i have a 93 civic w/ the d16z6. It's built w/ wisco 9:1 pistons,eagle rods and a race eng. block guard. the head is stock. i'm running the greddy 15g kit at 12psi. I know i can't really boost any more on this turbo. But could i add a 55 shot dry nitros(Zex) if i get bigger injectors etc., and a hondata? I just want to know if the block could handle it. Thanks alot.

You can take it up to 15psi.. Thats about 30 more horsepwer. Why muck around, just get a bigger turbo and boost heaps probably cost as much as the NOS kit but you don't have to keep refilling it.

td04civic

well i can't really upgrade the greddy kit. so i want to make up the power with nitros. i just wanted to know if the block could handle the power. thanks for the reply

Hey man do some checking I'm quite sure some other turbo will bolt up, if not just get another manifold.. I think the block will take it as long as you have decent tuning.. Or do you want to say I have turbo and Nos yay........ I would just up the boost to 15psi to begin with. Then check to see whether you can run a bigger turbo off of that manifold. Ps I would not run that kind of boost level every day. Just when racing or for laughs.

td04civic

yeah i checked and there is no other turbo that will bolt up to the Greddy manifold. I guess i'll just boost it to 12psi and run a 55 shot to make up for the lost boost. Anyone else has any input let me know. thanks

Your biggest problem is going to be the stock block. Although the block gaurd is going to help, you still start to warp and could break things when you get over 20-22psi boost. The greddy kit will boost up to 15psi if you really push it..make sure you have a big intercooler as its gonna be pushing alot of hot air at that boost level.

I had a friend that dyno'd 300hp @ 15psi on a fully built d16z6 on a little greddy kit. I believe that crank HP..so maybe 250whp.

I dont recommend a dry shot (ie zex) kit with a turbo as the fuel pressure is going to get upward pretty high. You also might want to look at the AEM EMS as it can control fuel under NOS. (very cool)

Ive personally boosted up to 18psi on my old build block, JE 9:1, crower rods, block gaurd, stock head, very similar to your setup, with a t3/t04e turbo, and it handled it just fine just hauled butt.

If i were you i would either port the hell out of the turbo for more flow and port the wastegate and put in a bigger flapper...that should help. Or upgrade your manifold and turbo to a larger model, maybe t3/t4, Big 16g or 18g, maybe a Big T28. Im not sure if a greddy 18g can bolt up to your d-series manifold but that could be another option.

But to answer your question..if you get the fuel right, your block should hold 12psi and a 55 shot. It will be one hell of a ride though. I wouldnt try to push more boost / nos through it then that though. If you wanna go more i highly recommend you sleeve the block.

D series engines can handle 12psi stock so if you have a built block then I would recommend a Nitrous Express kit. Don't fool around with any other crappy nitrous setups. NX is the best on the market. Check out arfabrication.com His racecar is sponsored by NX. He'll give you a good deal on the kit.... and he'll be able to advise you on how much of a shot you can handle...... maybe a 75 shot.......

Im currently runing 8-10psi with a t3/t4 homemade kit with 35shot dry n2o on a stock LS block with 550cc injectors and hondata s200. No problems and I have juiced about 15 times already with this setup. This is a temperary setup while i build my b20z.
With low shots of n20 its better to run a dry shot, like 25-65shot.

That Greddy kit uses a Mitsubishi turbo....Im real good friends with Sean down at Extreme Motorsports, im sure he could set you up with a badass Mitsubishi flanged turbo....We have one at the shop that has made 460whp on an Eclipse...It uses a TO4E compressor housing...And I would never recommend dry nitrous. You can run a wet system down to 35hp if needed...And yes turning the boost up 3psi may give him 30hp BUT it will never give you the torque Nitrous gives you. That 35shot of wet nitrous will probably jump your torque up 50-60 ft #'s....Which all Hondas lack....

where can i buy this fictional motor of yours?

lets not even mention the rod stroke ratio of the d16z6.. imagine how fast his rpm must climb if he ever got that setup. i imagine a few missed shifts.

Im running a standard t3 flanged turbo on the greddy manifold. The manifold has an adapter plate welded to it and has worked fine for quite a while now.

Ive been running 10-12psi on a stock block for the last year, and 15psi on race gas also on a stock block. They handle it just fine. Tuning is key my friend.

Thanks everyone for all the responds. You more than answered my question.

sporkcrx

what management are you running?? thanks, sean

I run the AFC hack...my normal everyday boost setting is 11-12psi anymore i get a CEL. Running 15psi i run a erl mf2 with two 550cc secondary injectors...as the afc hack cant help me there.

sporkcrx

what's an erl mf2??? extra injecttors? also, what do you do for timing, just retard the dist. a couple degrees and call it good? reason is, I might be peaking at 10psi on my stock d16a6 soon, and will be using the SMC with 450's.

you can also upgrade your turbo.

i emailed them and they said this upgrades your turbo to an 18T. although i'm not sure about the spool times and how much more power this will add. anyone?

SleepersOwn

are you the one with the white civic ? or is that a crx ? i havent seen the car in a while but what i remember was it ripping up the streets, i'm in southside if thats your car but anyway..i have no idea on the tech information on this thread, just too lazy to pm

guys liam is the freakin man...you'll see he's the one that came up w/ the VAFC hack almost about a year ago.... Liam

Hey liam, hows that mf2 been working out for you ? For some reason I seem to remember reading something about reliability issues with that unit.

liam821

I havent used it in a while...but when i did use it was great. Although once when i got it wet it stopped working..and i ended up blowing up the car because i blow a vacuum line to a map sensor....but that wasnt a fault of the erl mf2.

All in all i was very pleased with it...it worked great once i got it tuned right.

I like the afc hack much better!
