.
Cliff notes. Check all piping connections and make sure that your exhaust manifold is flush against the block and you are not leaking boost anywhere. if you don't have an intercooler get one. Any you should feel much quicker than stock.

you need to start there. with a clutch. proper tuning and higher boost levels will come into play when your clutch can actually handle the ammount of power your engine is putting down.

Yeah, that's one upgrade that should be high on your list. He has a very good point. As previously mentioned, you might want to check your piping/hoses for any boost leaks as well. Other than that, there are a couple of upgrades you can do...upgrade your fuel system/delivery, front mount intercooler, upgrade to a bigger exhaust/3 inch...etc...
Other than that, your friend basically caught you "slippin", not talking bout the clutch, either
Good luck, and hopefully you'll be able to get your "revenge" on you buddy soon

I am running a B17 in my 93 CX hatch and have raced two boosted single slammers and walked them both hard. Like the guy above me said, a properly running swapped hatch should take out a boosted single slammer, even if the single slammers clutch is holding.

Re: why is my d16z6 turbo slow? (Hybrid93Eg)
Yeah...now that I think about it...GSR EG's are low 14's high 13 second cars...at 6 psi if you are running under 15 seconds in the quarter mile i'd consider that an accomplishment

I cut 14.3 @ 98mph on my current setup in my hatch. That was with shitty traction, so I am sure I can do better... When I had my 93 EX, the best time I ran with a supercharger was 15.1... That was with the blower and all the bolt ons including a tuned cam gear. I wouldn't think the Greddy kit on the same car would be all that much quicker.
