hey guys, im coming from a prelude with a h22. Modded it for a few years and some guy wrote it off after i finished my project. Ended up buying a 92 eg hatch. Its a vx right now 93hp ecno vtec lol.

I recently purchased a completely rebuild d16z6 head. It was machine tested, resurfaced, tested for warpage, new valve seals, full valve job, typhooned, valves replaced, retainers replaced, valve springs replaced, cam replaced, old cam gear but its obviously good. I bought a new headgasket, timing belt, water pump, cam seal, intake mani gasket, plugs and wires (ngk). Im going to be buying a new intake manifold for it as well. Looking at blox.

Anyway, with the head completely new, the block in great condition, and the maintance completely out of the way i pretty much have a brand spanking new engine. I am going to be turboing this car come early spring. Its going to be running a tiny turbo, and be my autox, track, and dd car. its not the end of the world if it blows up so don't tell me it won't be a good dd i am well aware of what i am going to do to it.

I have not been able to get a straight answer. How much hp can i push out of a stock engine like this. Its going to be running 100%. I have been told 160-180whp, upwards to 200-220whp if the tune is amazing. i would be cool with 180whp if its possible. 200 would be optimal. It will be tuned with a hondata s300.

What problems do the d series engines run into with this kind of power? Common ones. H22's the ringlands take dumps on you for example. What do d series engines like to do to **** people off.

What size exhaust can i get away with. 2"? 2.5? i want to reduce the noise and i know the muffler has alot to do with this but i want it as quiet as possible. What intercooler piping is the best size for that power? again 2" or 2.5" ? Suggestions on a turbo that could spool by 2.5-3k and still pump out 180-200whp?

I'll be making a build thread in a couple months once everything starts coming together. Just clearing a few loose ends before i turbo the sucker. Sorry for the novel, but i really would appreciate it if someone could take the time and answer as many questions as possible. If you do, i will create another civic that the honda community will appreciate

Check the Boosted threads on sites such a d-series.org .
You can get about 200whp from a D-block with stock internals if youy put the time in with proper parts, installation and tuning.


As for exhaust noise, quietness has to do with the proper use of a resonator (or 2) and muffler. A stock catalytic converter will keep the noise level down a great deal, but suggesting the use of one probably isnt what you want to hear for a boosted car. Believe it or not, the turbo itself does a deal of muffling. Gasses passing thru the turbo wheel actually get diffused to some extent.

Dsm 450cc injectors will be more than enough right? I will make sure that i get them cleaned and tested so they are like new

DSM 450's should be fine, but need a resistor box the the low resistance, and they are known for a rough idle,

would a resistor box from a prelude work? I have a parts 4th gen with a bunch of parts left on it. What kind of injectors would you suggest?

also i plan on beefing up the suspension and tracking the car as stated above. This is what i have in mind. What do you guys think?

Skunk2 coilovers
Skunk2 rear lower tie bar
Skunk2 lower control arms
Skunk2 camber kits
Solid one piece front upper strut bar
Front and rear sway bars (undecided)

I was thinking about buying a complete bushing kit but i have heard they are a pain to drive in. I drove in my friends and it was pretty unpleasant. Really bumpy because the car was so damn stiff. Handled like a dream though.

I believe any honda resistor box will work (dont know if they must be obd compatible), the main point is to get the ohm's down. If you want to use the dsm's, they should be fine. If you dont want to hack and install the resistor box you can get a set of r/c enginering 450's (high impednace, so you dont need a resistor box) for around 350 on ebay. I will be using r/c 550-660 in my car when finish building.

yah i was thinking about the rc injectors. They are just a little bit more than i wanted to spend on injectors but i know it will save me the headache of hacking up a harness. Plus they are brand new.

im actually pretty excited to start this project. Civics cost nothing in comparison to preludes. The parts cost next to nothing. Even for brand name parts cost half as much as the same brand name prelude part.

Most say that 220whp is the limits for a stock d-series rod, those are the weakest point of the bottom end.

With a good, safe tune, you should be able to pass 200whp easily.

Syndacate

I don't really care how good they're tuned, running it past 200/210whp on stock internals lowers its reliability, I wouldn't push it beyond that, I mean "207 after tuning" is one thing, but I wouldn't be aiming for 220 before you even get to the dyno. Keep it under 200 on a "safe" tune and you should be perfectly reliable.

Unless you plan on changing the redline which flips the maximum HP the block can take completely around.

i don't plan on running over 200whp. Probably 190whp just becasue it will ease my mind.

This brings me to my next question. Are there any good tuners located near the canadian american boarder? I live in edmonton alberta and the only shop that is trust worthy is in calgary alberta about 400km away. If i am towing it all the way there, i might as well just go down to the states and get it tuned by a more competient shop. The tow is free so it wont cost me anything but gas.

Also, With the z6 head on my block what is the redline now? the vx goes to about 6200rpm before the limiter kicks in.
