The Official SOHC Supercharger thread...
I see that there's a lot of people who wanna upgrade there stock sohc jrsc boost so
hopefully this isn't a double post but, http://www.aspracing.com/index.html makes em for $95, steel or aluminum (aluminum takes longer). Call and tell them what model your car is and what size blower pulley you want. I bought a 3.2" blower pulley that's gonna be on my D16Y8 with the JR crank so hopefully I see 9-10psi. It'll be here in 2-3 weeks so I'll post some pictures.

anyone having or had trouble with code 14 OBDO runs like dog *** but entire set up ran perfect once. accordin to my book and alldata it means idle air control or eacv wiring so the solenoids are good but there was a short in the wire betwwen the ecu and connector fixed that and still throws code. even when a different computer such as pm6 is used it still thros the same code and runs the same way.... anyone?

would it not even hold a constant throttle? like when you hold the throttle to what would be like 3 grand it just rapps between 3000 and 3700 with out just staying at a constant throttle an the tps is adjuste perfect.....
nope not at all and it drives like that too... cannot drive just thirty five... it always needs to be accelerating... its wierd... also i think it could be fuel pump so i will check fuel pressure and let ya know
Not identical. The EG kits have a 4 rib belt setup, and the EF kits (as well as the EK) have 3 rib setups. The EFs and EKs have interference issues with the shock tower. The EK's issues are even more pronounced than the EF.
my search skills suck, so here goes. does anyone know if i can upgrade from a m45 to a m62 blower? ive heard endyn's name thrown around about a conversion manifold, but cant find it.
Endyn used to offer a full M62 setup for the D16 not a conversion plate which btw, is long discontinued. I haven't heard of anyone making a conversion plate to allow M62 to bolt up. If it were that easy, we'd all be running them.
So i got my jrsc d16 running finally but ive got some issues. When i start it it revs up to about 3000 3500 rpm. Then it drops to 1000 and jumps to 2000 then back down to 1000. Now i know that sounds like simple vacuum leak but it gets worse. Ive found all the open vacuums and closed them but theres know difference. So i took off one of the vacuum hoses and put my finger over it and couldnt feel hardly any vacuum in it. I did this with other hoses and had the same outcome. I messed with the bolts that hold on the s/c to the manifold and they were loose. Is there a gasket that goes in between those that goes out often? Im kina stumped right now but i know i can figure it out but i need a starting point. Please gimme somthin to get the wheels turnin. THANKS

Good luck.
BTW if anyone needs a Y8 alternator bracket for the JRSC. I have a spare.
This is my Civic 99 EX EJ8 setup
D16y8 SOHC Stock Motor and Cylinder Head
Onsoku Cam Gear -1 retard
Jackson Racing @ 7psi
4x2x1 ebay header with no CAT and stock Exhaust and muffler
Cold Air Intake with Mushroom Style Air Filter
B16a Throttle Body 60mm
MSD Cap, rotor and Blaster SS Coil
Denso IK20 spark plugs
10mm NGK Spark Wires
Walbro 255lph fuel pump @ 60psi at idle
510cc Evo injectors
P28 ECU Tunned with Crome
German Glow Gauge
Glowshift Boost/AF Raio gauge and Oil pressure gauge
Green Vtec Light and Check Engine as Shift Light
Aluminum Radiator with Samco Silicone Hose kit
Motor and JRSC:

Car:





Dynojet 248e: Civic Ex OEM(weak) and Civic EX JRSC @ 7psi - 163.6hp/124.85lb/ft

Gtech Times: Civic Ex OEM(weak) and Civic EX JRSC @ 7psi (don´t have real track times)

Video (Before tunned at Dynojet)
Video (Tunned after Dynojet)
Have some questions for the other JRSC D16 owners:
This is the dyno and numbers that I should get with this setup?
How much gain I could have if change my Stock Exhaust and Mufller to a 2.5pol and free flow Muffler?
After my dyno I saw at the internet other D16 revving up to 7700rpm and gaining HP, so I expect to reach 170whp, is it safe with my stock block D16y8 and Head?
Thanks!

totally agree! love the supercharger sound but it was way cheaper for me to go turbo! but i am still interested if i can find a s/c kit for a good price!
Wow ! That is some info . Just read entire thread before hand . Just getting ready to rebuild my sohc zc for jrsc and wanted find out what was up .Had questions but not anymore . Thanks to all the old heads in advance .
I'm picking up a JRSC Kit for a 96-98 CX/DX/LX (989-210) this month. I was thinking of this setup at most:
3.8" 4 rib pulley
DSM 450cc injectors
walbro 255lph fuel pump
DC 4-1 one piece headers
no cat.
resonator
2.25" piping
magnaflow performance XL muffler
wideband 02 sensor and LC-1 controller
4bar map sensor
ARP head studs
stock Z6 head gasket
hondata intake manifold gasket
colder spark plugs
K&N stock replacement air filter
p28 chipped and dyno tuned on crome
I don't know if I'm going to rebuild the D15B in my EJ1 right now or buy a separate Z6 to rebuild while I still drive around. I live in cali so I want to keep it as legal as possible. Also if anyone has a 3.8" 4 rib pulley for sale let me know.

You will face issues with pulley alignment using the EK kit in an EG. The manifold used in the EK kits has offset mounting for the blower to go with the special EK JRSC crank pulley to make room for the belt around the driver's side shock tower.
