Post D16z6 w/ SC14 supercharger
The victim for this build is a '92 Civic CX. I picked it up for free from my brother in law after he wrecked it twice in the nose. I drove this car back from Fairfax VA. to Casper Wyoming.
Some times running on 3 cylinders b/c of a hole in the sparkplug boot.
Image
After driving my hatch for about 3yrs as is and at one point even achieving 44.5mpg or 667miles on one tank of gas in town. I wanted to compete in my local auto-x events with a little bit more power. So I got a d16z6 w/ trans. out of a '94 EX coupe w/ unknown mileage.
Installed it w/ an Egay 6-puck clutch and chrome moly lite flywheel (11lbs.) and a cheap SS headers to make my exhaust easier to hook up. I had a buddy who gave me his homemade 2.5" exhaust which installed. I originally had no catylitic converter but after walking behind my car and about died from the fumes I installed on.
These pictures are of the SC14 I bought for $250. These s/c come out of '95 to '97 Toyota Previa. I got the idea to use one of these when I read about 1g MR2 use these to upgrade from their SC12 to SC14 on 1.6l 4age. And I own a '96 Previa AWD S/C. These pictures show where my original planned location until I realized I would have no room for my driver side cv-axle and the pulley was too close to the shock tower. Notice the a/c cluth pulley.

Image
The next two pictures give you an idea the size of the SC14.
Image
Image
I realize the only way to get this in was to take out the a/c system.
I started cutting the radiator support to make more room.
But after looking at my wife's hatchback the iI found tons room if I use a scissor jack to push the bottom of the rad support away from the engine back to its OE location.
Wires and hoses going every where. 1g bov, intercooler, piping, and coupler from a buddy for $65 helped. Three of those couplers are not being used I had the pipes welded incluing using my old cold air intake.
Image
Intercooler and s/c outlet manifold and airfilter. These SC14s comes with oil dipsticks. but I could mount it upright. Looking at the bypass tube and valve I had to duct tape them closed since I did not have way of controlling the bypass yet.
Image
Image
I wired the SC14 clutch pulley to the original a/c compressor clutch activation switch. And jumpered the pressure swith plug. Now the main power to my s/c was the a/c switch on my dash. I used the original a/c tensioner pulley assymbly. For the idler pulley I just used a longer bolt through the bottom bracket holding s/c. Long enough to use spacers to space the pulley out to line up with belt and pulleys.
Image
Image
I ran a hose (spare rad. hose) from the bov to the air filter assymbely
Image
I originally used 450cc DSM inj., resistor box, and a V-AFC. I know that the v-afc is junk but I did not have any parts to use to chip my ecu.
I drove this setup for 4 month with very little problems. Until my motor started making a familiar rod noise. I shut it of in my driveway and now I am building a new motor.
Which I'll post here when I start taking more pictures.

Motor plan includes:
D16z6 block already filled with devcon
Block will be have the deck milled 0.020in and bored and honed to a p2w of 0.004 to 0.0045in.
D16z6 crank stock
Vitara ycp pistons 75.5mm o/s w/ new Honda 75.5mm Rings. (for the rings thanks Jargon pistons from a HMT member's name I lost from the whole website snafu)
Used TT rods w/ new ARP 2000 bolts. (also from a HMT member's name I lost from the whole website snafu)
New stock bearings.
New Water pump
D16y8 cylinderhead will be used with a lite port matching. (thanks to Teng Vang I forgot his hmt name but thanks mang.)
Stock ported D16z6 intake w/ 880cc injectors. (thanks to Super Dipper).
I'm using a slightly modified H23a tb which helps a lot when not under boost compared to stock tb.

I'm planning on designing a new intake mani w/ 4 tbs and a plenumn w/ a 3" inlet. It will have provisions for 2 rows of inj. and larger fuel rails.
I plan on having a turbo on top of this setup or twincharge system I like to call it.
I plan on either using one of these:
Image
The green turbo is a used Mercedes diesil To4b unknown comp. w/ less than5k miles b/c the motor was replaced with a new turbo and the motor ran out of oil but did not damage the turbo.
The red turbo is a T0468 with a S-trim comp. New never used
The silver/natural turbo is a T0445 unknown comp. New never used
Image
Image
Image
Image
Image
Image
All three turbines are O-trim and have a split turbine housing.
I'm either going to use the red turbo with a blockoff plate on the inner port of the turbine housing or buy a T70 and sell these three turbos.
I'm also designing new inlet and outlet manifolds to the SC14 for both better flow and to give more room to clear the exhaust mani.
I'm either going to make a sinktrap of the 4-2 part of my header and mount the turbo at the same height as a topmount mani would w/ 3" downpipe and a wg on the sintrap pipe or get a top mount mani. made for me.

With the SC14 I have hit 18psig once, but I usually run around 10-12psi. at WOT and from 2k to 6k rpms.
I try not to over rev. the s/c b/c it has design limits of 10k continuous and 12k instanteous redline.
refer to: http://www.oguraclutch.co.jp/english/e_ ... _siyou.htm and http://www.mr2supercharger.com/SCblowers2 (look at the bottom of page.)
On the first link look at part# TX15
On the second link look at part # ‚s‚w‚P‚T
With the crank pulley to s/c pulley ratio of 1.4:1
I run my engine up to 6k =8.4k at the s/c. I do plan on installing a throttle switch similar to a NOS activation full throttle switch.
The SC14 is a 1440/rev = 84cid compare to a 46cid or 64cid JRSC super plus I use an intercooler. My intake temp. never go over 20 deg above ambeint.
With a JRSC 46cid on a D16z6 they start to heat the charged air considerably above 4k rpms.
So I would say SC14>JRSC in my book plus I spent less than $600 for this setup.
I never got to a drag strip yet but I know I can get in the 13sec in the 1/4 for sure maybe lower.
I had a buddy ride with me and counted a little over 5 sec. to go from 0 to 60mph.

As for the bypass where I hook the 1g DSM bov the hose runs to the inlet of my s/c already.
The bov is hooked up to the tb like on turbo applications. One of the problems with this bov is it does not release the compressed air fast enough.

I just copied and paste my setup from my original post on RealHomeMadeTurbo.com.
Here is the link http://www.realhomemadeturbo.com/forum/ ... opic=651.0

But if you guys have any questions or ideas just lmk.
I do bump on here at least once a day.

good job looks like you did your research.I have a couple t3/t4 that i would like to use on my 95 5.0.It has a sc on it now.I was thinking of turning headers upside down(15/8 mac shortie.)I would like to put 2 intercoolers(one behind fog light opening)on my car with nitrous just because i already have it and it has such a cold and dense air.it works great on my 302 sc motor.this is going in a 69351w(408) which had a much stronger block.keep up the good work

Yeah most homemade turbo mani. use headers either flipped forward.

I'm thinking of doing the same thing w/ my '82 'stang GT.
Mine will be carb. (1406 Edelbrock) but not sure yet.

OK here is some vids.  ;D

This all I can get with the C183 kodac Digi-Cam.  Thanks for HotRodLincoln for holding the camera and recording.  ;D

I'll try to get better vids soon. Along with the hack and weld of the inlet and outlet manifolds for my s/c.  ;D
